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。

臥式靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)是以(yi)靜電(dian)(dian)(dian)凈(jing)化(hua)法來收捕廢(fei)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)工作(zuo)上要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉淀兩個系統(tong)來完成(cheng)的(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)(qi)流(liu)(liu)能較均勻地進(jin)人(ren)電(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)(qi)(qi)流(liu)(liu)速度迅(xun)速降(jiang)低，其中(zhong)(zhong)有(you)些(xie)較重(zhong)的(de)(de)塵(chen)(chen)粒(li)(li)便失去速度而(er)沉降(jiang)下來。進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在(zai)大(da)量(liang)的(de)(de)電(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)子和離子與進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)結合起(qi)來，使塵(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒(li)(li)在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用(yong)(yong)下趨向本(ben)設備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備采(cai)用(yong)(yong)負(fu)高壓制)和陰(yin)(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分別(bie)沉積(ji)在(zai)相(xiang)應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設備陰(yin)(yin)陽極(ji)(ji)振(zhen)打系統(tong)的(de)(de)振(zhen)打，使沉積(ji)在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)(chen)振(zhen)落(luo)，進(jin)人(ren)集(ji)灰(hui)斗 通(tong)過排灰(hui)裝置放出，回收有(you)物料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原理是利用(yong)高(gao)壓電(dian)(dian)(dian)場(chang)使煙氣發生電(dian)(dian)(dian)離，氣流(liu)中的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作(zuo)用(yong)下與氣流(liu)分離。負極由不同(tong)斷面形(xing)狀的(de)(de)金屬導線制成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不同(tong)幾何形(xing)狀的(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣流(liu)速等三(san)個因素(su)的(de)(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)性(xing)的(de)(de)指標，它(ta)對(dui)除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)粒難(nan)以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其重返(fan)氣流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過(guo)高(gao)，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放出(chu)，在(zai)塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產(chan)生局部擊穿和放電(dian)(dian)(dian)現象。這(zhe)些情況都會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的基(ji)本(ben)原(yuan)理(li)是利用電(dian)(dian)(dian)(dian)力捕集煙氣中的粉塵(chen)(chen)，主要包括以下四個相互有關的物理(li)過程: (1) 氣體的電(dian)(dian)(dian)(dian)離。(2) 粉塵(chen)(chen)的荷(he)電(dian)(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)(chen)的捕集。
