| 摘 要： | 在高压高频复合电场和过滤器联合作用对空气进行净化时,建立了可吸入气溶胶颗粒凝并的数学物理模型,得出了半值时间tH的表达式,同时,设计了一套试验装置对理论模型进行验证.研究结果表明,随着可吸入气溶胶颗粒初始浓度的增加,半值时间tH减少,气溶胶颗粒浓度减半所需的换气次数减少.与只有过滤器作用时的理论模型比较,高压高频复合电场和过滤器联合作用时的半值时间tH减少了,缩短了空气的净化时间.研究结果为工程设计提供了理论和试验基础. |

| Abstract: | A mathematical and physical model of the inhalable aerosol particles coagulation under the joint action of high voltage and high frequency complex electric fields work together with the filter is developed and solution of the half time tH is obtained.At the same time,a set of experimental device is built to verify the theoretical model.The results show that the half time tH drops while the initial concentration of the inhalable aerosol particles reduces and the air change rate required for halved concentration reduces with increasing initial concentration.Compared with the theoretical filter model,the half time tH is reduced nearly half when the high voltage and high frequency complex electric fields work together with the filter.The time of air purification is greatly shortened.The research provides the theoretical and experimental foundation for engineering design. |
