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)除(chu)塵(chen)(chen)(chen)器是以靜(jing)(jing)電(dian)(dian)凈(jing)化法來(lai)(lai)收(shou)(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)化工作上要是依(yi)靠電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)和(he)沉(chen)(chen)淀(dian)兩個系統來(lai)(lai)完成的(de)(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體進(jin)人氣(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分(fen)布(bu)板以及(ji)折流(liu)板的(de)(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)流(liu)能(neng)較均勻地進(jin)人電(dian)(dian)場。在(zai)(zai)橫(heng)斷面擴(kuo)大(da)的(de)(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)流(liu)速度(du)迅速降低，其中有些較重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去速度(du)而沉(chen)(chen)降下來(lai)(lai)。進(jin)人電(dian)(dian)場的(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)通(tong)(tong)人高壓直流(liu)電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)附(fu)近產生(sheng)電(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)體電(dian)(dian)離(li)(li)(li)，電(dian)(dian)離(li)(li)(li)后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)體中存在(zai)(zai)大(da)量的(de)(de)(de)(de)(de)電(dian)(dian)子和(he)離(li)(li)(li)子，這些電(dian)(dian)子和(he)離(li)(li)(li)子與(yu)進(jin)人電(dian)(dian)場的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)場力的(de)(de)(de)(de)(de)作用(yong)下趨向本(ben)設備陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)設備采用(yong)負高壓制)和(he)陰(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)子分(fen)別沉(chen)(chen)積(ji)在(zai)(zai)相應(ying)的(de)(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)(tong)過設備陰(yin)陽極(ji)(ji)(ji)(ji)振(zhen)打系統的(de)(de)(de)(de)(de)振(zhen)打，使(shi)沉(chen)(chen)積(ji)在(zai)(zai)陰(yin)陽電(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)人集(ji)灰斗 通(tong)(tong)過排灰裝置放出(chu)，回收(shou)(shou)有物料，被(bei))凈(jing)化的(de)(de)(de)(de)(de)氣(qi)(qi)體排入(ru)大(da)氣(qi)(qi)。

工作原(yuan)理(li)

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)工作原(yuan)理是利用(yong)高壓(ya)電(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用(yong)下(xia)與氣(qi)流(liu)分(fen)離。負(fu)極(ji)(ji)由不同斷面形(xing)(xing)狀的(de)金屬導線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形(xing)(xing)狀的(de)金屬板(ban)制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)性能受粉塵(chen)(chen)性質、設備構(gou)造和煙(yan)氣(qi)流(liu)速等三個因(yin)素的(de)影響(xiang)。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性的(de)指標，它對除(chu)(chu)塵(chen)(chen)效率(lv)有(you)直接(jie)的(de)影響(xiang)。比電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒(li)難以保持(chi)在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返(fan)氣(qi)流(liu)。比電(dian)(dian)(dian)阻(zu)過高，到(dao)達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷(he)不易放出，在(zai)塵(chen)(chen)層之(zhi)間(jian)形(xing)(xing)成(cheng)電(dian)(dian)(dian)壓(ya)梯(ti)度會(hui)產生(sheng)局部擊(ji)穿和放電(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)效率(lv)下(xia)降。

電(dian)除(chu)塵器的(de)基本(ben)原理是利(li)用電(dian)力捕集煙氣中的(de)粉塵，主要包括(kuo)以(yi)下四個相(xiang)互有關的(de)物理過(guo)程(cheng): (1) 氣體的(de)電(dian)離。(2) 粉塵的(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移(yi)動。(4) 荷電(dian)粉塵的(de)捕集。
