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。

濕式電除(chu)塵器(qi)主要有兩種(zhong)結構(gou)形式，一(yi)種(zhong)是使(shi)用耐腐蝕導(dao)電材料(liao)（可以(yi)為導(dao)電性(xing)能(neng)優良(liang)的(de)的(de)非金(jin)(jin)屬材料(liao)或具(ju)有耐腐蝕特性(xing)的(de)金(jin)(jin)屬材料(liao)）做集(ji)塵極，另(ling)一(yi)種(zhong)是用通過噴水(shui)或溢流水(shui)形成導(dao)電水(shui)膜(mo)，利用不(bu)導(dao)電的(de)非金(jin)(jin)屬材料(liao)做集(ji)塵極。

收塵原理

濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)和與干(gan)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)的收(shou)塵(chen)(chen)原理(li)相同(tong)，都是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力(li)的作用下到達(da)集塵(chen)(chen)板(ban)/管(guan)。干(gan)式(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)器(qi)(qi)主(zhu)要(yao)處理(li)含水很低的干(gan)氣(qi)體(ti)(ti)，濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)主(zhu)要(yao)處理(li)含水較高乃至飽和的濕氣(qi)體(ti)(ti)。在(zai)對集塵(chen)(chen)板(ban)/管(guan)上捕集到的粉(fen)塵(chen)(chen)清(qing)(qing)除(chu)(chu)方式(shi)上WESP與DESP有較大區別，干(gan)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)一般采(cai)用機(ji)械振打或聲波清(qing)(qing)灰(hui)等方式(shi)清(qing)(qing)除(chu)(chu)電(dian)(dian)(dian)極上的積灰(hui)，而(er)濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)則采(cai)用定期沖洗的方式(shi)，使(shi)粉(fen)塵(chen)(chen)隨著(zhu)沖刷(shua)液的流動而(er)清(qing)(qing)除(chu)(chu)。
