Multiple cell filter having a gas discharge

Industrial filter comprising filtering cells and a distributor collecting and distributing fluids from the cells, said distributor comprising essentially a distributing part and a collecting part sliding relative to one another with a cyclic movement, the collecting part being divided into chambers and compartments bounded by partitions, said compartments communicating with one or a plurality of intake and discharge devices for gases and liquids, the chambers being isolated and communicating each with a sucking or pressurizing device, the collecting part comprising in communication with each cell, cavities constructed to open in sequence during the cyclic movement, in front of each one of said compartments and chambers in such a way that during each cycle, each cell communicates in sequence with each one of said compartments and chambers and introduces into said compartments and chambers said gases and liquids from said cells, said filter being improved in that each one of said compartments is provided on the one hand at the bottom thereof with at least one outlet for discharging liquid, said outlet lying substantially below that level where the cavities open and on the other hand, at least one passageway constructed to extend from a level above that of the introduced liquid towards a gas-sucking device in such a way as to suck said gases while causing the gases and liquids to separate and go along different paths inside the compartments, means being provided to return to the original compartment those liquids which might have entered said passageways so as on the one hand, obtain at the distributor outlet, liquid-free gases and on the other hand, collect thtough the discharge openings but liquids which are substantially free from undissolved gases.
