【摘要】：以典型钢铁生产企业为研究对象,基于企业实际生产数据,采用物质流分析法(MFA),构建物质代谢模型.建立了能源、资源利用和污染物排放分析指标,定量描述了钢铁企业的资源能源消耗及烟粉尘排放情况.结果表明:企业层面,高炉-转炉长流程吨钢总资源消耗量为208.6 t,燃料能消耗量占能源消耗总量的93.9%,吨钢烟粉尘排放量为648.08 g,烧结和炼铁工序贡献最大,分别占总排放量的45%和36%.电炉短流程总资源消耗量为1.31 t,电能消耗量占能源消耗总量的96.7%,吨钢烟粉尘排放量67 g.工序层面,烧结、炼焦和炼铁三个主排放工序的排放量分别为222.50 g/t烧结矿、118.20 g/t焦、245.27 g/t铁.据此,提出企业节能减排和产业结构调整的方向性建议,以减少环境压力,实现钢铁企业的可持续发展.
[Abstract]:In a typical iron and steel production enterprises as the research object, the enterprise based on the practical production data, using material flow analysis (MFA), building material metabolism model. Established the energy, resource use and pollutant emission analysis indicators, quantitative description of iron and steel enterprises, resources and energy consumption and smoke dust emissions. The results show that the enterprise level of blast furnace the long process total resource consumption per ton of steel is 208.6 T, the fuel consumption accounted for 93.9% of the total energy consumption, smoke dust emissions per ton is 648.08 g, sintering and ironmaking process of the greatest contribution, accounted for 45% of the total emissions of 36%. electric furnace and short process of total resource consumption is 1.31 T, electricity consumption accounted for 96.7% of the total energy consumption, smoke dust emissions per ton of 67 g. in terms of process emissions, sintering, coking ironmaking and three main emission process is 222.50 g/t and 118.20 g/t sinter coke, respectively. According to the 245.27 g/ t In order to reduce environmental pressure and realize the sustainable development of iron and steel enterprises, the directional proposals for energy saving and emission reduction and industrial structure adjustment are put forward.
