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(shi)電除塵器主(zhu)要有兩種(zhong)結構形式(shi)，一(yi)(yi)種(zhong)是(shi)使用耐腐蝕導電材(cai)料(liao)（可以為導電性(xing)(xing)能優良(liang)的(de)的(de)非金屬材(cai)料(liao)或具有耐腐蝕特性(xing)(xing)的(de)金屬材(cai)料(liao)）做(zuo)集塵極(ji)，另一(yi)(yi)種(zhong)是(shi)用通過噴水(shui)或溢流水(shui)形成導電水(shui)膜，利(li)用不導電的(de)非金屬材(cai)料(liao)做(zuo)集塵極(ji)。

收(shou)塵(chen)原理

濕式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)和與干(gan)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)的(de)收塵(chen)(chen)原理相同，都(dou)是(shi)靠(kao)高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)(dian)使(shi)得(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)后(hou)的(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作用下到達集(ji)塵(chen)(chen)板(ban)/管(guan)。干(gan)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)(qi)主要處理含水很低的(de)干(gan)氣(qi)體(ti)，濕式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)主要處理含水較(jiao)高(gao)乃至飽和的(de)濕氣(qi)體(ti)。在對集(ji)塵(chen)(chen)板(ban)/管(guan)上(shang)(shang)捕集(ji)到的(de)粉(fen)塵(chen)(chen)清(qing)除(chu)(chu)方(fang)式(shi)上(shang)(shang)WESP與DESP有較(jiao)大區別，干(gan)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)一般采用機(ji)械振(zhen)打或聲波清(qing)灰等方(fang)式(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)(shang)的(de)積灰，而濕式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)則采用定期沖(chong)(chong)洗的(de)方(fang)式(shi)，使(shi)粉(fen)塵(chen)(chen)隨著(zhu)沖(chong)(chong)刷液的(de)流(liu)動(dong)而清(qing)除(chu)(chu)。
