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(shi)式(shi)電除(chu)塵器主(zhu)要有(you)兩種結構形式(shi)，一(yi)種是使用耐腐蝕導電材(cai)料(liao)(liao)（可以為導電性(xing)能(neng)優良(liang)的(de)的(de)非金(jin)屬(shu)材(cai)料(liao)(liao)或具有(you)耐腐蝕特(te)性(xing)的(de)金(jin)屬(shu)材(cai)料(liao)(liao)）做集(ji)塵極(ji)，另(ling)一(yi)種是用通過噴水或溢流水形成(cheng)導電水膜，利用不導電的(de)非金(jin)屬(shu)材(cai)料(liao)(liao)做集(ji)塵極(ji)。

收塵原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)和與(yu)干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)的收塵(chen)(chen)原理相(xiang)同，都是靠高壓電(dian)(dian)(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)(dian)場力的作用(yong)下(xia)到達(da)集塵(chen)(chen)板(ban)/管(guan)(guan)。干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)收塵(chen)(chen)器(qi)主(zhu)要處理含水(shui)很低的干氣體(ti)，濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)主(zhu)要處理含水(shui)較高乃至飽和的濕(shi)氣體(ti)。在對集塵(chen)(chen)板(ban)/管(guan)(guan)上(shang)捕集到的粉(fen)塵(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)(shi)上(shang)WESP與(yu)DESP有較大區別，干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)一般采用(yong)機械(xie)振打或聲(sheng)波清(qing)灰等方式(shi)(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)(dian)(dian)極上(shang)的積灰，而(er)濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)則采用(yong)定期沖(chong)洗的方式(shi)(shi)，使粉(fen)塵(chen)(chen)隨著(zhu)沖(chong)刷液(ye)的流動而(er)清(qing)除(chu)(chu)(chu)。
