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(chu)塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來收捕廢(fei)氣(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈(jing)(jing)化(hua)工作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和(he)沉(chen)淀兩個系統(tong)來完成的(de)(de)(de)，當含(han)(han)塵(chen)(chen)氣(qi)體(ti)(ti)進(jin)人(ren)氣(qi)刺叭時(shi)，含(han)(han)塵(chen)(chen)氣(qi)體(ti)(ti)受到氣(qi)流(liu)(liu)分(fen)布板(ban)以及折流(liu)(liu)板(ban)的(de)(de)(de)調整后，使(shi)(shi)氣(qi)流(liu)(liu)能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面(mian)擴大的(de)(de)(de)作用(yong)下(xia)，氣(qi)流(liu)(liu)速度迅速降低，其中(zhong)有(you)些較重(zhong)的(de)(de)(de)塵(chen)(chen)粒(li)便失去速度而沉(chen)降下(xia)來。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)(han)塵(chen)(chen)氣(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)人(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)體(ti)(ti)中(zhong)存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)(dian)(dian)子和(he)離子與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)結合(he)起(qi)來，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下(xia)趨向本設備陽極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)負高(gao)壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過設備陰(yin)陽極(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)(shi)沉(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)振落，進(jin)人(ren)集灰斗 通(tong)過排灰裝置(zhi)放出，回收有(you)物料，被(bei))凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)體(ti)(ti)排入大氣(qi)。

工作原理

靜電(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)工作原理是(shi)(shi)利(li)用高(gao)壓(ya)電(dian)場(chang)(chang)使(shi)煙氣(qi)發生電(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)(chen)荷(he)電(dian)在(zai)電(dian)場(chang)(chang)作用下與氣(qi)流(liu)分離。負(fu)極(ji)由(you)不(bu)同斷面形狀的(de)(de)金屬(shu)導線制成(cheng)，叫放電(dian)電(dian)極(ji)。正極(ji)由(you)不(bu)同幾何形狀的(de)(de)金屬(shu)板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)極(ji)。靜電(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)流(liu)速等(deng)三個因素的(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)阻(zu)是(shi)(shi)評價導電(dian)性(xing)的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有(you)直接的(de)(de)影響(xiang)。比(bi)電(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)粒(li)難(nan)以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)極(ji)上，致使(shi)其重返(fan)氣(qi)流(liu)。比(bi)電(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)荷(he)不(bu)易放出，在(zai)塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)壓(ya)梯度會產生局(ju)部擊穿和放電(dian)現象。這些情況都會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下降。

電除塵器的(de)基本原(yuan)理(li)是利用電力捕(bu)集(ji)煙氣中的(de)粉(fen)(fen)塵，主要包括(kuo)以下四個相互(hu)有(you)關的(de)物理(li)過程: (1) 氣體(ti)的(de)電離(li)。(2) 粉(fen)(fen)塵的(de)荷(he)電。(3) 荷(he)電粉(fen)(fen)塵向(xiang)電極移動(dong)。(4) 荷(he)電粉(fen)(fen)塵的(de)捕(bu)集(ji)。
