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)式電除(chu)塵器主(zhu)要(yao)有兩種結構形式，一種是使用(yong)(yong)耐腐蝕導(dao)(dao)(dao)電材料（可以為導(dao)(dao)(dao)電性能優良的的非金(jin)屬(shu)(shu)材料或具有耐腐蝕特性的金(jin)屬(shu)(shu)材料）做集塵極(ji)(ji)，另一種是用(yong)(yong)通過噴水(shui)(shui)或溢流水(shui)(shui)形成導(dao)(dao)(dao)電水(shui)(shui)膜，利用(yong)(yong)不導(dao)(dao)(dao)電的非金(jin)屬(shu)(shu)材料做集塵極(ji)(ji)。

收塵原理

濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)和與(yu)干(gan)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的收塵(chen)(chen)原理相同，都(dou)是靠高壓電(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的作用下(xia)到達集塵(chen)(chen)板(ban)/管。干(gan)式(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)主要(yao)處理含(han)水(shui)(shui)很(hen)低(di)的干(gan)氣體(ti)，濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)主要(yao)處理含(han)水(shui)(shui)較(jiao)高乃(nai)至飽(bao)和的濕氣體(ti)。在(zai)對集塵(chen)(chen)板(ban)/管上(shang)捕集到的粉(fen)塵(chen)(chen)清(qing)除(chu)方(fang)式(shi)上(shang)WESP與(yu)DESP有較(jiao)大區別，干(gan)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)一般(ban)采(cai)用機(ji)械振(zhen)打(da)或(huo)聲波清(qing)灰(hui)等方(fang)式(shi)清(qing)除(chu)電(dian)(dian)(dian)極上(shang)的積(ji)灰(hui)，而濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)則采(cai)用定期沖洗的方(fang)式(shi)，使粉(fen)塵(chen)(chen)隨(sui)著沖刷液的流動而清(qing)除(chu)。
