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(jing)電(dian)(dian)除塵(chen)器是(shi)以靜(jing)電(dian)(dian)凈化(hua)(hua)法來收捕(bu)廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈化(hua)(hua)工(gong)作(zuo)上要是(shi)依靠電(dian)(dian)暈(yun)(yun)極(ji)和(he)(he)沉淀兩個系統來完(wan)成的(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)刺(ci)叭時，含塵(chen)氣(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)流分布板(ban)以及折流板(ban)的(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)流能較均勻地進(jin)(jin)人(ren)電(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)(da)的(de)(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)流速度迅速降低，其(qi)中(zhong)有(you)些較重的(de)(de)(de)(de)塵(chen)粒(li)便失去速度而沉降下(xia)來。進(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)(de)(de)含塵(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)(yun)極(ji)通(tong)(tong)(tong)人(ren)高壓直流電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈(yun)(yun)極(ji)附(fu)近產生電(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)大(da)(da)量的(de)(de)(de)(de)電(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)，這些電(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)與進(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)結合起來，使(shi)塵(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)趨向本設備陽(yang)(yang)極(ji)(正極(ji)、本設備采用(yong)負高壓制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放(fang)(fang)出電(dian)(dian)子(zi)(zi)分別(bie)沉積在(zai)(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)極(ji)上，通(tong)(tong)(tong)過設備陰陽(yang)(yang)極(ji)振(zhen)打(da)系統的(de)(de)(de)(de)振(zhen)打(da)，使(shi)沉積在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)極(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗 通(tong)(tong)(tong)過排灰裝置(zhi)放(fang)(fang)出，回收有(you)物料，被)凈化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大(da)(da)氣(qi)(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)工作原理是(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用下與(yu)氣(qi)(qi)流分(fen)離(li)。負(fu)極(ji)(ji)由不同(tong)(tong)斷面形狀的(de)(de)(de)金屬(shu)導線制成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)(tong)幾何(he)形狀的(de)(de)(de)金屬(shu)板制成，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)性能受粉塵(chen)(chen)性質、設備構造和煙氣(qi)(qi)流速(su)等(deng)三(san)個因素的(de)(de)(de)影(ying)響。粉塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是(shi)評(ping)價導電(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對(dui)除(chu)塵(chen)(chen)效率(lv)(lv)有直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難(nan)以保(bao)持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返(fan)氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易(yi)放出(chu)，在塵(chen)(chen)層之間(jian)形成電(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)產(chan)生局部擊穿和放電(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些情況都會(hui)造成除(chu)塵(chen)(chen)效率(lv)(lv)下降。

電(dian)(dian)除塵(chen)器的基本原理是利用(yong)電(dian)(dian)力捕集(ji)煙氣(qi)中的粉塵(chen)，主要包括以下(xia)四(si)個(ge)相互有關(guan)的物理過程: (1) 氣(qi)體的電(dian)(dian)離。(2) 粉塵(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵(chen)的捕集(ji)。
