摘　　要：随着中国城市化和工业化的快速发展,粉尘污染问题日益突出。通过对喷雾降尘对旋式轴流风机的结构参数即一级叶轮叶片数、二级叶轮叶片数和导流叶个数进行单因素实验,将风机射程、流量及全压效率等作为评价指标,获得优化方案并仿真验证。研究表明:通过单因素分析,确定各结构参数的优选数值分别为一级叶轮叶片数为9,11,13,二级叶轮叶片数为8,10,12,导流叶个数为4,5,6;通过单因素实验及优化选定,确定优化方案为一二级叶轮叶片数分别为13,12,导流叶个数为6,优化方案较初始模型在射程提高了5.90%,流量提高了69.64%,全压效率提高到70.88%。With the rapid development of urbanization and industrialization in China,the problem of dust pollution has become increasingly prominent.Through the single factor experiment on the structure parameters of the atomized dust-dropping antiswirl axial fan,namely the number of first-stage impeller blades,the number of second-stage impeller blades and the number of guiding blades,the fan range,flow rate and total pressure efficiency are taken as evaluation indexes,and the optimization scheme is obtained and verified by simulation.The results show that the optimal values of each structural parameter are determined by single factor analysis:the number of first-stage impeller blades is 9,11,13,the number of second-stage impeller blades is 8,10,12,and the number of guiding blades is 4,5,6.Through the single factor experiment and optimization selection,the optimization scheme is determined that the number of first-stage and second-stage impeller blades is 13 and 12,respectively,and the number of diversion blades is 6.Compared with the initial model,the optimization scheme increases the range by 5.90%,the flow rate by 69.64%,and the total pressure efficiency by 70.88%.
