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)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈化(hua)(hua)法來(lai)(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)凈化(hua)(hua)工作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩個(ge)系統來(lai)(lai)完成(cheng)的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體進人氣(qi)(qi)刺(ci)叭時，含(han)塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)流(liu)能(neng)較均勻地進人電(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫斷面擴(kuo)大(da)(da)的(de)(de)(de)作用下(xia)，氣(qi)(qi)流(liu)速(su)度迅速(su)降低，其中(zhong)有(you)些較重的(de)(de)(de)塵(chen)(chen)粒便失去速(su)度而沉降下(xia)來(lai)(lai)。進人電(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)(tong)人高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)體中(zhong)存(cun)在(zai)(zai)(zai)大(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進人電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下(xia)趨(qu)向本(ben)(ben)設備(bei)陽極(ji)(正極(ji)、本(ben)(ben)設備(bei)采用負高(gao)壓制)和(he)陰(yin)(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分別沉積(ji)在(zai)(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)(tong)過(guo)設備(bei)陰(yin)(yin)陽極(ji)振(zhen)打系統的(de)(de)(de)振(zhen)打，使(shi)沉積(ji)在(zai)(zai)(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振(zhen)落，進人集灰(hui)斗 通(tong)(tong)過(guo)排灰(hui)裝置放出，回收有(you)物料，被)凈化(hua)(hua)的(de)(de)(de)氣(qi)(qi)體排入大(da)(da)氣(qi)(qi)。

工(gong)作原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)工(gong)作(zuo)原(yuan)理是利用高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣發(fa)生電(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣流分離。負極(ji)由不(bu)同(tong)(tong)斷面形狀的(de)(de)(de)金屬(shu)導(dao)線制成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)(tong)幾何形狀的(de)(de)(de)金屬(shu)板制成，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)性能(neng)受粉(fen)(fen)塵(chen)(chen)(chen)性質(zhi)、設備構造(zao)(zao)和煙(yan)氣流速等三個因素(su)的(de)(de)(de)影響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它對(dui)除塵(chen)(chen)(chen)效率有直接的(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以(yi)保(bao)持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到(dao)達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出(chu)，在塵(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿(chuan)和放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些(xie)情況都(dou)會造(zao)(zao)成除塵(chen)(chen)(chen)效率下降(jiang)。

電(dian)除塵(chen)(chen)器的(de)基本原理是利用電(dian)力捕集(ji)煙氣(qi)中的(de)粉塵(chen)(chen)，主要包括以下(xia)四個相互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)(chen)向電(dian)極移動。(4) 荷電(dian)粉塵(chen)(chen)的(de)捕集(ji)。
