除油旋流器入口流量与基本性能的关系研究

对除油旋流器边壁的油滴粒径变化、旋流器的分离效率以及压力降与入口流量之间的关系进行了研究。结果表明 ,当入口流量达到一定程度时 ,旋流器边壁的平均粒径随入口流量的增加而降低 ,分离效率随入口流量的增加而增加。整个旋流器以及旋流器各段的压力降均与入口流量成指数关系 ,都随入口流量的增加而增加。在旋流器的压力损失中 ,进口、旋流腔及大锥段所占比例最大 ,且基本不随入口流量的变化而变化 ;小锥段次之 ,并随入口流量的增大而增大 ;直管段的压力损失所占的比例最小 ,它随入口流量的增大而不断降低。

Research on the Relation Between the Flowrate and the Fundamental Performance of a De-Oiling Hydrocyclone

Researches were performed of the relation between the size changes of oil drops on the wall,the separation efficiencyt,the pressure drop and the inlet flowrate of the de oiling hydrocyclones.The result shows that the average oil drop size on the wall of the hydrocyclone decreased with the increase of the flowrate when the flowrate reached a certain value, the separation efficiency rose with the increase of the flowrate, the pressure drops in the whole hydrocyclone and its various sections had an index relation to the flowrate, and they rose with the increase of the flowrate. The pressure loss proportion in the inlet, swirling chamber, and big cone section of the swirler were much more than those in all other sections,and these pressure losses varied hardly with the change of the flowrate; the pressure loss proportion in the small cone section was the second, the pressure in the small cone section rose with the increase of the flowrate; the pressure loss proportion in the straight tube section was the least, which continuously decreased with the increase of the flowrate.
