VORTEX SEPARATOR OF COMPRESSED GAS Russian patent published in 2020 - IPC B01D45/12 B04C3/00 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to gas, gas processing, chemical and oil industry and can be used in processes and devices for separation of liquid from compressed gas flow. Vortex separator comprises cylindrical housing (1), upper (2) and lower (3) bottoms, inlet branch pipe (4) for gas-liquid mixture, fixed axially symmetrically on upper bottom (2), drain branch pipe (6) for discharge of separated liquid, located in lower bottom (3), outlet branch pipe (5) of clean gas, located on lower bottom (3), and outlet collector connected to it for collection of cleaned gas (7) is located inside cylindrical housing (1), is fixed axisymmetrically on its lower bottom (3) with formation of annular niche (11). Input section of outlet header (7) is located in central part of cylindrical housing (1). Tangential swirler (8) located at inlet branch pipe (4) is formed by vertical radial blades limited by discs (9) and (10) from above and from below. On outer surface of outlet header (7) along its entire height there is at least one edge (12). In front of inlet cross-section there is swirler damper (13) arranged in outlet header (7). Proposed device provides local reduction of dynamic gas head in zone of high concentration of separated liquid phase in annular niche between header (7) and housing (1) of separator, which eliminates removal of already separated liquid into outlet header (7). Rib or ribs (12) on outer surface of collector (7) reduce tangential component and full flow rate in annular niche (11), thereby increasing flow rate of gas-liquid mixture, in which there is a mud calk and there is an upward film-like flow on the outer surface of outlet collector (7).

EFFECT: technical result is improved quality of cleaning of compressed gas from disperse fluid inclusions at high working pressures and specific consumption of gas-liquid mixture by preventing ascending film flows on walls of separator chamber and phenomenon of spray mud from surface of separated liquid phase.
