FILTER FOR CONTINUOUS FILTRATION OF SUSPENSION UNDER PRESSURE Russian patent published in 2018 - IPC B01D24/32 B01D33/21 B01D33/48 

FIELD: technological processes.

SUBSTANCE: invention relates to a filter for continuously filtering a suspension under pressure. Filter for continuous filtration of a suspension under pressure, comprising a pressure vessel; rotating filter elements located in the pressure vessel, where the filter element is configured to pass through one filter cycle for each rotation; filter zones in liquid and gaseous phase; filtrate channels which connect the filter elements; separate filtrate outlets for each zone and a device for controlling individual filtrate zones by means of a distribution disc, which comprises filtrate outlets for the liquid and gaseous phases, characterised in that in the direction of the filtration cycle before the release of the filtrate of the liquid phase, a venting zone is provided, wherein the venting zone is connected to a separator tank through a separate pipeline.

EFFECT: uniform sediment formation and the elimination of shock pressure fluctuations.
