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)除塵器主要有兩種結(jie)構形(xing)式，一(yi)種是使用耐(nai)腐蝕(shi)導(dao)電(dian)材料(liao)(liao)（可以(yi)為導(dao)電(dian)性(xing)能優(you)良的的非(fei)金屬材料(liao)(liao)或具有耐(nai)腐蝕(shi)特性(xing)的金屬材料(liao)(liao)）做集(ji)塵極，另一(yi)種是用通過噴(pen)水或溢流水形(xing)成導(dao)電(dian)水膜，利(li)用不(bu)導(dao)電(dian)的非(fei)金屬材料(liao)(liao)做集(ji)塵極。
