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)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)是以靜(jing)(jing)電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)(lai)(lai)收捕(bu)廢氣(qi)(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它(ta)的(de)(de)(de)凈化(hua)工作(zuo)上要(yao)是依(yi)靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)(he)(he)沉(chen)(chen)淀兩個系統來(lai)(lai)(lai)完成的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)進人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)受(shou)到氣(qi)(qi)流分(fen)布板(ban)以及折流板(ban)的(de)(de)(de)調整(zheng)后，使(shi)氣(qi)(qi)流能較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)的(de)(de)(de)作(zuo)用下，氣(qi)(qi)流速(su)(su)度迅速(su)(su)降低，其中(zhong)有(you)些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速(su)(su)度而(er)沉(chen)(chen)降下來(lai)(lai)(lai)。進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)(he)(he)離(li)子，這些(xie)電(dian)(dian)(dian)(dian)子和(he)(he)(he)離(li)子與進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結(jie)合(he)起來(lai)(lai)(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用下趨(qu)向本設(she)(she)備陽極(ji)(正極(ji)、本設(she)(she)備采用負(fu)高壓(ya)制)和(he)(he)(he)陰(yin)(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)子分(fen)別沉(chen)(chen)積在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通過(guo)設(she)(she)備陰(yin)(yin)陽極(ji)振(zhen)打(da)系統的(de)(de)(de)振(zhen)打(da)，使(shi)沉(chen)(chen)積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)集灰(hui)斗 通過(guo)排灰(hui)裝置放(fang)出(chu)，回收有(you)物料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排入大(da)氣(qi)(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)工作原理(li)是利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)流(liu)分離(li)。負極(ji)(ji)由不同(tong)斷面形(xing)(xing)狀的(de)(de)(de)金(jin)(jin)屬(shu)導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何形(xing)(xing)狀的(de)(de)(de)金(jin)(jin)屬(shu)板制成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和煙氣(qi)流(liu)速等三個因素的(de)(de)(de)影響。粉塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)效率有直(zhi)接的(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒難以(yi)保持(chi)在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其重(zhong)返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高(gao)，到(dao)達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在塵(chen)(chen)層(ceng)之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產(chan)生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些(xie)情(qing)況都會造成(cheng)除(chu)塵(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)器的基本原(yuan)理是利用(yong)電(dian)(dian)(dian)力捕集煙氣中的粉塵(chen)，主要包括以下四個相互有關(guan)的物(wu)理過程(cheng): (1) 氣體的電(dian)(dian)(dian)離。(2) 粉塵(chen)的荷(he)(he)電(dian)(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)極移動。(4) 荷(he)(he)電(dian)(dian)(dian)粉塵(chen)的捕集。
