    priority claim
    [0001] This application claims the benefit of the filing date of US patent application Ser. No. 13 / 587,722, filed Aug. 16, 2012, entitled "Fluid Exchange Devices, Pressure Exchangers, and Related Methods."
    Technical area
    This invention generally deals with replacement devices. More particularly, embodiments of this invention relate to fluid exchange devices for one or more exchange properties (e.g., pressure) between fluids and the mixing of fluids, wherein the exchange device includes fixed exchange lines and one or more rotary valves.
    background
    [0003] Pressure exchangers are sometimes referred to as "flow-work exchangers" or "isobaric devices" and are devices for exchanging pressure energy from a relatively high pressure fluid system to a relatively low pressure fluid system. The term fluid as used herein includes gases, liquids and pumpable mixtures of liquids and solids.
    In some industrial processes, increased pressures are required in certain parts of the operation to achieve the desired results, with the pressure of the pressurized fluid subsequently being reduced. In other processes, some fluids used in the process are available at high pressures and others at low pressures, and it is desirable to exchange pressure energy between these two fluids. As a result, in some applications, economical improvements can be made if the pressure can be transferred efficiently between two fluids.
    For example, there are industrial processes wherein a catalyst is used at high pressure to cause a chemical reaction to occur in a fluid, and after the reaction has taken place, it is no longer necessary for the fluid to be under high pressure Pressure is required, but it is a fresh fluid supply under high pressure required. In such a process, a pressure exchange device may be used to transfer the pressure of the high pressurized fluid to the reaction for the fresh supply of lower pressure fluid so that the economy of the process is improved by requiring the delivery of less pump energy.
    Another example in which a pressure exchange device is used is the purification of saline using the reverse osmosis membrane process. In this process, an introduced brine stream is continuously pressurized and provided to a membrane array. The introduced brine flow stream is continuously split through the membrane array into a stream of highly concentrated brine (brine), which continues to be under relatively high pressure, and a purified stream of water at a relatively low pressure. While the high-pressure brine flow generally makes no sense as a fluid in this process, the flow-pressure energy it contains is high. A pressure exchange device is used to recover the flow pressure energy in the brine stream and transfer it to an introduced brine flow. After the transfer of the pressure energy from the brine stream, the brine is discharged at a low pressure to drain by the input brine flow under a low pressure. Thus, the use of the pressure exchange device reduces the amount of pump energy required to pressurize the input brine flow.
    U.S. Patent 4,887,942 and U.S. Patent 6,537,035 disclose a pressure exchange apparatus for transferring pressure energy from a liquid stream from one liquid system to a liquid stream from another liquid system. This pressure exchange apparatus has a housing with an inlet and outlet line for each liquid flow, and a cylindrical rotor which is arranged in the housing and adapted to rotate about its longitudinal axis. The cylindrical rotor is provided with a number of passages or bores that are parallel to the longitudinal axis and have an opening at each end. A piston or free piston may be inserted into each bore to separate the fluid systems. The cylindrical rotor may be driven by a rotating shaft or by forces transmitted by the fluid flow. Because multiple passages or bores are aligned with the inlet and outlet lines of both fluid systems at all times, the flow in both fluid systems is substantially continuous and uniform. Due to the nature of the device, a single rotating moving part can achieve high rotational and thus high cyclic speeds of the device, which in turn reduces the volume of the passages or holes in the rotor, thus resulting in a compact and economical device.
    U.S. Patent 3,489,159, U.S. Patent 5,306,428, U.S. Patent 5,797,429, and PCT Patent Publication WO 2004/111 509 each disclose an alternative arrangement for a pressure exchange apparatus having one or more fixed ones Replacement vessels with different valve arrangements used at each end of these vessels. These devices have the advantage that there is no clear limit to scaling in size and that, in the device of WO 2004/111 509, a leak between the flows under high pressure and under low pressure can be minimized. In each exchange vessel, a piston for separating the fluid systems can be used.
    Disadvantages of pressure exchange devices based on U.S. Patent 4,887,942 may include: At high flow rates, it may be necessary to increase the size of the cylindrical rotor, and there are limitations on the amount that such a rotor will move upwards as centrifugal forces will attempt to break the rotor, similar to the problems encountered in scaling flywheels to large sizes and high speeds; very small gaps between the cylindrical rotor ends and the inlet and outlet lines are required to maintain low leakage rates between the fluid systems under high pressure and low pressure, which leaks cause a reduction in efficiency and it is difficult to maintain these small gaps; when operating at relatively high rotational speeds, it may not be practicable to use a driven shaft to control the rotation of the motor, rather than nonlinear forces that can be efficiently reduced by the fluid flow that can efficiently reduce the flow area over which a particular device can be operated; and it may not be practical to use a piston in the passages in the rotor, thereby reducing efficiency through increased mixing between the two fluid streams.
