興安盟靜電除塵器廠家

靜電除塵器的工作原理(li)是利用高壓(ya)電(dian)(dian)場(chang)使煙氣發生電(dian)(dian)離(li)，氣流(liu)中(zhong)的粉塵荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作用下與氣流(liu)分(fen)離(li)。負極由不同(tong)斷面形狀的金(jin)屬導(dao)線(xian)制成(cheng)，叫(jiao)放電(dian)(dian)電(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)性(xing)能受粉塵(chen)(chen)性(xing)質、設備構造(zao)和煙氣流速(su)等三個因素的(de)影響(xiang)。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)(dian)性(xing)的(de)指標，它對除(chu)塵(chen)(chen)效率(lv)有直接(jie)的(de)影響(xiang)。比電(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)極上，致(zhi)使(shi)其重返氣流。比電(dian)(dian)(dian)阻過(guo)高，到達集(ji)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)層之間形成電(dian)(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)現象。這些情況都會(hui)造(zao)成除(chu)塵(chen)(chen)效率(lv)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(xing)電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵(chen)器的(de)(de)基本原理(li)是利用電(dian)(dian)力捕(bu)集煙氣中(zhong)的(de)(de)粉塵(chen)，主要包括(kuo)以下(xia)四個相互有(you)關的(de)(de)物理(li)過(guo)程：（1）氣體的(de)(de)電(dian)(dian)離。（2）粉塵(chen)的(de)(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)(de)捕(bu)集。

荷(he)電(dian)(dian)(dian)粉塵(chen)的(de)(de)(de)(de)捕集(ji)過(guo)程(cheng)：在兩個曲率半徑相(xiang)差(cha)較大的(de)(de)(de)(de)金屬(shu)陽極(ji)(ji)(ji)(ji)和(he)(he)陰極(ji)(ji)(ji)(ji)上，通過(guo)高壓直流電(dian)(dian)(dian)，維持一個足以使(shi)氣(qi)體(ti)電(dian)(dian)(dian)離(li)的(de)(de)(de)(de)電(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)離(li)后所產(chan)生的(de)(de)(de)(de)電(dian)(dian)(dian)子：陰離(li)子和(he)(he)陽離(li)子，吸附在通過(guo)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)上，使(shi)粉塵(chen)獲得(de)電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)性不(bu)同的(de)(de)(de)(de)粉塵(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下，分(fen)別向(xiang)不(bu)同極(ji)(ji)(ji)(ji)性的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)運(yun)動(dong)，沉積(ji)在電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，而達到粉塵(chen)和(he)(he)氣(qi)體(ti)分(fen)離(li)的(de)(de)(de)(de)目的(de)(de)(de)(de)。
