摘要
为了提高旋流器优化参数的准确性,得到其在结构优化中的最优解,以一种新型复合旋流器为研究对象,基于相关性的单因素分析寻优法,以相关性分析的结果来指导优化范围的选取,提高其结构参数优化范围的准确性。结合响应面优化方法,以分离效率为优化目标,确定旋流器的最优结构参数,建立了分离效率和结构参数之间的回归模型。结果表明:不同的结构参数和各性能指标之间的显著关系并不相同,根据相关性分析的结果确定各结构的优化范围为:上锥角为0°~4°,下锥角为8°~12°,底流口直径为12~16 mm;响应面优化得到旋流器最优结构为:上锥角为2.565°,下锥角为11.719°,底流口直径为12.889 mm,在本组参数下旋流器固体分离效率达到了99.945%,气体分离效率达到了93.807%。为旋流器的结构优化提供了一种新方法。
To improve the accuracy of the optimization parameters of the cyclone and obtain the optimal solution in structure optimization,a new type of composite hydrocyclone was taken as the research object,the single factor analysis optimization method based on correlation analysis was used to guide the selection of optimization range and improve the accuracy of optimization range of structural parameters.Based on the response surface optimization method,the optimal structural parameters of the hydrocyclone were determined with the separation efficiency as the optimization objective,and the regression model between the separation efficiency and the structural parameters was obtained.The results show that the significant relationship between different structural parameters and each performance index is not the same.According to the results of correlation analysis,the optimal range of each structure is as follows.The upper cone angle is 0°~4°,the lower cone angle is 8°~12°,and the diameter of the bottom nozzle is 12~16 mm.The optimal structure of the cyclone obtained by response surface optimization is as follows:the upper cone angle is 2.565°,the lower cone angle is 11.719°,and the diameter of the bottom flow port is 12.889 mm.Under these parameters,the solid separation efficiency of the hydrocyclone reaches 99.945%,and the gas separation efficiency reaches 93.807%.It provides a new method to optimize the structure of hydrocyclones.
