濮陽靜電除塵器廠家

靜電除塵器的工作(zuo)原理(li)是利用高壓電場使煙氣發生電離，氣流(liu)中的粉(fen)塵荷電在電場作(zuo)用下與氣流(liu)分(fen)離。負極(ji)由不同斷面形狀的金屬導線制成，叫放電電極(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)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣流速等三個因素的(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)阻是評價導電(dian)(dian)性(xing)的(de)指標，它對(dui)除塵(chen)(chen)(chen)(chen)效率(lv)有直(zhi)接的(de)影(ying)響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難(nan)以保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣流。比電(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放(fang)出(chu)，在(zai)塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓(ya)梯度(du)會產生(sheng)局部擊(ji)穿和放(fang)電(dian)(dian)現象。這些情(qing)況都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率(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，靜電除塵器運行電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵器(qi)的基本原理(li)是(shi)利用電(dian)(dian)力捕(bu)集煙氣(qi)(qi)中(zhong)的粉(fen)塵，主要包括(kuo)以(yi)下四個相(xiang)互有關的物理(li)過(guo)程：（1）氣(qi)(qi)體的電(dian)(dian)離。（2）粉(fen)塵的荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)塵向電(dian)(dian)極(ji)移動。（4）荷電(dian)(dian)粉(fen)塵的捕(bu)集。

荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)(chen)的(de)捕集過(guo)程(cheng)：在兩個曲率(lv)半徑相差較大的(de)金屬陽極(ji)(ji)和陰極(ji)(ji)上，通(tong)過(guo)高(gao)壓直流電(dian)(dian)(dian)，維(wei)持一(yi)個足以使氣體(ti)電(dian)(dian)(dian)離(li)的(de)電(dian)(dian)(dian)場，氣體(ti)電(dian)(dian)(dian)離(li)后所(suo)產生的(de)電(dian)(dian)(dian)子：陰離(li)子和陽離(li)子，吸(xi)附(fu)在通(tong)過(guo)電(dian)(dian)(dian)場的(de)粉(fen)塵(chen)(chen)(chen)上，使粉(fen)塵(chen)(chen)(chen)獲得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)(ji)性不(bu)同的(de)粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)作用(yong)下，分別向不(bu)同極(ji)(ji)性的(de)電(dian)(dian)(dian)極(ji)(ji)運動，沉積(ji)在電(dian)(dian)(dian)極(ji)(ji)上，而(er)達(da)到(dao)粉(fen)塵(chen)(chen)(chen)和氣體(ti)分離(li)的(de)目的(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除塵(chen)(chen)器(qi)由兩(liang)大部(bu)分組成：一部(bu)分是(shi)電(dian)(dian)除塵(chen)(chen)器(qi)本體系(xi)(xi)統(tong)(tong)；另(ling)一部(bu)分是(shi)提供高(gao)壓(ya)直流(liu)電(dian)(dian)的供電(dian)(dian)裝置和低壓(ya)自動控(kong)制系(xi)(xi)統(tong)(tong)。電(dian)(dian)除塵(chen)(chen)器(qi)的結構原理圖(tu)如圖(tu)1所示，高(gao)壓(ya)供電(dian)(dian)系(xi)(xi)統(tong)(tong)為升壓(ya)變壓(ya)器(qi)供電(dian)(dian)，除塵(chen)(chen)器(qi)集塵(chen)(chen)極(ji)接(jie)地。低壓(ya)電(dian)(dian)控(kong)制系(xi)(xi)統(tong)(tong)用來控(kong)制電(dian)(dian)磁(ci)振打錘、卸(xie)灰(hui)(hui)電(dian)(dian)極(ji)、輸灰(hui)(hui)電(dian)(dian)極(ji)以及幾個(ge)部(bu)件的溫度。
