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)式靜電(dian)(dian)(dian)除塵(chen)器是以(yi)靜電(dian)(dian)(dian)凈化(hua)法來收捕(bu)廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)，它的(de)(de)(de)(de)(de)(de)凈化(hua)工作上要是依(yi)靠電(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩個系(xi)統來完成的(de)(de)(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)刺(ci)叭時(shi)，含塵(chen)氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流分(fen)(fen)布板以(yi)及(ji)折流板的(de)(de)(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流能較(jiao)均勻地(di)進人(ren)(ren)電(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴(kuo)大(da)的(de)(de)(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)流速(su)度迅速(su)降(jiang)低，其中(zhong)有些較(jiao)重的(de)(de)(de)(de)(de)(de)塵(chen)粒便失去速(su)度而(er)沉降(jiang)下(xia)來。進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通(tong)(tong)人(ren)(ren)高壓(ya)(ya)直流電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)存(cun)在(zai)(zai)大(da)量(liang)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)結合起(qi)來，使(shi)塵(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)(de)作用下(xia)趨向本設備(bei)(bei)陽極(ji)(ji)(正極(ji)(ji)、本設備(bei)(bei)采用負高壓(ya)(ya)制(zhi))和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)分(fen)(fen)別(bie)沉積(ji)在(zai)(zai)相應(ying)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通(tong)(tong)過設備(bei)(bei)陰陽極(ji)(ji)振打(da)(da)系(xi)統的(de)(de)(de)(de)(de)(de)振打(da)(da)，使(shi)沉積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)振落，進人(ren)(ren)集灰斗 通(tong)(tong)過排(pai)灰裝(zhuang)置放出(chu)，回收有物(wu)料，被)凈化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)(qi)。

工(gong)作原(yuan)理

靜電(dian)(dian)(dian)除(chu)塵(chen)器的工作原理(li)是(shi)利用高(gao)壓電(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流中的粉(fen)塵(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流分離(li)。負極由不同(tong)(tong)斷面(mian)形(xing)狀的金(jin)屬(shu)導(dao)線(xian)制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不同(tong)(tong)幾何(he)形(xing)狀的金(jin)屬(shu)板制(zhi)成(cheng)，叫集(ji)塵(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)器的性(xing)能受粉(fen)塵(chen)性(xing)質、設(she)備構(gou)造和煙氣(qi)流速等三個因(yin)素的影(ying)響(xiang)。粉(fen)塵(chen)的比(bi)電(dian)(dian)(dian)阻是(shi)評價(jia)導(dao)電(dian)(dian)(dian)性(xing)的指標，它(ta)對除(chu)塵(chen)效率(lv)有直接(jie)的影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)粒難(nan)以保持(chi)在(zai)集(ji)塵(chen)電(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)流。比(bi)電(dian)(dian)(dian)阻過高(gao)，到達(da)集(ji)塵(chen)電(dian)(dian)(dian)極的塵(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產生局部(bu)擊穿(chuan)和放(fang)電(dian)(dian)(dian)現象。這些情(qing)況都會造成(cheng)除(chu)塵(chen)效率(lv)下(xia)降。

電(dian)除塵(chen)器的基本原(yuan)理是(shi)利用電(dian)力捕集(ji)煙氣中的粉塵(chen)，主(zhu)要(yao)包括(kuo)以(yi)下四個相互有關的物理過(guo)程: (1) 氣體(ti)的電(dian)離。(2) 粉塵(chen)的荷電(dian)。(3) 荷電(dian)粉塵(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉塵(chen)的捕集(ji)。
