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(wo)式靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)凈化(hua)法(fa)來(lai)收捕廢氣(qi)(qi)中(zhong)(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈化(hua)工(gong)作上要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)和沉淀(dian)兩個系統來(lai)完(wan)成的(de)(de)(de)，當含(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)刺叭時(shi)，含(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分布板以及折流板的(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)流能(neng)較(jiao)均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)場。在(zai)橫斷面擴大的(de)(de)(de)作用下(xia)，氣(qi)(qi)流速(su)度迅速(su)降低，其中(zhong)(zhong)有些較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便(bian)失去速(su)度而沉降下(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)含(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)暈(yun)(yun)極(ji)通人(ren)高壓直(zhi)流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)體(ti)中(zhong)(zhong)存在(zai)大量(liang)的(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)(zi)和離(li)子(zi)(zi)(zi)，這些電(dian)(dian)(dian)子(zi)(zi)(zi)和離(li)子(zi)(zi)(zi)與(yu)進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合起(qi)來(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場力的(de)(de)(de)作用下(xia)趨(qu)向本設(she)備陽極(ji)(正極(ji)、本設(she)備采(cai)用負高壓制)和陰極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)(zi)(zi)分別沉積在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通過(guo)設(she)備陰陽極(ji)振(zhen)(zhen)打(da)系統的(de)(de)(de)振(zhen)(zhen)打(da)，使(shi)沉積在(zai)陰陽電(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)集灰斗 通過(guo)排灰裝置放出(chu)，回(hui)收有物料(liao)，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)工作原理是利用高壓電(dian)(dian)場(chang)使煙氣發(fa)生電(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)(zai)電(dian)(dian)場(chang)作用下與氣流(liu)分離。負極(ji)(ji)由(you)不(bu)(bu)同斷面形(xing)狀的(de)金屬導線(xian)制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由(you)不(bu)(bu)同幾(ji)何形(xing)狀的(de)金屬板(ban)制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)性能受粉塵(chen)(chen)(chen)性質、設備構造和煙氣流(liu)速等三個因素的(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)阻是評價(jia)導電(dian)(dian)性的(de)指標(biao)，它對(dui)除塵(chen)(chen)(chen)效率有直接的(de)影(ying)響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持(chi)在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其重返氣流(liu)。比電(dian)(dian)阻過高，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)(bu)易放(fang)出，在(zai)(zai)塵(chen)(chen)(chen)層之(zhi)間形(xing)成(cheng)電(dian)(dian)壓梯度會產生局部擊(ji)穿和放(fang)電(dian)(dian)現象。這些情況都會造成(cheng)除塵(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵器的(de)基本(ben)原理是利用電(dian)(dian)(dian)力捕集煙氣中的(de)粉(fen)塵，主要包括(kuo)以下四個相互有關的(de)物理過程(cheng): (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)塵的(de)捕集。
