HYDRAULIC CYCLONE Russian patent published in 2003 - IPC

FIELD: separation of dispersion systems; chemical, oil-refining and oil industries. SUBSTANCE: proposed cyclone has cylindrical and taper housing which is provided with tangential inlet branch pipe, light phase discharge branch pipe and sand packing; housing is also provided with impeller. Inclination of leading edges of impeller blades coincides with inclination of trajectory of motion of heavy phase. Trailing edges of blades are directed over axial planes. During operation of hydraulic cyclone, negative pressure ingredient occurs in direction to light phase discharge branch pipe, thus intensifying motion of light phase towards branch pipe and excluding its penetration into sand packing. EFFECT: enhanced efficiency. 3 dwg
