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。

臥式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)凈(jing)化(hua)工(gong)作(zuo)上要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩個系(xi)統來(lai)完成的(de)(de)，當(dang)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)流(liu)分(fen)(fen)布板(ban)以及折流(liu)板(ban)的(de)(de)調(diao)整后，使氣(qi)(qi)流(liu)能較均勻(yun)地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫(heng)斷面擴大(da)的(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)流(liu)速度(du)迅速降(jiang)低，其(qi)中(zhong)有(you)些較重的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速度(du)而沉降(jiang)下(xia)來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用(yong)下(xia)趨向本(ben)設備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備(bei)采用(yong)負(fu)高(gao)壓制)和(he)陰極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子分(fen)(fen)別(bie)沉積(ji)在(zai)(zai)(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設備(bei)陰陽(yang)極(ji)(ji)(ji)振(zhen)打系(xi)統的(de)(de)振(zhen)打，使沉積(ji)在(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)(ren)集灰(hui)斗 通過排灰(hui)裝置放出，回(hui)收有(you)物料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)。

工作(zuo)原(yuan)理(li)

靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)工作原理是利(li)用(yong)高(gao)(gao)壓電(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用(yong)下與氣(qi)流分離。負(fu)極(ji)由不(bu)同斷面形(xing)狀(zhuang)(zhuang)的(de)(de)金屬導線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾(ji)何形(xing)狀(zhuang)(zhuang)的(de)(de)金屬板制(zhi)成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構(gou)造和煙(yan)氣(qi)流速(su)等(deng)三個(ge)因素的(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效(xiao)率有(you)直(zhi)接(jie)的(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)(chen)粒難以(yi)保持在(zai)集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其(qi)重返氣(qi)流。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過高(gao)(gao)，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)局(ju)部擊穿和放電(dian)(dian)(dian)現象。這(zhe)些情(qing)況都會造成(cheng)除塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電除(chu)塵器的基(ji)本原理(li)是利用電力捕(bu)集煙氣(qi)中的粉(fen)(fen)塵，主要包括(kuo)以(yi)下四個相互(hu)有關的物理(li)過程: (1) 氣(qi)體的電離(li)。(2) 粉(fen)(fen)塵的荷電。(3) 荷電粉(fen)(fen)塵向電極移動。(4) 荷電粉(fen)(fen)塵的捕(bu)集。
