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)除塵(chen)(chen)器主要(yao)有兩種結構形式(shi)，一(yi)種是使(shi)用耐(nai)腐(fu)蝕導(dao)電(dian)材(cai)(cai)料(liao)(liao)（可以(yi)為(wei)導(dao)電(dian)性能優良的的非(fei)金(jin)(jin)屬材(cai)(cai)料(liao)(liao)或具(ju)有耐(nai)腐(fu)蝕特性的金(jin)(jin)屬材(cai)(cai)料(liao)(liao)）做集塵(chen)(chen)極(ji)，另一(yi)種是用通過噴水(shui)或溢(yi)流水(shui)形成導(dao)電(dian)水(shui)膜，利用不導(dao)電(dian)的非(fei)金(jin)(jin)屬材(cai)(cai)料(liao)(liao)做集塵(chen)(chen)極(ji)。
