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)除(chu)塵(chen)器主要有兩種(zhong)結構(gou)形式，一種(zhong)是(shi)使用耐腐(fu)蝕導電(dian)(dian)材(cai)料（可以為導電(dian)(dian)性能(neng)優(you)良(liang)的的非(fei)金屬材(cai)料或具有耐腐(fu)蝕特(te)性的金屬材(cai)料）做集(ji)塵(chen)極，另一種(zhong)是(shi)用通過噴水(shui)(shui)或溢流水(shui)(shui)形成導電(dian)(dian)水(shui)(shui)膜(mo)，利用不導電(dian)(dian)的非(fei)金屬材(cai)料做集(ji)塵(chen)極。

濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)和與干(gan)(gan)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)收(shou)塵(chen)(chen)(chen)(chen)原理(li)相同，都是靠高壓電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作(zuo)用下到達集(ji)塵(chen)(chen)(chen)(chen)板/管。干(gan)(gan)式(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)(qi)主要(yao)處理(li)含水(shui)很低的(de)(de)干(gan)(gan)氣體(ti)，濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)主要(yao)處理(li)含水(shui)較高乃至飽和的(de)(de)濕氣體(ti)。在對(dui)集(ji)塵(chen)(chen)(chen)(chen)板/管上捕集(ji)到的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)清(qing)除(chu)方(fang)(fang)式(shi)上WESP與DESP有較大區別，干(gan)(gan)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)一般采用機械(xie)振(zhen)打或聲波(bo)清(qing)灰(hui)(hui)等方(fang)(fang)式(shi)清(qing)除(chu)電(dian)(dian)(dian)極(ji)上的(de)(de)積灰(hui)(hui)，而濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)則采用定期(qi)沖洗的(de)(de)方(fang)(fang)式(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)隨著沖刷液的(de)(de)流動(dong)而清(qing)除(chu)。
