Abstract

Abstract

In order to improve the leaching rate of vanadium and understand the liquid flow and solid distribution in the mechanical stirring tank for hydrometallurgical vanadium extraction, the software Fluent was used to establish the Euler-Euler model of multi-phase flow and the standard k-ε turbulence model, by dealing with the calculation area in the stirring tank via multi-reference system method based on the theory of computational fluid dynamics. The influences of stirring speed v, the height of blade from the bottom L and the perforated baffle on the flow field distribution in the stirring tank were investigated. The results show that the liquid phase velocity in the stirring tank gradually increases first and then basically stabilizes with the increase of stirring velocity v. Based on the influence of the height of the blade from the bottom L on the liquid velocity distribution, the most suitable value was determined at L=0.4D₁, where D₁ refers to the blade diameter. The perforated baffle is helpful to eliminate the vortex in the flow field and improve the flow field distribution.
