Design and Development of a New Type Cryogenic Liquid Storing Tank

In order to solve the current problems of unstable pressure during outward gas transmission from the pressure vessel containing liquid nitrogen, argon, oxygen and carbon dioxide to outside, a new type of cryogenic liquid storing tank was designed and developed in this paper. The tank main consisted of cryogenic liquid containers, pipelines, outside carburetor and external booster and valve connection. The novel cryogenic liquid storing tank could extract heat from the surrounding air and provide energy for pressurizing and vaporizing the liquid so as to make outward gas transmission stable. The practical results showed that the cryogenic liquid storing tank could be installed and used easily with good safety, durability and stable external gas pressure.
