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(shi)電(dian)除塵(chen)器主要有(you)兩(liang)種結構形式(shi)，一種是(shi)使用耐(nai)腐蝕(shi)導電(dian)材料(liao)（可以為導電(dian)性能(neng)優良的(de)(de)的(de)(de)非(fei)金(jin)屬材料(liao)或具(ju)有(you)耐(nai)腐蝕(shi)特性的(de)(de)金(jin)屬材料(liao)）做集(ji)(ji)塵(chen)極，另(ling)一種是(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(de)(de)非(fei)金(jin)屬材料(liao)做集(ji)(ji)塵(chen)極。
