Progress in the Application of Internal Components in Cyclone Separator

The development and application of internal components are highly significant to improve the efficiency and reduce energy loss of industrial equipment. Cyclone separator is a kind of industrial equipment for gas solid separation. With the development of chemical processes, cyclone separator is required that it not only can improve separation efficiency but also can reduce pressure drop. In this review, the principle of cyclone separator was firstly introduced, and then mechanisms of both reducing pressure drop and improving separation efficiency were analyzed. Compared with structural optimization and other methods, the installation of internal components can save production costs and also can reduce the engineering work loads. In addition, this study summarized the mechanism of various internal components (eg., reducing pressure drop stick, guide vane and vortex stabilizing device, etc.) and flow problems they could solve. Without changing the structure size, internal components can restrain the interference of vortex in cyclone separator and improve the stability of the flow. Because of the above reasons, internal components not only can effectively reduce pressure drop, but also can improve separation efficiency. Furthermore, the development trend of internal components was also reviewed in the paper. It has been found that use of multiple internal components will be more popular and the development of new internal components will be more diverse, delicate, precise and simple. Above development not only can improve separation efficiency and reduce pressure drop, but also can satisfy all kinds of environmental protection and process requirements.
