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)(dian)(dian)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢(fei)氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈化(hua)工作上(shang)要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)(chen)淀(dian)兩個系統(tong)來完成的(de)(de)(de)，當(dang)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進人(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時(shi)，含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)(qi)(qi)流分布(bu)板以及(ji)折流板的(de)(de)(de)調(diao)整后，使(shi)(shi)氣(qi)(qi)(qi)(qi)流能(neng)較均(jun)勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫(heng)斷面(mian)擴大(da)的(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流速(su)度迅速(su)降低，其中(zhong)有些較重的(de)(de)(de)塵(chen)(chen)粒便失(shi)去(qu)速(su)度而(er)沉(chen)(chen)降下來。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和離子與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵(chen)(chen)結合(he)起來，使(shi)(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用下趨向(xiang)本(ben)設備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備采用負高壓制(zhi))和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)(chen)積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備陰陽極(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)(shi)沉(chen)(chen)積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)振落，進人(ren)(ren)集灰斗 通過排灰裝置放出(chu)，回(hui)收有物料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的工作(zuo)原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作(zuo)用下與(yu)氣(qi)(qi)流(liu)分離(li)。負極(ji)(ji)(ji)由(you)不同斷面形(xing)狀(zhuang)的金屬導線制成，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不同幾何形(xing)狀(zhuang)的金屬板(ban)制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的性(xing)能(neng)受(shou)粉(fen)塵(chen)(chen)性(xing)質、設(she)備構(gou)造和煙氣(qi)(qi)流(liu)速等三個因素的影響。粉(fen)塵(chen)(chen)的比電(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)性(xing)的指(zhi)標(biao)，它對除塵(chen)(chen)效率有(you)直接的影響。比電(dian)(dian)(dian)(dian)阻過(guo)(guo)低(di)，塵(chen)(chen)粒難以(yi)保持(chi)在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致(zhi)使其重返(fan)氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放(fang)出(chu)，在(zai)塵(chen)(chen)層(ceng)之間形(xing)成電(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局(ju)部擊穿和放(fang)電(dian)(dian)(dian)(dian)現(xian)象。這些情況都會(hui)造成除塵(chen)(chen)效率下降(jiang)。

電除塵(chen)器的(de)基本(ben)原(yuan)理是(shi)利用電力捕集煙氣(qi)中的(de)粉(fen)塵(chen)，主要包括以下四個相互有關的(de)物理過(guo)程: (1) 氣(qi)體的(de)電離。(2) 粉(fen)塵(chen)的(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)向電極移動。(4) 荷(he)電粉(fen)塵(chen)的(de)捕集。
