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)除塵(chen)器是(shi)以(yi)靜(jing)電(dian)凈化(hua)法來(lai)收捕(bu)廢氣(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)，它的(de)(de)(de)凈化(hua)工作上要是(shi)依靠電(dian)暈極(ji)(ji)(ji)(ji)和沉淀兩個(ge)系統(tong)來(lai)完成(cheng)的(de)(de)(de)，當含(han)塵(chen)氣(qi)體進人(ren)(ren)氣(qi)刺叭時(shi)，含(han)塵(chen)氣(qi)體受(shou)到氣(qi)流分(fen)布板以(yi)及折流板的(de)(de)(de)調整后，使(shi)(shi)氣(qi)流能較均勻地進人(ren)(ren)電(dian)場(chang)(chang)(chang)。在(zai)橫(heng)斷面擴大(da)的(de)(de)(de)作用(yong)下(xia)，氣(qi)流速(su)度迅速(su)降低，其中有(you)些較重的(de)(de)(de)塵(chen)粒(li)便失去(qu)速(su)度而(er)沉降下(xia)來(lai)。進人(ren)(ren)電(dian)場(chang)(chang)(chang)的(de)(de)(de)含(han)塵(chen)氣(qi)體由于(yu)電(dian)暈極(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)高壓(ya)直流電(dian)，則在(zai)電(dian)暈極(ji)(ji)(ji)(ji)附近產生電(dian)暈現象，使(shi)(shi)氣(qi)體電(dian)離(li)，電(dian)離(li)后的(de)(de)(de)氣(qi)體中存在(zai)大(da)量的(de)(de)(de)電(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)子(zi)(zi)和離(li)子(zi)(zi)與進人(ren)(ren)電(dian)場(chang)(chang)(chang)的(de)(de)(de)粉(fen)(fen)塵(chen)結合起來(lai)，使(shi)(shi)塵(chen)粒(li)帶電(dian)，帶電(dian)塵(chen)粒(li)在(zai)電(dian)場(chang)(chang)(chang)力(li)的(de)(de)(de)作用(yong)下(xia)趨(qu)向本(ben)設(she)備(bei)(bei)陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)設(she)備(bei)(bei)采(cai)用(yong)負高壓(ya)制)和陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放(fang)(fang)出電(dian)子(zi)(zi)分(fen)別沉積(ji)在(zai)相應的(de)(de)(de)電(dian)極(ji)(ji)(ji)(ji)上，通(tong)過設(she)備(bei)(bei)陰陽(yang)極(ji)(ji)(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)(shi)沉積(ji)在(zai)陰陽(yang)電(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)粉(fen)(fen)塵(chen)振落，進人(ren)(ren)集灰斗 通(tong)過排灰裝置放(fang)(fang)出，回(hui)收有(you)物料，被)凈化(hua)的(de)(de)(de)氣(qi)體排入大(da)氣(qi)。

工作(zuo)原(yuan)理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的工作(zuo)原理是利用(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)作(zuo)用(yong)下與氣(qi)流(liu)分離(li)。負(fu)極(ji)(ji)由不(bu)同斷面形狀的金屬導線制成，叫(jiao)放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何形狀的金屬板制成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的性(xing)能(neng)受粉塵(chen)(chen)(chen)性(xing)質、設備構造和煙氣(qi)流(liu)速(su)等三(san)個因素的影(ying)響。粉塵(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)性(xing)的指(zhi)標，它對除(chu)塵(chen)(chen)(chen)效率(lv)有(you)直接的影(ying)響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過高(gao)，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出，在(zai)(zai)(zai)塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)除塵器(qi)的基本(ben)原理(li)是利用(yong)電(dian)(dian)力捕(bu)集煙氣(qi)中的粉塵，主要包括以下四個相互有關的物理(li)過程(cheng): (1) 氣(qi)體的電(dian)(dian)離(li)。(2) 粉塵的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵的捕(bu)集。
