A method for producing slush nitrogen, cooling method and apparatus using the manufacturing equipment and the slush nitrogen

摘要

Place the ejector which is filled with liquid nitrogen in the cryogenic container, sucking liquid nitrogen to jet or gas refrigerant liquid helium gas, or cold liquid helium of pressure higher than the container space in the vessel, the coolant Liquid nitrogen is ejected together with the refrigerant is sucked out by the fall to become a solid nitrogen atomization is cooled by the refrigerant gas in the container space slash is discharged out of the container to keep above atmospheric pressure at all times the spatial I to provide a process for the production of nitrogen. Near the temperature of liquid nitrogen, or in the method of cooling a superconducting object using materials that exhibit superconductivity at a temperature near the solid nitrogen and liquid nitrogen to co-exist, the present application is to slash nitrogen that has been held in an insulated container in addition, To provide a method of cooling a superconducting body which is characterized in that by immersing the said object, cooling is contacted with slush nitrogen to said object.
