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)除(chu)塵(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈化(hua)法來收(shou)捕廢氣(qi)(qi)中(zhong)的(de)粉塵(chen)，它的(de)凈化(hua)工作上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉淀(dian)兩個系(xi)統(tong)來完成的(de)，當含塵(chen)氣(qi)(qi)體進人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)體受到氣(qi)(qi)流分(fen)布板以及折流板的(de)調整后，使(shi)氣(qi)(qi)流能(neng)較(jiao)均勻地(di)進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷(duan)面(mian)擴大的(de)作用下(xia)，氣(qi)(qi)流速(su)度迅速(su)降(jiang)(jiang)低，其中(zhong)有些(xie)較(jiao)重(zhong)的(de)塵(chen)粒便(bian)失去速(su)度而沉降(jiang)(jiang)下(xia)來。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)(tong)人(ren)(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)體中(zhong)存(cun)在大量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與(yu)進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉塵(chen)結合(he)起來，使(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作用下(xia)趨向本設(she)備(bei)陽極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)采用負高壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉積在相應的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)(tong)過設(she)備(bei)陰陽極(ji)(ji)振打系(xi)統(tong)的(de)振打，使(shi)沉積在陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)粉塵(chen)振落，進人(ren)(ren)集灰(hui)(hui)斗 通(tong)(tong)過排(pai)灰(hui)(hui)裝置放出，回(hui)收(shou)有物料，被)凈化(hua)的(de)氣(qi)(qi)體排(pai)入大氣(qi)(qi)。

工作原理

靜電(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作(zuo)(zuo)原理是利用高壓(ya)電(dian)場使(shi)煙氣(qi)發(fa)生(sheng)電(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)在(zai)(zai)(zai)電(dian)場作(zuo)(zuo)用下與氣(qi)流(liu)分離。負極(ji)(ji)由不同斷面形(xing)狀的(de)(de)(de)金屬導線(xian)制(zhi)(zhi)成，叫放電(dian)電(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形(xing)狀的(de)(de)(de)金屬板制(zhi)(zhi)成，叫集塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)。靜電(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備(bei)構造(zao)(zao)和煙氣(qi)流(liu)速等三個因(yin)素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)阻(zu)是評價導電(dian)性(xing)的(de)(de)(de)指標，它(ta)對(dui)除塵(chen)(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)影響。比電(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持在(zai)(zai)(zai)集塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)上(shang)，致使(shi)其重返氣(qi)流(liu)。比電(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)(chen)(chen)電(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)荷不易放出，在(zai)(zai)(zai)塵(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)壓(ya)梯度(du)會產生(sheng)局部擊穿和放電(dian)現象。這些情況都會造(zao)(zao)成除塵(chen)(chen)(chen)(chen)效率(lv)下降。

電除塵器的(de)(de)基(ji)本原(yuan)理(li)是利用電力捕(bu)集(ji)煙氣中的(de)(de)粉塵，主要包括以(yi)下四個相互有(you)關的(de)(de)物理(li)過(guo)程: (1) 氣體(ti)的(de)(de)電離。(2) 粉塵的(de)(de)荷電。(3) 荷電粉塵向電極移動。(4) 荷電粉塵的(de)(de)捕(bu)集(ji)。
