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(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)(de)凈化工(gong)作(zuo)(zuo)上(shang)(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉(chen)(chen)淀兩個系(xi)統(tong)來(lai)完(wan)成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體進(jin)(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)(qi)流能較均勻(yun)地進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大的(de)(de)(de)作(zuo)(zuo)用下，氣(qi)(qi)(qi)(qi)流速度(du)(du)迅速降低，其(qi)中有些(xie)較重的(de)(de)(de)塵(chen)(chen)粒(li)便失去速度(du)(du)而沉(chen)(chen)降下來(lai)。進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體由于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)人(ren)(ren)高(gao)壓(ya)直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體中存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子與進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)結合起來(lai)，使塵(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)場力(li)的(de)(de)(de)作(zuo)(zuo)用下趨向本設備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)采(cai)用負(fu)(fu)高(gao)壓(ya)制)和(he)陰(yin)極(ji)(ji)(ji)(負(fu)(fu)極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉(chen)(chen)積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)，通(tong)過(guo)設備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振打(da)系(xi)統(tong)的(de)(de)(de)振打(da)，使沉(chen)(chen)積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)的(de)(de)(de)粉塵(chen)(chen)振落，進(jin)(jin)(jin)人(ren)(ren)集灰斗 通(tong)過(guo)排灰裝置放出(chu)，回收有物(wu)料，被)凈化的(de)(de)(de)氣(qi)(qi)(qi)(qi)體排入(ru)大氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工作(zuo)(zuo)原(yuan)理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)(zuo)用下與氣(qi)流分離。負(fu)極(ji)由(you)不同斷面形(xing)狀(zhuang)的(de)(de)金(jin)屬導線(xian)制成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形(xing)狀(zhuang)的(de)(de)金(jin)屬板(ban)制成，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和(he)煙氣(qi)流速等三個(ge)因素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)(chen)效率有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)(li)難以保持(chi)在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒(li)(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在塵(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度(du)會(hui)(hui)產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況都會(hui)(hui)造成除塵(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器(qi)的基本原理(li)是(shi)利用電(dian)(dian)力捕(bu)集煙氣中的粉塵(chen)，主要包括以下四個相互有(you)關的物(wu)理(li)過程: (1) 氣體的電(dian)(dian)離(li)。(2) 粉塵(chen)的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵(chen)的捕(bu)集。
