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(shi)式電(dian)除塵(chen)(chen)器主要(yao)有兩種(zhong)結(jie)構形式，一種(zhong)是使用耐(nai)腐蝕導電(dian)材(cai)料（可以為導電(dian)性(xing)能優良的的非金屬材(cai)料或具(ju)有耐(nai)腐蝕特性(xing)的金屬材(cai)料）做(zuo)集(ji)塵(chen)(chen)極(ji)，另一種(zhong)是用通過噴水或溢流(liu)水形成導電(dian)水膜，利(li)用不(bu)導電(dian)的非金屬材(cai)料做(zuo)集(ji)塵(chen)(chen)極(ji)。
