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)以靜電(dian)(dian)(dian)凈化(hua)法來(lai)(lai)收捕廢(fei)氣(qi)中的(de)粉塵(chen)(chen)，它的(de)凈化(hua)工作上(shang)要是(shi)依靠電(dian)(dian)(dian)暈極和沉淀(dian)兩個系統來(lai)(lai)完成(cheng)的(de)，當含塵(chen)(chen)氣(qi)體(ti)進(jin)人(ren)(ren)氣(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)體(ti)受(shou)到氣(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)調整后，使(shi)(shi)氣(qi)流(liu)(liu)能較(jiao)均(jun)勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大(da)的(de)作用(yong)下，氣(qi)流(liu)(liu)速(su)(su)(su)度迅(xun)速(su)(su)(su)降低，其中有些(xie)較(jiao)重(zhong)的(de)塵(chen)(chen)粒便失(shi)去速(su)(su)(su)度而沉降下來(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)含塵(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)暈極通(tong)(tong)人(ren)(ren)高(gao)壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈極附近產生電(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)氣(qi)體(ti)中存在(zai)(zai)大(da)量的(de)電(dian)(dian)(dian)子(zi)和離(li)子(zi)，這(zhe)些(xie)電(dian)(dian)(dian)子(zi)和離(li)子(zi)與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)粉塵(chen)(chen)結合起來(lai)(lai)，使(shi)(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)作用(yong)下趨向本(ben)設備(bei)陽極(正(zheng)極、本(ben)設備(bei)采(cai)用(yong)負(fu)高(gao)壓制(zhi))和陰(yin)極(負(fu)極) ， 釋(shi)放(fang)出電(dian)(dian)(dian)子(zi)分別(bie)沉積(ji)在(zai)(zai)相(xiang)應(ying)的(de)電(dian)(dian)(dian)極上(shang)，通(tong)(tong)過設備(bei)陰(yin)陽極振打系統的(de)振打，使(shi)(shi)沉積(ji)在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)極上(shang)的(de)粉塵(chen)(chen)振落，進(jin)人(ren)(ren)集(ji)灰斗 通(tong)(tong)過排灰裝置放(fang)出，回收有物料(liao)，被)凈化(hua)的(de)氣(qi)體(ti)排入大(da)氣(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)工作原理是利用高壓電(dian)(dian)(dian)場(chang)(chang)使煙(yan)氣發生電(dian)(dian)(dian)離，氣流中的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)(chang)作用下與(yu)氣流分離。負(fu)極(ji)(ji)由不同(tong)斷面形狀的(de)(de)金屬導(dao)線制(zhi)成(cheng)(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不同(tong)幾何形狀的(de)(de)金屬板制(zhi)成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)性(xing)能(neng)受粉(fen)(fen)塵(chen)(chen)(chen)性(xing)質、設(she)備構造和煙(yan)氣流速等(deng)三個因素的(de)(de)影(ying)響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)指標(biao)，它(ta)對除塵(chen)(chen)(chen)效率(lv)有直接(jie)的(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保(bao)持(chi)在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其重(zhong)返氣流。比(bi)電(dian)(dian)(dian)阻過高，到(dao)達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)壓梯度(du)會產生局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些(xie)情況都會造成(cheng)(cheng)除塵(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)除塵(chen)器的基本原理(li)(li)是利(li)用電(dian)(dian)力捕集煙氣中的粉(fen)(fen)塵(chen)，主要包括以下四個相互有關的物理(li)(li)過程: (1) 氣體(ti)的電(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵(chen)向(xiang)電(dian)(dian)極(ji)移(yi)動。(4) 荷電(dian)(dian)粉(fen)(fen)塵(chen)的捕集。
