Description

Technical Field

[0001] This utility model relates to a building equipment with economic output value, and in particular to an algae cultivation green building system. Background Technology

[0002] Given the growing and urgent threat that climate change poses to the environment and human survival, more than 130 countries worldwide have declared and taken action to achieve "net zero emissions by 2050" for carbon dioxide. Among these efforts, diversified green energy and carbon emission reduction are both ways to achieve net zero emissions.

[0003] To reduce atmospheric carbon dioxide, in addition to reducing emissions, capturing and storing carbon dioxide in the air is also an important technological approach. Among these methods, biological carbon sequestration utilizes photosynthetic organisms to convert carbon dioxide into hydrocarbons, while simultaneously producing large amounts of biomass that can be used as fertilizer, fuel, and other resources. Therefore, biological carbon sequestration is currently one of the most energy-efficient and environmentally friendly methods.

[0004] Therefore, how to combine biocarbon sequestration with other green energy sources to achieve the goal of net-zero emissions more quickly is the direction that relevant businesses are striving for. Utility Model Content

[0021] The features and technical content of the related patent applications of this utility model will be clearly presented in the following detailed description of the preferred embodiments with reference to the accompanying drawings. Before the detailed description, it should be noted that similar components are represented by the same numbers. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, back, bottom, and top, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present utility model.

[0022] See Figure 1 This is a first preferred embodiment of the algae cultivation green building system of the present invention, comprising a cultivation device 2 and a shading device 3 for partially covering the cultivation device 2. The cultivation device 2 includes a plurality of algae cultivation units 21 and a gas supply unit 22. The gas supply unit 22 can be an air pump or other machine capable of producing the same effect, supplying gas to the algae cultivation units 21 and controlling the gas pressure, as understood by those skilled in the art; therefore, its detailed structure is not shown in the figures.

[0023] The algae cultivation units 21 are interconnected to form a closed-loop circulating cultivation space. The gas supply unit 22 can supply gas to the algae cultivation units 21. Part of the algae cultivation units 21 are shielded by the shielding device 3 and located in a shielded area 301, while another part of the algae cultivation units 21 are not shielded by the shielding device 3 and are located in an unshielded area 302, so that the cultivation equipment 2 can simultaneously carry out light and carbon reactions. Photosynthesis is generally divided into "light reaction" and "dark reaction," and currently, most textbooks refer to the dark reaction as the "carbon reaction." The dark reaction refers to a "reaction that does not require light," and its main function is to fix carbon dioxide, so calling it the carbon reaction is more appropriate. More specifically, the light reaction requires light and converts light energy into chemical energy (ATP, NADPH), which is then used by the carbon reaction. The carbon reaction mainly utilizes enzymes to synthesize glucose and water from carbon dioxide and chemical energy, thus having a carbon fixation function. Because the products of the light-dependent photoreaction can be used in the carbon-dependent photoreaction, high light intensity leads to an excessive amount of these products, thus limiting the overall efficiency of photosynthesis. Similarly, low light intensity also limits the overall efficiency of photosynthesis due to the rate at which reactants are produced. Therefore, some studies suggest that at low light intensity, increasing light intensity leads to increased photosynthetic efficiency, while temperature and carbon dioxide concentration have little effect. However, at higher light intensity, photosynthetic efficiency no longer increases with light intensity, but significantly improves with higher temperature or carbon dioxide concentration. Specifically, photosynthetic efficiency rapidly decreases when the temperature exceeds 35°C. This indicates that higher temperature and stronger light do not necessarily lead to better photosynthetic efficiency; proper regulation of temperature and light is key to maximizing photosynthetic efficiency.

