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(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收捕(bu)廢氣中的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈(jing)化工(gong)作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)(chen)淀兩個系統來完(wan)成的(de)(de)，當含塵(chen)(chen)(chen)氣體(ti)進(jin)人(ren)氣刺叭(ba)時，含塵(chen)(chen)(chen)氣體(ti)受到氣流分布板以及(ji)折流板的(de)(de)調整后(hou)，使(shi)(shi)氣流能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴(kuo)大的(de)(de)作用(yong)(yong)(yong)下(xia)，氣流速度迅(xun)速降低，其中有些較重的(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失去速度而(er)沉(chen)(chen)降下(xia)來。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)(chen)氣體(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)高(gao)壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)(shi)氣體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣體(ti)中存(cun)在(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與(yu)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用(yong)(yong)(yong)下(xia)趨向本(ben)設(she)備(bei)陽(yang)極(ji)(正極(ji)、本(ben)設(she)備(bei)采用(yong)(yong)(yong)負(fu)高(gao)壓制)和陰極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)(chen)積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過(guo)設(she)備(bei)陰陽(yang)極(ji)振打系統的(de)(de)振打，使(shi)(shi)沉(chen)(chen)積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)人(ren)集(ji)灰斗 通過(guo)排灰裝(zhuang)置(zhi)放(fang)出，回收有物料，被)凈(jing)化的(de)(de)氣體(ti)排入大氣。

工作原理(li)

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的工作(zuo)原理是(shi)利用(yong)(yong)高壓電(dian)(dian)場使煙氣(qi)發生(sheng)電(dian)(dian)離，氣(qi)流中的粉(fen)(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作(zuo)用(yong)(yong)下與氣(qi)流分(fen)離。負(fu)極(ji)(ji)由不(bu)(bu)同斷面形(xing)狀(zhuang)的金屬導線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)(bu)同幾何形(xing)狀(zhuang)的金屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的性能受(shou)粉(fen)(fen)塵(chen)(chen)(chen)性質、設備(bei)構(gou)造和煙氣(qi)流速等三個因(yin)素(su)的影響。粉(fen)(fen)塵(chen)(chen)(chen)的比電(dian)(dian)阻(zu)(zu)是(shi)評價導電(dian)(dian)性的指標(biao)，它對除(chu)塵(chen)(chen)(chen)效(xiao)率有直(zhi)接的影響。比電(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)粒(li)難以保持在集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流。比電(dian)(dian)阻(zu)(zu)過高，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷(he)不(bu)(bu)易放出，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)壓梯度會產生(sheng)局部擊(ji)穿和放電(dian)(dian)現象。這些情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)效(xiao)率下降。

電(dian)除塵(chen)(chen)(chen)器的(de)(de)基本原理(li)(li)是利用電(dian)力捕(bu)集(ji)(ji)煙氣中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)，主要包括以下四(si)個相互有關的(de)(de)物理(li)(li)過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉(fen)塵(chen)(chen)(chen)的(de)(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉(fen)塵(chen)(chen)(chen)向電(dian)極(ji)移動。(4) 荷(he)(he)電(dian)粉(fen)塵(chen)(chen)(chen)的(de)(de)捕(bu)集(ji)(ji)。
