臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥式靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)(lai)收(shou)捕(bu)廢氣(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)凈(jing)(jing)化(hua)工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)(he)(he)沉(chen)淀兩個系統來(lai)(lai)完(wan)成的(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)人(ren)(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)受到(dao)氣(qi)流(liu)(liu)(liu)分布板(ban)以(yi)及折流(liu)(liu)(liu)板(ban)的(de)(de)調(diao)整后(hou)，使氣(qi)流(liu)(liu)(liu)能較均勻(yun)地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)。在(zai)橫斷面擴大的(de)(de)作(zuo)用(yong)下(xia)，氣(qi)流(liu)(liu)(liu)速(su)度(du)迅速(su)降(jiang)低，其中(zhong)有些(xie)較重的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)(li)便(bian)失去速(su)度(du)而(er)沉(chen)降(jiang)下(xia)來(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)(ren)高壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)體(ti)(ti)(ti)中(zhong)存在(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)(he)離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)(he)離(li)子(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結(jie)合起來(lai)(lai)，使塵(chen)(chen)(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)(li)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)力的(de)(de)作(zuo)用(yong)下(xia)趨向本設(she)備陽(yang)(yang)極(ji)(正(zheng)極(ji)、本設(she)備采用(yong)負(fu)高壓制(zhi))和(he)(he)(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設(she)備陰(yin)陽(yang)(yang)極(ji)振(zhen)打系統的(de)(de)振(zhen)打，使沉(chen)積在(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)(ren)集(ji)灰斗 通(tong)過排灰裝置(zhi)放(fang)(fang)出，回收(shou)有物(wu)料(liao)，被)凈(jing)(jing)化(hua)的(de)(de)氣(qi)體(ti)(ti)(ti)排入(ru)大氣(qi)。

工作(zuo)原理(li)

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的工作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣流(liu)分(fen)離。負(fu)極由(you)不(bu)同(tong)斷面形狀的金屬導線(xian)制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極。正極由(you)不(bu)同(tong)幾(ji)何形狀的金屬板制成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的性能受粉塵(chen)(chen)(chen)性質、設(she)備構造和(he)煙氣流(liu)速等(deng)三個因素(su)的影響。粉塵(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)(dian)(dian)性的指標，它(ta)對(dui)除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)有直(zhi)接的影響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極上，致使其重(zhong)返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到(dao)達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出，在塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些(xie)情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)除塵器的基本原理(li)是利用電(dian)力捕集(ji)(ji)煙氣中(zhong)的粉塵，主要(yao)包括以下四個相(xiang)互有關的物理(li)過程: (1) 氣體的電(dian)離。(2) 粉塵的荷(he)電(dian)。(3) 荷(he)電(dian)粉塵向電(dian)極移動。(4) 荷(he)電(dian)粉塵的捕集(ji)(ji)。
