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)除塵(chen)器主(zhu)要有兩種結構(gou)形(xing)式，一種是使用耐腐蝕導(dao)電(dian)材料(liao)（可以(yi)為(wei)導(dao)電(dian)性能優良的的非(fei)金屬(shu)材料(liao)或(huo)具有耐腐蝕特性的金屬(shu)材料(liao)）做集塵(chen)極(ji)，另一種是用通(tong)過噴水(shui)或(huo)溢流水(shui)形(xing)成導(dao)電(dian)水(shui)膜，利用不導(dao)電(dian)的非(fei)金屬(shu)材料(liao)做集塵(chen)極(ji)。

收(shou)塵原理

濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)和與(yu)干(gan)式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)收塵(chen)(chen)原(yuan)理(li)相同，都(dou)是(shi)靠高(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉塵(chen)(chen)在電(dian)(dian)(dian)(dian)場力的(de)作用(yong)下到達集塵(chen)(chen)板(ban)/管。干(gan)式(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)器(qi)主要處理(li)含水(shui)很低的(de)干(gan)氣體(ti)，濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)主要處理(li)含水(shui)較(jiao)高(gao)乃至飽和的(de)濕(shi)(shi)氣體(ti)。在對集塵(chen)(chen)板(ban)/管上捕集到的(de)粉塵(chen)(chen)清(qing)除方式(shi)上WESP與(yu)DESP有較(jiao)大(da)區別(bie)，干(gan)式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)一般采用(yong)機械振打(da)或聲波(bo)清(qing)灰(hui)等(deng)方式(shi)清(qing)除電(dian)(dian)(dian)(dian)極(ji)上的(de)積灰(hui)，而濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)則采用(yong)定期(qi)沖(chong)洗的(de)方式(shi)，使粉塵(chen)(chen)隨著沖(chong)刷(shua)液的(de)流動(dong)而清(qing)除。