[0024] The shading device 3 includes a support unit 31 and a shielding unit 32 disposed on the support unit 31. The shielding unit 32 is used to shield a portion of the algae cultivation unit 21. In this embodiment, the shielding unit 32 includes a shielding platform 321. More specifically, if the shading device 3 is in the form of a factory building, the shielding platform 321 can be a roof, balcony, or terrace of the factory building, or other architectural structures that can provide a shielding effect. A portion of the algae cultivation unit 21 is shielded by the shading device 3, that is, it is located in the shielded area 301 below the shielding platform 321, to avoid direct sunlight exposure and allow for carbon reactions. The other portion of the algae cultivation unit 21 is not shielded by the shading device 3 and is located in the unshaded area 302, where it can directly receive sunlight and undergo photoreactions. Since the algae cultivation unit 21 is designed in series and is a closed-loop cultivation space, it can adjust the light intensity or temperature when the shaded area 301 and the unshaded area 302 are too strong or the temperature is too high. At the same time, the cultivation equipment 2 as a whole can be regarded as simultaneously carrying out the light reaction (unshaded area 302) and the carbon reaction (shaded area 301), which helps to accelerate algae growth and improve photosynthetic efficiency, and further improve carbon fixation efficiency.

[0025] In addition, at least one of the algae cultivation units 21 has a drain valve 211. Preferably, the drain valve 211 can be installed on one of the shaded algae cultivation units 21. In this way, the operator can perform algae harvesting and other procedures below the shaded platform 321 by controlling the drain valve 211. The shaded platform 321 provides a better working environment to avoid exposure to sunlight or rain for the operator.

[0026] See Figure 2This is a second preferred embodiment of the algae cultivation green building system of the present invention. The difference from the first preferred embodiment is that the shading unit 32 further includes a plurality of solar panels 322. More specifically, the shading unit 32 provides a shading effect by constructing a plurality of solar panels 322. A portion of the algae cultivation units 21 are shaded by the shading device 3, that is, they are located in the shading area 301 below the solar panels 322 to avoid direct sunlight and allow carbon reactions to occur. The other portion of the algae cultivation units 21 are not shaded by the shading device 3 and are located in the unshaded area 302, where they can directly receive sunlight and undergo photoreactions. Simultaneously, in addition to providing shading, the solar panels 322 can also perform photoelectric conversion to generate electricity. The shading device 3 further includes an energy storage unit 33 electrically connected to the solar panels 322, and the gas supply unit 22 of the cultivation device 2 is electrically connected to the energy storage unit 33. Therefore, the aquaculture equipment 2 can operate using the electricity generated by the solar panel 322.

[0027] In addition to achieving the effects mentioned in the first preferred embodiment, such as accelerating algae growth and improving photosynthetic efficiency, the second preferred embodiment also has energy-saving effects through the installation of the solar panel 322. Furthermore, this embodiment generates sufficient biomass by using the solar panel 322 in conjunction with the algae cultivation unit 21, thus complying with agricultural land use regulations and thereby revitalizing idle farmland.

[0028] As can be seen from the above description, the algae cultivation green building system of this utility model has the following effects: 1. It helps to accelerate algae growth and improve photosynthetic efficiency: Through the shading device 3, part of the cultivation device 2 is located in the shading area 301 and the other part is located in the non-shading area 302. Since the algae cultivation units 21 of the cultivation device 2 are connected in series to form a closed-loop cultivation space, the cultivation device 2 can be regarded as simultaneously carrying out light reaction and carbon reaction, which helps to accelerate algae growth and improve photosynthetic efficiency, and further improve carbon fixation efficiency.

[0029] 2. Making good use of idle farmland: If the present invention uses solar panel 322 in combination with algae cultivation unit 21 to produce sufficient biomass, it can meet the farmland use standards and thereby revitalize idle farmland.

[0030] In summary, this novel algae cultivation green building system, through the arrangement of shaded area 301 and unshaded area 302, combined with the closed-loop circulating cultivation space of the cultivation device 2, allows the device 2 to simultaneously carry out light and carbon reactions. This helps accelerate algae growth and improve photosynthetic efficiency, while utilizing algae for carbon sequestration to achieve carbon reduction. The biomass can also be reused as fertilizer and fuel. Furthermore, when the cultivation device 2 is installed in conjunction with solar panels 322, it can produce sufficient biomass, thus complying with agricultural land use regulations and revitalizing idle farmland, effectively achieving the purpose of this invention.

[0031] However, the above description is only a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. All simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
