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(shi)靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化工作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉淀兩個系統來完成(cheng)的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)進人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分布板以及(ji)折流板的(de)(de)(de)(de)調整(zheng)后，使氣(qi)(qi)流能(neng)較均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷面擴大的(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)流速度(du)迅速降(jiang)低，其(qi)中有(you)些較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失去(qu)速度(du)而(er)沉降(jiang)下來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)體(ti)中存(cun)在(zai)(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合(he)起來，使塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用(yong)下趨(qu)向本設備(bei)陽極(ji)(正(zheng)極(ji)、本設備(bei)采用(yong)負(fu)高壓制)和陰極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別(bie)沉積(ji)在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設備(bei)陰陽極(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)振(zhen)(zhen)打，使沉積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)(zhen)落(luo)，進人(ren)集灰斗 通過排灰裝置(zhi)放(fang)出，回收(shou)有(you)物(wu)料，被)凈化的(de)(de)(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)除塵(chen)(chen)器的工作原理是(shi)利用高(gao)壓電(dian)(dian)(dian)場使煙(yan)氣(qi)(qi)發(fa)生電(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的粉塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與(yu)氣(qi)(qi)流(liu)分離(li)。負(fu)極(ji)(ji)由不同(tong)(tong)斷面形狀的金屬導(dao)線制成，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不同(tong)(tong)幾(ji)何(he)形狀的金屬板制成，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器的性能(neng)受粉塵(chen)(chen)性質、設備(bei)構造(zao)和煙(yan)氣(qi)(qi)流(liu)速等三(san)個因(yin)素的影響。粉塵(chen)(chen)的比(bi)(bi)電(dian)(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)(dian)性的指標，它對除塵(chen)(chen)效率(lv)有直接的影響。比(bi)(bi)電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒(li)難以(yi)保持(chi)在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其重(zhong)返氣(qi)(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)層之(zhi)間(jian)形成電(dian)(dian)(dian)壓梯(ti)度會(hui)產生局部(bu)擊(ji)穿和放(fang)電(dian)(dian)(dian)現象(xiang)。這些(xie)情況都會(hui)造(zao)成除塵(chen)(chen)效率(lv)下降。

電(dian)除塵(chen)器的基本(ben)原理(li)是利用電(dian)力(li)捕集煙氣中的粉(fen)(fen)塵(chen)，主要(yao)包括以下(xia)四個相互(hu)有關的物(wu)理(li)過程: (1) 氣體的電(dian)離。(2) 粉(fen)(fen)塵(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵(chen)向(xiang)電(dian)極移動。(4) 荷(he)電(dian)粉(fen)(fen)塵(chen)的捕集。
