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)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器是以靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收(shou)捕(bu)廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)粉塵(chen)，它的(de)(de)凈化工(gong)作上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)和(he)沉(chen)淀兩個系(xi)統來(lai)完(wan)成的(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體進(jin)人(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭(ba)時，含(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)(qi)流(liu)分(fen)布(bu)板以及折流(liu)板的(de)(de)調整后，使氣(qi)(qi)(qi)(qi)(qi)流(liu)能(neng)較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴大(da)的(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有(you)些(xie)較重(zhong)的(de)(de)塵(chen)粒便失(shi)去速(su)度而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)通(tong)(tong)人(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)現象，使氣(qi)(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體中存(cun)在大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)結合起(qi)來(lai)，使塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用(yong)下趨向本設備(bei)(bei)陽(yang)極(ji)(正(zheng)極(ji)、本設備(bei)(bei)采用(yong)負(fu)高(gao)壓(ya)制(zhi))和(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積(ji)在相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)(tong)過(guo)設備(bei)(bei)陰(yin)陽(yang)極(ji)振(zhen)(zhen)(zhen)打系(xi)統的(de)(de)振(zhen)(zhen)(zhen)打，使沉(chen)積(ji)在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)粉塵(chen)振(zhen)(zhen)(zhen)落，進(jin)人(ren)集灰(hui)斗 通(tong)(tong)過(guo)排灰(hui)裝置放(fang)出，回收(shou)有(you)物料，被)凈化的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體排入(ru)大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)的(de)(de)(de)工作原理是利(li)用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)場使煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)(de)粉塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場作用下(xia)與(yu)氣流(liu)分離(li)。負極(ji)由不同斷面形(xing)狀的(de)(de)(de)金(jin)屬導(dao)線制成(cheng)，叫(jiao)(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾(ji)何形(xing)狀的(de)(de)(de)金(jin)屬板制成(cheng)，叫(jiao)(jiao)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)的(de)(de)(de)性能受粉塵(chen)性質、設備(bei)構造和(he)煙氣流(liu)速等(deng)三個因素(su)的(de)(de)(de)影響(xiang)(xiang)。粉塵(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它(ta)對除(chu)(chu)塵(chen)效率有直接的(de)(de)(de)影響(xiang)(xiang)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)低(di)，塵(chen)粒(li)難以保持(chi)在(zai)(zai)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣流(liu)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)高(gao)，到達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在(zai)(zai)塵(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生(sheng)局部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情(qing)況都會造成(cheng)除(chu)(chu)塵(chen)效率下(xia)降。

電除塵器(qi)的基本(ben)原理(li)(li)是利用電力捕集煙氣中的粉(fen)塵，主要(yao)包括以下四個相互有關的物理(li)(li)過程: (1) 氣體的電離。(2) 粉(fen)塵的荷(he)電。(3) 荷(he)電粉(fen)塵向電極移動。(4) 荷(he)電粉(fen)塵的捕集。
