Abstract
Description
Technical Field
[0001] This invention relates to the interdisciplinary field of environmental engineering and textile biomaterials, and in particular to an artificial biomimetic leaf carbon fixation and oxygen production device. Background Technology
[0002] Since the beginning of the 21st century, global warming has become increasingly severe, causing numerous environmental problems such as rising sea levels, redistribution of global precipitation, frequent droughts and floods, and other extreme weather events. It affects the steady and healthy development of the global economy, even leading to regional imbalances, wars over resources, and a sharp decline in population. The root cause of these problems lies in the level of carbon dioxide. Carbon dioxide is a primary reactant in photosynthesis by plants and microorganisms (such as algae), and also a product of respiration by animals, plants, and microorganisms. Furthermore, the large-scale burning of fossil fuels (such as coal and oil) by humans emits carbon dioxide gas, which is highly transparent to short-wave solar radiation but highly absorbent of long-wave radiation reflected from the Earth, thus causing global warming and the greenhouse effect.
[0003] According to the photosynthetic mechanism of plants and microorganisms (such as algae), carbon dioxide, as one of the reactants, not only produces polysaccharides (such as glucose, maltose, and starch) but also contains oxygen. Therefore, effectively absorbing and converting carbon dioxide in the air can not only reduce carbon dioxide levels and inhibit global warming, but also convert it into oxygen, thus purifying the air. Furthermore, the polysaccharides produced by fixing carbon dioxide can be effectively utilized by humans, achieving a collection and utilization effect. On the one hand, traditional household air purifiers only use mechanical filters, ultraviolet light, negative ions, and photocatalytic air purification, which only fix carbon and cannot truly achieve oxygen production and energy conversion. On the other hand, recent studies show that using microalgae as an air purification carrier for air filtration, carbon dioxide fixation, and oxygen production requires an aeration device to supply gas to the reactor, which has disadvantages such as large volume space requirements, high operational technical difficulty, reliance on external energy supply, and excessively high conversion efficiency. To date, there is no large-scale use of household carbon fixation and oxygen production devices that do not require external energy.
[0004] Based on this, this application is made. The present invention uses textiles coated with a gel layer containing microalgae, and designs an artificial leaf plate device based on biomimetic structural design to simulate the structure of leaf veins, and transports and refluxes the microalgae culture medium, providing a natural simulation design for the growth of microalgae, ensuring normal physiological functions, and performing carbon fixation and oxygen production. This provides a novel carbon fixation and oxygen production device for home air purification, carbon energy collection, and global warming inhibition. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] The purpose of this invention is to provide an artificial biomimetic leaf carbon fixation and oxygen production device to solve the problems existing in the prior art.
[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] Example 1:
[0034] This embodiment provides an artificial biomimetic leaf-based carbon sequestration and oxygen production device, such as... Figure 1-4 As shown, it includes an artificial leaf plate system, which contains a microalgae culture system and is connected to a culture medium delivery system and an oxygen collection system.
[0035] Specifically, the artificial leaf plate system includes a first frame 1 and a second frame 2. Both the first frame 1 and the second frame 2 are provided with screw holes 3, and the two are joined together by bolts. The microalgae biological culture system is sandwiched between the first frame 1 and the second frame 2.
[0036] Furthermore, both the first frame 1 and the second frame 2 are made of acrylic material.
[0037] Furthermore, the preparation method of the microalgae-containing biological culture system includes the following steps:
[0038] S11. The silkworm silk is subjected to degumming, dissolving, dialysis and concentration steps in sequence to obtain a 4-6% silk fibroin solution;
[0039] S12. Mix the silk fibroin solution with horseradish peroxidase at a concentration of 1000 U / mL at a ratio of 1:20 to obtain a mixed solution;
[0040] S13. Add 1.0 × 10 to the mixed solution. 5 cells / mL ~ 1.0 × 10⁻⁶ 7Microalgae at a ratio of 1 / mL were pipetted evenly and then transferred into a 37°C biological incubator for 10–20 min to obtain a microalgae gel mixture.
[0041] S14. Apply the microalgae gel mixture to the surface of the textile layer using a brush.
[0042] The microalgae culture system is held within an artificial leaf plate system, ensuring that the coating of the microalgae gel mixture faces inward. From the outside in, the layers are: second frame 2, textile layer, microalgae gel mixture, and first frame 1.
[0043] Furthermore, the textile layer uses 10Tex ultrafine polyester plain weave fabric, which has high light transmittance and breathability.
