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)除塵(chen)(chen)(chen)器(qi)是以(yi)靜電(dian)(dian)(dian)凈化法(fa)來收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)凈化工(gong)作(zuo)上要是依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)(chen)(chen)淀兩(liang)個系統來完成的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分布板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)(de)調整后，使氣(qi)(qi)流(liu)(liu)能較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷(duan)面擴大(da)的(de)(de)(de)作(zuo)用下，氣(qi)(qi)流(liu)(liu)速度迅(xun)速降(jiang)低，其(qi)中(zhong)有些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)粒便失去速度而(er)沉(chen)(chen)(chen)降(jiang)下來。進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)子和離子與進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用下趨向本設(she)備陽極(ji)(ji)(正極(ji)(ji)、本設(she)備采用負高壓(ya)制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分別沉(chen)(chen)(chen)積(ji)在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備陰(yin)陽極(ji)(ji)振(zhen)打系統的(de)(de)(de)振(zhen)打，使沉(chen)(chen)(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落(luo)，進(jin)人(ren)(ren)集灰(hui)斗 通過排(pai)灰(hui)裝(zhuang)置放(fang)出，回收有物料，被(bei))凈化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)排(pai)入大(da)氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)工作(zuo)原(yuan)理是(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)(qi)流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)(qi)(qi)流(liu)分(fen)離。負極(ji)(ji)(ji)由不同斷(duan)面形狀的(de)金屬(shu)導線(xian)制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同幾(ji)何(he)形狀的(de)金屬(shu)板制成(cheng)，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)性能受粉(fen)塵(chen)(chen)性質、設備構造和煙氣(qi)(qi)(qi)流(liu)速等(deng)三個因(yin)素的(de)影響。粉(fen)塵(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)效(xiao)率有直接(jie)的(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致(zhi)使(shi)其重返氣(qi)(qi)(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不易(yi)放(fang)出(chu)，在(zai)塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造成(cheng)除塵(chen)(chen)效(xiao)率下降。

電(dian)除塵器的(de)基本原理(li)是利用(yong)電(dian)力捕集(ji)煙氣(qi)中的(de)粉(fen)塵，主要(yao)包括以下四個相互有關的(de)物(wu)理(li)過程: (1) 氣(qi)體的(de)電(dian)離(li)。(2) 粉(fen)塵的(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向電(dian)極移動。(4) 荷電(dian)粉(fen)塵的(de)捕集(ji)。
