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。

濕式電除塵(chen)器主要(yao)有兩種結構(gou)形(xing)式，一種是使用耐(nai)腐蝕(shi)導(dao)電材(cai)(cai)料(liao)（可以為導(dao)電性能優良的(de)的(de)非金(jin)屬(shu)材(cai)(cai)料(liao)或具有耐(nai)腐蝕(shi)特性的(de)金(jin)屬(shu)材(cai)(cai)料(liao)）做(zuo)集(ji)塵(chen)極，另一種是用通過(guo)噴(pen)水或溢流水形(xing)成導(dao)電水膜(mo)，利(li)用不導(dao)電的(de)非金(jin)屬(shu)材(cai)(cai)料(liao)做(zuo)集(ji)塵(chen)極。

收塵(chen)原(yuan)理

濕(shi)式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和與干式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的收(shou)塵(chen)(chen)(chen)(chen)原理(li)相同，都是靠高(gao)壓(ya)電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后的粉(fen)(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力的作(zuo)用下(xia)到(dao)達集塵(chen)(chen)(chen)(chen)板/管(guan)。干式電(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主(zhu)要處理(li)含水(shui)很低的干氣(qi)(qi)體(ti)，濕(shi)式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主(zhu)要處理(li)含水(shui)較(jiao)高(gao)乃至(zhi)飽和的濕(shi)氣(qi)(qi)體(ti)。在對(dui)集塵(chen)(chen)(chen)(chen)板/管(guan)上捕集到(dao)的粉(fen)(fen)塵(chen)(chen)(chen)(chen)清除(chu)方式上WESP與DESP有較(jiao)大(da)區別，干式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)一般采用機械振打(da)或聲波清灰等方式清除(chu)電(dian)(dian)(dian)(dian)極上的積灰，而濕(shi)式電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)則(ze)采用定(ding)期沖洗的方式，使粉(fen)(fen)塵(chen)(chen)(chen)(chen)隨(sui)著沖刷液的流動而清除(chu)。
