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)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法(fa)來(lai)(lai)收(shou)捕廢(fei)氣(qi)中(zhong)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)(chen)(chen)淀兩個系統(tong)來(lai)(lai)完成的(de)(de)(de)，當含塵(chen)(chen)氣(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)體(ti)(ti)受到氣(qi)流分布板以(yi)及折流板的(de)(de)(de)調(diao)整后，使(shi)氣(qi)流能較均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴大(da)(da)的(de)(de)(de)作用下(xia)，氣(qi)流速度迅速降(jiang)低，其中(zhong)有(you)些較重的(de)(de)(de)塵(chen)(chen)粒便失去速度而沉(chen)(chen)(chen)降(jiang)下(xia)來(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)氣(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)體(ti)(ti)中(zhong)存(cun)在大(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下(xia)趨向本設備(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本設備(bei)采用負(fu)高壓制)和陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)(chen)(chen)積在相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過(guo)設備(bei)陰(yin)陽極(ji)(ji)振打(da)系統(tong)的(de)(de)(de)振打(da)，使(shi)沉(chen)(chen)(chen)積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振落，進(jin)人(ren)(ren)集灰斗 通過(guo)排灰裝(zhuang)置(zhi)放出(chu)，回(hui)收(shou)有(you)物料，被)凈化的(de)(de)(de)氣(qi)體(ti)(ti)排入(ru)大(da)(da)氣(qi)。

工作原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)工作原理是(shi)(shi)利(li)用高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用下與(yu)氣(qi)(qi)流分離。負(fu)極由不同斷面(mian)形狀的(de)(de)金(jin)屬導線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正(zheng)極由不同幾何形狀的(de)(de)金(jin)屬板制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙(yan)氣(qi)(qi)流速(su)等三個因素的(de)(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有(you)直接(jie)的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度會產(chan)生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下降(jiang)。

電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)基本原理是利用(yong)電(dian)(dian)(dian)力(li)捕(bu)集(ji)煙氣中的(de)(de)粉塵(chen)(chen)(chen)，主要(yao)包括以下(xia)四個相互有(you)關的(de)(de)物(wu)理過程(cheng): (1) 氣體的(de)(de)電(dian)(dian)(dian)離。(2) 粉塵(chen)(chen)(chen)的(de)(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉塵(chen)(chen)(chen)向(xiang)電(dian)(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)(dian)粉塵(chen)(chen)(chen)的(de)(de)捕(bu)集(ji)。
