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)除塵(chen)器主要有(you)兩種(zhong)結構形式，一種(zhong)是使用(yong)耐(nai)(nai)腐蝕導(dao)(dao)電(dian)材(cai)料(liao)（可以為導(dao)(dao)電(dian)性能優良的的非金屬材(cai)料(liao)或(huo)具有(you)耐(nai)(nai)腐蝕特性的金屬材(cai)料(liao)）做集塵(chen)極(ji)，另一種(zhong)是用(yong)通(tong)過噴水(shui)或(huo)溢(yi)流水(shui)形成導(dao)(dao)電(dian)水(shui)膜，利(li)用(yong)不導(dao)(dao)電(dian)的非金屬材(cai)料(liao)做集塵(chen)極(ji)。
