Structure optimization of cyclone based on response surface method

XIONG Pan;YAN Shuguang;LIU Weiyin;College of Resource and Environmental Engineering, Wuhan University of Science and Technology;Hubei Key Laboratory for Efficient Utilization and Agglomeration of Metallurgic Mineral Resources;  
To optimize the separation efficiency and energy loss of the cyclone separator, the main structural parameters affecting the performance of the cyclone separator are determined. The response surface model and CFD numerical simulation are used to select the dust outlet diameter(Dd), exhaust port diameter(De), and inlet velocity(V), and the pressure drop and the total separation efficiency are used as the objective functions, and the three-factor optimization design analysis is performed. The results show that the diameter of the exhaust port has littleeffect on the pressure drop and the separation efficiency. The diameter and velocity of the exhaust port havesignificant effects on the pressure drop and the separation efficiency, and the interaction between the diameter ofthe exhaust port and the velocity is obvious. For the current 0.5—10 μm particle group, the optimal parameters areDe/D=0.35, Dd/D=0.37, V=12 m/s. Compared with the experimental structure, in the case of similar separationefficiency, the pressure drop is reduced by half, effectively reducing the energy consumption. The establishedresponse surface model can accurately represent the relationship between design variables and objective functions.Optimization design method based on response surface model can be effectively applied to structural optimization of cyclone separator. And different particle size requirements can use different structures for dust removal. To achieve the separation requirements of the premise, the structure of the minimum pressure drop is used. This study providesa favorable basis for the separation of 0.5—10 μm particle size structure.
