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(chu)塵器是以靜電(dian)(dian)凈化(hua)法(fa)來收捕廢(fei)氣(qi)(qi)(qi)中(zhong)的(de)粉(fen)塵，它的(de)凈化(hua)工(gong)作上(shang)要是依靠電(dian)(dian)暈(yun)極(ji)和(he)(he)(he)沉(chen)(chen)淀(dian)兩個系統來完成(cheng)的(de)，當含塵氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人氣(qi)(qi)(qi)刺叭時，含塵氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分(fen)布板以及折(zhe)流板的(de)調(diao)整后(hou)，使(shi)(shi)(shi)氣(qi)(qi)(qi)流能較均勻地進(jin)(jin)人電(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴(kuo)大(da)的(de)作用下(xia)(xia)，氣(qi)(qi)(qi)流速度迅速降(jiang)(jiang)低(di)，其中(zhong)有些(xie)較重的(de)塵粒(li)便失(shi)去速度而沉(chen)(chen)降(jiang)(jiang)下(xia)(xia)來。進(jin)(jin)人電(dian)(dian)場(chang)的(de)含塵氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)極(ji)通人高壓直流電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈(yun)極(ji)附(fu)近產生電(dian)(dian)暈(yun)現(xian)象，使(shi)(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后(hou)的(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)大(da)量(liang)的(de)電(dian)(dian)子(zi)(zi)和(he)(he)(he)離子(zi)(zi)，這些(xie)電(dian)(dian)子(zi)(zi)和(he)(he)(he)離子(zi)(zi)與(yu)進(jin)(jin)人電(dian)(dian)場(chang)的(de)粉(fen)塵結(jie)合起來，使(shi)(shi)(shi)塵粒(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵粒(li)在(zai)(zai)電(dian)(dian)場(chang)力的(de)作用下(xia)(xia)趨向本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用負(fu)高壓制)和(he)(he)(he)陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)子(zi)(zi)分(fen)別沉(chen)(chen)積(ji)在(zai)(zai)相(xiang)應的(de)電(dian)(dian)極(ji)上(shang)，通過(guo)設備(bei)陰陽極(ji)振打系統的(de)振打，使(shi)(shi)(shi)沉(chen)(chen)積(ji)在(zai)(zai)陰陽電(dian)(dian)極(ji)上(shang)的(de)粉(fen)塵振落，進(jin)(jin)人集(ji)灰(hui)斗 通過(guo)排灰(hui)裝置放出，回(hui)收有物料(liao)，被(bei))凈化(hua)的(de)氣(qi)(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的工(gong)作(zuo)(zuo)原(yuan)理是利用高壓電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作(zuo)(zuo)用下與氣(qi)(qi)流分離(li)。負極由不(bu)同斷面(mian)形(xing)狀的金屬導線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形(xing)狀的金屬板制(zhi)成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設備構造(zao)和煙氣(qi)(qi)流速等(deng)三個因素的影響。粉(fen)塵(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性(xing)(xing)的指標，它對除(chu)塵(chen)(chen)(chen)效率有直接的影響。比電(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)粒(li)難(nan)以保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其重返氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)層之(zhi)間(jian)形(xing)成電(dian)(dian)(dian)(dian)壓梯度會產生局部(bu)擊穿和放電(dian)(dian)(dian)(dian)現象(xiang)。這些(xie)情況(kuang)都(dou)會造(zao)成除(chu)塵(chen)(chen)(chen)效率下降(jiang)。

電(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)基本原理是利用電(dian)(dian)力捕集煙(yan)氣(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)，主(zhu)要包括(kuo)以(yi)下(xia)四個相互有關(guan)的(de)(de)(de)(de)物理過程: (1) 氣(qi)體(ti)的(de)(de)(de)(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)(de)(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵(chen)(chen)的(de)(de)(de)(de)捕集。
