含油污水除油用旋流器的研究

为提高含油污水的油水分离效率 ,用油水混合物作为试验物料 ,通过析因试验 ,研究了旋流器用于含油污水除油的分离性能。探讨了溢流分率、溢流口直径、进料浓度、入口直径、尾管长度、进料流量及温度等对旋流器分离性能的影响。结果表明 ,上述参数均存在最佳结构尺寸和操作条件。在压力降为 0 3～ 0 5MPa时 ,旋流器的油水分离效率可达 99% ,即可将含油污水的含油量从 1 0 0 0ppm降到 1 0ppm。所得结果可用于指导含油污水除油用旋流器的设计和操作

An investigation into hydrocyclones for deoiling of waste water

The separation of oil from water with hydrocyclones has been systematically investigated through factorial experiments. The influences of the inlet diameter, overflow diameter, underflow extension pipe length, split ratio, feed flowrate and temperature on the separation performance are analyzed. The results show that a wide inlet and overflow outlet and a long underflow extension length are preferable. The investigation results could be used as a guidence to the design and operation of deoiling hydrocyclones.
