Description

Technical Field

[0001] This invention relates to the field of agricultural facility technology, specifically to an intelligent greenhouse system that integrates photovoltaic and direct air carbon capture functions. Background Technology

[0002] In greenhouse agriculture, increasing CO2 application is a key measure to increase yield and improve quality. Currently, commonly used methods for increasing CO2 application in greenhouses include combustion, chemical methods, and organic fertilizer fermentation. However, these methods are difficult to promote on a large scale due to uncontrollable reactions, high operating costs, and the potential generation of harmful gases in practical applications.

[0003] Solar panels can directly convert solar energy into electrical energy and are widely used in greenhouses to reduce operating energy consumption. However, the power and efficiency of photovoltaic devices are significantly affected by temperature.

[0004] Direct air capture (DAV) is an emerging negative emission technology that captures CO2 directly from the atmosphere through adsorption, showing great potential in addressing global climate change and achieving carbon reduction. Currently, common DAV technologies include adsorption, absorption, and membrane separation. Adsorption is the most frequently used DAV technology, utilizing materials with adsorption properties, such as solid adsorbents, to adsorb carbon dioxide from the atmosphere under certain conditions. Once the adsorption layer reaches saturation, CO2 can be desorbed by changing conditions such as temperature and pressure.

[0005] However, traditional direct air carbon capture systems consume a lot of energy and require additional heat energy to be input into the system during the desorption process. They also face challenges such as high operating costs, low efficiency, and complex equipment, which limit their large-scale application. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent greenhouse system that integrates photovoltaic and direct air carbon capture functions, which significantly improves crop yield and overall energy efficiency, and realizes intelligent, low-cost and efficient operation of greenhouse carbon cycle.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A smart greenhouse system integrating photovoltaic and direct air carbon capture functions includes: a greenhouse body and multiple solar panels.

[0008] Multiple solar panels are fixedly installed on the top of the main body of the greenhouse, and the back of the solar panels is at least partially connected to the interior of the main body of the greenhouse.

[0009] The back of the solar panel is provided with a trapping coating that can come into contact with the air in the main body of the greenhouse.

[0010] In the absence of light, the trapping coating is used to adsorb carbon dioxide released by crops and generate an adsorption heat effect to keep the greenhouse warm inside.

[0011] When there is sunlight, the trapping coating is heated to saturation by the heat generated when the solar panel generates electricity, desorbing and releasing high concentrations of CO2 into the main body of the greenhouse.

[0012] In an intelligent greenhouse system integrating photovoltaic and direct air carbon capture functions provided in at least one embodiment of this disclosure, the back of the solar panel is made of aluminum alloy.

[0013] In an intelligent greenhouse system integrating photovoltaic and direct air carbon capture functions provided in at least one embodiment of this disclosure, the back of the solar panel is sandblasted and roughened.

[0014] The present disclosure provides at least one embodiment of an intelligent greenhouse system integrating photovoltaic and direct air carbon capture functions, wherein the capture coating is a PEI / MCM-41 adsorption coating.

[0015] At least one embodiment of this disclosure provides an intelligent greenhouse system integrating photovoltaic and direct air carbon capture functions, wherein a plurality of solar panels are distributed in a rectangular array.

[0016] At least one embodiment of this disclosure provides an intelligent greenhouse system integrating photovoltaic and direct air carbon capture functions, wherein the solar panels are obliquely disposed on the top of the main body of the greenhouse.

[0017] At least one embodiment of this disclosure provides an intelligent greenhouse system integrating photovoltaic and direct air carbon capture functions, wherein the main body of the greenhouse forms a closed or semi-closed space for growing crops.

[0018] The beneficial effects of this invention are: it significantly improves the overall energy efficiency of crop yield and photovoltaic power generation, and realizes intelligent, low-cost and efficient operation of greenhouse carbon cycle.

