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(chu)塵(chen)(chen)器是以靜(jing)電(dian)凈(jing)化(hua)法來收捕廢氣(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)工作(zuo)上要(yao)是依(yi)靠電(dian)暈(yun)極(ji)(ji)(ji)和沉(chen)淀兩個系(xi)統來完(wan)成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)人氣(qi)刺(ci)叭(ba)時，含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)(liu)分布板(ban)以及折(zhe)流(liu)(liu)板(ban)的(de)(de)(de)(de)調整(zheng)后，使氣(qi)流(liu)(liu)能較(jiao)均勻地進(jin)人電(dian)場。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)作(zuo)用下，氣(qi)流(liu)(liu)速(su)(su)度迅速(su)(su)降低，其中有(you)些較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒(li)(li)便失去速(su)(su)度而沉(chen)降下來。進(jin)人電(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)暈(yun)極(ji)(ji)(ji)通人高壓(ya)直(zhi)流(liu)(liu)電(dian)，則在(zai)電(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)暈(yun)現象，使氣(qi)體(ti)(ti)(ti)電(dian)離，電(dian)離后的(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)中存在(zai)大(da)量的(de)(de)(de)(de)電(dian)子和離子，這些電(dian)子和離子與進(jin)人電(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)結合起(qi)來，使塵(chen)(chen)粒(li)(li)帶電(dian)，帶電(dian)塵(chen)(chen)粒(li)(li)在(zai)電(dian)場力的(de)(de)(de)(de)作(zuo)用下趨(qu)向(xiang)本(ben)設備(bei)(bei)陽極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本(ben)設備(bei)(bei)采用負高壓(ya)制)和陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)子分別沉(chen)積在(zai)相應(ying)的(de)(de)(de)(de)電(dian)極(ji)(ji)(ji)上，通過設備(bei)(bei)陰(yin)陽極(ji)(ji)(ji)振打(da)系(xi)統的(de)(de)(de)(de)振打(da)，使沉(chen)積在(zai)陰(yin)陽電(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)振落，進(jin)人集(ji)灰(hui)斗 通過排灰(hui)裝置放出，回收有(you)物料，被)凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)排入大(da)氣(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)(de)工作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣流(liu)(liu)分離。負極(ji)由(you)不同(tong)斷面形狀的(de)(de)(de)(de)(de)金屬導(dao)線制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何形狀的(de)(de)(de)(de)(de)金屬板制成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)(de)性(xing)能受(shou)粉塵(chen)(chen)(chen)性(xing)質、設備構造和煙氣流(liu)(liu)速(su)等(deng)三個因素(su)的(de)(de)(de)(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)效率有(you)直(zhi)接(jie)的(de)(de)(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重(zhong)返氣流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到(dao)達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出(chu)，在塵(chen)(chen)(chen)層之間(jian)形成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都會(hui)造成除塵(chen)(chen)(chen)效率下降。

電除塵(chen)器的(de)(de)基本原理是(shi)利用(yong)電力捕(bu)集(ji)煙氣中的(de)(de)粉塵(chen)，主(zhu)要(yao)包括以下四個相互(hu)有關的(de)(de)物理過程: (1) 氣體的(de)(de)電離。(2) 粉塵(chen)的(de)(de)荷(he)電。(3) 荷(he)電粉塵(chen)向電極移(yi)動。(4) 荷(he)電粉塵(chen)的(de)(de)捕(bu)集(ji)。
