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(zhu)要有兩種(zhong)結(jie)構形(xing)式，一(yi)種(zhong)是使(shi)用(yong)耐腐(fu)蝕導(dao)電材料（可以為導(dao)電性能優良的的非金屬(shu)材料或(huo)具有耐腐(fu)蝕特性的金屬(shu)材料）做集塵(chen)極，另一(yi)種(zhong)是用(yong)通過噴水或(huo)溢流水形(xing)成導(dao)電水膜，利用(yong)不導(dao)電的非金屬(shu)材料做集塵(chen)極。

濕式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器和(he)與干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)(de)收(shou)塵(chen)原理(li)相同，都是靠高壓電(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)使得粉塵(chen)荷電(dian)(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)(dian)后的(de)(de)(de)粉塵(chen)在電(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)作用(yong)下到達集(ji)塵(chen)板(ban)/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)收(shou)塵(chen)器主(zhu)要處理(li)含(han)水很(hen)低(di)的(de)(de)(de)干(gan)氣體，濕式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器主(zhu)要處理(li)含(han)水較高乃至飽和(he)的(de)(de)(de)濕氣體。在對集(ji)塵(chen)板(ban)/管(guan)上(shang)捕集(ji)到的(de)(de)(de)粉塵(chen)清(qing)除(chu)(chu)方(fang)(fang)式(shi)(shi)上(shang)WESP與DESP有較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器一般采用(yong)機械(xie)振打或聲波(bo)清(qing)灰等方(fang)(fang)式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)積灰，而濕式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器則(ze)采用(yong)定(ding)期(qi)沖洗的(de)(de)(de)方(fang)(fang)式(shi)(shi)，使粉塵(chen)隨著沖刷液的(de)(de)(de)流動而清(qing)除(chu)(chu)。
