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(shi)靜(jing)電(dian)(dian)除(chu)塵(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)凈化(hua)法來(lai)(lai)收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工作上(shang)要是(shi)依靠電(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀(dian)兩個系(xi)統來(lai)(lai)完成的(de)(de)(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)體(ti)進人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)分(fen)布板(ban)以及折流(liu)板(ban)的(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流(liu)能較(jiao)均勻地進人(ren)電(dian)(dian)場。在橫斷面擴大的(de)(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)流(liu)速度(du)迅(xun)速降(jiang)低，其(qi)中有些(xie)較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去(qu)速度(du)而沉降(jiang)下(xia)來(lai)(lai)。進人(ren)電(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)高壓直流(liu)電(dian)(dian)，則(ze)在電(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)體(ti)中存在大量的(de)(de)(de)(de)電(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)子(zi)和離(li)子(zi)與(yu)進人(ren)電(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)(lai)，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)場力的(de)(de)(de)(de)作用(yong)下(xia)趨向本(ben)設(she)備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)備(bei)采(cai)用(yong)負高壓制)和陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)子(zi)分(fen)別沉積在相應的(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設(she)備(bei)陰(yin)陽極(ji)(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)振(zhen)打，使(shi)(shi)沉積在陰(yin)陽電(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)振(zhen)落，進人(ren)集灰(hui)斗 通過排灰(hui)裝(zhuang)置放(fang)出，回收(shou)有物料，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工(gong)作(zuo)原(yuan)理是(shi)利用高壓電(dian)(dian)(dian)場使煙氣(qi)發生(sheng)電(dian)(dian)(dian)離(li)(li)，氣(qi)流中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用下與(yu)氣(qi)流分離(li)(li)。負極(ji)(ji)由(you)不(bu)同(tong)(tong)斷(duan)面形(xing)狀的(de)(de)(de)金屬(shu)導線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同(tong)(tong)幾(ji)何形(xing)狀的(de)(de)(de)金屬(shu)板(ban)制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構(gou)造(zao)和煙氣(qi)流速等三個因素(su)的(de)(de)(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻(zu)(zu)是(shi)評價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)(chen)效率(lv)有(you)直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)(chen)粒(li)難(nan)以(yi)保持在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其重返氣(qi)流。比電(dian)(dian)(dian)阻(zu)(zu)過高，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯(ti)度會產生(sheng)局(ju)部擊穿和放電(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵(chen)器的(de)基(ji)本原理是利用(yong)電(dian)力捕(bu)集(ji)煙氣中的(de)粉(fen)塵(chen)，主要包括以(yi)下四個相互有關的(de)物理過程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵(chen)的(de)捕(bu)集(ji)。
