Description

Technical Field

[0001] The utility model relates to a planting greenhouse that combines wasteland management and photovoltaic power generation, as well as an eco-city energy conversion, wastewater management and carbon neutrality system green electricity production factory. Background Art

[0002] my country has abundant sunshine resources and vast frozen areas. At present, it is difficult to carry out agricultural planting in frozen areas. For frozen areas with conditions, photovoltaic power generation devices can be installed on the ground. However, this method does not fully utilize frozen areas.

[0003] Eco-city construction mainly involves two major sectors: renewable energy system construction and environmental governance. Regarding renewable energy system construction, green electricity and hydrogen energy are currently the two main renewable energy sources. Green electricity mainly uses solar energy, wind power, biomass energy, geothermal energy, etc., which are produced through production processes with zero or close to zero carbon dioxide emissions. Hydrogen energy is known as the "ultimate energy of the 21st century", and water electrolysis to produce hydrogen is currently one of the main means of hydrogen production. Regarding environmental governance, wastewater and flue gas are the main targets of governance.

[0004] Flue gas often contains a large amount of carbon dioxide produced by combustion. Capturing and utilizing carbon dioxide in flue gas is an important aspect of carbon emission reduction. Carbon capture, utilization and storage (CCUS) technology is the most effective and direct means of carbon emission reduction. In recent years, CCUS technology has made great progress. The technology of synthesizing formaldehyde / methanol using hydrogen produced by water electrolysis and carbon dioxide captured by CCUS technology has matured.

[0005] Wastewater treatment methods mainly include biological methods, electrochemical reaction (electrolysis) methods, membrane treatment methods, ion exchange methods, and evaporation crystallization methods. The biological method is to remove pollutants by oxidizing, decomposing, and adsorbing salts and organic matter in wastewater through the metabolism of microorganisms. The electrolysis method is to remove salts from water through electrolysis. The membrane treatment method uses the membrane's selective permeability differences of each component in the wastewater to separate, purify, and concentrate the target substance. The ion exchange method is a method of removing salts from the raw water by exchanging anions and cations in the saline wastewater with anions and cations fixed by ion exchange resins. The evaporation crystallization method is a method of using the principle of evaporation to evaporate water, increase the salt concentration of the wastewater, and thus precipitate the salt.

[0006] If the effective utilization of permafrost areas is combined with the construction of eco-cities, not only can we make full use of solar energy resources and produce green electricity on a large scale to provide clean energy support for the construction of eco-cities, but we can also promote the coordinated development of energy, environment and economy by building eco-cities in permafrost areas, which is conducive to promoting regional sustainable development.

[0032] Figure 3 This is a diagram of an eco-city energy conversion, wastewater treatment and carbon neutrality system according to an embodiment of the utility model. Figure 3 As shown, the eco-city energy conversion, wastewater treatment and carbon neutrality system realizes the organic combination of energy conversion (green electricity is ultimately converted into fuel), wastewater treatment and carbon neutrality. The eco-city energy conversion, wastewater treatment and carbon neutrality system is specifically constructed as follows:

[0033] The green electricity production system 11 includes a green electricity production operation big data system 111 and a green electricity production plant 112 covered by the green electricity production operation big data system 111 .

[0034] The wastewater purification system 12 includes a wastewater treatment plant 121, and the wastewater treatment plant 121 is used to purify wastewater.

[0035] The water electrolysis hydrogen production system 13 includes a water electrolysis hydrogen production operation big data system 131 and a water electrolysis hydrogen production plant 132 covered by the water electrolysis hydrogen production operation big data system 131.

[0036] The carbon dioxide capture system 14 is provided with a carbon dioxide capture operation big data system 141 and a carbon dioxide capture plant 142 covered by the carbon dioxide capture operation big data system 141 .

[0037] The hydrocarbon synthesis fuel production system 15 includes a hydrocarbon synthesis fuel operation big data system 151 and a hydrocarbon synthesis fuel production plant 152 covered by the hydrocarbon synthesis fuel operation big data system 151 .

[0038] Among them, a green electricity transmission network is established between the green electricity production system 11 and the water electrolysis hydrogen production system 13, a hydrogen transmission network is established between the water electrolysis hydrogen production system 13 and the hydrocarbon synthesis fuel system 15, and a carbon source transmission network is established between the carbon dioxide capture system 1 and the hydrocarbon synthesis fuel production system 15.

[0039] Among them, the electrolysis water hydrogen production system 13 deploys a wastewater purification coupled electrolysis hydrogen production system. The wastewater purification coupled electrolysis hydrogen production system uses the green electricity provided by the green electricity transmission network to electrocatalytically oxidize wastewater and electrolyze water to produce hydrogen. The wastewater purification coupled electrolysis hydrogen production system specifically includes: a first water preparation device to be electrolyzed, a first electrolysis hydrogen production device, a second water preparation device to be electrolyzed, and a second electrolysis hydrogen production device.

