| 实验采用新型高效水雾荷电振弦栅除尘方法，以过流速度v、水雾荷质比β及芒刺数n 3个除尘效率影响因素为研究对象。在喷嘴雾化参数及振弦栅参数一定时，通过单因素实验得到除尘效率与过流速度呈二次负相关，与水雾荷质比呈二次负相关，与芒刺数呈一次正相关；利用SPSS软件对实验数据处理后得到各因素对除尘效率的权重系数为过流速度0.885、水雾荷质比0.094、芒刺数0.021，各因素对除尘效率的影响从高到低依次为过流速度＞水雾荷质比＞芒刺数；根据单因素相关性及其权重系数,提出三因素综合除尘效率理论回归方程为η=94.479-0.885v+0.094β+0.021n。 |

| A new and high performance method for dust removal using charged water mist vibrating grid was adopted in this experiment. Three influence factors were selected as the study objects, which were flow velocity(v),charge to mass ratio of water mist(β) and the number of barb(n). Single factor experiment results showed that when the atomizing parameter of nozzle and vibrating grid parameter were constant，the dust removal efficiency was negatively correlated with the squared flow velocity, the same as the charge to mass ratio of water mist, and was positively correlated with the number of barb. Using the SPSS software to deal with the experimental data, the weight coefficient of dust removal efficiency for each factor were as follows: the flow velocity was 0.885, the charge to mass ratio of water mist was 0.094, and the number of barb was 0.021. These impact factors on removal efficiency ranged in descending order as flow velocity, charge to mass ratio of water mist and barb number. Based on the experimental results of single factor correlation and the weight coefficient, a theoretical regression equation of three factors comprehensive dust removal efficiency was put forward, that is η=94.479-0.885v+0.094β+0.021n. |
