Design of dedusting mechanism of cotton seed polishingmachine
[Abstract] Cyclone separator is an important gas—solid separation equipment,which has many advantages,such as simple structure,compact equipment,easy to manufacture,relatively low-cost and SO on.So it has been widely applied in the mining,chemical industry,energy source,environmental、protection,metallurgy,building materials and the other industrial fields.However,because of unreasonable structure design and size matching factors,which restrict the efficiency improving,besides it wastes more energy consumption.At present,with the continuous growth of the national economy and the energy—saving reduction strategy proposed timely,people urgently need to research a new type cyclone separator that has much higher separation efficiency and lower consumption.Therefore,in view of the unperfect separation model and the weak prevalence of the traditional design method.In addition,people can’t understand accurately the separation theories of cyclone separator.Using numerical simulation and optimal design combination of research methods,first of al l,the thesis constructs an optimal mathematics model based on the classic Leith—Licht boundary layer separation theory,and then,based on the results of 3D flow field numerical simulation,prove the rationality of the size match and the feasibility of the design optimization and propose a universal design method for the future provision of cyclone separator.
