Abstract
The invention relates to a filtration device for deep-bed filtration which is easier to handle and enables filter module(s) to be changed and disposed of easily. The filtration device has a casing with at least one filter module (1) inserted in the casing with filter elements (10, 10′, 10a′, 10b′) made from deep-bed filter materials stacked on top of each other. The filter elements have at least one internal structure (17) formed by a perforation (20) wherein the boundary surface of the perforation (20) formed by the deep-bed filter materials (12) creates a through-flow surface (11) for filtrates or non-filtrates. At least one end plate (52, 53) has at least one inlet and/or outlet.
Claims21
Filtration device with a housing and with at least one filter module which is inserted into the housing and which has two end plates, of which at least one end plate (52, 53) has at least one feed and/or discharge opening (56), and several filter elements located in between, the housing having openings for supplying the unfiltered material and for removing the filtered material, and the filter module (1) has filter disks (10, 10′, 10a′, 10b′) of deep-bed filter material which are stacked on top of one another and which have at least one inner structure (17) formed by an opening (20), the boundary surface of the opening (20) formed by the deep-bed filter material (12) forming a flow surface (11) for the filtered material or the unfiltered material, characterized in that the filter elements are filter disks (10, 10′, 10a′, 10b′), at least one filter disk (10, 10′, 10a′, 10b′) of the filter module (1) having an opening (21) which extends as far as the peripheral surface (19) of the filter disk and which produces a connection to the inner structure (17) of the filter disk (10, 10′, 10a′, 10b′).
