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)(dian)除塵(chen)器主(zhu)要有(you)兩(liang)種(zhong)(zhong)結構形(xing)式，一(yi)種(zhong)(zhong)是使(shi)用(yong)耐腐蝕(shi)導(dao)(dao)電(dian)(dian)(dian)材(cai)料(liao)(liao)（可以為導(dao)(dao)電(dian)(dian)(dian)性能(neng)優良的(de)的(de)非金屬(shu)材(cai)料(liao)(liao)或具(ju)有(you)耐腐蝕(shi)特性的(de)金屬(shu)材(cai)料(liao)(liao)）做集塵(chen)極(ji)，另(ling)一(yi)種(zhong)(zhong)是用(yong)通過噴水(shui)或溢(yi)流(liu)水(shui)形(xing)成導(dao)(dao)電(dian)(dian)(dian)水(shui)膜(mo)，利用(yong)不(bu)導(dao)(dao)電(dian)(dian)(dian)的(de)非金屬(shu)材(cai)料(liao)(liao)做集塵(chen)極(ji)。
