摘　　要：采用实验测量方法对荷电细水雾空气净化技术的机理进行研究.将荷电细水雾空净技术的作用机制归纳为直接净化和间接净化.研究获得直接净化机制的作用效果与时间的关系,给出综合净化机制作用下的净化效果和自然沉降情况下污染物的衰减状况,得出各净化机制的单独作用效果.随着室内相对湿度的增加,直接净化机制的作用效果显著提高,而自然沉降的作用效果始终很小.Experimental study of air purification technology by charged droplets has been carried out. The purification process could be divided into direct process and indirect process based on purification mechanisms. A mass conservation equation was proposed to establish the relationship between the purification effect of direct process and the processing time. The data showed the purification effect under the action of combined （direct and indirect） processes, and natural sedimentation was obtained by experimental measurements. The results showed the ratios for these purification mechanisms. As a result, the purification effect of direct process would increase with the relative humidity. Meanwhile, the effect of natural sedimentation has always a small proportion.
