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)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)(jing)化法來收捕廢氣(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈(jing)(jing)化工作上(shang)要是依靠電(dian)(dian)(dian)(dian)暈極(ji)和(he)沉(chen)(chen)淀兩個系統來完成的(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體進(jin)(jin)人(ren)(ren)氣(qi)刺叭(ba)時，含(han)塵(chen)(chen)(chen)氣(qi)體受(shou)到(dao)氣(qi)流分布板以及折流板的(de)(de)調整后(hou)，使(shi)氣(qi)流能較(jiao)均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷面(mian)擴(kuo)大的(de)(de)作用(yong)下，氣(qi)流速度迅速降低，其中(zhong)有(you)些較(jiao)重(zhong)的(de)(de)塵(chen)(chen)(chen)粒(li)便失去(qu)速度而沉(chen)(chen)降下來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體由于電(dian)(dian)(dian)(dian)暈極(ji)通人(ren)(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)體中(zhong)存在(zai)(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)結合(he)起來，使(shi)塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(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(cai)用(yong)負高(gao)壓制)和(he)陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉(chen)(chen)積在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設備(bei)陰(yin)陽極(ji)振(zhen)(zhen)打系統的(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉塵(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)(jin)人(ren)(ren)集灰(hui)斗 通過排灰(hui)裝置放出，回收有(you)物料，被)凈(jing)(jing)化的(de)(de)氣(qi)體排入大氣(qi)。

工作原(yuan)理

靜電(dian)除塵(chen)(chen)(chen)器的(de)(de)工(gong)作(zuo)原理(li)是(shi)利用(yong)高(gao)壓電(dian)場使煙氣(qi)發生(sheng)(sheng)電(dian)離(li)(li)，氣(qi)流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)在(zai)電(dian)場作(zuo)用(yong)下與氣(qi)流(liu)分離(li)(li)。負極(ji)(ji)由(you)不(bu)同(tong)斷面形(xing)狀(zhuang)的(de)(de)金(jin)屬(shu)(shu)導(dao)線制成(cheng)(cheng)，叫(jiao)放電(dian)電(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同(tong)幾何形(xing)狀(zhuang)的(de)(de)金(jin)屬(shu)(shu)板制成(cheng)(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)極(ji)(ji)。靜電(dian)除塵(chen)(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設(she)備(bei)構造(zao)和煙氣(qi)流(liu)速等三個因素的(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)阻是(shi)評價導(dao)電(dian)性的(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)影(ying)響。比電(dian)阻過(guo)低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)(chen)電(dian)極(ji)(ji)上，致(zhi)使其重返氣(qi)流(liu)。比電(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)(chen)電(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)層之間(jian)形(xing)成(cheng)(cheng)電(dian)壓梯度會產(chan)生(sheng)(sheng)局部擊(ji)穿和放電(dian)現象。這(zhe)些情(qing)況都會造(zao)成(cheng)(cheng)除塵(chen)(chen)(chen)效(xiao)率下降。

電(dian)除塵器的(de)(de)基本(ben)原理(li)是(shi)利(li)用電(dian)力捕集(ji)煙(yan)氣(qi)中的(de)(de)粉(fen)塵，主要包括以下四個(ge)相互(hu)有關的(de)(de)物(wu)理(li)過程: (1) 氣(qi)體的(de)(de)電(dian)離。(2) 粉(fen)塵的(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵的(de)(de)捕集(ji)。
