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)式電除塵器主要有兩種結構形(xing)式，一種是使用(yong)耐(nai)腐蝕導(dao)電材(cai)料（可以為導(dao)電性能優(you)良(liang)的(de)的(de)非金屬(shu)材(cai)料或具有耐(nai)腐蝕特性的(de)金屬(shu)材(cai)料）做(zuo)集塵極(ji)(ji)，另一種是用(yong)通(tong)過(guo)噴水或溢流水形(xing)成(cheng)導(dao)電水膜，利用(yong)不導(dao)電的(de)非金屬(shu)材(cai)料做(zuo)集塵極(ji)(ji)。

收(shou)塵原理

濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)和(he)與干(gan)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的收塵(chen)(chen)(chen)(chen)原理相同，都(dou)是靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場(chang)力的作用下到達集塵(chen)(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器(qi)主要處理含水(shui)很低(di)的干(gan)氣體(ti)，濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)主要處理含水(shui)較(jiao)高乃(nai)至飽和(he)的濕(shi)氣體(ti)。在對(dui)集塵(chen)(chen)(chen)(chen)板/管(guan)上捕(bu)集到的粉(fen)塵(chen)(chen)(chen)(chen)清除(chu)(chu)方(fang)式(shi)上WESP與DESP有較(jiao)大(da)區(qu)別，干(gan)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)一般(ban)采(cai)用機(ji)械振打或聲波清灰等方(fang)式(shi)清除(chu)(chu)電(dian)(dian)(dian)極(ji)上的積灰，而濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)則采(cai)用定期沖(chong)洗的方(fang)式(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)(chen)隨著沖(chong)刷液的流(liu)動而清除(chu)(chu)。
