HYDROCYCLONE MODULE Russian patent published in 1994 - IPC

FIELD: purifying and separating fuel. SUBSTANCE: through inlet opening 2 opposite flow divider 4 in shell 1 initial working fluid is fed under pressure into annular intermediate spaces 7. Then the fluid is passed via tangential inlet ducts 8 disposed in two levels in cylindrical members 5 and enters the inner spaces of cylinder-conical bodies 6 to be set in rotation. The heavier particles held in the fluid are centrifuged out to the inner partitions of bodies 6 and discharged through pipes 10. In bodies 6 the rotating flows act on impeller 14 so that cylindrical pipes 12 are put into motion in bearings 16 and receive the purified flows which are withdrawn via drain 11 and discharge opening 3. Pipes 12 are provided with helical members which enable guiding directed concentrates flows introduced into bodies 6 through discharge openings 13. EFFECT: better quality of separating. 3 dwg
