| 摘 要： | 对钢铁工业固体废弃物的组成分析表明,高炉渣占钢铁工业固体废弃物的50%左右.高炉渣是一种性能良好的硅酸盐材料,通过处理后作为生产水泥的原料,生产水泥时可节约石灰石原料45%,节约能源50%,并减少CO2排放量44%.传统的高炉渣水处理技术存在耗水量大,污染环境,产生空气、水污染,热能无法回收等缺点.拟开发新的干法处理高炉渣,不仅可以大幅度节约新水,还可以回收高炉渣的显热,另外,高炉渣粒化后可以达到传统的水处理高炉渣一样的效果.

| Abstract: | The BF slag is nearly 50% of the gross solid waste in steel industry. The BF slag is a silicate material of many applications. The BF slag is used as raw material for cement industry after treatment, with saving of 45% limestone, 50% energy consumption and reduction of 44% CO2 emission. Traditionally, the BF slag is granulated in water with air pollution, water pollution and the heat loss etc. A new method-dry granulation of BF slag could save fresh water, but also recycle the heat of slag. It can also be used in cement industry as the BF slag traditionally treated with water. |
