A highly efficient and energy-saving liquid hydrogen receiving and storage system

Abstract

The present invention discloses a highly efficient and energy-saving liquid hydrogen receiving and storage system. The liquid hydrogen receiving and storage system includes a discharge arm, a liquid hydrogen storage tank, a pressurized external transfer pump and a vaporizer; the discharge arm is connected to the liquid phase inlet of the liquid hydrogen storage tank through a discharge main pipe, the liquid phase outlet of the liquid hydrogen storage tank is connected to the pressurized external transfer pump, the outlet of the pressurized external transfer pump is connected to the vaporizer, the vaporizer is connected to downstream users, and a metering and analysis device is provided on the connecting pipeline; the gas phase outlet of the liquid hydrogen storage tank is connected to the BOG main pipe. The present invention comprehensively and systematically constructs a multifunctional process flow with liquid hydrogen loading and unloading, storage, pressurized gasification, evaporated gas treatment and safe discharge. The process system can meet the safe storage, transportation and utilization of hydrogen, and can be used for the construction of liquid hydrogen receiving stations, laying the foundation for the construction of an international hydrogen energy supply chain, and effectively enriching the content of the construction of the hydrogen energy "production, storage, transportation and use" industrial chain.
