摘要
针对我国液氢加氢站热管理系统及核心换热装备相关研究不足,国外现有液氢站运行能耗偏高,难以实现大流率、低能耗运行等问题,探讨了液氢加氢站的基础运行特征,梳理了国内外热管理系统的典型工艺路线,分析了液氢加氢站热管理系统、换热装备相关的技术研究现状,并比较了不同液氢加氢站热管理系统技术特点;提出了一种新型的集汽化调温、混合接触与冷媒释冷功能三位一体的热管理系统,分析了高效热管理装备技术特征,并针对总加氢量2000 kg/d,最大加注速度7.2 kg/min的整站设计目标进行分析。研究表明:通过热管理系统及换热装备的有序用能,可至少回收38%的液氢冷能,同时减少汽化器热负荷和占地面积;通过对氢闪蒸气(BOG)的多效冷能利用,可以实现燃料电池工况下整站峰值电耗≤100 kW。相关研究可为液氢加氢站的发展和应用提供理论和技术支撑。
Given the lack of relevant research on thermal management systems and core heat exchange equipment in China,the high energy consumption,and the difficulty in realizing long-cycle and low-energy operation,the basic operation characteristics of liquid hydrogen refueling stations were first discussed,the typical process routes of various thermal management systems were sorted out,and the current technical research status and the technical characteristics were analyzed.Finally,a new thermal management system that integrates the functions of vaporization temperature regulation,mixing-heat transfer,and accumulated cooling capacity release is proposed,and the technical aspects of efficient thermal management equipment are analyzed.The total hydrogen refueling capacity of 2000 kg/d and the maximum refueling rate of 7.2 kg/min station design objectives are also examined.The study shows that through the proposed thermal management system and heat exchanger equipment for the orderly use of energy,while reducing the heat load of the air ambient vaporizer and the footprint,62%of the cold energy of liquid hydrogen can be recovered;Moreover,through the multi-effective use of cold energy of the hydrogen BOG,the fuel cell conditions of the whole station peak electric power consumption≤100 kW can be realized.It is hoped that pertinent research can offer theoretical and technical support and promote the development and application of the hydrogen energy.