    Disadvantages of pressure exchange devices based on US Patent 3,489,159 may include: the flow in both fluid systems is substantially non-continuous and uniform unless a large number of replacement vessels are used; these devices are generally limited to low cyclic speeds because of the linear or disconnected nature of the valves, thus requiring relatively large volume replacement vessels that increase cost and volume; and because of the multiple moving parts, these devices tend to be more complex and expensive to manufacture than devices based on U.S. Patent 4,887,942.

    Type (s) of the embodiment of the invention
    The illustrations presented herein are in some instances not actual views of particular devices, components, structures, elements or other features, but purely idealized illustrations used to describe embodiments of this disclosure. In addition, shared elements in the figures may retain the same numerical designation.
    Disclosed herein are fluid exchangers (e.g., a pressure exchanger) that can be used to exchange one or more properties between fluids.
    In some embodiments, exchangers are disclosed herein which are similar to and include the various components and configurations of the pressure exchangers illustrated in U.S. Patent Application Publication US 2009/0185 917 to Andrews, published July 23, 2009.
    Although some embodiments of this disclosure are illustrated as being used and employed as a pressure exchanger between two or more fluids, it will be apparent to those skilled in the art that the embodiments of this disclosure may be employed in other implementations, such as For example, substituting other properties (eg, temperature, density, etc.) between one or more fluids and / or mixing two or more fluids.
    Fig. 1 is a perspective view of one embodiment of an exchanger (e.g., a pressure exchanger 100), and Fig. 2 is another perspective view of the pressure exchanger 100 of Fig. 1 having a discharge portion. As shown in Figures 1 and 2, the pressure exchanger 100 may include a plurality of ports (e.g., four) for supplying fluid to and removing fluid from the pressure exchanger 100. For example, the pressure exchanger 100 may include a first port 102 of a first stream (e.g., acting as a high pressure inlet (HPI) 103) and a second port 104 (e.g., acting as a high pressure outlet (HPO) 105). The pressure exchanger 100 may also include a third port 106 of a second stream (e.g., functioning as a low pressure inlet (LPI) 107) and a fourth port 108 (e.g., acting as a low pressure outlet (LPO) 109).
    As shown, the pressure exchanger 100 is configured to allow fluid under high pressure to enter the pressure exchanger 100 (eg, through ports 102, 104) along the center of the pressure exchanger 100 (eg, along a longitudinal axis L100 or centerline of the pressure exchanger 100). enter or leave, while fluid under low pressure, for example, through ports 106,108 in a direction transverse to the longitudinal axis L100 or center line of the pressure exchanger 100 (for example, tangential to the rotation of the discussed below valve assembly in the pressure exchanger 100) enters the pressure exchanger 100 or this exit. In other embodiments, the pressure exchanger 100 may be configured to allow fluid under low pressure, for example, to enter and exit the pressure exchange 100 through ports 102, 104 along the center of the pressure exchanger 100 (eg, along the longitudinal axis L100 or centerline of the pressure exchanger 100) while fluid under high pressure enters and exits the pressure exchanger 100 through, for example, ports 106, 108 in a direction transverse to the longitudinal axis L100 or centerline of the pressure exchanger 100 (eg, tangential to the rotation of the valve assembly discussed below in the pressure exchanger 100).
    The pressure exchanger 100 has a housing 110 which forms the plurality of ports 102, 104, 106, 108. For example, the housing 110 of the pressure exchanger 100 may include end caps (eg, a first end cap 112 and a second end cap 114) having one or more ports formed therein. In some embodiments, each end cap 112, 114 may have two ports. For example, the first end cap 112 may include the first port 102 and the fourth port 108, and the second end cap 114 may include the second port 104 and the third port 106. That is, the first end cap 112 may include the HPI 103 and the LPO 109, and the second end cap 114 may include the HPO 105 and the LPI 107.
    In some embodiments, the end caps 112, 114 may be configured such that the first port 102 and the second port 104 (eg, the HPI 103 and the HBO 105) are aligned with an axis of the pressure exchanger 100 (eg, with the longitudinal axis L100 or center line). In other words, the end caps 112, 114 may allow fluid flow (eg, high pressure fluid flow) through the first port 102 and the second port 104 in an axial direction. End caps 112, 114 may be configured such that third port 106 and fourth port 108 (eg, LPI 107 and LPO 109 are aligned transversely (eg, perpendicularly) to an axis of pressure exchanger 100 (eg, longitudinal axis L100 or centerline) In other words, the end caps 112, 114 may allow fluid flow through the first port 102 and the second port 104 in a radial direction.
    In some embodiments, end caps 112, 114 may be approximately similar (eg, identical) and have similar components. For example, the end caps 112, 114 may be mutual mirror images to facilitate flow therethrough. In other words, the ports 106, 108 of the end caps 112, 114 may be positioned so that the rotation of a valve therein tends to draw fluid through the port 106, 108 or expel fluid from the port 106, 108. In such embodiments, the tangential alignment of ports 106, 108 of a valve assembly (eg, valve assembly 101 discussed in more detail below) may be rotated by fluid flow through ports 106, 108 (see, for example, FIG. 9).
