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(chen)器主要有(you)兩種(zhong)結構(gou)形(xing)式，一種(zhong)是使用(yong)耐(nai)(nai)腐蝕(shi)導(dao)(dao)電(dian)(dian)材料（可以為導(dao)(dao)電(dian)(dian)性能(neng)優良的(de)的(de)非(fei)金(jin)屬(shu)材料或具有(you)耐(nai)(nai)腐蝕(shi)特性的(de)金(jin)屬(shu)材料）做集塵(chen)極，另(ling)一種(zhong)是用(yong)通過(guo)噴水或溢流水形(xing)成導(dao)(dao)電(dian)(dian)水膜(mo)，利(li)用(yong)不導(dao)(dao)電(dian)(dian)的(de)非(fei)金(jin)屬(shu)材料做集塵(chen)極。

收塵(chen)原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器和與干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)收(shou)塵(chen)(chen)原理相同(tong)，都是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)粉塵(chen)(chen)在電(dian)(dian)(dian)場力(li)的(de)作用(yong)下(xia)到達(da)集(ji)(ji)塵(chen)(chen)板(ban)/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)器主(zhu)要處理含水很低的(de)干(gan)氣體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器主(zhu)要處理含水較高乃至(zhi)飽(bao)和的(de)濕(shi)氣體。在對集(ji)(ji)塵(chen)(chen)板(ban)/管(guan)上(shang)捕集(ji)(ji)到的(de)粉塵(chen)(chen)清除(chu)方式(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)器一般采(cai)用(yong)機械振打或聲(sheng)波清灰等方式(shi)(shi)清除(chu)電(dian)(dian)(dian)極上(shang)的(de)積(ji)灰，而(er)濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器則采(cai)用(yong)定期沖洗的(de)方式(shi)(shi)，使粉塵(chen)(chen)隨著沖刷液的(de)流(liu)動而(er)清除(chu)。
