    Vibrating filter-plate assembly device
    The present invention relates to a vibrating device adapted for vibration of a filterplate assembly, the filter-plate assembly being adapted for continuous vibrationdriven filtration, where said vibration device comprises a vessel housing, said vessel housing comprises a vessel pressure chamber, said vibration device comprises a filter plate assembly, said filter plate assembly comprises a plurality of rigid planar rectangular filter plates, said filter plates comprise one or more permeate channels and one or more permeate exits, said one or more permeate exits extend perpendicular to the filter plate assembly through said vessel housing adapted for permeate to exit the vessel housing, said filter plate assembly is rigidly mounted inside said vessel pressure chamber, said vibrating device comprises at least one retentate inlet adapted for a retentate stream to enter the vessel housing and at least one retentate outlet adapted for a retentate stream to exit the vessel housing, said vibrating device comprises a vibration motor, said vibration motor is adapted to provide a vibrating motion to the vessel housing.
    Field of the Invention
    The invention relates to fine filtration, microfiltration and ultrafiltration using membranes, typically subjected to a tangential flow, and especially to providing a robust and sanitary fouling-preventing filtration device, capable of being configured to filtering from 50 micron down to microfiltration and ultrafiltration.
    The media to be filtered is vibrated relative to the filter surface and can at the same time pass freely between the filter plates so that free flow filtration is obtained, and the media to be filtered can be highly viscous and even contain larger particulate impurities, as long as the media does not block the free flow passage between plates.
    The term permeate is used for the media that has passed through the filter, and the term retentate relates to the media to be filtered.
    The term fine filtration applies to filtration through slits or holes in the filter plates of 5 to 50 microns, whereas microfiltration usually applies to particle sizes between a few hundredths of a micrometer and tens of a micrometer and is carried out at low differential pressure from just above zero to a few bars. Fine filtration is often used as safety filter for process equipment. Micro filtration is for example used for sterile filtration of milk. Ultrafiltration is for example used for separating large organic molecules from mineral molecules or small organic molecules, and in the ultrafiltration process a higher differential pressure of 1-15 bars may be needed.
    When filters are used in a cross flow configuration, the media to be filtered is pumped at speeds of typically 2 to 5 meter per second across the surface of the
    DK 2017 70092 A1 filter in order to keep solids from building up and depositing on the filter and to keep the smallest possible boundary layer above the filter surface, hereby keeping the filter openings free and functional for a longer time in operation.
    The same cleaning functionality of membrane achieved in cross flow configuration can be achieved in a vibrating filter-plate assembly device by moving the filter surface relative to the media to be filtered.
    Description of the Prior Art
    The efficiency of a filter surface in flux per square meter is often not very high, as optimal flux is only obtained in a hydrodynamic, homogeneous configuration with a clean membrane and where concentration polarization of media close to the filter surface is avoided.
    A submerged device (CN105709602(A)) is described as an axial vibrating flat-sheet membrane, and this invention achieves a high flux from a vibrating movement of a flat filter plate relative to the media to be filtered. The media is situated in a fixed open vessel and it is understood that the filter plates can move freely while the media is still. The invention is mechanically complicated and will be difficult to pressurize or it will be complicated even to keep the system closed. Controlling concentration can also be problematic as flow to the membrane surface is not controlled in the open vessel.
    Round discs vibrating around a central axe are described in a number of Patent applications, such as CN204544009 or CN203507822. These are efficient vibrating systems, allowing high shear of membrane to media. However, these complex constructions have a tendency to break down, and additionally, the initial costs for a device are high.
    Submerged assemblies are typically used for Membrane Bio Reactors, and a number of prior designs are available, typically large flat sheet elements (TW200920471, US2013043189) with little focus on cleanability, as they operate with waste water anyway, or guard filters for very clean water. These systems are open systems to outside air, as “vibration” of the membrane is achieved through scrubbing with air bubbles, and only very low cleaning impact and low flux is achieved.
    WO2015114141 discloses a filt er-plate assembly configured for cross-flow filtration. An embodiment is illustrated in figure 5. This filter-plate assembly comprises a plurality of plastic molded planar rectangular filter plates (3) and one or more permeate exit (4), where the filter plates comprise a first and a second rigid surface, the surfaces comprise perforations (31), the surfaces enclosing a volume, the volume constitutes one or more permeate channel (39), whereby the
    DK 2017 70092 A1 perforations (31) are fluidly connected to the one or more permeate exit (4) through the permeate channels (39), characterized in that the filter plates comprise a protrusion, the protrusions of the plurality of filter plates combined form the permeate exits (4) from the filter plate assembly.
