XWD型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)(dian)除(chu)塵(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收捕廢氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈(jing)化工(gong)作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極和(he)(he)沉淀兩個系統來完成的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)流(liu)(liu)(liu)分(fen)(fen)布(bu)板以及折流(liu)(liu)(liu)板的(de)(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)(liu)能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)流(liu)(liu)(liu)速(su)(su)度迅速(su)(su)降低(di)，其中有些較重(zhong)的(de)(de)塵(chen)(chen)(chen)粒便失(shi)去(qu)速(su)(su)度而(er)沉降下來。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極通人(ren)高壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)后的(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離(li)(li)(li)子，這些電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離(li)(li)(li)子與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)(chen)結合起(qi)來，使(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下趨(qu)向本設備(bei)陽極(正(zheng)極、本設備(bei)采用(yong)負高壓制)和(he)(he)陰(yin)(yin)極(負極) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子分(fen)(fen)別沉積在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)極上(shang)，通過設備(bei)陰(yin)(yin)陽極振(zhen)(zhen)打系統的(de)(de)振(zhen)(zhen)打，使(shi)沉積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)(dian)極上(shang)的(de)(de)粉塵(chen)(chen)(chen)振(zhen)(zhen)落(luo)，進(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝置放(fang)出，回收有物料，被)凈(jing)化的(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工作原理是(shi)(shi)利用(yong)高(gao)壓(ya)電(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)離，氣流中(zhong)的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下與氣流分離。負(fu)極(ji)由(you)(you)不(bu)同(tong)斷面形狀的(de)(de)金(jin)屬導(dao)線(xian)制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)(you)不(bu)同(tong)幾何形狀的(de)(de)金(jin)屬板制(zhi)成(cheng)(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性能(neng)受粉塵(chen)(chen)(chen)性質、設備構造和煙氣流速等三個因(yin)素的(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是(shi)(shi)評價(jia)導(dao)電(dian)(dian)(dian)性的(de)(de)指(zhi)標(biao)，它(ta)對(dui)除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)影響(xiang)。比電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保(bao)持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致(zhi)使其(qi)重返氣流。比電(dian)(dian)(dian)阻過(guo)高(gao)，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)層之(zhi)間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)梯度會(hui)產生局部擊穿和放電(dian)(dian)(dian)現象。這些情況(kuang)都會(hui)造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)效率下降。

電除(chu)塵(chen)器的(de)(de)基本原理是利(li)用電力(li)捕(bu)集(ji)煙氣中的(de)(de)粉(fen)塵(chen)，主(zhu)要(yao)包括以下四個相互有關的(de)(de)物理過程: (1) 氣體的(de)(de)電離。(2) 粉(fen)塵(chen)的(de)(de)荷(he)(he)電。(3) 荷(he)(he)電粉(fen)塵(chen)向電極(ji)移動。(4) 荷(he)(he)電粉(fen)塵(chen)的(de)(de)捕(bu)集(ji)。
