德陽靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原理(li)是利用高壓電場使煙氣發(fa)生電離，氣流中的(de)粉(fen)塵(chen)荷電在(zai)電場作(zuo)用下與(yu)氣流分離。負極由不同斷(duan)面形狀的(de)金屬導線制成，叫(jiao)放電電極。

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)性(xing)能受粉塵(chen)(chen)性(xing)質、設(she)備構造(zao)和煙氣(qi)流速(su)等三個因(yin)素的(de)影(ying)響。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)阻(zu)是評價(jia)導(dao)電(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)效(xiao)(xiao)率有直接的(de)影(ying)響。比電(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)粒難以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)極上，致使(shi)其(qi)重返氣(qi)流。比電(dian)(dian)(dian)阻(zu)過高(gao)，到(dao)達(da)集塵(chen)(chen)電(dian)(dian)(dian)極的(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(cheng)電(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成(cheng)除塵(chen)(chen)效(xiao)(xiao)率下降(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(xing)電壓需保持40一75kV乃(nai)至(zhi)100kV以上。

工作原理

電(dian)除塵(chen)(chen)器的(de)(de)基本原理(li)是利用電(dian)力捕集煙氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)，主(zhu)要包括以(yi)下(xia)四個相互有關的(de)(de)物理(li)過(guo)程(cheng)：（1）氣(qi)(qi)體(ti)的(de)(de)電(dian)離。（2）粉(fen)塵(chen)(chen)的(de)(de)荷電(dian)。（3）荷電(dian)粉(fen)塵(chen)(chen)向電(dian)極移動。（4）荷電(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集。

荷(he)電(dian)(dian)(dian)粉(fen)(fen)(fen)塵(chen)的(de)(de)(de)捕(bu)集(ji)過(guo)程(cheng)：在(zai)(zai)(zai)兩個曲率(lv)半(ban)徑(jing)相(xiang)差(cha)較大的(de)(de)(de)金屬陽極(ji)和(he)陰極(ji)上(shang)(shang)，通(tong)過(guo)高壓(ya)直流(liu)電(dian)(dian)(dian)，維持一個足(zu)以使(shi)氣體(ti)電(dian)(dian)(dian)離(li)的(de)(de)(de)電(dian)(dian)(dian)場，氣體(ti)電(dian)(dian)(dian)離(li)后所產生的(de)(de)(de)電(dian)(dian)(dian)子：陰離(li)子和(he)陽離(li)子，吸附(fu)在(zai)(zai)(zai)通(tong)過(guo)電(dian)(dian)(dian)場的(de)(de)(de)粉(fen)(fen)(fen)塵(chen)上(shang)(shang)，使(shi)粉(fen)(fen)(fen)塵(chen)獲得電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)性不(bu)同的(de)(de)(de)粉(fen)(fen)(fen)塵(chen)在(zai)(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下，分(fen)別向不(bu)同極(ji)性的(de)(de)(de)電(dian)(dian)(dian)極(ji)運(yun)動，沉積在(zai)(zai)(zai)電(dian)(dian)(dian)極(ji)上(shang)(shang)，而達(da)到粉(fen)(fen)(fen)塵(chen)和(he)氣體(ti)分(fen)離(li)的(de)(de)(de)目的(de)(de)(de)。
