In this paper, plaster cyclone for the study, the main use of the method of simulation experiments , the cyclone separation performance indicators . Imitate thermal power plant gypsum dewatering media and processes to build an experimental platform and scientific organization of the experimental method of orthogonal experiment , get a lot of data . According to the experimental data , analysis of the overflow tube diameter , wall thickness , depth length, the end of the flow tube diameter, length , operating pressure and inlet concentration changes alone gypsum cyclone separation performance indicators ; Secondly , the use of MATLAB software change the data of the combination of factors of the regression analysis , and reached the production capacity and the split ratio , the separation efficiency of the translation of the expression of the separation efficiency and the separation size indicators ; then analyzed the factors that affect the separation indicators , according to the model , and the results are consistent with the univariate analysis , a clear causal relationship . Index optimization , combined with gypsum cyclone knowledge , theory , focusing on the underflow density regulation and reduce the short - circuit flow are discussed . By changing the dimensions and proportions of the overflow tube and the bottom of the flow tube , so that the underflow concentration control within the desired range ; swirler having a new overflow pipe and the column segment structure and design , to achieve the purpose of reducing short-circuit stream flows , thereby improving the cyclone performance. Comprehensive research results , new gypsum cyclone model and numerical simulation and simulation are two ways , the comparison of the internal flow field and separation performance of the original cyclone model and the improved model , key indicators , new cyclone is better than the original structure , initially confirmed the feasibility of the optimization program .
