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(wo)式靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)(hua)法來收(shou)(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)(hua)工(gong)作上要(yao)是(shi)依靠(kao)電(dian)(dian)(dian)暈極(ji)和沉(chen)(chen)淀兩個系(xi)(xi)統(tong)來完成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)(ren)(ren)(ren)氣(qi)(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)(qi)流(liu)(liu)(liu)分布板以及折流(liu)(liu)(liu)板的(de)(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)(liu)能較(jiao)均(jun)勻地進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷面擴大的(de)(de)作用下，氣(qi)(qi)(qi)流(liu)(liu)(liu)速(su)度迅速(su)降(jiang)低(di)，其中有(you)些較(jiao)重(zhong)的(de)(de)塵(chen)(chen)粒便失去(qu)速(su)度而沉(chen)(chen)降(jiang)下來。進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)暈極(ji)通(tong)人(ren)(ren)(ren)(ren)高壓直流(liu)(liu)(liu)電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中存(cun)在(zai)(zai)(zai)大量的(de)(de)電(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)作用下趨向(xiang)本設(she)備陽(yang)極(ji)(正極(ji)、本設(she)備采(cai)用負高壓制)和陰極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)(zi)分別沉(chen)(chen)積在(zai)(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)上，通(tong)過設(she)備陰陽(yang)極(ji)振(zhen)打(da)系(xi)(xi)統(tong)的(de)(de)振(zhen)打(da)，使(shi)沉(chen)(chen)積在(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)上的(de)(de)粉(fen)塵(chen)(chen)振(zhen)落(luo)，進(jin)人(ren)(ren)(ren)(ren)集灰斗(dou) 通(tong)過排灰裝置放(fang)出，回收(shou)(shou)有(you)物料，被)凈(jing)化(hua)(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作(zuo)原理是利用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)(qi)流(liu)中的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與氣(qi)(qi)(qi)流(liu)分離。負極由不(bu)同斷面形狀的(de)(de)金屬導(dao)線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形狀的(de)(de)金屬板制(zhi)成(cheng)，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能(neng)受(shou)粉塵(chen)(chen)性質、設備(bei)構造和煙氣(qi)(qi)(qi)流(liu)速等三個(ge)因(yin)素的(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)效率有直接(jie)的(de)(de)影響(xiang)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使(shi)其重(zhong)返氣(qi)(qi)(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達(da)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易(yi)放出，在塵(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況(kuang)都(dou)會造成(cheng)除(chu)塵(chen)(chen)效率下(xia)降。

電除塵(chen)器的(de)(de)(de)基本原理(li)是利(li)用電力捕集煙氣中(zhong)的(de)(de)(de)粉(fen)(fen)塵(chen)，主要包括(kuo)以下四(si)個(ge)相互有關的(de)(de)(de)物(wu)理(li)過程: (1) 氣體(ti)的(de)(de)(de)電離。(2) 粉(fen)(fen)塵(chen)的(de)(de)(de)荷電。(3) 荷電粉(fen)(fen)塵(chen)向電極移動。(4) 荷電粉(fen)(fen)塵(chen)的(de)(de)(de)捕集。
