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。

臥式靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收(shou)捕(bu)廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈(jing)化工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系(xi)統(tong)來完成的(de)(de)(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分(fen)布板(ban)以(yi)及(ji)折流板(ban)的(de)(de)(de)(de)(de)(de)調整后(hou)，使(shi)(shi)氣(qi)(qi)(qi)流能較均勻(yun)地(di)進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面(mian)擴大(da)(da)的(de)(de)(de)(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)流速(su)度(du)迅速(su)降(jiang)(jiang)低，其(qi)中(zhong)有(you)些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)便失(shi)去(qu)速(su)度(du)而沉降(jiang)(jiang)下(xia)來。進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通人高壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存(cun)在(zai)大(da)(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)結合起(qi)來，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)作(zuo)用下(xia)趨(qu)向本(ben)設備陽(yang)(yang)極(ji)(正(zheng)極(ji)、本(ben)設備采用負(fu)高壓制(zhi))和(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉積在(zai)相(xiang)應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通過(guo)設備陰(yin)陽(yang)(yang)極(ji)振打系(xi)統(tong)的(de)(de)(de)(de)(de)(de)振打，使(shi)(shi)沉積在(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)振落，進(jin)(jin)人集灰(hui)(hui)斗 通過(guo)排(pai)(pai)灰(hui)(hui)裝(zhuang)置放出，回收(shou)有(you)物(wu)料，被)凈(jing)化的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)(pai)入大(da)(da)氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)工作原理是利用高壓(ya)電(dian)(dian)(dian)場使煙氣(qi)發(fa)生電(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣(qi)流(liu)分離。負極(ji)(ji)由不同斷面形狀的(de)(de)(de)金(jin)屬(shu)導線制(zhi)成，叫放(fang)(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形狀的(de)(de)(de)金(jin)屬(shu)板制(zhi)成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)性能(neng)受粉(fen)塵(chen)(chen)性質、設備構造(zao)和(he)煙氣(qi)流(liu)速等三個因素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性的(de)(de)(de)指標，它對除(chu)塵(chen)(chen)效率有直(zhi)接的(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以保(bao)持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其重(zhong)返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)(fang)(fang)出(chu)，在塵(chen)(chen)層之間形成電(dian)(dian)(dian)壓(ya)梯(ti)度會(hui)產生局部擊穿和(he)放(fang)(fang)(fang)電(dian)(dian)(dian)現象。這(zhe)些情況都會(hui)造(zao)成除(chu)塵(chen)(chen)效率下降。

電除塵器的基本原理(li)是利用電力捕集(ji)煙氣中的粉(fen)塵，主要包(bao)括以下四個相互(hu)有關的物理(li)過程: (1) 氣體的電離。(2) 粉(fen)塵的荷電。(3) 荷電粉(fen)塵向(xiang)電極移動(dong)。(4) 荷電粉(fen)塵的捕集(ji)。
