Gas filling system and gas filling method of gas storage bottle

Abstract

The invention discloses a gas filling system of a gas storage bottle. The gas filling system comprises a gas storage tank body, a three-way valve, a manually adjusted pressure reducer, a filter, a gas storage bottle and a cooler, wherein three connecting openings of the three-way valve are respectively connected with the gas storage tank body, the manually adjusted pressure reducer and the filter; the filter is connected with the gas storage bottle; the manually adjusted reducing device is connected with a vacuum pump device; a pressure meter is arranged at an outlet of the vacuum pump device. The gas filling system of the gas storage bottle can be used for filling a hydrogen storage bottle, and is also suitable for filling a natural gas bottle; after gas in the gas storage bottle is used up, the gas storage bottle can be repeatedly filled and used.

Description

Technical field [0001] The present invention relates to an energy supply system. Specifically, the supply system is mainly aimed at a gas storage cylinder charging system, especially a hydrogen storage cylinder charging system and a charging method. Background technique [0002] The storage and transportation of hydrogen has always been a big issue. There are currently two main storage methods for hydrogen: high-pressure hydrogen storage and hydrogen storage alloys. It is well known that both high-pressure tanks and hydrogen storage alloys have the characteristics of heavy weight and difficult transportation. In addition, hydrogen storage alloys are very expensive and difficult to popularize. [0003] Domestic control methods for hydrogen refueling stations often require frequent start and stop of equipment, resulting in low efficiency of equipment. In addition, when using high-pressure hydrogen cylinders to inflate, a one-way valve is used to control the direction of gas flow to...

Problems solved by technology

As we all know, both high-pressure tanks and hydrogen storage alloys have the characteristics of heavy weight and difficult transportation. In addition, hydrogen storage alloys are very expensive and difficult to popularize.

[0003] Domestic control methods for hydrogen refueling stations often require frequent startup and shutdown of equipment, resulting in low equipment efficiency

In addition, when using high-pressure hydrogen cylinders to inflate, a one-way valve is used to control the direction of gas flow to prevent the gas from flowing backwards. At the same time, it causes waste of the remaining gas in the hydrogen cylinder and increases the possibility of direct contact between the hydrogen medium and the operator.

Furthermore, the inflation process is an exothermic process, if the heat is not removed in time, the system will be dangerous
