基于CFD的水力旋流器并联公共液斗结构研究

Study on flow rate of parallel common liquid bucket of hydrocyclone based on CFD

为解决并联水力旋流器分离效率下降的问题,设计了水力旋流器并联新式公共液斗。对于液斗底流口直径的大小,设计了8,12,16 mm三种不同结构,应用CFD技术分析比较了三种不同结构的流场稳定性。在流量相同的情况下,速度分布的对称性随着底流口增大而变差;而分析相同流量下不同结构的湍流强度,在不同入口流速下,12 mm结构的湍流强度平均值要小于16 mm与8 mm。

In order to solve the problem of decreasing separation efficiency of parallel hydrocyclones,a new bin structure of parallel hydrocyclones is designed.For the diameter of the underflow port of the bin structure,three different structures of 8 mm,12 mm and 16 mm are designed,and the flow field stability for the three structures is analyzed and compared with CFD.Under the same flow rate,the symmetry of velocity distribution becomes worse with the increase of underflow port;and the average turbulence intensity of 12 mm structure is less than 16 mm and 8 mm under different inlet velocities.
