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)除塵(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢(fei)氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈化工作上(shang)要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)沉淀兩個系統(tong)來完成的(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流(liu)分(fen)布板以(yi)及折流(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大(da)的(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)流(liu)速(su)(su)度迅速(su)(su)降低，其中有些(xie)較(jiao)重的(de)(de)(de)塵(chen)粒便失去速(su)(su)度而沉降下來。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通(tong)人(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附(fu)近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離子，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)子和(he)離子與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵(chen)結合起來，使(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用(yong)下趨向本設(she)備(bei)陽(yang)(yang)極(ji)(正極(ji)、本設(she)備(bei)采用(yong)負高(gao)壓(ya)制(zhi))和(he)陰(yin)極(ji)(負極(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉積在(zai)(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設(she)備(bei)陰(yin)陽(yang)(yang)極(ji)振(zhen)打系統(tong)的(de)(de)(de)振(zhen)打，使(shi)沉積在(zai)(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉塵(chen)振(zhen)落(luo)，進人(ren)(ren)集灰斗 通(tong)過排灰裝置(zhi)放(fang)出(chu)，回收有物(wu)料，被)凈化的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜(jing)(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原理是(shi)利用高(gao)壓電(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)離，氣(qi)流(liu)(liu)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣(qi)流(liu)(liu)分(fen)離。負極(ji)(ji)由(you)不(bu)同斷面形(xing)(xing)狀(zhuang)的(de)(de)(de)金屬導線(xian)制成(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同幾何形(xing)(xing)狀(zhuang)的(de)(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜(jing)(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性能受(shou)粉塵(chen)(chen)(chen)(chen)性質、設備構造(zao)(zao)和(he)(he)煙氣(qi)流(liu)(liu)速等三個(ge)因素(su)的(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)性的(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)(chen)效率有直接(jie)的(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致(zhi)使其重(zhong)返氣(qi)流(liu)(liu)。比(bi)(bi)電(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿(chuan)和(he)(he)放電(dian)(dian)現(xian)象(xiang)。這些情況都會(hui)造(zao)(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵器的(de)基本原(yuan)理(li)是利用電(dian)(dian)力捕(bu)集(ji)煙氣中的(de)粉塵，主(zhu)要(yao)包括以下四(si)個相互有(you)關的(de)物理(li)過程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉塵的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵的(de)捕(bu)集(ji)。
