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(shi)電(dian)(dian)除塵器(qi)主(zhu)要有兩種(zhong)結構形式(shi)，一種(zhong)是使用耐(nai)腐(fu)蝕(shi)導(dao)電(dian)(dian)材(cai)料（可(ke)以為導(dao)電(dian)(dian)性(xing)能優良的的非金屬材(cai)料或(huo)(huo)具有耐(nai)腐(fu)蝕(shi)特(te)性(xing)的金屬材(cai)料）做(zuo)(zuo)集塵極(ji)，另一種(zhong)是用通過噴水(shui)或(huo)(huo)溢流水(shui)形成導(dao)電(dian)(dian)水(shui)膜(mo)，利用不導(dao)電(dian)(dian)的非金屬材(cai)料做(zuo)(zuo)集塵極(ji)。

收塵原理

濕式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)和(he)(he)與干式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)的(de)收塵(chen)(chen)(chen)原理(li)相同，都(dou)是靠(kao)高壓電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉(fen)(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力(li)的(de)作用下到(dao)達集塵(chen)(chen)(chen)板(ban)(ban)/管。干式電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)理(li)含(han)水(shui)很低(di)的(de)干氣(qi)體(ti)，濕式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)理(li)含(han)水(shui)較高乃至飽和(he)(he)的(de)濕氣(qi)體(ti)。在(zai)對集塵(chen)(chen)(chen)板(ban)(ban)/管上(shang)捕集到(dao)的(de)粉(fen)(fen)塵(chen)(chen)(chen)清除(chu)方式上(shang)WESP與DESP有較大區別，干式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)一(yi)般(ban)采(cai)用機械(xie)振打或聲波(bo)清灰等方式清除(chu)電(dian)(dian)(dian)極上(shang)的(de)積(ji)灰，而(er)濕式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)則采(cai)用定期沖洗的(de)方式，使粉(fen)(fen)塵(chen)(chen)(chen)隨著沖刷液的(de)流動而(er)清除(chu)。
