摘　　要：除油旋流器是一种离心分离设备,油滴粒径沿旋流器轴向的变化关系到旋流器的分离效率。通过研究进口平均粒径与分离效率的关系;不同流量时旋流器各部位的平均粒径;分流比与旋流器各取样部位平均粒径的关系;进口平均粒径与旋流器各结构段分离效率的关系,得出结论:（1）分流比对旋流器边壁的平均粒径影响不大;（2）在正常分离条件下沿旋流器的轴向各边壁油滴的平均粒径逐渐减小,旋流器的各结构段均有一定的分离能力;（3）旋流器的大、小锥段的分离效率随进口平均粒径的增大而增加,直管段的分离效率基本不随进口平均粒径的变化而变化。Oil separating cyclone is a centrifugal separating device. The separating efficiency of the cyclone is related to the changes of oil droplets' diameter along the axial line. The factors influencing separating efficiency, such as average inlet droplets' diameter, split ratio and so on, are researched, and conclusions are obtained: (1) the split ratio influences faintly on the average diameter of the droplets on the sidewall of the cyclone; (2) under common conditions, the diameter of the droplets on the circular wall of the cyclone declines gradually;(3) the separating efficiency of two cone-shaped segments increases with average droplets' diameter, whereas the separating efficiency of straight pipe doesn't vary with them.
