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)(zhong)結構形(xing)式，一種(zhong)(zhong)是使(shi)用耐腐(fu)蝕導(dao)(dao)電(dian)(dian)材料（可以為導(dao)(dao)電(dian)(dian)性(xing)能優(you)良的的非金屬材料或具有耐腐(fu)蝕特性(xing)的金屬材料）做(zuo)集(ji)塵(chen)極，另一種(zhong)(zhong)是用通過噴水(shui)(shui)或溢流水(shui)(shui)形(xing)成導(dao)(dao)電(dian)(dian)水(shui)(shui)膜(mo)，利(li)用不(bu)導(dao)(dao)電(dian)(dian)的非金屬材料做(zuo)集(ji)塵(chen)極。

收塵(chen)原理(li)

濕(shi)式電(dian)(dian)(dian)除(chu)塵(chen)(chen)器和(he)與(yu)(yu)干(gan)式電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)收(shou)塵(chen)(chen)原理(li)相(xiang)同(tong)，都(dou)是(shi)靠高(gao)壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使得粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)(de)粉塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)(yong)下到達集塵(chen)(chen)板(ban)/管。干(gan)式電(dian)(dian)(dian)收(shou)塵(chen)(chen)器主要處理(li)含(han)水(shui)很低的(de)(de)(de)干(gan)氣體，濕(shi)式電(dian)(dian)(dian)除(chu)塵(chen)(chen)器主要處理(li)含(han)水(shui)較高(gao)乃(nai)至(zhi)飽和(he)的(de)(de)(de)濕(shi)氣體。在對集塵(chen)(chen)板(ban)/管上捕集到的(de)(de)(de)粉塵(chen)(chen)清除(chu)方式上WESP與(yu)(yu)DESP有較大(da)區別，干(gan)式電(dian)(dian)(dian)除(chu)塵(chen)(chen)器一般(ban)采(cai)用(yong)(yong)機械振(zhen)打(da)或聲(sheng)波(bo)清灰等方式清除(chu)電(dian)(dian)(dian)極上的(de)(de)(de)積灰，而濕(shi)式電(dian)(dian)(dian)除(chu)塵(chen)(chen)器則(ze)采(cai)用(yong)(yong)定期沖洗的(de)(de)(de)方式，使粉塵(chen)(chen)隨(sui)著沖刷液的(de)(de)(de)流(liu)動而清除(chu)。
