中国长城铝业公司炭素厂有三台敞开式焙烧炉,先后上马了两套电收尘烟气净化系统,电场面积为42m~2,对焙烧炉排放的废气(主要成分为沥青焦油和粉尘)进行净化。1～2＃炉共用一套,4＃炉用一套。自投入使用以来,对焙烧炉的废气处理起到了一定的作用,产生了巨大的社会效益。但也暴露出一些不足,在此就笔者所认识到的一些问题与大家共享,希望有关专家对此发表看法,使炭素厂的烟气净化系统能更好地发挥作用。 1.系统简介(以1～2#炉电收尘为例)。正常情况下,系统的工艺流程为:
China Great Wall Aluminum Company Carbon Factory has three open-roaster, has launched two sets of electric dust flue gas purification system, the electric field area of 42m ~ 2, the roaster exhaust emissions (mainly composed of asphalt tar and dust) for Purification. 1 ~ 2 # furnace shared a set of 4 # furnace. Since it was put into use, it has played a certain role in the treatment of the exhaust gas of the roaster, resulting in huge social benefits. But also exposed some shortcomings. I hereby share with you some of the problems I have come to realize. I hope relevant experts will express their opinions on this issue so that the flue gas purification system of the carbon factory can play a better role. 1. System Introduction (1 ~ 2 # electric dust collector as an example). Under normal circumstances, the system’s process is:
