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)除塵(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)凈(jing)化法來收捕廢(fei)氣(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)暈極(ji)(ji)和(he)沉淀兩個系統來完成的(de)(de)(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)體進(jin)人(ren)(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)流(liu)能較(jiao)(jiao)均勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)作(zuo)用(yong)下(xia)(xia)，氣(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有些(xie)較(jiao)(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速(su)度而沉降下(xia)(xia)來。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)暈極(ji)(ji)通人(ren)(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)(ji)附(fu)近產(chan)生電(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)體中存在(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這(zhe)些(xie)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)(xia)趨向本設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)負高壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)分(fen)別沉積在(zai)相(xiang)應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備陰(yin)陽(yang)極(ji)(ji)振打系統的(de)(de)(de)(de)振打，使(shi)沉積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)(ren)(ren)集灰(hui)(hui)斗 通過排灰(hui)(hui)裝置(zhi)放(fang)出，回收有物料，被)凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)體排入(ru)大(da)氣(qi)(qi)。

工(gong)作(zuo)原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)工作原理是利用高(gao)壓電(dian)(dian)(dian)場使(shi)煙氣發(fa)生電(dian)(dian)(dian)離，氣流(liu)(liu)(liu)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用下(xia)與氣流(liu)(liu)(liu)分離。負極由(you)不(bu)(bu)同斷(duan)面形(xing)狀(zhuang)的(de)(de)(de)(de)金(jin)屬導(dao)線制(zhi)(zhi)成(cheng)(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正(zheng)極由(you)不(bu)(bu)同幾(ji)何形(xing)狀(zhuang)的(de)(de)(de)(de)金(jin)屬板制(zhi)(zhi)成(cheng)(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)性能受粉(fen)塵(chen)(chen)性質、設備構造和煙氣流(liu)(liu)(liu)速等三(san)個(ge)因素的(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性的(de)(de)(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)效(xiao)率有直接的(de)(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難(nan)以保(bao)持(chi)在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上，致使(shi)其重返氣流(liu)(liu)(liu)。比(bi)電(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)(bu)易放(fang)出，在(zai)塵(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)壓梯度(du)會產生局(ju)部(bu)擊(ji)穿(chuan)和放(fang)電(dian)(dian)(dian)現象。這些(xie)情況(kuang)都會造成(cheng)(cheng)除(chu)(chu)塵(chen)(chen)效(xiao)率下(xia)降(jiang)。

電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)基本原(yuan)理(li)是(shi)利(li)用電(dian)(dian)力捕集煙氣中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，主(zhu)要包括以(yi)下四個(ge)相互有(you)關的(de)(de)物理(li)過程: (1) 氣體的(de)(de)電(dian)(dian)離(li)。(2) 粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)(chen)(chen)(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)捕集。
