CFD Simulation of Solid-Liquid Suspension in Concentrate Received Stirred Tank
Solid-liquid suspension uniformity in concentrate received stirred tank is the key factor to determine the stability of downstream operation.In the present work,the solid-liquid suspension process and the effect of stirred speed were simulated by computational fluid dynamics using multiple reference frame method and mixture multiphase flow model.The simulated results showed that the axial flow capacity of current three-layer agitator was not enough,leading to solid deposition.Besides,the non-uniform suspension condition was not be solved by increasing the stirred speed.Furthermore,an optimized two-layer axial agitator with strong axial flow capacity was proposed,which could satisfy efficient bulk circulation in the tank and relatively uniform distribution of solids.
