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)除塵(chen)(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)凈化(hua)工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀兩(liang)個系(xi)統來(lai)完成的(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)受到(dao)氣(qi)(qi)(qi)(qi)流(liu)分(fen)布板以及(ji)折(zhe)流(liu)板的(de)(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫(heng)斷面擴(kuo)大(da)的(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降(jiang)低(di)，其(qi)中(zhong)有些(xie)較(jiao)重的(de)(de)塵(chen)(chen)(chen)(chen)粒便失去(qu)速度(du)而(er)沉(chen)降(jiang)下(xia)來(lai)。進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)(ren)(ren)高(gao)壓直(zhi)流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)子和離子，這(zhe)些(xie)電(dian)(dian)(dian)(dian)子和離子與(yu)進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用下(xia)趨向本設備(bei)陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)采用負高(gao)壓制(zhi))和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分(fen)別(bie)沉(chen)積在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備(bei)陰(yin)陽(yang)(yang)極(ji)(ji)振(zhen)打系(xi)統的(de)(de)振(zhen)打，使沉(chen)積在(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)(ren)(ren)集(ji)灰斗(dou) 通過排灰裝置放出，回(hui)收(shou)有物料，被(bei))凈化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)工作(zuo)原理(li)是利用(yong)高壓電(dian)(dian)場使(shi)煙(yan)氣發生電(dian)(dian)離，氣流中的(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作(zuo)用(yong)下(xia)與(yu)氣流分離。負(fu)極(ji)由(you)不同斷面(mian)形狀的(de)金(jin)屬導線制成(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形狀的(de)金(jin)屬板(ban)制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)性(xing)能受粉塵(chen)(chen)(chen)性(xing)質(zhi)、設備構造和(he)(he)煙(yan)氣流速等三個(ge)因素(su)的(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)阻(zu)是評(ping)價(jia)導電(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)(chen)效(xiao)率有(you)直接的(de)影(ying)響。比電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒(li)難以(yi)保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使(shi)其重(zhong)返氣流。比電(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷(he)不易放出，在塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度會(hui)產(chan)生局部擊穿和(he)(he)放電(dian)(dian)現象。這(zhe)些情況都會(hui)造成(cheng)除塵(chen)(chen)(chen)效(xiao)率下(xia)降。

電(dian)(dian)(dian)除塵(chen)器的(de)基本(ben)原理(li)是利用電(dian)(dian)(dian)力捕集煙氣(qi)(qi)中的(de)粉塵(chen)，主(zhu)要(yao)包括以下(xia)四個相互(hu)有關(guan)的(de)物(wu)理(li)過(guo)程: (1) 氣(qi)(qi)體(ti)的(de)電(dian)(dian)(dian)離。(2) 粉塵(chen)的(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)極(ji)移動。(4) 荷(he)電(dian)(dian)(dian)粉塵(chen)的(de)捕集。
