粉体内空气隙局部电场的研究

A Study of the Local Electric Field Inside a Dust Body

本文通过对粉尘粒子堆积模型的合理假设,运用电介质极化理论,详细研究了沉积粉尘粒子在高电场作用下的极化过程,建立了粉尘层与收尘极板间的平均电场和粉尘层内部空气隙局部电场的理论关系式.实验表明,这一关系式在电收尘的范围内与实测值很相符.

The polarization procedure of precipitated dust particles under the action of high electric field is investigated and viewed from the theory of electric polarization.Based on the hypothesis for the accumulative model of particles , the theoretical relationship is established between the average electric field across the dust layer and the local electric field inside the dust layer between particles. The experimental results show that calculations worked out are in agreement with actual measurements within the range of electrostatic precipitation .
