MEMBRANE FILTER FOR CLEANING LIQUID MEDIUM FROM MECHANICAL IMPURITIES Russian patent published in 2017 - IPC B01D29/00 

FIELD: technological processes.

SUBSTANCE: membrane filter is represented comprising a vertical housing with a bottom and a cover, a filter element installed under the cover, a deflector disposed coaxially with the longitudinal axis of the housing and having the form of an axisymmetric geometrical figure, the cross section of which is reduced in the direction towards the bottom, inlet and exit nozzles, output through the bottom, an outlet nozzle passing through the cover, and the valves on the inlet, outlet and exit nozzles, characterized in that the device is additionally equipped with an atomizer, installed coaxially the longitudinal axis of the housing, wherein the deflector is fixed on the bottom surface of filter element, wherein the structure of flow part between the deflector and the atomizer if selected from the condition taking into account the relationship of between area of flow part flow passage between the deflector and the nozzle, mass flow rate of cleaned liquid, its density, and the dimensional empirical coefficient.

EFFECT: decreasing the number of forced regenerations of the surface of filter membrane for a fixed period of time.
