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)(dian)除塵器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉塵，它的(de)(de)(de)(de)凈化(hua)(hua)工作(zuo)上(shang)要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)沉(chen)淀兩個(ge)系(xi)統(tong)(tong)來(lai)完成的(de)(de)(de)(de)，當(dang)含(han)(han)塵氣(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)刺叭(ba)時(shi)，含(han)(han)塵氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流能較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)(zai)橫斷面擴大(da)(da)的(de)(de)(de)(de)作(zuo)用(yong)下(xia)(xia)，氣(qi)(qi)(qi)流速(su)度迅速(su)降低(di)，其中有些較重(zhong)的(de)(de)(de)(de)塵粒(li)便失去(qu)速(su)度而沉(chen)降下(xia)(xia)來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含(han)(han)塵氣(qi)(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通人(ren)(ren)高(gao)壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)(zai)(zai)大(da)(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子與(yu)進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉塵結(jie)合起(qi)來(lai)，使(shi)塵粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵粒(li)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)(xia)趨向本設備(bei)陽(yang)(yang)(yang)極(ji)(正極(ji)、本設備(bei)采用(yong)負(fu)高(gao)壓(ya)制(zhi))和(he)陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子分(fen)別(bie)沉(chen)積在(zai)(zai)(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過(guo)設備(bei)陰陽(yang)(yang)(yang)極(ji)振打(da)系(xi)統(tong)(tong)的(de)(de)(de)(de)振打(da)，使(shi)沉(chen)積在(zai)(zai)(zai)陰陽(yang)(yang)(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉塵振落，進人(ren)(ren)集灰斗 通過(guo)排(pai)灰裝置放出，回收有物料(liao)，被)凈化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大(da)(da)氣(qi)(qi)(qi)。

工作原理(li)

靜電除塵(chen)(chen)(chen)(chen)(chen)器的(de)工作(zuo)(zuo)原理是(shi)利(li)用高壓電場使(shi)煙(yan)氣發(fa)生電離，氣流中的(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電在電場作(zuo)(zuo)用下與氣流分離。負極(ji)由(you)不同斷面形(xing)狀(zhuang)的(de)金(jin)屬導線制成，叫(jiao)(jiao)放(fang)電電極(ji)。正極(ji)由(you)不同幾何形(xing)狀(zhuang)的(de)金(jin)屬板制成，叫(jiao)(jiao)集塵(chen)(chen)(chen)(chen)(chen)電極(ji)。靜電除塵(chen)(chen)(chen)(chen)(chen)器的(de)性(xing)(xing)(xing)能(neng)受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)(xing)(xing)質、設備構造(zao)和煙(yan)氣流速(su)等三(san)個(ge)因(yin)素的(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)比電阻是(shi)評價導電性(xing)(xing)(xing)的(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有直接的(de)影(ying)響。比電阻過低(di)，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)(chen)電極(ji)上，致使(shi)其重返氣流。比電阻過高，到達集塵(chen)(chen)(chen)(chen)(chen)電極(ji)的(de)塵(chen)(chen)(chen)(chen)(chen)粒電荷不易放(fang)出(chu)，在塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成電壓梯度(du)會產(chan)生局部擊穿(chuan)和放(fang)電現(xian)象。這(zhe)些(xie)情(qing)況(kuang)都會造(zao)成除塵(chen)(chen)(chen)(chen)(chen)效率下降(jiang)。

電(dian)除塵(chen)(chen)器的(de)(de)基本原理(li)是利用(yong)電(dian)力捕集煙氣中的(de)(de)粉(fen)(fen)塵(chen)(chen)，主要包括(kuo)以下四個相互有關的(de)(de)物理(li)過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉(fen)(fen)塵(chen)(chen)向(xiang)電(dian)極(ji)移動。(4) 荷(he)(he)電(dian)粉(fen)(fen)塵(chen)(chen)的(de)(de)捕集。
