Numerical Simulation for Effect of Baffles on Settling Velocity of the Settler in Rare Earth Extraction Tank AITranslate
Abstract AITranslate
With a simplified model of the settler in industrial rare earth extraction tank as the research object,the flow field of the settler with baffles was numerically simulated by using a fluid simulation software of Fluent.The effects of baffle installation height on settling velocity of the settler were analyzed based on the thickness of dispersion band.The results show that either too high or too low baffle installation height is not conducive to the separation of two phases,and the best baffle installation height is 310 mm for 50 L extraction tank.The formation of dispersion band is microscopically analyzed by velocity vector diagrams,and the role that baffles play in the settler is explained from the aspect of liquid flow patterns to further verify the best baffle installation height.
