ABSTRACT:
A centrifuge apparatus (10) for separating multi-phase fluid is disclosed. The centrifuge apparatus (10) includes a bowl-like structure (12) rotatably mounted in a housing (14) for rotation about a vertical axis. The centrifuge apparatus (10) further includes means for introducing multi-phase fluid into the bowl (12) and means for driving the bowl (12) at a predetermined rotation speed. A rotor assembly is coaxially mounted in the bowl (12) for rotation therewith to accelerate or impel the multi-phase fluid such that the fluid is separated into heavier phase fluid and lighter phase fluid with solid particles being collected on the inner surface of a bowl side wall portion (16).
A top wall member (18) of the bowl (12) defines axially directed openings (50) therein for discharging the heavier phase fluid. Discharge means positioned in the cylindrical side wall portion (16) extend radially into the interior of the bowl (12) for discharging the lighter phase fluid. The centrifuge apparatus (10) further includes purge means for dislodging solid particles accumulated on the cylindrical side wall portion (16). Drain means provided in the bowl (12), drains the fluid with resuspended particles from the bowl during the purge cycle.
