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)除塵(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)凈化法來收(shou)捕廢(fei)氣(qi)(qi)(qi)中(zhong)(zhong)(zhong)的(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)凈化工作上要是(shi)依(yi)靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉淀兩個系統(tong)來完(wan)成的(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)體進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)刺(ci)叭(ba)時，含塵(chen)(chen)氣(qi)(qi)(qi)體受(shou)到氣(qi)(qi)(qi)流分布板(ban)以(yi)及(ji)折流板(ban)的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流能較均勻(yun)地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場。在(zai)橫(heng)斷面擴(kuo)大的(de)(de)作用(yong)(yong)下(xia)(xia)，氣(qi)(qi)(qi)流速度迅速降(jiang)低，其(qi)中(zhong)(zhong)(zhong)有些(xie)較重的(de)(de)塵(chen)(chen)粒(li)便失(shi)去速度而沉降(jiang)下(xia)(xia)來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人(ren)(ren)高(gao)(gao)壓直(zhi)流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)(yun)現象(xiang)，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)體中(zhong)(zhong)(zhong)存(cun)在(zai)大量(liang)的(de)(de)電(dian)(dian)(dian)子和離(li)子，這些(xie)電(dian)(dian)(dian)子和離(li)子與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場力的(de)(de)作用(yong)(yong)下(xia)(xia)趨向本設(she)備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)采用(yong)(yong)負高(gao)(gao)壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)子分別沉積(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通過(guo)設(she)備(bei)陰陽(yang)極(ji)(ji)振打系統(tong)的(de)(de)振打，使(shi)沉積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)(chen)振落，進(jin)(jin)人(ren)(ren)集灰斗 通過(guo)排(pai)灰裝置放出，回收(shou)有物料，被)凈化的(de)(de)氣(qi)(qi)(qi)體排(pai)入大氣(qi)(qi)(qi)。

工作原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)工作(zuo)原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流(liu)分離(li)。負極(ji)由不同(tong)(tong)斷(duan)面(mian)形狀的(de)金(jin)(jin)屬導線制成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同(tong)(tong)幾何形狀的(de)金(jin)(jin)屬板制成，叫集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設備(bei)構(gou)造和(he)(he)煙氣(qi)流(liu)速等(deng)三個因素(su)的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評(ping)價導電(dian)(dian)(dian)(dian)性(xing)(xing)的(de)指標，它(ta)對除塵(chen)(chen)(chen)效率有直接(jie)的(de)影響。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)粒難(nan)以保持(chi)在(zai)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過高(gao)，到達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)層(ceng)之間(jian)形成電(dian)(dian)(dian)(dian)壓梯(ti)度會(hui)產生局(ju)部擊(ji)穿和(he)(he)放(fang)(fang)電(dian)(dian)(dian)(dian)現象(xiang)。這些情況都(dou)會(hui)造成除塵(chen)(chen)(chen)效率下降。

電(dian)除塵(chen)器的(de)(de)(de)基本原理是利用電(dian)力捕集(ji)煙氣(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)，主(zhu)要包括以下四個相互有關的(de)(de)(de)物(wu)理過程: (1) 氣(qi)(qi)體的(de)(de)(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)的(de)(de)(de)捕集(ji)。
