Technical Field
The invention belongs to the technical field of hydrogen replacement recovery of hydrogen bottles, and particularly relates to a hydrogen replacement recovery system and a replacement recovery method.
Background
The hydrogen storage cylinder is used for containing hydrogen and providing hydrogen for the fuel cell automobile. The domestic vehicle-mounted hydrogen storage cylinder has two specifications of 35MPa and 70MPa, and both the specifications are high-pressure gaseous hydrogen storage. For a high-pressure gaseous hydrogen storage container, the safety factor is considered, the filling gas of the original hydrogen storage cylinder is inert gas such as nitrogen, and the purity of a hydrogen medium is required by a power system such as a hydrogen fuel cell, so that the nitrogen of all the original hydrogen storage cylinders needs to be replaced before the hydrogen storage cylinder is used.
In the existing process of replacing nitrogen with hydrogen in an original hydrogen storage cylinder, a mixture of hydrogen and nitrogen is directly discharged into the atmosphere, and in a hydrogen storage system of a multi-hydrogen storage cylinder group, a large amount of hydrogen is needed in the process of replacing the nitrogen due to large capacity of the hydrogen storage cylinder, so that the waste of the hydrogen is caused by discharging the atmosphere.
