一、前言电收尘器中电暈电流的大小,是收尘电场强度的一种表示方法。而收尘电场强度的大小是和收尘效率密切相关的,所以提高电收尘器的电暈电流有助于提高收尘效率。众所周知,空运轉試車时电收尘器中的电暈电流有最大值,但通入含尘气体以后,即因单位气体体积 I. Introduction The size of the corona current in the electric precipitator is a way of expressing the electric field strength of the dust collector. The size of the electric field is closely related to the dust collection efficiency, so increasing the corona current of the electric precipitator helps to improve the dust collection efficiency. As we all know, when the empty running test electric precipitator corona current has a maximum, but after the introduction of dust gas, that is, due to the unit gas volume
