    DEVICE AND METHOD FOR MIXING AND REPLACING FLUIDS
    The invention relates to an apparatus and a method for mixing and exchanging fluids, in particular for the gasification or degassing of liquids.
    For the degassing or degassing of liquids numerous devices are known be¬kannt. These devices usually work with large interfaces between the liquid and the gaseous phase in order to be able to transport large quantities of gas into and out of the liquid in the shortest possible time.
    Devices are also known for gassing or degassing and for filtering liquids, in which between a gaseous phase and a liquid phase a membrane is arranged, which is permeable to the gas and impermeable to the liquid.
    Such a device is e.g. in document EP 0 226 788 B1. This device includes a semi-permeable membrane in a wall between a gas flow and a fluid flow. In particular, a semipermeable membrane is also mentioned for bubble-free gassing of the liquid, for which purpose the semipermeable membrane is permeable to a gaseous medium to be admixed. In this case, however, the problem arises that the penetrating through the semipermeable membrane into the liquid gas is removed only very ineffective by the liquid, as forms on the membrane surface, an interface layer in the liquid. This boundary layer is practically stationary at the Membranoberflä¬che. By wetting and Durchnetzen of the membrane or the membrane pores by the Flüs¬sigkeit the formation of such a stationary boundary layer is favored.
    The invention has for its object to improve the mass transfer to a semipermeable membrane between a first fluid and a second fluid.
    In order to achieve this object the invention according to a first aspect provides a device for mixing and exchanging fluids, having a first chamber and a second chamber adjoining the first chamber, the first chamber being one of at least a first one Fluid and a second fluid in a mixing fluid flow direction permeable mixing chamber with static mixing elements and the second chamber is a fluid flowing from the second fluid fluid supply chamber or fluid discharge chamber, wherein at least in part of the boundary region between the volume of the first chamber and the volume of the second chamber, a semipermeable membrane is arranged , which is impermeable to molecular or molecular agglomerates of the first fluid and permeable to molecules or molecular agglomerates of the second fluid, characterized in that the membrane is made of a material or coated with a material to which at least the molecules or Mo Lekül agglomerates of one of the two fluids have a low affinity.
    According to the first aspect, the formation of a stationary boundary layer is made difficult by one of the two fluids on the membrane.
    In order to achieve this object, according to a second aspect, the invention provides a device for mixing and exchanging fluids, comprising a first chamber and a second chamber adjacent to the first chamber, the first chamber having at least one first fluid and one second fluid Fluid in a mixing fluid flow direction durch¬ flowable mixing chamber with static mixing elements and the second chamber is a fluid flowing through the second fluid fluid supply chamber or fluid discharge chamber, wherein at least in part of the boundary region between the volume of the first chamber and the volume of the second chamber is arranged a semi-permeable membrane, which is impermeable to molecules or molecular agglomerates of the first fluid and permeable to molecules or molecular agglomerates of the second fluid, characterized in that the semipermeable membrane is an elastic membrane which is supported on a support wall provided with a plurality of holesis stretched.
    According to the second aspect, it is also possible to make the formation of a stationary boundary layer by one of the two fluids on the membrane more difficult, by generating a pulsating pressure difference between the two sides of the membrane by pulsating pressurization of one of the two fluids.
    Preferably, the measures according to the first aspect and the second aspect are combined, i. E. the membrane is made of a material or is coated with a material to which at least the molecules or molecular agglomerates of one of the two fluids have a low affinity, and the semipermeable membrane is an elastic membrane which has one of a plurality of Holes provided support wall is clamped.
    The semipermeable membrane may be a hydrophobized (water repellent) membrane. In this case, wetting or wetting of the membrane by a polar liquid such as e.g. Water difficult.
    The semipermeable membrane may also be an oleophobic (oil repellent) membrane. In this case wetting or wetting of the membrane by a non-polar liquid, e.g. Oil difficult.
