山西靜電除塵器廠家

靜電除塵器的(de)工作原理是利用高壓電(dian)場(chang)使煙(yan)氣(qi)發(fa)生電(dian)離(li)，氣(qi)流(liu)中的(de)粉塵荷(he)電(dian)在電(dian)場(chang)作用下與氣(qi)流(liu)分離(li)。負極由不(bu)同斷面形狀(zhuang)的(de)金屬(shu)導(dao)線(xian)制成，叫放電(dian)電(dian)極。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的(de)(de)性能受粉塵(chen)(chen)性質(zhi)、設備構(gou)造和煙氣流(liu)速等三個因素的(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)(dian)性的(de)(de)指標(biao)，它(ta)對除(chu)塵(chen)(chen)效(xiao)率(lv)有直(zhi)接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重返氣流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)壓梯度(du)會產生(sheng)局部擊穿和放電(dian)(dian)(dian)現(xian)象(xiang)。這些(xie)情況(kuang)都會造成除(chu)塵(chen)(chen)效(xiao)率(lv)下降。

簡介

靜電除塵器的電源由控制箱、升壓變壓器和整流器組成。電源輸出的電壓高低對除塵效率也有很大影響。因此，靜電除塵器運行電壓需保持(chi)40一75kV乃至100kV以上(shang)。

工作原理

電(dian)除塵(chen)器(qi)的(de)基本原理是利用電(dian)力(li)捕(bu)集煙(yan)氣中的(de)粉(fen)塵(chen)，主要包括(kuo)以下四個相互有關的(de)物理過程(cheng)：（1）氣體(ti)的(de)電(dian)離。（2）粉(fen)塵(chen)的(de)荷電(dian)。（3）荷電(dian)粉(fen)塵(chen)向電(dian)極移動。（4）荷電(dian)粉(fen)塵(chen)的(de)捕(bu)集。

荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)(de)捕集過程(cheng)：在兩個曲率(lv)半(ban)徑相差較大的(de)(de)(de)(de)金屬(shu)陽(yang)極(ji)和陰(yin)極(ji)上，通過高(gao)壓(ya)直流電(dian)(dian)(dian)，維持(chi)一(yi)個足(zu)以使(shi)(shi)氣(qi)體(ti)電(dian)(dian)(dian)離的(de)(de)(de)(de)電(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)離后所(suo)產生的(de)(de)(de)(de)電(dian)(dian)(dian)子：陰(yin)離子和陽(yang)離子，吸附(fu)在通過電(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)上，使(shi)(shi)粉(fen)塵(chen)獲(huo)得電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)性(xing)不同的(de)(de)(de)(de)粉(fen)塵(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下，分(fen)別向(xiang)不同極(ji)性(xing)的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)運動，沉積在電(dian)(dian)(dian)極(ji)上，而達(da)到(dao)粉(fen)塵(chen)和氣(qi)體(ti)分(fen)離的(de)(de)(de)(de)目的(de)(de)(de)(de)。
