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)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)凈化(hua)(hua)法來(lai)收捕廢(fei)氣(qi)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)(hua)工作(zuo)上要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉(chen)淀兩個(ge)系統來(lai)完(wan)成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)體(ti)進人(ren)(ren)氣(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)分(fen)布板以(yi)及折(zhe)流(liu)(liu)板的(de)(de)(de)(de)調整后，使氣(qi)流(liu)(liu)能(neng)較均(jun)勻地進人(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫(heng)斷(duan)面擴(kuo)大(da)的(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)流(liu)(liu)速度迅速降(jiang)低，其中(zhong)有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去(qu)速度而沉(chen)降(jiang)下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人(ren)(ren)高壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使氣(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)體(ti)中(zhong)存(cun)在(zai)(zai)(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這(zhe)些電(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)作(zuo)用(yong)下趨向本(ben)(ben)設(she)備(bei)(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)(ben)設(she)備(bei)(bei)采用(yong)負(fu)高壓制)和陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)(zi)分(fen)別沉(chen)積在(zai)(zai)(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備(bei)(bei)陰陽(yang)極(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)(de)振(zhen)打(da)，使沉(chen)積在(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落(luo)，進人(ren)(ren)集灰斗 通過排灰裝(zhuang)置放(fang)出，回(hui)收有物料，被)凈化(hua)(hua)的(de)(de)(de)(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)工作原(yuan)理(li)是利用高壓電(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流分(fen)離。負(fu)極(ji)由(you)不(bu)同斷面形狀(zhuang)的(de)(de)(de)金屬導(dao)線(xian)制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同幾何形狀(zhuang)的(de)(de)(de)金屬板制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)性能受(shou)粉(fen)塵(chen)(chen)(chen)性質、設備構造和煙(yan)氣(qi)流速等三個因素的(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)(dian)性的(de)(de)(de)指標(biao)，它對除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其(qi)重返(fan)氣(qi)流。比(bi)電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)易(yi)放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)壓梯度會產(chan)生局(ju)部擊穿(chuan)和放(fang)電(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率下(xia)降。

電(dian)(dian)除(chu)塵器的(de)基本原理是利用電(dian)(dian)力捕集(ji)煙(yan)氣(qi)中的(de)粉(fen)塵，主(zhu)要包括(kuo)以(yi)下四個相互有關的(de)物理過(guo)程: (1) 氣(qi)體的(de)電(dian)(dian)離。(2) 粉(fen)塵的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵的(de)捕集(ji)。
