Description

Technical Field

[0001] This invention relates to the field of reforming hydrogen production and power generation technology, and more particularly to a reforming hydrogen production and power generation device. Background Technology

[0002] Among the various methanol-to-hydrogen processes currently available, methanol reforming is considered the most feasible. By reforming methanol and water to produce hydrogen, which is then fed into a fuel cell stack for power generation, hydrogen can be produced and used immediately. This technology reduces issues related to hydrogen transportation, storage, refueling, and safety, thus lowering the cost of hydrogen use. Methanol reforming fuel cell technology can utilize existing energy infrastructure and support systems, offering greater safety assurance. Furthermore, methanol reforming hydrogen production technology can be applied to areas such as onboard range extenders and mobile emergency power supplies.

[0003] In existing methanol-to-hydrogen power generation devices, the operating temperature of the fuel cell stack is typically between 50 and 100 degrees Celsius. Too low a temperature leads to a decrease in the reaction rate of the fuel cell stack, while too high a temperature causes corrosion and damage to the stack materials. Therefore, this paper proposes a methanol-to-hydrogen power generation device with an integrated design that facilitates temperature control. Summary of the Invention

[0004] This invention is a reforming hydrogen production power generation device proposed to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reforming hydrogen production power generation device, comprising a main frame, a reformer fixedly installed inside the main frame, a pure methanol storage tank fixedly installed on one side of the main frame, a pumping assembly fixedly connected to the output end of the pure methanol storage tank, a combustion furnace fixedly connected to the output end of the pumping assembly, a fixed pipe fixedly passing through the circulating medium output end of the combustion furnace, a fuel cell stack fixedly passing through the other end of the fixed pipe, an output assembly fixedly passing through the bottom of the fuel cell stack, a cooling assembly fixedly passing through the other end of the output assembly, the cooling assembly being connected to the combustion furnace, and a methanol-water storage tank fixedly installed on one side of the inner bottom of the main frame.

[0006] Furthermore, the bottom of the pure methanol storage tank is fixedly connected to the pure methanol input end of the reformer, and the methanol-water storage tank is fixedly connected to the methanol-water input end of the reformer.

[0007] Furthermore, an air pump is fixedly connected to the air input end of the reformer.

[0008] Furthermore, the pumping assembly includes a pure methanol pump, which is fixedly installed on one side of the outer surface of the combustion furnace. The output end of the pure methanol pump is fixedly connected to the methanol input end of the combustion furnace, and a methanol pipe is fixedly connected between the input end of the pure methanol pump and the pure methanol storage tank.

[0009] Furthermore, the top of the fuel cell stack has a cooling medium inlet, and the cooling medium outlet is fixedly connected to the fixed pipe. The bottom of the fuel cell stack has a cooling medium outlet, and the hydrogen-rich gas inlet of the fuel cell stack and the hydrogen-rich gas outlet of the reformer are fixedly connected.

[0010] Furthermore, the output component includes a first connecting pipe, which is fixedly connected to the cooling medium output port. A second connecting pipe is fixedly connected to the bottom of the first connecting pipe. A temperature sensor is fixedly connected to one side of the outer surface of the second connecting pipe, and the detection end of the temperature sensor extends through the outer wall of the second connecting pipe into the interior.

[0011] Furthermore, a circulation pump is fixedly connected to the other end of the second connecting pipe, and a third connecting pipe is fixedly connected to the output end of the circulation pump.

[0012] Furthermore, the cooling assembly includes a radiator, which is fixedly connected to the main frame. The input end of the radiator is fixedly connected to the third connecting pipe. The output end of the radiator and the input end of the combustion furnace are both fixedly connected by a return pipe. Three cooling fans are fixedly installed on one side of the outer surface of the radiator.

