摘　　要：为解决PM2. 5难以脱除的问题,设计并开展正交试验以研究水雾荷电特性及含尘气流风速对PM2. 5脱除效率的影响。采用线性回归分析方法处理数据,分析气液两相荷电水雾脱除PM2. 5的特性,建立PM2. 5脱除效率回归模型。结果表明:所建回归模型是有效的,应用回归模型可以预测PM2. 5脱除效率;当荷电电压x1为12 kV、电极间距为15 mm、电极环直径x3为60 mm、气液比x4为1. 5、喷嘴直径x5为0. 6 mm、含尘气流风速x6为4 m/s时,PM2. 5脱除效率最优值为97. 26%;PM2. 5脱除效率与x1、x2、x4正相关,与x3、x5、x6负相关,因素近重要程度排序为x1>x6>x4>x5>x3>x2。To solve the problem of difficult removal of PM2. 5,an orthogonal experiment was designed to effects of charge-characteristics of water mist and dust-laden air velocity on efficiency of PM2. 5 removal were studied by carrying out orthogonal experiments. Experimental data were processed by the analysis method of linear regression. A regression model was built for PM2. 5 removal efficiency. The results show that the regression model is an effective one and can be used to predict the efficiency of PM2. 5 removal,that when the charge voltage( x1) is 12 kV,electrodes distance( x2) is 15 mm,electrode ring diameter( x3) is 60 mm,gas-liquid ratio( x4) is 1.5,nozzle diameter( x5) is 0.6 mm,dusty airflow velocity( x6) is 4 m/s,the optimal value of PM2. 5 removal efficiency is 97. 26%,that there is a positive correlation between factors-x1,x2,x4 and PM2. 5 removal efficiency,and a negative correlation between factors-x3,x5,x6 and PM2. 5 removal efficiency,and that the importance ranking of factors is x1>x6>x4>x5>x3>x2.