    The housing 110 of the pressure exchanger 100 has a central portion 116 which extends between the end caps 112, 114. For example, each end cap 112, 114 may be coupled to the middle portion 116 at opposite axial ends of the middle portion 116. In some embodiments, end caps 112, 114 may be coupled to rods 118 attached to both ends of central portion 116. In other embodiments, the end caps 112, 114 as illustrated and described below may be coupled directly to the central portion 116 with reference to FIG. The end caps 112, 114 may terminate at each end of the central portion 116 with plates (eg, a first plate 120 and a second plate 122). For example, each end cap 112, 114 may terminate with a plate 120, 122 at each axial end of the pressure exchanger 100 and secured to the rods 118.
    The middle section 116 has a plurality of lines 124 for exchanging pressure and / or fluid between fluids passed through the ports 102, 104, 106, 108 to the pressure exchanger 100. For example, the conduits 124 may extend along the longitudinal axis L100 of the pressure exchanger 100 between the plates 120, 122. Each plate 120, 122 may be formed as a conduit holder having a plurality of openings formed in the plate 120, 122, each opening in the plate 120, 122 communicating with a respective conduit 124 for fluid communication between the ports 102, 104 , 106, 108 in the end caps 112, 114 and the conduits 124. In some embodiments, the conduits 124, as shown in FIG. 2, may be formed by separate conduits of the central portion 116 of the housing 110. In other embodiments, the leads 124 may be formed in a unitary central housing as illustrated and described with respect to FIG. 12.
    As best shown in FIG. 2, the pressure assembly 100 includes a valve assembly (eg, a valve assembly 101, described in more detail below) that rotates about the fixed leads 124. In other words, while the valve assembly 101 can rotate relative to the leads 124, the housing 110 of the pressure assembly 100 is configured to hold the leads 124 stationary as the valve assembly 101 rotates about the leads 124. In other embodiments, the pressure exchanger 100 may include a valve assembly 201 that is similar to the assembly discussed with respect to FIG. 8.
    The valve assembly 101 includes one or more valves (eg, a first valve 126 and a second valve 128) positioned on opposite sides of the conduits 124 to control fluid flow between the ports 102, 104, 106, 108 in the end caps 112, 114 and the lines 124 to regulate. For example, the valves 126, 128 may be rotatably mounted in the end caps 112, 114 and configured to selectively communicate with the conduits 124 of the central portion 116. In some embodiments, and as described in more detail below, the valves 126, 128 may be angularly positioned relative to each other (attached to the shaft 130, for example) to provide a phase shift. In some embodiments, the valves 126, 128 may include a metal, a metal alloy (eg, stainless steel), a polymer (eg, a thermoplastic), a ceramic, or combinations thereof.
    The valves 126, 128 may be coupled to a shaft 130 at the central portion 116 (for example, in sealing and sliding engagement with the plates 120, 122). For example, the shaft 130 may be coupled to and extend from the first valve 126, extending through the central portion 116 of the housing 110 (eg, along the longitudinal axis L100 of the pressure exchanger 100), and extending to and coupled to the second valve 128. In order for the valves 126, 128 to rotate relative to the central portion 116 (eg, relative to the conduits 124), the valves 126, 128 may rotate about the shaft 130, and the valves 126, 128 and shaft 130 may be relative to one or more Rotate portions of the pressure exchanger 100 (for example, the lines 124) or combinations thereof. In some embodiments, the pressure exchanger 100 may include a motor 132 (eg, an electric motor) to rotate the valves 126, 128 and shaft 130. In other embodiments, and as shown in FIG. 9, a motor 132 may be absent at the pressure exchanger 300, and the valves 126, 128 and, in some embodiments, the shaft 130 may be configured driven by the one from the pressure exchanger 300 via the ports 102, 104, 106 (not shown in FIG. 9, see FIG. 1), 108 to supply fluid flow in the end caps 112, 114. In still other embodiments, the engine may include a hydraulic motor.
    Fig. 3 is a perspective view of the valve assembly 101 for use with the pressure exchanger. As shown in Fig. 3, the valve assembly 101 is formed by the valves 126, 128 and the shaft 130 as shown and described above with reference to Figs. In some embodiments, the valves 126, 128 may be substantially similar (eg, identical). Accordingly, and as described herein with respect to FIG. 3, it can be seen that valves 126, 128 are substantially similar and each have the same features, although each feature may not be common to each valve 126, 128 as shown in FIG 3 is recognizable. Also, in other embodiments, the valves 126, 128 may not be identical, and may differ to provide different flow options to and from the conduits 124 (FIG. 2).
