油-水分离用水力旋流器试验

用有机玻璃制成的试验用油-水分离水力旋流器（主直径D＝0．038m）是由旋流腔、大锥体段、小锥体段与圆柱段组成。在自行设计的试验台上进行了水力旋流器试验，试验用污水是用自来水加原油配制而成。入口污水含油浓度为400ppm，入口污水流量为1～6m3／h。试验结果表明，水力旋流器的压力降随入口流量的增加而增加（当入口流量增加到3m3／h，分离效率也随流量的增加而增加），当人口流量增加到5m3／h时，压力降达0．170MPa（分离效率可高达97％）；当分流比在2％～5％时，出口净化水的含油浓度可降至15ppm。

Oil-Water Separateing Hydraulic Cyclone Test

The test device is made of organic glass. Test result shows that the pressure of the cyclone increases as the inlet flow increases;when the inlet flow increases to 3m3/h,the separating efficiency increases as the flow increases. when the inlet flow increases to 5m3/h, the pressure drop reaches to 0. 170 MPa and separting efficiency gets to 97%,When divide flow ratio at 2% ~5 %,the density of oil cut in outlet treated water can be decreased to 15 ppm.
