摘　　要：利用自行设计的喷雾式天然气水合物储气实验系统,研究了喷雾强化措施下的水合物制备所形成水合物的形态特征,考察在不同初始压力和初始温度条件下水合物形成过程的压力变化特性及其对水合物生成速率和生成量的影响,并且分析和比较了间歇进气与连续进气两种不同进气方式下水合物的生成特性.实验结果表明,初始压力越高、初始温度越低,反应生成水合物的速率越快,生成的量越多;在进气方式比较方面,连续式进气生成水合物的速率比间歇式进气要快,能耗要低,因而连续式进气比间歇式进气具有更好的速率和效率.A special natural gas hydrate storage apparatus using water spraying was designed to study the gas hydrate formation characteristics enhanced by spraying water. The pressure trend, the gas hydrate formation rate and amount were observed under different initial pressures and initial temperatures in the reaction vessel. The gas hydrate formation characteristics with intermittent gas entry or continuous gas entry were compared. The experiment results show that the higher the initial pressure,or the lower the initial temperature, the quicker the hydrate forms, and the formed hydrate increases when the pressure increases or the temperature decreases. By comparison of different gas entry modes, it is found that the hydrate formation rate of continuous gas entry mode is more higher than that of intermittent gas entry mode,while the energy consume rate of continuous gas entry mode is lower than that of intermittent gas entry mode. It indicates that the hydrate formation rate and efficiency of continuous gas entry mode are better than that of intermittent gas entry mode.
