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(shi)靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)是以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收捕廢(fei)氣(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈(jing)化工作上(shang)要是依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩個(ge)系(xi)統來完成的(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)進人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)受到(dao)氣(qi)(qi)流(liu)(liu)(liu)(liu)分布(bu)板以及折流(liu)(liu)(liu)(liu)板的(de)(de)(de)(de)(de)(de)調整(zheng)后(hou)，使(shi)氣(qi)(qi)流(liu)(liu)(liu)(liu)能(neng)較均勻地(di)進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)流(liu)(liu)(liu)(liu)速度迅速降(jiang)低，其(qi)中有些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去速度而(er)沉降(jiang)下(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓(ya)直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)中存(cun)在(zai)(zai)(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)與(yu)進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)(de)(de)作用(yong)下(xia)趨(qu)向(xiang)本(ben)設(she)備(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)設(she)備(bei)采用(yong)負高壓(ya)制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別(bie)沉積在(zai)(zai)(zai)相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過(guo)設(she)備(bei)陰陽極(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)(de)(de)振(zhen)打，使(shi)沉積在(zai)(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落(luo)，進人(ren)集灰(hui)(hui)斗 通過(guo)排(pai)(pai)灰(hui)(hui)裝置放出，回收有物料，被(bei))凈(jing)化的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)排(pai)(pai)入大(da)氣(qi)(qi)。

工作(zuo)原理(li)

靜電(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)工作(zuo)原理是(shi)(shi)利用(yong)高(gao)壓電(dian)場使煙(yan)氣(qi)(qi)(qi)發(fa)生電(dian)離(li)，氣(qi)(qi)(qi)流中的(de)粉塵(chen)(chen)(chen)(chen)荷(he)電(dian)在(zai)電(dian)場作(zuo)用(yong)下與氣(qi)(qi)(qi)流分離(li)。負(fu)極(ji)由(you)不(bu)(bu)同斷面形狀的(de)金屬導線(xian)制成，叫放(fang)(fang)電(dian)電(dian)極(ji)。正極(ji)由(you)不(bu)(bu)同幾何(he)形狀的(de)金屬板制成，叫集塵(chen)(chen)(chen)(chen)電(dian)極(ji)。靜電(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)性能(neng)受粉塵(chen)(chen)(chen)(chen)性質、設(she)備(bei)構造和(he)煙(yan)氣(qi)(qi)(qi)流速(su)等(deng)三(san)個因素(su)的(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)比電(dian)阻(zu)是(shi)(shi)評價導電(dian)性的(de)指標(biao)，它對除塵(chen)(chen)(chen)(chen)效(xiao)率有直接的(de)影響。比電(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)極(ji)上，致使其重返(fan)氣(qi)(qi)(qi)流。比電(dian)阻(zu)過高(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)荷(he)不(bu)(bu)易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層之間形成電(dian)壓梯度會(hui)產生局部(bu)擊穿和(he)放(fang)(fang)電(dian)現象(xiang)。這些情況都會(hui)造成除塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵(chen)器的基本原理(li)是(shi)利用電(dian)(dian)力(li)捕集(ji)煙氣中的粉(fen)(fen)(fen)(fen)塵(chen)，主要包括(kuo)以下四個相互有(you)關(guan)的物理(li)過程: (1) 氣體的電(dian)(dian)離。(2) 粉(fen)(fen)(fen)(fen)塵(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)(fen)(fen)塵(chen)向(xiang)電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)(fen)(fen)(fen)塵(chen)的捕集(ji)。
