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)(dian)除(chu)塵器主要有兩種(zhong)(zhong)結構(gou)形式，一種(zhong)(zhong)是使(shi)用耐腐蝕導(dao)電(dian)(dian)(dian)材料(liao)（可以為導(dao)電(dian)(dian)(dian)性能優良的的非金屬材料(liao)或具有耐腐蝕特性的金屬材料(liao)）做集塵極(ji)，另一種(zhong)(zhong)是用通過噴水(shui)或溢流水(shui)形成導(dao)電(dian)(dian)(dian)水(shui)膜，利(li)用不導(dao)電(dian)(dian)(dian)的非金屬材料(liao)做集塵極(ji)。

濕(shi)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)和與干(gan)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)原(yuan)理相同，都是靠高壓電(dian)(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用下到達集塵(chen)(chen)板/管(guan)。干(gan)式電(dian)(dian)(dian)(dian)收塵(chen)(chen)器(qi)主要處理含(han)水很低的(de)(de)干(gan)氣(qi)體(ti)，濕(shi)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)主要處理含(han)水較(jiao)高乃至飽和的(de)(de)濕(shi)氣(qi)體(ti)。在對(dui)集塵(chen)(chen)板/管(guan)上捕集到的(de)(de)粉(fen)塵(chen)(chen)清除方式上WESP與DESP有較(jiao)大區別，干(gan)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)一般采用機(ji)械振打或聲波清灰等方式清除電(dian)(dian)(dian)(dian)極上的(de)(de)積灰，而濕(shi)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)則采用定期沖(chong)洗的(de)(de)方式，使(shi)粉(fen)塵(chen)(chen)隨著沖(chong)刷液的(de)(de)流動而清除。
