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)(dian)除(chu)塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈(jing)(jing)化(hua)工作(zuo)上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩(liang)個系統(tong)來(lai)完成(cheng)的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體進(jin)人氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體受到(dao)氣(qi)(qi)(qi)流分(fen)布(bu)板以及折流板的(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)流能(neng)較均勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面(mian)擴(kuo)大的(de)(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)流速度迅(xun)速降低，其中(zhong)有些(xie)較重的(de)(de)塵(chen)(chen)(chen)粒(li)便失去(qu)速度而(er)沉降下來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高(gao)壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)體中(zhong)存在大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)作(zuo)用(yong)下趨向本(ben)設(she)備(bei)陽(yang)(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)備(bei)采(cai)用(yong)負高(gao)壓制(zhi))和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉積在相(xiang)應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設(she)備(bei)陰陽(yang)(yang)極(ji)(ji)(ji)振打系統(tong)的(de)(de)振打，使(shi)(shi)沉積在陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)人集灰斗 通過(guo)排灰裝(zhuang)置放出，回收有物料(liao)，被)凈(jing)(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)工(gong)作原理是利用高壓電(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場作用下(xia)與氣(qi)流分離。負極(ji)(ji)(ji)(ji)由不同斷面形狀的(de)(de)金屬導線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)由不同幾何形狀的(de)(de)金屬板制(zhi)成，叫(jiao)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造和煙氣(qi)流速等三(san)個因素(su)的(de)(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)效率有(you)直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)(chen)(chen)粒(li)難(nan)以保(bao)持在(zai)(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)，致使其重返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易放出，在(zai)(zai)塵(chen)(chen)(chen)(chen)(chen)層之(zhi)間(jian)形成電(dian)(dian)(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)除塵(chen)(chen)器(qi)的(de)(de)基本原理(li)(li)是(shi)利用電(dian)力捕集(ji)煙氣中的(de)(de)粉(fen)塵(chen)(chen)，主要包括以下四個相互有關的(de)(de)物(wu)理(li)(li)過程: (1) 氣體(ti)的(de)(de)電(dian)離(li)。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集(ji)。
