Abstract

A novel thickener feedwell was developed based on the traditional feedwell. It was easy to reform and had a simple structure. The flow field of the novel thickener feedwell was researched by computational fluid dynamics. The distribution of path line, the solid volume fraction and the velocity distribution in the exit plane were studied. The novel thickener feedwell could cope with variations of the flow rate, dissipate the kinetic energy of the feed stream and provide a uniform discharge pattern. The direction in which suspensions flowing out of the feedwell had an angle with the radial direction. The time increased for the feed to reach the overflow weir, making high solid-liquid separation efficiency. The novel thickener feedwell could work without any power and had a number of applications.
