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(chu)塵(chen)器主(zhu)要有兩(liang)種結構形(xing)式(shi)，一種是(shi)使(shi)用(yong)耐腐蝕(shi)導(dao)(dao)電(dian)材(cai)(cai)料（可以為導(dao)(dao)電(dian)性(xing)能優良的(de)(de)(de)的(de)(de)(de)非金(jin)屬材(cai)(cai)料或(huo)具(ju)有耐腐蝕(shi)特性(xing)的(de)(de)(de)金(jin)屬材(cai)(cai)料）做集(ji)塵(chen)極，另一種是(shi)用(yong)通過噴水(shui)或(huo)溢(yi)流水(shui)形(xing)成(cheng)導(dao)(dao)電(dian)水(shui)膜，利(li)用(yong)不導(dao)(dao)電(dian)的(de)(de)(de)非金(jin)屬材(cai)(cai)料做集(ji)塵(chen)極。