[0013] The beneficial effects of this invention are:

[0014] In use, this reforming hydrogen power generation device comprises a pure methanol storage tank, a combustion furnace, a fixed pipe, a fuel cell stack, a cooling assembly, an output assembly, and a pumping assembly. Using pure methanol as fuel in conjunction with a circulating cooling medium, the stack temperature can be increased. Once the stack temperature reaches the set point, heating of the circulating cooling medium is no longer necessary; instead, the cooling assembly dissipates heat and controls the temperature, ensuring effective control of the stack temperature and guaranteeing its performance. Furthermore, the integrated design minimizes footprint and facilitates layout. Attached Figure Description

The bottom of the pure methanol storage tank 4 is fixedly connected to the pure methanol input end of the reformer 2, and the methanol-water storage tank 16 is fixedly connected to the methanol-water input end of the reformer 2.

[0023] The output end of the pure methanol storage tank 4 is fixedly connected to a pumping assembly, and the output end of the pumping assembly is fixedly connected to a combustion furnace 6. The pumping assembly includes a pure methanol pump 13, and the pure methanol pump 13 is fixedly installed on one side of the outer surface of the combustion furnace 6. The output end of the pure methanol pump 13 is fixedly connected to the methanol input end of the combustion furnace 6. A methanol pipe 17 is fixedly connected between the input end of the pure methanol pump 13 and the pure methanol storage tank 4, which can transport the pure methanol in the pure methanol storage tank 4 to the combustion furnace 6.

[0024] A fixed pipe 11 is fixedly connected to the output end of the circulating medium of the combustion furnace 6. An electric stack 12 is fixedly connected to the other end of the fixed pipe 11. An output component is fixedly connected to the bottom of the electric stack 12. A cooling component is fixedly connected to the other end of the output component. The cooling component is connected to the combustion furnace 6. The output component includes a first connecting pipe 14, which is fixedly connected to the cooling medium output port. A second connecting pipe is fixedly connected to the bottom of the first connecting pipe 14. A temperature sensor 15 is fixedly connected to one side of the outer surface of the second connecting pipe, and the detection end of the temperature sensor 15 passes through the second connecting pipe. The outer wall of the connecting pipe extends into the interior. The other end of the second connecting pipe is fixedly connected to the circulation pump 8. The output end of the circulation pump 8 is fixedly connected to the third connecting pipe 9. The cooling assembly includes a radiator 5, and the radiator 5 is fixedly connected to the main frame 1. The input end of the radiator 5 is fixedly connected to the third connecting pipe 9. The output end of the radiator 5 and the input end of the combustion furnace 6 are both fixedly connected to a return pipe 7. Three cooling fans 10 are fixedly installed on one side of the outer surface of the radiator 5. The cooling fans 10 can increase the air circulation speed and improve the heat dissipation effect of the radiator 5.

[0025] The top of the fuel cell stack 12 is provided with a cooling medium inlet, and the cooling medium outlet is fixedly connected to the fixed pipe 11.

[0026] Working principle: During operation, the pure methanol pump 13 operates, and the pure methanol pump 13 delivers methanol from the pure methanol storage tank 4 to the combustion furnace 6 through the methanol pipe 17. The combustion furnace 6 is ignited, and the heat generated heats the circulating cooling medium. The heated cooling medium enters the fuel cell stack 12 through the fixed pipe 11 to heat the fuel cell stack 12. Then, it enters the second connecting pipe through the first connecting pipe 14. The circulating cooling medium then enters the circulating pump 8 through the second connecting pipe, and then enters the radiator 5 through the third connecting pipe 9. Finally, it enters the combustion furnace 6 through the return pipe 7. When the temperature sensor 15 detects that the temperature of the circulating cooling medium in the second connecting pipe has reached the set value, the pure methanol pump 13 stops operating, the combustion furnace 6 stops heating the circulating cooling medium, and the cooling fan 10 starts operating. When the circulating cooling medium passes through the radiator 5, the radiator 5 and the cooling fan 10 work together to dissipate heat and cool it. The cooled circulating cooling medium enters the combustion furnace 6 through the return pipe 7, and then enters the fuel cell stack 12 through the fixed pipe 11 to cool the fuel cell stack 12.
