摘要

为研究喷雾荷电振弦栅除尘器外设条件对除尘效率的影响,在振弦栅过滤系统最优配置的基础上,以除尘效率η为参照结果,选定入口粉尘浓度(Q)、风速(V)、喷雾水压(P)和电晕电压(E)四个外设影响因素进行单因素试验.运用SPSS软件分析研究外设因素与除尘效率之间的关系,结果表明:四因素综合作用时电晕电压、喷雾水压、入口平均粉尘浓度对除尘效率显著,电场风速不显著;利用SPSS软件的相关及回归方法分析试验数据,建立了试验四因素综合效应的除尘效率经验公式,效验表明该公式可靠.%This paper is to study the effect of the external condition on the dust removal efficiency of dust collector with spray charged vibrating grid. Based on the optimal allocation of the vibrating grid filtration system and taking the dust removal efficiency (η) as the reference result, four single tests are carried out, which are about the four external influencing factors: the entrance dustbearing concentration (Q), the wind speed (V), the spray water pressure(P) and the corona voltage(E). Using SPSS software to analyze the relationship between the external factors and dust removal efficiency, the researchers found that,with the comprehensive effect of the four factors, corona voltage, spray water pressure and the average entrance dustbearing concentration are significant to the dust removal efficiency, but the wind speed of electric field is not; Based on the data from the correlation and regression method of SPSS software, the empirical formula of dust removal efficiency relating to the comprehensive action of the four factors was established, and the efficacy showed that the formula was reliable.
