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)除塵(chen)(chen)(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)(hua)法來(lai)(lai)(lai)收(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈化(hua)(hua)(hua)工作(zuo)上(shang)(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉淀兩個(ge)系(xi)統來(lai)(lai)(lai)完成的(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)(ren)(ren)氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流分(fen)布板以(yi)及(ji)折流板的(de)(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)流能較均(jun)勻地進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷(duan)面擴大(da)的(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流速度迅速降低(di)，其中有(you)些較重的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)(li)便失(shi)去速度而沉降下來(lai)(lai)(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)(tong)(tong)人(ren)(ren)(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附(fu)近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離子，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)子和離子與進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來(lai)(lai)(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒(li)(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用下趨向本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用負高壓(ya)制)和陰(yin)極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子分(fen)別沉積在(zai)(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通(tong)(tong)(tong)過(guo)設備(bei)陰(yin)陽極(ji)振打系(xi)統的(de)(de)(de)振打，使(shi)沉積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振落，進人(ren)(ren)(ren)集灰斗(dou) 通(tong)(tong)(tong)過(guo)排(pai)灰裝(zhuang)置放(fang)出，回收(shou)有(you)物(wu)料(liao)，被)凈化(hua)(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)工(gong)作(zuo)原理是利用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)粉塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與(yu)氣(qi)(qi)流(liu)分離。負極(ji)由(you)不同斷(duan)面形(xing)狀的(de)金屬導線(xian)制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形(xing)狀的(de)金屬板制成，叫(jiao)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)性(xing)能受(shou)粉塵(chen)性(xing)質、設備構造和(he)煙氣(qi)(qi)流(liu)速等三個因素的(de)影響(xiang)。粉塵(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指(zhi)標(biao)，它(ta)對除(chu)塵(chen)效(xiao)率(lv)有直(zhi)接的(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)粒難以保(bao)持在(zai)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易(yi)放(fang)出，在(zai)塵(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會產生局部擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都會造成除(chu)塵(chen)效(xiao)率(lv)下降。

電(dian)除塵(chen)器(qi)的基本原理是利用電(dian)力捕集煙氣中的粉(fen)塵(chen)，主要包括以下四個相(xiang)互(hu)有(you)關的物理過程: (1) 氣體(ti)的電(dian)離。(2) 粉(fen)塵(chen)的荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)的捕集。
