Description

Technical Field

[0001] The present invention relates to the field of heating technology, and in particular to a zero-carbon emission multi-energy complementary thermodynamic system for airport buildings. Background Art

[0002] Solar energy refers to the thermal radiation energy of the sun, which is mainly manifested in the so-called sunlight. In modern times, it is generally used to generate electricity or provide energy for water heaters. With the decreasing non-renewable energy such as fossil fuels, solar energy as a renewable clean energy has become an important part of human energy use, and can be used as a supplement to other energy supply systems to serve mankind. Zero-carbon heating means that the heating system does not generate carbon consumption during the heating stage, such as the three-in-one heating system of solar thermal-photovoltaic power generation-air source heat pump, and the energy consumed is all renewable energy.

[0003] Moreover, the current electricity supply for airport buildings mainly comes from coal, and heating and cooling energy consumption mainly relies on electricity and natural gas (electricity consumption accounts for about 45% of total energy consumption).

[0004] At present, the photovoltaic integrated systems on airport buildings generally use solar photovoltaics as their working power source. If it is rainy, it will be difficult for the photovoltaic integrated system to generate electricity and achieve zero carbon emissions.

[0005] In addition, we know that the vents on the top of the building are usually called "exhaust vents" or "exhaust shafts". Their main function is to exhaust the indoor air to keep the indoor air circulating and fresh. It is a condition for the use of wind energy; some vents also have the function of exhausting smoke, and the high-temperature smoke they exhaust has a certain amount of heat.

Moreover, the energy consumption of the airport for cooling and heating accounts for more than half of the total energy consumption of the airport. Reducing the energy consumption level of this part will be able to better help the airport reduce energy consumption, save operating costs, and reduce carbon emissions. Therefore, it is particularly important to build a power supply method based on photovoltaic + wind power + thermal storage for energy conservation and carbon reduction in airport buildings.

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0051] Reference Figure 1-Figure 5 , a thermodynamic system for zero-carbon emission and multi-energy complementation of airport buildings, comprising:

[0052] An extended air duct section 1 located at the top of the building;

[0053] Photovoltaic panels 2, which are arranged on the top of the building;

[0054] A wind power generation component 3, which is installed on the top of the extended wind duct section 1;

[0055] An electric energy collection component 8, which is connected to the photovoltaic power generation panel 2 and the wind power generation component 3, and is used to collect and store electric energy;

[0056] The vacuum heat collecting tube assembly 4 is installed on the top of the building and is used to heat the heat storage liquid using solar energy;

[0057] A first heat storage component 5, in which a heat storage liquid is provided;

[0058] A second heat storage assembly 6, which is connected to the first heat storage assembly 5 via a connecting pipe 10;

[0059] A heat output component 11, which is used to transfer the heat stored in the second heat storage component 6 to a target device;

[0060] The wind heat exchange pipeline 7, a part of which is arranged in the extended wind duct section 1, and the other part is arranged in the first heat storage component 5, and is used to circulate the circulating medium therein under the action of the electric energy of the electric energy collection component 8, so as to heat the heat storage liquid in the first heat storage component 5;

[0061] The solar thermal energy collection pipeline 9 is used to deliver the heat storage liquid heated by the vacuum heat collection tube assembly 4 to the second heat storage assembly 6, and to recover the liquid after heat exchange in the second heat storage assembly 6 to the vacuum heat collection tube assembly 4 under the action of the electric energy of the electric energy collection assembly 8.

[0062] The above settings can be used in the following situations:

[0063] The first type is that the photovoltaic panel 2 and the wind power generation component 3 generate electricity to provide electric energy, and the vacuum heat collection tube component 4 transfers the heat of the sun to the second heat storage component 6 through the solar heat collection pipeline 9 to heat or heat exchange the target equipment that needs to be heated, and at the same time recover the liquid after the heat exchange. That is, there is no heat in the air duct

[0064] The second type is that the photovoltaic panels 2 and the wind power generation components 3 generate electricity to provide electric energy, and the vacuum heat collecting tube component 4 transfers the heat of the sun to the second heat storage component 6 through the solar heat energy collection pipeline 9, and at the same time uses the wind heat exchange pipeline 7 to first transfer the heat to the first heat storage component 5, and then to the second heat storage component 6, so as to heat or heat exchange the target equipment that needs to be heated, and at the same time recover the liquid after the heat exchange. That is, there is heat in the air duct.

