濕式電除塵器是一種用來處理含微量粉塵和微顆粒的新除塵設備，主要用來除去含濕氣體中的塵、酸霧、水滴、氣溶膠、臭味、PM2.5等有害物質，是治理大氣粉塵污染的理想設備。

濕式電除塵器通常簡稱WESP，與干式電除塵器的除塵基本原理相同，要經歷荷電、收集和清灰三個階段。

濕式(shi)電(dian)(dian)除(chu)塵(chen)器(qi)主要有兩種結(jie)構形(xing)(xing)式(shi)，一(yi)種是(shi)使用(yong)耐腐蝕導(dao)電(dian)(dian)材(cai)料(liao)(liao)（可(ke)以為導(dao)電(dian)(dian)性(xing)能優良的(de)的(de)非金屬材(cai)料(liao)(liao)或具有耐腐蝕特性(xing)的(de)金屬材(cai)料(liao)(liao)）做(zuo)集塵(chen)極(ji)，另一(yi)種是(shi)用(yong)通(tong)過噴水(shui)或溢流水(shui)形(xing)(xing)成導(dao)電(dian)(dian)水(shui)膜，利(li)用(yong)不導(dao)電(dian)(dian)的(de)非金屬材(cai)料(liao)(liao)做(zuo)集塵(chen)極(ji)。
