Oil-water Separator Cyclone Three-dimensional Numerical Simulation And Structural Optimization

The hydrocyclone for oil water separation used two-phase flow density is a poor market in centrifugal force will be scattered in a row to one's liking separated from the equipment. Its structure is simple, no relative motion components, separated efficient, affordable, easy operation and maintenance, and to meet the special requirements of different production, have so gotten increasingly extensive application in the fields such as mine, petroleum, environmental protection and chemical engineering. Recently, computer develop fast, making application CFD technology simulated flow out site to become possibility, more and more scholars have regarded using principle and method of compute hydrodynamics to simulate flow field of hydrocyclone.The article firstly simulates the internal flow field of hydrocyclone by using RSM model , basing on control volume method and applying PC-SIMPLE arithmetic. Distributing characteristic of velocity, pressure, kinetic energy and dissipation rate of turbulence in internal flow field of hydrocyclone were gained by numerical computation. Have investigated oil drop diameter and rate of flow and assign redundant civil servants to other jobs than change binary the influence from efficiency. Distribution law and separation characteristic of oil and water phases flow were obtained by computing. From oil phase thickness distributing chart of vertical section, it can be seen that the mainly parts of oil water separation is rotation flow pipe and cone segment. The conclusion is consistent with result of theory analyse. The established mathematical model achieved numerical simulation for distribution of oil phase slip velocity, which would help to analyse the progress of oil water separation in hydrocyclone. The mathematics model established has realized for oil appearance droplet radial slip speed distribution law imitate , which will help to hydrocyclone by oil separation process analysis.For checking up the result of numerical simulation, experiment study of separation character was completed about hydrocyclone. The result of simulation is basically in accordance with the experimental data. By comparing experiment data and result of numerical simulation. The simulation connection of flux and separate efficiency compared with the experimentation data and the relative error is within 8%.The simulation connection of distributary ratio and separate efficiency compared with the experimentation data and the relative error is within 10%.The two results prove the correctness of mathematical model and computing method.In flow into a decentralized market simulation of the flow of oil characteristics, and use of two mathematical models of turbulence in the flow of oil and processing of...
