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(shi)式電(dian)除塵(chen)器主要(yao)有兩種結構形式，一種是使用耐(nai)(nai)腐(fu)蝕導(dao)電(dian)材(cai)(cai)料(liao)(liao)（可以為導(dao)電(dian)性能(neng)優(you)良的的非金(jin)屬材(cai)(cai)料(liao)(liao)或(huo)具有耐(nai)(nai)腐(fu)蝕特性的金(jin)屬材(cai)(cai)料(liao)(liao)）做(zuo)集塵(chen)極(ji)(ji)，另一種是用通過噴水或(huo)溢(yi)流水形成導(dao)電(dian)水膜，利用不導(dao)電(dian)的非金(jin)屬材(cai)(cai)料(liao)(liao)做(zuo)集塵(chen)極(ji)(ji)。

收塵(chen)原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)(qi)和與干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)(qi)的(de)(de)(de)收(shou)塵(chen)原(yuan)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)荷(he)(he)電(dian)(dian)(dian)(dian)，荷(he)(he)電(dian)(dian)(dian)(dian)后(hou)的(de)(de)(de)粉(fen)塵(chen)在電(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)作(zuo)用下到達(da)集(ji)塵(chen)板(ban)/管。干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)收(shou)塵(chen)器(qi)(qi)主(zhu)要處理含水(shui)很低(di)的(de)(de)(de)干(gan)氣體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)(qi)主(zhu)要處理含水(shui)較(jiao)高乃至飽和的(de)(de)(de)濕(shi)氣體。在對集(ji)塵(chen)板(ban)/管上捕集(ji)到的(de)(de)(de)粉(fen)塵(chen)清(qing)(qing)除方(fang)式(shi)(shi)上WESP與DESP有較(jiao)大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)(qi)一般采(cai)用機械振打或(huo)聲波清(qing)(qing)灰等方(fang)式(shi)(shi)清(qing)(qing)除電(dian)(dian)(dian)(dian)極上的(de)(de)(de)積灰，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)(qi)則(ze)采(cai)用定期沖(chong)洗的(de)(de)(de)方(fang)式(shi)(shi)，使粉(fen)塵(chen)隨著(zhu)沖(chong)刷液的(de)(de)(de)流動而清(qing)(qing)除。
