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)器是以(yi)靜電(dian)(dian)(dian)凈化(hua)(hua)法(fa)來(lai)收(shou)捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)凈化(hua)(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系統(tong)來(lai)完成的(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時(shi)，含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分(fen)布板以(yi)及(ji)折流(liu)(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)場。在(zai)橫斷面擴(kuo)大的(de)(de)(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其(qi)中(zhong)有些(xie)(xie)較重的(de)(de)(de)塵(chen)粒(li)便失去速度而沉降下來(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)暈極(ji)通(tong)(tong)人(ren)(ren)高(gao)壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)附近產(chan)生電(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)子和(he)離子，這些(xie)(xie)電(dian)(dian)(dian)子和(he)離子與進(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)結合起來(lai)，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用(yong)(yong)下趨向(xiang)本設(she)備陽(yang)極(ji)(正(zheng)極(ji)、本設(she)備采用(yong)(yong)負(fu)高(gao)壓制)和(he)陰極(ji)(負(fu)極(ji)) ， 釋放(fang)(fang)出(chu)電(dian)(dian)(dian)子分(fen)別沉積(ji)在(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)極(ji)上(shang)，通(tong)(tong)過設(she)備陰陽(yang)極(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)沉積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)振落，進(jin)人(ren)(ren)集灰(hui)斗 通(tong)(tong)過排灰(hui)裝置放(fang)(fang)出(chu)，回收(shou)有物(wu)料，被)凈化(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)工作原理是(shi)利用(yong)高壓電(dian)(dian)(dian)場使煙(yan)氣(qi)發(fa)生電(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下(xia)與(yu)氣(qi)流(liu)分離。負極(ji)(ji)由(you)不(bu)(bu)同斷面形狀的(de)(de)(de)金屬導線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)(bu)同幾何形狀的(de)(de)(de)金屬板制(zhi)成，叫(jiao)集塵(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)性能受粉(fen)塵(chen)性質、設備(bei)構造和煙(yan)氣(qi)流(liu)速等(deng)三個(ge)因素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)(dian)性的(de)(de)(de)指標，它對除(chu)塵(chen)效(xiao)率有(you)直(zhi)接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻過(guo)低，塵(chen)粒(li)難(nan)以保(bao)持在集塵(chen)電(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)阻過(guo)高，到達(da)集塵(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)荷不(bu)(bu)易放出，在塵(chen)層之間形成電(dian)(dian)(dian)壓梯度(du)會產生局部擊穿和放電(dian)(dian)(dian)現(xian)象(xiang)。這些情況(kuang)都會造成除(chu)塵(chen)效(xiao)率下(xia)降。

電(dian)除塵器的(de)基本原理是(shi)利用電(dian)力捕(bu)集煙(yan)氣中(zhong)的(de)粉塵，主要包括以下四個相互(hu)有關的(de)物理過程: (1) 氣體的(de)電(dian)離。(2) 粉塵的(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移動(dong)。(4) 荷電(dian)粉塵的(de)捕(bu)集。
