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(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收(shou)捕廢(fei)氣中(zhong)的(de)粉塵(chen)，它的(de)凈化工(gong)作(zuo)(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)沉(chen)淀兩個系統來(lai)完成的(de)，當含塵(chen)氣體(ti)進(jin)人(ren)(ren)(ren)氣刺叭時，含塵(chen)氣體(ti)受到氣流(liu)(liu)分布板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)調整后(hou)，使氣流(liu)(liu)能較均勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴(kuo)大的(de)作(zuo)(zuo)用下，氣流(liu)(liu)速(su)度迅(xun)速(su)降低，其中(zhong)有些較重(zhong)的(de)塵(chen)粒便失去速(su)度而(er)沉(chen)降下來(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)含塵(chen)氣體(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通人(ren)(ren)(ren)高(gao)壓(ya)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使氣體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)氣體(ti)中(zhong)存(cun)在大量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)粉塵(chen)結合(he)起來(lai)，使塵(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)場力的(de)作(zuo)(zuo)用下趨向本設備陽極(ji)(正極(ji)、本設備采(cai)用負(fu)高(gao)壓(ya)制)和(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別(bie)沉(chen)積在相應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設備陰(yin)陽極(ji)振(zhen)打系統的(de)振(zhen)打，使沉(chen)積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)粉塵(chen)振(zhen)落，進(jin)人(ren)(ren)(ren)集灰斗 通過排灰裝置(zhi)放出，回收(shou)有物料(liao)，被)凈化的(de)氣體(ti)排入大氣。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣流(liu)分離(li)。負極由不(bu)同斷面(mian)形(xing)狀(zhuang)(zhuang)的(de)(de)(de)金(jin)屬導線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形(xing)狀(zhuang)(zhuang)的(de)(de)(de)金(jin)屬板制(zhi)成(cheng)(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受粉(fen)(fen)塵(chen)(chen)(chen)性(xing)質、設備構造和煙氣流(liu)速等(deng)三個(ge)因素的(de)(de)(de)影(ying)響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對(dui)除(chu)(chu)塵(chen)(chen)(chen)效率有直接(jie)的(de)(de)(de)影(ying)響。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難(nan)以保持在(zai)(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重(zhong)返氣流(liu)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況都會造成(cheng)(cheng)除(chu)(chu)塵(chen)(chen)(chen)效率下降。

電(dian)除塵(chen)(chen)(chen)器的基本原理是(shi)利(li)用(yong)電(dian)力捕集煙氣(qi)中的粉(fen)塵(chen)(chen)(chen)，主要(yao)包(bao)括(kuo)以下(xia)四個相互(hu)有關的物理過程: (1) 氣(qi)體的電(dian)離。(2) 粉(fen)塵(chen)(chen)(chen)的荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)(chen)(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)塵(chen)(chen)(chen)的捕集。
