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)除塵器主要有兩種(zhong)結構形(xing)(xing)式，一種(zhong)是(shi)使用(yong)耐腐(fu)蝕導電(dian)材(cai)料（可(ke)以為導電(dian)性能優良(liang)的的非金屬材(cai)料或具有耐腐(fu)蝕特性的金屬材(cai)料）做集塵極，另一種(zhong)是(shi)用(yong)通過(guo)噴水或溢流水形(xing)(xing)成導電(dian)水膜(mo)，利用(yong)不導電(dian)的非金屬材(cai)料做集塵極。
