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)除塵(chen)(chen)(chen)(chen)器(qi)是(shi)以靜(jing)電(dian)凈化法(fa)來(lai)收捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)，它的(de)凈化工作上要是(shi)依靠電(dian)暈極(ji)(ji)(ji)(ji)(ji)和沉(chen)淀兩個系統來(lai)完成的(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受(shou)到(dao)氣(qi)(qi)(qi)(qi)(qi)流(liu)分(fen)布(bu)板以及折流(liu)板的(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)能(neng)較(jiao)(jiao)均勻地進(jin)(jin)人(ren)(ren)電(dian)場。在橫斷面擴(kuo)大(da)(da)的(de)作用下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速(su)度(du)(du)迅速(su)降低，其(qi)中(zhong)有些較(jiao)(jiao)重(zhong)的(de)塵(chen)(chen)(chen)(chen)粒便(bian)失去(qu)速(su)度(du)(du)而沉(chen)降下來(lai)。進(jin)(jin)人(ren)(ren)電(dian)場的(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)暈極(ji)(ji)(ji)(ji)(ji)通人(ren)(ren)高壓直流(liu)電(dian)，則在電(dian)暈極(ji)(ji)(ji)(ji)(ji)附(fu)近(jin)產生電(dian)暈現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)離(li)，電(dian)離(li)后(hou)的(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中(zhong)存在大(da)(da)量(liang)的(de)電(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)(jin)人(ren)(ren)電(dian)場的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒帶電(dian)，帶電(dian)塵(chen)(chen)(chen)(chen)粒在電(dian)場力的(de)作用下趨向本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設(she)備(bei)采用負(fu)(fu)高壓制)和陰(yin)極(ji)(ji)(ji)(ji)(ji)(負(fu)(fu)極(ji)(ji)(ji)(ji)(ji)) ， 釋放(fang)(fang)出電(dian)子(zi)(zi)分(fen)別沉(chen)積(ji)在相應的(de)電(dian)極(ji)(ji)(ji)(ji)(ji)上，通過設(she)備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)(ji)(ji)振打(da)系統的(de)振打(da)，使(shi)沉(chen)積(ji)在陰(yin)陽(yang)電(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)振落(luo)，進(jin)(jin)人(ren)(ren)集灰斗 通過排灰裝置(zhi)放(fang)(fang)出，回收有物料，被(bei))凈化的(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排入大(da)(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)的(de)(de)工(gong)作原理是利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)分(fen)離(li)。負極(ji)(ji)由不(bu)同斷面形狀的(de)(de)金(jin)屬導線制(zhi)(zhi)成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何形狀的(de)(de)金(jin)屬板制(zhi)(zhi)成，叫集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)的(de)(de)性能受粉(fen)塵(chen)性質、設備構造和煙(yan)氣(qi)流(liu)速等三(san)個因素的(de)(de)影響。粉(fen)塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指(zhi)標，它對除(chu)(chu)塵(chen)效率有直接(jie)的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)粒難以(yi)保(bao)持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)出，在塵(chen)層之間形成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成除(chu)(chu)塵(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)(chen)器的(de)基本原(yuan)理是(shi)利用電(dian)(dian)(dian)力捕集煙(yan)氣中的(de)粉(fen)塵(chen)(chen)，主要包括以下四(si)個相互有關的(de)物理過程(cheng): (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向(xiang)電(dian)(dian)(dian)極移(yi)動(dong)。(4) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集。
