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。

濕式電除(chu)塵(chen)器主(zhu)要有兩種(zhong)結構形式，一種(zhong)是使用(yong)(yong)耐(nai)腐(fu)蝕導(dao)電材(cai)料(liao)（可(ke)以為導(dao)電性能優(you)良(liang)的的非金屬材(cai)料(liao)或具有耐(nai)腐(fu)蝕特性的金屬材(cai)料(liao)）做集(ji)塵(chen)極，另一種(zhong)是用(yong)(yong)通過噴(pen)水(shui)或溢流水(shui)形成導(dao)電水(shui)膜，利用(yong)(yong)不導(dao)電的非金屬材(cai)料(liao)做集(ji)塵(chen)極。

收塵原理

濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)和與(yu)干(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)(chen)原(yuan)理(li)相同，都是(shi)靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)作用下到(dao)達集塵(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主要處理(li)含水很(hen)低的(de)(de)干(gan)氣體，濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)主要處理(li)含水較高乃至飽和的(de)(de)濕(shi)氣體。在(zai)對集塵(chen)(chen)(chen)板/管(guan)上捕(bu)集到(dao)的(de)(de)粉(fen)塵(chen)(chen)(chen)清(qing)(qing)除(chu)方(fang)式(shi)(shi)(shi)(shi)上WESP與(yu)DESP有較大區別，干(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)一般采用機械(xie)振打或聲波清(qing)(qing)灰(hui)等方(fang)式(shi)(shi)(shi)(shi)清(qing)(qing)除(chu)電(dian)(dian)(dian)極上的(de)(de)積灰(hui)，而濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)則采用定期沖洗的(de)(de)方(fang)式(shi)(shi)(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)隨著沖刷液的(de)(de)流動(dong)而清(qing)(qing)除(chu)。
