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(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)(yi)靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化法來收捕廢氣(qi)(qi)中(zhong)(zhong)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)化工作(zuo)上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和沉(chen)淀兩個系(xi)統(tong)來完成的(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)流(liu)(liu)(liu)分布板(ban)以(yi)(yi)及折流(liu)(liu)(liu)板(ban)的(de)(de)(de)(de)(de)調(diao)整后(hou)，使氣(qi)(qi)流(liu)(liu)(liu)能(neng)較均(jun)勻地(di)進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場。在橫(heng)斷面(mian)擴大的(de)(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)(liu)(liu)速度(du)迅速降低，其中(zhong)(zhong)有(you)些(xie)較重(zhong)的(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速度(du)而沉(chen)降下來。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)(ren)高壓(ya)(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子和離(li)子，這些(xie)電(dian)(dian)(dian)(dian)子和離(li)子與進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合起來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作(zuo)用(yong)下趨(qu)向(xiang)本(ben)設(she)(she)備(bei)陽(yang)極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本(ben)設(she)(she)備(bei)采用(yong)負高壓(ya)(ya)制)和陰(yin)極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)，通(tong)過設(she)(she)備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)(ji)(ji)振打(da)(da)系(xi)統(tong)的(de)(de)(de)(de)(de)振打(da)(da)，使沉(chen)積(ji)在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落，進人(ren)(ren)(ren)集灰斗 通(tong)過排(pai)灰裝置(zhi)放出(chu)，回收有(you)物料，被)凈(jing)化的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)工(gong)作(zuo)原理是(shi)(shi)利用高壓電(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣發生(sheng)電(dian)(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作(zuo)用下與氣流(liu)分(fen)離。負極(ji)由不同(tong)斷面形(xing)狀的(de)金屬(shu)導線制成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形(xing)狀的(de)金屬(shu)板制成(cheng)，叫集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)性能受粉塵(chen)(chen)(chen)(chen)性質、設備構造和煙(yan)氣流(liu)速等(deng)三個因素的(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)阻是(shi)(shi)評價(jia)導電(dian)(dian)(dian)性的(de)指標(biao)，它對除(chu)塵(chen)(chen)(chen)(chen)效率有直(zhi)接的(de)影(ying)響。比電(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)(chen)粒難以保持(chi)在集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣流(liu)。比電(dian)(dian)(dian)阻過(guo)高，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層之(zhi)間(jian)形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會(hui)產(chan)生(sheng)局部擊穿(chuan)和放(fang)電(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)除塵(chen)器的(de)(de)基本原理(li)是利用(yong)電(dian)力捕集煙氣中的(de)(de)粉(fen)(fen)塵(chen)，主要包括以下四個相互有關的(de)(de)物(wu)理(li)過(guo)程: (1) 氣體的(de)(de)電(dian)離(li)。(2) 粉(fen)(fen)塵(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)向(xiang)電(dian)極移動。(4) 荷電(dian)粉(fen)(fen)塵(chen)的(de)(de)捕集。
