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)除塵(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)(lai)(lai)收捕(bu)廢(fei)氣(qi)(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)和(he)沉(chen)淀兩個系統來(lai)(lai)(lai)完成的(de)(de)(de)，當含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)體進人(ren)氣(qi)(qi)刺叭時，含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)(de)調(diao)整后，使氣(qi)(qi)流(liu)能較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面(mian)擴大(da)的(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)流(liu)速度迅速降低，其中(zhong)有(you)(you)些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)粒便(bian)失去速度而沉(chen)降下(xia)來(lai)(lai)(lai)。進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)體由(you)于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)通人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)體中(zhong)存在大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離(li)(li)子(zi)(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離(li)(li)子(zi)(zi)(zi)與進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)(lai)(lai)，使塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作(zuo)用下(xia)趨向(xiang)本(ben)設(she)備陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)設(she)備采(cai)用負高壓制)和(he)陰(yin)(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分(fen)別沉(chen)積在相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通過設(she)備陰(yin)(yin)陽(yang)極(ji)(ji)(ji)(ji)振(zhen)打系統的(de)(de)(de)振(zhen)打，使沉(chen)積在陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進人(ren)集(ji)灰斗 通過排灰裝置(zhi)放(fang)出，回(hui)收有(you)(you)物料(liao)，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)體排入大(da)氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)工作原理(li)是利用(yong)高壓(ya)電(dian)(dian)場使煙氣發生電(dian)(dian)離(li)，氣流(liu)中的(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用(yong)下(xia)與氣流(liu)分離(li)。負極(ji)(ji)由不同斷面形(xing)狀的(de)金(jin)(jin)屬導線(xian)制(zhi)成，叫放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形(xing)狀的(de)金(jin)(jin)屬板制(zhi)成，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構(gou)造和(he)(he)煙氣流(liu)速(su)等三個(ge)因(yin)素的(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)性(xing)的(de)指(zhi)標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)影響(xiang)。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持(chi)在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其重返氣流(liu)。比電(dian)(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)(chen)層之間(jian)形(xing)成電(dian)(dian)壓(ya)梯度會產生局部(bu)擊(ji)穿和(he)(he)放電(dian)(dian)現象。這些(xie)情(qing)況都會造成除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)(dian)除(chu)塵(chen)(chen)器的基本原理(li)是利用電(dian)(dian)力捕(bu)(bu)集煙氣中(zhong)的粉(fen)(fen)塵(chen)(chen)，主要包括以(yi)下四個(ge)相互有(you)關的物理(li)過程(cheng): (1) 氣體的電(dian)(dian)離(li)。(2) 粉(fen)(fen)塵(chen)(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)的捕(bu)(bu)集。
