【摘要】：能源与环境问题是当今社会关注的焦点问题之一。随着我国经济的快速发展和人民生活水平的不断提高,以燃煤为主的城市集中供暖成为我国建筑能耗最大的领域。一次能源不合理的利用不仅造成了惊人的能源浪费,而且还污染了环境,破坏了生态平衡。采用能源梯级利用技术,提升余热利用水平,从而提高一次能源的利用率,对我国实现节能减排目标具有非常重要的意义。本文以低品位工业余热区域供暖系统性能与优化运行为主题,选取淮安生态新城工业余热区域供暖系统为研究点,基于该系统近两年供暖运行数据,围绕余热供暖系统应用现状、运行性能、经济社会效益、系统能耗模拟分析及优化运行策略等方面,对工业余热区域供暖系统进行系统的研究,分析工业余热利用效率的影响因素,针对工业余热区域供暖系统的不同运行模型提出优化运行方案,从而实现提升能源梯级利用以及一次能源利用率的目标。本文主要研究内容如下:(1)基于国内外既有的工业余热利用研究及工程应用现状,分析低品位工业余热区域供暖的应用潜力;(2)选取淮安生态新城低品位工业余热区域供暖系统为研究点,提出工业余热供暖系统运行性能的测评方案,论述余热供暖系统的测试内容和评价方法;(3)针对淮安生态新城低品位工业余热区域供暖系统,进行系统性能的运行分析,研究分析不同工况下的供暖系统运行能效,并在此基础上探索余热利用供暖系统的节能优化运行策略;(4)针对淮安生态新城低品位工业余热区域供暖系统,对该系统进行节能评估及经济性分析,分析余热供暖系统的节能环保效果。本文采用现场实测和模拟相结合的研究方法,对淮安生态新城低品位工业余热区域供暖系统性能及优化运行进行了系统的研究,研究成果表明低品位工业余热利用可以减少煤炭消耗,提升一次能源利用率,具有较优的经济效益。本文研究成果将为今后低品位工业余热区域利用的研究以及工程应用提供理论支撑和技术方法,在建筑节能和能源等领域有着重要的意义。
[Abstract]:Energy and environment is one of the focus issues in the society.With the rapid development of Chinese economy and the improvement of people's living standard, the urban central heating, which is mainly coal burning, has become the largest area of building energy consumption in our country.The unreasonable use of primary energy not only causes an astonishing waste of energy, but also pollutes the environment and destroys the ecological balance.It is of great significance for our country to achieve the goal of energy saving and emission reduction by adopting energy cascade technology to improve the utilization level of waste heat and improve the utilization ratio of primary energy.In this paper, the performance and optimal operation of low-grade industrial waste heat region heating system are selected as the research point, based on the data of heating operation in the past two years.Based on the application status, operation performance, economic and social benefits, energy consumption simulation analysis and optimized operation strategy of the waste heat heating system, this paper makes a systematic study on the industrial waste heat region heating system.Based on the analysis of the influencing factors of industrial waste heat utilization efficiency, the optimal operation scheme is put forward for different operation models of industrial waste heat district heating system, so as to achieve the goal of improving energy cascade utilization and primary energy utilization efficiency.The main research contents of this paper are as follows: (1) based on the present situation of industrial waste heat utilization and engineering application at home and abroad,This paper analyzes the application potential of low-grade industrial waste heat region heating system. (2) selecting the low-grade industrial waste heat district heating system of Huai'an Ecological New Town as the research point, the paper puts forward a scheme for evaluating the operation performance of industrial waste heat heating system.This paper discusses the test content and evaluation method of waste heat heating system. Aiming at the low grade industrial waste heat district heating system of Huai'an Ecological New Town, the system performance is analyzed, and the energy efficiency of heating system under different working conditions is studied and analyzed.On the basis of this, the energy saving optimization operation strategy of waste heat utilization heating system is explored. Aiming at the low grade industrial waste heat district heating system of Huai'an Ecological New Town, the energy saving evaluation and economic analysis are carried out.The energy saving and environmental protection effect of waste heat heating system is analyzed.In this paper, the performance and optimal operation of the low-grade industrial waste heat district heating system in Huai'an Ecological New Town are studied systematically by the method of field measurement and simulation.The research results show that low grade industrial waste heat utilization can reduce coal consumption, improve primary energy utilization, and have better economic benefits.The research results in this paper will provide theoretical support and technical methods for the research and engineering application of low-grade industrial waste heat in the future. It is of great significance in the field of building energy conservation and energy.
