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)除塵(chen)(chen)器是以靜(jing)電(dian)(dian)凈(jing)(jing)化(hua)法來(lai)(lai)收捕(bu)廢氣(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)(jing)化(hua)工作(zuo)(zuo)上(shang)要是依(yi)靠電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)和沉淀兩(liang)個系統來(lai)(lai)完成的(de)(de)(de)，當含塵(chen)(chen)氣(qi)體(ti)進(jin)人氣(qi)刺叭時，含塵(chen)(chen)氣(qi)體(ti)受到(dao)氣(qi)流(liu)分布板以及折(zhe)流(liu)板的(de)(de)(de)調整(zheng)后(hou)(hou)，使氣(qi)流(liu)能較(jiao)均勻(yun)地進(jin)人電(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴大(da)的(de)(de)(de)作(zuo)(zuo)用(yong)下，氣(qi)流(liu)速(su)度(du)迅速(su)降(jiang)低，其(qi)中(zhong)有些較(jiao)重的(de)(de)(de)塵(chen)(chen)粒便(bian)失(shi)去速(su)度(du)而沉降(jiang)下來(lai)(lai)。進(jin)人電(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)通人高壓直流(liu)電(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)暈(yun)(yun)現象，使氣(qi)體(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后(hou)(hou)的(de)(de)(de)氣(qi)體(ti)中(zhong)存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)子和離(li)子，這些電(dian)(dian)子和離(li)子與(yu)進(jin)人電(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合(he)起來(lai)(lai)，使塵(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)(zuo)用(yong)下趨(qu)向本設備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)采用(yong)負(fu)高壓制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)子分別沉積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振打系統的(de)(de)(de)振打，使沉積在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人集灰(hui)斗 通過排(pai)灰(hui)裝置(zhi)放出，回收有物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)體(ti)排(pai)入(ru)大(da)氣(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的工作原理(li)是(shi)(shi)利(li)用高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中(zhong)的粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流分離。負(fu)極(ji)由不(bu)同斷面形(xing)狀(zhuang)的金(jin)屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾(ji)何形(xing)狀(zhuang)的金(jin)屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)(qi)流速等三個因素(su)的影(ying)響。粉(fen)塵(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)阻是(shi)(shi)評價導電(dian)(dian)(dian)(dian)性(xing)的指標，它對(dui)除塵(chen)(chen)(chen)效(xiao)率有直接的影(ying)響。比電(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)粒難(nan)以保(bao)持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其(qi)重返(fan)氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部(bu)擊穿和放電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造(zao)成(cheng)除塵(chen)(chen)(chen)效(xiao)率下降(jiang)。

電除塵器(qi)的(de)基(ji)本原理是利(li)用(yong)電力捕(bu)集(ji)煙氣(qi)中(zhong)的(de)粉塵，主要包括以下四(si)個相互有關的(de)物(wu)理過(guo)程: (1) 氣(qi)體的(de)電離。(2) 粉塵的(de)荷(he)電。(3) 荷(he)電粉塵向電極移動。(4) 荷(he)電粉塵的(de)捕(bu)集(ji)。
