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)(dian)除塵(chen)(chen)器主要有兩種(zhong)結(jie)構形式，一(yi)種(zhong)是使用耐腐蝕(shi)導電(dian)(dian)材(cai)(cai)料(liao)（可以(yi)為導電(dian)(dian)性(xing)能優良的(de)的(de)非金屬材(cai)(cai)料(liao)或具有耐腐蝕(shi)特(te)性(xing)的(de)金屬材(cai)(cai)料(liao)）做集(ji)(ji)塵(chen)(chen)極(ji)，另(ling)一(yi)種(zhong)是用通過噴水或溢流水形成導電(dian)(dian)水膜，利(li)用不導電(dian)(dian)的(de)非金屬材(cai)(cai)料(liao)做集(ji)(ji)塵(chen)(chen)極(ji)。

收塵原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)和與干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)的收塵(chen)(chen)原理相(xiang)同(tong)，都是(shi)靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉(fen)(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的作用(yong)下到達集塵(chen)(chen)板(ban)/管。干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)理含水很低的干(gan)(gan)氣體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)理含水較(jiao)高乃(nai)至(zhi)飽和的濕(shi)氣體。在(zai)對集塵(chen)(chen)板(ban)/管上捕集到的粉(fen)(fen)塵(chen)(chen)清除(chu)方式(shi)(shi)上WESP與DESP有較(jiao)大區(qu)別，干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)一(yi)般采用(yong)機械振打或聲(sheng)波清灰等方式(shi)(shi)清除(chu)電(dian)(dian)(dian)極(ji)上的積灰，而(er)濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)則采用(yong)定期(qi)沖洗(xi)的方式(shi)(shi)，使粉(fen)(fen)塵(chen)(chen)隨著沖刷液(ye)的流(liu)動而(er)清除(chu)。
