W底流口旋流器分离性能的数值模拟与试验研究
Numerical Simulation and Experimental Research on Separation Performance of a Hydrocyclone with W Underflow Pipe
摘要
Abstract
with respect to the problem of low underflow concentration and high content of fine particles with a traditional hydrocyclone during the construction of tailing dam,a hydrocyclone with W underflow pipe was proposed. The separation performance of a φ50 mm hydrocyclone was compared and analyzed through numerical simulation and test when equipped with W underflow pipe and conventional underflow pipe. The simulation results show that,for the hydrocyclone with"W"underflow pipe,the axial, tangential and radial velocities of the fluid all become smaller.The centrifugal force decreases and the residence time increases, which are beneficial for increasing the underflow concentration and reducing content of the fine particles.The test results show that the concentration increases from 62.4% to 64.28%,and the content of -20 μm particles decreases from 20.66% to 17.47%.关键词
