摘要
搭建了SF_(6)及其分解产物超临界液化微型试验装置,试验装置可同时满足高温高压和拉曼光谱检测要求,研究了SF_(6)及其主要分解组分(SO_(2)、H_(2)S和CO)分别与氮气构成的二元体系中,各组分体积分数、体系压力变化对混合气体超临界液化影响。结果表明:所有二元气体体系中液化温度随体系压力和二者混合比例变化而变化。具体而言,液化温度随体系压力的增加而增加,升温速率逐渐降低;SF_(6)、SO_(2)和CO在体系中的体积分数越高,液化所需温度越高,而H2S的液化温度与其在N2中的混合比例成反比。研究结果为相关气体检测设备的研发提供了理论依据。
This paper establishes a miniature experimental setup for supercritical liquefaction of SF_(6) and its decomposition products,and this apparatus can simultaneously meet the requirements for high-temperature/highpressure(HTHP)conditions and Raman spectroscopy detection.The paper also makes studies on the effects of the volume fractions of each component and the system pressure variations on the supercritical liquefaction of the mixed gases in the binary systems that SF_(6) and its main decomposition components(SF_(6),H_(2)S and CO)respectively form with nitrogen.The results indicate that the liquefaction temperature in all binary gas systems varies with both system pressure and the mixing ratio of the components.Specifically,the liquefaction temperature increases with the rise of system pressure,and the heating rate gradually decreases;the higher the volume fractions of SF_(6),SO_(2) and CO in the system,the higher temperatures required for liquefaction,while the liquefaction temperature of H2S shows an inverse proportionality to its mixing ratio in N₂.The research results provides a theoretical basis for the research and development of the related gas detection equipment.
