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。

臥式靜電(dian)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)凈化(hua)法來收捕廢氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈化(hua)工作(zuo)上要是依靠電(dian)(dian)暈極(ji)(ji)(ji)(ji)和(he)(he)沉淀兩(liang)個(ge)系統(tong)來完(wan)成的(de)(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)調整后，使氣(qi)(qi)流(liu)能較均勻地進(jin)人(ren)電(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)速(su)度(du)迅速(su)降(jiang)低，其中有些較重的(de)(de)塵(chen)(chen)(chen)粒(li)便失(shi)去(qu)速(su)度(du)而沉降(jiang)下來。進(jin)人(ren)電(dian)(dian)場的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈極(ji)(ji)(ji)(ji)通(tong)人(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈極(ji)(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)暈現(xian)象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)(ti)中存(cun)在(zai)(zai)大(da)量的(de)(de)電(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)，這些電(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)與進(jin)人(ren)電(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)結(jie)合起(qi)來，使塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)場力(li)的(de)(de)作(zuo)用(yong)下趨(qu)向本(ben)(ben)設(she)備(bei)(bei)陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)(ben)設(she)備(bei)(bei)采用(yong)負(fu)高(gao)壓(ya)制)和(he)(he)陰極(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)子(zi)(zi)分(fen)別沉積(ji)在(zai)(zai)相(xiang)應(ying)的(de)(de)電(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)過(guo)設(she)備(bei)(bei)陰陽極(ji)(ji)(ji)(ji)振打系統(tong)的(de)(de)振打，使沉積(ji)在(zai)(zai)陰陽電(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)振落(luo)，進(jin)人(ren)集(ji)灰斗 通(tong)過(guo)排灰裝置放出，回(hui)收有物料，被)凈化(hua)的(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)。

工(gong)作原(yuan)理

靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)的(de)(de)工作原(yuan)理是利(li)用(yong)高壓(ya)電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)流中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用(yong)下與氣(qi)流分離(li)。負極(ji)(ji)由不同斷(duan)面形(xing)狀的(de)(de)金屬(shu)導線(xian)制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不同幾何形(xing)狀的(de)(de)金屬(shu)板制成(cheng)，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)的(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設備(bei)構(gou)造(zao)和煙氣(qi)流速等三個因(yin)素(su)的(de)(de)影(ying)(ying)響(xiang)。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)(chen)效率有直接(jie)的(de)(de)影(ying)(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持(chi)在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使(shi)其重返氣(qi)流。比電(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放出，在(zai)塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生局部擊穿和放電(dian)(dian)(dian)(dian)現象(xiang)。這些情況都(dou)會造(zao)成(cheng)除塵(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器的(de)(de)基本原理(li)是利(li)用(yong)電(dian)(dian)力捕集(ji)煙氣中的(de)(de)粉(fen)(fen)(fen)塵(chen)，主要(yao)包括以下四個相互有關的(de)(de)物理(li)過程: (1) 氣體(ti)的(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)(fen)塵(chen)的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)(fen)塵(chen)向電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉(fen)(fen)(fen)塵(chen)的(de)(de)捕集(ji)。
