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)除塵器主要有(you)兩(liang)種結構形(xing)式，一(yi)種是使用(yong)耐(nai)腐蝕導(dao)電(dian)材(cai)料（可(ke)以為導(dao)電(dian)性能優良的的非金屬材(cai)料或(huo)具有(you)耐(nai)腐蝕特性的金屬材(cai)料）做集塵極，另一(yi)種是用(yong)通過噴水(shui)(shui)或(huo)溢(yi)流水(shui)(shui)形(xing)成導(dao)電(dian)水(shui)(shui)膜，利用(yong)不(bu)導(dao)電(dian)的非金屬材(cai)料做集塵極。

濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)和(he)與(yu)干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的收塵(chen)(chen)(chen)(chen)(chen)原理相同，都(dou)是(shi)靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力(li)的作用下(xia)到(dao)達集塵(chen)(chen)(chen)(chen)(chen)板(ban)/管。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主要處理含(han)水(shui)很低(di)的干氣體(ti)，濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主要處理含(han)水(shui)較(jiao)高乃至飽和(he)的濕氣體(ti)。在對集塵(chen)(chen)(chen)(chen)(chen)板(ban)/管上捕集到(dao)的粉(fen)塵(chen)(chen)(chen)(chen)(chen)清(qing)(qing)除(chu)方式(shi)上WESP與(yu)DESP有(you)較(jiao)大(da)區別，干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)一般采用機械(xie)振(zhen)打(da)或聲波清(qing)(qing)灰(hui)等方式(shi)清(qing)(qing)除(chu)電(dian)(dian)(dian)極上的積灰(hui)，而濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)則采用定期(qi)沖洗(xi)的方式(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)(chen)隨著沖刷液的流動而清(qing)(qing)除(chu)。
