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)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收捕廢氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)化工(gong)作上要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)(he)沉(chen)淀兩(liang)個系(xi)統來完成(cheng)的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分(fen)布板以及折流板的(de)(de)調整(zheng)后，使(shi)(shi)氣(qi)(qi)流能(neng)較均勻(yun)地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大(da)的(de)(de)作用(yong)下(xia)，氣(qi)(qi)流速度迅速降(jiang)低，其中有(you)些(xie)較重的(de)(de)塵(chen)(chen)粒(li)便失(shi)去速度而沉(chen)降(jiang)下(xia)來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)中存在(zai)大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離(li)子，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離(li)子與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下(xia)趨向本(ben)(ben)設備陽(yang)極(ji)(正極(ji)、本(ben)(ben)設備采用(yong)負高壓制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子分(fen)別沉(chen)積(ji)在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設備陰陽(yang)極(ji)振打(da)系(xi)統的(de)(de)振打(da)，使(shi)(shi)沉(chen)積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)粉塵(chen)(chen)振落，進(jin)人(ren)(ren)集灰斗 通過排(pai)灰裝(zhuang)置放(fang)出，回收有(you)物料，被)凈(jing)化的(de)(de)氣(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)工(gong)作(zuo)原理(li)是(shi)利(li)用(yong)(yong)高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)離(li)，氣(qi)流中(zhong)的(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作(zuo)用(yong)(yong)下(xia)與氣(qi)流分離(li)。負極(ji)(ji)(ji)由不(bu)(bu)同斷面形(xing)狀的(de)金(jin)屬(shu)導線(xian)制(zhi)成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不(bu)(bu)同幾(ji)何(he)形(xing)狀的(de)金(jin)屬(shu)板(ban)制(zhi)成，叫(jiao)集塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設備構造(zao)和(he)煙氣(qi)流速等三個因素的(de)影響。粉(fen)塵(chen)的(de)比電(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)性(xing)的(de)指標，它(ta)對(dui)除(chu)塵(chen)效率(lv)有直(zhi)接的(de)影響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)粒(li)難以保持在集塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致使(shi)其(qi)重返氣(qi)流。比電(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在塵(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)壓梯(ti)度會產(chan)生(sheng)局部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情(qing)況都會造(zao)成除(chu)塵(chen)效率(lv)下(xia)降。

電(dian)(dian)除塵(chen)器的基(ji)本原理是利用電(dian)(dian)力捕(bu)集煙氣(qi)中的粉塵(chen)，主要包括以下四個相互有關的物理過(guo)程: (1) 氣(qi)體(ti)的電(dian)(dian)離。(2) 粉塵(chen)的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵(chen)的捕(bu)集。