    Preferably, the semi-permeable membrane is an oleophobic and hydrophobized (oil-repellent and water-repellent) membrane. In this case wetting or permeation of the membrane by a non-polar liquid, e.g. Oil and by water sword.
    Preferably, the gas-permeable membrane of the inventive device is a polymer membrane permeable to gas molecules such as O 2, N 2, CO 2, which is preferably applied to and bonded to a porous support material. The effective pore size of the gas-permeable membrane is preferably in the range from 0.1 nm to 10 nm, while the carrier material can have a much larger effective pore size.
    As the material for the gas-permeable membrane, one of the following polymers is preferably used: cellulose acetate (CA), cellulose nitrate (CN), cellulose ester (CE), poly-sulfone (PS), polyethersulfone (PES), polyacrylonitrile (PAN), polyamide (PA), polyimide (PI), polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), polyvinyl chloride (PVC), polyurethane (PU).
    The thickness of the gas-permeable membrane is about 1 pm to 300 pm, preferably 10 pm to 200 pm.
    The carrier material for stabilizing the gas-permeable membrane may be a non-woven material, a textile material, e.g. of polyester, or another porous material whose effective pore size is many times greater than the effective pore size of the gas permeable membrane.
    The support wall may have circular holes and / or slot-shaped holes. Through the hole diameter or slot widths on the one hand and by the tension of the clamped elastic semi-permeable membrane, a flattening of the membrane sections stretched over the hole openings can be achieved by said pulsation become. As a result, the material throughput at the membrane can be increased and the membrane can be freed of deposits on the membrane. For this purpose, the low-frequency pulsation can be assisted by high-frequency oscillations (ultrasound).
    Conveniently, the first chamber within the device defines a continuous (contiguous) mixing chamber volume and the second chamber within the device is formed by separate sub-chambers with a respective partial volume of the fluid supply chamber or fluid discharge chamber, the sub-chambers upstream of the device into one Open fluid supply manifold and downstream of the device in a fluid discharge manifold lead.
    Preferably, the sub-chambers of the second chamber are transversely to the mixing fluid flow direction of the first chamber extending transverse channels, the channel walls provided with a plurality of holes supporting wall and a clamped on the support wall elastic membrane as a semipermeable membrane. These cross channels are both obstacles / baffles of the static mixing chamber and distributors for the second fluid for its delivery (e.g., fumigation) or its removal (e.g., degassing).
    Preferably, spaced transverse channels are provided with a circular or mitpolygonförmigem channel cross-section, wherein the transverse channels preferably parallel to each other.
    In order to optimize the packing density with transverse channels, preferably a first plurality of transverse channels with a first channel cross-sectional area are provided and a second plurality of transverse channels with a second channel cross-sectional area are provided, preferably the transverse channels of the first plurality of transverse channels and the first second plurality of transverse channels are arranged uniformly distributed in the first chamber. In this case, it is advantageous to use a ratio between a second channel cross-sectional area and a first channel cross-sectional area in the range from 1/10 to 5/10.
    In a particularly advantageous embodiment, a pressure source is in fluid communication with the first chamber or with the second chamber, which can generate a variable pressure. This pressure source allows pulsations, which leads to a "fluttering" of the elastic membrane in the area covered by the tensioned elastic membrane, whereby the passage of the second fluid through the membrane is favored for its introduction into the first fluid (eg fumigation) or its Removal from the first fluid (eg degassing).
    Conveniently, the transverse channels are secured in the region of their respective first end to a first carrier (e.g., first wall plate) and extend therethrough, the first carrier and the transverse channels together forming a first assembly of the device. Furthermore, it is expedient for the transverse channels of the first assembly to extend through openings in a second carrier (eg second wall plate) in the region of their respective second end, the second carrier forming a second assembly of the device together with further walls of the first chamber , This allows a quick disassembly and assembly of the device for maintenance purposes (cleaning, membrane change).
