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(shi)靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)是(shi)以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)化法來收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化工作上要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)淀兩個系統來完成的(de)(de)(de)(de)，當含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體進(jin)人氣(qi)(qi)(qi)(qi)刺叭時，含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)(liu)分布板以(yi)及折流(liu)(liu)(liu)(liu)板的(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)(liu)能較(jiao)均勻地(di)進(jin)人電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大的(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)(liu)速度迅速降(jiang)低，其(qi)中(zhong)有(you)些(xie)(xie)較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失(shi)去(qu)速度而(er)沉(chen)降(jiang)下來。進(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)通人高壓直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體中(zhong)存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)，這(zhe)些(xie)(xie)電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)與進(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起(qi)來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用(yong)下趨向本(ben)設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備采用(yong)負高壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通過(guo)設備陰陽(yang)極(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)振(zhen)(zhen)打，使沉(chen)積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振(zhen)(zhen)落，進(jin)人集灰斗 通過(guo)排灰裝(zhuang)置(zhi)放出，回(hui)收有(you)物料，被(bei))凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)(qi)。

工(gong)作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)(de)(de)(de)工作(zuo)原理是利用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流中的(de)(de)(de)(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流分離(li)。負極由不同斷面形(xing)狀(zhuang)的(de)(de)(de)(de)(de)金屬導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不同幾何形(xing)狀(zhuang)的(de)(de)(de)(de)(de)金屬板制成(cheng)，叫(jiao)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設(she)備構造(zao)和煙(yan)氣(qi)流速等三個因(yin)素的(de)(de)(de)(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)的(de)(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)(de)指標，它(ta)對除(chu)(chu)塵(chen)效(xiao)率有直(zhi)接的(de)(de)(de)(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)粒(li)難以(yi)保持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其(qi)重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況(kuang)都(dou)會(hui)造(zao)成(cheng)除(chu)(chu)塵(chen)效(xiao)率下降(jiang)。

電(dian)除(chu)塵器的(de)基本原理是利(li)用電(dian)力(li)捕集煙氣(qi)中的(de)粉(fen)塵，主要包括以下四個相互(hu)有關(guan)的(de)物理過程: (1) 氣(qi)體(ti)的(de)電(dian)離。(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。
