【技术实现步骤摘要】
一种电袋复合除尘器
本专利技术涉及一种工业灰尘处理装置,尤其涉及一种电袋复合除尘器。
技术介绍
随着国民经济发展和城市化进程的加快,以煤炭为主的能源结构使得我国燃煤烟气的排放量不断增长,细颗粒物的污染日益严重。传统的除尘技术难以满足日益严格的排放要求,电除尘器尤其是湿式电除尘器作为烟气污染物的终端精处理装备,具有捕集烟气中细颗粒物和雾滴的功能,逐步在火力发电行业得到推广应用。湿式电除尘器脱除粉尘分为荷电、集尘、清灰三个步骤,其工作原理为:金属放电极在直流高电压的作用下,在其周围发生电离,由此而产生的电晕电流向集尘极流动,在流动过程中,如果碰到烟气中的尘粒或雾滴,则与之结合形成带电粒子,该粒子在电场中受到库仑力的作用而向集尘极运动,当运动到集尘极表面时,随连续水膜流出。
技术实现思路
