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)除塵(chen)器(qi)主要(yao)有(you)兩種(zhong)(zhong)結構形式，一種(zhong)(zhong)是使用耐腐(fu)蝕導(dao)(dao)電(dian)(dian)材(cai)料（可(ke)以為導(dao)(dao)電(dian)(dian)性(xing)(xing)能優(you)良的(de)(de)的(de)(de)非金屬(shu)材(cai)料或(huo)具有(you)耐腐(fu)蝕特性(xing)(xing)的(de)(de)金屬(shu)材(cai)料）做(zuo)(zuo)集塵(chen)極，另一種(zhong)(zhong)是用通過噴水或(huo)溢(yi)流水形成(cheng)導(dao)(dao)電(dian)(dian)水膜，利用不導(dao)(dao)電(dian)(dian)的(de)(de)非金屬(shu)材(cai)料做(zuo)(zuo)集塵(chen)極。
