Description

Technical Field

[0002] Hydrogen is a gas that does not contain carbon and does not produce CO2 after combustion. Hydrogen can be obtained through renewable energy sources such as solar energy and wind energy. It is a new energy or energy carrier. With the development of science and technology, it is widely used in engines. It has the advantages of lean combustion, low pollutant emissions and high thermal efficiency.

[0003] At present, hydrogen engines mainly use the pressure of hydrogen storage tanks to discharge hydrogen to heat exchangers for vaporization and heating to generate mixed combustible gas, which is the energy of hydrogen engines. At present, hydrogen storage tanks and heat exchangers are usually installed on the engine, and the discharge port of the hydrogen storage tank is directly connected to the heat exchanger. The engine will vibrate when it is running. After long-term use, the connection between the two is prone to misalignment and loosening, resulting in hydrogen leakage, causing safety hazards. In view of the shortcomings of the existing technology, we propose a hydrogen discharge device for hydrogen engines to solve the above problems. Utility Model Content
