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)除塵器主要有(you)兩種(zhong)(zhong)結構形式，一(yi)種(zhong)(zhong)是使(shi)用耐腐蝕導(dao)電(dian)材(cai)料(liao)(liao)(liao)（可(ke)以為(wei)導(dao)電(dian)性能優(you)良的(de)的(de)非金屬材(cai)料(liao)(liao)(liao)或具(ju)有(you)耐腐蝕特性的(de)金屬材(cai)料(liao)(liao)(liao)）做(zuo)集塵極(ji)，另一(yi)種(zhong)(zhong)是用通(tong)過噴水(shui)或溢(yi)流水(shui)形成導(dao)電(dian)水(shui)膜，利用不導(dao)電(dian)的(de)非金屬材(cai)料(liao)(liao)(liao)做(zuo)集塵極(ji)。

濕式(shi)(shi)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器和與干(gan)(gan)(gan)式(shi)(shi)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)收塵(chen)(chen)(chen)(chen)(chen)原理(li)相(xiang)同，都是靠高壓電(dian)(dian)暈放電(dian)(dian)使(shi)(shi)得粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)，荷(he)電(dian)(dian)后的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)場力(li)的(de)作用下到(dao)達集(ji)塵(chen)(chen)(chen)(chen)(chen)板/管(guan)。干(gan)(gan)(gan)式(shi)(shi)電(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)器主要處(chu)理(li)含(han)水很低的(de)干(gan)(gan)(gan)氣體，濕式(shi)(shi)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器主要處(chu)理(li)含(han)水較(jiao)高乃至飽和的(de)濕氣體。在對集(ji)塵(chen)(chen)(chen)(chen)(chen)板/管(guan)上捕集(ji)到(dao)的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)清除方式(shi)(shi)上WESP與DESP有(you)較(jiao)大區(qu)別，干(gan)(gan)(gan)式(shi)(shi)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器一般采用機(ji)械振打或聲波(bo)清灰等方式(shi)(shi)清除電(dian)(dian)極(ji)上的(de)積灰，而(er)濕式(shi)(shi)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器則采用定(ding)期沖(chong)洗的(de)方式(shi)(shi)，使(shi)(shi)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)隨著沖(chong)刷液的(de)流動(dong)而(er)清除。
