摘要:
为了提高荷电水雾对微细粉尘的捕集效果,围绕液滴荷质比这一影响粉尘捕集效率的主要因素开展针对性研究。分析水雾荷电过程的路径图，提取影响液滴荷质比的独立因素，并根据不同因素对荷质比影响的显著性设计正交实验，采用多因素回归分析的方法对实验数据进行处理。研究结果表明：在因素水平范围内，应用预测模型得出荷质比的最优值为441.66 μc/kg，误差小于5%；荷质比与荷电电压、气相射流压力、电极间距呈正相关，与液相射流压力、电极环直径、喷嘴孔径呈负相关；实验结果得出的荷质比计算公式可以用来预测液滴的荷质比，为荷电效果的定量分析提供依据。
Abstract:
To improve the capture effect of charged water mist on the ultrafine dust, the targeted study was carried out on the charge mass ratio of the droplets, which is the main influence factor of the dust capture efficiency. The path diagram of the charging process of water mist was analyzed, and the independent factors that may affect the charge mass ratio of the droplets were extracted. The orthogonal experiments were designed according to the significance about the influence of different factors on the charge mass ratio, and the experimental data were processed by the method of multivariate regression analysis. The results showed that in the range of factors level, the optimum value of charge mass ratio calculated by the prediction model was 441.66 μc/kg with an error less than 5%. The charge mass ratio was positively correlated with the charge voltage, gas jet pressure and electrode spacing, and was negatively correlated with the liquid jet pressure, diameter of electrode ring and nozzle aperture. The calculation formula of charge mass ratio obtained by the experimental results can be used to predict the charge mass ratio of the droplets, and provide the basis for the quantitative analysis of the charge effect.
