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(qi)主要有(you)兩種(zhong)(zhong)結構(gou)形式，一(yi)種(zhong)(zhong)是(shi)使(shi)用耐腐蝕(shi)導電(dian)材料（可以為(wei)導電(dian)性(xing)能優(you)良的的非金(jin)屬(shu)(shu)材料或具有(you)耐腐蝕(shi)特性(xing)的金(jin)屬(shu)(shu)材料）做(zuo)(zuo)集(ji)塵極，另一(yi)種(zhong)(zhong)是(shi)用通過噴水或溢流(liu)水形成(cheng)導電(dian)水膜，利用不導電(dian)的非金(jin)屬(shu)(shu)材料做(zuo)(zuo)集(ji)塵極。
