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)除塵(chen)器(qi)主要有兩種(zhong)(zhong)結(jie)構形式(shi)，一種(zhong)(zhong)是使用耐腐蝕導(dao)(dao)電(dian)(dian)材(cai)料（可以(yi)為導(dao)(dao)電(dian)(dian)性能優良的的非金(jin)屬(shu)材(cai)料或具(ju)有耐腐蝕特性的金(jin)屬(shu)材(cai)料）做集(ji)塵(chen)極，另一種(zhong)(zhong)是用通過(guo)噴水(shui)或溢流水(shui)形成導(dao)(dao)電(dian)(dian)水(shui)膜(mo)，利用不導(dao)(dao)電(dian)(dian)的非金(jin)屬(shu)材(cai)料做集(ji)塵(chen)極。
