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)(dian)除塵(chen)器主要有兩種結構(gou)形式，一(yi)(yi)種是使用耐(nai)腐蝕導電(dian)(dian)材(cai)料(liao)(liao)（可以(yi)為(wei)導電(dian)(dian)性能優(you)良的(de)的(de)非金(jin)屬材(cai)料(liao)(liao)或具有耐(nai)腐蝕特性的(de)金(jin)屬材(cai)料(liao)(liao)）做集塵(chen)極，另一(yi)(yi)種是用通過噴水(shui)(shui)或溢流水(shui)(shui)形成導電(dian)(dian)水(shui)(shui)膜(mo)，利用不(bu)導電(dian)(dian)的(de)非金(jin)屬材(cai)料(liao)(liao)做集塵(chen)極。

收塵(chen)原理

濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)和(he)與干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的收塵(chen)(chen)(chen)原理相同，都是(shi)靠高(gao)壓電(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)(dian)場力的作用下到達集塵(chen)(chen)(chen)板/管。干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主要(yao)處(chu)理含水很低(di)的干(gan)氣(qi)(qi)體(ti)，濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)主要(yao)處(chu)理含水較高(gao)乃(nai)至(zhi)飽和(he)的濕(shi)(shi)氣(qi)(qi)體(ti)。在對集塵(chen)(chen)(chen)板/管上捕集到的粉(fen)塵(chen)(chen)(chen)清除(chu)方式(shi)(shi)上WESP與DESP有較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)一般采用機械振打或聲波(bo)清灰等方式(shi)(shi)清除(chu)電(dian)(dian)(dian)(dian)(dian)極上的積灰，而濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)則(ze)采用定期沖洗的方式(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)隨(sui)著沖刷液的流動而清除(chu)。
