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。

濕式電除塵器(qi)主(zhu)要有兩種(zhong)結構形式，一種(zhong)是(shi)使用(yong)(yong)耐(nai)(nai)腐蝕(shi)導(dao)(dao)電材料(liao)（可以為導(dao)(dao)電性(xing)能優良的的非金(jin)屬(shu)(shu)材料(liao)或具有耐(nai)(nai)腐蝕(shi)特性(xing)的金(jin)屬(shu)(shu)材料(liao)）做(zuo)集(ji)塵極，另一種(zhong)是(shi)用(yong)(yong)通過噴水(shui)或溢流(liu)水(shui)形成導(dao)(dao)電水(shui)膜，利用(yong)(yong)不導(dao)(dao)電的非金(jin)屬(shu)(shu)材料(liao)做(zuo)集(ji)塵極。

收塵原理

濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)和(he)與干(gan)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)的(de)(de)(de)收塵(chen)(chen)原理(li)相同(tong)，都是靠高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)(de)粉塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下到(dao)達集(ji)(ji)塵(chen)(chen)板/管。干(gan)式(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)主要處理(li)含(han)水(shui)很低(di)的(de)(de)(de)干(gan)氣體，濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)主要處理(li)含(han)水(shui)較高(gao)乃(nai)至飽和(he)的(de)(de)(de)濕氣體。在對集(ji)(ji)塵(chen)(chen)板/管上(shang)捕集(ji)(ji)到(dao)的(de)(de)(de)粉塵(chen)(chen)清(qing)(qing)除(chu)(chu)方式(shi)上(shang)WESP與DESP有較大區別，干(gan)式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)一般(ban)采用(yong)機械振打或聲波清(qing)(qing)灰等方式(shi)清(qing)(qing)除(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)(de)(de)積(ji)灰，而濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)則采用(yong)定期沖(chong)洗的(de)(de)(de)方式(shi)，使(shi)粉塵(chen)(chen)隨著(zhu)沖(chong)刷液的(de)(de)(de)流動而清(qing)(qing)除(chu)(chu)。
