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)(dian)(dian)(dian)除塵(chen)器主要有兩種(zhong)結構形式，一種(zhong)是使(shi)用(yong)耐腐蝕導電(dian)(dian)(dian)(dian)材料(liao)（可以為(wei)導電(dian)(dian)(dian)(dian)性能優良的(de)的(de)非金屬材料(liao)或(huo)具有耐腐蝕特(te)性的(de)金屬材料(liao)）做(zuo)集塵(chen)極，另(ling)一種(zhong)是用(yong)通過噴水或(huo)溢流水形成導電(dian)(dian)(dian)(dian)水膜，利(li)用(yong)不導電(dian)(dian)(dian)(dian)的(de)非金屬材料(liao)做(zuo)集塵(chen)極。
