大慶靜電除塵器廠家

靜電除塵器的工作(zuo)原理是(shi)利用(yong)(yong)高壓電場使煙氣(qi)發生電離，氣(qi)流中的粉塵荷(he)電在電場作(zuo)用(yong)(yong)下與(yu)氣(qi)流分離。負(fu)極(ji)由不同(tong)斷面(mian)形狀的金屬導線(xian)制成(cheng)，叫放電電極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構造和(he)(he)煙(yan)氣流速等三個因素(su)的影響。粉塵(chen)(chen)(chen)(chen)的比(bi)電(dian)阻(zu)(zu)是(shi)評(ping)價(jia)導電(dian)性(xing)的指(zhi)標，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有直接的影響。比(bi)電(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)電(dian)極上，致使其(qi)重返氣流。比(bi)電(dian)阻(zu)(zu)過高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)極的塵(chen)(chen)(chen)(chen)粒電(dian)荷(he)不易放(fang)(fang)出，在塵(chen)(chen)(chen)(chen)層之間形成電(dian)壓梯度會產(chan)生局部(bu)擊穿和(he)(he)放(fang)(fang)電(dian)現(xian)象(xiang)。這些(xie)情(qing)況都會造成除(chu)塵(chen)(chen)(chen)(chen)效率(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40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵(chen)器(qi)的(de)基(ji)本原理(li)是利用電(dian)(dian)力捕集(ji)煙氣(qi)中的(de)粉塵(chen)，主要包括以下四個相互有關的(de)物理(li)過程(cheng)：（1）氣(qi)體的(de)電(dian)(dian)離。（2）粉塵(chen)的(de)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(de)捕集(ji)。

荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)(chen)的捕集過(guo)程：在(zai)兩(liang)個曲率(lv)半徑相(xiang)差較大的金(jin)屬陽極(ji)(ji)和陰極(ji)(ji)上(shang)，通(tong)過(guo)高壓(ya)直流電(dian)(dian)(dian)，維持一個足(zu)以使(shi)氣體(ti)(ti)電(dian)(dian)(dian)離(li)的電(dian)(dian)(dian)場，氣體(ti)(ti)電(dian)(dian)(dian)離(li)后所產生(sheng)的電(dian)(dian)(dian)子：陰離(li)子和陽離(li)子，吸附在(zai)通(tong)過(guo)電(dian)(dian)(dian)場的粉(fen)塵(chen)(chen)(chen)上(shang)，使(shi)粉(fen)塵(chen)(chen)(chen)獲得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)(ji)性(xing)不同的粉(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的作用(yong)下，分(fen)別向不同極(ji)(ji)性(xing)的電(dian)(dian)(dian)極(ji)(ji)運動，沉積在(zai)電(dian)(dian)(dian)極(ji)(ji)上(shang)，而達到粉(fen)塵(chen)(chen)(chen)和氣體(ti)(ti)分(fen)離(li)的目的。
