Embodiment Construction

[0046]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] Such as figure 1 As shown, this embodiment discloses a process for recovering boil-off gas of a liquid hydrogen refueling station, which can efficiently recycle and utilize the boil-off hydrogen gas (BOG) in the liquid hydrogen refueling station.

[0048] In the existing hydrogen refueling station, the conventional hydrogen refueling flow path is: after the liquid hydrogen flows out of the hydrogen storage tank, it is pressurized to a predetermined pressure by the liquid hydrogen booster pump, and then vaporized into gaseous hydrogen through a high-pressure vaporizer, which is stored in the storage tank. The hydrogen is...

Abstract

The invention discloses a hydrogen boil-off gas (BOG) recycling system and process for a liquid hydrogen refueling station and relates to the field of liquid hydrogen refueling stations. The recyclingsystem comprises a BOG treatment module and a control module, wherein by means of the BOG treatment module, recycling treatment is conducted on hydrogen boil-off gas in the liquid hydrogen refuelingstation, and by means of the control module, monitoring and control are conducted on the BOG treatment module. By means of the hydrogen boil-off gas recycling system and process, after being heated, the BOG is input into a fuel battery module for power generation; the structure is simple; and the recycling cost of the BOG is lowered.

Description

technical field [0001] The invention relates to the field of liquid hydrogen refueling stations, in particular to a hydrogen vapor recovery system and process of a liquid hydrogen refueling station. Background technique [0002] In response to the increasingly serious energy crisis and environmental problems, the development and utilization of clean energy has drawn more and more attention from all walks of life. Among them, hydrogen is known as the cleanest fuel because it only produces water after combustion, and the industry is full of expectations for its application. Hydrogen refueling stations are important basic equipment in the hydrogen energy industry chain. Due to the high storage density of liquid hydrogen and low transportation costs, hydrogen refueling stations will also use liquid hydrogen to store hydrogen. Liquid hydrogen is liquefied hydrogen gas that is liquefied at low temperature and atmospheric pressure, and its low temperature environment (about -253°C...
