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)靜電(dian)(dian)除塵器(qi)是以靜電(dian)(dian)凈化法來(lai)(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉塵，它(ta)的(de)(de)凈化工作(zuo)上要是依(yi)靠電(dian)(dian)暈極(ji)和沉淀兩個系統來(lai)(lai)完成的(de)(de)，當含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時，含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)分布(bu)板以及折流(liu)(liu)(liu)板的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)能較均勻(yun)地進(jin)人(ren)(ren)(ren)電(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)速度迅(xun)速降低，其中(zhong)有些較重(zhong)的(de)(de)塵粒(li)便失去速度而(er)沉降下來(lai)(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)場(chang)的(de)(de)含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈極(ji)通人(ren)(ren)(ren)高壓(ya)直流(liu)(liu)(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈極(ji)附近(jin)產生(sheng)電(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)(li)(li)，電(dian)(dian)離(li)(li)(li)后(hou)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)電(dian)(dian)子(zi)和離(li)(li)(li)子(zi)，這些電(dian)(dian)子(zi)和離(li)(li)(li)子(zi)與(yu)進(jin)人(ren)(ren)(ren)電(dian)(dian)場(chang)的(de)(de)粉塵結合起來(lai)(lai)，使塵粒(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵粒(li)在(zai)電(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下趨向本(ben)設(she)(she)備陽極(ji)(正極(ji)、本(ben)設(she)(she)備采用(yong)負高壓(ya)制)和陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)子(zi)分別(bie)沉積在(zai)相(xiang)應的(de)(de)電(dian)(dian)極(ji)上，通過設(she)(she)備陰陽極(ji)振打系統的(de)(de)振打，使沉積在(zai)陰陽電(dian)(dian)極(ji)上的(de)(de)粉塵振落，進(jin)人(ren)(ren)(ren)集灰斗 通過排(pai)灰裝置放出，回收(shou)有物料(liao)，被)凈化的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排(pai)入大(da)氣(qi)(qi)(qi)(qi)。

工作原(yuan)理

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)工(gong)作(zuo)原理是利用(yong)高壓電(dian)(dian)場(chang)使(shi)煙氣發(fa)生(sheng)電(dian)(dian)離，氣流(liu)中的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作(zuo)用(yong)下與氣流(liu)分離。負極(ji)由(you)不同(tong)(tong)斷面形狀的(de)(de)金屬(shu)導線制成(cheng)，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)(tong)幾何(he)形狀的(de)(de)金屬(shu)板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)性(xing)(xing)能受粉塵(chen)(chen)(chen)性(xing)(xing)質、設備構造(zao)和(he)煙氣流(liu)速等三個因(yin)素(su)的(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)(xing)的(de)(de)指(zhi)標，它對(dui)除塵(chen)(chen)(chen)效(xiao)率有(you)直接的(de)(de)影響。比(bi)電(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)粒難以保(bao)持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上(shang)，致使(shi)其重返氣流(liu)。比(bi)電(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)壓梯度會產(chan)生(sheng)局部擊穿和(he)放(fang)電(dian)(dian)現(xian)象。這些(xie)情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)基本(ben)原理是利用電(dian)(dian)(dian)(dian)力(li)捕集煙(yan)氣(qi)中的(de)(de)粉(fen)塵(chen)(chen)，主要包括以(yi)下四個相互有關的(de)(de)物理過程: (1) 氣(qi)體的(de)(de)電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)(dian)極(ji)移動。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集。
