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(wo)式靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)(lai)收(shou)捕(bu)廢氣(qi)(qi)中的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈(jing)化(hua)工(gong)作(zuo)(zuo)上(shang)(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)(he)沉淀(dian)兩個系(xi)統(tong)來(lai)(lai)完成的(de)(de)(de)，當含(han)(han)塵(chen)氣(qi)(qi)體(ti)進人(ren)氣(qi)(qi)刺叭時，含(han)(han)塵(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分(fen)布板以(yi)及折(zhe)流板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)流能(neng)較(jiao)均勻(yun)地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷面擴(kuo)大(da)的(de)(de)(de)作(zuo)(zuo)用(yong)下(xia)，氣(qi)(qi)流速(su)度(du)迅(xun)速(su)降低，其中有些較(jiao)重的(de)(de)(de)塵(chen)粒便失去(qu)速(su)度(du)而沉降下(xia)來(lai)(lai)。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)(han)塵(chen)氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)體(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)與(yu)進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)結合起來(lai)(lai)，使(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)(zuo)用(yong)下(xia)趨向本設(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備采(cai)用(yong)負高(gao)壓制(zhi))和(he)(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，通(tong)過設(she)備陰(yin)陽(yang)極(ji)(ji)振(zhen)打系(xi)統(tong)的(de)(de)(de)振(zhen)打，使(shi)沉積在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)的(de)(de)(de)粉塵(chen)振(zhen)落，進人(ren)集灰(hui)斗(dou) 通(tong)過排灰(hui)裝置放(fang)出(chu)，回收(shou)有物料，被(bei))凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)粉(fen)(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流(liu)分離。負極(ji)(ji)(ji)由不同(tong)斷(duan)面形(xing)狀的(de)(de)金(jin)屬導(dao)線制(zhi)成(cheng)(cheng)，叫(jiao)(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同(tong)幾何形(xing)狀的(de)(de)金(jin)屬板制(zhi)成(cheng)(cheng)，叫(jiao)(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能受粉(fen)(fen)塵(chen)(chen)性質、設(she)備構(gou)造(zao)和(he)煙氣(qi)(qi)流(liu)速等三個(ge)因素(su)的(de)(de)影(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)效率有(you)直接(jie)的(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)低(di)，塵(chen)(chen)粒(li)難以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致使其重(zhong)返(fan)氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)層之間(jian)形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓梯度會產(chan)生局部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造(zao)成(cheng)(cheng)除(chu)塵(chen)(chen)效率下降(jiang)。

電(dian)除塵(chen)器的(de)(de)基本原理是利用電(dian)力捕(bu)集(ji)(ji)煙氣中的(de)(de)粉(fen)(fen)塵(chen)，主要包括以下四個相互有(you)關的(de)(de)物理過(guo)程: (1) 氣體(ti)的(de)(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)(fen)塵(chen)的(de)(de)捕(bu)集(ji)(ji)。
