Description

Technical Field

[0001] The present invention relates to the field of carbon dioxide capture, and in particular to a greenhouse carbon dioxide capture and recycling device. Background Art

[0002] In modern agricultural production, greenhouse cultivation, as an efficient and controllable agricultural production method, has received increasing attention. The greenhouse provides ideal growth conditions for plant growth by adjusting environmental parameters such as temperature, humidity and light. However, in the greenhouse environment, plants consume a large amount of carbon dioxide during photosynthesis, and the concentration of carbon dioxide in the air is often not enough to meet the maximum photosynthetic rate of plants, which limits the growth rate and yield of plants. In order to make up for this deficiency, the existing technology captures and recycles carbon dioxide in the greenhouse;

[0003] After capturing carbon dioxide, existing capture devices often release carbon dioxide into the greenhouse through a fixed spraying assembly. The static release method cannot ensure that the carbon dioxide can be evenly distributed in the greenhouse, and thus cannot enable the carbon dioxide to act efficiently on the surface of plant leaves, which hinders the effective utilization of carbon dioxide and affects the efficiency of plant photosynthesis. In order to solve the above problems, a greenhouse carbon dioxide capture and recycling device is proposed.

The infusion pipe 12 is externally connected to a chemical solvent tank. The chemical solvent tank contains sodium hydroxide. Sodium hydroxide has a strong alkalinity and can react chemically with carbon dioxide. After the air containing carbon dioxide enters the reaction chamber 10, it contacts with the sodium hydroxide input from the infusion pipe 12 and the following chemical reaction occurs. The pH value in the reaction chamber 10 is set to 13 by controlling the input amount of sodium hydroxide. A heating wire 1 is provided in the reaction chamber 10. The temperature of the heating wire 1 is set to 30 degrees Celsius to enhance the reaction rate of carbon dioxide and sodium hydroxide: the primary reaction is CO2+NaOH→NaHCO3, and the secondary reaction is CO2+2NaOH→Na2CO3+H2O. After the reaction, carbon dioxide is captured to obtain water-soluble sodium carbonate.

[0031] A solenoid valve is provided at the top of the connecting pipe 13 to control the sodium carbonate to enter the collecting chamber 19 through the connecting pipe 13. The bottom end extends into the collecting chamber 19 and is fixed with a stirring blade 20. One side of the stirring blade 20 is in contact with the inner wall of the collecting chamber 19. The connecting pipe 13 can rotate in the collecting chamber 19. A heating wire 2 is also provided in the collecting chamber 19. The temperature of the heating wire 2 is set to 120 degrees Celsius. Sodium carbonate can react with water to generate sodium hydroxide and carbon dioxide gas, which helps to further release carbon dioxide. The reaction equation is as follows: Reference Figure 1 The connecting pipe 13 can be rotated on the connecting plate 15 to facilitate the smooth rotation of the collecting chamber 19 and the conveying pipe 21.

[0032] A liftable spraying assembly for spraying carbon dioxide is provided at the bottom of the collecting chamber 19, and the spraying assembly includes a delivery pipe 21, a bellows 22, a nozzle 27, and an air pipe 28. The bellows 22 is fixed between the delivery pipe 21 and the collecting chamber 19, and the nozzles 27 are equidistantly arranged on the delivery pipe 21. An electric push rod 17 is provided at the bottom of the rotating assembly, and the telescopic end of the electric push rod 17 is fixed to the delivery pipe 21. The two ends of the air pipe 28 are respectively connected to the delivery pipe 21 and the inner cavity of the collecting chamber 19. The air pipe 28 is flexible, and the released carbon dioxide enters the delivery pipe 21 through the air pipe 28 and is released into the greenhouse 1 through the nozzle 27. A rotating assembly for driving the spraying assembly to rotate is provided at the top of the greenhouse 1, and the rotating assembly includes a rotating ring 16, an outer gear ring 23, a gear 24, a support seat 25, and a motor 26. The rotating ring 16 rotates at the top of the greenhouse 1, and the temperature A connecting plate 15 is fixed to the top of the chamber 1 through a support frame 11, a rotating ring 16 rotates between the greenhouse 1 and the connecting plate 15, an electric push rod 17 is fixed at the bottom of the rotating ring 16, an outer gear ring 23 is fixed at the top of the rotating ring 16, a gear 24 rotates at the top of the greenhouse 1, a support seat 25 is fixed at the top of the greenhouse 1, a motor 26 is fixed at the top of the support seat 25, a rotor end of the motor 26 is fixed to the gear 24, and the gear 24 is meshed with the outer gear ring 23. In order to ensure uniform release and efficient utilization of carbon dioxide, the electric push rod 17 is started to push the delivery pipe 21 and the nozzle 27 thereon to the height of the plant leaves, and the carbon dioxide is directly released on the plant leaves. At the same time, the motor 26 is started to make the gear 24 drive the outer gear ring 23 and the rotating ring 16 to rotate, thereby driving the electric push rod 17 and the delivery pipe 21 to rotate, so that the distribution of carbon dioxide is more uniform and efficient.

