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)除塵(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)(hua)法來收(shou)捕廢氣(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈(jing)(jing)化(hua)(hua)工(gong)作上要(yao)是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀兩個(ge)系統(tong)來完成的(de)(de)(de)(de)，當含塵(chen)氣(qi)體(ti)進人(ren)氣(qi)刺叭時(shi)，含塵(chen)氣(qi)體(ti)受到(dao)氣(qi)流(liu)(liu)分(fen)布板以(yi)及折流(liu)(liu)板的(de)(de)(de)(de)調整后，使氣(qi)流(liu)(liu)能較均勻地進人(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)作用(yong)下，氣(qi)流(liu)(liu)速(su)度迅速(su)降(jiang)低，其中有些較重的(de)(de)(de)(de)塵(chen)粒便失(shi)去速(su)度而(er)沉降(jiang)下來。進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使氣(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)體(ti)中存在(zai)(zai)大量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)結合起來，使塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用(yong)下趨向本設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用(yong)負高壓制(zhi))和陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉積(ji)在(zai)(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過(guo)設備陰陽極(ji)(ji)(ji)振(zhen)(zhen)打系統(tong)的(de)(de)(de)(de)振(zhen)(zhen)打，使沉積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)(zhen)落，進人(ren)集(ji)灰(hui)斗(dou) 通(tong)過(guo)排(pai)灰(hui)裝置放出，回收(shou)有物(wu)料，被)凈(jing)(jing)化(hua)(hua)的(de)(de)(de)(de)氣(qi)體(ti)排(pai)入大氣(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作(zuo)(zuo)原理是利用高壓(ya)電(dian)(dian)(dian)場使煙氣(qi)(qi)發(fa)生(sheng)電(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)(zuo)用下(xia)與(yu)氣(qi)(qi)流(liu)分離(li)。負極(ji)由不(bu)同斷面形狀的(de)(de)(de)金(jin)屬(shu)導(dao)線制(zhi)成(cheng)(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何(he)形狀的(de)(de)(de)金(jin)屬(shu)板(ban)制(zhi)成(cheng)(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性能(neng)受(shou)粉塵(chen)(chen)(chen)(chen)性質(zhi)、設備構(gou)造(zao)和煙氣(qi)(qi)流(liu)速(su)等三個因素的(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性的(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致(zhi)使其重返氣(qi)(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻過(guo)(guo)高，到達(da)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出(chu)，在塵(chen)(chen)(chen)(chen)層(ceng)之間形成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿(chuan)和放(fang)(fang)電(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)除塵器的基本原理(li)是利用電(dian)力捕集煙(yan)氣(qi)(qi)中的粉(fen)(fen)(fen)塵，主要包(bao)括以下四個相互有(you)關(guan)的物理(li)過程(cheng): (1) 氣(qi)(qi)體的電(dian)離。(2) 粉(fen)(fen)(fen)塵的荷電(dian)。(3) 荷電(dian)粉(fen)(fen)(fen)塵向電(dian)極移動。(4) 荷電(dian)粉(fen)(fen)(fen)塵的捕集。
