A hydrogen energy equipment testing system and testing method

Abstract

The invention discloses a hydrogen energy equipment testing system and testing method. The test system uses helium as the test medium, and the helium storage device supplies gas to the test system. The gas unloading cabinet, compressor, hydrogen storage cylinder group, and hydrogenation machine are in working condition, and the helium gas passes through the helium gas supply cylinder and the gas unloading cabinet. , compressor, hydrogen storage bottle group, hydrogenation machine, helium filling bottle, and finally to the helium gas supply bottle to form a gas circuit cycle to realize the test of hydrogen energy equipment. The molecular weight of helium is small, and the test result is more accurate , which is superior to nitrogen detection. Through this system, not only can gas leakage detection be realized, but also helium can be recycled. After the detection is completed, hydrogen is used to drive out the helium in the detection system, and then the magnesium-based hydrogen storage tank is used to absorb the helium. Hydrogen in the mixed gas, then recover the helium, and then use nitrogen to drive out the hydrogen in the detection system, then use the magnesium-based hydrogen storage tank to absorb the hydrogen in the mixed gas, and then recover the nitrogen to improve the detection accuracy. The cost of using helium is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy equipment, in particular to a hydrogen energy equipment testing system and testing method. Background technique [0002] With the continuous development of the hydrogen energy industry, the demand for equipment including hydrogenation machines, gas unloading cabinets, sequence control cabinets, and compressors is also increasing. Therefore, domestic hydrogen energy equipment manufacturers have sprung up. These hydrogen energy equipment Manufacturers can only conduct some simple tests in the factory, including pressure tests and power-on tests, but they cannot conduct full-condition tests and linkage tests between devices, so many problems cannot be detected in the factory. [0003] In this case, when the hydrogen energy equipment arrives at the project site for debugging, there will still be various problems such as inability to realize hydrogenation, inability to pressurize, and internal ...

Problems solved by technology

[0002] With the continuous development of the hydrogen energy industry, the demand for equipment including hydrogenation machines, gas unloading cabinets, sequence control cabinets, and compressors is also increasing. Therefore, domestic hydrogen energy equipment manufacturers have sprung up. These hydrogen energy equipment Manufacturers can only conduct some simple tests in the factory, including pressure tests and power-on tests, but they cannot perform full-condition tests and linkage tests between devices, so many problems cannot be detected in the factory

[0003] In this case, when the hydrogen energy equipment arrives at the project site for debugging, there will still be various problems such as inability to realize hydrogenation, inability to pressurize, and internal leakage of electric valves. Therefore, hydrogen energy equipment needs to be installed before installation. In the existing technology, hydrogen detection will be used for equipment assembly, but when it comes to safety issues, it is a better choice to use inert gas simulation. The molecular weight of helium is small, and the detection results are more accurate, which is better than nitrogen. Detection, because the hydrogen energy equipment is relatively large, the price of helium is expensive, and the detection cost is high
