樂山靜電除塵器廠家

靜電除塵器的(de)工作原理(li)是利用高壓(ya)電(dian)場(chang)使煙氣發生電(dian)離(li)，氣流中的(de)粉(fen)塵荷電(dian)在電(dian)場(chang)作用下與氣流分離(li)。負極由不(bu)同斷面形(xing)狀的(de)金(jin)屬導(dao)線制成，叫放電(dian)電(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)性能受粉塵(chen)(chen)(chen)性質、設備構造(zao)和(he)煙(yan)氣(qi)流速等三個因(yin)素的(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性的(de)指標，它對除(chu)塵(chen)(chen)(chen)效(xiao)率有直接的(de)影(ying)響。比電(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其重返氣(qi)流。比電(dian)(dian)(dian)(dian)阻過高，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成除(chu)塵(chen)(chen)(chen)效(xiao)率下(xia)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(yun)行電(dian)壓需(xu)保(bao)持40一(yi)75kV乃至100kV以上。

工作原理

電除塵(chen)(chen)器的(de)基本(ben)原(yuan)理(li)是利用電力(li)捕集(ji)煙氣(qi)(qi)中的(de)粉(fen)(fen)塵(chen)(chen)，主要包括以下四(si)個(ge)相互有關的(de)物理(li)過(guo)程：（1）氣(qi)(qi)體的(de)電離。（2）粉(fen)(fen)塵(chen)(chen)的(de)荷電。（3）荷電粉(fen)(fen)塵(chen)(chen)向電極移動。（4）荷電粉(fen)(fen)塵(chen)(chen)的(de)捕集(ji)。

荷(he)電(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)(chen)的(de)捕(bu)集過程：在(zai)兩個曲率(lv)半徑相(xiang)差較(jiao)大的(de)金屬陽極(ji)和(he)(he)陰(yin)極(ji)上，通過高壓直(zhi)流電(dian)(dian)(dian)(dian)，維持一個足以(yi)使氣體電(dian)(dian)(dian)(dian)離的(de)電(dian)(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)(dian)離后所產生(sheng)的(de)電(dian)(dian)(dian)(dian)子：陰(yin)離子和(he)(he)陽離子，吸附在(zai)通過電(dian)(dian)(dian)(dian)場的(de)粉(fen)(fen)塵(chen)(chen)(chen)上，使粉(fen)(fen)塵(chen)(chen)(chen)獲得電(dian)(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)(dian)極(ji)性不(bu)同的(de)粉(fen)(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)場力的(de)作(zuo)用(yong)下，分別向不(bu)同極(ji)性的(de)電(dian)(dian)(dian)(dian)極(ji)運動，沉積在(zai)電(dian)(dian)(dian)(dian)極(ji)上，而達到粉(fen)(fen)塵(chen)(chen)(chen)和(he)(he)氣體分離的(de)目的(de)。

基本結構

靜(jing)電(dian)(dian)(dian)電(dian)(dian)(dian)除塵器(qi)(qi)(qi)由兩大部分(fen)(fen)組成：一部分(fen)(fen)是電(dian)(dian)(dian)除塵器(qi)(qi)(qi)本體(ti)系(xi)統(tong)；另一部分(fen)(fen)是提(ti)供高(gao)壓直(zhi)流電(dian)(dian)(dian)的(de)供電(dian)(dian)(dian)裝置和低壓自動控制(zhi)系(xi)統(tong)。電(dian)(dian)(dian)除塵器(qi)(qi)(qi)的(de)結構原理圖如圖1所示，高(gao)壓供電(dian)(dian)(dian)系(xi)統(tong)為升壓變壓器(qi)(qi)(qi)供電(dian)(dian)(dian)，除塵器(qi)(qi)(qi)集塵極(ji)接地。低壓電(dian)(dian)(dian)控制(zhi)系(xi)統(tong)用來控制(zhi)電(dian)(dian)(dian)磁振打錘、卸灰電(dian)(dian)(dian)極(ji)、輸灰電(dian)(dian)(dian)極(ji)以(yi)及幾個部件的(de)溫(wen)度。
