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(shi)電(dian)除塵(chen)器主(zhu)要有(you)兩種(zhong)結(jie)構形(xing)式(shi)，一種(zhong)是使用耐(nai)腐(fu)(fu)蝕(shi)導電(dian)材(cai)料(liao)(liao)(liao)（可以為導電(dian)性(xing)能優良的(de)的(de)非金屬材(cai)料(liao)(liao)(liao)或(huo)具有(you)耐(nai)腐(fu)(fu)蝕(shi)特(te)性(xing)的(de)金屬材(cai)料(liao)(liao)(liao)）做(zuo)集塵(chen)極，另(ling)一種(zhong)是用通過噴水或(huo)溢流水形(xing)成導電(dian)水膜，利用不導電(dian)的(de)非金屬材(cai)料(liao)(liao)(liao)做(zuo)集塵(chen)極。
