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)(dian)(dian)除塵(chen)(chen)器是以(yi)(yi)靜(jing)電(dian)(dian)(dian)凈(jing)(jing)(jing)化(hua)法來收捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)(jing)(jing)化(hua)工作上要(yao)是依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉(chen)淀(dian)兩(liang)個(ge)系統(tong)來完成的(de)(de)，當含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人氣(qi)(qi)(qi)(qi)(qi)刺(ci)叭時，含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)分(fen)(fen)布板以(yi)(yi)及折流(liu)(liu)板的(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)能(neng)較(jiao)均勻地進(jin)人電(dian)(dian)(dian)場。在橫斷面擴大的(de)(de)作用(yong)(yong)下(xia)，氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)速(su)(su)度(du)(du)迅速(su)(su)降低，其中(zhong)(zhong)有(you)(you)些(xie)較(jiao)重(zhong)的(de)(de)塵(chen)(chen)粒便(bian)失去速(su)(su)度(du)(du)而沉(chen)降下(xia)來。進(jin)人電(dian)(dian)(dian)場的(de)(de)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人高壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)中(zhong)(zhong)存在大量的(de)(de)電(dian)(dian)(dian)子和(he)離子，這(zhe)些(xie)電(dian)(dian)(dian)子和(he)離子與進(jin)人電(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)結合(he)起來，使(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)場力的(de)(de)作用(yong)(yong)下(xia)趨向本(ben)設(she)備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備(bei)采(cai)用(yong)(yong)負高壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分(fen)(fen)別(bie)沉(chen)積在相應(ying)的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設(she)備(bei)陰(yin)陽(yang)極(ji)(ji)振打系統(tong)的(de)(de)振打，使(shi)沉(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)(chen)振落，進(jin)人集灰(hui)斗 通(tong)過排灰(hui)裝置(zhi)放出，回(hui)收有(you)(you)物料(liao)，被)凈(jing)(jing)(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)排入大氣(qi)(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的工(gong)作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)(liu)中的粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)(liu)分離(li)。負(fu)極(ji)(ji)(ji)由(you)不(bu)同斷面(mian)形狀的金屬導線(xian)制(zhi)成(cheng)(cheng)，叫(jiao)(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不(bu)同幾何形狀的金屬板(ban)制(zhi)成(cheng)(cheng)，叫(jiao)(jiao)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的性(xing)能受粉塵(chen)(chen)(chen)性(xing)質(zhi)、設(she)備構(gou)造和煙(yan)氣(qi)流(liu)(liu)速(su)等三個因素的影(ying)響。粉塵(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的指標(biao)，它(ta)對除塵(chen)(chen)(chen)效率有直(zhi)接的影(ying)響。比電(dian)(dian)(dian)(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)(dian)(dian)(dian)極(ji)(ji)(ji)上，致使其(qi)重(zhong)返(fan)氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出(chu)，在塵(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)(cheng)除塵(chen)(chen)(chen)效率下降。

電除塵器的基(ji)本原理是利用電力捕集(ji)煙氣(qi)中的粉(fen)(fen)塵，主要包括以下四個相互有關(guan)的物理過程(cheng): (1) 氣(qi)體(ti)的電離。(2) 粉(fen)(fen)塵的荷(he)電。(3) 荷(he)電粉(fen)(fen)塵向電極(ji)移動(dong)。(4) 荷(he)電粉(fen)(fen)塵的捕集(ji)。
