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(zhu)要有(you)兩種(zhong)結構形式，一種(zhong)是使用(yong)耐腐蝕(shi)導電(dian)(dian)材(cai)料（可以(yi)為導電(dian)(dian)性(xing)能優良(liang)的(de)(de)的(de)(de)非(fei)金屬(shu)(shu)材(cai)料或(huo)具有(you)耐腐蝕(shi)特性(xing)的(de)(de)金屬(shu)(shu)材(cai)料）做集塵極，另一種(zhong)是用(yong)通過噴水或(huo)溢流水形成導電(dian)(dian)水膜，利用(yong)不導電(dian)(dian)的(de)(de)非(fei)金屬(shu)(shu)材(cai)料做集塵極。

收塵原理(li)

濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)和(he)與干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)作用下到達集塵(chen)(chen)(chen)板(ban)/管(guan)。干式(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主要處(chu)理含水(shui)很低的(de)(de)干氣(qi)體(ti)，濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)主要處(chu)理含水(shui)較高乃至(zhi)飽和(he)的(de)(de)濕(shi)氣(qi)體(ti)。在(zai)對集塵(chen)(chen)(chen)板(ban)/管(guan)上捕集到的(de)(de)粉(fen)塵(chen)(chen)(chen)清除(chu)(chu)(chu)方式(shi)(shi)(shi)上WESP與DESP有較大區別，干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)一般采用機械(xie)振打或(huo)聲波清灰等方式(shi)(shi)(shi)清除(chu)(chu)(chu)電(dian)(dian)(dian)極上的(de)(de)積灰，而濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)則采用定期沖(chong)洗的(de)(de)方式(shi)(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)隨(sui)著沖(chong)刷液的(de)(de)流動而清除(chu)(chu)(chu)。
