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)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)，它的(de)(de)凈化(hua)(hua)工作(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)(he)沉(chen)(chen)淀(dian)兩個(ge)系統來(lai)完成的(de)(de)，當含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)受到(dao)氣(qi)(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)流(liu)能較均(jun)勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)(da)的(de)(de)作(zuo)(zuo)用下(xia)，氣(qi)(qi)(qi)流(liu)速(su)度(du)迅速(su)降低，其中(zhong)有些(xie)較重的(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)便失去(qu)速(su)度(du)而沉(chen)(chen)降下(xia)來(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)(ren)高(gao)(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)大(da)(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)作(zuo)(zuo)用下(xia)趨向本(ben)設(she)備(bei)(bei)陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備(bei)(bei)采用負高(gao)(gao)壓制)和(he)(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分(fen)別沉(chen)(chen)積(ji)在(zai)相(xiang)應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備(bei)(bei)陰(yin)陽(yang)(yang)極(ji)(ji)振(zhen)打系統的(de)(de)振(zhen)打，使(shi)沉(chen)(chen)積(ji)在(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)(ren)集灰斗 通過排灰裝置放出，回收有物料，被(bei))凈化(hua)(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排入大(da)(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)(de)(de)(de)工作(zuo)原理是(shi)(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)(de)(de)粉塵(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作(zuo)用下與氣(qi)流分離。負極由不同斷面形狀(zhuang)的(de)(de)(de)(de)(de)金屬(shu)(shu)導(dao)線(xian)制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不同幾何形狀(zhuang)的(de)(de)(de)(de)(de)金屬(shu)(shu)板制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)(de)(de)(de)性能受粉塵(chen)(chen)性質、設(she)備構(gou)造(zao)和煙氣(qi)流速等三個(ge)因素(su)的(de)(de)(de)(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是(shi)(shi)評價導(dao)電(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)效率有直接的(de)(de)(de)(de)(de)影響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致(zhi)使其重返氣(qi)流。比電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)(he)不易放(fang)出，在(zai)塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生局部擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器的基本原理是利用電(dian)(dian)力捕(bu)集煙氣(qi)(qi)中的粉(fen)塵(chen)，主要(yao)包括以下四個相互有關的物理過程(cheng): (1) 氣(qi)(qi)體的電(dian)(dian)離。(2) 粉(fen)塵(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)向(xiang)電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)的捕(bu)集。
