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)(chen)器主要(yao)有兩種結構形式，一(yi)種是使用(yong)(yong)耐腐蝕(shi)導電(dian)(dian)材料（可以(yi)為導電(dian)(dian)性(xing)能優良的的非金(jin)屬材料或(huo)具有耐腐蝕(shi)特(te)性(xing)的金(jin)屬材料）做(zuo)集塵(chen)(chen)極(ji)，另一(yi)種是用(yong)(yong)通過噴水或(huo)溢(yi)流水形成導電(dian)(dian)水膜(mo)，利用(yong)(yong)不(bu)導電(dian)(dian)的非金(jin)屬材料做(zuo)集塵(chen)(chen)極(ji)。

收塵原理

濕(shi)式電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和與(yu)(yu)干(gan)(gan)式電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)收(shou)(shou)塵(chen)(chen)(chen)(chen)(chen)原理相同，都(dou)是靠高(gao)壓電(dian)(dian)暈(yun)放電(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)場力的(de)(de)作用(yong)下(xia)到達集塵(chen)(chen)(chen)(chen)(chen)板(ban)/管。干(gan)(gan)式電(dian)(dian)收(shou)(shou)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)理含(han)水(shui)很低的(de)(de)干(gan)(gan)氣體，濕(shi)式電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)理含(han)水(shui)較高(gao)乃至飽(bao)和的(de)(de)濕(shi)氣體。在對集塵(chen)(chen)(chen)(chen)(chen)板(ban)/管上(shang)捕集到的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)清(qing)除(chu)(chu)方式上(shang)WESP與(yu)(yu)DESP有較大區別，干(gan)(gan)式電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)一般采用(yong)機械振(zhen)打或聲波清(qing)灰(hui)等(deng)方式清(qing)除(chu)(chu)電(dian)(dian)極(ji)上(shang)的(de)(de)積灰(hui)，而濕(shi)式電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)則采用(yong)定期沖(chong)洗(xi)的(de)(de)方式，使粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)隨著沖(chong)刷(shua)液的(de)(de)流動而清(qing)除(chu)(chu)。
