基于生命周期评价的机械装备再制造环境评价模型
|
摘要
基于生命周期评价(LCA)理论方法,运用基于过程的清单分析方法、物质流分析方法以及切削比能的能耗计算方法,设计了机械装备再制造系统边界,建立机械装备再制造环境影响评价模型。分析机械装备再制造生命周期内的原材料和能源消耗清单数据,并进行特征化和标准化处理,得到机械装备再制造生命周期内环境影响综合指标。将WD615.87型柴油发动机作为研究案例,对再制造生命周期各工艺阶段环境影响进行评价,分析再制造过程的资源、能源消耗和环境排放,提出节能减排途径。
Based on the life cycle assessment(LCA) theory, the boundary of the remanufacturing system of mechanical equipment was designed and the life cycle impact analysis model of the remanufacturing of mechanical equipment was established through the process-based life cycle inventory, the material flow analysis method and the energy consumption calculation method based on the cutting energy. The list data of raw materials and energy consumption in the remanufacturing life cycle of mechanical equipment were analyzed, and characterized as well as standardized to obtain the comprehensive index of environmental impact in the remanufacturing life cycle of mechanical equipment. WD615.87 diesel engine was taken as a case study to assess the environmental impact of each process stage in the remanufacturing life cycle. The resource, energy consumption and environmental emissions in the remanufacturing process was analyzed, and methods of energy conservation as well as emission reduction were proposed.
