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)除塵器主要有(you)兩種(zhong)結(jie)構形(xing)式，一種(zhong)是使用(yong)耐(nai)(nai)腐蝕導(dao)電(dian)(dian)材料(liao)（可(ke)以為導(dao)電(dian)(dian)性能(neng)優良的(de)的(de)非金屬(shu)材料(liao)或(huo)具有(you)耐(nai)(nai)腐蝕特性的(de)金屬(shu)材料(liao)）做(zuo)集塵極，另(ling)一種(zhong)是用(yong)通(tong)過噴水(shui)或(huo)溢流水(shui)形(xing)成導(dao)電(dian)(dian)水(shui)膜，利用(yong)不導(dao)電(dian)(dian)的(de)非金屬(shu)材料(liao)做(zuo)集塵極。

收塵(chen)原理

濕(shi)式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)和與(yu)(yu)干式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)(chen)(chen)(chen)(chen)原理相同，都是(shi)靠高(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用下到達(da)集塵(chen)(chen)(chen)(chen)(chen)(chen)板/管(guan)。干式電(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)主要(yao)處理含水(shui)很低的(de)(de)干氣(qi)(qi)體(ti)，濕(shi)式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)主要(yao)處理含水(shui)較(jiao)高(gao)乃至飽(bao)和的(de)(de)濕(shi)氣(qi)(qi)體(ti)。在對(dui)集塵(chen)(chen)(chen)(chen)(chen)(chen)板/管(guan)上捕集到的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)清(qing)(qing)除(chu)方式上WESP與(yu)(yu)DESP有較(jiao)大(da)區別，干式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)一般(ban)采用機械振打或聲波清(qing)(qing)灰等方式清(qing)(qing)除(chu)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)積(ji)灰，而濕(shi)式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)則采用定期(qi)沖洗的(de)(de)方式，使(shi)粉塵(chen)(chen)(chen)(chen)(chen)(chen)隨著沖刷液的(de)(de)流動而清(qing)(qing)除(chu)。
