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)式電(dian)除塵器(qi)主要有兩(liang)種(zhong)結構形式，一種(zhong)是使(shi)用耐(nai)腐蝕導電(dian)材(cai)(cai)料(liao)（可以為導電(dian)性(xing)能(neng)優良的(de)的(de)非金屬材(cai)(cai)料(liao)或(huo)具有耐(nai)腐蝕特性(xing)的(de)金屬材(cai)(cai)料(liao)）做集塵極，另一種(zhong)是用通(tong)過噴(pen)水或(huo)溢(yi)流(liu)水形成導電(dian)水膜，利(li)用不導電(dian)的(de)非金屬材(cai)(cai)料(liao)做集塵極。

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器和與干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)(de)(de)收(shou)塵(chen)(chen)(chen)原理(li)相同，都是(shi)靠高(gao)壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使(shi)得(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)(de)作用(yong)下到(dao)達(da)集(ji)(ji)塵(chen)(chen)(chen)板/管。干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)器主要(yao)(yao)處理(li)含(han)水(shui)很低的(de)(de)(de)(de)干(gan)(gan)氣(qi)(qi)體，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器主要(yao)(yao)處理(li)含(han)水(shui)較高(gao)乃(nai)至飽和的(de)(de)(de)(de)濕氣(qi)(qi)體。在對集(ji)(ji)塵(chen)(chen)(chen)板/管上捕集(ji)(ji)到(dao)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)清(qing)(qing)(qing)除(chu)(chu)方(fang)式(shi)(shi)上WESP與DESP有(you)較大區別，干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器一(yi)般采用(yong)機械振打或聲(sheng)波清(qing)(qing)(qing)灰等方(fang)式(shi)(shi)清(qing)(qing)(qing)除(chu)(chu)電(dian)(dian)(dian)極上的(de)(de)(de)(de)積灰，而濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器則采用(yong)定期沖(chong)洗的(de)(de)(de)(de)方(fang)式(shi)(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)隨著沖(chong)刷液的(de)(de)(de)(de)流動(dong)而清(qing)(qing)(qing)除(chu)(chu)。
