高炉炉渣处理技术及发展趋势

Treatment Technology for Blast Furnace Slag and Its Development Trend

介绍了国内高炉炉渣处理技术现状,主要包括水渣处理中的底滤法、INBA法的现状与发展。现有高炉炉渣处理技术存在着水渣处理耗水量大、污染环境、高炉炉渣余热回收率低和需要额外能源消耗等问题。离心粒化法节约水资源、无污染物排放且能有效回收炉渣余热,是高炉炉渣处理未来的发展趋势。

The present situation of domestic blast furnace(BF)slag treatment technology was introduced,mainly including the present situation and developments of bottom filtration method and INBA method in treating water slag.The existing BF slag treatment technology had some problems such as large water consumption in treating water slag,pollution of the environment,low recovery rate of waste heat from BF slag and requiring additional energy consumption.However,the centrifugal granulation method could be available,by which water resources could be saved,no pollutants were discharged and also the waste heat from slag could be effectively recovered.So it was a development trend to treat the BF slag by this method.
