摘要
安全放散系统是氢气罐区安全设计的重要组成部分,随着国内氢能产业规模和氢气储运规模增长,在大气量、中高压氢气的储运过程中,安全放散系统的设计尤为重要。目前国内氢气储运设施的设计标准对大规模氢气放散系统放散高度的设计存在争议,文中基于现有国内外相关标准的文献调研,总结出能够满足国内外主要设计标准放散要求的放散高度计算公式。根据放散高度计算公式、借助Flaresim5.0等工具,以西北某万吨级绿氢项目大规模氢气罐区放散系统为例进行放散高度设计计算,计算结果显示:大规模氢气放散系统开展热辐射计算校核是必要的,采用常规的5 m高放散塔进行大规模氢气放散具有威胁人身和设备安全的设计隐患,适当提高放散高度能够大幅降低对人员活动区域的热辐射强度。同时并根据计算结果提出了用于粗略校核人身设备安全的氢气放散高度便查表。
The safe vent system is an important part of the safety design of hydrogen tank area.With the increase of the scale of hydrogen energy industry and hydrogen storage and transportation at domestic,the design of the safe vent system is particularly important in the storage and transportation of large-volume and medium-high pressure hydrogen.At present,the standards of hydrogen storage and transportation facilities have no clear requirements for the design of large-scale hydrogen vent height,so it is necessary to explore the relevant design principles.Based on the literature research of domestic and international standards,this paper summarizes the calculation formula of the height of dispersion which can meet the requirements of the main domestic and international standards.Based on the formula for calculating the release height and using tools such as Flaresim5.0,the release height design calculation is carried out using the large-scale hydrogen tank area release system of a 10,000 ton green hydrogen project in Northwest China as an example.The calculation results show that it is necessary for large-scale hydrogen vent system to carry out thermal radiation calculation.The conventional 5 m vent tower for large-scale hydrogen vent has design hazards that threaten personal and equipment safety.Appropriately increasing the design height can greatly reduce the intensity of thermal radiation to personnel activity areas.Based on the calculation results,a table of hydrogen emission height for rough checking of personal or equipment safety is presented.
