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)(dian)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉(chen)淀(dian)兩(liang)個系統來完成(cheng)的(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進人氣(qi)(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)分(fen)布板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)能較均勻地進人電(dian)(dian)(dian)(dian)(dian)(dian)場。在橫(heng)斷面擴大(da)的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其中有些(xie)較重的(de)(de)(de)塵(chen)(chen)粒便失去速度而沉(chen)降下(xia)來。進人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高壓(ya)(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中存在大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與(yu)進人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下(xia)趨向本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本設(she)備(bei)采用(yong)負高壓(ya)(ya)制)和陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉(chen)積(ji)在相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設(she)備(bei)陰陽(yang)極(ji)(ji)(ji)振打(da)系統的(de)(de)(de)振打(da)，使(shi)沉(chen)積(ji)在陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)振落(luo)，進人集灰(hui)斗 通過(guo)排灰(hui)裝置放(fang)出，回收有物料，被(bei))凈化的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作(zuo)原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)工作原理是利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用(yong)下與氣流(liu)分離(li)。負極由不(bu)同(tong)斷面形狀的(de)金屬(shu)導(dao)線制成(cheng)(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同(tong)幾何形狀的(de)金屬(shu)板制成(cheng)(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質(zhi)、設備(bei)構造和(he)煙氣流(liu)速(su)等三(san)個因素的(de)影響。粉(fen)塵(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標(biao)，它對除(chu)塵(chen)(chen)效率有直接的(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難(nan)以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重返氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)出，在塵(chen)(chen)層之(zhi)間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產(chan)生局部(bu)擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)(cheng)除(chu)塵(chen)(chen)效率下降。

電除塵(chen)器的(de)基本原(yuan)理(li)是利(li)用電力捕集(ji)煙氣中的(de)粉(fen)塵(chen)，主(zhu)要包括以下四個(ge)相互有關的(de)物理(li)過程: (1) 氣體的(de)電離。(2) 粉(fen)塵(chen)的(de)荷電。(3) 荷電粉(fen)塵(chen)向電極移動。(4) 荷電粉(fen)塵(chen)的(de)捕集(ji)。
