VORTEX SYSTEM FOR SEPARATING PARTICLES FROM A LIQUID STREAM

摘要

A vortex system for separating particles of varied size and density from a liquid stream. A particle bearing liquid is introduced tangentially into one end of an elongated cylindrical chamber through an inlet (13) to form a rotating liquid vortex therein. An impeller (18) at one end of the chamber reinforces the vortex flow. A series of tangentially oriented jets (21) introducing a gas further increases the vortex rotational flow. The vortex produces a heavy particle rich outer region, a gas and light particle rich axial region and a cleaned liquid annular region therebetween. The cleaned liquid flows out of the chamber through an outlet (30) at the chamber end opposite the end at which the particle bearing liquid is introduced. The heavy particles in the outer region are removed through outlet (24) and the gas and light particles in the axial region are removed through outlet (26).
