CYCLONE FILTER Russian patent published in 1996 - IPC

FIELD: devices for separation of nonhomogeneous media. SUBSTANCE: starting liquid enters helical passage 3 via inlet passage 6 where it is separated into heavy and light phases under action of centrifugal inertial force. Particles of heavy phase are discharged through branch pipe 10 and cleaned liquid is discharged through passage 9. Helical passage 3 has trapezoidal section, thus increasing tangential velocity in zones of lesser passage areas and consequently enhancing efficiency of cleaning. EFFECT: enhanced efficiency of cleaning. 1 dwg
