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(shi)電除塵器(qi)主(zhu)要有(you)兩(liang)種結構形式(shi)，一(yi)種是使(shi)用耐腐(fu)蝕導電材料（可以為導電性能優良(liang)的(de)的(de)非(fei)(fei)金(jin)屬材料或具有(you)耐腐(fu)蝕特性的(de)金(jin)屬材料）做集(ji)塵極，另一(yi)種是用通過噴水或溢(yi)流水形成導電水膜，利用不導電的(de)非(fei)(fei)金(jin)屬材料做集(ji)塵極。

濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器和(he)與干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)收塵(chen)(chen)(chen)(chen)原理相同，都是靠高壓(ya)電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)，荷(he)(he)電(dian)(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力(li)的(de)(de)作用下到達集塵(chen)(chen)(chen)(chen)板/管。干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器主(zhu)要處理含水(shui)很低的(de)(de)干(gan)(gan)氣體(ti)，濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器主(zhu)要處理含水(shui)較(jiao)(jiao)高乃(nai)至飽和(he)的(de)(de)濕(shi)氣體(ti)。在對(dui)集塵(chen)(chen)(chen)(chen)板/管上捕(bu)集到的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)清(qing)(qing)除(chu)方式(shi)(shi)上WESP與DESP有較(jiao)(jiao)大區(qu)別，干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器一般采(cai)(cai)用機械振打或聲(sheng)波(bo)清(qing)(qing)灰等方式(shi)(shi)清(qing)(qing)除(chu)電(dian)(dian)(dian)(dian)極上的(de)(de)積灰，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器則采(cai)(cai)用定期沖(chong)洗的(de)(de)方式(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)隨著沖(chong)刷(shua)液的(de)(de)流動而清(qing)(qing)除(chu)。
