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)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢氣(qi)(qi)(qi)中(zhong)的(de)粉塵(chen)(chen)，它(ta)的(de)凈化(hua)工作(zuo)上要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)淀兩個系(xi)(xi)統來完成的(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受(shou)到(dao)氣(qi)(qi)(qi)流(liu)(liu)分(fen)布板(ban)以及折流(liu)(liu)板(ban)的(de)調整(zheng)后(hou)，使(shi)(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均勻地進人(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷(duan)面擴(kuo)大(da)的(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其(qi)中(zhong)有些較重的(de)塵(chen)(chen)粒便失去速度而沉(chen)降下來。進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存(cun)在大(da)量的(de)電(dian)(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)(dian)子和(he)離子與進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)粉塵(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)力(li)的(de)作(zuo)用(yong)下趨向本設(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備采用(yong)負(fu)(fu)高(gao)壓制)和(he)陰(yin)(yin)極(ji)(ji)(負(fu)(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分(fen)別沉(chen)積在相應的(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過(guo)設(she)備陰(yin)(yin)陽(yang)極(ji)(ji)振打系(xi)(xi)統的(de)振打，使(shi)(shi)沉(chen)積在陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)粉塵(chen)(chen)振落，進人(ren)集灰(hui)斗 通(tong)過(guo)排灰(hui)裝置放出，回收有物料，被)凈化(hua)的(de)氣(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作原理是利用高壓電(dian)(dian)場使煙氣(qi)發生(sheng)電(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)(zai)電(dian)(dian)場作用下與(yu)氣(qi)流(liu)(liu)分離。負極由(you)(you)不同(tong)(tong)斷面形狀(zhuang)的(de)(de)金屬(shu)導線制(zhi)成(cheng)，叫放電(dian)(dian)電(dian)(dian)極。正極由(you)(you)不同(tong)(tong)幾何形狀(zhuang)的(de)(de)金屬(shu)板制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)極。靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構(gou)造和(he)煙氣(qi)流(liu)(liu)速等三個因素的(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)極上，致使其重(zhong)返氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)阻(zu)過高，到達(da)集塵(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不易放出，在(zai)(zai)塵(chen)(chen)(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)壓梯度會產生(sheng)局部(bu)擊穿和(he)放電(dian)(dian)現象。這些情(qing)況都(dou)會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵器的(de)基本原理是利用電(dian)(dian)力捕集煙氣(qi)中的(de)粉(fen)(fen)(fen)塵，主要包(bao)括以下四個(ge)相(xiang)互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)(dian)離。(2) 粉(fen)(fen)(fen)塵的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)(fen)(fen)塵向(xiang)電(dian)(dian)極(ji)移動。(4) 荷(he)電(dian)(dian)粉(fen)(fen)(fen)塵的(de)捕集。
