Description

Technical Field

[0001] The present invention relates to the field of coordinated utilization of renewable energy and electricity, heat, oxygen and hydrogen, and in particular to a high-quality life system for communities in high-altitude areas that integrates electricity / heat / fuel multi-energy. Background Art

[0002] Due to the thin air in high altitude areas, the large temperature difference between day and night, and the low temperature of glacier meltwater which is often below 10 degrees Celsius all year round, life is very difficult. The basic infrastructure such as basic electricity, heating, oxygen and vegetable supply for local community residents and border outposts is poor, and it is difficult to effectively guarantee important energy and materials such as electricity, heat, oxygen and vegetables for survival.

[0003] Due to the high altitude, solar energy resources are abundant, but there are differences in light due to topographic conditions, especially in mountainous environments, where the light time and the number of hours of full photovoltaic power generation are different, which is unique. At the same time, the solar energy resources have a low match with the load demand, whether it is seasonal or daily. The heat load increases in the cold period, and solar power generation decreases during the period. On the contrary, the heat load decreases in the warm period, and solar power generation increases during the period. Whether solar energy resources can be used to solve practical problems in life such as power supply, heating, and oxygen supply throughout the year, and seasonal changes can be considered. The problem of cross-seasonal energy demand can be solved through hydrogen production, oxygen production, and biomass. At the same time, considering economy, operability, and safety, the associated energy of power supply, heating, and cross-seasonal energy storage processes can be fully utilized reasonably to meet the self-sufficiency needs of air separation oxygen supply and vegetables. This is an urgent problem to be solved. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a high-quality life system for communities in high-altitude areas that integrates electricity / heat / fuel multi-energy synergy, with photovoltaic power generation as energy, electricity storage, heating, heat storage, hydrogen production, and compressed air as loads, and is utilized through mutual coordination and cooperation between equipment based on physical characteristics and load requirements. The oxygen supply problem is solved by nitrogen protection in the compressed air sealed cabin, and the oxygen produced in the hydrogen production process assists biomass or other boilers to generate heating for life. The discharged carbon dioxide hot gas is supplied to the vegetable greenhouse, and the hydrogen storage generates electricity through fuel cells to supplement seasonal energy shortages and LED vegetable greenhouses to increase the lighting duration of vegetables. The problem solves the need for comfortable life throughout the year in high-altitude areas. At the same time, it solves the problem of mismatch between demand load and solar energy time, the problem of efficient utilization of equipment, the problem of energy supply safety, and the improvement of energy utilization, providing a comfortable life on the plateau.

[0005] The present invention uses solar power generation as energy supply and biomass as supplementary heat supply to achieve: 1. Power supply: The problem of dual-electric complementary power supply is solved through energy storage converter chemical energy storage and electrolyzer hydrogen production fuel cell. Among them, the electrolyzer hydrogen production fuel cell power supply solves the problem of cross-seasonal power supply; 2. Heating: Solve the problem of dual-heat complementary heating through photovoltaic water electrode boilers and biomass boilers, among which the biomass boiler supplements the heating to solve the problem of cross-season heating; 3. Oxygen supply: The air compressed by the air compressor is separated by nitrogen and oxygen to provide positive pressure nitrogen protection for the sealed cabin, solving the problems of equipment derating, heat dissipation, safety, etc. at high altitudes. At the same time, the nitrogen and oxygen separation technology is used to solve the problem of local living oxygen supply through air separation oxygen supply; 4. Supply fresh food: Hydrogen is produced by electrolyzers and oxygen is used to assist combustion in biomass boilers, ensuring full combustion of biomass. The high-temperature flue gas of carbon dioxide is filtered to provide the temperature of the vegetable greenhouse and the carbon dioxide gas required by the plants. The LED supplementary lighting technology is used to increase the illumination time of the plants, which cooperates with carbon dioxide gas to accelerate plant photosynthesis and promote growth. The hot water produced by the biomass boiler provides living and heating needs. If conditions permit, fish can be raised in fish ponds, and the water from fish excrement provides water for vegetable nutrition.

[0006] The principle of the present invention is: The bidirectional energy storage converter, storage battery, fuel cell and other devices are placed in a sealed cabin, and the electrolytic hydrogen production and water electrode heating and heat storage devices are placed in another relative hydrogen production cabin. The biomass boiler is placed between the vegetable greenhouse and the living residence.

