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)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)凈化法來收捕(bu)廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈化工(gong)作(zuo)上(shang)(shang)要是(shi)依靠電(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀兩個系統來完成(cheng)的(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板(ban)(ban)以及折流(liu)(liu)板(ban)(ban)的(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)能較均勻(yun)地進(jin)人(ren)電(dian)(dian)(dian)場。在(zai)橫斷面(mian)擴大(da)的(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)流(liu)(liu)速(su)度(du)迅速(su)降(jiang)低，其中有些較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)粒便失(shi)去速(su)度(du)而沉(chen)降(jiang)下來。進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通(tong)人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中存在(zai)大(da)量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)，這些電(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合起來，使塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下趨向本(ben)設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備采用負高壓制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)子(zi)分別沉(chen)積(ji)在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，通(tong)過設備陰(yin)陽(yang)極(ji)(ji)振打系統的(de)(de)(de)(de)振打，使沉(chen)積(ji)在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)集灰(hui)斗 通(tong)過排灰(hui)裝置放(fang)出(chu)，回收有物(wu)料，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)工(gong)作原理是(shi)利用高壓電(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)離(li)，氣(qi)流中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作用下與氣(qi)流分離(li)。負極(ji)由不(bu)同斷面形(xing)狀的(de)(de)金(jin)屬導(dao)(dao)線制成，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)同幾(ji)何(he)形(xing)狀的(de)(de)金(jin)屬板制成，叫(jiao)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)(chen)(chen)(chen)性質、設(she)備(bei)構造和煙氣(qi)流速等(deng)三(san)個因(yin)素的(de)(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)阻是(shi)評價導(dao)(dao)電(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有(you)直接的(de)(de)影(ying)響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒(li)難(nan)以保持在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使(shi)其重(zhong)返氣(qi)流。比電(dian)(dian)阻過高，到達(da)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)壓梯度(du)會產生局部擊穿(chuan)和放電(dian)(dian)現象。這些情況都會造成除塵(chen)(chen)(chen)(chen)(chen)效率下降。

電除塵器的基本(ben)原(yuan)理(li)是利用電力(li)捕集(ji)煙氣中的粉塵，主要包(bao)括以(yi)下四(si)個相互有關的物理(li)過程: (1) 氣體的電離。(2) 粉塵的荷(he)(he)電。(3) 荷(he)(he)電粉塵向電極移動。(4) 荷(he)(he)電粉塵的捕集(ji)。
