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)式電除塵(chen)器主要有兩種(zhong)結構(gou)形式，一種(zhong)是使(shi)用耐腐(fu)蝕(shi)導電材(cai)(cai)(cai)料(liao)（可(ke)以為導電性能優良的的非金屬(shu)材(cai)(cai)(cai)料(liao)或(huo)具有耐腐(fu)蝕(shi)特性的金屬(shu)材(cai)(cai)(cai)料(liao)）做集塵(chen)極(ji)，另一種(zhong)是用通過噴水(shui)或(huo)溢(yi)流水(shui)形成導電水(shui)膜，利用不導電的非金屬(shu)材(cai)(cai)(cai)料(liao)做集塵(chen)極(ji)。

收塵原理

濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)和(he)與干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)收塵(chen)(chen)(chen)原(yuan)理相同，都是靠高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后(hou)的(de)粉塵(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)作用下到達集塵(chen)(chen)(chen)板(ban)/管。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主(zhu)要處(chu)理含水(shui)很低的(de)干氣體，濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)主(zhu)要處(chu)理含水(shui)較高(gao)乃至飽和(he)的(de)濕氣體。在對集塵(chen)(chen)(chen)板(ban)/管上(shang)捕(bu)集到的(de)粉塵(chen)(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)上(shang)WESP與DESP有較大區別，干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)一(yi)般(ban)采用機械振打(da)或聲波清(qing)灰(hui)等方式(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)積灰(hui)，而(er)濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)則(ze)采用定期沖(chong)(chong)洗的(de)方式(shi)，使(shi)粉塵(chen)(chen)(chen)隨(sui)著沖(chong)(chong)刷液的(de)流(liu)動而(er)清(qing)除(chu)(chu)(chu)。
