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)除塵器主要(yao)有(you)兩種(zhong)結構形(xing)式，一種(zhong)是使用(yong)耐腐蝕導電(dian)材料(liao)(liao)（可以為導電(dian)性能優良的(de)(de)的(de)(de)非(fei)金屬(shu)材料(liao)(liao)或(huo)具(ju)有(you)耐腐蝕特(te)性的(de)(de)金屬(shu)材料(liao)(liao)）做(zuo)集塵極，另一種(zhong)是用(yong)通過噴水或(huo)溢流水形(xing)成(cheng)導電(dian)水膜(mo)，利(li)用(yong)不導電(dian)的(de)(de)非(fei)金屬(shu)材料(liao)(liao)做(zuo)集塵極。
