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)除塵器主要有(you)兩種(zhong)結構形式，一(yi)種(zhong)是(shi)使用耐腐(fu)蝕(shi)導(dao)電(dian)材(cai)(cai)料(liao)(liao)（可(ke)以為導(dao)電(dian)性能(neng)優(you)良(liang)的的非金(jin)屬材(cai)(cai)料(liao)(liao)或具(ju)有(you)耐腐(fu)蝕(shi)特性的金(jin)屬材(cai)(cai)料(liao)(liao)）做(zuo)集(ji)(ji)塵極，另(ling)一(yi)種(zhong)是(shi)用通(tong)過噴水(shui)或溢(yi)流水(shui)形成導(dao)電(dian)水(shui)膜(mo)，利用不導(dao)電(dian)的非金(jin)屬材(cai)(cai)料(liao)(liao)做(zuo)集(ji)(ji)塵極。

收塵原理

濕(shi)(shi)式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)和與干式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)收(shou)塵(chen)(chen)(chen)(chen)原理相同(tong)，都是靠高壓電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉(fen)塵(chen)(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)作用下到達集(ji)塵(chen)(chen)(chen)(chen)板(ban)/管。干式電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)主要處(chu)理含(han)(han)水很低的(de)干氣體，濕(shi)(shi)式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)主要處(chu)理含(han)(han)水較高乃至飽和的(de)濕(shi)(shi)氣體。在(zai)對集(ji)塵(chen)(chen)(chen)(chen)板(ban)/管上捕集(ji)到的(de)粉(fen)塵(chen)(chen)(chen)(chen)清(qing)除(chu)方(fang)式上WESP與DESP有較大區別，干式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)一般采用機械振打或聲波清(qing)灰(hui)等方(fang)式清(qing)除(chu)電(dian)(dian)(dian)極上的(de)積灰(hui)，而(er)濕(shi)(shi)式電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)則采用定期沖洗的(de)方(fang)式，使粉(fen)塵(chen)(chen)(chen)(chen)隨著沖刷液的(de)流(liu)動(dong)而(er)清(qing)除(chu)。
