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)電除塵器主要(yao)有兩種結構形(xing)式(shi)，一種是使用(yong)耐腐蝕導(dao)(dao)(dao)電材(cai)料（可以為導(dao)(dao)(dao)電性能(neng)優良的(de)(de)的(de)(de)非(fei)金(jin)屬(shu)材(cai)料或具有耐腐蝕特性的(de)(de)金(jin)屬(shu)材(cai)料）做集塵極，另一種是用(yong)通過噴水(shui)(shui)或溢流水(shui)(shui)形(xing)成導(dao)(dao)(dao)電水(shui)(shui)膜，利用(yong)不導(dao)(dao)(dao)電的(de)(de)非(fei)金(jin)屬(shu)材(cai)料做集塵極。

收塵(chen)原理

濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)和與(yu)干(gan)(gan)式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的收(shou)塵(chen)(chen)(chen)(chen)(chen)原(yuan)理(li)相同，都是靠高(gao)壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的作(zuo)用(yong)(yong)下到達集(ji)(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)板/管(guan)。干(gan)(gan)式(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)(chen)器(qi)主(zhu)要(yao)處(chu)理(li)含水很(hen)低的干(gan)(gan)氣體，濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)主(zhu)要(yao)處(chu)理(li)含水較(jiao)高(gao)乃(nai)至飽和的濕(shi)氣體。在對集(ji)(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)板/管(guan)上捕集(ji)(ji)(ji)到的粉塵(chen)(chen)(chen)(chen)(chen)清除(chu)(chu)(chu)方式(shi)上WESP與(yu)DESP有較(jiao)大區別，干(gan)(gan)式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)一般采用(yong)(yong)機(ji)械振打或聲波清灰(hui)等(deng)方式(shi)清除(chu)(chu)(chu)電(dian)(dian)(dian)極上的積灰(hui)，而(er)濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)則采用(yong)(yong)定(ding)期沖(chong)洗的方式(shi)，使(shi)粉塵(chen)(chen)(chen)(chen)(chen)隨著沖(chong)刷液的流動而(er)清除(chu)(chu)(chu)。