[0065] The third type is that on cloudy days, the wind power generation component 3 generates electricity to provide electrical energy, and uses the wind-heat exchange pipeline 7 to first transfer the heat to the first heat storage component 5, and then to the second heat storage component 6; no matter whether it is sunny or rainy, the wind power generation component 3 is always working to generate electricity and utilize wind energy, and also utilizes and recycles the heat that is in charge, thereby utilizing the wind energy and heat energy from the building exhaust vent, making up for the defect that the photovoltaic integrated system is difficult to generate electricity in rainy weather.

[0066] The above heat is finally exchanged to the second heat storage component 6, and the power generation of light energy and wind energy is used to drive the operation of the entire system, and at the same time, solar thermal energy is further utilized. In addition, whether it is sunny or rainy, the wind power generation component 3 is always working to generate electricity and utilize wind energy, and also utilizes and recycles the heat in charge, thereby utilizing the wind energy and heat energy from the building exhaust vent, making up for the defect that the photovoltaic integrated system is difficult to generate electricity in rainy weather.

[0067] In some preferred embodiments, the structure of the extended air duct section 1 is described in detail to achieve the flexible use of hot air depending on whether the air duct has heat; specifically:

[0068] The extended air duct section 1 includes a vertical portion 100 and a U-shaped portion 101, and the connection area of ​​the vertical portion 100 is connected to both ends of the U-shaped portion 101; a rotary door sealing assembly is provided in one end below the U-shaped portion 101 and in the connection area of ​​the vertical portion 100, and a first temperature detection assembly is provided in the vertical portion 100 and below the connection area;

[0069] A portion of the air-heat exchange pipeline 7 is located in the U-shaped portion 101;

[0070] When the temperature of the extended air duct section 1 is greater than the set value, the rotary sealing door assembly of the vertical portion 100 is closed, and the rotary sealing door assembly of the U-shaped portion 101 is opened;

[0071] When the temperature of the extended air duct section 1 is lower than a set value, the rotary door sealing assembly of the vertical portion 100 is opened, and the rotary door sealing assembly of the U-shaped portion 101 is closed.

[0072] Furthermore, the rotary door sealing assembly includes a circular plate with the same inner diameter as the vertical portion 100 and the U-shaped portion 101, and a radial rod is provided on the circular plate, and the radial rod is connected to a high-temperature servo motor; the power collection assembly 8 is electrically connected to the high-temperature servo motor. Figure 4 and Figure 5 The wind power generation assembly 3 includes a rotating hood arranged on the top of the extended wind duct section 1, an axial rod is arranged inside the rotating hood; a generator is connected to the bottom of the axial rod through a speed change gear set, and the generator is fixedly connected to the inner wall of the extended wind duct section 1 through a bracket. The above structure can realize the use of wind energy for power generation at all times.

[0073] In some preferred embodiments, the wind heat exchange pipeline 7 includes a sealed circulation loop pipe, in which a coolant is arranged, and a first circulation pump 700 electrically connected to the electric energy collection component 8 is arranged on the circulation loop pipe. The first circulation pump 700 can accelerate the recovery and utilization of heat.

