Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of microalgae carbon fixation, and particularly relates to a telescopic claw type microalgae photobioreactor with built-in light arrangement. BACKGROUND

[0002] With the increasingly serious global climate change problem, reducing carbon dioxide emissions and achieving carbon neutrality have become the core issues of common concern of countries around the world. As a kind of efficient photosynthetic organism, microalgae has great application potential in the field of carbon capture and utilization due to its excellent carbon fixation capacity and environmental adaptability. Microalgae can convert carbon dioxide into organic matter through photosynthesis while releasing oxygen, which not only can effectively reduce the concentration of carbon dioxide in the atmosphere, but also can produce high-value biomass products such as biofuels, food additives and pharmaceutical raw materials, so as to realize efficient utilization of resources.

[0003] However, although the microalgae carbon fixation technology has significant advantages in the theoretical level, it still faces many challenges in practical application. First, the photosynthesis efficiency of microalgae is directly affected by the light conditions. The traditional microalgae culture system usually uses fixed light source or natural light as the main light source, but due to the fluctuation of the direction and intensity of sunlight with time and weather, the light distribution is uneven, which affects the growth rate and carbon fixation efficiency of microalgae. In addition, in the process of large-scale cultivation, the problem of light attenuation is particularly prominent, especially under high-density cultivation conditions, the light energy is difficult to penetrate the culture solution to reach the deep layer of microalgae cells, which further limits the improvement of carbon fixation capacity.

[0004] Secondly, sufficient carbon dioxide supply is required for the process of microalgae carbon fixation. The existing microalgae reactor often has the problem of uneven gas distribution, which leads to too low carbon dioxide concentration in some areas, while gas waste may occur in other areas. This unbalanced gas supply not only reduces the utilization rate of carbon dioxide, but also increases the operating cost. In addition, the design of traditional reactor usually occupies a large area, which is difficult to meet the actual demand of efficient carbon fixation, especially in the scenes of limited land resources such as cities or industrial areas.

[0030] In an embodiment of the application, the telescopic main rods 5 are driven by the electric push rods 6 to move, so that the lamp tubes 3 are moved, and the distance between the lamp tubes 3 and the microalgae is adjusted.

[0033] As an optional implementation, the gas adjustment piece comprises a gas distribution plate 9, the gas distribution plate 9 is fixedly connected to the inner bottom of the reactor main body 1 and located below the central shaft.

[0042] In one embodiment of the present application, the reactor body 1 and the reactor top plate 2 are both made of light-transmitting material, which ensures the irradiation of sunlight on the microalgae.

[0043] The present application provides a telescopic claw type microalgae photobioreactor with built-in light arrangement. In use, the electric push rod 6 is installed on the outer side of the central shaft, and the piston rod end is directly connected with the main rod 5. By receiving instructions from the controller, the electric push rod 6 can push or pull the main rod 5 to realize telescopic movement. Each section of the main rod 5 is connected with a hinge structure, so that the main rod 5 can freely rotate and telescope within a certain range. This design ensures that the lamp tube 3 can be adjusted at multiple angles and multiple levels in three-dimensional space. Under sunny conditions, the direction and intensity of sunlight will change over time and weather. The reactor achieves the best light supplement effect by the following steps: when sunlight shines from different directions, the main rod 5 rotates through the hinge structure, so that the lamp tube 3 always faces the incident direction of sunlight, forming a complementary light distribution. When the sun is strong at noon, all lamp tubes 3 can be turned off. On cloudy days or at night, due to insufficient natural light, the full power operation mode of the lamp tube 3 is started, and the electric push rod 6 adjusts the lamp tube 3 to the middle of the central shaft of the telescopic frame 4 and the outer wall of the reactor body 1, providing uniform and sufficient light conditions for microalgae. When the light is sufficient during the day, but still cannot meet the growth needs of microalgae, the electric push rod 6 adjusts the lamp tube 3 to be close to the central shaft of the telescopic frame 4, avoiding damage to microalgae cells due to excessive light. Through the above detailed light adjustment design, the telescopic claw type microalgae photobioreactor with built-in light arrangement of the present application can always maintain high-efficiency light supplement effect under various external sunlight conditions, providing an ideal growth environment for microalgae cultivation, and further improving the performance and application value of the reactor.

[0044] The telescopic claw structure of the present application can dynamically change the light distribution according to the actual needs of microalgae cultivation, thereby significantly improving the light energy utilization efficiency and providing a more uniform light environment for microalgae, promoting their growth and metabolic activity. According to the direction of sunlight, the light supplement angle and position of the lamp tube are dynamically adjusted to the optimal angle complementary to the sunlight; on cloudy days or at night, artificial light sources can be completely relied on for efficient light supplement, ensuring that the best light supplement can be provided for microalgae at different time periods or weather conditions. The reactor body and top plate made of light-transmitting material and the efficient light distribution design maximize the use of natural light and artificial light sources, reducing energy consumption, and can be widely used in the fields of biology, environmental protection, etc.
