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(shi)電(dian)(dian)除塵器主(zhu)要(yao)有兩(liang)種(zhong)結構形式(shi)，一(yi)種(zhong)是使用耐腐蝕導電(dian)(dian)材料（可(ke)以(yi)為(wei)導電(dian)(dian)性能(neng)優(you)良(liang)的(de)的(de)非金屬材料或具有耐腐蝕特性的(de)金屬材料）做集塵極，另一(yi)種(zhong)是用通過噴水或溢流水形成(cheng)導電(dian)(dian)水膜，利用不導電(dian)(dian)的(de)非金屬材料做集塵極。

收塵原理

濕式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)和(he)與干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)的收塵(chen)(chen)(chen)原理(li)(li)相同，都是(shi)靠高(gao)壓(ya)電(dian)(dian)暈(yun)放(fang)電(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)，荷(he)電(dian)(dian)后(hou)的粉塵(chen)(chen)(chen)在電(dian)(dian)場力的作用下到達集塵(chen)(chen)(chen)板/管(guan)。干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)主要(yao)處理(li)(li)含(han)(han)水很(hen)低的干(gan)(gan)氣(qi)體，濕式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)主要(yao)處理(li)(li)含(han)(han)水較高(gao)乃至飽和(he)的濕氣(qi)體。在對集塵(chen)(chen)(chen)板/管(guan)上捕集到的粉塵(chen)(chen)(chen)清(qing)除(chu)方式(shi)(shi)(shi)上WESP與DESP有較大區(qu)別，干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)一般采(cai)用機械振(zhen)打或聲波清(qing)灰(hui)等方式(shi)(shi)(shi)清(qing)除(chu)電(dian)(dian)極上的積(ji)灰(hui)，而濕式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)則采(cai)用定期沖洗(xi)的方式(shi)(shi)(shi)，使(shi)粉塵(chen)(chen)(chen)隨著沖刷液的流動而清(qing)除(chu)。
