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)式靜(jing)電(dian)(dian)(dian)除塵(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)凈化(hua)法來收捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉塵(chen)，它的(de)(de)凈化(hua)工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)暈(yun)極和沉(chen)(chen)淀兩(liang)個(ge)系統來完成的(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)(qi)刺(ci)叭時，含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流能較均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷(duan)面擴(kuo)大(da)(da)的(de)(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)(qi)流速(su)度迅速(su)降低，其中(zhong)有(you)些較重的(de)(de)塵(chen)粒(li)便失去速(su)度而(er)沉(chen)(chen)降下來。進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈(yun)極通(tong)人(ren)高壓(ya)直流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極附近產(chan)生(sheng)電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存(cun)在(zai)大(da)(da)量的(de)(de)電(dian)(dian)(dian)子和離子，這(zhe)些電(dian)(dian)(dian)子和離子與進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉塵(chen)結合起來，使(shi)塵(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作(zuo)用下趨(qu)向本設(she)備(bei)(bei)陽極(正(zheng)極、本設(she)備(bei)(bei)采用負高壓(ya)制)和陰(yin)極(負極) ， 釋放出(chu)電(dian)(dian)(dian)子分(fen)別沉(chen)(chen)積在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)極上，通(tong)過(guo)設(she)備(bei)(bei)陰(yin)陽極振(zhen)打(da)(da)系統的(de)(de)振(zhen)打(da)(da)，使(shi)沉(chen)(chen)積在(zai)陰(yin)陽電(dian)(dian)(dian)極上的(de)(de)粉塵(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗(dou) 通(tong)過(guo)排灰裝置(zhi)放出(chu)，回收有(you)物料，被(bei))凈化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入(ru)大(da)(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工(gong)作原(yuan)理是利(li)用(yong)(yong)高(gao)(gao)壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用(yong)(yong)下(xia)與氣(qi)流分(fen)離。負(fu)極(ji)由(you)不同斷面形(xing)狀(zhuang)的(de)金屬(shu)導(dao)線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何(he)形(xing)狀(zhuang)的(de)金屬(shu)板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設(she)備構造和(he)煙氣(qi)流速等三個因(yin)素(su)的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)效率有直接的(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以保(bao)持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重(zhong)返氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)(gao)，到(dao)達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些情(qing)況都會(hui)造成(cheng)除塵(chen)(chen)(chen)效率下(xia)降(jiang)。

電除塵(chen)(chen)器的(de)(de)基本原理是(shi)利用電力(li)捕集煙(yan)氣中(zhong)的(de)(de)粉塵(chen)(chen)，主(zhu)要包(bao)括以下(xia)四個相(xiang)互有關(guan)的(de)(de)物理過(guo)程(cheng): (1) 氣體(ti)的(de)(de)電離。(2) 粉塵(chen)(chen)的(de)(de)荷(he)電。(3) 荷(he)電粉塵(chen)(chen)向電極(ji)移動。(4) 荷(he)電粉塵(chen)(chen)的(de)(de)捕集。
