摘要: 在碳中和、碳达峰的背景下,筛选环境友好型气体灭火剂的任务具有一定的紧迫性。目前,针对低碳链卤代烃气体,尚缺乏一种有效的临界灭火体积分数预测模型。将试验与理论分析相结合,基于因次分析法选取相关参数,以16种典型含氟气体的分子理化性质和分子结构为基础数据,采用无量纲分析法构建了临界灭火体积分数预测模型。与新型低碳链卤代烃的试验数据的对比分析说明,该模型能够有效地用于预测低碳链卤代烃气体的临界灭火体积分数,为新型卤代烃的快速筛选和研发提供一定的理论基础和重要的技术支撑。

Abstract: Under the background of carbon neutrality and carbon peak, it is urgent to screen environment-friendly gas fire extinguishing agents. There is still a lack of effective critical fire suppression concentration prediction model for low-carbon chain halogenated hydrocarbon gases. In this study, experiment and theoretical analysis are combined, and relevant parameters are selected based on dimensional analysis. Based on the molecular physicochemical properties and molecular structures of 16 typical fluorine-containing gases, this study used a dimensional analysis method to construct a critical fire suppression concentration prediction model. The comparative analysis with the experimental data of new low-carbon chain halogenated hydrocarbons shows that the model can be effectively used to predict the critical fire suppression concentration, which provides a certain theoretical basis and important technical support for the rapid screening and research and development of new halogenated hydrocarbons.
