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，一種(zhong)是使用耐腐蝕導(dao)(dao)電(dian)材(cai)料(liao)(liao)（可(ke)以為(wei)導(dao)(dao)電(dian)性能優良的(de)(de)的(de)(de)非(fei)金(jin)屬材(cai)料(liao)(liao)或具有(you)耐腐蝕特性的(de)(de)金(jin)屬材(cai)料(liao)(liao)）做(zuo)集塵極(ji)，另一種(zhong)是用通過(guo)噴水(shui)或溢流水(shui)形成(cheng)導(dao)(dao)電(dian)水(shui)膜，利用不導(dao)(dao)電(dian)的(de)(de)非(fei)金(jin)屬材(cai)料(liao)(liao)做(zuo)集塵極(ji)。

收塵(chen)原理(li)

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)和與(yu)(yu)干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的收(shou)塵(chen)(chen)(chen)(chen)原(yuan)理(li)(li)相(xiang)同(tong)，都是靠高(gao)壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)，荷(he)(he)電(dian)(dian)(dian)后(hou)的粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的作用(yong)下(xia)到(dao)達(da)集(ji)塵(chen)(chen)(chen)(chen)板/管。干(gan)式(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)主(zhu)要處理(li)(li)含水很低(di)的干(gan)氣體，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)主(zhu)要處理(li)(li)含水較高(gao)乃至飽和的濕氣體。在對集(ji)塵(chen)(chen)(chen)(chen)板/管上捕集(ji)到(dao)的粉(fen)塵(chen)(chen)(chen)(chen)清(qing)(qing)除(chu)(chu)方式(shi)(shi)上WESP與(yu)(yu)DESP有較大(da)區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)一(yi)般采用(yong)機械(xie)振打或(huo)聲波清(qing)(qing)灰等方式(shi)(shi)清(qing)(qing)除(chu)(chu)電(dian)(dian)(dian)極上的積灰，而(er)濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)則采用(yong)定期沖(chong)洗的方式(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)隨著沖(chong)刷液的流動(dong)而(er)清(qing)(qing)除(chu)(chu)。
