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)除塵(chen)(chen)器(qi)是(shi)以靜電(dian)(dian)(dian)凈(jing)化(hua)法來收(shou)捕(bu)廢(fei)氣(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)，它(ta)的(de)(de)凈(jing)化(hua)工作(zuo)上(shang)要是(shi)依靠(kao)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉(chen)(chen)淀兩個系統來完成(cheng)的(de)(de)，當含塵(chen)(chen)氣(qi)體(ti)(ti)進人(ren)氣(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)體(ti)(ti)受到(dao)氣(qi)流(liu)分布板以及折流(liu)板的(de)(de)調整后，使(shi)氣(qi)流(liu)能(neng)較均勻地進人(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷面擴(kuo)大(da)的(de)(de)作(zuo)用(yong)下，氣(qi)流(liu)速度迅速降(jiang)低，其中(zhong)有些較重的(de)(de)塵(chen)(chen)粒(li)便(bian)失(shi)去(qu)速度而(er)沉(chen)(chen)降(jiang)下來。進人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)氣(qi)體(ti)(ti)由(you)于(yu)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)高(gao)(gao)壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)體(ti)(ti)中(zhong)存在(zai)(zai)(zai)大(da)量(liang)的(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與(yu)進人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下趨向(xiang)本(ben)設(she)備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)備(bei)采用(yong)負高(gao)(gao)壓(ya)制)和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分別沉(chen)(chen)積在(zai)(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設(she)備(bei)陰陽(yang)極(ji)(ji)(ji)振(zhen)(zhen)打系統的(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)(chen)積在(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)(chen)振(zhen)(zhen)落(luo)，進人(ren)集灰斗 通過排灰裝置放出，回收(shou)有物料，被(bei))凈(jing)化(hua)的(de)(de)氣(qi)體(ti)(ti)排入大(da)氣(qi)。

工作(zuo)原理(li)

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)(de)工作原(yuan)理是利用(yong)高壓(ya)電(dian)(dian)(dian)(dian)場使(shi)煙(yan)(yan)氣(qi)(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)離，氣(qi)(qi)(qi)流(liu)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場作用(yong)下與氣(qi)(qi)(qi)流(liu)分離。負極(ji)(ji)由不(bu)同斷面形狀的(de)(de)(de)(de)金屬(shu)導線制成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何(he)形狀的(de)(de)(de)(de)金屬(shu)板制成，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)(de)性能受粉塵(chen)(chen)性質(zhi)、設備構造和煙(yan)(yan)氣(qi)(qi)(qi)流(liu)速等三個(ge)因素(su)的(de)(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指標，它對除(chu)塵(chen)(chen)效率有直接的(de)(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)粒難以保持在(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣(qi)(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過高，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在(zai)(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部擊穿和放電(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造成除(chu)塵(chen)(chen)效率下降。

電(dian)除塵器的基本原理是利用電(dian)力捕(bu)集(ji)(ji)煙氣中的粉塵，主要包括以(yi)下四個(ge)相互(hu)有關的物(wu)理過(guo)程: (1) 氣體的電(dian)離。(2) 粉塵的荷(he)電(dian)。(3) 荷(he)電(dian)粉塵向電(dian)極移動。(4) 荷(he)電(dian)粉塵的捕(bu)集(ji)(ji)。