    Each of the valves 126, 128 has an axial port 134 for directing flow to and / or from the axial ports 102, 104 of the end caps 112, 114 (Figures 1 and 2) and one or more radial ones Ports 136 (for example, two opposing ports 136). The axial ports 134 may be positioned such that an opening of the port 134 extends along a plane perpendicular to the longitudinal axis L100 of the pressure exchanger 100 (FIGS. 1 and 2). The radial ports 136 may be positioned such that an opening of the port 136 extends along a plane that is parallel or at an oblique angle to the longitudinal axis L100 of the pressure exchanger 100 (Figures 1 and 2).
    The ports 134, 136 of each valve 126, 128 communicate with one or more openings on an inner surface 138 of each valve 126, 128 that provide selective fluidic communication with the conduits 124 (FIG. 2). For example, the axial port 134 of each valve 126, 128 may communicate with two opposing ports 140 (eg, the flow path from the port 134 may be shared for communication with the two ports 140). For example, each axial port 134 may extend substantially along (eg, completely along) the longitudinal axis L100 of the pressure exchanger 100 (FIGS. 1 and 2) to an associated opening 140 on the inner surface 138 of the valve 126, 128. The radial ports 136 of each valve 126, 128 may communicate with openings 142. For example, each radial port 136 may extend at least partially along the longitudinal axis L100 of the pressure exchanger 100 (FIGS. 1 and 2) to an associated opening 142 on the inner surface 138 of the valve 126, 128. In embodiments where the radial ports 136 are opposed (as shown in FIG. 3), the openings 142 are also opposite each other.
    Fig. 4 is a cross-sectional view of the pressure exchanger 100 of Figs. 1 and 2 showing a flow path of the radial ports 136 of the valve assembly 101. As shown in Fig. 4, the valve assembly 101 having the valves 126, 128 is rotated such that at least a portion of the radial ports 136 of each valve 126, 128 communicates with one or more conduits 124 of the pressure exchanger 100. For example, the apertures 142 communicating with the radial ports 136 of each valve 126, 128 may be sized such that each radial port 136 communicates with a plurality of adjacent conduits 124 (eg, at least two conduits 124, at least two conduits 124, etc.). The valve assembly 101 may allow one or more conduits 124 of the pressure exchanger 100 communicating with the radial ports 136 of each valve 126, 128 to communicate with the radial ports 136 while isolating from the axial ports 134 of each valve 126, 128 are.
    As further illustrated in FIG. 4, the radial ports 136 of each valve 126, 128 communicate with a port in the end caps 112, 114 (eg, ports 106, 108). As noted above, the valves 126, 128 and end caps 112, 114 may be similar or identical in some embodiments. Accordingly, port 106 (FIG. 1), which is not visible in FIG. 4, may resemble port 108. For example, the valves 126, 128 allow fluid to enter a cavity formed by the end cap 114 via the port 106 (FIG. 1) to substantially surround the valve 128. The fluid may then enter through the radial ports 136 of the valve 128, exit the valve 128 through the openings 142 in the valve 128, and enter one or more conduits 124. Similarly, fluid that may be the same fluid or different fluid supplied through port 106 (FIG. 1) may be from the one or more conduits 124 through ports 142 in valve 126 and through the radial ports 136 of the valve 126 may enter a cavity formed in the end cap 112 and may exit through a port of the pressure exchanger 100 (eg, port 108).
    FIG. 5 is a cross-sectional view of the pressure exchanger 100 of FIGS. 1 and 2 showing a flow path of the axial ports 134 of the valve assembly 101 through a cross-sectional plane that is transverse to the cross-sectional plane of FIG. 4. runs vertically. As shown in FIG. 5, the valve assembly 101 having valves 126, 128 is rotated so that at least a portion of the axial port 134 of each valve 126, 128 communicates with one or more conduits 124 of the pressure exchanger 100. For example, the apertures 140 communicating with the axial ports 134 of each valve 126, 128 may be sized such that each radial port 136 communicates with a plurality of adjacent conduits 124 (eg, at least two conduits 124, at least two conduits 124, etc.). As discussed above, the valve assembly 101 may allow one or more conduits 124 of the pressure exchanger 100 communicating with the axial ports 134 of each valve 126, 128 to communicate with the axial ports 134 while being separated from the radial ports 136 (FIG. 4) of each valve 126, 128 and the cavities in the end caps 112, 114 are insulated.
    The axial ports 134 of each valve 126, 128 communicate with a port in the end caps 112, 114 (eg, ports 102, 104). For example, the valves 126, 128 may allow fluid to enter through the port 102 in the end cap 112 and through the axial ports 134 of the valve 126. As also shown in FIG. 5, the axial ports 134 of the valves 126, 128 may distribute (eg, divide) the fluid flow to different channels 144. The fluid may then exit the valve 126 through the openings 140 in the valve 126 and enter one or more conduits 124. Similarly, fluid, which may be the same fluid or a different fluid supplied through port 102, may be routed from the one or more conduits 124 through orifices 140 in valve 128 and through axial port 134 of valve 128 to one in FIG End cap 112 formed cavity, and it can escape through a port of the pressure exchanger 100 (for example, the port 104).
