Abstract
A centrifugal separator includes a cylindrical bowl, a core tube assembly, and an annular piston disposed around the core tube assembly and inside the inner surface of the bowl. Feed liquid is injected down the core tube assembly into the lower portion of the bowl, raising the annular piston. During a separation mode, the bowl rotates at high speed, separating solids from the feed liquid to accumulate along the inner surface of the bowl, while collecting clarified centrate as it exits the top of the bowl and through the core tube assembly. Following solids accumulation, bowl rotation is stopped and residual liquid is pumped from the bowl. In a solids discharge mode, the annular piston is urged downward along a vertical axis in response to compressed gas. The downward movement of the piston forces accumulated solids from the bowl via an opening in the lower end thereof.
