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(zhu)要有兩種結構形式，一種是(shi)(shi)使用耐(nai)腐(fu)蝕(shi)導(dao)(dao)電材(cai)(cai)料(liao)(liao)（可以為(wei)導(dao)(dao)電性能優良的的非(fei)金(jin)屬(shu)材(cai)(cai)料(liao)(liao)或(huo)具有耐(nai)腐(fu)蝕(shi)特(te)性的金(jin)屬(shu)材(cai)(cai)料(liao)(liao)）做集塵極，另一種是(shi)(shi)用通過噴水(shui)或(huo)溢流(liu)水(shui)形成(cheng)導(dao)(dao)電水(shui)膜，利用不導(dao)(dao)電的非(fei)金(jin)屬(shu)材(cai)(cai)料(liao)(liao)做集塵極。
