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)電除塵器主要有兩種(zhong)結構形式(shi)，一種(zhong)是使用耐腐蝕導電材(cai)料(liao)（可以為導電性能(neng)優(you)良的(de)(de)的(de)(de)非金屬材(cai)料(liao)或具有耐腐蝕特性的(de)(de)金屬材(cai)料(liao)）做集(ji)塵極，另(ling)一種(zhong)是用通過噴水(shui)(shui)或溢流(liu)水(shui)(shui)形成導電水(shui)(shui)膜，利用不導電的(de)(de)非金屬材(cai)料(liao)做集(ji)塵極。
