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)除(chu)塵(chen)(chen)器是以(yi)靜電(dian)(dian)凈化法來收捕廢氣(qi)(qi)(qi)中(zhong)的(de)粉(fen)(fen)塵(chen)(chen)，它(ta)的(de)凈化工(gong)作上要是依靠電(dian)(dian)暈(yun)極(ji)和沉淀兩(liang)個系統來完成的(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)刺(ci)叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流分布板以(yi)及(ji)折(zhe)流板的(de)調整后，使氣(qi)(qi)(qi)流能較均(jun)勻地進人(ren)電(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大的(de)作用(yong)下，氣(qi)(qi)(qi)流速度迅速降低，其中(zhong)有些(xie)較重的(de)塵(chen)(chen)粒便失去速度而(er)沉降下來。進人(ren)電(dian)(dian)場(chang)(chang)的(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)暈(yun)極(ji)通(tong)人(ren)高(gao)壓直流電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈(yun)極(ji)附近產(chan)生電(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)氣(qi)(qi)(qi)體(ti)中(zhong)存在(zai)(zai)大量的(de)電(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這(zhe)些(xie)電(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與(yu)進人(ren)電(dian)(dian)場(chang)(chang)的(de)粉(fen)(fen)塵(chen)(chen)結(jie)合起來，使塵(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)場(chang)(chang)力(li)的(de)作用(yong)下趨向本設(she)備陽極(ji)(正(zheng)極(ji)、本設(she)備采用(yong)負高(gao)壓制)和陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)子(zi)(zi)分別沉積(ji)在(zai)(zai)相應的(de)電(dian)(dian)極(ji)上，通(tong)過(guo)設(she)備陰(yin)陽極(ji)振(zhen)(zhen)打系統的(de)振(zhen)(zhen)打，使沉積(ji)在(zai)(zai)陰(yin)陽電(dian)(dian)極(ji)上的(de)粉(fen)(fen)塵(chen)(chen)振(zhen)(zhen)落，進人(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置放出，回收有物料，被(bei))凈化的(de)氣(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)工作原理(li)是(shi)利用(yong)高(gao)(gao)壓電(dian)(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用(yong)下與氣流(liu)分(fen)離。負極(ji)由(you)不同(tong)斷面形狀的(de)金屬導線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何形狀的(de)金屬板(ban)制(zhi)成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)性(xing)(xing)能(neng)受粉塵(chen)(chen)性(xing)(xing)質(zhi)、設備構造和煙氣流(liu)速等三個因(yin)素(su)的(de)影(ying)響。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)(xing)的(de)指(zhi)標，它對除(chu)塵(chen)(chen)效率有直接的(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保(bao)持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使其重返(fan)氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過高(gao)(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)層之(zhi)間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產(chan)生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些情況都(dou)會造成(cheng)(cheng)除(chu)塵(chen)(chen)效率下降。

電(dian)除塵(chen)器的(de)基本原理(li)是利(li)用電(dian)力捕集煙氣中的(de)粉(fen)(fen)塵(chen)，主要包括以下四個相互有關的(de)物(wu)理(li)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。(4) 荷電(dian)粉(fen)(fen)塵(chen)的(de)捕集。
