XWD型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(shi)靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢(fei)氣(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)凈化工(gong)作上要是(shi)(shi)依靠電(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀兩(liang)個(ge)系統(tong)來(lai)完成的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)進人氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流(liu)分(fen)布(bu)板以及(ji)折(zhe)流(liu)板的(de)(de)(de)調整(zheng)后，使氣(qi)(qi)流(liu)能較均勻(yun)地進人電(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴大的(de)(de)(de)作用(yong)(yong)下，氣(qi)(qi)流(liu)速度迅(xun)速降(jiang)低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去速度而沉降(jiang)下來(lai)。進人電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)暈極(ji)通人高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中存在大量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)與進人電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合起來(lai)，使塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用(yong)(yong)下趨向(xiang)本(ben)設備陽(yang)極(ji)(正(zheng)極(ji)、本(ben)設備采用(yong)(yong)負(fu)高(gao)壓制)和(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉積(ji)在相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通過(guo)設備陰(yin)陽(yang)極(ji)振(zhen)(zhen)打系統(tong)的(de)(de)(de)振(zhen)(zhen)打，使沉積(ji)在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)(zhen)落，進人集灰斗 通過(guo)排灰裝置放(fang)出，回收有物料(liao)，被)凈化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排入大氣(qi)(qi)。

工(gong)作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的工作原理是利用(yong)高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用(yong)下(xia)與(yu)氣流(liu)分離。負極(ji)(ji)由不(bu)同(tong)斷(duan)面(mian)形(xing)(xing)狀的金屬(shu)導線(xian)制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同(tong)幾何形(xing)(xing)狀的金屬(shu)板制成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設備(bei)構(gou)造和煙(yan)氣流(liu)速等三個因素的影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)(xing)的指標，它對除(chu)(chu)塵(chen)(chen)(chen)效率有直接的影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致(zhi)使其(qi)重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯(ti)度會(hui)(hui)產(chan)生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效率下(xia)降。

電(dian)除塵(chen)(chen)(chen)器的基本原理(li)是利用電(dian)力(li)捕(bu)集(ji)煙(yan)氣(qi)中的粉塵(chen)(chen)(chen)，主要包括以下四個相互有關(guan)的物理(li)過程(cheng): (1) 氣(qi)體(ti)(ti)的電(dian)離。(2) 粉塵(chen)(chen)(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)(chen)(chen)向(xiang)電(dian)極移動。(4) 荷(he)電(dian)粉塵(chen)(chen)(chen)的捕(bu)集(ji)。
