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(shi)式電(dian)(dian)除塵器主要有兩種結(jie)構形式，一(yi)種是(shi)使用(yong)(yong)耐腐蝕(shi)導(dao)(dao)電(dian)(dian)材(cai)料(liao)(liao)(liao)（可以為導(dao)(dao)電(dian)(dian)性能優良的(de)的(de)非金屬材(cai)料(liao)(liao)(liao)或具有耐腐蝕(shi)特性的(de)金屬材(cai)料(liao)(liao)(liao)）做(zuo)集塵極，另(ling)一(yi)種是(shi)用(yong)(yong)通過噴水(shui)(shui)或溢流水(shui)(shui)形成導(dao)(dao)電(dian)(dian)水(shui)(shui)膜，利用(yong)(yong)不導(dao)(dao)電(dian)(dian)的(de)非金屬材(cai)料(liao)(liao)(liao)做(zuo)集塵極。
