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)靜電(dian)(dian)(dian)(dian)(dian)除塵器是以靜電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)(lai)收捕廢(fei)氣(qi)(qi)中的(de)(de)(de)(de)(de)粉(fen)(fen)(fen)塵，它(ta)的(de)(de)(de)(de)(de)凈化工作上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極和(he)沉(chen)淀兩個系統來(lai)(lai)完成的(de)(de)(de)(de)(de)，當含塵氣(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含塵氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流(liu)(liu)(liu)分布板以及折流(liu)(liu)(liu)板的(de)(de)(de)(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)流(liu)(liu)(liu)能(neng)較均(jun)勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫斷面擴大(da)(da)的(de)(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)流(liu)(liu)(liu)速度(du)迅速降(jiang)(jiang)低，其中有些較重的(de)(de)(de)(de)(de)塵粒(li)便失去速度(du)而沉(chen)降(jiang)(jiang)下(xia)來(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含塵氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極通人(ren)(ren)高(gao)壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極附近產生電(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中存在(zai)(zai)(zai)大(da)(da)量(liang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)(fen)(fen)塵結合起來(lai)(lai)，使(shi)塵粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵粒(li)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作用下(xia)趨向(xiang)本設備(bei)陽(yang)極(正極、本設備(bei)采(cai)用負高(gao)壓制)和(he)陰極(負極) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積在(zai)(zai)(zai)相(xiang)應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極上，通過設備(bei)陰陽(yang)極振打系統的(de)(de)(de)(de)(de)振打，使(shi)沉(chen)積在(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極上的(de)(de)(de)(de)(de)粉(fen)(fen)(fen)塵振落，進(jin)人(ren)(ren)集(ji)灰斗 通過排灰裝(zhuang)置放出，回(hui)收有物料，被)凈化的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排入(ru)大(da)(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的工作原理是(shi)利用高壓電(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)(qi)(qi)流中的粉塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣(qi)(qi)(qi)流分離(li)。負極(ji)由不(bu)同(tong)斷面形(xing)狀(zhuang)的金(jin)屬(shu)導(dao)線制成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不(bu)同(tong)幾何形(xing)狀(zhuang)的金(jin)屬(shu)板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的性能受(shou)粉塵(chen)(chen)性質、設備(bei)構造和煙氣(qi)(qi)(qi)流速等三(san)個因素的影響。粉塵(chen)(chen)的比(bi)電(dian)(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)(dian)性的指標，它對除(chu)塵(chen)(chen)效率有直接的影響。比(bi)電(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)粒難(nan)以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)(qi)(qi)流。比(bi)電(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的塵(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)出，在塵(chen)(chen)層(ceng)之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)壓梯度(du)會(hui)產生局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)除(chu)塵(chen)(chen)效率下降。

電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)基本原理是利用電(dian)(dian)力(li)捕(bu)集(ji)煙氣中的(de)(de)粉塵(chen)(chen)，主要包括以下(xia)四個相互有關(guan)的(de)(de)物理過(guo)程: (1) 氣體(ti)的(de)(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵(chen)(chen)的(de)(de)捕(bu)集(ji)。