    Preferably, the transverse channels form the static mixing elements of the first chamber, i. the device is a static mixer whose baffles are hollow and communicate (partially) with the mixing chamber via the membrane of the invention (semipermeable).
    The invention also provides a method of mixing and exchanging fluids using the apparatus described above, wherein a first fluid and a second fluid are delivered through the first chamber (mixing chamber) and the second fluid through the second chamber is promoted through.
    The method can be used to Begasen a liquid, wherein a liquid-gas mixture is passed through the first chamber and the gas is passed through the second chamber, the pressure of which is greater than the pressure of the liquid-gas mixture in the first chamber ,
    The method can also be used for degassing a liquid, wherein a liquid-gas mixture is passed through the first chamber and the gas is passed through the second chamber, the pressure of which is lower than the pressure of the liquid-gas mixture in the first Chamber.
    Preferably, during gassing or degassing, the pressure in the first chamber or the pressure in the second chamber is pulsed. There are essentially two types of operation, with which the elastic semipermeable membrane spanned on the perforated support wall is deflected by pulses or fluttering.
    According to a first variant of the gassing, the membrane is deflected only in the region of the holes of the support wall perpendicular to the support wall. This type of "local" flattening / vibration of the membrane is favored by high membrane tension and high viscosity of the liquid with which the first chamber is completely filled.
    According to a second variant of the gassing, the membrane is deflected over the entire area provided with holes of the support wall perpendicular to the support wall. This type of "global" fluttering / vibration of the membrane is favored by low membrane stress, low viscosity of the liquid and when the first chamber is only partially filled.
    The pulsed membrane movements perpendicular to the perforated support surfaces not only favors the gassing or degassing of the liquid in the first chamber, but also impulses are transferred to the liquid flowing in the first chamber. The second gas-carrying chamber may also be subdivided such that a first part of the sub-chambers or the transverse channels communicate with each other and another part of the sub-chambers or transverse channels, which is hermetically separated from the first part, communicate with one another. The second chamber may be divided into several such parts. The respective parts of the second chamber can then be pulsed to each other with a time delay, whereby the flow behavior of the liquid in the first chamber can be influenced.
    Particularly advantageous in the method is the use of a device with hydrophobic membrane, wherein the liquid dissolved in water, emulsified in water or suspended in water substances. This can be used e.g. aqueous sweetener masses comprising sugar molecules dissolved in water. In particular, mention should be made here of the microbial release of frosting.
    Also particularly advantageous in the method is the use of a device mitoleophobierter membrane, wherein the liquid dissolved in fat or oil, emulsified in fat or oil or suspended in fat or oil substances. This can be used e.g. fat-based / oil-based confectionery masses, the sugar particles suspended in fat or oil and e.g. Kaβkaopartikel contain micro-aerate and micro-vent. In particular, mention should be made here of the micro-deaeration or micro-deaeration of chocolate.
    Further advantages, features and applications of the invention will become apparent from the following description of a non-limiting Ausführungs¬beispiels reference to the drawing, wherein Fig. 1 shows a first embodiment of the inventive device as Schnitt¬ drawing a part of the device ; FIG. 2 shows the first embodiment of the device according to the invention as a sectional drawing of the device; FIG. and Fig. 3 shows a second embodiment of the device according to the invention as
    Sectional drawing of the device shows; and Fig. 4 shows an enlarged detail of the detail C of Fig. 3.
    In Fig. 1 a first embodiment of the device according to the invention is shown as a sectional drawing of a part of the device. 1 shows a detail of the device for mixing and exchanging fluids, in particular for venting or degassing a liquid F with a gas G. The sectional plane (drawing plane) runs parallel to the prevailing or prevailing flow direction of the fluid F in a first chamber 2. This flow direction is indicated by the meandering thick lines with arrows P1. From the device only a section is shown. Partial chambers or transverse channels 4 extend through the first chamber 2 and are bounded by tubular walls 6 with holes (not shown). Stretched over the perforated tubular walls 6 is an elastic membrane 7 which is permeable to the gas G and impermeable to the liquid F. The flow direction of the gas G in the case of the gasification of the liquid F is indicated by the respective twelve arrows P2 at each perforated pipe 6. The device shown here can also be used for degassing. In the case of degassing, the direction of the arrows P2 would be reversed.
