摘　　要：为提高KJS-400型对旋风机的除尘效率,通过对旋风机的一、二级叶轮轴向距离、输入压力及不同叶片形式进行单因素实验。为了方便更直观地观察改变不同参数对风机处理风量产生的影响,并获得优化方案并仿真验证,将体积流率作为评价指标。体积流率越大,证明单位时间内风机处理的风量越多。利用ANSYS中的Fluent模块对风机运转方式以及内外流场进行仿真,得到风机内流场的初始流动状态和进风量。再对有影响的参数采用控制变量法进行改进调试,利用单因素实验和正交实验确定KJS-400型对旋风机的最佳设计参数,从而提高对旋风机的除尘效率。In order to improve the dust removal efficiency of KJS-400 countercyclone fan,a one-factor experiment was conducted through the axial distance of the primary and secondary impellers,input pressure and different blade forms of countercyclone fan.In order to facilitate a more intuitive observation of the impact of changing different parameters on the air volume handled by the fan,and to obtain the optimization scheme and simulation verification,the volumetric flow rate is used as an evaluation index.The larger the volumetric flow rate is,the more air volume the fan handles per unit time is proved.Using the Fluent module in ANSYS to simulate the fan operation mode and the internal and external flow fields,the initial flow state and air intake in the flow field of the fan are obtained.Then the influential parameters are improved and debugged using the control variable method,and the optimal design parameters of the KJS-400 countercyclone fan are determined using single-factor and orthogonal experiments,so as to improve the dust removal efficiency of the countercyclone fan.
