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)(dian)除(chu)塵(chen)(chen)(chen)器(qi)是以(yi)(yi)靜電(dian)(dian)(dian)凈(jing)化(hua)法來收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈(jing)化(hua)工作上(shang)要是依靠(kao)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和(he)(he)沉(chen)(chen)淀兩個系(xi)統來完成的(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)流分布板以(yi)(yi)及折流板的(de)(de)(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)流能較(jiao)均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)。在橫斷面擴大(da)(da)的(de)(de)(de)(de)(de)(de)作用(yong)(yong)下，氣(qi)(qi)(qi)流速度迅速降低(di)，其中有(you)些(xie)較(jiao)重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)(li)便失去速度而(er)沉(chen)(chen)降下來。進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通人(ren)高壓直流電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在大(da)(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)子和(he)(he)離(li)子，這些(xie)電(dian)(dian)(dian)子和(he)(he)離(li)子與(yu)進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合起來，使塵(chen)(chen)(chen)粒(li)(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)(li)在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)作用(yong)(yong)下趨向本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設(she)備(bei)采用(yong)(yong)負高壓制(zhi))和(he)(he)陰(yin)極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分別沉(chen)(chen)積在相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)，通過設(she)備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)(ji)(ji)振打系(xi)統的(de)(de)(de)(de)(de)(de)振打，使沉(chen)(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振落，進(jin)(jin)人(ren)集灰斗 通過排(pai)灰裝置放出，回(hui)收有(you)物料，被)凈(jing)化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大(da)(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工作原理是利用高壓電(dian)(dian)場使(shi)(shi)煙(yan)氣(qi)(qi)發生電(dian)(dian)離，氣(qi)(qi)流中的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作用下與氣(qi)(qi)流分離。負極(ji)(ji)由不同(tong)斷(duan)面形(xing)狀的(de)(de)金屬導(dao)線制成，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾(ji)何形(xing)狀的(de)(de)金屬板制成，叫集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備(bei)構造和煙(yan)氣(qi)(qi)流速等三個因(yin)素的(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻是評價(jia)導(dao)電(dian)(dian)性的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持在集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使(shi)(shi)其重返氣(qi)(qi)流。比(bi)電(dian)(dian)阻過高，到達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放(fang)出(chu)，在塵(chen)(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)壓梯(ti)度(du)會(hui)產(chan)生局部擊穿和放(fang)電(dian)(dian)現象。這(zhe)些情況都會(hui)造成除(chu)塵(chen)(chen)(chen)效率下降。

電(dian)除塵(chen)(chen)器的基本原理(li)(li)是利用電(dian)力(li)捕集(ji)(ji)煙氣(qi)中的粉塵(chen)(chen)，主要包括以下四個相互有關(guan)的物理(li)(li)過(guo)程(cheng): (1) 氣(qi)體的電(dian)離(li)。(2) 粉塵(chen)(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉塵(chen)(chen)的捕集(ji)(ji)。
