摘要
在分析水力旋流器基本组成与工作原理的基础上,采用计算流体力学(CFD)技术进行了水力旋流器的仿真模拟,分析了分流比、进口体积分数及溢流管壁厚对水力旋流器分离性能产生的影响。结果表明:分离性能随着分流比的升高而升高,但其升高的幅度由具体旋流器结构而定;随着体积分数的增加,旋流器对0.07～0.10mm粒径的分离效率呈简单的单调下降趋势;在相同操作条件下,旋流器溢流管壁厚的增加可以使分离效率提高,能耗降低。
Based on the analysis of basic makeup of hydrocyclone and working principle, the numerical Fluid mechanics was used to simulate real hydrocyclone, analyzing the effecting of diversion ratio, incoming concentration, and overflow pipe thickness to separation performance. The result showed that the separation was increased as the diversion ratio was increased,the increasing limit depending on its structure. As the concentration increased the separation effectiveness tended to decreasing with the particle diameter ranging from 0.07 to 0.10ram. at the same operation condition, to increase the thickness of overflow tube could increase separation efficiency with energy reduced.