    FIG. 6 is a partial, exploded perspective view of the pressure exchanger of FIG. 100 of FIGS. 1 and 2. FIG. As noted above, portions of the pressure exchanger may be similar or identical in some embodiments. Accordingly, in one embodiment, the exploded portion of the pressure exchanger 100 shown in FIG. 6 may include one of the end portions of the pressure exchanger 100. As shown in Fig. 6, a plate is shown which may be the plate 120 or the plate 122 of the central portion of the pressure exchanger 110. The central portion 116 of the pressure exchanger 110 may include a sealing plate 146 positioned between the plate 120, 122 and the corresponding valve 126, 128. The sealing plate 146 may form a seal (eg, an axial seal) between the valve 126, 128 and the central portion 116 having the conduits 124 and allow the valve 126, 128 to rotate relative to the stationary conduits 124 the leakage of fluid between these components is minimized. In other words, the sealing plate 146 forms a dynamic seal with the valve 126, 128, as the valve 126, 128 slides along the sealing plate 146. In some embodiments, the sealing plate 146 may include a metal, a metal alloy (eg, stainless steel), a polymer (eg, a thermoplastic such as polyetheretherketone (PEEK), a thermoplastic composite such as a polymer having fibers formed therein), a ceramic, or combinations have it.
    In some embodiments, the valves 126, 128 may be secured to the shaft 130 with an axial shaft nut 148 and key 150 received in the associated groove formed in the shaft 130 and the axial shaft nut 148. The ends of the shaft 130 may be covered with a sealing nut 152 to prevent leakage from the ports of the valves 126, 128 and / or at least partially inadvertent release of the axial shaft nut 148 (eg, configured as a clamping nut). In some embodiments, the coupling of the valves 126, 128 to the shaft 130 may be adjustable along the length of the shaft 130 to adjust the interface between the valves 126, 128 and the sealing plate 146. In other words, this means that the coupling of the valves 126, 128 to the shaft 130 can be adjustable (eg, by tightening and loosening the axial shaft nuts 148) to ensure that the valves 126, 128 suitably seal dynamically with the sealing plate 146, while still being able to rotate relative to the sealing plate 146. In some embodiments, the valves 126, 128 may be positioned to provide a selected gap (eg, a fixed sealing gap of, for example, 0.002 mm) between each seal plate 146 and associated valve 126, 128 rotating thereabove. In some embodiments, the valves 126, 128 and the sealing plate 146 may be in contact with each other.
    In still other embodiments, the valves 126, 128 may be secured to the shaft 130 to provide a self-adjusting gap between each sealing plate 146 and associated valve 126, 128 rotating thereabove. In other words, the valve assembly 101 in the pressure exchanger 100 can move axially relative to at least a portion of the pressure exchanger 100 (for example, the housing 110). In such embodiments, the pressure from the fluid flow through the pressure exchanger 100 (for example, through the valve assembly 101) may independently adjust the position of the valve assembly 101 in the pressure exchanger 100. In still other embodiments, the valves 126, 128 may be biased in sealing engagement with the seal plate 146 (eg, with springs, torque nuts, etc.). In still other embodiments, the valves 126, 128 may slide axially on the shaft 130, with the axial shaft nut 148 stopping the valve 126, 128 as it moves away from the seal plate 146 and the valves 126, 128 moving toward Plates 146 allows.
    The pressure exchanger 100 may include a journal bearing 154 that may be coupled to (eg, positioned over, integrally formed with, etc.) a portion of the valve 126,128. The slide bearing 154 forms a seal (eg, a dynamic radial seal) between the valves 126, 128 and a portion of the end caps 112, 114. In some embodiments, the slide bearing 154 may include an O-ring (for example, as shown in FIG. 14). , a lip seal or other energized seal configured to create a dynamic seal between the valves 126, 128 and a portion of the end caps 112, 114. In some embodiments, the seal plate 146 and slide bearing 154 may comprise a metal, a metal alloy (eg, stainless steel), a polymer (eg, a thermoplastic composite, polytetrafluoroethylene (PTFE), etc.), a ceramic material, or combinations thereof.
