CARTRIDGE FILTER Russian patent published in 2010 - IPC B01D27/08 

FIELD: process engineering.

SUBSTANCE: invention relates to device intended for filtration of neutral and aggressive fluid of mechanical impurities, particularly to cartridge filters and can be used for micro filtration in all industrial branches wherein high-efficiency cleaning of fluids and gases from dispersed particles is required. Proposed filter comprises housing divided by tube plate into top and bottom chambers, filtration vertical cartridges with protective cases with their open ends secured in tube plate and branch pipes with gates. Said protective cases are arranged in top chamber that makes an initial fluid chamber, and made from tight material with open, top and bottom ends jointed to tube plate and filtration cartridge open top ends, respectively. Filtration cartridge bottom open ends are jointed to tube plate made from permeable material and located below outlet branch pipe to separate lower, purified fluid, chamber from lower part of initial fluid chamber communicated with its lower part via inner hollow cylindrical channels of filtration cartridges.

EFFECT: higher efficiency, ease of manufacture.
