Abstract

Hydrocyclone in which the underflow emerges from an annular opening with a diameter larger than that of the overflow, and in which the apex of the core surrounded by the annular opening consists of a vertically adjustable plug on the core axis. The plug is essentially streamlined w.r.t. the liquid flow in the hydrocyclone. The increase of the underflow diameter reduces turbulence and increases the collection efficiency. The plug can be used to close the core bottom for an exchange of collection tanks.
