新疆靜電除塵器廠家

靜電除塵器的(de)工作原理是利用(yong)高壓電場使煙氣(qi)(qi)發生電離，氣(qi)(qi)流中的(de)粉(fen)塵荷電在電場作用(yong)下(xia)與氣(qi)(qi)流分離。負(fu)極(ji)由不(bu)同斷(duan)面形(xing)狀的(de)金屬導線制成，叫(jiao)放電電極(ji)。

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)(chen)性質、設(she)備構造和煙氣(qi)流速(su)等三個(ge)因素的(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)比電(dian)阻(zu)是評(ping)價導電(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)效率(lv)有(you)直接的(de)(de)影響。比電(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)電(dian)極(ji)上，致使(shi)其重返氣(qi)流。比電(dian)阻(zu)過高(gao)，到(dao)達集塵(chen)(chen)(chen)電(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)荷不易放出，在塵(chen)(chen)(chen)層之間(jian)形成電(dian)壓梯度會產生(sheng)局部擊(ji)穿和放電(dian)現(xian)象(xiang)。這些(xie)情況(kuang)都(dou)會造成除(chu)塵(chen)(chen)(chen)效率(lv)下(xia)降(jiang)。

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(yun)行電壓需保持40一75kV乃至100kV以上。

工作原理

電除塵(chen)(chen)(chen)器(qi)的基本原理是利用電力(li)捕集(ji)煙氣中的粉(fen)(fen)塵(chen)(chen)(chen)，主要包括以下四個(ge)相互有(you)關的物理過程：（1）氣體的電離。（2）粉(fen)(fen)塵(chen)(chen)(chen)的荷電。（3）荷電粉(fen)(fen)塵(chen)(chen)(chen)向電極移動。（4）荷電粉(fen)(fen)塵(chen)(chen)(chen)的捕集(ji)。

荷電(dian)(dian)粉塵(chen)(chen)的捕集(ji)過(guo)程：在兩個曲(qu)率半(ban)徑相差(cha)較大的金(jin)屬陽極(ji)(ji)和陰極(ji)(ji)上，通過(guo)高壓直流電(dian)(dian)，維(wei)持(chi)一個足以使氣體電(dian)(dian)離(li)的電(dian)(dian)場，氣體電(dian)(dian)離(li)后所產生(sheng)的電(dian)(dian)子(zi)：陰離(li)子(zi)和陽離(li)子(zi)，吸附(fu)在通過(guo)電(dian)(dian)場的粉塵(chen)(chen)上，使粉塵(chen)(chen)獲得電(dian)(dian)荷。荷電(dian)(dian)極(ji)(ji)性(xing)不同的粉塵(chen)(chen)在電(dian)(dian)場力(li)的作(zuo)用(yong)下(xia)，分別向不同極(ji)(ji)性(xing)的電(dian)(dian)極(ji)(ji)運動，沉積在電(dian)(dian)極(ji)(ji)上，而達到粉塵(chen)(chen)和氣體分離(li)的目的。
