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(chu)塵(chen)(chen)器主(zhu)要有兩種(zhong)結(jie)構(gou)形(xing)式，一種(zhong)是(shi)使(shi)用耐(nai)腐蝕導(dao)(dao)電(dian)材(cai)料(liao)（可(ke)以為導(dao)(dao)電(dian)性能優良(liang)的(de)(de)的(de)(de)非金(jin)(jin)屬材(cai)料(liao)或(huo)具有耐(nai)腐蝕特(te)性的(de)(de)金(jin)(jin)屬材(cai)料(liao)）做集塵(chen)(chen)極(ji)，另一種(zhong)是(shi)用通(tong)過(guo)噴水(shui)或(huo)溢流水(shui)形(xing)成導(dao)(dao)電(dian)水(shui)膜(mo)，利用不導(dao)(dao)電(dian)的(de)(de)非金(jin)(jin)屬材(cai)料(liao)做集塵(chen)(chen)極(ji)。

收(shou)塵(chen)原理

濕(shi)式電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器和與(yu)干(gan)式電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的收塵(chen)(chen)(chen)(chen)(chen)原理(li)相同，都是靠高(gao)壓電(dian)(dian)暈(yun)放(fang)電(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的粉(fen)塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)場力的作用(yong)下到(dao)達(da)集塵(chen)(chen)(chen)(chen)(chen)板/管(guan)。干(gan)式電(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)器主要處(chu)理(li)含水很低的干(gan)氣(qi)體，濕(shi)式電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器主要處(chu)理(li)含水較高(gao)乃至飽和的濕(shi)氣(qi)體。在對集塵(chen)(chen)(chen)(chen)(chen)板/管(guan)上(shang)(shang)捕集到(dao)的粉(fen)塵(chen)(chen)(chen)(chen)(chen)清(qing)除(chu)方(fang)式上(shang)(shang)WESP與(yu)DESP有較大區別，干(gan)式電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器一般采用(yong)機(ji)械振打(da)或聲波清(qing)灰(hui)等方(fang)式清(qing)除(chu)電(dian)(dian)極上(shang)(shang)的積灰(hui)，而濕(shi)式電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器則(ze)采用(yong)定(ding)期沖(chong)(chong)洗的方(fang)式，使粉(fen)塵(chen)(chen)(chen)(chen)(chen)隨著沖(chong)(chong)刷(shua)液的流(liu)動(dong)而清(qing)除(chu)。
