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)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)法來收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)(hua)工作(zuo)上(shang)(shang)要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉淀(dian)兩個系(xi)統(tong)來完成(cheng)的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)流(liu)分布(bu)板(ban)以及折流(liu)板(ban)的(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)流(liu)能較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴(kuo)大(da)的(de)(de)(de)作(zuo)用下(xia)(xia)，氣(qi)(qi)(qi)流(liu)速度(du)迅速降低，其中有些(xie)較重的(de)(de)(de)塵(chen)(chen)粒(li)便(bian)失(shi)去速度(du)而沉降下(xia)(xia)來。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附(fu)近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用下(xia)(xia)趨向(xiang)本設(she)(she)備(bei)陽極(ji)(正(zheng)極(ji)、本設(she)(she)備(bei)采用負高(gao)壓(ya)制(zhi))和陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通過設(she)(she)備(bei)陰(yin)陽極(ji)振(zhen)打系(xi)統(tong)的(de)(de)(de)振(zhen)打，使(shi)(shi)沉積在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振(zhen)落，進人(ren)(ren)集灰斗 通過排灰裝置放出，回(hui)收有物料，被)凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)除(chu)(chu)(chu)塵(chen)器的(de)(de)工(gong)作(zuo)原理是(shi)利用高(gao)(gao)壓電(dian)場使煙氣(qi)(qi)發(fa)生(sheng)電(dian)離(li)，氣(qi)(qi)流(liu)(liu)中的(de)(de)粉(fen)塵(chen)荷電(dian)在電(dian)場作(zuo)用下(xia)(xia)與氣(qi)(qi)流(liu)(liu)分離(li)。負(fu)極(ji)(ji)(ji)(ji)由(you)不同斷面形狀(zhuang)的(de)(de)金屬導線制(zhi)成，叫放(fang)(fang)電(dian)電(dian)極(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)由(you)不同幾何形狀(zhuang)的(de)(de)金屬板制(zhi)成，叫集(ji)塵(chen)電(dian)極(ji)(ji)(ji)(ji)。靜電(dian)除(chu)(chu)(chu)塵(chen)器的(de)(de)性能受粉(fen)塵(chen)性質、設備構造和煙氣(qi)(qi)流(liu)(liu)速等三個(ge)因素的(de)(de)影響。粉(fen)塵(chen)的(de)(de)比電(dian)阻(zu)是(shi)評價導電(dian)性的(de)(de)指標，它對(dui)除(chu)(chu)(chu)塵(chen)效(xiao)率有(you)直(zhi)接的(de)(de)影響。比電(dian)阻(zu)過低(di)，塵(chen)粒(li)難以保持(chi)在集(ji)塵(chen)電(dian)極(ji)(ji)(ji)(ji)上，致使其重返(fan)氣(qi)(qi)流(liu)(liu)。比電(dian)阻(zu)過高(gao)(gao)，到達集(ji)塵(chen)電(dian)極(ji)(ji)(ji)(ji)的(de)(de)塵(chen)粒(li)電(dian)荷不易放(fang)(fang)出，在塵(chen)層之間(jian)形成電(dian)壓梯度會(hui)產(chan)生(sheng)局部擊穿(chuan)和放(fang)(fang)電(dian)現象。這些情況都(dou)會(hui)造成除(chu)(chu)(chu)塵(chen)效(xiao)率下(xia)(xia)降(jiang)。

電(dian)除(chu)塵器的(de)基本原理是利用電(dian)力捕集煙(yan)氣中的(de)粉塵，主要包(bao)括(kuo)以下四(si)個(ge)相(xiang)互有關(guan)的(de)物理過程: (1) 氣體的(de)電(dian)離。(2) 粉塵的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵向電(dian)極移動。(4) 荷(he)電(dian)粉塵的(de)捕集。
