常州靜電除塵器廠家

靜電除塵器的(de)工作原理是利用高壓(ya)電(dian)場(chang)使(shi)煙氣發(fa)生(sheng)電(dian)離(li)，氣流中的(de)粉塵荷電(dian)在電(dian)場(chang)作用下(xia)與氣流分(fen)離(li)。負極(ji)由不同斷面形(xing)狀(zhuang)的(de)金(jin)屬(shu)導(dao)線制(zhi)成，叫放電(dian)電(dian)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)性(xing)能受(shou)粉塵(chen)(chen)(chen)性(xing)質、設備構造和(he)煙氣流速(su)等三個(ge)因素的(de)影響。粉塵(chen)(chen)(chen)的(de)比(bi)(bi)電阻是評價導(dao)電性(xing)的(de)指(zhi)標，它對除塵(chen)(chen)(chen)效率(lv)有直接的(de)影響。比(bi)(bi)電阻過(guo)低，塵(chen)(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)(chen)電極上，致使其(qi)重返氣流。比(bi)(bi)電阻過(guo)高，到(dao)達(da)集塵(chen)(chen)(chen)電極的(de)塵(chen)(chen)(chen)粒電荷不易放出，在塵(chen)(chen)(chen)層(ceng)之(zhi)間形(xing)成(cheng)電壓(ya)梯度會產(chan)生局部擊穿和(he)放電現象。這些情(qing)況都會造成(cheng)除塵(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，靜電除塵器運行電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)基本(ben)原理(li)是(shi)利用(yong)電(dian)(dian)(dian)(dian)力捕集煙氣(qi)中的(de)(de)粉(fen)塵(chen)，主要包括以下四個(ge)相互有關的(de)(de)物理(li)過程：（1）氣(qi)體的(de)(de)電(dian)(dian)(dian)(dian)離。（2）粉(fen)塵(chen)的(de)(de)荷電(dian)(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)向(xiang)電(dian)(dian)(dian)(dian)極移動。（4）荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)的(de)(de)捕集。

荷(he)電(dian)粉塵(chen)的捕集(ji)過(guo)程：在兩個曲率(lv)半徑相差較大的金屬陽極(ji)和陰極(ji)上(shang)，通(tong)過(guo)高壓直流電(dian)，維持一個足以使氣(qi)體(ti)(ti)電(dian)離的電(dian)場，氣(qi)體(ti)(ti)電(dian)離后所產(chan)生(sheng)的電(dian)子(zi)：陰離子(zi)和陽離子(zi)，吸(xi)附在通(tong)過(guo)電(dian)場的粉塵(chen)上(shang)，使粉塵(chen)獲得電(dian)荷(he)。荷(he)電(dian)極(ji)性不同(tong)的粉塵(chen)在電(dian)場力的作用下(xia)，分別(bie)向(xiang)不同(tong)極(ji)性的電(dian)極(ji)運動，沉積在電(dian)極(ji)上(shang)，而達到粉塵(chen)和氣(qi)體(ti)(ti)分離的目的。
