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)除塵器主要(yao)有兩種結構形(xing)式，一種是使用(yong)(yong)耐腐蝕(shi)導電(dian)(dian)材(cai)料(liao)（可以(yi)為導電(dian)(dian)性(xing)能優良的的非金屬(shu)(shu)材(cai)料(liao)或(huo)具有耐腐蝕(shi)特性(xing)的金屬(shu)(shu)材(cai)料(liao)）做(zuo)集塵極(ji)，另一種是用(yong)(yong)通過噴水或(huo)溢流(liu)水形(xing)成導電(dian)(dian)水膜，利用(yong)(yong)不導電(dian)(dian)的非金屬(shu)(shu)材(cai)料(liao)做(zuo)集塵極(ji)。
