七臺河靜電除塵器廠家

靜電除塵器的(de)工作原理是利用高壓電(dian)場使煙氣(qi)發(fa)生電(dian)離，氣(qi)流中的(de)粉塵荷電(dian)在(zai)電(dian)場作用下與氣(qi)流分離。負極(ji)由不(bu)同斷面(mian)形狀的(de)金(jin)屬導(dao)線(xian)制成(cheng)，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。靜電除塵器廠家的性能受(shou)粉塵(chen)性質(zhi)、設(she)備構造(zao)和煙氣流(liu)速(su)等三個因素的影響(xiang)。粉塵(chen)的比(bi)(bi)電(dian)(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)(dian)性的指標，它對除(chu)塵(chen)效(xiao)(xiao)率有直接的影響(xiang)。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)低(di)，塵(chen)粒難以保持在(zai)集塵(chen)電(dian)(dian)(dian)極上，致使(shi)其重返氣流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)電(dian)(dian)(dian)極的塵(chen)粒電(dian)(dian)(dian)荷不易放出(chu)，在(zai)塵(chen)層(ceng)之間形成電(dian)(dian)(dian)壓梯度會產(chan)生局部擊穿和放電(dian)(dian)(dian)現象(xiang)。這些情況都(dou)會造(zao)成除(chu)塵(chen)效(xiao)(xiao)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(ya)需保持40一(yi)75kV乃至(zhi)100kV以上。

工作原理

電(dian)(dian)除塵(chen)器的(de)基本原理是利用電(dian)(dian)力(li)捕(bu)(bu)集煙氣中的(de)粉(fen)(fen)塵(chen)，主要包(bao)括以下四(si)個(ge)相互有關的(de)物理過(guo)程：（1）氣體的(de)電(dian)(dian)離。（2）粉(fen)(fen)塵(chen)的(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)(fen)塵(chen)向電(dian)(dian)極(ji)移(yi)動。（4）荷電(dian)(dian)粉(fen)(fen)塵(chen)的(de)捕(bu)(bu)集。

荷電(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)捕集(ji)過(guo)(guo)程：在兩個(ge)曲率半徑(jing)相(xiang)差較(jiao)大的(de)金屬陽極和陰極上，通(tong)過(guo)(guo)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)，維持一個(ge)足以使氣(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)的(de)電(dian)(dian)(dian)(dian)場(chang)(chang)，氣(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)后所(suo)產生的(de)電(dian)(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和陽離(li)子(zi)，吸附(fu)在通(tong)過(guo)(guo)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)粉(fen)(fen)塵(chen)上，使粉(fen)(fen)塵(chen)獲得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極性不同(tong)的(de)粉(fen)(fen)塵(chen)在電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)作用下，分別向(xiang)不同(tong)極性的(de)電(dian)(dian)(dian)(dian)極運動，沉積在電(dian)(dian)(dian)(dian)極上，而達(da)到粉(fen)(fen)塵(chen)和氣(qi)體(ti)分離(li)的(de)目的(de)。
