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(wo)式(shi)靜電(dian)(dian)(dian)(dian)(dian)除塵器(qi)是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收(shou)捕廢氣中(zhong)的(de)(de)(de)(de)(de)粉(fen)(fen)塵，它的(de)(de)(de)(de)(de)凈(jing)化(hua)工作上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉(chen)(chen)(chen)淀兩個系(xi)統來(lai)完成的(de)(de)(de)(de)(de)，當含(han)塵氣體(ti)(ti)(ti)進(jin)(jin)人(ren)(ren)(ren)氣刺叭時，含(han)塵氣體(ti)(ti)(ti)受到氣流分(fen)布板以(yi)及折流板的(de)(de)(de)(de)(de)調整(zheng)后，使氣流能較(jiao)均勻地進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫斷面(mian)擴大的(de)(de)(de)(de)(de)作用(yong)下，氣流速(su)度(du)迅速(su)降(jiang)低，其中(zhong)有些較(jiao)重的(de)(de)(de)(de)(de)塵粒便失去速(su)度(du)而沉(chen)(chen)(chen)降(jiang)下來(lai)。進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含(han)塵氣體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)(tong)人(ren)(ren)(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象(xiang)，使氣體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)(de)氣體(ti)(ti)(ti)中(zhong)存在(zai)(zai)(zai)大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子，這些電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子與進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)(fen)塵結合起(qi)來(lai)，使塵粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作用(yong)下趨向本(ben)(ben)設備陽極(ji)(ji)(正極(ji)(ji)、本(ben)(ben)設備采(cai)用(yong)負(fu)高壓制)和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉(chen)(chen)(chen)積(ji)在(zai)(zai)(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)(tong)過設備陰陽極(ji)(ji)振(zhen)(zhen)(zhen)打系(xi)統的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)打，使沉(chen)(chen)(chen)積(ji)在(zai)(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)(de)粉(fen)(fen)塵振(zhen)(zhen)(zhen)落，進(jin)(jin)人(ren)(ren)(ren)集灰(hui)斗 通(tong)(tong)過排灰(hui)裝置放(fang)出，回收(shou)有物料，被)凈(jing)化(hua)的(de)(de)(de)(de)(de)氣體(ti)(ti)(ti)排入大氣。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)(de)工作(zuo)原理是利用高壓電(dian)(dian)(dian)場使(shi)(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用下與氣(qi)流(liu)分(fen)離(li)。負極(ji)(ji)由(you)不同斷面形狀的(de)(de)(de)(de)(de)金屬導線制成，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形狀的(de)(de)(de)(de)(de)金屬板制成，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備構造和煙氣(qi)流(liu)速等(deng)三個因素的(de)(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)(de)指(zhi)標，它對(dui)除(chu)(chu)塵(chen)(chen)效率有直接的(de)(de)(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)(shi)其重(zhong)返氣(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯度(du)會產生(sheng)局部(bu)擊(ji)穿和放(fang)電(dian)(dian)(dian)現象。這些情(qing)況(kuang)都會造成除(chu)(chu)塵(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)(chen)器的(de)(de)基本(ben)原理(li)是利用電(dian)(dian)力捕(bu)集煙(yan)氣(qi)中的(de)(de)粉(fen)(fen)塵(chen)(chen)，主要包括(kuo)以下四(si)個(ge)相互有(you)關的(de)(de)物理(li)過程: (1) 氣(qi)體的(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)極(ji)移動。(4) 荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)(de)捕(bu)集。
