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)除塵器主要有(you)兩種結構形(xing)式，一種是(shi)使用(yong)(yong)耐腐(fu)蝕導電(dian)(dian)材料（可以為導電(dian)(dian)性(xing)能優(you)良的(de)的(de)非金屬(shu)材料或具(ju)有(you)耐腐(fu)蝕特性(xing)的(de)金屬(shu)材料）做集(ji)塵極，另一種是(shi)用(yong)(yong)通過噴水(shui)或溢流水(shui)形(xing)成導電(dian)(dian)水(shui)膜，利用(yong)(yong)不導電(dian)(dian)的(de)非金屬(shu)材料做集(ji)塵極。

收塵原理(li)

濕式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)和與(yu)干(gan)式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)收(shou)塵(chen)(chen)(chen)原理相同(tong)，都是靠高(gao)壓電(dian)(dian)暈(yun)放電(dian)(dian)使(shi)得粉(fen)(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的(de)粉(fen)(fen)(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)場(chang)力的(de)作用(yong)下到(dao)達集塵(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)收(shou)塵(chen)(chen)(chen)器(qi)主要處理含水(shui)很(hen)低(di)的(de)干(gan)氣(qi)(qi)體(ti)，濕式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)主要處理含水(shui)較高(gao)乃至飽(bao)和的(de)濕氣(qi)(qi)體(ti)。在(zai)對集塵(chen)(chen)(chen)板/管(guan)上(shang)(shang)捕集到(dao)的(de)粉(fen)(fen)(fen)塵(chen)(chen)(chen)清除(chu)方式(shi)(shi)上(shang)(shang)WESP與(yu)DESP有(you)較大(da)區別，干(gan)式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)一般采用(yong)機(ji)械振打或聲波清灰等方式(shi)(shi)清除(chu)電(dian)(dian)極上(shang)(shang)的(de)積灰，而濕式(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)則采用(yong)定期沖洗的(de)方式(shi)(shi)，使(shi)粉(fen)(fen)(fen)塵(chen)(chen)(chen)隨著沖刷液的(de)流動(dong)而清除(chu)。
