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)除塵(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈化法(fa)來(lai)收捕(bu)廢氣(qi)(qi)(qi)(qi)(qi)中的粉塵(chen)(chen)，它的凈化工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩個(ge)系統(tong)來(lai)完(wan)成的，當含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)分(fen)布板以及(ji)折流(liu)板的調(diao)整后(hou)，使氣(qi)(qi)(qi)(qi)(qi)流(liu)能較均(jun)勻地進人電(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷面擴大的作(zuo)用(yong)下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速度迅(xun)速降低，其中有些較重的塵(chen)(chen)粒(li)便失去速度而(er)沉降下來(lai)。進人電(dian)(dian)(dian)(dian)場(chang)的含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后(hou)的氣(qi)(qi)(qi)(qi)(qi)體(ti)中存在(zai)(zai)(zai)大量的電(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)與進人電(dian)(dian)(dian)(dian)場(chang)的粉塵(chen)(chen)結合起來(lai)，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)力的作(zuo)用(yong)下趨(qu)向本設備陽極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)負(fu)高(gao)壓制)和陰(yin)(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子(zi)分(fen)別(bie)沉積(ji)在(zai)(zai)(zai)相(xiang)應的電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過(guo)設備陰(yin)(yin)陽極(ji)(ji)振打(da)系統(tong)的振打(da)，使沉積(ji)在(zai)(zai)(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的粉塵(chen)(chen)振落，進人集(ji)灰(hui)斗 通(tong)過(guo)排(pai)灰(hui)裝置放出，回收有物(wu)料，被)凈化的氣(qi)(qi)(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)(qi)(qi)。

工作原(yuan)理(li)

靜(jing)電(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)工作原理是利用高(gao)(gao)壓電(dian)場(chang)使(shi)煙氣發生電(dian)離，氣流中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)在(zai)電(dian)場(chang)作用下與氣流分離。負極(ji)(ji)由不(bu)同(tong)斷面形狀(zhuang)的(de)(de)(de)(de)金屬導線(xian)制成(cheng)，叫放電(dian)電(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同(tong)幾何形狀(zhuang)的(de)(de)(de)(de)金屬板制成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)。靜(jing)電(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構(gou)造和(he)煙氣流速等三個因(yin)素的(de)(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)阻(zu)是評價導電(dian)性(xing)的(de)(de)(de)(de)指標，它(ta)對除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)(de)影(ying)響。比電(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)粒難(nan)以保(bao)持在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)上，致(zhi)使(shi)其重返氣流。比電(dian)阻(zu)過高(gao)(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)壓梯(ti)度會(hui)(hui)產生局(ju)部擊穿和(he)放電(dian)現象。這些(xie)情(qing)況都會(hui)(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)器的(de)基本原理是利(li)用電(dian)(dian)(dian)力(li)捕集煙(yan)氣(qi)中的(de)粉(fen)塵(chen)，主要包括以下四(si)個相互(hu)有關(guan)的(de)物理過(guo)程: (1) 氣(qi)體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)極(ji)移動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)的(de)捕集。
