Authors:Li Yunfeng, Li Yuting

Abstract


With the development of science and technology, the increasingly frequent offshore oil exploration, exploitation and transportation activities make the marine environmental pollution accidents happen frequently, which has a bad impact on the marine ecological environment. This paper presents a device for treating oil slick on the surface of ocean and a numerical simulation method for oil-water separation. Through the emergency treatment of oil-water separation hydrocyclone to deal with the floating oil pollution on the ocean surface, the oil-water separation performance of the device is simulated by the calculation method of the optimal control parameters of oil-water separation based on the mathematical model of flow field. The simulation results show that the hydrocyclone has a good separation performance when the split ratio is 4.1%, the inlet pressure is 0.15 MPa, the overflow pipe diameter is 3 mm, the oil drop size is 101, and the Dazhui angle is 27°. Under this condition, the method can be used as a reference method for the treatment of oil-water spills in the ocean, and it has a certain application value.
