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(qi)主要有兩種(zhong)(zhong)結構(gou)形式，一(yi)種(zhong)(zhong)是使(shi)用(yong)耐腐(fu)蝕導(dao)(dao)電(dian)材料(liao)(liao)(liao)（可以為導(dao)(dao)電(dian)性能優良(liang)的(de)的(de)非(fei)金(jin)(jin)屬(shu)材料(liao)(liao)(liao)或具有耐腐(fu)蝕特性的(de)金(jin)(jin)屬(shu)材料(liao)(liao)(liao)）做集(ji)塵極，另一(yi)種(zhong)(zhong)是用(yong)通過噴水或溢流水形成導(dao)(dao)電(dian)水膜，利用(yong)不導(dao)(dao)電(dian)的(de)非(fei)金(jin)(jin)屬(shu)材料(liao)(liao)(liao)做集(ji)塵極。

濕式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)和與干式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)的(de)收塵(chen)(chen)(chen)原理相同，都是靠高(gao)壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)粉塵(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)作用下到達集塵(chen)(chen)(chen)板(ban)/管(guan)。干式電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)(qi)主要處理含水很低的(de)干氣體(ti)，濕式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)主要處理含水較(jiao)高(gao)乃至飽和的(de)濕氣體(ti)。在對集塵(chen)(chen)(chen)板(ban)/管(guan)上(shang)(shang)捕集到的(de)粉塵(chen)(chen)(chen)清除(chu)(chu)方式上(shang)(shang)WESP與DESP有(you)較(jiao)大區(qu)別，干式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)一(yi)般采用機械(xie)振打或(huo)聲(sheng)波清灰(hui)(hui)等(deng)方式清除(chu)(chu)電(dian)(dian)(dian)極上(shang)(shang)的(de)積灰(hui)(hui)，而(er)濕式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)則采用定期沖洗(xi)的(de)方式，使粉塵(chen)(chen)(chen)隨(sui)著沖刷液的(de)流動而(er)清除(chu)(chu)。
