SEPARATOR OF PARTICLES IN CIRCULATION OF LIQUID WITH DOUBLE EFFECT OF EXTRACTION, METHOD AND DEVICE FOR BIOLOGICAL PURIFICATION OF LIQUID Russian patent published in 1999 - IPC

FIELD: separation of particles contained in treated liquid. SUBSTANCE: separator has cylindrical body provided with means for pressure building-up to create forced vortex flow in it. Body in its base has circular channel, deflector and chamber for particle trapping. Deflector forms central ascending vortex current of treated liquid. Body upper part has axial outlet pipe for discharge of axial column of treated liquid from body. This device is distinguished by the fact that deflector has at least one central flat part, means for regulation of its longitudinal position to change and regulate the value of flow area of circular channel, and also by the fact that axial outlet pipe is extended downward with member for regulation flow to form flow channel of circular section. EFFECT: higher purification efficiency. 21 cl, 18 dwg
