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(chu)塵(chen)(chen)器主(zhu)要有(you)兩種(zhong)結構形式，一種(zhong)是(shi)使用(yong)耐腐蝕導(dao)(dao)電(dian)(dian)材(cai)料(liao)（可以(yi)為導(dao)(dao)電(dian)(dian)性能優良(liang)的(de)(de)的(de)(de)非(fei)(fei)金屬(shu)(shu)材(cai)料(liao)或具有(you)耐腐蝕特(te)性的(de)(de)金屬(shu)(shu)材(cai)料(liao)）做(zuo)(zuo)集塵(chen)(chen)極(ji)(ji)，另(ling)一種(zhong)是(shi)用(yong)通(tong)過噴水或溢流水形成導(dao)(dao)電(dian)(dian)水膜，利用(yong)不導(dao)(dao)電(dian)(dian)的(de)(de)非(fei)(fei)金屬(shu)(shu)材(cai)料(liao)做(zuo)(zuo)集塵(chen)(chen)極(ji)(ji)。

收塵原理

濕式電(dian)(dian)(dian)(dian)除(chu)塵(chen)器和與干式電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)(de)收塵(chen)原(yuan)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(fen)(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后的(de)(de)(de)(de)粉(fen)(fen)塵(chen)在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用(yong)下到(dao)達(da)集(ji)塵(chen)板/管。干式電(dian)(dian)(dian)(dian)收塵(chen)器主(zhu)要(yao)處理(li)含水很低的(de)(de)(de)(de)干氣體，濕式電(dian)(dian)(dian)(dian)除(chu)塵(chen)器主(zhu)要(yao)處理(li)含水較高乃至(zhi)飽和的(de)(de)(de)(de)濕氣體。在對(dui)集(ji)塵(chen)板/管上(shang)捕集(ji)到(dao)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)清(qing)(qing)除(chu)方(fang)式上(shang)WESP與DESP有較大區別，干式電(dian)(dian)(dian)(dian)除(chu)塵(chen)器一般(ban)采用(yong)機械振(zhen)打或聲波(bo)清(qing)(qing)灰(hui)等方(fang)式清(qing)(qing)除(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)(de)積灰(hui)，而濕式電(dian)(dian)(dian)(dian)除(chu)塵(chen)器則采用(yong)定期沖(chong)洗(xi)的(de)(de)(de)(de)方(fang)式，使(shi)粉(fen)(fen)塵(chen)隨著沖(chong)刷液(ye)的(de)(de)(de)(de)流動(dong)而清(qing)(qing)除(chu)。