[0040] The input end of the first water preparation device to be electrolyzed is connected to the water inlet point in the corresponding wastewater treatment plant 121 and the output end is connected to the first electrolysis hydrogen production device, which is used to adjust the pre-purified wastewater in the wastewater treatment plant 121 into the first water to be electrolyzed.

[0041] The first electrolytic hydrogen production device is used to perform electrocatalytic oxidation coupled hydrogen production on the first water to be electrolyzed, and output electrocatalytically oxidized purified wastewater.

[0042] The input end of the second water preparation device to be electrolyzed is connected to the first electrolytic hydrogen production device and the output end is connected to the second electrolytic hydrogen production device, and is used to adjust the electrocatalytically oxidized purified wastewater into second water to be electrolyzed.

[0043] The second electrolysis hydrogen production device is used to produce hydrogen by alkaline water electrolysis, PEM water electrolysis or brine electrolysis on the second water to be electrolyzed.

[0044] The electrocatalytic oxidation coupled hydrogen production means that the first electrolytic hydrogen production device utilizes the oxidation of the anode (usually a titanium-based metal oxide coating electrode) and / or utilizes the electric field to generate free radicals to promote the oxidation and decomposition of pollutants, thereby achieving wastewater treatment. At the same time, the first electrolytic hydrogen production device 162 utilizes the cathode to generate hydrogen and recycle it. The first electrolytic hydrogen production device does not have high requirements for the water quality of the first water to be electrolyzed, and generally only needs to be removed from suspended matter and oil.

[0045] Among them, the alkaline water electrolysis hydrogen production and PEM water electrolysis hydrogen production are both conventional water electrolysis hydrogen production technologies. In the salt water electrolysis hydrogen production, the second water to be electrolyzed entering the second electrolysis hydrogen production device is salt water, rather than the alkaline water required for alkaline water electrolysis hydrogen production and the pure water required for PEM water electrolysis hydrogen production.

[0046] Since the raw material entering the first water preparation device to be electrolyzed is the wastewater that has been pre-purified in the corresponding wastewater treatment plant 121, the first water preparation device to be electrolyzed no longer needs to perform complex and large-scale wastewater pretreatment (mainly wastewater suspended matter removal treatment equipment and wastewater oil removal treatment equipment).

[0047] Since the first electrolysis hydrogen production device can perform electrocatalytic oxidation treatment on the first water to be electrolyzed, and the electrocatalytic oxidation treatment can effectively remove pollutants (such as organic matter and salt) in the water, it helps to make the second water to be electrolyzed meet the water quality requirements for hydrogen production by alkaline water electrolysis, PEM water electrolysis or brine electrolysis while simplifying the structure and function of the second water preparation device to be electrolyzed.

[0048] In addition, hydrogen production is increased by jointly producing hydrogen through the first electrolysis hydrogen production device and the second electrolysis hydrogen production device.

[0049] Among them, the green electricity production factory of the green electricity production system includes a planting greenhouse that combines wasteland management and photovoltaic power generation.

[0051] The fill layer 212 is formed by screening the original soil excavated from the excavation trench 211 and then screening out the fine aggregate. Specifically, the particle size of the fine aggregate is ≤5 mm.

[0052] The above-mentioned planting greenhouse that combines wasteland management and photovoltaic power generation can be built on frozen land areas around the city. At this time, the depth of the excavated trench can be ≥ the thickness of the frozen soil layer where the excavated trench is located.

[0053] Combining the effective utilization of permafrost areas with the above-mentioned eco-city energy conversion, wastewater treatment and carbon neutrality system can make full use of solar energy resources, produce green electricity on a large scale, provide clean energy support for eco-city construction, and promote the coordinated development of energy, environment and economy by building eco-cities in permafrost areas, which is conducive to promoting regional sustainable development.

[0056] The fill layer 212 is formed by screening the original soil excavated from the excavation trench 211 and then screening out the fine aggregate. Specifically, the particle size of the fine aggregate is ≤5 mm.

[0057] The above-mentioned planting greenhouse that combines wasteland management and photovoltaic power generation can be built on frozen land areas around the city. At this time, the depth of the excavated trench can be ≥ the thickness of the frozen soil layer where the excavated trench is located.

[0058] The greenhouse body is constructed above the corresponding excavated trench. At this time, the greenhouse body is in the shape of a cover and is placed upside down above the corresponding excavated trench, which can simplify the structure of the greenhouse body. The photovoltaic components are arranged on the aisles between adjacent excavated trenches.
