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)(dian)(dian)(dian)除塵(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)(de)(de)(de)凈(jing)化(hua)工作(zuo)上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉淀兩個系統來(lai)(lai)完成的(de)(de)(de)(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)體進(jin)(jin)人(ren)(ren)(ren)氣(qi)(qi)刺叭時(shi)，含塵(chen)氣(qi)(qi)體受到氣(qi)(qi)流分布板以及(ji)折(zhe)流板的(de)(de)(de)(de)(de)(de)(de)調(diao)整后，使氣(qi)(qi)流能(neng)較均勻地(di)進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴(kuo)大的(de)(de)(de)(de)(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)流速(su)度(du)迅速(su)降低，其中(zhong)有些較重的(de)(de)(de)(de)(de)(de)(de)塵(chen)粒便失去速(su)度(du)而(er)沉降下(xia)來(lai)(lai)。進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)(de)含塵(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)人(ren)(ren)(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象(xiang)，使氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)體中(zhong)存在(zai)大量的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)(li)子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)(li)子與進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)(de)粉塵(chen)結合起來(lai)(lai)，使塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)(de)作(zuo)用下(xia)趨向本設(she)備陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備采用負(fu)高壓(ya)制)和陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子分別(bie)沉積在(zai)相應的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設(she)備陰陽(yang)(yang)極(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)(de)(de)(de)振(zhen)(zhen)打，使沉積在(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)(de)(de)(de)粉塵(chen)振(zhen)(zhen)落，進(jin)(jin)人(ren)(ren)(ren)集灰斗 通(tong)過排灰裝置放(fang)出(chu)，回收有物料，被)凈(jing)化(hua)的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)體排入大氣(qi)(qi)。

工作(zuo)原(yuan)理

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)工作(zuo)原理(li)是利(li)用高壓電(dian)(dian)場使煙氣(qi)(qi)發(fa)生電(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)在(zai)(zai)電(dian)(dian)場作(zuo)用下(xia)與氣(qi)(qi)流(liu)分離。負極由不同(tong)斷面形(xing)狀的(de)(de)(de)(de)金屬導線(xian)制成(cheng)，叫放(fang)電(dian)(dian)電(dian)(dian)極。正(zheng)極由不同(tong)幾何形(xing)狀的(de)(de)(de)(de)金屬板制成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)性能(neng)受粉塵(chen)(chen)(chen)(chen)(chen)性質(zhi)、設備構造(zao)和煙氣(qi)(qi)流(liu)速等三個因(yin)素的(de)(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比(bi)(bi)電(dian)(dian)阻是評價導電(dian)(dian)性的(de)(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有(you)直接的(de)(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在(zai)(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極上(shang)，致使其重(zhong)返氣(qi)(qi)流(liu)。比(bi)(bi)電(dian)(dian)阻過高，到達(da)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷(he)(he)不易放(fang)出，在(zai)(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)壓梯度會(hui)產生局(ju)部擊穿和放(fang)電(dian)(dian)現象。這些(xie)情況都(dou)會(hui)造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)(chen)效(xiao)率下(xia)降。

電(dian)除塵(chen)(chen)器的(de)基本原理是利用電(dian)力(li)捕(bu)集(ji)煙(yan)氣中的(de)粉塵(chen)(chen)，主要包括(kuo)以下四個(ge)相互有關的(de)物理過程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)(chen)向電(dian)極(ji)移動。(4) 荷電(dian)粉塵(chen)(chen)的(de)捕(bu)集(ji)。
