昌都靜電除塵器廠家

靜電除塵器的工作原(yuan)理(li)是利用高壓(ya)電(dian)(dian)場(chang)使煙氣發生電(dian)(dian)離，氣流中的粉塵(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作用下與氣流分(fen)離。負(fu)極(ji)由不同斷面形狀的金(jin)屬導(dao)線制成，叫放電(dian)(dian)電(dian)(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)(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備(bei)構(gou)造和煙(yan)氣流(liu)速(su)等三個因素的(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重(zhong)返氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度(du)會產(chan)生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)(chen)效(xiao)率下降。

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(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(qi)的(de)(de)(de)基本原(yuan)理是(shi)利用電(dian)(dian)力捕集煙氣(qi)(qi)中的(de)(de)(de)粉塵(chen)，主要包括以下四(si)個相互(hu)有關的(de)(de)(de)物(wu)理過程：（1）氣(qi)(qi)體的(de)(de)(de)電(dian)(dian)離。（2）粉塵(chen)的(de)(de)(de)荷(he)電(dian)(dian)。（3）荷(he)電(dian)(dian)粉塵(chen)向(xiang)電(dian)(dian)極移(yi)動。（4）荷(he)電(dian)(dian)粉塵(chen)的(de)(de)(de)捕集。

荷(he)電(dian)(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕集過(guo)程：在(zai)(zai)兩個曲率半徑相差較大的(de)金屬陽(yang)極(ji)(ji)和(he)陰極(ji)(ji)上，通過(guo)高壓直流電(dian)(dian)(dian)(dian)(dian)，維持一個足以使氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)的(de)電(dian)(dian)(dian)(dian)(dian)場(chang)，氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)后所產生的(de)電(dian)(dian)(dian)(dian)(dian)子：陰離(li)(li)子和(he)陽(yang)離(li)(li)子，吸(xi)附(fu)在(zai)(zai)通過(guo)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)(fen)塵(chen)(chen)上，使粉(fen)(fen)塵(chen)(chen)獲得電(dian)(dian)(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)性不同的(de)粉(fen)(fen)塵(chen)(chen)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作(zuo)用下，分(fen)(fen)別向不同極(ji)(ji)性的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)運動，沉積在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，而達到粉(fen)(fen)塵(chen)(chen)和(he)氣(qi)體(ti)(ti)分(fen)(fen)離(li)(li)的(de)目的(de)。
