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)(dian)(dian)除塵(chen)器主要有兩種結(jie)構(gou)形式(shi)，一種是使用耐腐(fu)蝕導(dao)電(dian)(dian)(dian)材料(liao)（可以為導(dao)電(dian)(dian)(dian)性(xing)能(neng)優良的的非金屬材料(liao)或具有耐腐(fu)蝕特(te)性(xing)的金屬材料(liao)）做集塵(chen)極(ji)，另一種是用通過噴水或溢流(liu)水形成導(dao)電(dian)(dian)(dian)水膜(mo)，利(li)用不導(dao)電(dian)(dian)(dian)的非金屬材料(liao)做集塵(chen)極(ji)。
