双排料型旋流器数值模拟和试验研究
Numerical Simulation and Experimental Study on Dual Output Hydrocyclone
摘要
Abstract
A Φ50mm dual output type hydrocyclone is to be put forward and designed,aiming at solving the problem of single output type hydrocyclone underflow easy to clip fine particles,Using the fluid analysis software FLUENT to simulate the internal particles distribution and comparative analysis of the single output type and dual output type hydrocyclone,then,the related experiments have been carried out.Through simulation analysis,we find near the bottom of dual output cyclone's,fine particle volume fraction is decreased obviously,and it has been reduced by underflow discharge.Use Quartz sand laboratory test results show that the Φ50mm dual output type hydrocyclone's-5μm particles has been reduced 55.7%,The sharpness index has been increased 64.7%,So the underflow fine clipping phenomenon has been improved,the separation accuracy of the hyrocyclone is Increased.关键词
