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)除塵器是(shi)以靜電(dian)(dian)(dian)凈(jing)化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉(fen)(fen)塵，它的(de)(de)(de)凈(jing)化(hua)(hua)工作上要是(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)和沉淀兩(liang)個系(xi)統來(lai)完成的(de)(de)(de)，當含(han)塵氣(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)刺(ci)叭時，含(han)塵氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流(liu)分布(bu)板以及(ji)折流(liu)板的(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)流(liu)能較均(jun)勻地進人電(dian)(dian)(dian)場(chang)。在橫斷面擴大的(de)(de)(de)作用下，氣(qi)(qi)(qi)流(liu)速度迅(xun)速降(jiang)(jiang)低，其中有些較重的(de)(de)(de)塵粒(li)便(bian)失去速度而沉降(jiang)(jiang)下來(lai)。進人電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵氣(qi)(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)暈(yun)極(ji)通人高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在大量的(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)，這(zhe)些電(dian)(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)與進人電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)(fen)塵結(jie)合(he)起來(lai)，使(shi)塵粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵粒(li)在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下趨向本(ben)設(she)備陽極(ji)(正極(ji)、本(ben)設(she)備采用負高壓(ya)制)和陰(yin)極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)(zi)分別(bie)沉積在相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通過設(she)備陰(yin)陽極(ji)振打系(xi)統的(de)(de)(de)振打，使(shi)沉積在陰(yin)陽電(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉(fen)(fen)塵振落，進人集灰斗 通過排灰裝置放出(chu)，回收有物料(liao)，被)凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器的(de)(de)工作原理(li)是利(li)用(yong)高壓電(dian)(dian)場使煙(yan)氣(qi)(qi)發生電(dian)(dian)離(li)，氣(qi)(qi)流中的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作用(yong)下(xia)與氣(qi)(qi)流分離(li)。負極(ji)(ji)由(you)不同斷面形狀的(de)(de)金屬導線制成(cheng)，叫(jiao)(jiao)放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形狀的(de)(de)金屬板制成(cheng)，叫(jiao)(jiao)集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器的(de)(de)性(xing)能受粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)性(xing)質、設備(bei)構造(zao)和煙(yan)氣(qi)(qi)流速等(deng)三個因(yin)素(su)的(de)(de)影(ying)響。粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)(bi)電(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)性(xing)的(de)(de)指標，它(ta)對除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)率(lv)有直接(jie)的(de)(de)影(ying)響。比(bi)(bi)電(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)難以保持(chi)在集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)(qi)流。比(bi)(bi)電(dian)(dian)阻(zu)過高，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)荷(he)不易放(fang)出(chu)，在塵(chen)(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度會(hui)產生局部擊穿和放(fang)電(dian)(dian)現象。這(zhe)些情況(kuang)都會(hui)造(zao)成(cheng)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)率(lv)下(xia)降。

電(dian)除(chu)塵器的(de)基本(ben)原理是(shi)利用電(dian)力捕(bu)集(ji)煙氣(qi)中的(de)粉(fen)塵，主要包括以下四個相互有關(guan)的(de)物理過程: (1) 氣(qi)體(ti)的(de)電(dian)離。(2) 粉(fen)塵的(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉(fen)塵向(xiang)電(dian)極移動。(4) 荷(he)(he)電(dian)粉(fen)塵的(de)捕(bu)集(ji)。
