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。

臥式靜電(dian)(dian)(dian)除塵器是(shi)以靜電(dian)(dian)(dian)凈化(hua)法(fa)來收(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵，它的(de)(de)凈化(hua)工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉(chen)淀兩個(ge)系統來完成的(de)(de)，當(dang)含(han)塵氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)(qi)(qi)(qi)流(liu)分布板以及折(zhe)流(liu)板的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)人電(dian)(dian)(dian)場。在(zai)橫斷面擴大的(de)(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速度(du)迅(xun)速降(jiang)低，其中(zhong)有(you)(you)些較(jiao)重(zhong)的(de)(de)塵粒便失去速度(du)而(er)沉(chen)降(jiang)下來。進(jin)人電(dian)(dian)(dian)場的(de)(de)含(han)塵氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人高(gao)壓直流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大量的(de)(de)電(dian)(dian)(dian)子和(he)離(li)(li)子，這些電(dian)(dian)(dian)子和(he)離(li)(li)子與進(jin)人電(dian)(dian)(dian)場的(de)(de)粉(fen)塵結合起來，使(shi)塵粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用(yong)下趨向(xiang)本設(she)備(bei)(bei)陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)(bei)采用(yong)負高(gao)壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分別沉(chen)積在(zai)相(xiang)應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設(she)備(bei)(bei)陰陽(yang)(yang)極(ji)(ji)振打系統的(de)(de)振打，使(shi)沉(chen)積在(zai)陰陽(yang)(yang)電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉(fen)塵振落，進(jin)人集灰(hui)斗 通(tong)過排灰(hui)裝(zhuang)置(zhi)放出，回(hui)收(shou)有(you)(you)物料，被)凈化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)(qi)。

工作原(yuan)理(li)

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)工(gong)作(zuo)原理是利用(yong)高壓電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)離(li)(li)，氣(qi)流中的(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作(zuo)用(yong)下(xia)與氣(qi)流分(fen)離(li)(li)。負極(ji)(ji)由(you)(you)不(bu)(bu)同(tong)斷面形(xing)狀(zhuang)的(de)金屬(shu)(shu)導線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)(you)不(bu)(bu)同(tong)幾何形(xing)狀(zhuang)的(de)金屬(shu)(shu)板制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和煙氣(qi)流速(su)等(deng)三個因素的(de)影響。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)效率有直接的(de)影響。比電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流。比電(dian)(dian)(dian)(dian)阻過(guo)高，到(dao)達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出(chu)，在塵(chen)(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯(ti)度會(hui)產(chan)生局部擊穿和放電(dian)(dian)(dian)(dian)現象。這些(xie)情況(kuang)都(dou)會(hui)造成(cheng)除塵(chen)(chen)效率下(xia)降。

電除塵(chen)器的(de)基本(ben)原理(li)是利用電力捕(bu)集(ji)煙氣(qi)中的(de)粉(fen)(fen)塵(chen)，主(zhu)要包(bao)括以下四個相互有關的(de)物理(li)過程: (1) 氣(qi)體的(de)電離。(2) 粉(fen)(fen)塵(chen)的(de)荷(he)電。(3) 荷(he)電粉(fen)(fen)塵(chen)向電極移動。(4) 荷(he)電粉(fen)(fen)塵(chen)的(de)捕(bu)集(ji)。
