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)(dian)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕(bu)廢(fei)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈化工(gong)作上(shang)(shang)要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉(chen)(chen)(chen)淀兩個系(xi)統來(lai)完成的(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體進人(ren)氣(qi)(qi)(qi)(qi)刺叭時(shi)，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)(qi)流能較均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大的(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)流速度迅速降低，其(qi)中(zhong)(zhong)有些(xie)較重的(de)(de)(de)塵(chen)(chen)粒便(bian)失去速度而(er)沉(chen)(chen)(chen)降下來(lai)。進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)(tong)人(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體中(zhong)(zhong)存在(zai)大量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離(li)(li)子(zi)(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離(li)(li)子(zi)(zi)(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合起(qi)來(lai)，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下趨向(xiang)本(ben)設(she)備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備(bei)采用(yong)負(fu)高壓制(zhi))和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分(fen)別沉(chen)(chen)(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，通(tong)(tong)過設(she)備(bei)陰陽(yang)極(ji)(ji)振打(da)系(xi)統的(de)(de)(de)振打(da)，使(shi)沉(chen)(chen)(chen)積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進人(ren)集灰(hui)(hui)斗(dou) 通(tong)(tong)過排灰(hui)(hui)裝(zhuang)置放出，回收有物料，被)凈化的(de)(de)(de)氣(qi)(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)工作(zuo)(zuo)原理是(shi)利(li)用(yong)高壓電(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流中(zhong)的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作(zuo)(zuo)用(yong)下與氣(qi)(qi)流分離。負(fu)極(ji)由(you)不(bu)同(tong)斷(duan)面形狀(zhuang)的(de)(de)金屬導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同(tong)幾(ji)何(he)形狀(zhuang)的(de)(de)金屬板制成，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)性能受粉塵(chen)(chen)性質(zhi)、設(she)備構造(zao)和(he)煙氣(qi)(qi)流速等三(san)個因素的(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻(zu)(zu)是(shi)評(ping)價(jia)導電(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)效率有直接(jie)的(de)(de)影響(xiang)。比電(dian)(dian)(dian)阻(zu)(zu)過(guo)低(di)，塵(chen)(chen)粒(li)難以保持(chi)在(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致(zhi)使(shi)其(qi)重(zhong)返氣(qi)(qi)流。比電(dian)(dian)(dian)阻(zu)(zu)過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)易放出，在(zai)(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯度會(hui)產(chan)生局部擊(ji)穿和(he)放電(dian)(dian)(dian)現(xian)象。這些情況都會(hui)造(zao)成除(chu)塵(chen)(chen)效率下降(jiang)。

電(dian)除(chu)塵(chen)(chen)器的基本原理(li)是利用電(dian)力捕集煙(yan)氣中的粉塵(chen)(chen)，主(zhu)要包括以下四(si)個相互有(you)關的物(wu)理(li)過程: (1) 氣體的電(dian)離。(2) 粉塵(chen)(chen)的荷電(dian)。(3) 荷電(dian)粉塵(chen)(chen)向電(dian)極移動。(4) 荷電(dian)粉塵(chen)(chen)的捕集。