    FIG. 7 is a plan view of one embodiment of a valve assembly such as the valve assembly 101 of the pressure exchanger 100 of FIG. 2. Both valves 126, 128 of the valve assembly 101 are shown in FIG. 7, with the portions of the valves 126, 128 disposed behind other portions of the valve assembly 101 shown in phantom for clarity. As shown in Figure 7, the valves 126, 128 may be substantially similar (eg, identical) and angularly spaced from one another. For example, the valves 126, 128 may be connected to the shaft 130 such that one valve 126 is in a different angular position than the other valve 128. For example, the first valve 126 may be angular distance Θ1, (e.g., -45 ° to 45 °) from be offset second valve 128. Such displacement also displaces the openings 140, 142 formed in the inner surface 138 (Fig. 3) of each valve 126, 128. In some embodiments, the first valve 126 may be angularly offset by a positive distance Θ1, (eg, 0.01 ° to 10 °, 4 °, etc.) from the second valve 128 such that each opening 140, 142 of the first valve 126 rotates in a direction of the desired rotation of the valve 126, 128, with a corresponding opening 140, 142 of the second valve 128 (for example, an opening 140, 142 of the second valve 128, at least partially aligned with the opening 140, 142 of the first valve 126) is) in a direction along the longitudinal axis L100 (Figures 1 and 2). In some embodiments, the first valve 126 may be offset at an angle by a negative distance Θ1, (e.g., -10 ° to -0.01 °, -4 °, etc.) from the second valve 128, such that each opening 140, 142 of the first valve 126 upon rotation retracts a corresponding opening 140, 142 of the second valve 128 in a direction of intended rotation of the valve 126, 128.
    As shown in FIG. 7, a rotationally leading edge 156 of one or more openings 140, 142 in the first valve 126 may be offset from a rotationally leading edge 158 of one or more openings 140, 142 in the second valve 128 , In other words, in one direction along (eg, parallel to) the longitudinal axis L100 (FIGS. 1 and 2), a portion (eg, smaller portion) of the one or more openings 140, 142 in the first valve 126 is separated from a portion (eg a smaller portion) of one or more openings 140, 142 in the second valve 128, while another portion (eg, a larger portion) of one or more openings 140, 142 in the first valve 126 may be offset with a portion (eg, a larger portion ) may be aligned by one or more openings 140, 142 in the second valve 128. In some embodiments, each rotationally leading edge 156 of each opening 140, 142 in the first valve 126 may be offset from each rotationally leading edge 158 of each opening 140, 142 in the second valve 128.
    With reference to FIGS. 3 and 7, a displacement between the openings 140, 142 formed in each valve 126, 128 may provide a phase shift between the valves 126, 128. In other words, the offset between the openings 140, 142 formed in each valve 126, 128 changes the time during the rotation of the valves 126, 128 when the openings 140, 142 with one or more conduits 124 communicate at each end of it. For example, upon rotation of the valves 126, 128, the opening 140 of the first valve 126 would be in communication with a selected conduit 124 prior to the corresponding opening 140 of the second valve 128 as the valve 128 is angularly spaced (eg, leads) by a distance Θ1 the opening 140 of the first valve 126, the corresponding opening 140 of the second valve 128 by an angular distance Θ1). As described below, such a configuration may be used to phase shift pressure spikes in the pressure exchanger 100 (eg, a positive pressure spike when a low pressure fluid and / or a low pressure area is communicated with one or more conduits 124 , and a negative pressure spike when the one or more conduits 124 are communicated to a high pressure area and / or high pressure fluid) that may function to reduce the occurrence of cavitations in the pressure exchanger 100.
    FIG. 8 is a perspective view of another embodiment of the valve assembly 201 for use with a pressure exchanger, such as the pressure exchanger 100 of FIGS. 1 and 2. As shown in Figure 8, the valve assembly 201 may be similar to the valve assembly 101 discussed above with respect to Figures 3, 6, and 7, and may have the same or similar components and configurations. As shown, the valve assembly 201 may include valves 252 having a substantially butterfly-like shape. For example, an outer portion of the radial ports 254 of the valves 252 may not be bonded by a portion of the valves 252 (as compared to the radial ports 136 of the valves 126, 128). In some embodiments, the axial ports 256 of the valves 252 may include separator dividers 258 between each of the channels 260 extending from the axial ports 256 of the valves 252.
    FIG. 9 is a cross-sectional view of one embodiment of a pressure exchanger 300 with a missing motor. FIG. As described above, the pressure exchanger 300 may be without a motor, and the valves 126, 128 (and in some embodiments, the shaft 130) may be configured for rotation, driving through the pressure exchanger 300 via the ports 102, 104, 106 (not shown in Fig. 9, see Fig. 1), 108 in the end caps 112, 114 supplied fluid flow takes place.
    10 is a partial cross-sectional view of one embodiment of a pressure exchanger 400 having one or more elements to minimize (eg, at least substantially) mixing between fluids in one or more portions of the pressure exchanger 400 (eg, in the conduits 124) to prevent). As shown in FIG. 10, the pressure exchanger 400 may include one or more line pistons 402 positioned in the lines 124 of the pressure exchanger 400 for mixing fluid at a first end of the pressure exchanger 400 (eg, via the port 102 in the end cap 112 supplied and removed via port 108) and fluid at a second, opposite end of pressure exchanger 400 (eg, fluid supplied via port 106 (FIG. 1) in end cap 114 and removed via port 104) , In some embodiments, the conduit pistons 402 may be shaped to have a circular cross section (eg, a sphere, a sphere, a cylinder). In some embodiments, the conduit pistons 402 may include a metal, a metal alloy (eg, stainless steel), a polymer, a ceramic material, or combinations thereof. Such line pistons 402 may be implemented in any of the exchangers disclosed herein.