[0007] (I) Compress air into the sealed cabin through an air compressor to ensure 1 atmosphere of pressure, target ventilation and heat exchange, and retain nitrogen and produce oxygen through semi-permeable membrane technology. Achieve nitrogen protection for equipment in the sealed cabin and solve the following problems at the same time: 1. One atmosphere pressure in the sealed cabin solves the problem of equipment derating; 2. The positive pressure in the sealed cabin solves the problem of dust entering from outside; 3. Nitrogen protection in the sealed cabin actively prevents fire and equipment heat exchange problems; 4. Semi-permeable membrane technology physical air separation oxygen production to meet life needs; 5. The cold water heat exchanger acts as a cooling source to exchange heat with the nitrogen in the sealed cabin, which not only regulates the temperature of the sealed cabin, but also increases the temperature of domestic water.

[0008] (ii) Through the coordination of electrolytic cell hydrogen production and water electrode boiler, adapt to the maximum power point MPPT tracking of photovoltaic power generation without inverter, realize efficient hydrogen production and heating, and ensure long-term living electricity and heating needs; 1. Electrolyzer hydrogen production and storage to meet energy needs across seasons; 2. Electrolyzer oxygen production and oxygen storage assist biomass and other boilers to generate domestic heat; 3. Fuel cell power generation provides electricity for the heating season (inter-seasonal) and produces pure water at the same time.

[0009] (III) Use bidirectional energy storage inverter to supply power and store electricity to ensure the daily electricity demand within a certain period of time.

[0010] (IV) Biomass boilers use biomass and oxygen to assist combustion, solving the problem of inter-seasonal supplementary heat sources for cold-season life and vegetable greenhouses. Based on the principle of plant photosynthesis, the carbon dioxide discharged from biomass boilers is combined with LED supplementary lighting technology to promote rapid plant growth.

[0011] Among them, carbon dioxide is the raw material of photosynthesis. Increasing the concentration of carbon dioxide can enhance photosynthesis and produce more organic matter. Therefore, appropriately increasing the concentration of carbon dioxide in the environment can improve the efficiency of photosynthesis and accelerate the growth of plants.

[0012] When the carbon dioxide content in the environment increases, it can promote photosynthesis and increase the photosynthetic rate, as shown in the following formula: CO2+H2O (light, enzyme, chloroplast) == (CH2O)n+O2; (CH2O) is carbohydrate energy; Within a certain temperature range (without harming the plants), the higher the temperature, the stronger the respiration, resulting in a shortened plant growth cycle (rapid growth) and larger plants. If nitrogen fertilizer is provided at the same time, the yield can be significantly increased, while inhibiting the plant's respiration and reducing the energy consumed by the plant.

[0013] 5. Realize the management and utilization of heat sources in high-altitude areas.

[0014] 1. The cold water exchanges heat in the sealed cabin, which not only increases the water temperature, but also absorbs the heat of the sealed cabin to dissipate heat and adjust the temperature of the sealed cabin. The water exchanged in the sealed cabin is further heated by the water electrode boiler to improve the quality of heat for daily use; 2. Due to the volatility of photovoltaic power generation, considering the efficiency and rapid response of hydrogen production, the water electrode boiler constant temperature zone is used to exchange heat with the electrolyte to ensure the optimal hydrogen production efficiency temperature of the electrolyzer, so that the electrolyzer can respond quickly to photovoltaic fluctuations and improve the efficiency of hydrogen production by electrolysis; 3. Solar power supply cannot meet the MPPT tracking requirements of the maximum power point of the bidirectional energy storage inverter, electrolyzer hydrogen production and water electrode heat storage boiler at the same time. In particular, the voltage of the electrolyzer hydrogen production is relatively fixed, and the power range of high-efficiency hydrogen production is relatively narrow, so it is difficult to adapt to the maximum power point of photovoltaic power generation. Therefore, it is necessary to cooperate with the water electrode boiler. When the photovoltaic power generation capacity is certain, the maximum power point characteristics of solar photovoltaic power generation and the linear heating characteristics of the photovoltaic water electrode heat storage boiler at 0 power start-up are fully utilized. Through the combination of the photovoltaic water electrode heat storage boiler with the bidirectional energy storage inverter or the water electrolyzer hydrogen production equipment, the optimal distribution of photovoltaic power generation energy during the photovoltaic power generation cycle and the lossless absorption of the maximum power of photovoltaic power generation are achieved. That is, the energy storage power supply of the bidirectional energy storage inverter, the hydrogen production of the water electrolyzer, the water heating of the photovoltaic water electrode heat storage boiler, and the MPPT tracking of the maximum power point of photovoltaic power generation are realized, and the maximum utilization rate of solar power generation is guaranteed.

