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(qi)主要有(you)兩(liang)種結構形式，一(yi)種是(shi)使用耐(nai)腐(fu)(fu)蝕(shi)導電(dian)(dian)材料（可以為導電(dian)(dian)性(xing)能優良的的非金(jin)屬(shu)材料或具有(you)耐(nai)腐(fu)(fu)蝕(shi)特性(xing)的金(jin)屬(shu)材料）做集塵(chen)極，另一(yi)種是(shi)用通過噴水(shui)或溢(yi)流水(shui)形成(cheng)導電(dian)(dian)水(shui)膜，利用不導電(dian)(dian)的非金(jin)屬(shu)材料做集塵(chen)極。

收塵原理

濕式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)和(he)與(yu)干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)的(de)(de)(de)收塵(chen)(chen)原理相同，都(dou)是靠高(gao)壓電(dian)(dian)暈放電(dian)(dian)使得粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)，荷(he)電(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下到達集(ji)塵(chen)(chen)板/管。干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)收塵(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)(chu)理含(han)(han)水很低的(de)(de)(de)干(gan)(gan)氣體，濕式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)(chu)理含(han)(han)水較高(gao)乃至飽和(he)的(de)(de)(de)濕氣體。在對集(ji)塵(chen)(chen)板/管上捕集(ji)到的(de)(de)(de)粉(fen)塵(chen)(chen)清(qing)(qing)除(chu)(chu)方式(shi)(shi)(shi)上WESP與(yu)DESP有較大區別，干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)一般采(cai)用(yong)機(ji)械振(zhen)打或(huo)聲波清(qing)(qing)灰等方式(shi)(shi)(shi)清(qing)(qing)除(chu)(chu)電(dian)(dian)極上的(de)(de)(de)積灰，而濕式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)則采(cai)用(yong)定期沖(chong)洗的(de)(de)(de)方式(shi)(shi)(shi)，使粉(fen)塵(chen)(chen)隨(sui)著沖(chong)刷(shua)液的(de)(de)(de)流動而清(qing)(qing)除(chu)(chu)。
