Performance Calculation of a Continuous Flow Filter Centrifuge with an Auger for Sludge Discharge

Abstract

The process of separation of a liquid + solid suspension in the rotor of an auger filter centrifuge (AFC) with an auger for sludge discharge is simulated. Taking into account the kinetic features of the sedimentation process of the solid phase in a stream, the key performance indicators of device operation were formulated according to separation by size and the clarification coefficient of the suspension. Based on a specific example of AFC-type equipment, the results of a numerical simulation separation of powdery substances are given for varied concentration of the solid phase, liquid viscosity, and angular velocity of the rotor.
