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)除塵器主要有兩(liang)種(zhong)結構形式，一種(zhong)是使用耐腐(fu)蝕導電(dian)(dian)材料（可以為導電(dian)(dian)性能優良的(de)(de)的(de)(de)非金屬(shu)材料或具有耐腐(fu)蝕特性的(de)(de)金屬(shu)材料）做集(ji)塵極，另(ling)一種(zhong)是用通過噴水(shui)或溢流水(shui)形成導電(dian)(dian)水(shui)膜，利用不導電(dian)(dian)的(de)(de)非金屬(shu)材料做集(ji)塵極。

濕式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)和(he)(he)與(yu)干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)的(de)收(shou)塵(chen)原理相(xiang)同(tong)，都是靠(kao)高(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉塵(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉塵(chen)在電(dian)(dian)(dian)(dian)場力的(de)作用(yong)下(xia)到達集(ji)塵(chen)板/管(guan)。干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)收(shou)塵(chen)器(qi)主要處(chu)理含(han)水(shui)很低(di)的(de)干(gan)氣(qi)體(ti)，濕式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)主要處(chu)理含(han)水(shui)較高(gao)乃至飽和(he)(he)的(de)濕氣(qi)體(ti)。在對集(ji)塵(chen)板/管(guan)上捕集(ji)到的(de)粉塵(chen)清(qing)除方(fang)式(shi)(shi)(shi)上WESP與(yu)DESP有較大(da)區別，干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)一般采用(yong)機械振打或(huo)聲(sheng)波清(qing)灰(hui)等方(fang)式(shi)(shi)(shi)清(qing)除電(dian)(dian)(dian)(dian)極上的(de)積灰(hui)，而濕式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)則采用(yong)定期沖(chong)洗的(de)方(fang)式(shi)(shi)(shi)，使粉塵(chen)隨著沖(chong)刷液的(de)流動而清(qing)除。