The hydrogen production cabin 2 and the sealed insulation cabin 1 are placed near the living area, and a certain safety distance is maintained according to regulations.

[0036] The photovoltaic matrix 3 is installed around the sealed insulation cabin 1 and the hydrogen production cabin 2. The photovoltaic matrix 3 generates electricity through the photovoltaic matrix converging output power supply terminal 24, which is connected to the power input terminal 49 of the bidirectional energy storage converter through the sealed insulation cabin 1, and is connected to the positive and negative electrode timing switch 50 of the photovoltaic water electrode heat storage boiler 5 and the power input terminal 51 of the hydrogen production unit through the hydrogen production cabin 2.

[0038] As the name implies, the sealed thermal insulation cabin 1 has the characteristics of thermal insulation and sealing. Since the working efficiency of the energy storage battery 25 and the fuel cell 7 is related to the temperature, the efficient operation of the built-in equipment is ensured by adjusting the appropriate temperature. The sealed thermal insulation cabin 1 also includes a heat exchanger 27 and a pressure reducing valve 30.

The heat exchanger input water pipe 28 passes through the sealed insulation cabin 1 and is connected to the external water source, and the heat exchanger output water pipe 29 is connected to the inside of the photovoltaic water electrode heat storage boiler 5.

[0042] Furthermore, the pressure reducing valve 30 is integrated with the pressure sensor and embedded in the top of the sealed insulation cabin 1, one end of which is connected to the inside of the sealed insulation cabin 1, and the other end of which is connected to the atmosphere outside the sealed insulation cabin 1, so as to ensure that the pressure inside the sealed insulation cabin 1 is greater than the ambient pressure and to ensure a relatively constant pressure; The bidirectional energy storage converter 4 also includes an energy storage battery 25. The bidirectional energy storage converter 4 is placed in the sealed insulation cabin 1. The power input terminal 49 of the bidirectional energy storage converter is connected to the photovoltaic matrix bus output power terminal 24. The energy storage battery 25 is embedded in the bidirectional energy storage converter. The bidirectional input and output DC terminals inside the bidirectional energy storage converter 4 are connected to the positive and negative electrodes of the energy storage battery 25.

[0043] like Figure 2 and Figure 4As shown, the photovoltaic water electrode heat storage boiler 5 has the functions of water heating, heat storage, and constant temperature, and is placed in the hydrogen production cabin 2. Due to the heating principle of the photovoltaic water electrode heat storage boiler 5, the voltage and current release a large amount of heat energy through the water body with set conductivity, directly converting electrical energy into thermal energy. The heating power can be adjusted steplessly. Due to the direct heating of the water resistor, the electrical energy is 100% converted into heat with high efficiency, and there is almost no heat loss.

[0044] Based on the photovoltaic water electrode heat storage boiler heating principle, the photovoltaic water electrode heat storage boiler 5 includes a water electrode heating unit 31, a positive and negative electrode timing switch 50, a heating water body 32 and a constant temperature water body 33. The constant temperature water body 33 is located in the upper part of the photovoltaic water electrode heat storage boiler 5, and the heating water body 32 is located in the lower part of the photovoltaic water electrode heat storage boiler 5.

[0045] Furthermore, the constant temperature water body 33 and the heated water body 32 are distributed vertically and isolated from each other by the insulation material 34. The constant temperature water body lower limit temperature control valve 68 and the water body exchange pipe 64 are installed through the insulation material 34 to connect the constant temperature water body 33 with the heated water body 32. The water body heat exchange pipe 36 of the constant temperature heat exchanger 60 is placed in the constant temperature water body 33.

[0046] A constant temperature water upper limit temperature control valve 63 is embedded in the boiler wall of the constant temperature water body 33 of the photovoltaic water electrode heat storage boiler 5. One end of the constant temperature water upper limit temperature control valve 63 is connected to the constant temperature water body 33, and the other end is connected to the hot water inlet and outlet pipes 35 and the heat exchanger output water pipe 29. Among them, the other end of the hot water inlet and outlet pipes 35 is connected to the heating water body 32 of the electrode hot water boiler 5.

[0047] When the constant temperature water body 33 is lower than the lower limit temperature control valve 68 of the constant temperature water body, and the water temperature of the heated water body 32 is higher than that of the constant temperature water body 33, the lower limit temperature control valve 68 of the constant temperature water body opens to form convection with the water body exchange pipe 64, and the hot water of the heated water body 32 exchanges heat with the constant temperature water body 33 through water flow; when the temperature of the constant temperature water body 33 is higher than the upper limit temperature control valve 63 of the constant temperature water body, the upper limit temperature control valve 63 of the constant temperature water body opens to inject the relatively cold water of the heat exchanger 27 into the constant temperature water body 33 through the output water pipe 29, so as to ensure that the constant temperature of the constant temperature water body 33 is constant.