[0044] Furthermore, the culture medium delivery system includes a nutrient solution input pipe 4 and a nutrient solution output pipe 5. The nutrient solution input pipe 4 is located at the top of the artificial leaf plate system, and the nutrient solution output pipe 5 is located at the bottom of the artificial leaf plate system. A nutrient solution delivery network 6 connects the nutrient solution input pipe 4 and the nutrient solution output pipe 5.
[0045] The microalgae culture medium is introduced into the artificial leaf plate system through the nutrient solution input pipe 4 to ensure the normal growth of microalgae. After a period of cultivation, the waste liquid flows out through the nutrient solution output pipe 5. The above steps are then repeated to ensure that the microalgae culture medium in the artificial leaf plate system is fresh and does not affect its normal cultivation.
[0046] Furthermore, the oxygen collection system includes an oxygen cylinder, which is detachably connected to the nutrient solution inlet pipe 4.
[0047] After a period of photosynthesis, the algae-containing microbial culture system produces a certain amount of oxygen, which gradually rises through the nutrient solution input pipe 4 and is discharged to the outside. On the one hand, it can be directly discharged into the room as an outdoor household air purification system to release fresh negative oxygen ions and improve air quality; on the other hand, a special oxygen collection device can be used to store it in an oxygen cylinder for easy reuse.
[0048] This invention provides an artificial biomimetic leaf-based carbon fixation and oxygen production device. Using microalgae as an air purification carrier, it utilizes photosynthesis to fix carbon dioxide, produce oxygen, and simultaneously generate carbon-containing energy. This achieves, to a certain extent, the combined effects of air purification, mitigating global warming, and collecting energy materials. It also promotes cross-fertilization and collaboration among the textile materials, biological, environmental engineering, and energy sectors.
[0049] This invention, based on the biomimetic structure of natural tree leaves, designs a novel flat-plate device that utilizes its own vein structure to deliver microalgae culture medium. This ensures that the gel containing microalgae is fully immersed in the culture medium, guaranteeing the normal growth and function of the microalgae. The delivery of the culture medium requires no external energy source, such as electrical infusion, fully leveraging the structural advantages to achieve specific functional effects. Furthermore, its novel design appeals to human aesthetics and serves as a decorative element when placed indoors.
[0050] This invention comprises three layers: from the outside in, a gel layer containing microalgae, a textile layer, and an artificial leaf layer. The gel layer containing microalgae utilizes the adhesive properties of gel to firmly adhere to the textile layer, eliminating the need for other chemical adhesives and ensuring ample contact between the textile layer and the surrounding airflow. Unlike other methods that rely on aeration devices for air delivery, this invention reduces the need for electrical equipment, effectively saving energy and preventing energy deficits.
[0051] This invention utilizes the inherent physiological advantages of microalgae to achieve their suspended growth within a gel. Due to the high permeability of silk fibroin gels, theoretically, multi-layered arrangements of algae can be achieved under certain light transmittance conditions, unlike the single-layer arrangement of algae in traditional carbon fixation devices, thus effectively improving utilization. Furthermore, the microalgae have a longer growth period, eliminating the need for frequent replacement, and also offer advantages such as small footprint and low energy consumption.
[0052] During the cultivation process, the viability values of different numbers of microalgae were periodically measured using an ELISA reader, and the results were as follows: Figure 3 As shown, images of the microalgae's growth morphology obtained through staining with rhodamine and phalloidin dyes, as well as bright-field observation, are shown below. Figure 4 As shown.
[0053] Example 2:
[0054] As a variation of Example 1, this example provides another preparation method for a microalgae-containing biological culture system, comprising the following steps:
[0055] S21. The silkworm silk is subjected to degumming, dissolving, dialysis and concentration steps in sequence to obtain an 8-10% silk fibroin solution;
[0056] S22. A mixed solution is obtained by mixing silk fibroin solution and polyethylene glycol 400 solution with a mass fraction of 80% at a ratio of 1:1;
[0057] S23. Add 1.0 × 10 to the mixed solution. 5 cells / mL ~ 1.0 × 10⁻⁶ 7 Microalgae were mixed evenly using a pipette to obtain a microalgae solution at a ratio of 1 / mL.
[0058] S24. Pour the microalgae solution into a small spray bottle, spray it evenly onto the surface of the textile layer, and then place it in a 37°C biological incubator for 30 minutes until it is completely gelled.
[0059] Except for the preparation steps described above, the structure and effects of this embodiment are the same as those of Example 1.
[0060] This invention has illustrated its principles and implementation methods using specific examples. The descriptions of these embodiments are merely illustrative of the method and its core ideas; furthermore, those skilled in the art will recognize that modifications may be made to the specific implementation methods and application scope based on the principles of this invention. Therefore, the content of this specification should not be construed as limiting the invention.
