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(jing)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)是以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法(fa)來收捕廢氣(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)凈(jing)(jing)化(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀兩(liang)個系統來完(wan)成的(de)(de)(de)，當含塵(chen)氣(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分布(bu)板以(yi)及(ji)折流(liu)(liu)板的(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流(liu)(liu)能較均(jun)勻地進人(ren)電(dian)(dian)(dian)(dian)場。在橫斷面(mian)擴大(da)的(de)(de)(de)作(zuo)用下，氣(qi)(qi)流(liu)(liu)速(su)度(du)迅速(su)降低(di)，其中有(you)些較重的(de)(de)(de)塵(chen)粒(li)便失去速(su)度(du)而沉(chen)降下來。進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離子(zi)與(yu)進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)結合起來，使(shi)(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒(li)在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用下趨向(xiang)本(ben)設備(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)設備(bei)采(cai)用負高壓制(zhi))和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過(guo)設備(bei)陰陽極(ji)(ji)振(zhen)打系統的(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)振(zhen)落(luo)，進人(ren)集灰斗(dou) 通過(guo)排灰裝置(zhi)放出，回收有(you)物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作原(yuan)理(li)是利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)粉(fen)(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作用下(xia)(xia)與(yu)氣(qi)流(liu)分(fen)離。負(fu)極(ji)由(you)不同斷面形(xing)狀的(de)金屬導線制(zhi)成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形(xing)狀的(de)金屬板(ban)制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性(xing)能受(shou)粉(fen)(fen)塵(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)流(liu)速等三(san)個因素的(de)影響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性(xing)的(de)指標，它(ta)對(dui)除塵(chen)(chen)(chen)效(xiao)率有直接的(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)難以(yi)保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使(shi)其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部(bu)擊(ji)穿和放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造成(cheng)除塵(chen)(chen)(chen)效(xiao)率下(xia)(xia)降。