[0033] A mounting frame 18 is also fixed to the bottom of the rotating ring 16, and a collecting chamber 19 is fixed on the mounting frame 18. When the rotating ring 16 rotates, the collecting chamber 19 also rotates synchronously. At this time, the stirring blade 20 and the collecting chamber 19 move relative to each other. Stirring the carbon dioxide in the collecting chamber 19 can effectively prevent the carbon dioxide from forming a concentration gradient in the collecting chamber 19, ensuring that the carbon dioxide is evenly distributed in the entire collecting chamber 19, and promoting the further release of carbon dioxide. The relative stirring of the stirring blade 20 can also prevent the inner wall of the collecting chamber 19 from fouling, thereby maintaining the efficient operation of the capture equipment.

[0034] It should be noted that, through the above technical solution, the carbon dioxide in the greenhouse 1 is effectively captured and recycled, which not only improves the utilization efficiency of carbon dioxide, but also promotes the growth and development of plants.

[0035] Reference Figure 1 A support leg 14 is fixed between the support frame 11 and the connecting plate 15, and the reaction chamber 10 is fixed on the top of the support frame 11. The support frame 11 provides stable support for the reaction chamber 10. The support leg 14 assists the support frame 11 to further support the reaction chamber 10, and can also play a connecting role between the greenhouse 1 and the connecting plate 15.

[0036] Reference Figure 7 , 8 A plurality of through holes 201 are provided on the stirring blade 20, and the cross section of the through hole 201 is hourglass-shaped. When the stirring blade 20 moves relative to the collecting chamber 19, the hourglass-shaped through hole 201 increases the contact area between carbon dioxide and sodium hydroxide, promotes the material exchange between the two, helps to increase the speed and degree of carbon dioxide release, and ensures that more carbon dioxide is separated.

[0037] Reference Figure 1 , 2 The inner wall of the greenhouse 1 is provided with a filter frame 4 corresponding to the mounting hole, the inner diameter of the filter frame 4 is larger than the outer diameter of the mounting hole, a limit ring 5 and a filter element 6 are provided in the filter frame 4, and a limit cover 7 is provided on the filter frame 4. When the limit cover 7 is threadedly connected to the filter frame 4, the filter element 6 is simultaneously fitted with the limit ring 5 and the limit cover 7. The limit ring 5 provides a support point for the filter element 6 to ensure accurate installation of the filter element 6. The filter element 6 is used to filter particulate matter in the air, such as dust and pollen, which can effectively reduce the impurity content entering the reaction chamber 10, thereby facilitating the capture efficiency of carbon dioxide. The filter element 6 is clamped between the limit ring 5 and the limit cover 7 to ensure the stability of the filter element 6, and will not be deformed or fall off due to airflow impact. At the same time, the limit cover 7 cooperates with the thread of the filter frame 4, which is convenient for replacing and cleaning the filter element 6, reducing the workload and time cost of daily maintenance. Preferably, the filter element 6 can be activated carbon.

[0038] Reference Figure 1 The mounting hole is opened at the bottom of the inner wall of the greenhouse 1, so the fan 3 is also located at the bottom. The fan 3 located at the bottom can effectively draw air from the bottom of the greenhouse 1, promote the airflow from bottom to top, and help break the stratification of the air in the greenhouse 1. Especially at night or in the absence of light, more carbon dioxide will accumulate near the ground, so carbon dioxide can be captured more efficiently. At the same time, by drawing air from the bottom and transporting it to the reaction chamber 10 at the top, it can ensure that the air in the entire greenhouse 1 is fully mixed, avoiding the problem of excessive or low local carbon dioxide concentration, and providing a more uniform growth environment for plants.
