LIQUEFIED HYDROGEN SUPPLY EQUIPMENT AND TANK LORRY FOR LIQUEFIED HYDROGEN SUPPLY

摘要

PROBLEM TO BE SOLVED: To provide liquefied hydrogen supply equipment and a tank lorry for liquefied hydrogen supply keeping temperature of a gas phase at an upper part of an inside of the liquefied hydrogen storage tank at set temperature by providing a bypass line bypassing a pressurized evaporator to a pressurized evaporation line and controlling flow rates of liquefied hydrogen passing through the pressurized evaporator and the bypass line respectively.SOLUTION: A first open close valve 4c is disposed at an inlet side of the pressurized evaporator 4a in the pressurized evaporation line 4 connecting the upper part and a lower part of the liquefied hydrogen storage tank 2. The bypass line 4d branching off from an inlet side of the first open close valve 4c and merging to an outlet side of the pressurized evaporator 4a is provided. A second open close valve 4e is disposed in the bypass line 4d. Valve openings of the first open close valve 4c and the second open close valve 4e are controlled so as to keep detection temperature of a temperature detector 5 detecting temperature of the gas phase of liquefied hydrogen at the upper part of the inside of the liquefied hydrogen storage tank 2. Pressure rise in the liquefied hydrogen storage tank 2 is kept small thereby at the time of liquefied hydrogen filling.
