【摘要】：蓄热技术可以有效克服供能端与用户端在时间和空间上的不匹配问题,是提高能源利用率的重要手段之一,但是当前的蓄热技术存在蓄、放热速率较低等问题。鉴于此,本文综述了过程强化技术在蓄热中的应用。首先介绍了各类蓄热技术,包括显热蓄热、潜热蓄热以及热化学蓄热,并且从蓄热密度、蓄放热速率以及技术可行性上对各类蓄热技术的优缺点进行了比较;其后,重点回顾了代表性过程强化技术在蓄热系统中的应用,包括结构优化、材料改性以及梯级蓄热;通过分析可以看出,过程强化技术可以对蓄热过程中的传热传质进行强化,极大地提高蓄热系统的蓄放热效率。最后,本文就蓄热技术发展趋势进行了展望,蓄热系统将朝着紧凑、高效的方向发展;在未来的发展中,蓄热技术与能源互联网的结合是应用研究的重点之一。
[Abstract]:Heat storage technology can effectively overcome the problem of time and space mismatch between energy supply and user, which is one of the important means to improve energy efficiency. However, the current heat storage technology has some problems, such as storage, low heat release rate and so on. In view of this, this paper reviews the application of process strengthening technology in heat storage. This paper first introduces various kinds of heat storage technologies, including sensible heat storage, latent heat storage and thermochemical heat storage, and compares the advantages and disadvantages of various heat storage technologies in terms of heat storage density, heat storage rate and technical feasibility. The application of representative process strengthening technology in heat storage system is reviewed, including structure optimization, material modification and cascade heat storage. It can be seen that process strengthening technology can enhance heat and mass transfer during heat storage. The heat storage and exothermic efficiency of the heat storage system is greatly improved. Finally, the development trend of heat storage technology is prospected, and the heat storage system will be developed in the direction of compact and efficient. In the future, the combination of heat storage technology and energy Internet is one of the key points of application research.
