The Key Parameter Simulation And Optimization Of A Cyclone

Cyclone separator has many advantages,such as simple structure, low-cost, lowenergy consumption, high temperature resistant. So it has been widely applied inpetrochemical, pharmaceutical production, power, environmental protection and theother industrial fields. However, because of lacked in economy and technology(especially in software), as well as the moving raw of internal flow field in cycloneseparator and the complex separation mechanism of multiphase flow. Its designed forstructure size was indicated half or the whole experience design, separation efficiency isnot high, so the range of application had been limited. Many structural parameters haveeffects on the dust removal efficiency, such as the cone angle, the insertion depth ofexhaust pipe, the entrance angle and the inlet velocity. This paper takes the cycloneseparator for oil-water separation in petroleum development as the main research object,it’s based on the finite element theory, Gambit, Fluent, Matlab and other relatedsoftwares, and the discrete phase particle motion model in the continuous flow. A seriesof simulation and optimization have been created on the relationship between four keyparameters and separation efficiency, then drew a conclusion: if the diameter of theparticles in the air is greater than2μm, the cone angle is12.36°, the insertion depth ofexhaust pipe is54.56mm, the entrance angle is37.16°, the inlet velocity is35m/s, theseparation efficiency can reach above99.9%in theory; At the same time, for the smallparticles which particle size under1.5μm, increase the entry angle or add the inletvelocity both can improve the separation efficiency. In this paper, the researchachievements has obvious enlightening significance and high practical value in designand application of cyclone separator.