[0048] The upper limit temperature control valve 63 of the constant temperature water body is equal to the optimal upper limit temperature of the electrolytic cell 44 , and the lower limit temperature control valve 68 of the constant temperature water body is equal to the optimal lower limit temperature of the electrolytic cell 44 .

[0049] Furthermore, the positive and negative electrode timing switch 50 includes a photovoltaic access terminal 66 and a positive and negative electrode timing switch output terminal 67. The photovoltaic matrix 3 generates electricity and is connected to the photovoltaic access terminal 66 via the photovoltaic matrix converging output power supply terminal 24. The positive and negative terminals connected to the photovoltaic access terminal 66 are switched by the positive and negative electrode timing switch 50, and are connected to the movable water electrode 39 and the fixed water electrode 38 respectively by the positive and negative electrode timing switch output terminal 67.

[0050] Further, the water electrode heating unit 31 includes a movable water electrode 39, a fixed water electrode 38, a transmission unit 40 and a photovoltaic water electrode heat storage boiler controller 41. The positive and negative electrode timing switch output terminals 67 are respectively connected to the movable water electrode 39 and the fixed water electrode 38, thereby obtaining photovoltaic power generation between the movable water electrode 39 and the fixed water electrode 38.

[0051] The present invention realizes that the photovoltaic matrix 3 almost directly supplies power to the photovoltaic water electrode heat storage boiler 5. Among them, the photovoltaic water electrode heat storage boiler 5 is similar to the traditional AC water electrode boiler using a 50Hz power frequency switching time of 0.2 seconds, except that the AC power frequency constant voltage output of the traditional AC water electrode boiler is changed to directly follow the photovoltaic power generation voltage change and adopt the positive and negative electrode timing switch 50, using a lower frequency electronic or mechanical switch to switch the water electrode polarity, eliminating the photovoltaic inverter link to reduce costs and losses. In this way, while ensuring that the movable water electrode 39 and the fixed water electrode 38 are not polarized, the switching time of the positive and negative electrode timing switch 50 is reduced, and the photovoltaic power generation efficiency is improved.

[0052] Further, the transmission unit 40 also includes a driving motor 61 and a transmission screw 62. Further, the water electrode heating unit includes a movable water electrode, a fixed water electrode, a transmission unit and a controller. The movable water electrode is connected to the positive pole of the photovoltaic water electrode heat storage boiler photovoltaic power access point, and the fixed water electrode is connected to the negative pole of the photovoltaic water electrode heat storage boiler photovoltaic power access point, thereby obtaining photovoltaic power generation power between the movable water electrode and the fixed water electrode.

[0053] Based on the water electrode heating principle, the movable water electrode 39 is connected to the transmission screw 62 through a threaded buckle. When the drive motor 61 drives the transmission screw to rotate, the movable water electrode 39 is controlled to move horizontally to change the distance between the movable water electrode 39 and the fixed water electrode 38.

[0054] Therefore, under the control of the photovoltaic water electrode heat storage boiler controller 41, by changing the distance between the movable water electrode 39 and the fixed water electrode 38, the water resistance of the water body between the movable water electrode 39 and the fixed water electrode 38 is changed. The larger the relative distance between the movable water electrode 39 and the fixed water electrode 38, the greater the water resistance value, and vice versa. Therefore, the photovoltaic water electrode heat storage boiler controller 41 can determine the water resistance value by detecting the relative distance between the movable water electrode 39 and the fixed water electrode 38, and control it according to autonomous tracking or participation in the coordinated control mode of the hydrogen production unit 6. Among them, the product of the water volume corresponding to the area between the movable water electrode 39 and the fixed water electrode 38 and the resistivity is called the water resistance.

[0055] The main controller 26 reads the numerical weather forecast, monitors the photovoltaic power generation data, and the irradiation meter 53 data in real time, and communicates with the photovoltaic water electrode heat storage boiler controller 41 according to the optimal objective functions of heating, electricity storage, and hydrogen production and the control strategies of electricity storage, hydrogen storage, and heat storage, and controls the photovoltaic water electrode heat storage boiler 5 to change the distance between the movable water electrode 39 and the fixed water electrode 38, thereby changing the water resistance. With water flowing through the resistor Current The water resistance heating power is obtained Based on the principle of photovoltaic maximum power point tracking, the water resistor power is adjusted in the autonomous control mode. Equal to the maximum power point of photovoltaic Right now , thereby achieving the photovoltaic maximum power point of the photovoltaic water electrode heat storage boiler 5 Tracking, new energy is maximized.

