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)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器是(shi)(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法(fa)來收捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)凈化(hua)工作上(shang)要是(shi)(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉淀兩(liang)個系統(tong)來完成的(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)(qi)流(liu)能較均(jun)勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴大(da)的(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速(su)(su)度(du)迅速(su)(su)降低，其中有(you)些(xie)較重(zhong)的(de)(de)(de)塵(chen)粒便失去速(su)(su)度(du)而沉降下(xia)來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中存在大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)(li)(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)(li)(li)子(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)結(jie)合起來，使(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下(xia)趨向本(ben)(ben)設(she)(she)備(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)(ben)設(she)(she)備(bei)采用負(fu)高壓制)和陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積(ji)(ji)在相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過(guo)設(she)(she)備(bei)陰(yin)陽極(ji)(ji)振(zhen)(zhen)打(da)系統(tong)的(de)(de)(de)振(zhen)(zhen)打(da)，使(shi)沉積(ji)(ji)在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)振(zhen)(zhen)落，進(jin)(jin)人(ren)(ren)集灰(hui)斗 通過(guo)排灰(hui)裝置放(fang)出，回收有(you)物(wu)料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工作原理是利用高(gao)(gao)壓電(dian)(dian)場(chang)(chang)使(shi)煙氣(qi)發(fa)生(sheng)電(dian)(dian)離，氣(qi)流中的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)(chang)作用下與氣(qi)流分離。負極(ji)(ji)由不(bu)同斷面(mian)形(xing)狀(zhuang)的(de)(de)金屬導線制(zhi)成，叫放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾(ji)何形(xing)狀(zhuang)的(de)(de)金屬板(ban)制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能(neng)受粉塵(chen)(chen)(chen)性(xing)質、設(she)備(bei)構造(zao)和煙氣(qi)流速等(deng)三個因素的(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)阻是評價導電(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)影響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上(shang)，致使(shi)其重返氣(qi)流。比電(dian)(dian)阻過高(gao)(gao)，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易(yi)放出，在塵(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)壓梯度會產生(sheng)局部擊(ji)穿和放電(dian)(dian)現象(xiang)。這些情況都會造(zao)成除(chu)(chu)塵(chen)(chen)(chen)效率(lv)下降(jiang)。

電(dian)(dian)除塵(chen)(chen)器的(de)(de)基(ji)本原(yuan)理(li)是(shi)利用電(dian)(dian)力捕集煙氣中(zhong)的(de)(de)粉(fen)塵(chen)(chen)，主(zhu)要包括以下四(si)個相互(hu)有關的(de)(de)物理(li)過(guo)程: (1) 氣體的(de)(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集。
