涼山靜電除塵器廠家

靜電除塵器的工作原理是利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)離，氣流中的粉塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用(yong)下(xia)與氣流分離。負極由不同斷(duan)面形(xing)狀的金屬導(dao)線制成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(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)(chen)性質、設備(bei)構(gou)造和煙氣(qi)流(liu)速等三(san)個因素(su)的(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)阻(zu)是評價(jia)導電(dian)性的(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)影響。比(bi)電(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)粒難以(yi)保持在集(ji)塵(chen)(chen)(chen)電(dian)極上，致(zhi)使其重返(fan)氣(qi)流(liu)。比(bi)電(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)(chen)電(dian)極的(de)(de)塵(chen)(chen)(chen)粒電(dian)荷(he)不易放出，在塵(chen)(chen)(chen)層之間(jian)形成(cheng)(cheng)電(dian)壓梯度(du)會產(chan)生局部擊穿和放電(dian)現象。這些情況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)效率下降(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，靜電除塵器運行電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)除塵器的(de)(de)基本(ben)原理是利(li)用電(dian)力捕集煙(yan)氣中的(de)(de)粉(fen)塵，主要(yao)包(bao)括以下四個相互有關的(de)(de)物理過程：（1）氣體(ti)的(de)(de)電(dian)離(li)。（2）粉(fen)塵的(de)(de)荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)塵向(xiang)電(dian)極移動。（4）荷(he)電(dian)粉(fen)塵的(de)(de)捕集。

荷(he)電(dian)(dian)粉(fen)(fen)塵的(de)(de)捕(bu)集過(guo)程：在(zai)(zai)(zai)兩(liang)個曲率(lv)半徑(jing)相差較大的(de)(de)金(jin)屬陽極(ji)(ji)和(he)陰極(ji)(ji)上(shang)，通過(guo)高(gao)壓(ya)直(zhi)流電(dian)(dian)，維持一個足以使(shi)氣體電(dian)(dian)離的(de)(de)電(dian)(dian)場(chang)，氣體電(dian)(dian)離后所產(chan)生的(de)(de)電(dian)(dian)子(zi)：陰離子(zi)和(he)陽離子(zi)，吸附(fu)在(zai)(zai)(zai)通過(guo)電(dian)(dian)場(chang)的(de)(de)粉(fen)(fen)塵上(shang)，使(shi)粉(fen)(fen)塵獲(huo)得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極(ji)(ji)性(xing)不同(tong)的(de)(de)粉(fen)(fen)塵在(zai)(zai)(zai)電(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下，分別(bie)向不同(tong)極(ji)(ji)性(xing)的(de)(de)電(dian)(dian)極(ji)(ji)運動，沉(chen)積在(zai)(zai)(zai)電(dian)(dian)極(ji)(ji)上(shang)，而(er)達(da)到(dao)粉(fen)(fen)塵和(he)氣體分離的(de)(de)目的(de)(de)。
