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(shi)靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)，它的(de)凈化(hua)工作上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩(liang)個(ge)系統來完成(cheng)的(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流(liu)分布板(ban)以及折(zhe)流(liu)板(ban)的(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)能(neng)較均勻地進人電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)作用(yong)下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降低(di)，其(qi)中(zhong)有(you)些較重(zhong)的(de)塵(chen)(chen)(chen)粒(li)(li)便失去速度(du)而(er)沉降下(xia)來。進人電(dian)(dian)(dian)(dian)場的(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)暈極(ji)(ji)通人高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)(qi)(qi)體(ti)中(zhong)存在(zai)(zai)大量(liang)的(de)電(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進人電(dian)(dian)(dian)(dian)場的(de)粉(fen)塵(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力(li)的(de)作用(yong)下(xia)趨向本(ben)設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備采(cai)用(yong)負(fu)高壓制)和陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)(zai)相(xiang)應的(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備陰(yin)陽(yang)極(ji)(ji)振打(da)系統的(de)振打(da)，使沉積在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)粉(fen)塵(chen)(chen)(chen)振落，進人集灰(hui)斗 通過排(pai)灰(hui)裝置放出，回(hui)收有(you)物料，被)凈化(hua)的(de)氣(qi)(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)(de)(de)(de)(de)(de)工作原理是利(li)用高(gao)(gao)壓電(dian)(dian)場使(shi)煙氣(qi)發生(sheng)電(dian)(dian)離，氣(qi)流中的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用下與(yu)氣(qi)流分離。負極(ji)由不同斷面形(xing)狀(zhuang)的(de)(de)(de)(de)(de)(de)(de)金(jin)屬(shu)導(dao)(dao)線(xian)制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不同幾何形(xing)狀(zhuang)的(de)(de)(de)(de)(de)(de)(de)金(jin)屬(shu)板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)(de)(de)(de)(de)(de)性(xing)能(neng)受粉(fen)塵(chen)(chen)性(xing)質、設備構造(zao)(zao)和煙氣(qi)流速(su)等三個因素的(de)(de)(de)(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)(de)(de)(de)比(bi)電(dian)(dian)阻(zu)是評(ping)價導(dao)(dao)電(dian)(dian)性(xing)的(de)(de)(de)(de)(de)(de)(de)指(zhi)標，它對除(chu)(chu)塵(chen)(chen)效率有(you)直接的(de)(de)(de)(de)(de)(de)(de)影響。比(bi)電(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)極(ji)上(shang)，致(zhi)使(shi)其重返氣(qi)流。比(bi)電(dian)(dian)阻(zu)過高(gao)(gao)，到達集塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)荷不易(yi)放出(chu)，在(zai)塵(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)(dian)壓梯(ti)度會產(chan)生(sheng)局部擊穿和放電(dian)(dian)現象。這些情(qing)況(kuang)都(dou)會造(zao)(zao)成(cheng)除(chu)(chu)塵(chen)(chen)效率下降。

電除塵(chen)(chen)器的(de)基本原理是利(li)用電力(li)捕(bu)集(ji)(ji)煙氣中的(de)粉(fen)塵(chen)(chen)，主要(yao)包括以下四個(ge)相互有關(guan)的(de)物理過程: (1) 氣體的(de)電離(li)。(2) 粉(fen)塵(chen)(chen)的(de)荷電。(3) 荷電粉(fen)塵(chen)(chen)向電極移動(dong)。(4) 荷電粉(fen)塵(chen)(chen)的(de)捕(bu)集(ji)(ji)。
