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)除塵器主要有兩種結構形式，一(yi)種是使用耐腐(fu)蝕(shi)導電(dian)材(cai)料（可(ke)以為導電(dian)性能優良(liang)的(de)的(de)非(fei)(fei)金屬材(cai)料或具有耐腐(fu)蝕(shi)特(te)性的(de)金屬材(cai)料）做集塵極，另(ling)一(yi)種是用通過噴水(shui)或溢流水(shui)形成(cheng)導電(dian)水(shui)膜，利用不(bu)導電(dian)的(de)非(fei)(fei)金屬材(cai)料做集塵極。

收塵(chen)原理

濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器和與干式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器的(de)收塵(chen)(chen)原理相同，都是(shi)靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)(shi)得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)場(chang)力的(de)作用下到(dao)達集(ji)塵(chen)(chen)板(ban)/管。干式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器主(zhu)要處理含水很低的(de)干氣體，濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器主(zhu)要處理含水較(jiao)高乃至飽和的(de)濕(shi)氣體。在對(dui)集(ji)塵(chen)(chen)板(ban)/管上(shang)捕集(ji)到(dao)的(de)粉(fen)塵(chen)(chen)清(qing)除方(fang)式(shi)(shi)(shi)(shi)上(shang)WESP與DESP有(you)較(jiao)大區別(bie)，干式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器一般采用機械振打或聲波(bo)清(qing)灰(hui)等方(fang)式(shi)(shi)(shi)(shi)清(qing)除電(dian)(dian)(dian)極上(shang)的(de)積灰(hui)，而濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器則采用定(ding)期(qi)沖(chong)(chong)洗的(de)方(fang)式(shi)(shi)(shi)(shi)，使(shi)(shi)粉(fen)塵(chen)(chen)隨著(zhu)沖(chong)(chong)刷液的(de)流動而清(qing)除。
