Abstract

The invention provides a system and a method capable of achieving balanced pressure-reducing rapid hydrogen filling by three storage tanks with hydrogen of any sources. The system comprises a hydrogen compression device, hydrogen storage devices and a hydrogen filling device. Hydrogen prepared by any methods is compressed via the hydrogen compression device and then is stored in the high-pressure hydrogen storage devices, and a hydrogen outlet of each hydrogen storage device is directly connected to a hydrogen dispenser or an industrial hydrogen cylinder filling system. A set of pressure-reducing balanced filling system is shared during automobile hydrogen (hydrogen for the energy purpose) filling and cylinder filling (industrial hydrogen). A pressure-reducing valve is not arranged in the system, so that pipe resistance of the system is lower, and filling rate is higher. Besides, a pre-cooling device is added to the system, so that temperature rise of a filling container is lower.

Description

technical field [0001] The invention belongs to the field of renewable, clean and environmentally friendly new energy, and provides a system and a method for rapidly filling hydrogen with balanced pressure reduction in three storage tanks. Background technique [0002] The hydrogen storage container in the currently used hydrogen filling system is usually designed so that the hydrogen is fed in from the lower end of the storage container and discharged from the upper end of the storage container. This design will increase the cost of the enterprise in practical applications, because the system is maintained before use and regularly. After that, it is necessary to purge the container and system with nitrogen. Once the large container used in the gas filling station is purged with nitrogen, it is difficult to replace the nitrogen with hydrogen. Moreover, when the hydrogen filling system fills the hydrogen container for industrial use, due to the large pressure difference, the ...
