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(wo)式(shi)靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)凈(jing)化工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和(he)(he)沉(chen)淀兩個系(xi)統來(lai)完成的(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體進人(ren)氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流分布(bu)板以及折流板的(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)流能(neng)較均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)。在(zai)橫斷面擴(kuo)大(da)的(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)(qi)(qi)流速度(du)(du)迅速降低，其中(zhong)有些較重的(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速度(du)(du)而沉(chen)降下來(lai)。進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)(qi)(qi)(qi)體中(zhong)存在(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子，這些電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子與進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來(lai)，使(shi)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)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)力的(de)作(zuo)用(yong)(yong)下趨(qu)向本(ben)設備(bei)(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)設備(bei)(bei)采用(yong)(yong)負(fu)(fu)高壓制)和(he)(he)陰極(ji)(ji)(負(fu)(fu)極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)相(xiang)應的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過(guo)設備(bei)(bei)陰陽極(ji)(ji)振(zhen)打(da)系(xi)統的(de)振(zhen)打(da)，使(shi)沉(chen)積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)集(ji)灰斗 通過(guo)排灰裝置放(fang)出，回收有物料，被)凈(jing)化的(de)氣(qi)(qi)(qi)(qi)體排入大(da)氣(qi)(qi)(qi)(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)工作原(yuan)理是利用(yong)高壓(ya)電(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)離，氣流中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下(xia)(xia)與氣流分(fen)離。負極(ji)由(you)不同斷面形(xing)狀的(de)(de)金屬(shu)導(dao)線制(zhi)成，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形(xing)狀的(de)(de)金屬(shu)板制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造和(he)煙氣流速等三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)性的(de)(de)指標，它(ta)對除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率(lv)有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其(qi)重返氣流。比(bi)電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)(he)不易放(fang)(fang)出，在塵(chen)(chen)(chen)層(ceng)之間形(xing)成電(dian)(dian)(dian)壓(ya)梯度會(hui)產生局部擊(ji)穿和(he)放(fang)(fang)電(dian)(dian)(dian)現象(xiang)。這些情(qing)況都會(hui)造成除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率(lv)下(xia)(xia)降。

電(dian)(dian)(dian)(dian)除塵器的基本原理是利用電(dian)(dian)(dian)(dian)力捕集(ji)(ji)煙氣中的粉塵，主要包括以下四個相(xiang)互有關的物(wu)理過(guo)程: (1) 氣體的電(dian)(dian)(dian)(dian)離(li)。(2) 粉塵的荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉塵向電(dian)(dian)(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)(dian)(dian)粉塵的捕集(ji)(ji)。
