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。

濕式電除塵器主要(yao)有兩(liang)種(zhong)結構形(xing)式，一種(zhong)是使用耐腐(fu)蝕導(dao)(dao)電材(cai)(cai)料(liao)（可(ke)以為(wei)導(dao)(dao)電性能優良的的非金(jin)屬(shu)材(cai)(cai)料(liao)或具有耐腐(fu)蝕特性的金(jin)屬(shu)材(cai)(cai)料(liao)）做集塵極(ji)，另一種(zhong)是用通過(guo)噴(pen)水(shui)或溢流水(shui)形(xing)成(cheng)導(dao)(dao)電水(shui)膜，利用不導(dao)(dao)電的非金(jin)屬(shu)材(cai)(cai)料(liao)做集塵極(ji)。
