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)除塵(chen)(chen)(chen)(chen)器是(shi)(shi)以靜電(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收捕廢氣(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)，它(ta)的(de)(de)(de)凈(jing)(jing)化(hua)工作上(shang)要是(shi)(shi)依(yi)靠電(dian)(dian)(dian)暈(yun)極和(he)(he)沉(chen)淀(dian)兩個系統(tong)來(lai)完成(cheng)的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)體進(jin)人(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)體受到氣(qi)流(liu)(liu)分布(bu)板以及折流(liu)(liu)板的(de)(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)(liu)能較均勻(yun)地(di)進(jin)人(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)作用(yong)下，氣(qi)流(liu)(liu)速(su)度迅速(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)度而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)體由于電(dian)(dian)(dian)暈(yun)極通人(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)暈(yun)極附近產(chan)生電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)體中存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子和(he)(he)離(li)子，這些電(dian)(dian)(dian)子和(he)(he)離(li)子與進(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)結合起(qi)來(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作用(yong)下趨(qu)向本設(she)備陽(yang)極(正極、本設(she)備采用(yong)負高壓(ya)制)和(he)(he)陰(yin)極(負極) ， 釋放(fang)(fang)出電(dian)(dian)(dian)子分別(bie)沉(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)極上(shang)，通過設(she)備陰(yin)陽(yang)極振打系統(tong)的(de)(de)(de)振打，使(shi)沉(chen)積(ji)在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極上(shang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)振落，進(jin)人(ren)集灰(hui)斗(dou) 通過排灰(hui)裝置(zhi)放(fang)(fang)出，回收有(you)物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)體排入大(da)氣(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)工(gong)作(zuo)(zuo)原理是(shi)利(li)用(yong)高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)(zuo)用(yong)下(xia)與氣(qi)流(liu)(liu)分離(li)。負極(ji)由(you)不(bu)(bu)同斷(duan)面形狀的(de)(de)金屬導(dao)線(xian)制成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由(you)不(bu)(bu)同幾何形狀的(de)(de)金屬板制成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能(neng)受(shou)粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備構造和煙氣(qi)流(liu)(liu)速(su)等三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評(ping)價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有直(zhi)接的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒(li)難以保持(chi)在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)(shi)其重返氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易(yi)放(fang)出，在塵(chen)(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產(chan)生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些(xie)情況都會造成除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下(xia)降。

電(dian)除塵(chen)(chen)器的(de)基本原理(li)是(shi)利用電(dian)力捕(bu)(bu)集(ji)煙氣中的(de)粉塵(chen)(chen)，主要包括以(yi)下四(si)個相互(hu)有關(guan)的(de)物理(li)過(guo)程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)(chen)向電(dian)極(ji)移動。(4) 荷電(dian)粉塵(chen)(chen)的(de)捕(bu)(bu)集(ji)。
