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)除塵(chen)器(qi)是(shi)以靜電(dian)凈化法來(lai)收捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)，它的(de)(de)凈化工作(zuo)上要是(shi)依靠電(dian)暈極(ji)和沉淀兩個系統來(lai)完成的(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)刺叭時(shi)，含(han)塵(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)流能較均勻地進(jin)(jin)人(ren)電(dian)場(chang)。在橫(heng)斷面擴大(da)(da)(da)的(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流速(su)度(du)迅(xun)速(su)降低，其中有些較重的(de)(de)塵(chen)粒便失去速(su)度(du)而沉降下來(lai)。進(jin)(jin)人(ren)電(dian)場(chang)的(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)暈極(ji)通(tong)人(ren)高(gao)壓直流電(dian)，則(ze)在電(dian)暈極(ji)附近產生電(dian)暈現(xian)象(xiang)，使氣(qi)(qi)(qi)體(ti)電(dian)離(li)，電(dian)離(li)后(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)中存在大(da)(da)(da)量的(de)(de)電(dian)子和離(li)子，這些電(dian)子和離(li)子與進(jin)(jin)人(ren)電(dian)場(chang)的(de)(de)粉塵(chen)結合起(qi)來(lai)，使塵(chen)粒帶電(dian)，帶電(dian)塵(chen)粒在電(dian)場(chang)力的(de)(de)作(zuo)用下趨向本設備(bei)陽(yang)(yang)極(ji)(正(zheng)極(ji)、本設備(bei)采(cai)用負(fu)高(gao)壓制)和陰極(ji)(負(fu)極(ji)) ， 釋(shi)放出電(dian)子分(fen)別沉積(ji)在相應(ying)的(de)(de)電(dian)極(ji)上，通(tong)過設備(bei)陰陽(yang)(yang)極(ji)振(zhen)打系統的(de)(de)振(zhen)打，使沉積(ji)在陰陽(yang)(yang)電(dian)極(ji)上的(de)(de)粉塵(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗 通(tong)過排灰裝置放出，回收有物料，被)凈化的(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)(da)(da)氣(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的工作(zuo)原理是利用(yong)高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中的粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用(yong)下與氣(qi)(qi)流分離。負(fu)極(ji)(ji)(ji)由不同斷面形(xing)狀的金(jin)屬導(dao)線(xian)制成，叫放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同幾何形(xing)狀的金(jin)屬板(ban)制成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的性能受(shou)粉塵(chen)(chen)(chen)(chen)性質、設備構造和(he)煙氣(qi)(qi)流速等三個因素的影響。粉塵(chen)(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是評(ping)價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的指標，它對除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有直接的影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)粒(li)難以(yi)保(bao)持(chi)在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，致使(shi)其重返(fan)氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不易放出(chu)，在(zai)塵(chen)(chen)(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生局(ju)部(bu)擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情況都(dou)會造成除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除(chu)塵器(qi)的(de)基本原理(li)是利用(yong)電(dian)(dian)力捕集煙氣中的(de)粉塵，主要(yao)包(bao)括以下四個相(xiang)互有關(guan)的(de)物理(li)過程: (1) 氣體(ti)的(de)電(dian)(dian)離。(2) 粉塵的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵向電(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)粉塵的(de)捕集。
