摘要(Abstract)：

针对目前含油泥砂无害处理工艺流程繁琐、成本高昂的现状,基于旋流器内旋流场强湍动特性,将其应用于含油泥砂除油领域并展开室内可行性试验研究。通过微观分析得到油相在油泥砂中的4种存在状态:油泥中游离态油、颗粒间桥接油(絮团表面包覆油)、颗粒表面吸附油以及颗粒孔隙内微细油滴,并分别阐述了对应分离形式。采用轴流式DN50型旋流器开展室内可行性试验,结果表明:使用单级旋流器,在处理量4 m~3/h、溢流比12%、破乳剂浓度100 mg/L条件下,处理后油泥砂含油率可达0.5%;使用两级串联旋流器,在处理量4 m~3/h、一级溢流比12%、二级溢流比6%、破乳剂浓度100 mg/L条件下,原油回收率可达91.29%,处理后油泥砂含油率可达0.1%,低于直接排放标准值,表明旋流工艺能够实现油泥砂的高效分离、原油的高效回收和油泥砂的达标处置。
At present，the harmless treatment process of oil sludge is complicated and costly.Based on the strong turbulence characteristics of the swirl field in the cyclone，the swirl was applied to the oil removal field of oil sludge and the feasibility experiment was carried out in the laboratory.Four states of oil phase in oil sludge were obtained by microscopic analysis：Free oil in oil sludge，bridging oil between particles(oil coated on floc surface)，adsorbed oil on particle surface and fine oil droplets in particle pores.The corresponding separation forms were described respectively.Laboratory feasibility experiments were carried out with DN50 type axial cyclone.The results show that the oil content of oil sludge can reach 0.5% when the treatment capacity is4 m~3/h，overflow ratio is 12% and concentration of demulsifier is 100 mg/L.Using two-stage series cyclones，the recovery rate of crude oil can reach 91.29% at the treatment capacity of 4 m~3/h，the primary overflow ratio of 12%，the secondary overflow ratio of 6%，and the concentration of demulsifier is 100 mg/L.The oil content of the treated oil sludge can reach 0.1%，which is lower than the standard value of direct discharge.The results show that the cyclone process can achieve efficient separation of oil sludge，efficient recovery of crude oil and standard disposal of oil sludge.
