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(shi)靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化法(fa)來(lai)收(shou)捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)粉塵，它(ta)的(de)(de)凈(jing)化工作(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和沉淀兩個系統來(lai)完成的(de)(de)，當含塵氣(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人氣(qi)(qi)(qi)刺叭時，含塵氣(qi)(qi)(qi)體(ti)(ti)(ti)受(shou)到氣(qi)(qi)(qi)流(liu)分(fen)布板以(yi)及(ji)折流(liu)板的(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)流(liu)能較均勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流(liu)速度迅(xun)速降低，其中有些較重的(de)(de)塵粒便失去速度而(er)沉降下來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵氣(qi)(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通人高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中存(cun)在(zai)(zai)大量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵結合(he)起來(lai)，使塵粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用下趨向本設(she)(she)備陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)(she)備采用負高壓(ya)制)和陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉積在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)，通過設(she)(she)備陰陽極(ji)(ji)(ji)(ji)振打系統的(de)(de)振打，使沉積在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)的(de)(de)粉塵振落(luo)，進(jin)人集灰斗 通過排(pai)灰裝置放出，回收(shou)有物(wu)料，被(bei))凈(jing)化的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排(pai)入大氣(qi)(qi)(qi)。

工作(zuo)原(yuan)理(li)

靜電(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)工作(zuo)原理是利用高(gao)壓電(dian)(dian)場使煙氣發生電(dian)(dian)離，氣流中的(de)粉塵(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作(zuo)用下(xia)與氣流分離。負極(ji)(ji)(ji)由(you)不同斷面形狀的(de)金屬(shu)導(dao)線制成，叫放(fang)(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不同幾何形狀的(de)金屬(shu)板制成，叫集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)性(xing)能受(shou)粉塵(chen)(chen)性(xing)質、設(she)備(bei)構造(zao)和煙氣流速等三個因素的(de)影(ying)響。粉塵(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)阻是評價導(dao)電(dian)(dian)性(xing)的(de)指(zhi)標，它對除(chu)塵(chen)(chen)效率(lv)有直(zhi)接的(de)影(ying)響。比(bi)(bi)電(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難(nan)以保持在(zai)集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)上，致使其重返(fan)氣流。比(bi)(bi)電(dian)(dian)阻過(guo)高(gao)，到達集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)的(de)塵(chen)(chen)粒電(dian)(dian)荷不易放(fang)(fang)出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)壓梯度會(hui)產生局(ju)部擊穿(chuan)和放(fang)(fang)電(dian)(dian)現象。這(zhe)些情(qing)況都會(hui)造(zao)成除(chu)塵(chen)(chen)效率(lv)下(xia)降。

電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)基本原理是(shi)利用電(dian)(dian)(dian)力捕集(ji)煙(yan)氣(qi)中的(de)(de)粉(fen)(fen)塵(chen)(chen)，主(zhu)要包括以下四(si)個相互有關的(de)(de)物理過程(cheng): (1) 氣(qi)體(ti)的(de)(de)電(dian)(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)(de)捕集(ji)。
