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(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除塵器是以靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵，它的(de)(de)(de)凈(jing)化工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)(he)沉(chen)(chen)淀(dian)兩個系(xi)統來(lai)完成的(de)(de)(de)，當含塵氣(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含塵氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)(de)調整后，使氣(qi)(qi)流(liu)能較均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面(mian)擴(kuo)大(da)的(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)流(liu)速(su)度(du)(du)迅速(su)降低，其中(zhong)有(you)些較重的(de)(de)(de)塵粒(li)便失去(qu)速(su)度(du)(du)而沉(chen)(chen)降下(xia)來(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)(ti)(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)(de)氣(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)(li)(li)子(zi)(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵結合起(qi)來(lai)，使塵粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用下(xia)趨向(xiang)本設備陽極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本設備采用負(fu)高(gao)壓(ya)制)和(he)(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉(chen)(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設備陰(yin)陽極(ji)(ji)(ji)振(zhen)打(da)系(xi)統的(de)(de)(de)振(zhen)打(da)，使沉(chen)(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵振(zhen)落，進(jin)人(ren)(ren)集灰(hui)斗 通過排(pai)灰(hui)裝置放出，回(hui)收有(you)物料，被(bei))凈(jing)化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排(pai)入大(da)氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)工作(zuo)(zuo)原理是(shi)利用高(gao)(gao)壓(ya)電(dian)(dian)場(chang)使(shi)煙(yan)氣發(fa)生(sheng)(sheng)電(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作(zuo)(zuo)用下與氣流(liu)分(fen)離。負極(ji)(ji)(ji)由不同斷(duan)面形(xing)狀的(de)金(jin)屬(shu)導線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同幾何形(xing)狀的(de)金(jin)屬(shu)板制(zhi)成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)性能受粉塵(chen)(chen)(chen)(chen)性質、設備(bei)構造(zao)和煙(yan)氣流(liu)速等三個因素的(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)性的(de)指標，它對(dui)除塵(chen)(chen)(chen)(chen)效(xiao)率(lv)有直接(jie)的(de)影(ying)響。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)上，致使(shi)其重返氣流(liu)。比電(dian)(dian)阻(zu)過高(gao)(gao)，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)壓(ya)梯(ti)度會產生(sheng)(sheng)局部擊穿和放電(dian)(dian)現(xian)象。這些(xie)情況(kuang)都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)(dian)除塵(chen)(chen)器的(de)基本原理(li)(li)是利用電(dian)(dian)力捕集煙氣中的(de)粉(fen)(fen)(fen)塵(chen)(chen)，主要包括以下(xia)四(si)個相互有(you)關的(de)物理(li)(li)過(guo)程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉(fen)(fen)(fen)塵(chen)(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)(fen)(fen)塵(chen)(chen)向(xiang)電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)(fen)(fen)塵(chen)(chen)的(de)捕集。