[0074] In some preferred embodiments, the recovery and heat transfer of the solar thermal energy collection pipeline are described in detail:

[0075] The vacuum heat collecting tube assembly 4 includes a liquid storage tank 400, and a water outlet of the liquid storage tank 400 is connected to a plurality of vacuum heat collecting tubes 401;

[0076] The connecting pipeline 10 includes a first infusion tube, on which a first solenoid valve 1000 is provided;

[0077] The solar thermal energy collection pipeline 9 includes a second liquid infusion pipe 900 and a liquid return pipe 901. The second liquid infusion pipe 900 is connected to the first liquid infusion pipe, and the connection is located below the first electromagnetic valve 1000. One end of the liquid return pipe 901 is connected to the second heat storage assembly 6, and the other end is connected to the liquid storage tank 400. The liquid return pipe 901 is provided with a second electromagnetic valve 902 close to the liquid storage tank 400, and a second circulation pump 903 close to the liquid storage tank 400.

[0078] The second circulation pump 903 , the second solenoid valve 902 and the first solenoid valve 1000 are electrically connected to the electric energy collection component 8 .

[0079] Among them, the first heat storage component 5 is provided with a second temperature detection component; the connecting pipeline 10 is used to open the first solenoid valve 1000 after the heat storage liquid in the first heat storage component 5 reaches the maximum design temperature. The second heat storage component 6 is provided with a liquid level detection sensor and a third temperature detection component; when the detection value of the third temperature detection component is less than the set value, the second solenoid valve 902 is opened and the second circulation pump 903 is started until the liquid level of the second heat storage component 6 drops to the set liquid level. The first heat storage component 5 and the second heat storage component 6 include a sealed box, the inner wall of which is covered with a thermal insulation and waterproof layer.

[0080] The above scheme is described in detail:

[0081] Normally, the liquid heated by the vacuum heat collecting tube 401 enters the second heat storage assembly 6 through the second liquid delivery pipe 900 and gradually fills up the inside thereof. At this stage, the second circulation pump 903 does not work, and the heat output assembly 11 performs heat exchange. The heat of the heat storage liquid in the second heat storage assembly 6 gradually decreases, and the temperature gradually decreases. When it decreases to the set value, the second solenoid valve 902 opens, and the second circulation pump 903 is started to return the heat storage liquid after heat exchange to the liquid storage tank 400 through the liquid return pipe 901; after recovery, the liquid heated by the vacuum heat collecting tube 401 continues to descend into the second heat storage assembly 6, and the liquid recovered by the liquid storage tank 400 is reheated. The cycle is repeated in this way.

[0082] Of course, after the first heat storage component 5 is heated, it is necessary to open the first solenoid valve 1000 thereon through the connecting pipeline 10 to send it to the second heat storage component 6. However, there is a situation that there is no heat storage liquid in the first heat storage component 5. To solve this problem, it can be automatically replenished and cooperate with the recovery operation of the solar thermal energy collection pipeline 9. The following settings are provided:

[0083] A liquid replenishing port is provided on the top of the first heat storage component 5;

[0084] A liquid infusion tube 500 is connected on the liquid return tube 901 and is located between the second solenoid valve 902 and the second circulation pump 903, and the liquid infusion tube 500 is connected to the liquid infusion port; a third solenoid valve 904 is also provided on the liquid return tube 901 and is located between the connection point between the liquid infusion tube 500 and the liquid return tube 901 and the second circulation pump 903.

[0085] That is to say, when there is no need to replenish the heat storage liquid of the first heat storage assembly 5, the second solenoid valve 902 and the third solenoid valve 904 are both closed.

[0086] When the heat storage liquid of the first heat storage assembly 5 needs to be replenished, the second solenoid valve 902 is opened, the third solenoid valve 904 is closed, and the second circulation pump 903 does not work. The heat storage liquid in the liquid storage tank 400 falls into the first heat storage assembly 5 under the action of gravity.

[0087] When recovery is required, the second solenoid valve 902 and the third solenoid valve 904 are both opened, and the second circulation pump 903 works, while overcoming the gravity of the liquid.

[0088] The various electronic devices and driving components used above all collect and store electric energy to provide electric energy through the electric energy collection component 8, which realizes the complementary operation of thermal power in various situations, does not generate carbon emissions, and uses clean energy.
