Embodiment 1

[0060] Embodiment 1 Sealing performance test

[0061] After checking that all parts are connected, turn on the vacuum pump and vacuum gauge connected to the pipeline assembly panel. The vacuum pump is connected to the hydrogen storage bed through the third pipeline, and the hydrogen storage bed is evacuated by the vacuum pump for 30~60 minutes until the value of the vacuum gauge is 10. -8 Pa, turn off the vacuum pump. Observe whether the pressure rises, if it rises or the system pressure does not draw 10 -8 Pa, indicating that there is a leak in the hydrogen storage bed or the valve is not connected properly. It is necessary to reinstall the hydrogen storage bed or repair the leakage of the hydrogen storage bed. If the pressure does not rise, it means that there is no leakage, and the sealing performance of the hydrogen storage bed is good.

Embodiment 2

[0062] Example 2 Hydrogen storage bed purging

[0063] After confirming that the sealing performance of the hydrogen storage bed is good, purge the hydrogen storage bed.

[0064] If the hydrogen storage material in the hydrogen storage bed is in the state of absorbing hydrogen, the first gas source is connected to the pipeline collection panel through the first pipeline, and the hydrogen storage bed is connected to the pipeline collection panel through the third pipeline to charge the hydrogen storage bed. 2~3 bar hydrogen, after the inflation is completed, close the first pipeline, and turn on the vacuum pump at the same time, vacuumize the hydrogen storage bed for 10~15min, after the vacuum is completed, turn off the vacuum pump. Repeat 2 to 3 times to complete the purging of the hydrogen storage bed.

[0065] If the hydrogen storage bed is in the state of dehydrogenation, raise the temperature of the hydrogen storage bed to 110°C through the temperature controller, and at ...

Embodiment 3

[0066] Example 3 Hydrogen absorption test

[0067] If the hydrogen absorption pressure required by the hydrogen storage bed is less than 0.25 MPa, hydrogen can be absorbed from the metering tank, and the hydrogen absorption kinetic performance and hydrogen absorption capacity of the hydrogen storage bed can be tested by recording the pressure of the metering tank over time. First connect the first gas source to the pipeline assembly panel through the first pipeline, then connect the metering tank to the pipeline assembly panel through the fourth pipeline, and fill the metering tank with 0.1~0.25 MPa hydrogen through the first gas source. Then close the first pipeline and the fourth pipeline, and after the metering tank is stabilized, connect the metering tank to the hydrogen storage bed through the fifth pipeline, so that the hydrogen storage bed starts to absorb hydrogen, record the pressure value of the metering tank over time, and obtain the The hydrogen absorption curve of...

Abstract

The invention discloses a comprehensive hydrogen storage bed performance testing device and a determination method using the same, aiming at solving the problems that the current studies are mainly used for testing a hydrogen storage material and the determination on the storage and supply performances of the hydrogen storage bed is rarely reported. The comprehensive hydrogen storage bed performance testing device comprises a first gas source, a second gas source, a pipeline integration panel and the like; the device can comprehensively test the performances of the hydrogen storage bed and accurately determine the performances of the hydrogen storage bed, so as to provide accurate results for the hydrogen gas storage and the hydrogen gas supply of the hydrogen storage bed. The testing device and the determination method can measure the hydrogen absorption and desorption capacity, the hydrogen absorption and desorption speed and the absorption and desorption hydrogen circulating performance of the hydrogen storage bed, the temperature rising rate and the cooling rate of the bed body, and the hydrogen isotope effect of the hydrogen storage bed, so as to realize recovery of He-3 in the hydrogen storage bed, provide high hydrogen pressure and high vacuum atmosphere to the hydrogen storage bed, provide the required mixed gas and realize gas circulation inside the testing device; and overvoltage protection is carried out in a hydrogen desorption process of the hydrogen storage bed and the performances of the hydrogen storage bed can be determined through data acquisition.

Description

technical field [0001] The invention relates to the field of hydrogen storage, in particular to a comprehensive test device for the performance of a hydrogen storage bed and a measurement method using the same. The invention can test various properties of the hydrogen storage bed, wherein the hydrogen is protium, deuterium, and tritium. Background technique [0002] Energy and the environment are important issues of concern in today's world. Obtaining a clean and efficient renewable energy has become the guarantee for the sustainable development of human society. Deuterium-tritium nuclear fusion energy has the advantages of unlimited resources, huge energy release, and no environmental pollution, so it is considered to be the main way for human beings to obtain energy in the future. Hydrogen energy is the energy generated by the reaction of hydrogen and oxygen. As a renewable energy source with a wide range of sources, clean and efficient, it has shown great prospects in the...
