一、引言随着我国电力工业的发展,火力发电厂越来越多地采用电除尘器作为消烟除尘的重要设备.电晕电场在除尘过程中起着关键作用,因为它既影响着所要捕集的尘艺的荷电,也影响着作用在已荷电的尘粒上力的大小.电除尘器的电晕电场是由在两极间施加了高电压和两极间的空域中存在着由离子和荷电粒子构成的空间电荷所形成的. 电除尘器的Deutch除尘效率公式为:
I. INTRODUCTION With the development of power industry in our country, ESPs are increasingly used as an important equipment for smoke and dust removal.The corona electric field plays a key role in the dust removal process because it affects both the desired Set the dust of the charge, but also affect the role of the dust particles have been charged in the size of the electrostatic precipitator corona electric field is imposed by the high voltage between the two poles and the airspace exists between the ions And charged particles formed by the space charge formed by the electrostatic precipitator Deutch dust removal efficiency formula:
