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)除塵(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)凈化法來收(shou)捕廢氣(qi)(qi)中(zhong)(zhong)(zhong)的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈化工作上要是(shi)依靠電(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和沉(chen)淀(dian)兩個系統來完成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流分(fen)布板以(yi)及折流板的(de)(de)(de)調(diao)整后(hou)，使氣(qi)(qi)流能(neng)較(jiao)均勻地進(jin)人(ren)電(dian)場(chang)。在橫斷面擴大的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)流速(su)度迅速(su)降低，其中(zhong)(zhong)(zhong)有些較(jiao)重(zhong)的(de)(de)(de)塵(chen)(chen)粒(li)便失去(qu)速(su)度而沉(chen)降下(xia)來。進(jin)人(ren)電(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通人(ren)高(gao)壓直流電(dian)，則在電(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附近(jin)產生電(dian)暈(yun)現象(xiang)，使氣(qi)(qi)體(ti)(ti)電(dian)離(li)，電(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)(zhong)(zhong)存在大量的(de)(de)(de)電(dian)子和離(li)子，這些電(dian)子和離(li)子與進(jin)人(ren)電(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)結合(he)起(qi)來，使塵(chen)(chen)粒(li)帶電(dian)，帶電(dian)塵(chen)(chen)粒(li)在電(dian)場(chang)力的(de)(de)(de)作用(yong)下(xia)趨向本設備陽極(ji)(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)(ji)、本設備采用(yong)負(fu)高(gao)壓制(zhi))和陰(yin)極(ji)(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)(ji)) ， 釋放(fang)出(chu)電(dian)子分(fen)別沉(chen)積在相應(ying)的(de)(de)(de)電(dian)極(ji)(ji)(ji)(ji)(ji)上，通過(guo)設備陰(yin)陽極(ji)(ji)(ji)(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)振(zhen)(zhen)打，使沉(chen)積在陰(yin)陽電(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)集(ji)灰(hui)斗 通過(guo)排灰(hui)裝置(zhi)放(fang)出(chu)，回收(shou)有物料(liao)，被)凈化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的工作原理是(shi)利(li)用(yong)高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣發生電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用(yong)下與氣流(liu)分離。負極(ji)由不同斷面形(xing)狀的金屬導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形(xing)狀的金屬板制成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的性能受粉塵(chen)(chen)(chen)性質、設備構(gou)造和煙氣流(liu)速等(deng)三個因素的影響。粉塵(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)阻是(shi)評(ping)價(jia)導電(dian)(dian)(dian)(dian)(dian)性的指標，它(ta)對除塵(chen)(chen)(chen)效率(lv)有直接的影響。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)(chen)粒(li)難以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，致(zhi)使(shi)其重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不易(yi)放出，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會(hui)(hui)產生局部(bu)擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)(hui)造成(cheng)除塵(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)除塵器(qi)的(de)(de)基本原理(li)是利用(yong)電(dian)(dian)力捕集煙氣中(zhong)的(de)(de)粉塵，主要包括以(yi)下四個相互有關的(de)(de)物(wu)理(li)過程: (1) 氣體(ti)(ti)的(de)(de)電(dian)(dian)離。(2) 粉塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵的(de)(de)捕集。