    In the above disclosed technique, as substantial flow of media is to be filtered, the retentate must be maintained in the assembly in order to keep the flow turbulent, as it is desirable to keep the filter surface clean, thereby maintaining high flux through the membrane in a continuous filtration process.
    Description of invention:
    It is an objective of the present invention to provide a vibrating filter-plate assembly device having a simple construction with optimized free flow filter capacity, capable of maintaining a high flux in a continuous filtration process.
    This is achieved by said vibrating device comprising one or more flexible volume chambers, said one or more flexible volume chambers being filled with gas, said one or more flexible volume chambers being adapted to expand and/or compress the volumes of the chambers inside the vessel housing allowing the retentate in the vessel chamber to move in parallel relative to the surface of said filter plates, when said vessel housing comprising said filter-plate assembly is subjected to a vibrating motion.
    Hereby, a simple construction is obtained by use of a limited number of components and the numerous advantages of the filter-plate assembly can be utilized in a simple cost-effective device.
    The volume of the gas-filled chambers may expand or/and compress and the retentate may be moved relative to the filter-plate assembly to allow continuous free surfaces such that the filters are not clogged by residue.
    In an embodiment, the vibrating movement of the filter-plate assembly and vessel is achieved through oscillating air feed to the air cushions, where by the air cushions also work as a vibrating motor.
    In an embodiment, the feed is entered in one corner of a rectangular filter-plate assembly and the concentrate is exited in the opposite corner. An additional deaeration exit in the upper sider can be used for deaeration of the vessel. This allows for a high concentration to be achieved in a one-pass flow. If a uniform retentate is wanted, this can be achieved by circulating concentrate from the previously described exit back to the vessel entry side.
    DK 2017 70092 A1
    In an embodiment, the filter feed pressure and air cushion pressure is adjusted to be the same, maximizing the efficiency of the air cushions. In all designs, caution must be taken to avoid a higher feed pressure than allowed in vessel designs.
    In an embodiment, the device is cleaned by substituting feed with rinse water or cleaning media and increasing flow over the filter by circulating the media at high flow rates from inlet to outlet while maintaining the rinsing function through vibration.
    In an embodiment, the feed is provided by a tank with air or gas under pressure, and the pressurized gas acts as a feed pump, pressing the feed into the filter device. This feed system can provide a stable feed at very low cost and using only simple off the shelf elements.
    In an embodiment, the feed is provided by a tank wherein a sterile bag contains the feed media, with air or gas under pressure, and the pressurized gas acts as a feed pump, pressing the feed into the filter device. This feed system can provide a stable, sterile feed at very low cost and uses only simple off the shelf elements.
    In an embodiment, the vibrating vessel is formed in see-through materials or with see-through inspection glasses whereby the filter-plate assembly and media can be visually inspected during filtration process and cleaning.
    Materials used for the filter-plate assembly device are typically polymeric or copolymeric thermoplastics or any other suitable material that can withstand the media to be filtered, the temperature span needed, typically 5-55 degree Celsius (°C) as well as the medias used for cleaning the Filtration Unit. Also, the choice of material must foresee thermal expansion and rigidity of the unit and be sustainable to pressure and vibration. Preferred execution is a vessel in stainless steel, polycarbonate or polypropylene, and filtration plates in molded plastic, such as polypropylene and with a polymeric membrane used as fine filter, all materials readily accessible in food-grade versions on the market.

    Figure 1 illustrates one embodiment of an external view of a vibrating device (50). In the illustrated embodiment, the permeate exits (4), the entry (7), deaeration (10), exit connection (9) and back mix connection (8) of the filtration device is on the same side of the device as the pressure valve (12,13) connects to the gas cushion chambers. The vibration motor (11) is illustrated as mounted in one end of the device, and the device itself is suspended in flexible supports (6) in form of springs allowing for axial movement of the device. The vibrating movement affects the vessel housing (1) to be moved in a direction parallel to the extent of the planar surfaces of the filter plates (3), hereby keeping the filter surface of the filter plates free and clean during the filtration process.
