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)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈化(hua)工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩個系(xi)統來(lai)完成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)(qi)刺(ci)叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)(qi)流(liu)分布板以(yi)及(ji)折流(liu)板的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)流(liu)能較均(jun)勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫(heng)斷面擴大(da)(da)的(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)流(liu)速度迅(xun)速降低，其(qi)中有些(xie)較重(zhong)的(de)(de)塵(chen)(chen)粒便失去速度而沉降下(xia)來(lai)。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在(zai)(zai)(zai)大(da)(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與(yu)進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)結合起來(lai)，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)作(zuo)用下(xia)趨向(xiang)本(ben)設(she)備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備采用負(fu)高壓制(zhi))和陰(yin)(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設(she)備陰(yin)(yin)陽極(ji)(ji)振(zhen)打(da)系(xi)統的(de)(de)振(zhen)打(da)，使沉積在(zai)(zai)(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵(chen)(chen)振(zhen)落(luo)，進人(ren)集(ji)灰(hui)斗(dou) 通過排(pai)灰(hui)裝置放出(chu)(chu)，回收有物料(liao)，被)凈化(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入大(da)(da)氣(qi)(qi)(qi)。

工作(zuo)原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)的(de)(de)工(gong)作(zuo)原理(li)是利用高壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣發(fa)生電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣流(liu)(liu)分離。負極(ji)由不同(tong)斷面(mian)形(xing)狀的(de)(de)金屬(shu)導(dao)線制(zhi)成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何(he)形(xing)狀的(de)(de)金屬(shu)板制(zhi)成，叫集(ji)(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)的(de)(de)性能受(shou)粉(fen)塵(chen)性質(zhi)、設備(bei)構造(zao)和煙氣流(liu)(liu)速等(deng)三(san)個因素的(de)(de)影響。粉(fen)塵(chen)的(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)效率有(you)直接的(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)粒難以保持在(zai)集(ji)(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣流(liu)(liu)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集(ji)(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)層(ceng)之(zhi)間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度會(hui)產(chan)生局(ju)部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造(zao)成除塵(chen)效率下降。

電(dian)(dian)除塵器的(de)(de)基本原(yuan)理是利用電(dian)(dian)力捕集(ji)煙氣中(zhong)的(de)(de)粉(fen)塵，主(zhu)要(yao)包括以下四個(ge)相互有關的(de)(de)物理過程: (1) 氣體的(de)(de)電(dian)(dian)離(li)。(2) 粉(fen)塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵的(de)(de)捕集(ji)。
