Description

Technical Field

[0001] The present invention relates to the technical field of engine hydrogen production, and in particular to a random hydrogen production and blending device for an LNG engine and equipment thereof. Background Art

[0002] To alleviate energy shortages and reduce environmental pollution, finding alternative energy sources and reducing harmful emissions have become two key areas of research in internal combustion engines. Natural gas has attracted widespread attention due to its low emissions. LNG (liquefied natural gas) is an alternative fuel with advantages such as clean emissions, good economy, good anti-knock properties, high thermal efficiency, high safety, and abundant reserves. However, it also has disadvantages such as low combustion rate, low energy density, high exhaust temperature, and difficulty in storage and portability. Compared with natural gas, hydrogen has become a hot topic in energy research due to its diverse sources, renewable nature, and clean and environmentally friendly properties. Numerous studies have shown that hydrogen has faster diffusion and flame propagation speeds than other fuels, a higher octane number, a wider flammability range, and lower ignition energy. Therefore, blending hydrogen into natural gas allows the engine to operate with extremely lean mixtures, increasing the flame propagation rate, thereby improving fuel economy and reducing harmful emissions. There are two main methods for hydrogen blending in engines: direct and indirect. Indirect hydrogen blending (taking methane as an example) is produced by exhaust gas reforming in LNG engines. The process includes methane steam reforming, dry reforming, and partial oxidation reforming.

[0003] Currently, the exhaust gas and heat generated by the internal fuel of the LNG engine in existing automobiles after combustion are usually processed by a three-way catalytic converter and discharged directly from the exhaust pipe. The temperature of the automobile exhaust can reach 800-1000 degrees Celsius. Direct discharge wastes the heat contained in the exhaust gas. In addition, the direct combustion of natural gas in the engine will produce a large amount of CO, which causes fuel waste and is not conducive to environmental protection.

Bolt holes are provided on the first connecting plate 2 and the second connecting plate 3, and the first connecting plate 2 and the second connecting plate 3 are fixedly connected by bolts. The second connecting plate 3 is fixedly connected to the hydrogen reactor 4 on the side away from the first connecting plate 2. A first separation box 13 is fixedly connected to the second connecting plate 3 inside the hydrogen reactor 4. The first separation box 13 is communicated with the connecting pipe 1, and a plurality of exhaust holes 14 are opened on the box wall of the first separation box 13. In this embodiment, there are five exhaust holes 14. A second exhaust pipe 15 corresponding to the exhaust hole 14 is fixedly connected to the box wall of the first separation box 13. The other end of the second exhaust pipe 15 is fixedly connected to the wall of the first separation box 13. The end passes through the hydrogen reactor 4 along the length direction of the hydrogen reactor 4 and extends to the outside of the hydrogen reactor 4. The first separation box 13 is fixedly connected to the side away from the second connecting plate 3 with the second separation box 18.

The coplanarity of the adjacent sidewalls of the two curved plates 82 enhances the seal between the exhaust pipe and connecting pipe 1. The coordination of the multiple reaction tubes 16 with the exhaust pipe allows for more efficient utilization of exhaust heat. The hydrogen generated from the recovered heat is then introduced into the engine for co-combustion, improving fuel economy and reducing harmful emissions.

[0027] The central angle range of the arc groove 81 is 190°-220°. During the sliding process of the two arc plates 82, the ends of the two arc plates 82 always have overlapping parts. When in use, the central angle design of the arc groove 81 can keep the two arc plates 82 always have overlapping parts during the sliding process, thereby ensuring the sealing between the engine exhaust pipe and the connecting pipe 1 and improving the utilization efficiency of thermal energy.

[0028] The reaction tube 16 has straight tubes at both ends and a threaded structure in the middle that is wrapped around the outside of the corresponding second exhaust pipe 15.
