摘　　要：对分离效率与液相流速、油水比例和旋流器级数之间的关系进行了系统的实验研究．通过受力分析从理论上对细颗粒易受参数影响的原因进行了阐述,并根据量纲分析和实验数据得到了分离效率与Re数和St数之间的函数关系．在此基础上,对液固旋流器的现场应用提出了有价值的建议．Liquid/solid hydrocyclones are widely used in industry and their separation efficiency is an important parameter in evaluating the performance. In this study, the relationships between separation efficiency and liquid velocity, oil/water ratio, as well as stage number are investigated. The reason why particles of smallerdiameter more sensitive to the changes of parameters is explained through a force balance analysis. Moreover, the relationship between separation efficiency and Reynolds number, Stokes number is obtained based on dimensional analysis. Finally, some suggestions are made for the application of liquid/solid hydrocyclones.
