Name of the invention Filtration device with porous ceramic plates
Abstract
A filtration device includes a filter stack with a plurality of porous ceramic plates, which are axially spaced from each other to define a plurality of axially spaced radial flow areas. In one example, the filter stack is installed in the housing. In another example, a plurality of porous ceramic plates alternates between the second group of porous ceramic plates nested with the second group of porous ceramic plates. In another example, at least one of the sides of the porous ceramic plate defines a plurality of radial grooves arranged in a radial array.
- A filtering device, including a shell, the shell includes a first fluid port and a second fluid port, a filter stack, the filter stack is installed in the shell and is written to filter the fluid flow between the fluid ports, wherein the filter stack defines a central flow channel connected with the first fluid port, wherein the filtering device includes a peripheral flow channel, The peripheral flow channel is fluidly connected with the second fluid port and is limited between the filter stack and the shell. The filter stack comprises a plurality of porous ceramic plates, which are axially separated from each other by a plurality of spacers in the axial direction of the filter equipment to define a plurality of axially separated radial flow areas, Each porous ceramic plate includes a thickness extending between the first side and the second side of the porous ceramic plate, and each porous ceramic plate also includes a central hole extending through the thickness of the plate, wherein the central hole of the porous ceramic plate is positioned along the central flow channel, The plurality of axially spaced radial flow regions alternate between the first group of radial flow regions and the second group of radial flow regions along the central flow channel in the axial direction, the first group of radial flow regions is open to the central flow channel and closed to the peripheral flow channel, the second group of radial flow regions is closed to the central flow channel and open to the peripheral flow channel, and wherein, At least one of the first side and the second side of at least one of the plurality of porous ceramic plates defines a plurality of radial grooves arranged in a radial array around the corresponding holes of the porous ceramic plate.
porous ceramic filter - The filtering device according to claim 1, is characterized in that the plurality of spacers includes flexible spacers, and the filter stack is compressed in the axial direction, while the flexible spacers bias the corresponding porous ceramic plates axially to each other, so as to maintain the corresponding spacers between the porous ceramic plates.
- The filtering device according to claim 1, is characterized in that, The plurality of spacers comprises a first group of spacers that close the peripheral flow channel relative to the first group of radial flow areas and a second group of spacers that close the central flow channel relative to the second group of radial flow areas.