    In practice, further sub-chambers or transverse channels 2 can be arranged along the flow direction P1 upstream and downstream of the illustrated section and transversely to the flow direction P1 to the left and right of the section shown darge.
    The housing of the first chamber 2 and the tubes of the transverse channels 4 may be made of metal, in particular of stainless steel or anodized aluminum, or of a polymer, in particular of polyester, e.g. Polyethylene terephthalate, or consist of polycarbonate.
    The gas-permeable membrane (not shown separately) is a polymer membrane permeable to gas molecules such as 02, N 2, CO 2, which is applied to a porous support material (not shown separately) and connected thereto. Their effective pore size is in the range of 0.1 nm to 10 nm, while the carrier material has a much larger effective pore size. The size of the "pores" of the carrier material is expediently a multiple of the effective pore size of the membrane and is preferably in the range of 0.1 pm to 10 pm. This ensures that large molecules, e.g. Fat molecules or sugar molecules of food masses, or for agglomeration (clustering) tending water molecules can not pass the membrane, while the small, nichtagglomerier¬ten gas molecules can easily pass through the membrane 7.
    As material for the gas-permeable membrane, one of the following polymers can be used: cellulose acetate (CA), cellulose nitrate (CN), cellulose ester (CE), polysulfone (PS), polyethersulfone (PES), Polyacrylonitrile (PAN), polyamide (PA), polyimide (PI), polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), polyvinyl chloride (PVC), polyurethane (PU). Particularly preferred gas-permeable Membranmate¬rial are PS (repellent surface) and PU (high ductility). The thickness of the gas-permeable membrane is about 100 pm.
    As carrier material for stabilizing the gas-permeable membrane, a non-woven material, a textile material, e.g. polyester, or another porous, but elastically extensible material whose effective pore size is much larger than the effective pore size of the gas-permeable membrane alone.
    The elastic membrane 7 is a hose-like structure and can be mounted in a stretched state on the tubular walls 6 of the transverse channels 4.
    The essential operating parameters for the gassing and degassing of the liquid Fmit gas G are: effective pore size of the membrane 7, pressure difference between the flüssigkeits¬ leading first chamber 2 and the gas-conducting second chamber 4, Strömungsgeschwindig¬keit the liquid F, TemperaturA / iskosity the liquid F, cross-sectional shape of the transverse channels 4 (eg circular, lenticular, polygonal, in particular triangular or sechseckför¬mig), pressure difference amplitude and frequency of the pulsation of the gas G and / or the liquid F.
    In the fumigation or degassing of liquids, which are liquids with dissolved in water, emulsified in water or suspended in water particles or which are liquids dissolved in fat or oil, emulsified in fat or oil or suspended in fat or oil particles, operating temperatures of about 10 ^ to about 100 ^ occur. At these temperatures, the above-mentioned polymer materials are stable and are therefore suitable for gassing and / or degassing in such liquids.
    In Fig. 2, the first embodiment of the device according to the invention is shown as a sectional drawing of the device. 2 shows a section, parallel to the prevailing direction of flow of the liquid F, of the device for mixing and exchanging fluids, in particular for venting or degassing the fluid F with a gas G. The sectional plane (drawing plane) runs parallel to the predominant or previ- ous flow direction of the liquid F in the first chamber. 2
    At the upstream end, the device has an inlet 11 which opens into the first chamber 2. At the downstream end, the device has an outlet 12, which opens out of the first chamber 2. This flow direction is indicated by the meandering thick lines with arrows P1.
