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(jing)電(dian)(dian)(dian)除塵(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣(qi)中(zhong)(zhong)的(de)(de)粉塵(chen)，它的(de)(de)凈化(hua)工作(zuo)(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉淀(dian)兩(liang)個系統(tong)來(lai)完成的(de)(de)，當含(han)(han)塵(chen)氣(qi)體進人(ren)氣(qi)刺(ci)叭時，含(han)(han)塵(chen)氣(qi)體受到氣(qi)流(liu)分(fen)布(bu)板以(yi)及折流(liu)板的(de)(de)調整后，使氣(qi)流(liu)能(neng)較均勻地進人(ren)電(dian)(dian)(dian)場(chang)。在橫斷面擴大的(de)(de)作(zuo)(zuo)用下(xia)，氣(qi)流(liu)速度迅速降低，其中(zhong)(zhong)有些(xie)較重(zhong)的(de)(de)塵(chen)粒便失去(qu)速度而沉降下(xia)來(lai)。進人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含(han)(han)塵(chen)氣(qi)體由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)(yun)現(xian)象(xiang)，使氣(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)氣(qi)體中(zhong)(zhong)存(cun)在大量的(de)(de)電(dian)(dian)(dian)子和離子，這(zhe)些(xie)電(dian)(dian)(dian)子和離子與進人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)結合起來(lai)，使塵(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)場(chang)力(li)的(de)(de)作(zuo)(zuo)用下(xia)趨(qu)向(xiang)本設(she)備(bei)陽極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)采用負高(gao)壓制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分(fen)別沉積在相(xiang)應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設(she)備(bei)陰(yin)陽極(ji)(ji)振(zhen)打系統(tong)的(de)(de)振(zhen)打，使沉積在陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵(chen)振(zhen)落，進人(ren)集(ji)灰(hui)斗 通過排灰(hui)裝置放出，回(hui)收有物料，被)凈化(hua)的(de)(de)氣(qi)體排入大氣(qi)。

工(gong)作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)工(gong)作原理(li)是(shi)利用(yong)(yong)高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)(yong)下與氣(qi)流(liu)分離。負極(ji)由(you)(you)不同斷面形(xing)狀的(de)(de)(de)金(jin)屬導線(xian)制成，叫(jiao)(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)(you)不同幾何形(xing)狀的(de)(de)(de)金(jin)屬板制成，叫(jiao)(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)性(xing)(xing)能受粉塵(chen)(chen)性(xing)(xing)質、設備構造和(he)煙氣(qi)流(liu)速等三個因素的(de)(de)(de)影響。粉塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有直(zhi)接的(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)低(di)，塵(chen)(chen)粒難(nan)以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些(xie)情況(kuang)都會造成除塵(chen)(chen)效(xiao)率下降。

電除塵(chen)(chen)器(qi)的(de)(de)(de)基(ji)本原理是(shi)利用電力(li)捕(bu)集(ji)煙氣中的(de)(de)(de)粉(fen)塵(chen)(chen)，主要包(bao)括以(yi)下四(si)個相(xiang)互有(you)關的(de)(de)(de)物理過程: (1) 氣體(ti)的(de)(de)(de)電離。(2) 粉(fen)塵(chen)(chen)的(de)(de)(de)荷電。(3) 荷電粉(fen)塵(chen)(chen)向電極移(yi)動(dong)。(4) 荷電粉(fen)塵(chen)(chen)的(de)(de)(de)捕(bu)集(ji)。
