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(wo)式靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)化法來收(shou)捕廢(fei)氣中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)凈(jing)化工作上要(yao)是依靠電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)和沉淀兩個系統來完(wan)成的(de)(de)，當含塵(chen)(chen)(chen)氣體進人氣刺叭時，含塵(chen)(chen)(chen)氣體受到氣流(liu)分布板(ban)以(yi)及(ji)折流(liu)板(ban)的(de)(de)調整后(hou)，使氣流(liu)能(neng)較(jiao)均勻地進人電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大的(de)(de)作用下，氣流(liu)速(su)度迅(xun)速(su)降(jiang)低，其中(zhong)有些(xie)較(jiao)重(zhong)的(de)(de)塵(chen)(chen)(chen)粒(li)便失(shi)去速(su)度而沉降(jiang)下來。進人電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)含塵(chen)(chen)(chen)氣體由(you)于電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)通人高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)現象，使氣體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣體中(zhong)存在(zai)(zai)大量(liang)的(de)(de)電(dian)(dian)(dian)(dian)子和離(li)子，這些(xie)電(dian)(dian)(dian)(dian)子和離(li)子與進人電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)結合(he)起來，使塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用下趨向(xiang)本(ben)設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備(bei)采用負(fu)高壓制)和陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出(chu)(chu)電(dian)(dian)(dian)(dian)子分別沉積在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設備(bei)陰(yin)陽(yang)極(ji)(ji)振打系統的(de)(de)振打，使沉積在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)振落，進人集灰斗 通過排灰裝(zhuang)置放出(chu)(chu)，回收(shou)有物(wu)料(liao)，被)凈(jing)化的(de)(de)氣體排入大氣。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作(zuo)原(yuan)理是利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發(fa)生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與氣流分離。負極(ji)(ji)(ji)由不(bu)同(tong)(tong)斷面形狀(zhuang)的(de)(de)金屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不(bu)同(tong)(tong)幾(ji)何形狀(zhuang)的(de)(de)金屬板制成(cheng)，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)性質、設備構造(zao)(zao)和煙氣流速等三個因素的(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)效率(lv)有直接的(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)難以保持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，致使其(qi)重返(fan)氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放出，在(zai)塵(chen)(chen)層(ceng)之間形成(cheng)電(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)現象。這(zhe)些(xie)情況都(dou)會(hui)(hui)造(zao)(zao)成(cheng)除(chu)塵(chen)(chen)效率(lv)下(xia)降(jiang)。

電(dian)(dian)除塵(chen)(chen)器(qi)的(de)基本(ben)原理是利(li)用電(dian)(dian)力(li)捕集煙氣中(zhong)的(de)粉(fen)塵(chen)(chen)，主(zhu)要包(bao)括(kuo)以(yi)下四個(ge)相互(hu)有關的(de)物理過(guo)程(cheng): (1) 氣體(ti)的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集。
