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)除塵器主要有兩種結構(gou)形(xing)式(shi)，一(yi)種是使用耐(nai)腐(fu)蝕導(dao)電(dian)材料(liao)（可以為導(dao)電(dian)性能(neng)優(you)良的(de)的(de)非金(jin)(jin)屬材料(liao)或具有耐(nai)腐(fu)蝕特性的(de)金(jin)(jin)屬材料(liao)）做集(ji)(ji)塵極，另一(yi)種是用通(tong)過噴(pen)水或溢流水形(xing)成導(dao)電(dian)水膜(mo)，利(li)用不導(dao)電(dian)的(de)非金(jin)(jin)屬材料(liao)做集(ji)(ji)塵極。
