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)除塵(chen)器主要(yao)有(you)(you)兩種結構形(xing)式，一種是使用耐(nai)腐蝕(shi)導(dao)電(dian)(dian)材(cai)(cai)料(liao)（可以為導(dao)電(dian)(dian)性能優良的的非金屬材(cai)(cai)料(liao)或(huo)具有(you)(you)耐(nai)腐蝕(shi)特性的金屬材(cai)(cai)料(liao)）做集(ji)塵(chen)極，另(ling)一種是用通過(guo)噴水或(huo)溢流水形(xing)成導(dao)電(dian)(dian)水膜(mo)，利用不導(dao)電(dian)(dian)的非金屬材(cai)(cai)料(liao)做集(ji)塵(chen)極。

收(shou)塵(chen)原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)和(he)與干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)的收塵(chen)(chen)原理相同，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)后的粉塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的作用下到達(da)集塵(chen)(chen)板/管。干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)(qi)主要處理含(han)水很(hen)低的干(gan)(gan)氣體(ti)，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)主要處理含(han)水較(jiao)高(gao)乃至飽和(he)的濕(shi)氣體(ti)。在(zai)對集塵(chen)(chen)板/管上(shang)捕集到的粉塵(chen)(chen)清(qing)(qing)除(chu)(chu)方(fang)式(shi)(shi)上(shang)WESP與DESP有較(jiao)大區別，干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)一般采(cai)用機械振打(da)或聲波清(qing)(qing)灰(hui)(hui)等方(fang)式(shi)(shi)清(qing)(qing)除(chu)(chu)電(dian)(dian)(dian)極上(shang)的積灰(hui)(hui)，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)則采(cai)用定期(qi)沖(chong)洗的方(fang)式(shi)(shi)，使(shi)粉塵(chen)(chen)隨(sui)著(zhu)沖(chong)刷液(ye)的流動而清(qing)(qing)除(chu)(chu)。
