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)(dian)除(chu)塵器主要(yao)有兩種(zhong)結構形式，一種(zhong)是使用耐腐蝕(shi)導(dao)電(dian)(dian)材(cai)料（可以為(wei)導(dao)電(dian)(dian)性能(neng)優良的(de)的(de)非金(jin)屬(shu)材(cai)料或具(ju)有耐腐蝕(shi)特性的(de)金(jin)屬(shu)材(cai)料）做(zuo)集塵極(ji)，另一種(zhong)是用通過噴水(shui)或溢流水(shui)形成導(dao)電(dian)(dian)水(shui)膜，利(li)用不(bu)導(dao)電(dian)(dian)的(de)非金(jin)屬(shu)材(cai)料做(zuo)集塵極(ji)。

收塵原理(li)

濕(shi)(shi)式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)和與(yu)干式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的收塵(chen)(chen)(chen)(chen)原理(li)相同，都(dou)是靠高壓電(dian)(dian)暈放電(dian)(dian)使(shi)得粉(fen)(fen)(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的粉(fen)(fen)(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)場力(li)的作用下到(dao)達集(ji)塵(chen)(chen)(chen)(chen)板(ban)/管。干式(shi)(shi)電(dian)(dian)收塵(chen)(chen)(chen)(chen)器(qi)主要處(chu)理(li)含水很低的干氣體，濕(shi)(shi)式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)主要處(chu)理(li)含水較(jiao)高乃(nai)至飽和的濕(shi)(shi)氣體。在對集(ji)塵(chen)(chen)(chen)(chen)板(ban)/管上(shang)捕集(ji)到(dao)的粉(fen)(fen)(fen)塵(chen)(chen)(chen)(chen)清(qing)(qing)除(chu)方式(shi)(shi)上(shang)WESP與(yu)DESP有較(jiao)大區(qu)別，干式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)一般采用機械振打或聲波(bo)清(qing)(qing)灰等方式(shi)(shi)清(qing)(qing)除(chu)電(dian)(dian)極上(shang)的積灰，而(er)(er)濕(shi)(shi)式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)則(ze)采用定期沖洗(xi)的方式(shi)(shi)，使(shi)粉(fen)(fen)(fen)塵(chen)(chen)(chen)(chen)隨著沖刷(shua)液(ye)的流動而(er)(er)清(qing)(qing)除(chu)。