    Figure 2 shows a cross-sectional view of one embodiment of a vibrating device (50). In the illustrated embodiment, the filter-plate assembly with permeate exits (4) is placed in the retentate chamber (5). The air cushions are established as flexible gaskets (16, 17) separating the retentate in the vessel pressure chamber (5) from the flexible volume chamber (14,15) or gas cushion chambers. Both the vessel pressure chamber (5) and the gas-filled flexible volume chambers (14,15) are formed as part of the vessel housing (1). The vibration motor (11) is illustrated as mounted in one end of the device, and the device itself is suspended in flexible supports (6), such as springs allowing for axial movement of the device and in the given embodiment the movement would be right to left to right given the positions of the flexible gaskets in relation to the filter-plate assembly (2). The filter-plate assembly (2) comprises a membrane area (21), which is fixed inside the vessel housing via the permeate connections (4) as these go through the side wall of the vessel housing (1) and outside the device (50). The filter-plate assembly is held in place with hollow screws that can at the same time fix the filter-plate assembly mechanically in the device and lead permeate out through the protruding permeate exits.
    Figure 3 illustrates a filter-plate assembly (2) that comprises a stack of 3 hollow filter plates (3).The surface of each rigid, flat, filter plate is covered by a fine filter membrane (21) on both sides. In the embodiment, the 3 filter plates (3) are connected at a distance defining by the bonding points (38) and protrusions at the permeate exits (4). The protruding permeate exits are fused together forming a permeate manifold from the three hollow filter plates (3) connecting to the permeate exits (4). The permeate exits leads permeate out of the vessel housing (1)· The filter-plate assembly (2) forms an open rigid free flow structure allowing for vibration of the filter-plate assembly parallel to the filter plates while the free access allow for movement of media to be filtered in relation to the filter plates (3).
    Figure 4 is an example of functional arrangement of the filter-plate assembly device connected to peripherals for operation. The filter-plate assembly (2) is placed in the pressure withstanding vessel pressure chamber (5). The vessel housing comprises a see-through panel allowing inspection of filter surface inside the vessel housing
    DK 2017 70092 A1 (1). The retentate stream enters in one corner through entry for retentate (7) and exit in the opposite corner through exit for concentrate (9). The device is suspended in springs allowing for the vibration motor (11) to impose the axial movement of the device in a direction parallel to the surface of the filter plates as shown with the two-way arrow.
    The feed is in the shown embodiment pumped from the feed tank (19) by gas pumped into the feed tank by a pump, and the gas pressure pumps the feed into the retentate chamber (5) via the feed entry (7). The same gas that pumps the feed is connected to the cushion chambers (14, 15) whereby the pressure is the same in the retentate chamber (5) and the cushion chambers, allowing for a movement of the retentate in relation to the chamber during the axial movement of the device (50) as the air cushions (14, 15) are squeezed or expanded. The feed pressure is adapted to the application and for microfiltration, the pressure is generally below 1.5 bar, while for ultrafiltration, the pressure is typically between 2 and 4 bar. While initially filling the device, the retentate chamber (5) can be deaerated via a high placed deaeration connection (10). In the shown embodiment, the size of the feed tank can be adapted to needs or filled with more feed during a pause in the filtration process. In a not shown embodiment, the feed is pumped into the device by a suitable feed pump and gas in the flexible volume chambers (14,15) can be entered via valve connections (12, 13) and balanced with the vessel pressure by separate means.
    The flexible volume chambers can be formed as individual balloons in the retentate chamber (5). However, for improved hygiene and as shown in the embodiment, the gas filled flexible volume chambers (14,15) are formed as sealed-off parts of the vessel, where a flexible gaskets separates the cushion volume from the retentate volume. The cushion chambers are optimally placed on opposite sides of filter-plate the assembly and in the direction of motion when the vessel housing is vibrated to allow for optimal movement of retentate in relation to the planar surfaces of the plates in the filter plate assembly.
    Permeate exits the device through connections (4) while new feed is entered at (7). Retentate can be drained continuously from exit (9) or the feed can be left concentrated in the chamber (5). In figure 4, the vibrating device (50) comprises a mixing pump (20) as illustrated, which is connected to the retentate exit (9) and to a back mix connection (8) and this pump can be used during operations to homogenize the retentate, or to ensure mixing during cleaning of the device.
