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(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來收(shou)捕(bu)廢氣(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工作上要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉(chen)淀兩個系(xi)統(tong)(tong)來完成(cheng)的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)受到(dao)氣(qi)流(liu)分布板以(yi)及折流(liu)板的(de)(de)(de)(de)調(diao)整后(hou)，使氣(qi)流(liu)能較均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大的(de)(de)(de)(de)作用下(xia)，氣(qi)流(liu)速度(du)迅速降低，其中有些較重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失(shi)去速度(du)而沉(chen)降下(xia)來。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)中存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合起來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下(xia)趨向本設備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)采用負高(gao)壓制)和陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)(guo)設備(bei)陰陽極(ji)(ji)(ji)振(zhen)打(da)系(xi)統(tong)(tong)的(de)(de)(de)(de)振(zhen)打(da)，使沉(chen)積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)集灰(hui)斗(dou) 通過(guo)(guo)排灰(hui)裝(zhuang)置(zhi)放(fang)出(chu)，回收(shou)有物(wu)料(liao)，被)凈化(hua)的(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)排入(ru)大氣(qi)。

工作原理

靜(jing)電(dian)除(chu)塵(chen)器的(de)(de)工作原(yuan)理是利用高壓(ya)電(dian)場使(shi)煙氣(qi)(qi)(qi)發生電(dian)離(li)，氣(qi)(qi)(qi)流(liu)(liu)中的(de)(de)粉塵(chen)荷電(dian)在(zai)電(dian)場作用下與氣(qi)(qi)(qi)流(liu)(liu)分(fen)離(li)。負極(ji)(ji)(ji)(ji)由(you)不同(tong)斷面形狀的(de)(de)金(jin)屬導線制成，叫放(fang)(fang)電(dian)電(dian)極(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)由(you)不同(tong)幾何形狀的(de)(de)金(jin)屬板(ban)制成，叫集(ji)塵(chen)電(dian)極(ji)(ji)(ji)(ji)。靜(jing)電(dian)除(chu)塵(chen)器的(de)(de)性能受粉塵(chen)性質、設備構造和煙氣(qi)(qi)(qi)流(liu)(liu)速(su)等(deng)三(san)個(ge)因(yin)素(su)的(de)(de)影(ying)響。粉塵(chen)的(de)(de)比電(dian)阻(zu)(zu)是評(ping)價(jia)導電(dian)性的(de)(de)指標，它對除(chu)塵(chen)效(xiao)(xiao)率有直接的(de)(de)影(ying)響。比電(dian)阻(zu)(zu)過低，塵(chen)粒難以保持在(zai)集(ji)塵(chen)電(dian)極(ji)(ji)(ji)(ji)上，致(zhi)使(shi)其(qi)重返氣(qi)(qi)(qi)流(liu)(liu)。比電(dian)阻(zu)(zu)過高，到達集(ji)塵(chen)電(dian)極(ji)(ji)(ji)(ji)的(de)(de)塵(chen)粒電(dian)荷不易放(fang)(fang)出，在(zai)塵(chen)層之(zhi)間形成電(dian)壓(ya)梯度(du)會(hui)(hui)產(chan)生局部擊穿和放(fang)(fang)電(dian)現象。這些情(qing)況(kuang)都會(hui)(hui)造成除(chu)塵(chen)效(xiao)(xiao)率下降。

電除塵(chen)器的(de)(de)基本原理是利用電力捕集煙氣中的(de)(de)粉(fen)(fen)塵(chen)，主要包括以下四個相互有關的(de)(de)物理過程(cheng): (1) 氣體的(de)(de)電離。(2) 粉(fen)(fen)塵(chen)的(de)(de)荷(he)(he)電。(3) 荷(he)(he)電粉(fen)(fen)塵(chen)向電極(ji)移動。(4) 荷(he)(he)電粉(fen)(fen)塵(chen)的(de)(de)捕集。
