Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, and in particular to an integrated methanol reforming hydrogen production power generation device. Background Technology

[0002] Methanol power generation is a novel power generation method that uses methanol as fuel, generates heat through combustion, and then converts that heat into electricity using a power generation system. Its working principle is similar to that of thermal power generation, but methanol combustion produces less carbon dioxide than traditional fuels such as coal, resulting in less environmental pollution. Currently, there are two main methods for methanol power generation: direct combustion and combustion after conversion into hydrogen.

[0003] Direct combustion involves injecting methanol directly into a combustion chamber, where it mixes with air and ignites, generating high-temperature, high-pressure heat energy, which is then converted into electrical energy via a turbine. This method is simple and easy to implement, but the exhaust gases contain a certain amount of pollutants such as nitrogen oxides and sulfur dioxide. Combustion after conversion to hydrogen involves catalytically converting methanol to produce hydrogen and carbon dioxide, which are then burned in a combustion chamber, generating high-temperature, high-pressure heat energy, which is then converted into electrical energy via a turbine. This method is relatively environmentally friendly, but requires additional catalytic conversion equipment, making it more expensive.

[0004] Existing hydrogen fuel cells, whether molten carbonate fuel cells, direct methanol fuel cells, or phosphoric acid fuel cells, all suffer from excessive size and high cost. Furthermore, traditional alkaline fuel cells cause pollution after disposal. Therefore, methanol power generation has a very promising future. With technological advancements and cost reductions, methanol power generation will become a mainstream clean energy source and a key direction for my country's energy structure adjustment.

[0005] Current methanol power generation equipment operates on the principle of injecting methanol feedstock into the device, where it undergoes a catalytic reaction before entering the power generation stack to generate electricity. The methanol feedstock first enters a reforming reactor for a catalytic reaction to produce hydrogen. The hydrogen is then purified through a series of filtration processes, cooled, and enters the power generation stack to generate direct current (DC). The generated electricity can be stored in batteries, and then converted into 220V alternating current (AC) via an inverter and transformer to power the load. The equipment also features external USB, Type-C, and wireless charging ports to meet various charging needs.

[0006] However, the above products still have many defects, such as:

[0007] 1. The hydrogen production process takes 30 minutes to start up, and power generation is relatively slow;

[0008] 2. The reaction process will produce an irritating odor at the beginning, making it unsuitable for indoor use;

[0009] 3. The palladium tubes used for filtration are difficult to weld and are costly to manufacture;

[0010] 4. The operating environment requires a dry and flat surface, and the power generation speed will decrease in low-temperature environments;

[0011] 5. The maximum load power is generally no more than 3KW.

[0012] To address the aforementioned issues, our company has proposed an integrated methanol reforming hydrogen production and power generation device. Summary of the Invention
