Abstract

PURPOSE: To enable to drip liquefied nitrogen gas quantitatively, by preventing instantaneous vaporization of the liquefied nitrogen gas by covering the droplets of liquefied nitrogen gas to be added with cooling gas of air and thereby shielding the same from the open air.
CONSTITUTION: Nitrogen gas GN2 vaporized in an intermediate tank 2 actuates a system H for controlling the flow rate of vaporized nitrogen gas and carries cooled vaporized nitrogen gas GN2 ejected from an outlet port 70 at the lower end of a cooled-gas ejecting pipe 71 to a gas chamber 4, through control of an angle valve 72 for controlling the flow rate of vaporized gas. The cooled vaporized nitrogen gas GN2 is then carried to a vaporized-gas nozzle 73 disposed at a lower part of the gas chamber 4. Here, instantaneous vaporization of liquefied nitrogen gas LN2 to be added is prevented by shielding the droplets of liquefied nitrogen gas LN2 from the open air by convering them with cooling gas of air, with the speed of ejecting the vaporized gas GN2 being restricted in a downward direction to meet with the speed at which the liquefied nitrogen gas LN2 is dropped from an admixing nozzle 8. With such an arrangement, it is enabled to drip the liquefied nitrogen gas quantitatively.
