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)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢氣中(zhong)(zhong)的(de)粉塵(chen)，它的(de)凈化工(gong)作(zuo)上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀兩個系統(tong)來完成的(de)，當含塵(chen)氣體(ti)(ti)(ti)進人(ren)氣刺叭時(shi)，含塵(chen)氣體(ti)(ti)(ti)受到氣流分布板(ban)以及(ji)折流板(ban)的(de)調整(zheng)后，使(shi)(shi)氣流能較均(jun)勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在橫斷(duan)面擴大(da)的(de)作(zuo)用(yong)下(xia)，氣流速度迅速降低，其中(zhong)(zhong)有(you)些(xie)較重的(de)塵(chen)粒便失去速度而沉(chen)降下(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)含塵(chen)氣體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高(gao)壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)氣體(ti)(ti)(ti)中(zhong)(zhong)存在大(da)量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)子與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)粉塵(chen)結合起來，使(shi)(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)作(zuo)用(yong)下(xia)趨向本設備陽極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)負高(gao)壓(ya)制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在相應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設備陰陽極(ji)(ji)振打系統(tong)的(de)振打，使(shi)(shi)沉(chen)積在陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)粉塵(chen)振落(luo)，進人(ren)集灰(hui)斗 通過排灰(hui)裝(zhuang)置放出，回收(shou)有(you)物料，被)凈化的(de)氣體(ti)(ti)(ti)排入大(da)氣。

工作原(yuan)理(li)

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)工作(zuo)原(yuan)理是(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣流中(zhong)的(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與(yu)氣流分(fen)離(li)。負極(ji)(ji)由不同斷面形(xing)(xing)狀的(de)金(jin)屬(shu)導線制成，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾(ji)何形(xing)(xing)狀的(de)金(jin)屬(shu)板制成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)性能受粉塵(chen)(chen)(chen)性質、設備構造(zao)和(he)煙(yan)氣流速等(deng)三個因素(su)的(de)影響。粉塵(chen)(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對(dui)除(chu)塵(chen)(chen)(chen)效率有直接的(de)影響。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重(zhong)返氣流。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到(dao)達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在(zai)塵(chen)(chen)(chen)層之(zhi)間(jian)形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會(hui)產(chan)生局(ju)部(bu)擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些(xie)情況(kuang)都(dou)會(hui)造(zao)成除(chu)塵(chen)(chen)(chen)效率下(xia)降。

電(dian)(dian)除塵(chen)器的(de)(de)基本(ben)原理(li)是利用電(dian)(dian)力捕集煙(yan)氣(qi)中的(de)(de)粉(fen)塵(chen)，主要包括以下四個(ge)相互有關的(de)(de)物理(li)過程(cheng): (1) 氣(qi)體的(de)(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)(de)荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉(fen)塵(chen)向(xiang)電(dian)(dian)極移動。(4) 荷(he)(he)電(dian)(dian)粉(fen)塵(chen)的(de)(de)捕集。
