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)除塵(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收捕(bu)廢氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈(jing)(jing)化(hua)工作(zuo)上(shang)(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)和沉(chen)(chen)淀兩(liang)個系(xi)統(tong)來(lai)完成的(de)(de)，當含塵(chen)氣(qi)(qi)體(ti)進(jin)(jin)人氣(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)體(ti)受(shou)到(dao)氣(qi)(qi)流分(fen)布板以(yi)及(ji)折(zhe)流板的(de)(de)調(diao)整后，使(shi)(shi)氣(qi)(qi)流能(neng)較均勻地進(jin)(jin)人電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴(kuo)大(da)的(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流速度迅速降低，其中有些(xie)較重的(de)(de)塵(chen)粒(li)便失去速度而沉(chen)(chen)降下來(lai)。進(jin)(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)通人高壓直流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)現象，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)體(ti)中存在(zai)大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)(dian)子和離子與進(jin)(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)結合(he)起來(lai)，使(shi)(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下趨向本設(she)(she)備陽極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)(she)備采(cai)用(yong)負高壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)子分(fen)別(bie)沉(chen)(chen)積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)(shang)，通過設(she)(she)備陰陽極(ji)(ji)振打系(xi)統(tong)的(de)(de)振打，使(shi)(shi)沉(chen)(chen)積在(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)(shang)的(de)(de)粉(fen)塵(chen)振落，進(jin)(jin)人集灰(hui)斗 通過排灰(hui)裝置(zhi)放(fang)出(chu)，回收有物料(liao)，被)凈(jing)(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)工(gong)作(zuo)原理是(shi)利用(yong)高壓(ya)電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(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(yong)下與氣(qi)流(liu)分離(li)。負極(ji)(ji)由(you)不同斷面形(xing)狀的(de)(de)金(jin)屬(shu)導線制成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何(he)形(xing)狀的(de)(de)金(jin)屬(shu)板制成，叫集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設(she)備構(gou)造(zao)和煙(yan)氣(qi)流(liu)速等三個(ge)因素的(de)(de)影響(xiang)。粉(fen)塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它(ta)對除(chu)塵(chen)效率(lv)有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)粒難以保持(chi)在(zai)集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)高，到達集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易(yi)放(fang)出(chu)，在(zai)塵(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會產生局(ju)部(bu)擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況都會造(zao)成除(chu)塵(chen)效率(lv)下降。

電(dian)除塵器的(de)(de)基本(ben)原(yuan)理是利用電(dian)力(li)捕(bu)集煙氣中的(de)(de)粉(fen)塵，主要包括以下(xia)四個相互有關的(de)(de)物(wu)理過(guo)程: (1) 氣體的(de)(de)電(dian)離(li)。(2) 粉(fen)塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向(xiang)電(dian)極移動。(4) 荷電(dian)粉(fen)塵的(de)(de)捕(bu)集。
