Modeling and Simulation Research About the Separation Process of a New Solid-liquid Hydrocyclone Separator

For some problems of the new solid- liquid hydrocyclone in actual operation, designing a new diversion cyclone separator which is of high separation efficiency. By analyzing the principle of the cyclone separator, fluid mechanics fundamental laws combined with cylindrical cyclone separator modeling, establishing mathematical modeling of solid-liquid diversion cyclone separator. Found the speed of the new cyclone separator feed inlet velocity by calculation and simulation, in order to further study the flow field structure of the cyclone separator, applying the FLUENT software combined with Eulerian multiphase analysis and RNG k-e turbulence modeling to simulate cyclone separator's flow field.Obtain the visualization result of the flow field pressure distribution, velocity distribution and the particle trajectories distribution. the result shows that the special structure of the deflector designed in the cyclone separator can effectively refine the degradation of circulation flow and improve the separation efficiency of the cyclone separator, provide the technical guidance and theoretical foundation for the cyclone separator can separate diameter of particles is around 5 um and more than that.
