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(shi)靜電(dian)(dian)除(chu)塵(chen)(chen)器是(shi)以靜電(dian)(dian)凈化法(fa)來收(shou)捕廢氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈化工(gong)作上(shang)要是(shi)依靠電(dian)(dian)暈(yun)(yun)極(ji)和沉(chen)(chen)(chen)淀兩個系統來完成的(de)(de)，當(dang)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)(jin)人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流分布板以及折流板的(de)(de)調整后(hou)，使氣(qi)(qi)流能較(jiao)均勻地進(jin)(jin)(jin)人(ren)電(dian)(dian)場。在橫斷面擴大(da)的(de)(de)作用下(xia)，氣(qi)(qi)流速度(du)迅速降低，其(qi)中有些較(jiao)重的(de)(de)塵(chen)(chen)粒(li)便失去速度(du)而沉(chen)(chen)(chen)降下(xia)來。進(jin)(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)(yun)極(ji)通人(ren)高壓直(zhi)流電(dian)(dian)，則(ze)在電(dian)(dian)暈(yun)(yun)極(ji)附近(jin)產生電(dian)(dian)暈(yun)(yun)現象(xiang)，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后(hou)的(de)(de)氣(qi)(qi)體(ti)(ti)中存在大(da)量的(de)(de)電(dian)(dian)子(zi)和離(li)(li)子(zi)，這(zhe)些電(dian)(dian)子(zi)和離(li)(li)子(zi)與進(jin)(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)粉(fen)塵(chen)(chen)結(jie)合(he)起來，使塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)場力的(de)(de)作用下(xia)趨向本設(she)(she)備(bei)陽(yang)極(ji)(正極(ji)、本設(she)(she)備(bei)采用負高壓制)和陰極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)子(zi)分別沉(chen)(chen)(chen)積(ji)在相(xiang)應的(de)(de)電(dian)(dian)極(ji)上(shang)，通過設(she)(she)備(bei)陰陽(yang)極(ji)振打(da)系統的(de)(de)振打(da)，使沉(chen)(chen)(chen)積(ji)在陰陽(yang)電(dian)(dian)極(ji)上(shang)的(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)(jin)(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝(zhuang)置放(fang)出，回收(shou)有物料，被)凈化的(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理(li)是利用(yong)高(gao)壓電(dian)(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用(yong)下與氣(qi)流(liu)分離。負極(ji)由(you)不同斷面形(xing)狀的(de)(de)(de)金屬(shu)導(dao)線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形(xing)狀的(de)(de)(de)金屬(shu)板制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)性(xing)能(neng)受粉塵(chen)(chen)性(xing)質、設備(bei)構(gou)造(zao)和煙氣(qi)流(liu)速等三個因素的(de)(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是評價(jia)導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它(ta)對除塵(chen)(chen)效(xiao)率(lv)有直(zhi)接的(de)(de)(de)影響(xiang)。比電(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)粒難以保(bao)持(chi)在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)流(liu)。比電(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會(hui)產(chan)生局部擊穿和放(fang)電(dian)(dian)(dian)現象。這(zhe)些情(qing)況(kuang)都(dou)會(hui)造(zao)成(cheng)除塵(chen)(chen)效(xiao)率(lv)下降。

電除塵(chen)器(qi)的基本原(yuan)理是利用電力捕集(ji)煙氣(qi)中的粉塵(chen)，主要(yao)包括以下四個相(xiang)互有關的物理過程: (1) 氣(qi)體的電離。(2) 粉塵(chen)的荷電。(3) 荷電粉塵(chen)向(xiang)電極移動。(4) 荷電粉塵(chen)的捕集(ji)。
