十堰靜電除塵器廠家

靜電除塵器的工作原理是利(li)用(yong)高壓電(dian)場使煙氣發生電(dian)離，氣流中的粉塵(chen)荷電(dian)在電(dian)場作用(yong)下與氣流分離。負極(ji)由不同斷面形狀的金屬導線制成，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)(xing)能受(shou)粉塵(chen)(chen)(chen)性(xing)(xing)質(zhi)、設備構造(zao)和煙(yan)氣流速等三(san)個因素的(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)阻(zu)是評(ping)價導(dao)電(dian)(dian)性(xing)(xing)的(de)指標，它對除塵(chen)(chen)(chen)效(xiao)率(lv)有直接的(de)影響(xiang)。比(bi)電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以(yi)保持在集塵(chen)(chen)(chen)電(dian)(dian)極上，致使其重返(fan)氣流。比(bi)電(dian)(dian)阻(zu)過高，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)層之間形成電(dian)(dian)壓(ya)梯度會(hui)產生局部擊穿和放電(dian)(dian)現象。這些情況(kuang)都會(hui)造(zao)成除塵(chen)(chen)(chen)效(xiao)率(lv)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(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)除(chu)塵器的(de)基本原理(li)(li)是利(li)用電(dian)(dian)(dian)力捕(bu)集(ji)煙氣(qi)中(zhong)的(de)粉塵，主要包括以下四個相互有關的(de)物理(li)(li)過(guo)程：（1）氣(qi)體的(de)電(dian)(dian)(dian)離(li)。（2）粉塵的(de)荷電(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)粉塵向電(dian)(dian)(dian)極(ji)移(yi)動。（4）荷電(dian)(dian)(dian)粉塵的(de)捕(bu)集(ji)。

荷(he)電(dian)(dian)(dian)粉塵(chen)(chen)的(de)捕集過程：在(zai)兩個曲率半徑(jing)相差較大的(de)金(jin)屬(shu)陽極(ji)和陰極(ji)上，通過高(gao)壓直流電(dian)(dian)(dian)，維持一個足以(yi)使氣體(ti)電(dian)(dian)(dian)離(li)(li)的(de)電(dian)(dian)(dian)場，氣體(ti)電(dian)(dian)(dian)離(li)(li)后(hou)所產生的(de)電(dian)(dian)(dian)子：陰離(li)(li)子和陽離(li)(li)子，吸附在(zai)通過電(dian)(dian)(dian)場的(de)粉塵(chen)(chen)上，使粉塵(chen)(chen)獲得(de)電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)性(xing)不同(tong)的(de)粉塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)作用下，分別向不同(tong)極(ji)性(xing)的(de)電(dian)(dian)(dian)極(ji)運動，沉(chen)積在(zai)電(dian)(dian)(dian)極(ji)上，而達到粉塵(chen)(chen)和氣體(ti)分離(li)(li)的(de)目的(de)。

基本結構

靜(jing)電(dian)(dian)電(dian)(dian)除塵(chen)器由(you)兩大部分組成：一(yi)(yi)部分是(shi)電(dian)(dian)除塵(chen)器本體(ti)系(xi)統(tong)(tong)(tong)；另一(yi)(yi)部分是(shi)提(ti)供高(gao)(gao)壓(ya)(ya)直流電(dian)(dian)的(de)(de)供電(dian)(dian)裝置和低壓(ya)(ya)自動控制(zhi)系(xi)統(tong)(tong)(tong)。電(dian)(dian)除塵(chen)器的(de)(de)結(jie)構原理圖(tu)如圖(tu)1所示，高(gao)(gao)壓(ya)(ya)供電(dian)(dian)系(xi)統(tong)(tong)(tong)為升壓(ya)(ya)變壓(ya)(ya)器供電(dian)(dian)，除塵(chen)器集(ji)塵(chen)極(ji)接地。低壓(ya)(ya)電(dian)(dian)控制(zhi)系(xi)統(tong)(tong)(tong)用來(lai)控制(zhi)電(dian)(dian)磁振(zhen)打錘、卸灰(hui)電(dian)(dian)極(ji)、輸灰(hui)電(dian)(dian)極(ji)以及幾個部件的(de)(de)溫度。
