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)除塵(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)法來收(shou)捕廢氣(qi)(qi)(qi)中的(de)粉(fen)塵(chen)，它的(de)凈化(hua)(hua)工作(zuo)(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩個(ge)系統(tong)來完成的(de)，當含塵(chen)氣(qi)(qi)(qi)體進人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)體受(shou)到(dao)氣(qi)(qi)(qi)流(liu)分布(bu)板以(yi)及折流(liu)板的(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)流(liu)能較(jiao)均勻(yun)地進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷(duan)面擴大(da)的(de)作(zuo)(zuo)用(yong)下，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有些(xie)較(jiao)重(zhong)的(de)塵(chen)粒(li)(li)便失去速(su)度而沉降下來。進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)含塵(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)(qi)(qi)體中存在大(da)量的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)粉(fen)塵(chen)結合起來，使(shi)塵(chen)粒(li)(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)(li)在電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)作(zuo)(zuo)用(yong)下趨(qu)向(xiang)本(ben)設備(bei)陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備(bei)采用(yong)負高壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積(ji)在相應的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，通過設備(bei)陰陽(yang)(yang)極(ji)(ji)振(zhen)打(da)系統(tong)的(de)振(zhen)打(da)，使(shi)沉積(ji)在陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)的(de)粉(fen)塵(chen)振(zhen)落，進人(ren)集灰(hui)斗 通過排(pai)灰(hui)裝置放出(chu)，回收(shou)有物(wu)料，被)凈化(hua)(hua)的(de)氣(qi)(qi)(qi)體排(pai)入(ru)大(da)氣(qi)(qi)(qi)。

工作(zuo)原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除塵器的(de)(de)工作原理是(shi)利(li)用(yong)高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)(qi)流中的(de)(de)粉(fen)塵荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用(yong)下與氣(qi)(qi)(qi)流分離(li)。負(fu)極(ji)(ji)(ji)由不(bu)(bu)同(tong)斷面(mian)形(xing)狀(zhuang)的(de)(de)金(jin)屬(shu)導線制成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不(bu)(bu)同(tong)幾何(he)形(xing)狀(zhuang)的(de)(de)金(jin)屬(shu)板制成，叫集(ji)塵電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵器的(de)(de)性(xing)能受粉(fen)塵性(xing)質、設備構(gou)造(zao)和煙(yan)氣(qi)(qi)(qi)流速等三個因(yin)素的(de)(de)影響。粉(fen)塵的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對(dui)除塵效率有直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵粒(li)難以(yi)保(bao)持在集(ji)塵電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致(zhi)使其重返(fan)氣(qi)(qi)(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達集(ji)塵電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵粒(li)電(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在塵層之間(jian)形(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都會(hui)造(zao)成除塵效率下降。

電除(chu)塵器的(de)(de)(de)(de)基本原理(li)是利用電力捕(bu)集煙氣(qi)中的(de)(de)(de)(de)粉(fen)塵，主要包括以下四個相互有(you)關的(de)(de)(de)(de)物理(li)過程: (1) 氣(qi)體(ti)(ti)的(de)(de)(de)(de)電離。(2) 粉(fen)塵的(de)(de)(de)(de)荷(he)電。(3) 荷(he)電粉(fen)塵向電極移動。(4) 荷(he)電粉(fen)塵的(de)(de)(de)(de)捕(bu)集。
