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(shi)靜(jing)電除塵(chen)(chen)器(qi)是以靜(jing)電凈(jing)化(hua)法來(lai)收捕(bu)廢(fei)氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)凈(jing)化(hua)工作上(shang)(shang)要是依靠(kao)電暈(yun)(yun)極(ji)(ji)和(he)沉淀兩個系統來(lai)完成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)分(fen)布(bu)板以及(ji)折流(liu)板的(de)(de)調整后(hou)(hou)，使氣(qi)(qi)流(liu)能(neng)較均勻(yun)地進(jin)人(ren)(ren)電場(chang)。在(zai)橫斷面擴大的(de)(de)作用(yong)下(xia)，氣(qi)(qi)流(liu)速(su)度(du)迅速(su)降(jiang)低，其(qi)中有些較重的(de)(de)塵(chen)(chen)粒(li)便(bian)失去速(su)度(du)而沉降(jiang)下(xia)來(lai)。進(jin)人(ren)(ren)電場(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由(you)于電暈(yun)(yun)極(ji)(ji)通(tong)人(ren)(ren)高壓直流(liu)電，則在(zai)電暈(yun)(yun)極(ji)(ji)附(fu)近產生電暈(yun)(yun)現象，使氣(qi)(qi)體(ti)電離(li)，電離(li)后(hou)(hou)的(de)(de)氣(qi)(qi)體(ti)中存在(zai)大量的(de)(de)電子(zi)(zi)和(he)離(li)子(zi)(zi)，這(zhe)些電子(zi)(zi)和(he)離(li)子(zi)(zi)與(yu)進(jin)人(ren)(ren)電場(chang)的(de)(de)粉塵(chen)(chen)結合(he)起來(lai)，使塵(chen)(chen)粒(li)帶電，帶電塵(chen)(chen)粒(li)在(zai)電場(chang)力的(de)(de)作用(yong)下(xia)趨向本設(she)備(bei)(bei)(bei)陽極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)(bei)(bei)采用(yong)負高壓制)和(he)陰(yin)(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放(fang)出(chu)電子(zi)(zi)分(fen)別沉積在(zai)相應的(de)(de)電極(ji)(ji)上(shang)(shang)，通(tong)過設(she)備(bei)(bei)(bei)陰(yin)(yin)陽極(ji)(ji)振(zhen)(zhen)(zhen)打(da)系統的(de)(de)振(zhen)(zhen)(zhen)打(da)，使沉積在(zai)陰(yin)(yin)陽電極(ji)(ji)上(shang)(shang)的(de)(de)粉塵(chen)(chen)振(zhen)(zhen)(zhen)落，進(jin)人(ren)(ren)集灰斗 通(tong)過排灰裝置放(fang)出(chu)，回收有物(wu)料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)工作原理(li)是利用高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用下(xia)與(yu)氣流分(fen)離。負極(ji)(ji)(ji)由不同(tong)斷面形狀的(de)(de)金(jin)(jin)屬(shu)導線制成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同(tong)幾何形狀的(de)(de)金(jin)(jin)屬(shu)板制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設(she)備構(gou)造和煙(yan)氣流速等三個因素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)效率有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致(zhi)使其重返(fan)氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放(fang)(fang)出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部(bu)擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會造成除(chu)塵(chen)(chen)效率下(xia)降(jiang)。

電(dian)(dian)(dian)除塵(chen)(chen)器的(de)基(ji)本原(yuan)理是利用(yong)電(dian)(dian)(dian)力捕(bu)集煙氣中的(de)粉塵(chen)(chen)，主要包括以下四個相互有關的(de)物理過程: (1) 氣體(ti)的(de)電(dian)(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉塵(chen)(chen)的(de)捕(bu)集。
