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)電(dian)(dian)(dian)(dian)除塵(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來收捕廢氣(qi)(qi)中的(de)(de)粉(fen)(fen)塵(chen)，它的(de)(de)凈(jing)(jing)化(hua)工作上要是依(yi)靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)(he)沉淀兩(liang)個(ge)系統來完成的(de)(de)，當含(han)(han)塵(chen)氣(qi)(qi)體(ti)進(jin)(jin)人氣(qi)(qi)刺叭(ba)時，含(han)(han)塵(chen)氣(qi)(qi)體(ti)受(shou)到氣(qi)(qi)流分布板(ban)(ban)以及折流板(ban)(ban)的(de)(de)調整后，使氣(qi)(qi)流能較均勻地進(jin)(jin)人電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大(da)的(de)(de)作用下，氣(qi)(qi)流速(su)度迅速(su)降低，其中有些較重的(de)(de)塵(chen)粒(li)便失去(qu)速(su)度而沉降下來。進(jin)(jin)人電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)含(han)(han)塵(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人高壓直(zhi)流電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)中存在(zai)(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)與(yu)進(jin)(jin)人電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉(fen)(fen)塵(chen)結合起來，使塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用下趨向本(ben)設(she)備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)備采用負高壓制)和(he)(he)陰(yin)(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積(ji)在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設(she)備陰(yin)(yin)陽(yang)極(ji)(ji)(ji)振打系統的(de)(de)振打，使沉積(ji)在(zai)(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉(fen)(fen)塵(chen)振落，進(jin)(jin)人集(ji)灰斗 通過排灰裝置放(fang)出(chu)，回(hui)收有物料，被)凈(jing)(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工(gong)作(zuo)原理(li)

靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)工(gong)作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣(qi)(qi)流分離。負(fu)極(ji)(ji)由不(bu)(bu)同斷面形狀的(de)金屬導線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不(bu)(bu)同幾何形狀的(de)金屬板制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)性能受粉塵(chen)(chen)(chen)性質、設(she)備構造和煙氣(qi)(qi)流速(su)等三(san)個因素(su)的(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對(dui)除塵(chen)(chen)(chen)效率(lv)有直接的(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)(li)難以保(bao)持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使(shi)其重返氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒(li)(li)電(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易放(fang)出(chu)，在塵(chen)(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生(sheng)局(ju)部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況都會造成(cheng)除塵(chen)(chen)(chen)效率(lv)下降。

電除塵器的(de)(de)(de)基本原理是利用(yong)電力捕集煙(yan)氣中的(de)(de)(de)粉(fen)塵，主要(yao)包括以下四個相互有(you)關(guan)的(de)(de)(de)物(wu)理過程: (1) 氣體的(de)(de)(de)電離(li)。(2) 粉(fen)塵的(de)(de)(de)荷(he)電。(3) 荷(he)電粉(fen)塵向電極(ji)移動。(4) 荷(he)電粉(fen)塵的(de)(de)(de)捕集。
