[Abstract]:Oil spill pollution control is one of the worldwide problems in marine environmental protection. Mechanical oil spill recovery technology can effectively remove oil spills from the sea and recover oil resources effectively, and the recovery process of oil spills will not cause secondary pollution. Therefore is the relatively ideal oil spill control means at present. However, at present, the development of machinery oil spill recovery technology is still not mature, and most of the products developed have some shortcomings, such as complex structure, low recovery efficiency, limited application environment and so on, which can not meet the requirements of oil spill recovery. On the basis of summing up the working mechanism and characteristics of various oil spill recovery technologies at home and abroad, this paper determines that the curved oil collector is the research object of this paper. The structure of the oil spill is optimized to get better recovery effect. For this reason, the main work of this paper is as follows: (1) by comparing and analyzing the working principle, advantages and disadvantages of various types of oil spill recovery devices, it is determined that the dynamic curved oil collector is the optimized object. The geometric model with different lifting angles is established with the optimum parameters of the angle at the outlet of the curved channel and the shape of the inlet channel. (2) using fluid medium as oil-water mixture, using MIXTURE mixture model of fluid simulation software FLUENT to simulate the flow of the inner mixture of the structural model, and to obtain the flow field characteristics of each model; The recovery efficiency of oil from oil-water mixture is analyzed with the angle of outlet. (3) then several different values are selected for the radius of the upper edge of the inlet runner, and the geometric model is established by the mesh generation software GAMBIT. The MIXTURE mixture model in the fluid simulation software FLUENT is used to simulate the flow of the mixture inside the structural model to obtain the trend of oil recovery efficiency.
