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(shi)電(dian)(dian)除塵器主要有(you)兩(liang)種結(jie)構形式(shi)，一種是使用耐腐蝕(shi)導(dao)電(dian)(dian)材料(liao)（可以為導(dao)電(dian)(dian)性(xing)能優良(liang)的的非(fei)金屬材料(liao)或(huo)具有(you)耐腐蝕(shi)特性(xing)的金屬材料(liao)）做(zuo)集塵極，另一種是用通過噴(pen)水或(huo)溢流水形成(cheng)導(dao)電(dian)(dian)水膜，利用不導(dao)電(dian)(dian)的非(fei)金屬材料(liao)做(zuo)集塵極。

收塵(chen)原理

濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)和(he)與(yu)干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)的(de)收塵(chen)(chen)原(yuan)理(li)相同(tong)，都是靠高(gao)壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后(hou)的(de)粉塵(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)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)主(zhu)要處理(li)含(han)水(shui)很低(di)的(de)干氣(qi)體(ti)(ti)(ti)，濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)主(zhu)要處理(li)含(han)水(shui)較高(gao)乃至(zhi)飽(bao)和(he)的(de)濕氣(qi)體(ti)(ti)(ti)。在對集(ji)塵(chen)(chen)板(ban)/管上(shang)(shang)捕集(ji)到(dao)的(de)粉塵(chen)(chen)清除(chu)(chu)(chu)方(fang)(fang)式(shi)上(shang)(shang)WESP與(yu)DESP有較大區別，干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)一般采用機械振打(da)或聲波(bo)清灰等方(fang)(fang)式(shi)清除(chu)(chu)(chu)電(dian)(dian)(dian)極上(shang)(shang)的(de)積灰，而濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)則采用定期沖洗(xi)的(de)方(fang)(fang)式(shi)，使粉塵(chen)(chen)隨著沖刷液的(de)流動而清除(chu)(chu)(chu)。
