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。

濕式電除塵(chen)器主(zhu)要有(you)兩種(zhong)結(jie)構形(xing)(xing)式，一種(zhong)是使用(yong)耐腐(fu)蝕導電材料(liao)（可以為導電性能(neng)優良(liang)的(de)的(de)非(fei)金屬材料(liao)或具(ju)有(you)耐腐(fu)蝕特性的(de)金屬材料(liao)）做集塵(chen)極(ji)，另一種(zhong)是用(yong)通過(guo)噴水(shui)或溢流(liu)水(shui)形(xing)(xing)成導電水(shui)膜，利用(yong)不導電的(de)非(fei)金屬材料(liao)做集塵(chen)極(ji)。
