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)(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)凈化(hua)法(fa)來收捕(bu)廢氣(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈化(hua)工作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉淀兩個系統來完成的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)受(shou)到氣(qi)(qi)流分布板(ban)(ban)以及折流板(ban)(ban)的(de)(de)調整后，使氣(qi)(qi)流能較(jiao)均勻(yun)地進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)作用(yong)(yong)下(xia)，氣(qi)(qi)流速度迅速降(jiang)低，其中(zhong)有(you)(you)些較(jiao)重的(de)(de)塵(chen)(chen)(chen)粒便失去速度而沉降(jiang)下(xia)來。進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)(tong)人(ren)(ren)高(gao)(gao)壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)與進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)(chen)結合起(qi)來，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)(yong)下(xia)趨向本設備(bei)(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)(bei)采(cai)用(yong)(yong)負高(gao)(gao)壓制(zhi))和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)(tong)過設備(bei)(bei)陰陽(yang)極(ji)(ji)振打系統的(de)(de)振打，使沉積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)(jin)(jin)人(ren)(ren)集灰斗(dou) 通(tong)(tong)過排灰裝(zhuang)置放出，回收有(you)(you)物料(liao)，被)凈化(hua)的(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)(de)工作原理是利用(yong)高(gao)壓電(dian)(dian)(dian)(dian)場(chang)(chang)使煙氣發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣流中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)作用(yong)下與氣流分離(li)。負極由(you)不同斷面(mian)形(xing)狀的(de)(de)(de)金屬(shu)導(dao)線(xian)制(zhi)成，叫放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由(you)不同幾何形(xing)狀的(de)(de)(de)金屬(shu)板制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受(shou)粉塵(chen)(chen)(chen)性(xing)質、設備構(gou)造和煙氣流速等三個因素(su)的(de)(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻是評價(jia)導(dao)電(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效率有(you)直(zhi)接的(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其重返氣流。比(bi)電(dian)(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易(yi)放(fang)(fang)(fang)出(chu)，在(zai)(zai)塵(chen)(chen)(chen)層之間(jian)形(xing)成電(dian)(dian)(dian)(dian)壓梯度(du)會產生局部(bu)擊穿和放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造成除(chu)塵(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器的(de)(de)基(ji)本原理(li)(li)是利用電(dian)(dian)力(li)捕集煙氣(qi)中的(de)(de)粉(fen)(fen)塵(chen)，主要(yao)包括以下四(si)個相(xiang)互有關的(de)(de)物理(li)(li)過程: (1) 氣(qi)體(ti)(ti)的(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)(de)荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉(fen)(fen)塵(chen)向(xiang)電(dian)(dian)極移動(dong)。(4) 荷(he)(he)電(dian)(dian)粉(fen)(fen)塵(chen)的(de)(de)捕集。