[0019] The trapping coating can adsorb CO2 released by the respiration of crops in the greenhouse at night or in the absence of light, and the heat released by the adsorption can keep the greenhouse warm. During the day, the heat generated by the solar panels can be used to heat the saturated coating, desorb the high concentration of CO2 and release it into the greenhouse for plant photosynthesis. At the same time, it can reduce the average temperature of the photovoltaic cells and improve their power generation efficiency and durability. Attached Figure Description

[0024] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments.

[0025] Example like Figure 1 and 2 As shown, this embodiment provides an intelligent greenhouse system integrating photovoltaic and direct air carbon capture functions, including a greenhouse body 10 and a solar power generation system. The solar power generation system consists of a controller (not shown), a battery (not shown) and multiple solar panels 20.

[0026] The back of the solar panel 20 is coated with a PEI / MCM-41 adsorption coating 21. Multiple solar panels 20 are fixedly laid on the top of the greenhouse body 10, and the back of the solar panel 20 is connected to the interior of the greenhouse body 10, so that the PEI / MCM-41 adsorption coating 21 can contact the air inside the greenhouse body 10.

[0027] Specifically, the main body of the greenhouse 10 has an enclosed or semi-enclosed space inside for planting crops, which constitutes the basic environment for crop growth.

[0028] The solar panels 20 are installed at an angle on the top of the main body 10 of the greenhouse, and multiple solar panels 20 are arranged in a rectangular array. The solar panels 20 can convert solar radiation energy into electrical energy to provide supplemental power for the greenhouse's electrical equipment; at the same time, the solar panels 20 can provide heat for the regeneration of the PEI / MCM-41 adsorption coating 21 and desorb CO2.

[0029] Specifically, the PEI / MCM-41 adsorption coating 21 is applied to the back surface of the solar panel 20 through a supersonic cold spraying process, forming a direct air trapping coating. The coating material is an amine-impregnated mesoporous silica composite material.

[0030] Supersonic cold spraying technology utilizes the characteristics of solid-state deposition, which avoids damage to the PEI structure caused by high temperatures, while forming a coating with extremely high bonding strength with the back of the solar panel 20. The carrier gas for this process must be one of nitrogen, helium, or compressed air.

[0031] The back surface of the solar panel 20 is made of aluminum alloy. Before supersonic cold spraying, it needs to be roughened by sandblasting to further enhance the mechanical bonding force between the adsorption coating and the photovoltaic panel.

[0032] At night or in the absence of light, when the greenhouse ventilation system is turned off, the crops inside the greenhouse release CO2 through respiration. The released CO2 is adsorbed by the PEI / MCM-41 coating on the back side of the solar panel 20. While adsorbing CO2, an adsorption heat effect is generated, and the released adsorption heat can keep the greenhouse warm.

[0033] During the day, the solar panel 20 is exposed to solar radiation, converting solar energy into electrical energy. At the same time, the temperature of the solar panel 20 rises, and the heat is transferred to the PEI / MCM-41 coating, causing its temperature to rise. This triggers the desorption of CO2 adsorbed in the saturated coating, and the high concentration of CO2 is released into the greenhouse for crops to carry out photosynthesis.

[0034] In summary, during daytime operation, the solar panel 20 can directly heat the saturated PEI / MCM-41 adsorption coating 21 using the heat generated during power generation, which helps it desorb high concentrations of CO2 and release it into the greenhouse for plant photosynthesis. The PEI / MCM-41 adsorption coating 21 generates a cooling effect when desorbing CO2, which helps to reduce the average operating temperature of the solar panel 20 and improve power generation efficiency. At night, the PEI / MCM-41 adsorption coating 21 can adsorb CO2 produced by crops, and the adsorption heat generated during adsorption can provide insulation for the greenhouse at night.

[0035] Although embodiments of this application have been shown and described above, the scope of protection of this invention is not limited thereto. Any variations or substitutions that can be conceived without inventive effort should be covered within the scope of protection of this invention. Unless expressly stated otherwise, no element, action or instruction used herein should be construed as critical or necessary.
