关于液氧长期贮存方法的探索研究
|
摘要
为了探索液氧长期贮存的方法,建立了液氧在小型敞口容器、中型密闭容器和主冷凝蒸发器三种不同容器中的蒸损实验模型,分析了液氧中碳氢化合物的积聚机理,并设想了一种液氧、液氮联合贮存的方案,以低温氮气冷凝回流液氧贮罐中挥发出的气氧,通过降低液氧的蒸损率来控制碳氢化合物的积聚,以实现液氧长期贮存的目的。
Aimed at exploring the method of long-term storage of liquid oxygen,it establishes three experimental models:small-sized opened container,middle-sized closed container,and condensing-evaporator,which could test the evaporation loss rate. Based on analyzing the accumulation mechanism of hydrocarbon in the liquid oxygen,it designs a storage model by combining with liquid oxygen and liquid nitrogen. It utilizes the cryogenic gaseous nitrogen condensate the evaporative oxygen in the storage container,which could largely decrease the evaporation loss and secondly control the accumulation of the hydrocarbon in liquid oxygen,as a result of realizing the method of long-term storage of liquid oxygen.
