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)(dian)(dian)(dian)除塵(chen)器主要有兩種結構形式，一(yi)種是(shi)使用(yong)耐(nai)(nai)腐(fu)蝕(shi)導電(dian)(dian)(dian)(dian)材(cai)料(liao)（可以為導電(dian)(dian)(dian)(dian)性能(neng)優(you)良的的非金(jin)屬材(cai)料(liao)或具有耐(nai)(nai)腐(fu)蝕(shi)特性的金(jin)屬材(cai)料(liao)）做(zuo)集塵(chen)極，另一(yi)種是(shi)用(yong)通過(guo)噴水或溢(yi)流水形成(cheng)導電(dian)(dian)(dian)(dian)水膜(mo)，利用(yong)不導電(dian)(dian)(dian)(dian)的非金(jin)屬材(cai)料(liao)做(zuo)集塵(chen)極。

收塵原理

濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)和與干(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)收(shou)塵(chen)(chen)(chen)原(yuan)理(li)相同，都是靠高(gao)壓電(dian)(dian)暈放電(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后(hou)的(de)(de)粉塵(chen)(chen)(chen)在電(dian)(dian)場力(li)的(de)(de)作用(yong)下到達集(ji)塵(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)收(shou)塵(chen)(chen)(chen)器(qi)(qi)主要(yao)處(chu)理(li)含水很低的(de)(de)干(gan)氣體(ti)，濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)主要(yao)處(chu)理(li)含水較高(gao)乃至飽和的(de)(de)濕氣體(ti)。在對(dui)集(ji)塵(chen)(chen)(chen)板/管(guan)上捕(bu)集(ji)到的(de)(de)粉塵(chen)(chen)(chen)清(qing)除(chu)(chu)方式(shi)(shi)上WESP與DESP有(you)較大區別，干(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)一般(ban)采用(yong)機械振(zhen)打或聲波清(qing)灰等方式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)極(ji)上的(de)(de)積灰，而(er)濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)則采用(yong)定期沖洗的(de)(de)方式(shi)(shi)，使(shi)粉塵(chen)(chen)(chen)隨著沖刷液的(de)(de)流動(dong)而(er)清(qing)除(chu)(chu)。
