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(wo)式靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收捕(bu)廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉塵，它的(de)(de)凈(jing)化工作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)(he)沉(chen)(chen)淀(dian)兩個系統(tong)來完成(cheng)的(de)(de)，當(dang)含(han)塵氣(qi)(qi)(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭(ba)時，含(han)塵氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板以及折(zhe)流(liu)(liu)板的(de)(de)調(diao)整(zheng)后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)能較(jiao)均勻(yun)地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面(mian)擴大(da)(da)的(de)(de)作用下(xia)(xia)(xia)，氣(qi)(qi)(qi)(qi)流(liu)(liu)速度(du)迅(xun)速降低，其中(zhong)有些較(jiao)重的(de)(de)塵粒(li)便失去(qu)速度(du)而沉(chen)(chen)降下(xia)(xia)(xia)來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)含(han)塵氣(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中(zhong)存在大(da)(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉塵結合(he)起(qi)來，使塵粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用下(xia)(xia)(xia)趨向本設(she)備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備采用負(fu)高壓制)和(he)(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)(chen)積(ji)在相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設(she)備陰(yin)陽極(ji)(ji)(ji)振打系統(tong)的(de)(de)振打，使沉(chen)(chen)積(ji)在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)粉塵振落，進(jin)人(ren)(ren)集灰斗 通過排(pai)灰裝置放出(chu)，回(hui)收有物料，被)凈(jing)化的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排(pai)入大(da)(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜(jing)(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作原理是(shi)利用(yong)高(gao)壓電(dian)(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)(dian)離，氣流中的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下(xia)(xia)與氣流分離。負極(ji)由不同(tong)斷面(mian)形狀的(de)(de)金(jin)屬導(dao)線制成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形狀的(de)(de)金(jin)屬板制成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能(neng)受粉(fen)塵(chen)(chen)性質、設備構造和煙氣流速等三個因(yin)素的(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)(dian)性的(de)(de)指標(biao)，它對(dui)除(chu)塵(chen)(chen)效率有(you)直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使其重返氣流。比(bi)電(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)層(ceng)之(zhi)間形成(cheng)(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情(qing)況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)效率下(xia)(xia)降。

電除(chu)塵器的(de)基本原理(li)是利用電力捕(bu)集(ji)煙(yan)氣中的(de)粉塵，主要包括(kuo)以下四個相(xiang)互有(you)關的(de)物理(li)過程: (1) 氣體(ti)(ti)的(de)電離。(2) 粉塵的(de)荷(he)電。(3) 荷(he)電粉塵向(xiang)電極移動。(4) 荷(he)電粉塵的(de)捕(bu)集(ji)。
