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)(dian)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢(fei)氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)(de)凈化(hua)工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀(dian)兩(liang)個系(xi)統(tong)來完成的(de)(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)進人氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)分(fen)(fen)布板以及折流(liu)板的(de)(de)(de)(de)(de)調整后(hou)，使(shi)(shi)氣(qi)(qi)(qi)流(liu)能(neng)較(jiao)均勻地進人電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫斷面擴大的(de)(de)(de)(de)(de)作(zuo)用下(xia)(xia)(xia)，氣(qi)(qi)(qi)流(liu)速度迅(xun)速降低，其中(zhong)有(you)些較(jiao)重的(de)(de)(de)(de)(de)塵(chen)粒(li)(li)便(bian)失去速度而沉降下(xia)(xia)(xia)來。進人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存(cun)在(zai)(zai)(zai)大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離子，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子和(he)離子與(yu)進人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉塵(chen)結(jie)合起來，使(shi)(shi)塵(chen)粒(li)(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)(li)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)(de)(de)作(zuo)用下(xia)(xia)(xia)趨向本設備陽(yang)極(ji)(正極(ji)、本設備采(cai)用負高壓制)和(he)陰(yin)(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子分(fen)(fen)別沉積在(zai)(zai)(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)過設備陰(yin)(yin)陽(yang)極(ji)振打系(xi)統(tong)的(de)(de)(de)(de)(de)振打，使(shi)(shi)沉積在(zai)(zai)(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)粉塵(chen)振落，進人集灰(hui)斗 通(tong)過排(pai)灰(hui)裝置放出，回收有(you)物料，被(bei))凈化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)(qi)。

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作原(yuan)理(li)是利用高壓電(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)(qi)發生(sheng)(sheng)電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用下(xia)與(yu)氣(qi)(qi)流(liu)分離。負極由(you)不(bu)同斷面(mian)形狀的(de)(de)(de)金屬導線制成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不(bu)同幾何形狀的(de)(de)(de)金屬板制成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受(shou)粉塵(chen)(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)(qi)流(liu)速等三個因素的(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)率有直(zhi)接的(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)(chen)粒難以保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使(shi)其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)(sheng)局部擊(ji)穿和放(fang)(fang)電(dian)(dian)(dian)現(xian)象。這(zhe)些情況都會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)率下(xia)降。
