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。

濕式電除塵(chen)器主要有(you)兩種(zhong)結(jie)構形式，一種(zhong)是使用耐腐蝕導(dao)(dao)電材料(liao)（可以為導(dao)(dao)電性能優良的的非金屬材料(liao)或(huo)具有(you)耐腐蝕特性的金屬材料(liao)）做集(ji)塵(chen)極(ji)，另(ling)一種(zhong)是用通過噴(pen)水或(huo)溢流水形成導(dao)(dao)電水膜(mo)，利用不導(dao)(dao)電的非金屬材料(liao)做集(ji)塵(chen)極(ji)。

收(shou)塵(chen)原理

濕(shi)式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器和與(yu)干式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器的收塵(chen)(chen)原理(li)(li)相同，都是靠高壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的作(zuo)用(yong)(yong)下到達集(ji)塵(chen)(chen)板(ban)/管。干式電(dian)(dian)(dian)收塵(chen)(chen)器主要處理(li)(li)含(han)水(shui)很(hen)低(di)的干氣體，濕(shi)式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器主要處理(li)(li)含(han)水(shui)較高乃至飽(bao)和的濕(shi)氣體。在(zai)對集(ji)塵(chen)(chen)板(ban)/管上捕(bu)集(ji)到的粉(fen)塵(chen)(chen)清除(chu)(chu)(chu)方式上WESP與(yu)DESP有較大區別，干式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器一般采(cai)用(yong)(yong)機(ji)械振打或(huo)聲(sheng)波清灰等方式清除(chu)(chu)(chu)電(dian)(dian)(dian)極上的積(ji)灰，而濕(shi)式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器則采(cai)用(yong)(yong)定期沖(chong)洗的方式，使粉(fen)塵(chen)(chen)隨(sui)著(zhu)沖(chong)刷液(ye)的流動(dong)而清除(chu)(chu)(chu)。
