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)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以(yi)靜(jing)(jing)電(dian)(dian)(dian)(dian)凈化(hua)法(fa)來(lai)收捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)(de)凈化(hua)工(gong)作上(shang)要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉(chen)淀兩個系統來(lai)完成的(de)(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)(qi)(qi)刺(ci)叭時(shi)，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流分布(bu)板(ban)以(yi)及折(zhe)流板(ban)的(de)(de)(de)(de)(de)(de)(de)調整后(hou)，使氣(qi)(qi)(qi)(qi)(qi)流能(neng)較(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷面擴大的(de)(de)(de)(de)(de)(de)(de)作用(yong)(yong)下，氣(qi)(qi)(qi)(qi)(qi)流速度迅速降低，其中有(you)(you)些較(jiao)重的(de)(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失去速度而(er)沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)人(ren)高壓(ya)直(zhi)流電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產(chan)生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)中存在(zai)(zai)大量的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)離(li)(li)子，這(zhe)些電(dian)(dian)(dian)(dian)子和(he)離(li)(li)子與進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)(de)(de)作用(yong)(yong)下趨向本(ben)設(she)備(bei)(bei)陽(yang)極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本(ben)設(she)備(bei)(bei)采用(yong)(yong)負高壓(ya)制)和(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在(zai)(zai)相應的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過設(she)備(bei)(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振打(da)系統的(de)(de)(de)(de)(de)(de)(de)振打(da)，使沉(chen)積(ji)在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振落(luo)，進(jin)人(ren)集灰(hui)斗(dou) 通(tong)過排(pai)灰(hui)裝(zhuang)置(zhi)放出，回收有(you)(you)物(wu)料(liao)，被(bei))凈化(hua)的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)排(pai)入大氣(qi)(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)工作原理是(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)場使(shi)煙(yan)氣發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣流(liu)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用下與氣流(liu)分離(li)。負極(ji)由不(bu)同(tong)斷面形(xing)狀(zhuang)的(de)(de)(de)金屬導(dao)線制成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形(xing)狀(zhuang)的(de)(de)(de)金屬板制成，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)性能受粉(fen)塵(chen)(chen)性質、設備(bei)構造和煙(yan)氣流(liu)速等三個(ge)因素的(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評價導(dao)電(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它對(dui)除塵(chen)(chen)效率有直接的(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其(qi)重返(fan)氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在塵(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)產(chan)生局(ju)部(bu)擊(ji)穿和放電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成除塵(chen)(chen)效率下降(jiang)。