    11 is a cross-sectional view of one embodiment of a pressure exchanger 500 having one or more elements to minimize (e.g., at least substantially) mixing between fluids in one or more portions of the pressure exchanger 400 (eg, in the conduits 124) prevent). As shown in FIG. 11, the pressure exchanger 500 may include one or more baffles 502 positioned in the conduits 124 to at least partially prevent the flow of a fluid (eg, a high pressure fluid) into the conduit 124. Such baffles 502 may be implemented in any of the exchangers disclosed herein.
    Fig. 12 is a perspective view of one embodiment of an exchanger (for example, a pressure exchanger 600). As shown in Figure 12, the pressure exchanger may be substantially similar to the pressure exchangers 100, 300, 400, 500 discussed above with reference to Figures 1 to 11, and may be the same or similar components (eg, valve assemblies 101, 201). and configurations. For example, the pressure exchanger 600 includes end caps 112, 114, each of which may have two ports coupled (eg, fixedly coupled) to an enclosed central portion 612.
    Figs. 13 and 14 are cross-sectional views of the pressure exchanger 600 of Fig. 12 in a direction transverse to the longitudinal axis and along the longitudinal axis, respectively. As shown in FIGS. 13 and 14, the pressure exchanger 600 may include a housing 610 (eg, a stator housing) having the central landing 612. As shown, the middle section 612 may have a unitary structure (i.e., not a plurality of lines as shown in Figure 1) having all of the lines 614 (e.g., twelve lines) formed therein. The central portion may be coupled to plates 620 similar to those discussed above with reference to FIGS. 2 and 6. As also shown in FIG. 14, the conduits 614 may include a necked-out portion 616 near each end of the conduits 614 that has a reduced inside diameter.
    In some embodiments, the stator housing 610 may be formed of a conductive material (eg, a metallic material) or a non-conductive material (eg, a non-metallic material such as a non-conductive polymer). In embodiments that implement a conductive stator housing 610 and a motor 132, fluid flow through the conduits 614 may be used to cool the motor 132. As shown in FIG. 13, the motor 132 may be mounted directly in the stator housing 610 (eg, in direct thermal communication therewith).
    Referring again to FIG. 5, a first fluid stream may be supplied through ports 100 through pressure exchanger 100 (or pressure exchanger 300, 400, 500, 600). It should be understood that while specific reference is made to the pressure exchanger 100, the pressure exchangers 300, 400, 500, 600 may all operate in a similar or identical manner as described herein. The rotary valve 126 allows the passage of fluid through the axial port 134 and into the channels 144 formed in the valve 126. As the valve 126 rotates, the channels 144 are positioned in selective communication with one or more conduits 124 that allow at least a portion of the fluid to pass through the openings 140 and enter the conduits 124.
    As also shown in FIG. 5, fluid from lines 124 may exit lines 124 through rotary valve 128 (eg, may be expelled by the fluid supplied to lines 124 further above as described). For example, fluid from lines 124 may pass through openings 140 in valve 128, through which passages 144 pass to axial port 134 and exit valve 128 and pressure exchanger 100 via port 104.
    As shown in Figure 4, a second fluid stream is passed through port 106 (Figure 1) to pressure exchanger 100 and into the cavity in end cap 114 (for example, simultaneously with the first fluid stream supplied in Figure 5). The rotary valve 128 allows the fluid to pass from the cavity in the end cap 14 into each radial port 136 in the valve 128. As the valve 128 rotates, the radial ports 136 are positioned in selective communication with one or more conduits 124, at least one Section of the fluid is allowed to pass through openings 142 and into the lines 124.
    As further illustrated in FIG. 4, fluid may exit the conduits 124 from the conduits 124 through the rotary valve 128 (eg, it may be expelled by the fluid supplied to the conduits 124 further above as described). For example, fluid from lines 124 may pass through openings 142 in valve 126, pass through radial ports 136, and exit via port 108 from the cavity of valve 126 in end cap 114 and pressure exchanger 100.
    As described above with respect to FIG. 7, in some embodiments, the valves 126, 128 may be angularly offset. In such an embodiment, the offset between the valves 126, 128 may shift the communication of the first valve 126 and the second valve 128 with each line 124. For example, and as described above, a portion of an opening 140, 142 of the first valve 126 may be communicated with a portion of a conduit 124 at a first end of the conduit 124 before a portion of an opening 140, 142 of the second valve 126 communicates with the same line 124 is communicated at an opposite end of the line 124 when the valve assembly 101 is rotated about the line 124 (or vice versa, depending on the selected angular offset). Such offset delays forces applied to the conduit 124 by the fluids at each of its sides. For example, the angular offset in the valve assembly 101 acts to control the timing between the supply of fluid through the ports 140, 142 in the first valve 126 at one end of the conduit 124 and the removal of fluid from the conduit 124 through the ports 140, 142 in the second Valve 126 to move at an opposite end of the line 124.
