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)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)粉塵(chen)(chen)(chen)(chen)，它的(de)凈(jing)化(hua)工(gong)作上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉(chen)淀(dian)兩個系統來(lai)完成的(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流(liu)分布板以(yi)及(ji)折流(liu)板的(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)流(liu)能較均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)作用下，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降(jiang)低，其中(zhong)有些較重的(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速(su)度而(er)沉(chen)降(jiang)下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人(ren)高(gao)壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)(qi)(qi)體中(zhong)存在(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉塵(chen)(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作用下趨向本設(she)備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)采用負(fu)高(gao)壓(ya)制)和陰(yin)(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在(zai)相應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備(bei)陰(yin)(yin)陽(yang)極(ji)(ji)振打系統的(de)振打，使(shi)沉(chen)積(ji)在(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)粉塵(chen)(chen)(chen)(chen)振落，進(jin)(jin)人(ren)集灰斗 通過排灰裝置放出，回收有物料，被)凈(jing)化(hua)的(de)氣(qi)(qi)(qi)體排入大(da)氣(qi)(qi)(qi)。

工作原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)工(gong)作原理是利用(yong)(yong)高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用(yong)(yong)下與氣(qi)流(liu)分離。負極(ji)由不(bu)同斷面形狀(zhuang)的(de)(de)(de)(de)金(jin)屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形狀(zhuang)的(de)(de)(de)(de)金(jin)屬板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)性能(neng)受(shou)粉(fen)塵(chen)(chen)性質(zhi)、設備構造和煙氣(qi)流(liu)速等三個因素的(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指標(biao)，它對除塵(chen)(chen)效率有直(zhi)接的(de)(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以(yi)保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，致使其重(zhong)返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會(hui)(hui)造成(cheng)除塵(chen)(chen)效率下降。

電(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)基(ji)本原理(li)是(shi)利用電(dian)力(li)捕集煙氣(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)，主(zhu)要包括以下四個(ge)相互有關(guan)的(de)(de)(de)物理(li)過程: (1) 氣(qi)體(ti)的(de)(de)(de)電(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)(chen)向電(dian)極移(yi)動(dong)。(4) 荷電(dian)粉(fen)塵(chen)(chen)的(de)(de)(de)捕集。
