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(shi)靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈化法來(lai)(lai)收(shou)捕廢氣(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)凈化工作(zuo)上要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和沉淀兩個系(xi)(xi)統來(lai)(lai)完成(cheng)的(de)(de)，當(dang)含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)分(fen)布板(ban)以及折(zhe)流(liu)板(ban)的(de)(de)調(diao)整(zheng)后，使氣(qi)(qi)(qi)流(liu)能較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴(kuo)大的(de)(de)作(zuo)用(yong)(yong)下(xia)，氣(qi)(qi)(qi)流(liu)速度迅(xun)速降低，其中(zhong)(zhong)有(you)(you)些(xie)較(jiao)重(zhong)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒便失去速度而沉降下(xia)來(lai)(lai)。進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通(tong)(tong)人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)(zhong)存在大量的(de)(de)電(dian)(dian)(dian)(dian)子和離(li)子，這些(xie)電(dian)(dian)(dian)(dian)子和離(li)子與進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)(yong)下(xia)趨向(xiang)本設(she)(she)備(bei)(bei)陽(yang)極(ji)(正極(ji)、本設(she)(she)備(bei)(bei)采用(yong)(yong)負高壓(ya)制)和陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分(fen)別(bie)沉積(ji)在相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通(tong)(tong)過(guo)設(she)(she)備(bei)(bei)陰陽(yang)極(ji)振打系(xi)(xi)統的(de)(de)振打，使沉積(ji)在陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)振落，進人(ren)集灰斗 通(tong)(tong)過(guo)排(pai)灰裝置(zhi)放出，回收(shou)有(you)(you)物(wu)料，被)凈化的(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)。

工作原(yuan)理

靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)工作原(yuan)理是利用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)(qi)流分離。負極(ji)由(you)不(bu)(bu)同斷面形狀的(de)(de)(de)(de)金(jin)屬導線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)(bu)同幾(ji)何形狀的(de)(de)(de)(de)金(jin)屬板制(zhi)成，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)性(xing)(xing)能受(shou)粉塵(chen)(chen)性(xing)(xing)質、設備(bei)構造和煙(yan)氣(qi)(qi)流速等三個因(yin)素的(de)(de)(de)(de)影(ying)響。粉塵(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)效(xiao)率(lv)有直接的(de)(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)粒難(nan)以(yi)保持(chi)在(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)高，到(dao)達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)(he)不(bu)(bu)易放出，在(zai)塵(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會產生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況都(dou)會造成除(chu)(chu)塵(chen)(chen)效(xiao)率(lv)下降。

電(dian)(dian)(dian)(dian)除塵(chen)器(qi)的(de)基本(ben)原理是利用(yong)電(dian)(dian)(dian)(dian)力捕(bu)集煙(yan)氣中的(de)粉塵(chen)，主要包括以下四個相互有關的(de)物(wu)理過程: (1) 氣體(ti)(ti)的(de)電(dian)(dian)(dian)(dian)離。(2) 粉塵(chen)的(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉塵(chen)向(xiang)電(dian)(dian)(dian)(dian)極(ji)移(yi)動。(4) 荷電(dian)(dian)(dian)(dian)粉塵(chen)的(de)捕(bu)集。
