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)除塵器主要(yao)有(you)兩種(zhong)結構(gou)形式，一種(zhong)是(shi)使用(yong)耐腐蝕導電(dian)材料（可以為(wei)導電(dian)性能優(you)良的(de)的(de)非金(jin)(jin)屬材料或(huo)具有(you)耐腐蝕特性的(de)金(jin)(jin)屬材料）做集(ji)塵極(ji)，另一種(zhong)是(shi)用(yong)通(tong)過噴水或(huo)溢(yi)流水形成導電(dian)水膜，利(li)用(yong)不導電(dian)的(de)非金(jin)(jin)屬材料做集(ji)塵極(ji)。

收塵(chen)原理

濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵器和與(yu)干式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵器的(de)(de)(de)收(shou)塵原理相(xiang)同，都(dou)是(shi)靠高壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)塵荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后的(de)(de)(de)粉(fen)塵在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下到達(da)集塵板(ban)/管(guan)(guan)。干式(shi)電(dian)(dian)(dian)(dian)收(shou)塵器主(zhu)要處理含水很低的(de)(de)(de)干氣體(ti)，濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵器主(zhu)要處理含水較高乃至飽和的(de)(de)(de)濕(shi)(shi)氣體(ti)。在對集塵板(ban)/管(guan)(guan)上(shang)捕集到的(de)(de)(de)粉(fen)塵清除(chu)(chu)方(fang)式(shi)上(shang)WESP與(yu)DESP有(you)較大區(qu)別，干式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵器一般采用(yong)機(ji)械振打(da)或聲波清灰等(deng)方(fang)式(shi)清除(chu)(chu)電(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)積灰，而濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵器則采用(yong)定期沖洗的(de)(de)(de)方(fang)式(shi)，使粉(fen)塵隨著沖刷液(ye)的(de)(de)(de)流動而清除(chu)(chu)。
