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)(dian)除塵器(qi)主要有兩種(zhong)結構形式，一種(zhong)是(shi)使用耐腐蝕(shi)導(dao)(dao)電(dian)(dian)材(cai)(cai)料(liao)（可(ke)以為導(dao)(dao)電(dian)(dian)性(xing)能(neng)優良的的非(fei)金(jin)屬(shu)材(cai)(cai)料(liao)或(huo)具有耐腐蝕(shi)特性(xing)的金(jin)屬(shu)材(cai)(cai)料(liao)）做集塵極，另(ling)一種(zhong)是(shi)用通過噴水(shui)或(huo)溢(yi)流(liu)水(shui)形成(cheng)導(dao)(dao)電(dian)(dian)水(shui)膜(mo)，利用不導(dao)(dao)電(dian)(dian)的非(fei)金(jin)屬(shu)材(cai)(cai)料(liao)做集塵極。
