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(shi)式電(dian)除(chu)塵器主要有(you)(you)兩種(zhong)結構形式，一種(zhong)是使用(yong)(yong)耐腐蝕導電(dian)材(cai)料(liao)（可以為導電(dian)性能優良的(de)的(de)非金屬(shu)材(cai)料(liao)或具有(you)(you)耐腐蝕特性的(de)金屬(shu)材(cai)料(liao)）做(zuo)集塵極，另一種(zhong)是用(yong)(yong)通過噴水(shui)或溢流水(shui)形成導電(dian)水(shui)膜，利用(yong)(yong)不導電(dian)的(de)非金屬(shu)材(cai)料(liao)做(zuo)集塵極。

收(shou)塵原理

濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)和與(yu)(yu)干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)的收(shou)塵(chen)(chen)(chen)原理(li)相同(tong)，都是靠高(gao)壓電(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)(dian)后的粉塵(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)(dian)場力的作用(yong)下到(dao)(dao)達集塵(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處理(li)含水很(hen)低的干(gan)氣體(ti)，濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處理(li)含水較高(gao)乃至飽和的濕(shi)(shi)氣體(ti)。在對集塵(chen)(chen)(chen)板/管(guan)上捕集到(dao)(dao)的粉塵(chen)(chen)(chen)清(qing)除(chu)(chu)方式(shi)(shi)(shi)上WESP與(yu)(yu)DESP有較大區別，干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)一(yi)般采(cai)用(yong)機械振(zhen)打或聲(sheng)波清(qing)灰等(deng)方式(shi)(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)(dian)(dian)極上的積灰，而(er)(er)濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)則(ze)采(cai)用(yong)定期(qi)沖(chong)洗的方式(shi)(shi)(shi)，使粉塵(chen)(chen)(chen)隨著沖(chong)刷(shua)液(ye)的流動(dong)而(er)(er)清(qing)除(chu)(chu)。
