[0002] As a clean energy, solar energy is of great significance to reducing greenhouse gas emissions and addressing climate change. It is estimated that by 2030, solar photovoltaic power generation will account for more than 10% of the world's total electricity supply, which shows its important strategic position in the energy field. When solar photovoltaic panels are working, the output power of photovoltaic panels will decrease with the increase of temperature. Generally, the efficiency will decrease by about 0.5% for every 1°C increase. In addition, high temperature will accelerate the aging of materials and shorten the service life of photovoltaic panels. Therefore, thermal management of photovoltaic panels is required to ensure the high performance output of photovoltaic panels.

[0003] In addition, with the rapid economic development and population growth, the amount of sewage discharged due to urbanization is increasing, especially organic sewage. This type of sewage often contains many toxic and harmful organic substances. If it is not treated or treated inadequately, it will have a significant impact on the ecological environment, human health and the sustainable development of the social economy.

[0004] Therefore, if the solar power generation system can be coupled with the sewage treatment system to use the solar power generation system to provide energy for sewage treatment and use sewage to perform thermal management on the solar power generation system, the two major problems of the solar energy system's difficulty in maintaining high-performance continuous output and insufficient sewage treatment can be solved at the same time. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a solar photovoltaic thermal management system with organic wastewater degradation function, comprising a water storage unit, a wastewater degradation unit and a clean water storage unit; the water storage unit is used to input the stored wastewater into the wastewater degradation unit for degradation treatment; the wastewater degradation unit comprises a heat dissipation frame, a solar photovoltaic panel, a glass plate and photothermal microcapsules; a degradation cavity is provided inside the heat dissipation frame, and the degradation cavity is respectively connected and communicated with the water storage unit and the clean water storage unit; the heat dissipation frame is provided with a photolysis tank and a plurality of installation cavities above the degradation cavity, and the photolysis tank is communicated with the degradation cavity; a plurality of solar photovoltaic panels are respectively arranged in a plurality of installation cavities; the glass plate covers and closes the photolysis tank and the plurality of installation cavities; the photothermal microcapsules are filled in the degradation cavity and the photolysis tank; the clean water storage unit is used to store clean water treated by the wastewater degradation unit.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] The present invention provides a solar photovoltaic thermal management system with organic wastewater degradation function, which can be implemented as follows: Figure 1 As shown, it includes a water storage unit 10 , a sewage degradation unit 20 and a clean water storage unit 30 .

[0029] Regarding the water storage unit 10, Figure 1 As shown, the water storage unit 10 is used to input the stored sewage into the sewage degradation unit 20 for degradation treatment, that is, the main function of the water storage unit 10 is to store and transport sewage. Therefore, in order to achieve this purpose, this embodiment first uses aluminum alloy to make the water storage unit 10 with a sewage storage cavity, which is not only low in cost but also has high corrosion resistance, so that it can meet the storage function of various sewage. Secondly, when transporting sewage, this embodiment uses a water pump to pump the sewage from the inside of the water storage unit 10 to the sewage degradation unit 20, thereby realizing the transportation of sewage.

[0030] Regarding the sewage degradation unit 20, Figures 1 to 5 As shown, the sewage degradation unit 20 includes a heat dissipation frame 21, a solar photovoltaic panel 22, a glass plate 23 and photothermal microcapsules 24.

[0031] The heat dissipation frame 21 has a rectangular shape, and a degradation chamber 211 is provided inside the heat dissipation frame 21. In the direction shown in the figure, the degradation chamber 211 penetrates the left and right sides of the heat dissipation frame 21, so that the degradation chamber 211 can be connected to the water storage unit 10 and the clean water storage unit 30 respectively; and because the heat dissipation frame 21 is arranged obliquely with the left side lower and the right side higher in the direction shown in the figure, the degradation chamber 211 is also arranged obliquely. At this time, the upper part of the degradation chamber 211 will be connected to the water storage unit 10, and the lower part of the degradation chamber 211 will be connected to the clean water storage unit 30.

[0032] In addition, the heat dissipation frame 21 is provided with a photolysis tank 212 and a plurality of installation cavities 213 above the degradation cavity 211; the photolysis tank 212 passes through from the top surface of the heat dissipation frame 21 to the inside of the degradation cavity 211, so that the photolysis tank 212 is connected to the degradation cavity 211; and the installation cavity 213 is a cavity structure formed by being recessed inward from the top surface of the heat dissipation frame 21, and the plurality of installation cavities 213 are arranged separately from each other, so that the photolysis tank 212 can be provided in the areas where the plurality of installation cavities 213 are separated from each other; for example, the installation cavities 213 in this embodiment are four in total, and after the four installation cavities 213 are arranged in a matrix form, the photolysis tank 212 can be set in a cross shape, so that the photolysis tank 212 can separate the four installation cavities 213 from each other.

