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(shi)式(shi)(shi)電除塵器主(zhu)要有兩種(zhong)結構形式(shi)(shi)，一種(zhong)是使(shi)用耐腐蝕(shi)導(dao)電材(cai)(cai)料（可以為導(dao)電性能(neng)優良的的非金(jin)屬材(cai)(cai)料或(huo)具有耐腐蝕(shi)特(te)性的金(jin)屬材(cai)(cai)料）做集塵極，另一種(zhong)是用通過噴水或(huo)溢流水形成導(dao)電水膜，利(li)用不導(dao)電的非金(jin)屬材(cai)(cai)料做集塵極。

收塵(chen)原理

濕(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)和與干(gan)(gan)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)收塵(chen)(chen)(chen)原理相同，都是(shi)靠高壓(ya)電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后(hou)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)(yong)下(xia)到達集(ji)塵(chen)(chen)(chen)板/管(guan)。干(gan)(gan)式(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主要處理含(han)水很低的(de)(de)(de)干(gan)(gan)氣體，濕(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)主要處理含(han)水較(jiao)高乃至飽和的(de)(de)(de)濕(shi)氣體。在(zai)(zai)對集(ji)塵(chen)(chen)(chen)板/管(guan)上(shang)捕集(ji)到的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)清除(chu)(chu)(chu)方(fang)式(shi)上(shang)WESP與DESP有較(jiao)大區別，干(gan)(gan)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)一般采(cai)用(yong)(yong)機械振(zhen)打或聲波(bo)清灰等(deng)方(fang)式(shi)清除(chu)(chu)(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)積灰，而濕(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)則采(cai)用(yong)(yong)定期沖(chong)洗(xi)的(de)(de)(de)方(fang)式(shi)，使粉(fen)塵(chen)(chen)(chen)隨著(zhu)沖(chong)刷液的(de)(de)(de)流動而清除(chu)(chu)(chu)。