    Figure 5 illustrates one embodiment of the Filtration Unit formed by a fused stack of filter plates (3) where each filter plate is made by bonding two half plates (32, 33). In the illustrated embodiment, the one permeate exit (4) of the Filtration Unit is at the end of the filtration area (6) and the filtration area is shown without a fine filtering element covering the numerous slit shaped perforations (10). As indicated, a number of channels (9) connect to the permeate exit inside the filter plate and the perforations lead to these channels. The permeate exit from the unit can be
    DK 2017 70092 A1 sealed off at one side of the stack, depending on need for exit area. The slit or gap between filter plates, form the free entry area for media to be filtered.
    The filter-plate assembly illustrated in figure 5 comprises a plurality of planar, rigid filter plates and one or more perpendicular permeate exits. These permeate exits extend through the vessel housing wall through a sealing permeate connection, hereby mechanically fixing the plate assembly rigidly in the vessel. The vessel is vibrated in the same plane as the plates with a vibration motor with amplitude of typically 2-25 mm at frequency between 5 and 50 Hz. The vessel includes one or more air cushions formed as flexible volume chambers or balloons, typically two, one in each side of the vibrating direction and on each side of the filter plate assembly, allowing the media to be filtered to move relative to the filter surface as the filter-plate assembly is moved with the vibrating vessel and the air cushions are squeezed or expanded to allow for the relative movement of the retentate.
    The vessel is typically mounted on or hanging from springs or elastic mounts allowing for the vibrating movement.
    The vibrating motor is typically a motor driven eccentric weight or an eccentric piston connection or pneumatic piston, but other means are also available.
    The vessel has to be of a robust design that can sustain the vibration as well as the required internal pressure, as the internal pressure corresponds to the trans membrane pressure, given that permeate can flow unrestricted from the permeate exit(s).
    The vessel design is typically adjusted to tightly enclose the filter-plate assembly to avoid larger dead volumes in the vessel.
    This filter-plate assembly comprises a plurality of plastic molded planar rectangular filter plates (3) and one or more permeate exits (4), said filter plates comprise a first and a second rigid surface, said surfaces comprise perforations (31), said surfaces enclosing a volume, said volume constitute one or more permeate channels (39), whereby said perforations (31) are fluidly connected to said one or more permeate exit (4) through said permeate channels (39), and where the filter plates comprises a protrusion, said protrusions of said plurality of filter plates combined forms said permeate exits (4) from the filter plate assembly.
    In an embodiment, the one or more of said filter plates (3) comprises two half filter plates (32,33), said half filter plates are bonded together at the periphery of the filter plates, and being identical in shape. The filter plates may comprise an additional filter sheet (21) positioned and bonded adjacent to said perforated surface of the filter plates.
    In an embodiment, the one or more permeate exits (4) extends perpendicular to the plane defined by the extent of said filter plates (3), and wherein the filter plate comprises bonding points (38) for bonding two adjacent filter plates, said bonding points together with the protruding exits (4) defining the distance between two
    DK 2017 70092 A1 juxtaposed filter plates, and the filter-plate assembly (2) forms a rigid singular assembly through fusing of the bonding points and protruding exits.
    In an embodiment, the filter-plate assembly (2) comprises actuation means for mechanical actuation of the filter-plate assembly in a plane parallel to the extent of the filter plates (3).
    In an embodiment, the filter-plate assembly (2) comprises a plurality of filter plates (3) and a housing, where the filter plates are situated parallel juxtaposed having the perforated surface facing the perforated surface of an adjacent filter plate, said housing encompassing said plurality of filter plates forming a square or rectangular entry for a media to be filtered and a similar retentate exit.
    In an embodiment, the filter-plate assembly comprises a plurality of plastic molded planar square or rectangular filter plates (32,33) and one or more permeate exits (4) , the filter plates (32,33) comprises a first and a second rigid surface, the surfaces comprise perforations (10), the surfaces enclosing a volume, the volume constitute one or more permeate channels (39), whereby the perforations (10) are fluidly connected to the one or more permeate exit (4) through the permeate channels (39).
    It goes without saying that different modifications may be made to the examples described without departing from the scope and spirit of the invention.
    It shall be noted that the overall design hereby gives possibility to have many square meters of filtration area in one compact Filtration Unit.
    All parts can be of food and pharmaceutical grade material with traceable origins, making the Filtration Unit suitable for human food consumables and the likes. The materials used are preferably of a plastic material that can be reused by re-melting or burned as a clean fossil-like fuel.
    The parts of the unit can be produced by 3 D printing or sintering of other means.
