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(wo)式(shi)靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢氣(qi)(qi)中(zhong)(zhong)的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈化工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)淀(dian)兩(liang)個系統(tong)來完(wan)成(cheng)的(de)(de)(de)，當含(han)(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)(ti)進人氣(qi)(qi)刺叭時(shi)，含(han)(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分布板以(yi)及折流(liu)(liu)板的(de)(de)(de)調整后，使氣(qi)(qi)流(liu)(liu)能較(jiao)(jiao)均勻(yun)地進人電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷(duan)面擴大(da)(da)的(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)(liu)速(su)(su)度迅速(su)(su)降低(di)，其中(zhong)(zhong)有(you)些(xie)較(jiao)(jiao)重的(de)(de)(de)塵(chen)(chen)粒(li)(li)便失(shi)去速(su)(su)度而沉(chen)降下來。進人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人高(gao)壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)(ti)中(zhong)(zhong)存(cun)在(zai)(zai)大(da)(da)量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)(li)子，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)(li)子與(yu)進人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)結合起來，使塵(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用(yong)下趨向(xiang)本(ben)設備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備采用(yong)負高(gao)壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過設備陰(yin)陽極(ji)(ji)振打(da)系統(tong)的(de)(de)(de)振打(da)，使沉(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)振落，進人集灰(hui)斗(dou) 通(tong)過排灰(hui)裝置放(fang)出，回收(shou)有(you)物料，被)凈化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)(ti)排入大(da)(da)氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的工作原(yuan)理是利(li)用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中(zhong)的粉(fen)(fen)(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)流分離。負(fu)極(ji)由不同斷面形狀(zhuang)的金屬導線制(zhi)成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何(he)形狀(zhuang)的金屬板(ban)制(zhi)成，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的性(xing)能受粉(fen)(fen)(fen)塵(chen)(chen)性(xing)質、設備構造和煙氣(qi)流速等三(san)個因素的影響。粉(fen)(fen)(fen)塵(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)(dian)性(xing)的指標，它對除塵(chen)(chen)效率有(you)直接(jie)的影響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重(zhong)返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻過高，到(dao)達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在(zai)塵(chen)(chen)層(ceng)之(zhi)間形成電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生(sheng)局部(bu)擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都(dou)會造成除塵(chen)(chen)效率下降。

電(dian)(dian)除塵器的(de)(de)基本原理是利(li)用電(dian)(dian)力(li)捕集煙(yan)氣(qi)(qi)中(zhong)的(de)(de)粉(fen)塵，主(zhu)要包括以下四個(ge)相互有關(guan)的(de)(de)物理過(guo)程(cheng): (1) 氣(qi)(qi)體(ti)的(de)(de)電(dian)(dian)離。(2) 粉(fen)塵的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵向(xiang)電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵的(de)(de)捕集。
