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。

濕式電除塵器(qi)主要(yao)有兩種結構形式，一種是使(shi)用(yong)耐腐(fu)蝕(shi)導電材料(liao)（可以為導電性能優良(liang)的(de)的(de)非金屬材料(liao)或具有耐腐(fu)蝕(shi)特性的(de)金屬材料(liao)）做集塵極，另一種是用(yong)通過噴水(shui)(shui)或溢流水(shui)(shui)形成導電水(shui)(shui)膜，利用(yong)不(bu)導電的(de)非金屬材料(liao)做集塵極。

收(shou)塵原理

濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)(qi)和與干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)(qi)的(de)收塵(chen)原理(li)相同，都是靠高壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使(shi)得粉塵(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉塵(chen)在電(dian)(dian)(dian)(dian)場力的(de)作用(yong)下到達集塵(chen)板/管(guan)。干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)器(qi)(qi)(qi)主要處(chu)理(li)含(han)水很低的(de)干(gan)氣體，濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)(qi)主要處(chu)理(li)含(han)水較(jiao)高乃至飽和的(de)濕(shi)(shi)氣體。在對集塵(chen)板/管(guan)上捕(bu)集到的(de)粉塵(chen)清(qing)除(chu)方(fang)式(shi)(shi)(shi)上WESP與DESP有較(jiao)大區別，干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)(qi)一般采用(yong)機械振打或聲波清(qing)灰(hui)等方(fang)式(shi)(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)(dian)極上的(de)積灰(hui)，而(er)濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)(qi)則(ze)采用(yong)定(ding)期沖(chong)(chong)洗(xi)的(de)方(fang)式(shi)(shi)(shi)，使(shi)粉塵(chen)隨著沖(chong)(chong)刷液的(de)流動(dong)而(er)清(qing)除(chu)。
