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)(dian)(dian)除塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣中的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈化(hua)工作(zuo)上要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉(chen)(chen)淀兩(liang)個系統來(lai)完(wan)成(cheng)的(de)(de)，當含(han)塵(chen)氣體(ti)(ti)(ti)(ti)進(jin)人氣刺叭時，含(han)塵(chen)氣體(ti)(ti)(ti)(ti)受到氣流分布板(ban)以及折(zhe)流板(ban)的(de)(de)調(diao)整(zheng)后(hou)，使(shi)(shi)氣流能(neng)較均勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面(mian)擴大(da)的(de)(de)作(zuo)用下，氣流速(su)度(du)迅速(su)降低，其中有些較重的(de)(de)塵(chen)粒便失(shi)去(qu)速(su)度(du)而沉(chen)(chen)降下來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)氣體(ti)(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)(shi)氣體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣體(ti)(ti)(ti)(ti)中存在大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子與進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)結合起來(lai)，使(shi)(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用下趨(qu)向本設(she)備(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)備(bei)采(cai)用負高壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)(chen)積(ji)在相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過(guo)(guo)設(she)備(bei)陰(yin)陽極(ji)(ji)振打系統的(de)(de)振打，使(shi)(shi)沉(chen)(chen)積(ji)在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉(fen)塵(chen)振落，進(jin)人集灰(hui)斗 通過(guo)(guo)排灰(hui)裝置(zhi)放(fang)出，回收有物(wu)料，被)凈化(hua)的(de)(de)氣體(ti)(ti)(ti)(ti)排入大(da)氣。

工作原理

靜電(dian)(dian)(dian)除塵器(qi)的工作原理是(shi)利(li)用高(gao)壓電(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)離，氣流(liu)中的粉(fen)(fen)塵荷(he)電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作用下(xia)與(yu)氣流(liu)分(fen)離。負極(ji)(ji)由(you)不(bu)同(tong)斷面形(xing)狀(zhuang)的金(jin)屬(shu)導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同(tong)幾何形(xing)狀(zhuang)的金(jin)屬(shu)板制成，叫集(ji)塵電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵器(qi)的性(xing)能受粉(fen)(fen)塵性(xing)質(zhi)、設(she)備構造和煙氣流(liu)速等三個因素(su)的影響(xiang)。粉(fen)(fen)塵的比(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性(xing)的指標，它對(dui)除塵效率有直接的影響(xiang)。比(bi)電(dian)(dian)(dian)阻過(guo)(guo)低，塵粒難以(yi)保持在(zai)(zai)集(ji)塵電(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣流(liu)。比(bi)電(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集(ji)塵電(dian)(dian)(dian)極(ji)(ji)的塵粒電(dian)(dian)(dian)荷(he)不(bu)易放出，在(zai)(zai)塵層之間(jian)形(xing)成電(dian)(dian)(dian)壓梯度會產(chan)生局(ju)部擊穿(chuan)和放電(dian)(dian)(dian)現(xian)象。這些(xie)情況都會造成除塵效率下(xia)降。

電(dian)除(chu)塵(chen)器的(de)基本原理是利用電(dian)力捕集煙氣中(zhong)的(de)粉(fen)(fen)塵(chen)，主要包括以下四個相互有關的(de)物理過程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)向電(dian)極移動(dong)。(4) 荷電(dian)粉(fen)(fen)塵(chen)的(de)捕集。
