FLOTATION HYDROCYCLONE Russian patent published in 2012 - IPC B04C5/04 B03D1/14 

FIELD: process engineering.

SUBSTANCE: invention relates to separation of inhomogeneous fluids by centrifugal forces, particularly, to flotation hydrocyclones to be used in chemical, petroleum and other industries. Proposed hydrocyclone comprises cylindrical tank with cover and porous permeable sidewall, annular collector to feed gas into said tank, branch pipes to feed suspension in said tank, those to discharge foam and feed gas into collector, and unloading device. Micro pores of said sidewall represent horizontal cylindrical through channels with radial direction at tank top and tangential direction at tank bottom. Direction of micro pores from radial to tangential varies as distance from tank cover increases while direction of tangential pores complies with suspension feed direction. Gas feed branch pipe is arranged tangentially at collector bottom and its direction is aligned with that of micro pores at tank bottom.

EFFECT: higher separation efficiency.
