本文提出利用三角图示法优化合成具有温度和压力约束的氢网络。该方法将氢浓度,温度和压力约束看作氢网络匹配问题的3种关键性质,通过性质聚类转换,利用三角图示法实现氢源和氢阱的匹配。源存在域的概念的引入及表征,有助于实现源阱匹配及流量目标值的确定。不考虑增加压缩机和换热器的氢网络优化改造实例分析显示了该方法的可行性和实用性。
In this paper, we propose to optimize the synthesis of hydrogen networks with temperature and pressure constraints by the triangular diagram method. This method considers hydrogen concentration, temperature and pressure constraints as the three key properties of hydrogen network matching problem. By the nature cluster transformation, matching of hydrogen source and hydrogen trap is realized by the triangle diagram method. The introduction and characterization of the concept of source existing domain help to achieve source-well matching and flow target value determination. The example analysis of hydrogen network optimization without considering the increase of compressors and heat exchangers shows the feasibility and practicability of this method.
