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。

濕式電除塵器(qi)主要有兩(liang)種(zhong)結構(gou)形(xing)式，一(yi)種(zhong)是使用(yong)耐腐(fu)蝕(shi)導電材料（可以為導電性(xing)能優良的(de)的(de)非金(jin)(jin)屬(shu)(shu)材料或具(ju)有耐腐(fu)蝕(shi)特(te)性(xing)的(de)金(jin)(jin)屬(shu)(shu)材料）做(zuo)集塵極，另(ling)一(yi)種(zhong)是用(yong)通過噴水(shui)或溢流水(shui)形(xing)成導電水(shui)膜，利用(yong)不導電的(de)非金(jin)(jin)屬(shu)(shu)材料做(zuo)集塵極。