[0056] In the coordinated control mode, the current photovoltaic maximum power point Subtract hydrogen production power Equal to the water resistance power to be adjusted Right now , thereby heating the water resistance power through the photovoltaic water electrode heat storage boiler 5 Optimal power for hydrogen production by cooperative electrolyzer , achieving the maximum power point of photovoltaic Tracking ensures the optimal power of electrolyzer hydrogen production To produce hydrogen, the photovoltaic water electrode heat storage boiler 5 is heated to ensure maximum utilization of new energy.

[0057] like Figure 2 He Ru Figure 4 The hydrogen production unit 6 includes an electrolyte tank 42, a constant temperature heat exchanger 60, an electrolyzer 44, a hydrogen storage bottle 45, and a fuel cell 7. The electrolyte tank 42 and the electrolyzer 44 are placed in the hydrogen production cabin 2, and the electrolyte tank 42 is placed around the electrolyzer 44; the hydrogen storage bottle 45 is placed around the hydrogen production cabin 2.

[0058] Furthermore, the constant temperature heat exchanger 60 adopts a bidirectional heat exchange heat pipe technology, including an electrolyte heat exchange tube 43 placed in the electrolyte tank 42 and a water heat exchange tube 36 placed in the constant temperature water body 33, and the electrolyte heat exchange tube 43 and the water heat exchange tube 36 are connected through a heat exchange pipe 48; thereby, the constant temperature water body 33 of the photovoltaic water electrode heat storage boiler is exchanged with the electrolyte constant temperature heat exchanger 43 through the water heat exchange tube 36 and the heat exchange pipe 48 to ensure the constant temperature of the electrolyte 37.

[0059] Furthermore, the fuel cell 7 is placed in the sealed and insulated cabin 2, the hydrogen storage bottle 45 is placed around the hydrogen production cabin 2, the hydrogen produced by the electrolyzer 44 is compressed into the hydrogen storage bottle 45, the hydrogen transmission pipeline 46 or the mobile hydrogen storage bottle is connected to the fuel cell hydrogen transmission inlet 47, and the fuel cell 7 generates electricity to provide supplementary electricity for high-altitude areas.

[0060] Since the electrolyzer 44 has an optimal working efficiency temperature for hydrogen production, which is generally obtained through the heat generated during the hydrogen production process of the electrolyzer 44, it takes a long time, from more than ten minutes to several tens of minutes depending on the ambient temperature. When the temperature is lost during the fluctuation of photovoltaic power generation, the response speed of hydrogen production by the electrolyzer 44 is reduced, resulting in a decrease in hydrogen production efficiency. Therefore, the bidirectional heat exchange heat pipe technology is adopted to heat the constant temperature water body 33 through the constant temperature heat exchanger 60, and the electrolyte 37 in the electrolytic tank 42 is exchanged through the water body heat exchange tube 36, the heat exchange pipe 48 and the electrolyte constant temperature heat exchange tube 43, so as to always keep the temperature of the constant temperature water body 33 and the electrolyte 37 synchronized; and maintain the temperature of the electrolyzer 44.

[0061] The vegetable greenhouse 9 includes a flue gas exhaust 12, a flue gas heat exchanger 13, a dust filter 14 and a heating radiator 65. The electrolytic oxygen storage tank 11 is connected to the biomass boiler 8 through the oxygen supply pipeline 10, and the hydrogen production associated oxygen is used to assist the combustion of the biomass boiler to promote the full combustion of biomass and reduce the generation of carbon monoxide, and provide the concentration of carbon dioxide gas; the biomass boiler 8 communicates the discharged carbon dioxide flue gas with the vegetable greenhouse 9 through the flue gas exhaust 12, the flue gas heat exchanger 13 and the dust filter 14. The hydrogen production associated oxygen is used to assist the combustion of the biomass boiler 8, and the hot flue gas is processed by smoke removal to provide heat for the vegetable greenhouse 9 and promote the growth of carbon dioxide gas for plants. At the same time, LED supplementary lights are installed to increase the illumination time of plants and promote photosynthesis of plants. Considering that the biomass boiler 8 further utilizes the temperature of the carbon dioxide flue gas discharged through the flue gas exhaust 12, further heat is exchanged with the radiator connected to the heating radiator 65 through the flue gas heat exchanger 13, and the heating temperature of the vegetable greenhouse 9 is supplemented by the heating pipeline 15.
