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)除(chu)塵器(qi)是(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉塵，它(ta)的(de)(de)(de)凈(jing)(jing)化(hua)(hua)工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和(he)沉(chen)淀(dian)兩個系統來(lai)完成的(de)(de)(de)，當含(han)塵氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)刺(ci)叭時，含(han)塵氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)分布板以(yi)及折(zhe)流(liu)板的(de)(de)(de)調整后(hou)，使氣(qi)(qi)(qi)流(liu)能較(jiao)均勻地(di)進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大的(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)流(liu)速度迅速降低，其中有些較(jiao)重的(de)(de)(de)塵粒便失去速度而沉(chen)降下(xia)來(lai)。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵氣(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附近產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵結合(he)起來(lai)，使塵粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用下(xia)趨(qu)向本設(she)(she)備(bei)陽極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設(she)(she)備(bei)采用負高(gao)壓制)和(he)陰(yin)極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)，通(tong)過(guo)(guo)設(she)(she)備(bei)陰(yin)陽極(ji)(ji)(ji)(ji)(ji)振(zhen)打系統的(de)(de)(de)振(zhen)打，使沉(chen)積在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)粉塵振(zhen)落，進(jin)(jin)人(ren)(ren)集(ji)灰(hui)(hui)斗 通(tong)過(guo)(guo)排(pai)灰(hui)(hui)裝置放出，回收有物料，被)凈(jing)(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入(ru)大氣(qi)(qi)(qi)。

工作原理

靜電(dian)除(chu)塵(chen)(chen)器的(de)(de)工作(zuo)原理是利用高壓(ya)電(dian)場使煙氣發(fa)生電(dian)離(li)，氣流中的(de)(de)粉塵(chen)(chen)荷電(dian)在電(dian)場作(zuo)用下與(yu)氣流分離(li)。負極(ji)由(you)(you)不同(tong)斷(duan)面形(xing)狀的(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)電(dian)電(dian)極(ji)。正極(ji)由(you)(you)不同(tong)幾何形(xing)狀的(de)(de)金(jin)屬板(ban)制成(cheng)，叫集塵(chen)(chen)電(dian)極(ji)。靜電(dian)除(chu)塵(chen)(chen)器的(de)(de)性(xing)(xing)能(neng)受粉塵(chen)(chen)性(xing)(xing)質、設備構造和(he)(he)煙氣流速等三個因素(su)的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比電(dian)阻是評價(jia)導電(dian)性(xing)(xing)的(de)(de)指標，它(ta)對(dui)除(chu)塵(chen)(chen)效率有直接(jie)的(de)(de)影響。比電(dian)阻過低(di)，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)極(ji)上(shang)，致使其重(zhong)返氣流。比電(dian)阻過高，到達集塵(chen)(chen)電(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)荷不易放(fang)出(chu)，在塵(chen)(chen)層之間形(xing)成(cheng)電(dian)壓(ya)梯(ti)度會產生局(ju)部擊穿(chuan)和(he)(he)放(fang)電(dian)現象。這些(xie)情況都會造成(cheng)除(chu)塵(chen)(chen)效率下降。

電(dian)(dian)除塵器(qi)的基本原理是(shi)利用(yong)電(dian)(dian)力捕(bu)(bu)集(ji)煙氣中的粉(fen)塵，主要包括以下四個(ge)相互(hu)有(you)關(guan)的物理過程: (1) 氣體的電(dian)(dian)離。(2) 粉(fen)塵的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵的捕(bu)(bu)集(ji)。