    When the pressure exchanger is used to exchange pressure between fluids, the delay in high pressure fluid delivery from a high pressure surface to one end of the conduit 124 and the removal of fluid to a relatively low pressure surface may cause the pressure to increase by these events caused peak forces to shift. For example, when the fluid flow is stopped under low or high pressure through a conduit 124 through the valves 126, 128, a pressure increase occurs in the conduit 124 at one end of the conduit and a pressure drop across the other end of the conduit 124 Cavitation when the pressure drop falls below the vapor pressure of the fluid. By offsetting the two valves 126 and 128, this pressure drop can be reduced or eliminated, so that the occurrence of cavitation in the pressure exchanger 100, 200, 300, 400, 500, 600 decreases.
    As another example and as shown in Figure 5, when the exchangers described herein are implemented as pressure exchangers, high pressure fluid may be supplied by a first fluid stream to the pressure exchanger 100 through the port 102 (i.e., HPI 103). The rotary valve 126 selectively directs the fluid under high pressure into one or more conduits 124 via the axial port 134. Pressurize (pressurize) fluid previously through port 106 (FIG. 1) (ie, LPI 107). and through the rotary valve 128 and radial ports 136 has been routed to the conduits 124, may be at least partially expelled from the conduits 124 by the fluid under high pressure and the now pressurized fluid previously in the conduits 124 pass through the valve 128 via the axial port 134 and exit from the pressure exchanger via the port 104 (ie, HPO 105).
    When the valve assembly 101 is moved 90 degrees as shown in Fig. 4, fluid under low pressure is applied to the conduits 124 via port 106 (Fig. 1) through the cavity of end cap 114 and through the rotating valve 128 and the radial ports 136 out. The fluid under high pressure, previously routed to conduits 124 via port 102, valve 136, and axial port 134 as described above, is now in lines 124 under relatively low pressure, since this is already utilizing used fluid has been to pressurize the previously led to the lines fluid under low pressure with pressure. This spent fluid may be at least partially expelled from lines 124 and may pass valve 126 and into the cavity of end cap 112 and exit the pressure exchanger via port 10 8 (i.e., LPI 109).
    As noted above, FIGS. 4 and 5 illustrate positions of the pressure exchanger 100 and the valves 126, 128 in 90 degree increments of the valve assembly 101. Accordingly, it can be seen that the pressure exchanger 100 incorporates the above-described supply of Fluid under low pressure and under high pressure, the exchange of fluid pressure and the discharge of the fluid under low pressure and high pressure in half a turn of the valve assembly 101 can perform. In other words, the above-described supply of fluid under low pressure and under high pressure, the exchange of fluid pressure, the discharge of the fluid under low pressure and under high pressure at each rotation of the valve assembly 101 can be done twice (2 times). Stated another way, this means that FIG. 4 can represent the valve assembly 101 and the pressure exchanger 100 with 0 degree and 180 degree increments and that FIG. 5 shows the valve assembly 101 and the pressure exchanger 100 with 90 degree and 270 degree increments. Can represent degree increments. Accordingly, the processes described above with respect to FIG. 4 may occur simultaneously at 0 degree and 180 degree increments of the valve assembly 101 and the pressure exchanger 100, while the processes described above with respect to FIG. 5 may also occur simultaneously at 90 -Degree and 270-degree increments of the valve assembly 101 and the pressure exchanger 100.
    As another example, and as shown in Fig. 5, when the salt water solution pressure exchangers described herein are implemented using the reverse osmosis membrane process, fluid under high pressure (e.g., high concentration brine) may be absorbed high pressure) through a first fluid stream to the pressure exchanger 100 through port 102 (ie, HPI 103). The rotary valve 126 selectively passes the high concentration brine under high pressure to one or more conduits 124 via the axial port 134. Low pressure pressurized fluid (eg, an at least partially purified water stream) previously flowed through the port 106 (FIG. 1) (ie, LPI 107) to conduits 124 may be pressurized by the high concentration brine under high pressure, and may be at least partially expelled from conduits 124 and directed through valve 128 via axial port 134 and exit the pressure exchanger 100 via port 104 (ie, HPO 105).
    Upon movement of the valve assembly 101 through 90 degrees, as shown in FIG. 4, a purified stream of water (pressurized) is fed to the conduits 124 at low pressure via the port 106 (FIG. 1). The high-concentration, high-pressure saline solution, which had previously been passed via port 102 to lines 124 as previously described, is now in lines 124 and is now a spent high-concentration, low-pressure saline solution. This spent high concentration saline solution under low pressure may be at least partially expelled from the conduits 124 and may exit the pressure exchanger via port 108 (i.e., LPI 109).
    It should be noted that the processes described above are considered to be somewhat ideal conditions for fluid and / or pressure transfer. It will be appreciated that all different fluids having different pressures and compositions may not be completely routed to or removed from the various sections of the pressure exchanger in each step.
