以简化的工业生产稀土萃取槽澄清室模型为对象,运用Fluent流体仿真软件,对安装挡板的澄清室内流场进行数值模拟,并从分散带厚度的角度分析澄清室内挡板的安装高度对澄清室澄清速率的影响。模拟结果表明,挡板安装高度太高与太低均不利于两相分离,50L萃取槽最佳挡板安装高度为310mm;并通过速度矢量图从微观上分析了分散带的形成,从液流形态方面解释了挡板在澄清室内发挥的作用,进一步验证了最佳挡板安装高度。
In order to simplify the industrial production of rare earth extraction tank clarification chamber model, using Fluent fluid simulation software to simulate the flow field in the clarified chamber with baffle installed, and clarify the installation height of the interior baffle to clarify Effect of room clarification rate. The simulation results show that the baffle installation height is too high and too low are not conducive to the two-phase separation, 50L extraction tank baffle installation height of 310mm; and through the velocity vector diagram microscopically analyzed the dispersion zone formation, from the flow Morphology aspects of the role of the baffle in the clarification chamber to further verify the best baffle installation height.
