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)(dian)(dian)除塵(chen)器(qi)主要有兩種結(jie)構形式，一種是使(shi)用耐腐(fu)蝕(shi)(shi)導電(dian)(dian)(dian)(dian)材(cai)料(liao)(liao)（可(ke)以為導電(dian)(dian)(dian)(dian)性(xing)(xing)能(neng)優(you)良的(de)的(de)非金屬(shu)材(cai)料(liao)(liao)或具有耐腐(fu)蝕(shi)(shi)特(te)性(xing)(xing)的(de)金屬(shu)材(cai)料(liao)(liao)）做集塵(chen)極(ji)，另(ling)一種是用通過(guo)噴水(shui)(shui)或溢流水(shui)(shui)形成導電(dian)(dian)(dian)(dian)水(shui)(shui)膜，利用不導電(dian)(dian)(dian)(dian)的(de)非金屬(shu)材(cai)料(liao)(liao)做集塵(chen)極(ji)。

收塵原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)和與干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)的(de)(de)收塵(chen)(chen)原理相同，都是靠(kao)高(gao)壓電(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)使(shi)得(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作用(yong)(yong)下(xia)到(dao)(dao)達集塵(chen)(chen)板(ban)/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)(qi)主要處(chu)理含(han)水很(hen)低的(de)(de)干(gan)氣(qi)體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)主要處(chu)理含(han)水較高(gao)乃至飽和的(de)(de)濕(shi)氣(qi)體。在對(dui)集塵(chen)(chen)板(ban)/管(guan)上(shang)捕(bu)集到(dao)(dao)的(de)(de)粉塵(chen)(chen)清(qing)除(chu)方(fang)式(shi)(shi)上(shang)WESP與DESP有較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)一(yi)般采用(yong)(yong)機械振(zhen)打或(huo)聲波清(qing)灰(hui)等方(fang)式(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)極上(shang)的(de)(de)積(ji)灰(hui)，而(er)濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)則采用(yong)(yong)定期沖(chong)洗的(de)(de)方(fang)式(shi)(shi)，使(shi)粉塵(chen)(chen)隨(sui)著沖(chong)刷液的(de)(de)流動而(er)清(qing)除(chu)。
