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(shi)靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)法來收捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈化(hua)(hua)工作上(shang)要(yao)是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)(he)沉(chen)淀兩個系統來完成的(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)(de)(de)(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)能較均勻(yun)地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷(duan)面擴大(da)的(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速度迅速降低，其(qi)中有(you)些(xie)較重的(de)(de)(de)(de)塵(chen)粒便失去速度而沉(chen)降下來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通(tong)人(ren)(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體中存(cun)在大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)(he)離(li)子(zi)(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)(he)離(li)子(zi)(zi)(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)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)粒在電(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)作用(yong)下趨(qu)向本設(she)備陽(yang)極(ji)(正極(ji)、本設(she)備采用(yong)負高壓(ya)制)和(he)(he)陰(yin)極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分別(bie)沉(chen)積在相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過(guo)設(she)備陰(yin)陽(yang)極(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)(zhen)落，進(jin)(jin)人(ren)(ren)集灰斗(dou) 通(tong)過(guo)排灰裝置放(fang)出，回收有(you)物料，被)凈化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體排入大(da)氣(qi)(qi)(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工作原理是(shi)利用高(gao)壓(ya)(ya)電(dian)(dian)(dian)場(chang)(chang)使煙(yan)(yan)氣(qi)發生(sheng)(sheng)電(dian)(dian)(dian)離(li)，氣(qi)流中(zhong)的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)(chang)作用下與(yu)氣(qi)流分離(li)。負極(ji)(ji)由(you)不同斷面形狀的(de)(de)金(jin)屬(shu)導(dao)線制(zhi)成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形狀的(de)(de)金(jin)屬(shu)板制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)性(xing)能受(shou)粉塵(chen)(chen)(chen)性(xing)質、設備構(gou)造和煙(yan)(yan)氣(qi)流速等三(san)個因素的(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效(xiao)率有直(zhi)接的(de)(de)影響。比(bi)電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難(nan)以保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流。比(bi)電(dian)(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易(yi)放出(chu)，在塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)壓(ya)(ya)梯(ti)度會產生(sheng)(sheng)局部擊(ji)穿和放電(dian)(dian)(dian)現(xian)象。這些(xie)情況都(dou)會造成除(chu)塵(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵器的(de)基本原理是利用電(dian)(dian)力捕集煙(yan)氣中的(de)粉塵，主要(yao)包括以下(xia)四(si)個(ge)相互有關的(de)物理過程(cheng): (1) 氣體的(de)電(dian)(dian)離。(2) 粉塵的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵向(xiang)電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵的(de)捕集。
