依照水力旋流器组合化的发展趋势,提出了一种将两个水力旋流器进行串联的组合式水力旋流器结构,并对新结构开展实验研究,着重考察操作参数对组合式水力旋流器的性能影响,得到底流率、入口浓度和入口流量与分离效率和压力降的变化规律。

英文摘要：

According to the development trend of compound hydrocyclone,a combined structure of having two hydrocyclones cascaded was proposed and the experimental study on this new structure was implemented,including the operation parameter＇s effect on the combined hydrocyclone＇s performance so as to obtain the relationship among underflow rate,inlet concentration,inlet flow,separation efficiency and the pressure drop.
