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)(dian)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)凈(jing)(jing)化法來收捕廢氣(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈(jing)(jing)化工作(zuo)上(shang)要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉(chen)淀兩個系統來完成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)刺(ci)叭時，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)(liu)(liu)分(fen)布板(ban)以及折(zhe)流(liu)(liu)(liu)板(ban)的(de)(de)(de)調整后，使氣(qi)(qi)流(liu)(liu)(liu)能較(jiao)均勻(yun)地進(jin)人(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫(heng)斷面擴大(da)(da)的(de)(de)(de)作(zuo)用下，氣(qi)(qi)流(liu)(liu)(liu)速(su)度迅速(su)降低，其中有些較(jiao)重的(de)(de)(de)塵(chen)(chen)粒(li)便失去速(su)度而沉(chen)降下來。進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)高壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)體(ti)中存在(zai)大(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離(li)子(zi)(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離(li)子(zi)(zi)(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)結合起來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用下趨向本設(she)(she)備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)(she)備(bei)采用負(fu)高壓制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分(fen)別沉(chen)積在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過(guo)(guo)設(she)(she)備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)振(zhen)打(da)，使沉(chen)積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗 通過(guo)(guo)排灰裝置放出，回(hui)收有物料，被)凈(jing)(jing)化的(de)(de)(de)氣(qi)(qi)體(ti)排入大(da)(da)氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)(de)工作原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下(xia)與(yu)氣(qi)流(liu)分離。負(fu)極(ji)(ji)由(you)不同斷面形狀的(de)(de)(de)(de)(de)金(jin)屬導線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形狀的(de)(de)(de)(de)(de)金(jin)屬板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)(de)性能受(shou)粉(fen)(fen)塵(chen)(chen)(chen)性質、設備構造(zao)和煙氣(qi)流(liu)速等(deng)三個(ge)因素的(de)(de)(de)(de)(de)影響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評價(jia)導電(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)高(gao)，到(dao)達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易(yi)放出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生局(ju)部擊穿和放電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)效率(lv)下(xia)降。

電(dian)(dian)除塵器的基本原理是(shi)利用(yong)電(dian)(dian)力捕(bu)集煙氣中的粉塵，主(zhu)要包括(kuo)以下(xia)四個(ge)相互有關的物理過程: (1) 氣體的電(dian)(dian)離。(2) 粉塵的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向(xiang)電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵的捕(bu)集。
