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)除塵(chen)(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)凈化(hua)(hua)法來(lai)收捕廢(fei)氣(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈化(hua)(hua)工作上要是(shi)依靠電(dian)(dian)暈(yun)極(ji)和(he)(he)沉淀兩個系(xi)統(tong)(tong)來(lai)完成的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)(liu)分布(bu)板(ban)(ban)以及折(zhe)流(liu)(liu)板(ban)(ban)的(de)(de)(de)調整(zheng)后，使氣(qi)(qi)流(liu)(liu)能較均勻(yun)地進(jin)人(ren)(ren)電(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)流(liu)(liu)速(su)度(du)迅速(su)降低，其(qi)中有(you)些較重的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速(su)度(du)而沉降下(xia)來(lai)。進(jin)人(ren)(ren)電(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高壓直(zhi)流(liu)(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)子(zi)和(he)(he)離(li)子(zi)，這些電(dian)(dian)子(zi)和(he)(he)離(li)子(zi)與進(jin)人(ren)(ren)電(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)(chen)粒帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下(xia)趨向本(ben)設(she)備(bei)陽(yang)極(ji)(正極(ji)、本(ben)設(she)備(bei)采用(yong)負高壓制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)子(zi)分別沉積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)極(ji)上，通過設(she)備(bei)陰陽(yang)極(ji)振打系(xi)統(tong)(tong)的(de)(de)(de)振打，使沉積(ji)在(zai)陰陽(yang)電(dian)(dian)極(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振落，進(jin)人(ren)(ren)集(ji)灰斗 通過排(pai)(pai)灰裝置(zhi)放出(chu)，回收有(you)物料(liao)，被)凈化(hua)(hua)的(de)(de)(de)氣(qi)(qi)體(ti)排(pai)(pai)入大(da)氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的工作原理是利用(yong)高壓(ya)電(dian)(dian)(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)下與氣流(liu)(liu)分離。負(fu)極(ji)由不(bu)同斷面(mian)形(xing)狀(zhuang)的金屬(shu)導(dao)線(xian)制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何(he)形(xing)狀(zhuang)的金屬(shu)板(ban)制成(cheng)，叫集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的性(xing)能受粉(fen)塵(chen)性(xing)質、設備構造(zao)和(he)煙氣流(liu)(liu)速等三(san)個(ge)因素(su)的影(ying)響(xiang)。粉(fen)塵(chen)的比電(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)性(xing)的指標(biao)，它對除(chu)塵(chen)效率(lv)有(you)直(zhi)接的影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒難以保持(chi)在集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣流(liu)(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過高，到(dao)達集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)的塵(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)層之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生(sheng)局部擊穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成(cheng)除(chu)塵(chen)效率(lv)下降。

電除塵器(qi)的(de)基本原理(li)(li)是利用電力捕集煙氣中(zhong)的(de)粉(fen)塵，主要包括以下四個相(xiang)互有(you)關的(de)物(wu)理(li)(li)過程: (1) 氣體(ti)的(de)電離。(2) 粉(fen)塵的(de)荷(he)電。(3) 荷(he)電粉(fen)塵向電極移動。(4) 荷(he)電粉(fen)塵的(de)捕集。
