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(shi)式(shi)(shi)電(dian)除塵(chen)(chen)器主要有(you)兩種(zhong)結構形式(shi)(shi)，一種(zhong)是(shi)使用耐腐蝕導電(dian)材(cai)料（可以為導電(dian)性(xing)能優良的的非(fei)金(jin)屬(shu)材(cai)料或具有(you)耐腐蝕特性(xing)的金(jin)屬(shu)材(cai)料）做集塵(chen)(chen)極，另(ling)一種(zhong)是(shi)用通過(guo)噴(pen)水或溢流水形成導電(dian)水膜，利用不導電(dian)的非(fei)金(jin)屬(shu)材(cai)料做集塵(chen)(chen)極。
