Background
The oil sewage contains oil substances such as natural petroleum, petroleum products, tar and fractionated substances thereof and solid particles such as sludge, rust, sand and stone. Three-phase separation is required before treatment. At present, gravity settling tanks are mainly used for three-phase separators. The gravity settling type equipment is large in size, assemblies such as a weir plate are usually arranged inside the gravity settling type equipment, and the structure is complex. In addition, since the separation process is performed by gravity, the process has disadvantages such as long process time, discontinuous work, and large floor space. However, it is difficult to separate oil from water. The cyclone has been used in China as a separation device, the separation principle of the three-phase separator is that centrifugal separation is performed by using density difference between media, and the larger the density difference is, the better the separation effect is. The cyclone can separate oil, water and slag for reuse. But due to the oscillating centre of rotation of the cyclone, the already separated particles, water and oil will again mix in the central zone, resulting in a reduced quality of the separated oil. Therefore, how to improve the structure of the cyclone and improve the separation effect of the cyclone becomes a problem to be solved urgently in the oil sewage treatment industry and the practice of the related industry.
