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(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)中的(de)(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)(jing)化(hua)工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極和沉(chen)淀兩個系(xi)統(tong)來(lai)完成的(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)(liu)分(fen)布板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)(de)(de)(de)調(diao)整后(hou)，使(shi)(shi)氣(qi)(qi)流(liu)(liu)能(neng)較均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷(duan)面(mian)擴大(da)(da)的(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)流(liu)(liu)速度迅速降低，其中有些較重(zhong)的(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)(li)便失去速度而沉(chen)降下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極通(tong)人(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈(yun)極附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)體中存在大(da)(da)量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)(li)在電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下趨(qu)向本設備(bei)(bei)陽極(正極、本設備(bei)(bei)采用(yong)(yong)負(fu)高壓(ya)制)和陰(yin)極(負(fu)極) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別(bie)沉(chen)積在相(xiang)應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極上，通(tong)過設備(bei)(bei)陰(yin)陽極振(zhen)打系(xi)統(tong)的(de)(de)(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極上的(de)(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗 通(tong)過排灰裝(zhuang)置放(fang)出(chu)，回(hui)收有物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)體排入大(da)(da)氣(qi)(qi)。

工作原(yuan)理(li)

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)工作原理是利用高壓(ya)電(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)(liu)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作用下(xia)(xia)與氣(qi)流(liu)(liu)(liu)分離。負(fu)極(ji)由(you)不同斷(duan)面形狀的(de)(de)(de)(de)金(jin)屬導(dao)線制成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形狀的(de)(de)(de)(de)金(jin)屬板制成(cheng)(cheng)，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備(bei)構造(zao)(zao)和煙(yan)氣(qi)流(liu)(liu)(liu)速等三個(ge)因素的(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標，它對除塵(chen)(chen)效率(lv)有直接的(de)(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)(liu)(liu)。比電(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)層之間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部(bu)擊(ji)穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)現(xian)象。這些情況都(dou)會造(zao)(zao)成(cheng)(cheng)除塵(chen)(chen)效率(lv)下(xia)(xia)降。

電除塵器的基本原(yuan)理是(shi)利用(yong)電力(li)捕集煙氣(qi)中的粉塵，主要包括以下四個相互有關的物理過程: (1) 氣(qi)體(ti)的電離(li)。(2) 粉塵的荷(he)電。(3) 荷(he)電粉塵向電極移(yi)動。(4) 荷(he)電粉塵的捕集。
