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(shi)電除塵(chen)器主要有兩種(zhong)結構形(xing)式(shi)，一種(zhong)是使用耐腐蝕導電材(cai)料（可(ke)以為導電性能優良的的非(fei)金(jin)屬(shu)材(cai)料或(huo)具有耐腐蝕特性的金(jin)屬(shu)材(cai)料）做集塵(chen)極，另(ling)一種(zhong)是用通過噴(pen)水或(huo)溢(yi)流水形(xing)成導電水膜，利(li)用不導電的非(fei)金(jin)屬(shu)材(cai)料做集塵(chen)極。

收塵原理

濕式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)和與(yu)干式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)收塵(chen)(chen)原理相同(tong)，都是靠高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后(hou)的(de)粉塵(chen)(chen)在(zai)電(dian)(dian)(dian)場(chang)力的(de)作用下到(dao)(dao)達集塵(chen)(chen)板(ban)/管(guan)(guan)。干式電(dian)(dian)(dian)收塵(chen)(chen)器(qi)主(zhu)要處(chu)理含水很低的(de)干氣體，濕式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)主(zhu)要處(chu)理含水較高(gao)乃至飽和的(de)濕氣體。在(zai)對(dui)集塵(chen)(chen)板(ban)/管(guan)(guan)上(shang)捕集到(dao)(dao)的(de)粉塵(chen)(chen)清(qing)除(chu)(chu)方式上(shang)WESP與(yu)DESP有(you)較大區(qu)別(bie)，干式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)一(yi)般(ban)采(cai)用機械振打或聲波清(qing)灰等方式清(qing)除(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)積(ji)灰，而(er)(er)濕式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)則采(cai)用定期沖(chong)(chong)洗的(de)方式，使(shi)粉塵(chen)(chen)隨著沖(chong)(chong)刷液(ye)的(de)流動而(er)(er)清(qing)除(chu)(chu)。
