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(dian)(dian)除(chu)塵(chen)(chen)器(qi)主要(yao)有兩種(zhong)(zhong)結構形(xing)式，一種(zhong)(zhong)是(shi)使用耐腐蝕導電(dian)(dian)材(cai)料(liao)(liao)（可(ke)以為導電(dian)(dian)性能優(you)良的(de)(de)的(de)(de)非金(jin)屬材(cai)料(liao)(liao)或具有耐腐蝕特性的(de)(de)金(jin)屬材(cai)料(liao)(liao)）做集塵(chen)(chen)極(ji)，另一種(zhong)(zhong)是(shi)用通(tong)過(guo)噴水或溢流(liu)水形(xing)成導電(dian)(dian)水膜，利用不導電(dian)(dian)的(de)(de)非金(jin)屬材(cai)料(liao)(liao)做集塵(chen)(chen)極(ji)。
