[0003] The physical and chemical methods for carbon treatment in the prior art are not only complex in structure and high in cost, but also prone to secondary pollution. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a carbon emission absorption device, comprising a main shed connected to the atmosphere, at least one sub-shed arranged within the main shed, and an exhaust gas delivery pipeline connected to each of the sub-sheds, wherein plants are planted inside the sub-sheds and the sub-sheds can be sealed or opened to connect to the atmosphere. The exhaust gas delivery pipeline is used to introduce exhaust gas into each of the sub-sheds, and the exhaust gas delivery pipeline is respectively provided with a valve on the communication path with each of the sub-sheds;

The controller is capable of closing the corresponding valve when the carbon dioxide and oxygen concentrations inside the sub-shed meet a first preset condition, and opening the corresponding sub-shed when the carbon dioxide and oxygen concentrations inside the sub-shed meet a second preset condition.

[0007] Among them, the first preset condition is that the carbon dioxide concentration reaches the saturation point. Once it exceeds the saturation point, even if the CO2 concentration increases further, the plant photosynthetic intensity will no longer increase. The saturation point is related to the specific plant species planted inside the sub-shed; the second preset condition is that the carbon dioxide concentration and oxygen concentration are equivalent to those of the atmosphere.

[0008] In the carbon emission absorption device of the present invention, plants are planted inside each sub-shed.

When the carbon dioxide concentration meets the first preset condition, the corresponding valve is closed and the exhaust gas input is stopped. The plants inside the sub-shed carry out photosynthesis to convert carbon dioxide into oxygen. The carbon dioxide and oxygen concentrations in the sub-shed are continuously detected by the first detection unit. After a predetermined time, when the carbon dioxide and oxygen concentrations in the sub-shed meet the second preset condition, the corresponding sub-shed is opened to connect to the atmosphere, and the above steps are repeated to complete the exhaust gas purification work. The operating principles of different sub-sheds are the same.

[0009] Therefore, the carbon emission absorption device of the present invention utilizes plant photosynthesis to absorb carbon, has a simple structure, low cost, and is green and environmentally friendly.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The words "first", "second", etc. mentioned in this article are only used to facilitate the description of two or more structures or components with the same or similar structures and / or functions, and do not mean any special limitation on the order and / or importance.

[0028] Please refer to Figures 1 to 3 , Figure 1 This is a structural schematic diagram of a specific embodiment of the carbon emission absorption device provided by the present invention; Figure 2 for Figure 1 Front view of the carbon emission absorption device; Figure 3 for Figure 1 Left side view of the carbon emission absorption device.

[0029] The present invention provides a carbon emission absorption device, comprising a main shed 1 connected to the atmosphere, at least one sub-shed 2 arranged in the main shed 1, and an exhaust gas delivery pipeline 3 connected to each sub-shed 2. Plants 01 are planted inside the sub-shed 2, and the sub-shed 2 can be sealed or opened to connect to the atmosphere. The exhaust gas delivery pipeline 3 is used to introduce exhaust gas into each sub-shed 2. The exhaust gas delivery pipeline 3 is respectively provided with a valve on the communication path with each sub-shed 2.

[0030] It also includes a first detection unit arranged inside the sub-shed 2, and a controller 4 electrically connected to the first detection unit, the sub-shed 2, and the valve. The first detection unit can detect the carbon dioxide concentration and oxygen concentration inside the sub-shed 2. The controller 4 can close the corresponding valve when the carbon dioxide concentration inside the sub-shed 2 meets the first preset condition, and open the corresponding sub-shed 2 when the carbon dioxide and oxygen concentrations inside the sub-shed 2 meet the second preset condition.

[0031] Among them, the first preset condition is that the carbon dioxide concentration reaches the saturation point. Once the saturation point is exceeded, even if the CO2 concentration increases further, the photosynthetic intensity of the plant 01 will no longer increase. The saturation point is related to the specific type of plant 01 planted inside the sub-shed 2; the second preset condition is that the carbon dioxide concentration and oxygen concentration are equivalent to those of the atmosphere.

[0032] In the carbon emission absorption device of the present invention, plants 01 are planted inside each sub-shed 2. During operation, the sub-shed 2 is first sealed and the exhaust gas is passed into the sub-shed 2. When the carbon dioxide concentration meets the first preset condition, the corresponding valve is closed and the exhaust gas input is stopped. The plants 01 inside the sub-shed 2 carry out photosynthesis to convert carbon dioxide into oxygen. The carbon dioxide and oxygen concentrations in the sub-shed 2 are continuously detected by the first detection unit. After a predetermined time, when the carbon dioxide and oxygen concentrations in the sub-shed 2 meet the second preset condition, the corresponding sub-shed 2 is opened to connect to the atmosphere, and the above steps are repeated to complete the exhaust gas purification work. The operating principles of different sub-sheds 2 are the same.

