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)除塵(chen)(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)凈(jing)(jing)化(hua)法來收(shou)捕廢氣(qi)中(zhong)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈(jing)(jing)化(hua)工(gong)作上要(yao)是(shi)依靠(kao)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀兩(liang)個系統來完成的(de)(de)(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進人氣(qi)刺叭(ba)時，含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)(liu)分布板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)(liu)能較均勻地進人電(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)(da)的(de)(de)(de)(de)(de)(de)作用(yong)下(xia)，氣(qi)流(liu)(liu)速(su)(su)度迅速(su)(su)降低(di)，其中(zhong)有(you)(you)些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失去(qu)速(su)(su)度而沉降下(xia)來。進人電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高(gao)壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)中(zhong)存(cun)在(zai)大(da)(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)與進人電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起(qi)來，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)作用(yong)下(xia)趨向(xiang)本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備(bei)采(cai)用(yong)負高(gao)壓制)和陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)(zi)分別沉積在(zai)相應(ying)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設(she)備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)(de)(de)(de)振(zhen)打(da)，使(shi)沉積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進人集(ji)灰斗 通過(guo)排(pai)灰裝置(zhi)放出，回(hui)收(shou)有(you)(you)物(wu)料(liao)，被)凈(jing)(jing)化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)排(pai)入(ru)大(da)(da)氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)工作原理是(shi)利用(yong)高壓電(dian)(dian)(dian)場(chang)使煙(yan)氣發生電(dian)(dian)(dian)離，氣流(liu)(liu)(liu)中的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用(yong)下與氣流(liu)(liu)(liu)分離。負極由不(bu)同斷面形狀的(de)金屬(shu)導線制(zhi)成，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不(bu)同幾何形狀的(de)金屬(shu)板制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造(zao)和煙(yan)氣流(liu)(liu)(liu)速等(deng)三個因素的(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性的(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率有直接的(de)影(ying)響(xiang)。比(bi)(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使其重返氣流(liu)(liu)(liu)。比(bi)(bi)電(dian)(dian)(dian)阻過高，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯度會(hui)(hui)產生局部(bu)擊穿和放(fang)電(dian)(dian)(dian)現象。這些情(qing)況都會(hui)(hui)造(zao)成除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率下降。

電(dian)除塵(chen)(chen)器的基本原理(li)是(shi)利用電(dian)力捕集(ji)煙(yan)氣(qi)中的粉(fen)塵(chen)(chen)，主要包括(kuo)以下四(si)個相互有關的物理(li)過程: (1) 氣(qi)體的電(dian)離。(2) 粉(fen)塵(chen)(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)(chen)向電(dian)極移(yi)動(dong)。(4) 荷(he)電(dian)粉(fen)塵(chen)(chen)的捕集(ji)。
