Abstract
Oil-water separation apparatus having a flow-through chamber containing a block of foam filter material regenerable by squeezing, a pair of perforated end plates located on either side of the foam block within the chamber at least one of which responds to applied pressure to squeeze the foam, and a flexible envelope of impervious material surrounding the foam block between the block and the inside walls of the chamber and connected at each end to the plates to avoid channeling and friction between the foam block and the walls of the chamber.
Claims8
Oil-water separation apparatus comprising a housing having an inlet and an outlet end;
- said inlet end having an inlet for introducing an oil-water fluid into the housing, said outlet end having an outlet for removing separated oil from the housing and an outlet for removing separated water from the housing;
- a pair of perforated plates axially spaced within the housing intermediate its ends, one of which is fixed in the housing and the other is movably mounted within the housing, said plates forming between them and with the inner wall surface of the housing a flowthrough separation chamber;
- porous filter material that is regenerable by compression located within the chamber;
- an envelope of flexible, impervious material surrounding the outer surface of the porous material adjacent the inner wall surface of the separation chamber, said envelope having an outer dimension less than the dimension of the inner wall surface of the chamber and being conducted at one end to said movable plate and at the other end adjacent the fixed plate to form an annular space around the enveloped porous material between the envelope and the inner wall surface of the chamber that can be pressurized with fluid in opposition to the pressure of flow of fluid through the chamber, said porous filter material being oversized in an uncompressed state with respect to said dimension of the envelope so that it is compressed into the envelope;
- and means for moving under pressure the movable plate with respect to the fixed plate so that the porous filter material and its surrounding envelope can be axially compressed within the chamber.
