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)器是以靜電(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)工作(zuo)上(shang)(shang)要是依(yi)靠電(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)(chen)淀兩個系統來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的(de)(de)(de)(de)調整(zheng)后，使(shi)(shi)氣(qi)(qi)流(liu)能較均勻地進(jin)(jin)人(ren)電(dian)(dian)場。在(zai)(zai)橫斷(duan)面擴大的(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)流(liu)速(su)度迅速(su)降(jiang)低，其中有些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)粒便失去速(su)度而沉(chen)(chen)降(jiang)下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)暈極(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)附近產生電(dian)(dian)暈現象(xiang)，使(shi)(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在(zai)(zai)大量(liang)的(de)(de)(de)(de)電(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這些(xie)電(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合起(qi)來(lai)，使(shi)(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下趨向本設(she)備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備(bei)采用負(fu)高(gao)壓(ya)制(zhi))和(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)(chu)電(dian)(dian)子(zi)分別沉(chen)(chen)積在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)，通(tong)過設(she)備(bei)陰(yin)陽極(ji)(ji)(ji)振打系統的(de)(de)(de)(de)振打，使(shi)(shi)沉(chen)(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落(luo)，進(jin)(jin)人(ren)集(ji)灰斗 通(tong)過排灰裝置放出(chu)(chu)，回收有物料，被)凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)(qi)的(de)(de)(de)(de)工(gong)作原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)流分離。負(fu)極(ji)(ji)由不(bu)(bu)同斷(duan)面(mian)形(xing)(xing)狀的(de)(de)(de)(de)金屬導線(xian)制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)(bu)同幾何形(xing)(xing)狀的(de)(de)(de)(de)金屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)(qi)的(de)(de)(de)(de)性能受粉(fen)(fen)塵(chen)性質(zhi)、設備(bei)構造和(he)(he)煙(yan)氣(qi)流速(su)等三個(ge)因素的(de)(de)(de)(de)影(ying)(ying)響。粉(fen)(fen)塵(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指(zhi)標，它(ta)對除塵(chen)效率有直接的(de)(de)(de)(de)影(ying)(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒難以保(bao)持(chi)在集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到(dao)達集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在塵(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局(ju)部擊(ji)穿和(he)(he)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造成(cheng)除塵(chen)效率下降(jiang)。

電(dian)除塵(chen)器的基本原理是利用電(dian)力捕(bu)集煙氣中的粉(fen)(fen)塵(chen)，主(zhu)要包括以下四(si)個相互(hu)有關的物理過程: (1) 氣體的電(dian)離。(2) 粉(fen)(fen)塵(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)(fen)塵(chen)的捕(bu)集。
