Description

Technical Field

[0001] The present invention relates to a regenerative green electricity generation device and method, belonging to the technical field of power generation. Background Art

[0002] By 2023, the proportion of China's electricity sources will be as follows: 1) Thermal power generation accounts for approximately 60-65%, mainly coal-fired, with gas and oil-fired power generation accounting for a smaller proportion; 2) Hydropower accounts for about 16-18%, and China has abundant water resources; 3) Wind power accounts for about 8-10%, indicating rapid development of wind power, especially in the northwest and coastal areas; 4) Solar power generation accounts for approximately 4-6%, indicating rapid growth in photovoltaic power generation and the gradual promotion of distributed photovoltaic power generation; 5) Nuclear power generation accounts for approximately 5-6%, indicating steady development of nuclear power, mainly in coastal areas; 6) Biomass power generation accounts for 1-2%, indicating the utilization of resources such as agricultural and forestry waste. This is a small proportion but environmentally friendly. 7) Other renewable energy sources account for less than 1%, and geothermal energy, ocean energy, etc. are in the initial stage.

[0003] Cost of thermal power generation: Each kilowatt-hour of electricity consumes 307 grams of standard coal, and the cost per kilowatt-hour is about 0.35 yuan. Adding other costs, the final on-grid electricity price remains between 0.3 yuan and 0.45 yuan.

[0004] Hydropower Cost: Hydropower primarily generates energy through the use of water droplets. The cost of hydropower remains below 0.1 yuan per kilowatt-hour, with a low of no less than 0.07 yuan. The on-grid tariff remains around 0.35 yuan.

[0005] Wind power cost: Wind drives the turbines to generate electricity. From the perspective of electricity price, the cost of wind power is about 0.2 yuan. Adding the cost of personnel and materials, the on-grid price of wind power is about 0.3 yuan, and no more than 0.35 yuan. Photovoltaic power generation cost: Photovoltaic power generation is commonly known as solar power generation, which is a power generation method that uses the sun to convert it into electricity. The advantages of photovoltaic power generation are low carbon and renewable, but its shortcomings are also very prominent. The current price of photovoltaic power generation, including construction and operation and maintenance costs, costs about 0.5 yuan per kilowatt-hour. Cost of nuclear power generation: In the entire power system, the installed capacity of nuclear power accounts for a small proportion compared with other power generation modes. Due to technical constraints, the explicit and implicit costs of nuclear power are very high. At present, the power generation cost of nuclear power plants is maintained at 0.4 yuan per kilowatt-hour. Compared with other power generation modes, its final on-grid electricity price is slightly higher.

[0006] Looking at the above-mentioned power generation modes, each mode has its advantages and disadvantages, and in essence, there is currently no power generation mode that is 100% perfect.

[0007] Therefore, when the country plans a power generation model, it will take into account the actual conditions of each region and then make comprehensive considerations. Summary of the Invention

[0017] When the temperature at the pressure reducing outlet exceeds the set temperature of 360-390℃, the pressure reducing valve will automatically open to release the pressure.

[0018] The entire process is intelligently controlled, utilizing energy recovery and regeneration, and recycling the energy itself.

The atomized water is heated to form water vapor, which expands to form airflow, circulates in the annular tube, and the airflow drives the fan wheel to rotate, thereby generating electricity. It is energy-saving, environmentally friendly and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
