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。

臥式靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化(hua)法(fa)來(lai)收捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工作(zuo)上(shang)要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和(he)沉淀兩個(ge)系(xi)(xi)統來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)刺(ci)叭(ba)時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受(shou)到(dao)氣(qi)(qi)流(liu)分布(bu)板以及(ji)折(zhe)流(liu)板的(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)流(liu)能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在橫(heng)斷面擴(kuo)大的(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)速(su)(su)度(du)迅速(su)(su)降(jiang)低，其中有些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便(bian)失去速(su)(su)度(du)而沉降(jiang)下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通(tong)人(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附(fu)近(jin)產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)體(ti)中存在大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子，這些(xie)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下趨向本(ben)設(she)備陽極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本(ben)設(she)備采用(yong)負高(gao)壓制)和(he)陰(yin)極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)子分別沉積在相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)，通(tong)過(guo)設(she)備陰(yin)陽極(ji)(ji)(ji)(ji)(ji)振(zhen)打系(xi)(xi)統的(de)(de)(de)(de)振(zhen)打，使(shi)沉積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振(zhen)落，進(jin)人(ren)集灰(hui)斗 通(tong)過(guo)排灰(hui)裝置放出(chu)，回收有物料，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作原理

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工(gong)作原理是利用高(gao)壓(ya)電(dian)(dian)場使煙氣發(fa)生(sheng)(sheng)電(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作用下與氣流(liu)分離。負極(ji)由不同斷(duan)面形(xing)(xing)狀的(de)金屬導(dao)線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)。正(zheng)極(ji)由不同幾何形(xing)(xing)狀的(de)金屬板制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性能受粉塵(chen)(chen)(chen)(chen)性質、設備構造和煙氣流(liu)速等(deng)三個因(yin)素的(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)阻(zu)是評(ping)價導(dao)電(dian)(dian)性的(de)指(zhi)標(biao)，它對(dui)除(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)影響。比(bi)電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒(li)難以保持(chi)在集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重(zhong)返氣流(liu)。比(bi)電(dian)(dian)阻(zu)過(guo)高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)壓(ya)梯度會產生(sheng)(sheng)局部擊穿和放(fang)電(dian)(dian)現(xian)象。這些(xie)情況都(dou)會造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)除塵器的(de)(de)基(ji)本原理是利(li)用電(dian)力捕(bu)集(ji)煙氣(qi)中的(de)(de)粉(fen)塵，主要(yao)包括以下四個相互有關的(de)(de)物理過程: (1) 氣(qi)體的(de)(de)電(dian)離。(2) 粉(fen)塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向電(dian)極(ji)移動(dong)。(4) 荷電(dian)粉(fen)塵的(de)(de)捕(bu)集(ji)。
