摘要:
秸秆焚烧所释放的污染物已成为我国大气污染的主要来源之一,若将秸秆制成保温型建筑材料,不仅可以减少环境污染,还可有效地降低建筑能耗. 制作了系列新型秸秆再生保温砖,采用全生命周期模型综合考虑建筑施工、运行及拆除阶段能耗,并应用傅里叶定律对南京某宾馆采用不同墙体的建筑耗能特性进行分析. 结果表明,秸秆含量的增加能显著改善秸秆砖的热工性能,但会导致其力学性能变差. 含量为4%的样砖兼具良好的热工和力学性能,采用该秸秆含量保温砖替代常用的粘土红砖和混凝土砖,在全生命周期内可分别节约21.8%和68.2%的电能消耗
Abstract:
The pollutants released by straw burning have become one of the main sources of air pollution in China. When the straw is made into thermal insulation building materials,it can not only reduce the environmental pollution caused by its incineration,but also effectively reduce the building energy consumption. Therefore,a series of new straw recycled insulation bricks are made in this paper. The energy consumption in the construction,operation and demolition stages are comprehensively considered by using the full life cycle model,and the energy consumption characteristics of a hotel in Nanjing with different walls are analyzed by employing the Fourier’s Law. It is found that the increase of straw content can significantly improve the thermal properties of straw bricks,but that it will lead to the deterioration of their mechanical properties. The sample brick with a content of 4% has the best thermal and mechanical properties. When the bricks with the straw quality content of 4% are used to replace the commonly used clay red bricks and concrete bricks,21.8% and 68.2% power consumption can be saved in the whole life cycle respectively,which suggests a remarkable energy-saving effect and a strong application prospect.
