Abstract


The research aims at the demonstration and mends of design on the new hydro cyclone and uses the multiphase to analysis and calculation the interior of the hydro cyclone flow, to optimize the result in order to improve the equipment.The hydro cyclone is a kind of browser and classificatory equipment. Because of its simply structure the hydro cyclone finds application in more and more industries. Now, the main research measure is experimentation with real situation according to single factor, which cost more and is inefficient and can’t match the industrial needs. This thesis use FLUENT and combine with a serious of theoretical to simulate the flow field of the hydro cyclone by selecting the proper mathematical model and defining the boundary condition exactly to improve the existing hydro cyclone in a reasonable way, according to the overflow of oil content, the entrance rate of the second phase and the size of operating parameters to analyze the separation performance of hydro cyclone with the changes of various parameters to find the efficiency of the model pattern, quantitative analysis of the hydro cyclone flow field various parameters and to identify improvements to its lack of points.In this paper, liquid-liquid hydro cyclone separation mechanism of the flow and in-depth exploration of hydro cyclone separators within the state and the turbulent flow field in the case of state made a description and calculation, according to divert the entire flow field efficiency and the turbulent energy loss to verify that the increase in steady flow tube to reduce the hydro cyclone flow field within the whole energy loss of the feasibility and practicality of the future for more in-depth research has laid a solid foundation.
