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(chen)器主(zhu)要有兩(liang)種(zhong)結構形式，一種(zhong)是(shi)使用(yong)耐腐蝕導(dao)(dao)電(dian)材(cai)(cai)料（可以為(wei)導(dao)(dao)電(dian)性能優良的的非金屬材(cai)(cai)料或(huo)具有耐腐蝕特性的金屬材(cai)(cai)料）做集塵(chen)極，另一種(zhong)是(shi)用(yong)通過噴水或(huo)溢流水形成(cheng)導(dao)(dao)電(dian)水膜，利用(yong)不導(dao)(dao)電(dian)的非金屬材(cai)(cai)料做集塵(chen)極。

收塵原理

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)和與干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)的(de)(de)收塵(chen)(chen)原理相(xiang)同，都是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)作用(yong)(yong)下(xia)到達(da)集(ji)塵(chen)(chen)板/管。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)(qi)主要處理含水很低的(de)(de)干(gan)氣體(ti)，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)主要處理含水較高乃(nai)至飽和的(de)(de)濕氣體(ti)。在(zai)對集(ji)塵(chen)(chen)板/管上(shang)捕集(ji)到的(de)(de)粉(fen)塵(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)(shi)上(shang)WESP與DESP有較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)一般(ban)采(cai)用(yong)(yong)機(ji)械振打或聲(sheng)波清(qing)灰等方式(shi)(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)積灰，而(er)濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)則采(cai)用(yong)(yong)定期沖(chong)洗的(de)(de)方式(shi)(shi)，使粉(fen)塵(chen)(chen)隨著(zhu)沖(chong)刷液的(de)(de)流動而(er)清(qing)除(chu)(chu)(chu)。
