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(zhu)要(yao)有兩(liang)種結構形(xing)式，一(yi)種是使用耐(nai)腐蝕導(dao)(dao)電(dian)材料(liao)（可以為導(dao)(dao)電(dian)性能優良的(de)(de)的(de)(de)非金屬(shu)材料(liao)或(huo)具有耐(nai)腐蝕特性的(de)(de)金屬(shu)材料(liao)）做(zuo)集塵極，另一(yi)種是用通過(guo)噴(pen)水或(huo)溢流水形(xing)成(cheng)導(dao)(dao)電(dian)水膜，利用不導(dao)(dao)電(dian)的(de)(de)非金屬(shu)材料(liao)做(zuo)集塵極。

收塵原理

濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和與干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)收(shou)(shou)塵(chen)(chen)(chen)(chen)原理相同(tong)，都是靠高壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)作(zuo)用下到(dao)達集(ji)(ji)塵(chen)(chen)(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)(dian)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處理含水(shui)很低的(de)干氣(qi)體，濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處理含水(shui)較(jiao)高乃至飽和的(de)濕氣(qi)體。在對集(ji)(ji)塵(chen)(chen)(chen)(chen)板/管(guan)上(shang)捕集(ji)(ji)到(dao)的(de)粉塵(chen)(chen)(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)上(shang)WESP與DESP有較(jiao)大區別，干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)一般采用機械振打或聲波(bo)清(qing)灰等方式(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)積(ji)灰，而濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)則采用定期(qi)沖(chong)洗的(de)方式(shi)，使粉塵(chen)(chen)(chen)(chen)隨著沖(chong)刷液的(de)流動而清(qing)除(chu)(chu)(chu)。
