Abstract

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. © 2019 China Safety Science Journal.
