Ahydrogen purifier, a hydrogen filter, a first heat exchanger group, a second heat exchanger group, a circulating hydrogen low-pressure compressor, a circulating hydrogen high-pressure compressor, a circulating hydrogen purifier, a circulating hydrogen filter, a first circulating hydrogen expansion unit, a second circulating hydrogen expansion unit, a nitrogen compressor, a liquid nitrogen air preheater, a liquid hydrogen storage tank, an ice maker system, a cold box vacuum system, a diffusing device and an electric heater are arranged in the hydrogen processing workshop. A liquid hydrogen pump, a liquid hydrogen storage tank, a liquid hydrogen truck-loading arm, a liquid hydrogen tank box, a BOGC compressor and a BOG air pre-heater are arranged in the liquid hydrogen storage workshop. Theliquid hydrogen production line is high in production efficiency and low in production cost.

Description

Technical field [0001] The invention relates to the field of liquid hydrogen production equipment, in particular to a liquid hydrogen production line. Background technique [0002] Liquid hydrogen is a liquid obtained by cooling hydrogen gas. It is a colorless, odorless, high-energy, low-temperature liquid fuel. The dual-element cryogenic liquid propellant composed of liquid hydrogen and liquid oxygen has extremely high energy and has been widely used in launch vehicles such as communication satellites, spacecraft and space shuttles. Liquid hydrogen can also form a high-energy propellant with liquid fluorine. In addition, liquid hydrogen can also be used as a fuel for new energy vehicles. Liquid hydrogen is one of the better ways to use and store hydrogen as a fuel or energy carrier. Therefore, the production of liquid hydrogen is extremely important. However, existing liquid hydrogen production lines generally have the disadvantages of low production efficiency, high energy ...
