Safe and quick hydrogen dispenser, hydrogenating system, hydrogen refueling station and hydrogenating method

Abstract

The invention discloses a safe and quick hydrogen dispenser, a hydrogenating system, a hydrogen refueling station and a hydrogenating method. The hydrogen dispenser comprises a hydrogenating gun, a gas supply pipeline connecting a compressor with the hydrogenating gun, a first control unit, a pressure regulating valve arranged on the gas supply pipeline and an inner pressure acquisition module forto-be-hydrogenated equipment. The first control unit acquires a pressure signal output by the inner pressure acquisition module for to-be-hydrogenated equipment and acquires the current largest saferefueling pressure according to a preset pressure rise rate, compares the pressure signal with the current largest safe refueling pressure, and regulates the opening of the pressure regulating valve.The refueling pressure of the hydrogen dispenser is controlled within a safe range, so that the hydrogenating safety is improved. It is ensured that hydrogenation can be carried out with the allowed largest refueling pressure, so that the hydrogenating speed and rate are improved. The hydrogen charging pressure in the to-be-hydrogenated equipment can reach a required value without replacing hydrogen storage containers of different grades, so that the pressure flotation number of times of the hydrogen storage containers is reduced, and the safety is further improved.

Description

technical field [0001] The invention relates to the technical field of energy filling, in particular to a safe and fast hydrogenation machine, a hydrogenation system, a hydrogenation station and a hydrogenation method. Background technique [0002] As an efficient, clean and sustainable "carbon-free" energy, hydrogen energy has attracted widespread attention from all over the world. Due to its high efficiency and zero emissions, hydrogen fuel cell vehicle technology has become the most ideal and most likely to replace traditional The technology of automobile power system has been highly valued by governments and enterprises all over the world. At this stage, the bottleneck restricting the development of hydrogen energy utilization in the transportation field is mainly the lack of hydrogen refueling infrastructure. The hydrogen filling pressure of the hydrogen refueling station currently has two types: 35MPa and 70MPa. Among them, hydrogen refueling stations with a filling ...

AI Technical Summary

Problems solved by technology

This hydrogenation method needs to switch the connection between the vehicle-mounted gas supply system and different hydrogen storage containers multiple times, making the entire hydrogenation process time-consuming and slow, and the pressure fluctuations of the hydrogen storage container are large and the range of pressure fluctuations is large, making the hydrogen storage container The problem of fatigue failure is very prominent, and hydrogen is flammable and explosive, which has potential safety hazards