[0033] Therefore, the carbon emission absorption device of the present invention utilizes the photosynthesis of the plant 01 to absorb carbon, has a simple structure, is green and environmentally friendly, and accurately detects the oxygen and carbon dioxide concentrations in the sub-shed 2 through the first detection unit. On the one hand, the entire absorption process is accurate, controllable, and more practical; on the other hand, the carbon neutrality of the system can be accurately calculated, contributing to energy conservation, emission reduction, and green development in the whole society.

[0034] In this embodiment, the mother shed 1 and the sub-shed 2 are both made of transparent materials, such as transparent plastic, transparent glass, etc. The plant 01 performs photosynthesis, and the light source can be sunlight. A light source can also be provided inside the sub-shed 2 and / or the mother shed 1 to illuminate the corresponding plant 01, so that the plant 01 can also perform photosynthesis at night, or to supplement sunlight so that the plant 01 has the best lighting conditions; the plants 01 planted in different sub-sheds 2 can be different, and the sub-shed 2 is designed according to the characteristics of the plant 01 (crops); the setting of the mother shed 1 provides a suitable working environment for the staff.

[0035] In addition, the above-mentioned tail gas mainly includes carbon dioxide and non-combustible inert gas.

[0036] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the exhaust gas delivery pipeline 3 includes a main pipeline and branch pipelines connected to the sub-shed 2 in a one-to-one correspondence. The main pipeline is buried below the ground surface, and the branch pipelines extend upward to the inside of the sub-shed 2. This arrangement makes the overall structure of the device more neat and convenient.

[0037] Furthermore, the system further includes a condensing unit 5, a pressurizing unit 6, and a storage unit 7, which are sequentially arranged in the main pipeline. The tail gas is condensed and pressurized and stored in the storage unit 7. The condensing unit 5 can specifically be a heat exchange tube, etc., and the hot water generated after heat exchange can be used for other purposes.

[0038] A second detection unit and an adjustment unit are also provided inside the sub-shed 2. The second detection unit is used to detect the temperature and humidity conditions inside the sub-shed 2, and the adjustment unit is used to adjust the temperature and humidity inside the sub-shed 2. The temperature adjustment component can be an electric heating lamp, and the humidity adjustment can be achieved by spraying water.

[0039] In actual applications, the temperature and humidity conditions inside each sub-shed 2 also need to be adaptively adjusted according to the different plants 01 to be planted, so as to ensure that the plants 01 have optimal growth conditions.

[0040] In addition, the sub-shed 2 is opened to communicate with the atmosphere, which can be implemented in two ways:

[0041] In the first embodiment, a sidewall of sub-shed 2 is provided with an opening and a sealed door disposed at the opening, which can open and close the opening. When the carbon dioxide and oxygen concentrations in sub-shed 2 meet a second preset condition, the sealed door can be directly opened, allowing the exhaust gas in sub-shed 2 that meets the emission conditions to be discharged into main shed 1, which then releases it into the atmosphere.

[0042] A second embodiment further includes an output pipeline connecting sub-shed 2 and extending outside of main shed 1, and an induced draft fan connected to the outer end of the output pipeline. When the carbon dioxide and oxygen concentrations within sub-shed 2 meet a second preset condition, the exhaust gas meeting the discharge condition can be directly discharged to the atmosphere via the induced draft fan. Furthermore, a valve should be installed on the output pipeline and electrically connected to a controller. The controller opens the valve only when the discharge condition is met; otherwise, the valve closes, ensuring that sub-shed 2 remains sealed.

[0043] The present invention also provides a carbon emission absorption method, based on the aforementioned carbon emission absorption device, comprising the following steps:

[0044] Seal the sub-shed 2, introduce exhaust gas into the sub-shed 2, detect the carbon dioxide and oxygen concentrations inside the sub-shed 2, and close the corresponding valve when the carbon dioxide concentration in the sub-shed 2 meets a first preset condition;

[0045] The plant 01 performs photosynthesis and continuously detects the carbon dioxide concentration inside the sub-shed 2. When the carbon dioxide and oxygen concentrations inside the sub-shed 2 meet a second preset condition, the sub-shed 2 is opened to communicate with the atmosphere.

[0046] The carbon emission absorption method of the present invention is based on the aforementioned carbon emission absorption device and has the same technical effects as the aforementioned carbon emission absorption device, which will not be described in detail here.

Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The above examples are intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will be able to make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims.
