摘要 超临界二氧化碳(Supercritical Carbon Dioxide,S-CO_(2))动力循环相较于水蒸气朗肯循环来说传热效率高、更易接入现存的各种发电系统中,是能动领域颠覆性的技术,受到全球范围内的广泛关注。本文通过专利大数据分析手段,对S-CO_(2)动力循环技术专利申请态势、地域分布、重点技术布局等相关情报进行系统性梳理、分析与归纳。研究发现,S-CO_(2)动力循环技术的专利产出整体呈现上升趋势,特别是国内专利产出呈直线增长态势;研发主体的基础创新聚焦于透平的密封、结构及其相关部件的冷却方面,对于换热器则以提升工质均匀性、设备紧凑性和降低成本为目的;我国研发主体以西安热工研究院有限公司、中国核动力研究设计院等科研单位为代表,但其海外专利布局意识有待进一步提升。 Supercritical carbon dioxide(S-CO_(2))power cycle has higher heat transfer efficiency and is easier to integrate into various existing power generation systems compared to steam Rankine cycle.It is a disruptive technology in the field of energy and has received widespread attention worldwide.This article systematically sorts out,analyzes,and summarizes the patent application situation,regional distribution,and key technology layout of supercritical carbon dioxide power cycle technology through big data analysis of patent intelligence.Research has shown that the overall patent output of supercritical carbon dioxide power cycle technology is showing an upward trend,especially with a linear growth trend in domestic patent output.The basic innovations of the R&D entity focus on the sealing,structure,and cooling of related components of the turbine.For heat exchangers,the goal is to improve the uniformity of the working fluid,equipment compactness,and cost reduction.Chinese research and development entities are represented by research institutions such as Xi’an Thermal Power Institute and China Nuclear Power Research and Design Institute,but their awareness of overseas patent layout needs to be further improved.
