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)靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法(fa)來收捕廢(fei)氣中的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈化工作上(shang)要是依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀兩個系(xi)(xi)統來完成的(de)(de)，當含(han)塵(chen)氣體(ti)進(jin)人氣刺叭時(shi)，含(han)塵(chen)氣體(ti)受(shou)到氣流(liu)(liu)分布板以及(ji)折(zhe)流(liu)(liu)板的(de)(de)調整后，使氣流(liu)(liu)能較均勻地(di)進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷(duan)面(mian)擴大(da)的(de)(de)作用下(xia)，氣流(liu)(liu)速(su)度(du)迅速(su)降低，其(qi)中有(you)(you)些較重的(de)(de)塵(chen)粒(li)便(bian)失(shi)去速(su)度(du)而沉(chen)降下(xia)來。進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)氣體(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使氣體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)氣體(ti)中存(cun)在(zai)(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離(li)(li)子(zi)(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離(li)(li)子(zi)(zi)(zi)與進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)結合(he)起來，使塵(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用下(xia)趨向本設(she)備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)采(cai)用負(fu)高壓制)和陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分別(bie)沉(chen)積(ji)在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過(guo)設(she)備(bei)陰陽(yang)極(ji)(ji)振(zhen)打系(xi)(xi)統的(de)(de)振(zhen)打，使沉(chen)積(ji)在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)人集灰斗(dou) 通(tong)過(guo)排灰裝置放(fang)出，回收有(you)(you)物料，被)凈化的(de)(de)氣體(ti)排入大(da)氣。

工作原理(li)

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原(yuan)理是利用高(gao)壓電(dian)(dian)場使(shi)煙(yan)氣(qi)發生(sheng)電(dian)(dian)離，氣(qi)流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)(zai)電(dian)(dian)場作(zuo)用下與(yu)氣(qi)流(liu)分離。負(fu)極(ji)(ji)(ji)由不(bu)同(tong)斷面形(xing)狀的(de)(de)金(jin)屬導(dao)線制(zhi)成，叫放電(dian)(dian)電(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不(bu)同(tong)幾何形(xing)狀的(de)(de)金(jin)屬板制(zhi)成，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)性質、設備(bei)構造和(he)煙(yan)氣(qi)流(liu)速(su)等三個(ge)因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)阻是評價導(dao)電(dian)(dian)性的(de)(de)指標(biao)，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)(chen)效率有直接(jie)的(de)(de)影響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在(zai)(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)上，致使(shi)其重返(fan)氣(qi)流(liu)。比電(dian)(dian)阻過高(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)壓梯度會產生(sheng)局部擊穿和(he)放電(dian)(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)基(ji)本原理是利(li)用電(dian)(dian)力(li)捕集(ji)煙氣中的(de)(de)(de)粉塵(chen)(chen)，主(zhu)要包(bao)括以下四個相互有關(guan)的(de)(de)(de)物理過程: (1) 氣體的(de)(de)(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)(de)(de)荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移(yi)動(dong)。(4) 荷(he)(he)電(dian)(dian)粉塵(chen)(chen)的(de)(de)(de)捕集(ji)。
