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(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收(shou)捕廢(fei)氣(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)工作上(shang)要(yao)是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩(liang)個(ge)系(xi)統(tong)來(lai)完成的(de)(de)(de)(de)，當含(han)(han)塵(chen)(chen)氣(qi)體(ti)進人(ren)(ren)氣(qi)刺叭(ba)時，含(han)(han)塵(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)分(fen)布板以及(ji)折流(liu)(liu)板的(de)(de)(de)(de)調整(zheng)后，使(shi)氣(qi)流(liu)(liu)能較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷(duan)面(mian)擴大(da)的(de)(de)(de)(de)作用(yong)下，氣(qi)流(liu)(liu)速度迅(xun)速降低，其中有些較重的(de)(de)(de)(de)塵(chen)(chen)粒便失去速度而沉降下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)(han)塵(chen)(chen)氣(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)(tong)人(ren)(ren)高(gao)壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)體(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)離(li)子，這(zhe)些電(dian)(dian)(dian)(dian)子和(he)離(li)子與進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用(yong)下趨向本設備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)采(cai)用(yong)負(fu)高(gao)壓(ya)制)和(he)陰(yin)(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子分(fen)別沉積在(zai)(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)(tong)過設備(bei)陰(yin)(yin)陽(yang)極(ji)(ji)(ji)振(zhen)打系(xi)統(tong)的(de)(de)(de)(de)振(zhen)打，使(shi)沉積在(zai)(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進人(ren)(ren)集灰(hui)斗 通(tong)(tong)過排(pai)(pai)灰(hui)裝(zhuang)置(zhi)放出(chu)，回(hui)收(shou)有物(wu)料，被(bei))凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)體(ti)排(pai)(pai)入大(da)氣(qi)。

工作(zuo)原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原理是(shi)利(li)用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣流中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣流分(fen)離(li)。負(fu)極(ji)由(you)不同斷面形狀的(de)(de)金屬導線制(zhi)成，叫(jiao)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由(you)不同幾何形狀的(de)(de)金屬板制(zhi)成，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設備構造和煙(yan)氣流速等(deng)三(san)個因素(su)的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)粒難(nan)以保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)出(chu)，在(zai)塵(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局(ju)部擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會造成除(chu)塵(chen)(chen)(chen)效率(lv)下降(jiang)。

電(dian)除塵(chen)(chen)(chen)器(qi)的基本原理(li)是利用電(dian)力捕(bu)集煙氣中的粉塵(chen)(chen)(chen)，主要(yao)包括以下(xia)四個相互有(you)關的物理(li)過程: (1) 氣體的電(dian)離(li)。(2) 粉塵(chen)(chen)(chen)的荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉塵(chen)(chen)(chen)向電(dian)極(ji)移(yi)動(dong)。(4) 荷(he)(he)電(dian)粉塵(chen)(chen)(chen)的捕(bu)集。