[0033] Furthermore, since the heat dissipation frame 21 needs to be used to install the solar photovoltaic panel 22 and the photothermal microcapsule 24, in order to facilitate the efficient heat transfer of the solar photovoltaic panel 22 and prevent the photothermal microcapsule 24 from corroding the heat dissipation frame 21, this embodiment sets the heat dissipation frame 21 to be an aluminum alloy frame, so as to utilize the excellent thermal conductivity of the aluminum alloy to improve the heat transfer efficiency of the solar photovoltaic panel 22, and utilize the stable chemical properties of the aluminum alloy to improve the corrosion resistance of the heat dissipation frame 21.

[0034] Obviously, after the heat dissipation frame 21 adopts the above-mentioned setting method, multiple solar photovoltaic panels 22 can be respectively arranged in multiple installation cavities 213, thereby realizing the separate installation and fixation of multiple solar photovoltaic panels 22; wherein, the solar photovoltaic panel 22 of this embodiment is a silicon photovoltaic panel.

[0035] In order to prevent the photothermal microcapsules 24 in the photolysis tank 212 from corroding the solar photovoltaic panel 22, this embodiment uses the glass plate 23 to cover and seal the photolysis tank 212 and the multiple installation cavities 213, so that the photolysis tank 212 and the multiple installation cavities 213 form independent closed spaces, providing good installation protection for the solar photovoltaic panel 22.

[0036] Finally, in order to achieve the degradation of sewage, this embodiment fills the photothermal microcapsules 24 into the degradation chamber 211 and the photolysis tank 212 .

[0037] Specifically, the photothermal microcapsule 24 of this embodiment includes a core layer material and a shell layer material, wherein the shell layer material is wrapped around the core layer material; the core layer material is one or more of C14-C22 alkanes or C14-C22 fatty alcohols; the shell layer material is silicon dioxide; and the plasma exciton material ionic compound is chloroauric acid, copper nitrate or silver nitrate.

[0038] The preparation method of the photothermal microcapsule 24 is as follows:

[0039] S1. The core-shell structured phase change microcapsules are ultrasonically stirred in an n-type semiconductor precursor, and a semiconductor-wrapped double-shell structured phase change energy storage microcapsules are obtained by a hydrothermal method;

[0040] S2. Dispersing the double-shell structure phase change energy storage microcapsules into an aqueous solution containing a plasmon material ionic compound, and stirring under light conditions to obtain the photothermal synergistic catalytic hydrogen production microcapsules.

[0041] The photothermal microcapsule 24 of this embodiment includes an exposed microcapsule 241 and an internal microcapsule 242 . The exposed microcapsule 241 is disposed in the photolysis tank 212 , and the internal microcapsule 242 is disposed in the degradation chamber 211 , and the exposed microcapsule 241 and the internal microcapsule 242 are in contact with each other.

[0042] The exposed microcapsules 241 can be more fully exposed to sunlight so as to stimulate the catalytic performance of themselves and the internal microcapsules 242 after absorbing solar energy. In this process, the shell material of the photothermal microcapsules 24 will absorb and store the excess heat energy after catalytic stimulation and part of the heat of the solar photovoltaic panel 22. The photothermal microcapsules 24 with catalytic ability will react with the organic matter in the sewage to achieve the degradation of the sewage. In this process, the flow of sewage under the solar photovoltaic panel 22 further reduces the temperature of the solar photovoltaic panel 22. After two heat absorptions, the temperature of the solar photovoltaic panel 22 can be maintained in a suitable range, so that it can maintain high performance output; the treated water finally flows into the clean water storage unit 30 for storage.

[0043] In addition, in order to increase the contact area between the photothermal microcapsules 24 and the sewage, this embodiment also compresses the internal microcapsules 242 into a tube shape, so that the internal microcapsules 242 can undergo a more complete degradation reaction with the sewage, greatly improving the degradation treatment efficiency of the sewage.

[0044] Regarding the clean water storage unit 30, Figure 1 As shown, the clean water storage unit 30 is used to store the clean water treated by the sewage degradation unit 20. Therefore, to achieve this purpose, this embodiment uses aluminum alloy material to make the corresponding liquid storage tank, so that the storage and collection of clean water can be completed.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
