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(chu)塵器主(zhu)要有兩種(zhong)結(jie)構形式，一種(zhong)是使用耐腐蝕(shi)導(dao)(dao)電(dian)(dian)材(cai)料（可以(yi)為(wei)導(dao)(dao)電(dian)(dian)性(xing)能優良的的非(fei)金屬材(cai)料或(huo)具有耐腐蝕(shi)特性(xing)的金屬材(cai)料）做集塵極，另一種(zhong)是用通(tong)過(guo)噴水(shui)或(huo)溢流水(shui)形成(cheng)導(dao)(dao)電(dian)(dian)水(shui)膜，利用不導(dao)(dao)電(dian)(dian)的非(fei)金屬材(cai)料做集塵極。

收塵原理

濕(shi)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)和與干式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)收塵(chen)(chen)(chen)(chen)原(yuan)理相(xiang)同，都是(shi)靠高壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力的(de)作用下(xia)到達集(ji)(ji)塵(chen)(chen)(chen)(chen)板(ban)/管。干式電(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器(qi)主(zhu)(zhu)要(yao)處理含水很低的(de)干氣體，濕(shi)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)主(zhu)(zhu)要(yao)處理含水較高乃至(zhi)飽和的(de)濕(shi)氣體。在對集(ji)(ji)塵(chen)(chen)(chen)(chen)板(ban)/管上(shang)捕集(ji)(ji)到的(de)粉(fen)塵(chen)(chen)(chen)(chen)清除方(fang)式上(shang)WESP與DESP有(you)較大區別，干式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)一般采(cai)用機械振打或聲波清灰(hui)等方(fang)式清除電(dian)(dian)(dian)(dian)極上(shang)的(de)積灰(hui)，而濕(shi)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)則采(cai)用定期(qi)沖(chong)洗的(de)方(fang)式，使粉(fen)塵(chen)(chen)(chen)(chen)隨著(zhu)沖(chong)刷液的(de)流(liu)動而清除。
