Problems solved by technology
[0005] At present, international automakers and related equipment manufacturers have successively announced the application of hydrogen for engine performance improvement and pollution reduction. However, the existing recombined hydrogen production equipment used in vehicles is an independent system, which requires additional loading when used, and the recombination reaction The process must provide its own heat to help the reaction proceed, and the waste heat generated by the engine cannot be effectively used for thermal energy management, resulting in low energy use efficiency

Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] refer to Figure 1 to Figure 3 , a first embodiment of the waste heat recombination hydrogen production device of the present invention is suitable for installation on an exhaust gas discharge port 100 of a vehicle (not shown in the figure), the waste heat recombination hydrogen production device includes a heating chamber 2 and a reaction chamber 3, And a conduit unit 4.
[0027] Specifically, the heating chamber 2 defines a heating chamber 21 including an air inlet 211 and an air outlet 212 respectively located on opposite sides. Install the heating chamber 2 and connect it with the exhaust gas discharge port 100 first, so that the air inlet 211 communicates with the exhaust gas discharge port 100 . In this embodiment, the air inlet 211 is in the form of a flange, which can be easily installed on an exhaust pipe 101 of the vehicle and close...

Provided is a waste heat recombination hydrogen generation device. The device is suitable to be installed on an exhaust gas discharge outlet of a vehicle, and comprises a heating cavity, a reaction cavity, and a conduit unit. The heating cavity defines a heating chamber including an air inlet and an air outlet. The air inlet is communicated with the exhaust gas discharge outlet. The reaction cavity is arranged in the heating chamber, and comprises a reaction cavity body defining a reaction space, and a catalytic unit arranged in the reaction space. The conduit unit comprises an oil inlet ductand an air-intake duct, and a product duct. One end of the oil inlet duct passes through the heating cavity and is communicated with the reaction space, and the other end is connected with an oil supply unit. The air-intake duct is coiled on the reaction cavity, wherein one end passes through the heating cavity, and the other end is communicated with the reaction space. One end of the product ductis communicated with the reaction space, and the other end passes through the heating cavity. Through installing the device on the exhaust gas discharge outlet, waste heat generated by an engine is used as a source, the oil supply unit of the vehicle provides fuel, and waste heat of the engine is effectively used to perform hydrogen generation reaction.
Description
technical field [0001] The invention relates to a hydrogen production device, in particular to a waste heat recombination hydrogen production device. Background technique [0002] Improving engine combustion efficiency and reducing emissions of particulate matter (PM) and particle number (PN) are issues that the transportation industry is currently actively improving. [0003] Among the existing technologies, hydrogen energy has been proven to be a clean energy technology with great development potential, and it is also the best energy carrier for vehicles, which can simultaneously integrate fossil energy (gasoline / diesel, compressed natural gas (CNG) / liquefied petroleum gas (liquefied petroleum gas, LPG)), biomass energy, electricity, and heat for energy conversion. [0004] Generally speaking, hydrogen production methods can be divided into high-pressure hydrogen production, liquid hydrogen production, metal hydrogen production, chemical hydrogen production, electrolyti...
