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(dian)除塵器主要有(you)(you)兩(liang)種結構形(xing)式(shi)，一種是(shi)使用(yong)(yong)耐(nai)腐蝕(shi)導(dao)(dao)電(dian)材料(liao)（可以為導(dao)(dao)電(dian)性(xing)能優(you)良的(de)的(de)非金屬(shu)(shu)材料(liao)或具有(you)(you)耐(nai)腐蝕(shi)特性(xing)的(de)金屬(shu)(shu)材料(liao)）做(zuo)集塵極，另一種是(shi)用(yong)(yong)通過噴水或溢流水形(xing)成導(dao)(dao)電(dian)水膜，利用(yong)(yong)不導(dao)(dao)電(dian)的(de)非金屬(shu)(shu)材料(liao)做(zuo)集塵極。

收塵原理

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和與(yu)干式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)收塵(chen)(chen)(chen)(chen)原理相同，都是靠(kao)高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場(chang)力(li)的(de)作用(yong)下到(dao)達集(ji)塵(chen)(chen)(chen)(chen)板(ban)/管。干式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主(zhu)要(yao)處理含(han)(han)水很低(di)的(de)干氣(qi)體，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主(zhu)要(yao)處理含(han)(han)水較高(gao)乃至飽和的(de)濕氣(qi)體。在對集(ji)塵(chen)(chen)(chen)(chen)板(ban)/管上(shang)(shang)(shang)捕(bu)集(ji)到(dao)的(de)粉(fen)塵(chen)(chen)(chen)(chen)清除(chu)(chu)方(fang)式(shi)(shi)上(shang)(shang)(shang)WESP與(yu)DESP有較大區別(bie)，干式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)一般采用(yong)機械(xie)振打(da)或聲波清灰等方(fang)式(shi)(shi)清除(chu)(chu)電(dian)(dian)(dian)極(ji)上(shang)(shang)(shang)的(de)積灰，而濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)則采用(yong)定期沖(chong)洗的(de)方(fang)式(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)隨(sui)著沖(chong)刷液的(de)流(liu)動而清除(chu)(chu)。
