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)(dian)(dian)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈(jing)化工作(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉(chen)淀兩個系統(tong)來完成的(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進人氣(qi)(qi)(qi)刺(ci)叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)分布板(ban)以(yi)及折流(liu)板(ban)的(de)(de)(de)(de)(de)(de)調整后，使(shi)(shi)(shi)氣(qi)(qi)(qi)流(liu)能(neng)較均勻地(di)進人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下(xia)(xia)，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低，其(qi)中有(you)些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒便失(shi)去速(su)度而(er)沉(chen)降下(xia)(xia)來。進人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在(zai)(zai)大量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與(yu)進人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)結合起來，使(shi)(shi)(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下(xia)(xia)趨向(xiang)本(ben)設(she)備(bei)陽極(ji)(正極(ji)、本(ben)設(she)備(bei)采用(yong)(yong)負高壓制)和(he)陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)(zai)相應(ying)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通過(guo)設(she)備(bei)陰陽極(ji)振(zhen)打(da)系統(tong)的(de)(de)(de)(de)(de)(de)振(zhen)打(da)，使(shi)(shi)(shi)沉(chen)積在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落(luo)，進人集灰(hui)斗 通過(guo)排(pai)灰(hui)裝置放出，回收有(you)物(wu)料(liao)，被)凈(jing)化的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)(qi)。

工(gong)作(zuo)原理(li)

靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)(de)粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)流(liu)分離。負極(ji)(ji)由不同斷面形(xing)(xing)狀的(de)(de)(de)金屬導線(xian)制成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾(ji)何形(xing)(xing)狀的(de)(de)(de)金屬板(ban)制成(cheng)(cheng)，叫集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)性能受粉(fen)塵(chen)性質、設備構(gou)造和(he)煙氣(qi)流(liu)速等三個因素的(de)(de)(de)影響。粉(fen)塵(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對除塵(chen)效(xiao)率(lv)有(you)直接的(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)低，塵(chen)粒難(nan)以保持在集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)高，到(dao)達集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在塵(chen)層之間形(xing)(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局(ju)部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會造成(cheng)(cheng)除塵(chen)效(xiao)率(lv)下降。

電(dian)(dian)除(chu)塵(chen)器的基本原理是(shi)利用(yong)電(dian)(dian)力捕(bu)集煙氣中的粉(fen)塵(chen)，主要包括(kuo)以(yi)下四個相互(hu)有關的物理過(guo)程: (1) 氣體的電(dian)(dian)離(li)。(2) 粉(fen)塵(chen)的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)的捕(bu)集。
