[0032] Embodiment 1:

[0033] As Figure 1 shown, a dual - duct device for simultaneously adsorbing and desorbing carbon dioxide includes:

[0034] A housing 1; an intake pipe 2, a first outlet pipe 8, and a second outlet pipe 9 that communicate the inside and outside of the housing 1 are provided on the housing 1. The ends of the intake pipe 2, the first outlet pipe 8, and the second outlet pipe 9 facing the inside of the housing 1 are all first ends, and the ends facing the outside of the housing 1 are all second ends;

[0035] Two dual - duct units; the dual - duct units are arranged inside the housing 1. One dual - duct unit includes a temperature control component and a unit housing 4. A first chamber and a second chamber that do not communicate with each other are provided inside one unit housing 4. The two ends of the first chamber of each dual - duct unit are respectively communicated with the first end of the intake pipe 2 and the first end of the first outlet pipe 8, and the two ends of the second chamber of each dual - duct unit are respectively communicated with the first end of the intake pipe 2 and the first end of the second outlet pipe 9. The temperature control component is used to control the temperatures inside the first chamber and the second chamber respectively;

[0036] Four fans; the fans are all arranged inside the housing 1, and the fans are used to accelerate the air flowing through the first chamber and the second chamber;

[0037] Carbon dioxide adsorption material 5; The first chamber and the second chamber are both filled with the carbon dioxide adsorption material 5. When the carbon dioxide adsorption material 5 is not heated, the carbon dioxide adsorption material 5 adsorbs carbon dioxide in the air. When the carbon dioxide adsorption material 5 is heated, the carbon dioxide adsorption material 5 releases the adsorbed carbon dioxide;

[0038] Control switch; Both the fan and the temperature control component are connected to the control switch.

[0039] In this embodiment, the present application is provided with a double air duct unit. The temperature of the carbon dioxide adsorption material 5 in the first chamber and the second chamber can be controlled by the temperature control component, so as to control the first chamber and the second chamber to perform carbon dioxide adsorption operations or carbon dioxide release operations respectively. And the first chamber and the second chamber are respectively connected to a first air outlet pipe 8 and a second air outlet pipe 9;

[0040] When the temperature control component controls the first chamber to perform a carbon dioxide adsorption operation and the second chamber to perform a carbon dioxide release operation, the output gas of the first air outlet pipe 8 is air containing low-concentration carbon dioxide. At this time, the first air outlet pipe 8 can be connected to a place that requires air containing low-concentration carbon dioxide, such as an airtight place such as a gymnasium, a classroom, a concert hall, and a car interior. The output gas of the second air outlet pipe 9 is air containing high-concentration carbon dioxide. At this time, the second air outlet pipe 9 can be connected to a place that requires air containing high-concentration carbon dioxide, such as a carbon-rich environment cultivation place for plants, or stored using a gas collecting bottle. When the carbon dioxide adsorption material 5 in the first chamber and the second chamber reaches the adsorption threshold or the release threshold, the temperature control component controls the first chamber to perform a carbon dioxide release operation to release the just-adsorbed carbon dioxide, and the second chamber performs a carbon dioxide adsorption operation to re-adsorb the carbon dioxide. At this time, the connection places of the first air outlet pipe 8 and the second air outlet pipe 9 are exchanged.

[0041] The present application can simultaneously and continuously perform the adsorption and release of carbon dioxide, and respectively transport air containing low-concentration carbon dioxide and air containing high-concentration carbon dioxide to the demand scenarios, making the most of the air, without waste gas and tail gas and other products, and having high working efficiency, which can meet the different carbon dioxide concentration requirements of various places.

[0042] Embodiment 2:

[0043] The difference between this embodiment and Embodiment 1 is that, as Figure 1 shown, the temperature control component is a temperature control chip 6. The temperature control chip 6 is arranged in the unit housing 4. The temperature control chip 6 divides the unit housing 4 into a first chamber and a second chamber that do not communicate with each other. When the temperature control chip 6 is powered on, the first side and the second side of the temperature control chip 6 perform refrigeration and heating respectively. When the current direction is reversed, the first side and the second side of the temperature control chip 6 perform heating and refrigeration respectively.

[0044] In this embodiment, by directly contacting the temperature control sheet 6 with the carbon dioxide adsorption material 5, the temperature conversion efficiency can be improved, and the characteristic of opposite temperatures on both sides of the temperature control sheet 6 can increase the conversion speed and operation efficiency of this application.

[0045] Embodiment 3:

[0046] The difference between this embodiment and Embodiment 1 is that the carbon dioxide adsorption material 5 is granular, and there are gaps for air circulation left between the carbon dioxide adsorption material 5 particles in the first chamber and the second chamber.

[0047] In this embodiment, the carbon dioxide adsorption material 5 is a DAC technology material, such as the carbon dioxide capture material for mosquito trapping equipment involved in the patent with the patent number ZL202410482343.X.

[0048] Embodiment 4:

[0049] The difference between this embodiment and Embodiment 1 is that, as Figure 1 shown, the double air duct device further includes four intake connection pipes 3 and four outlet connection pipes 7. The first end of one first chamber and the first end of one second chamber are respectively communicated with the first ends of two intake connection pipes 3. The second ends of the intake connection pipes 3 are all communicated with the first end of the intake pipe 2. The second ends of one first chamber and one second chamber are respectively communicated with the first ends of two outlet connection pipes 7. The second end of the outlet connection pipe 7 communicated with the first chamber is communicated with the first end of the first outlet pipe 8. The second end of the outlet connection pipe 7 communicated with the second chamber is communicated with the first end of the second outlet pipe 9.

[0050] In this embodiment, a fan is installed in one outlet connection pipe 7, and each fan is connected to a control switch. When only one double air duct unit needs to operate, only the fan in the outlet connection pipe 7 connected to this double air duct unit needs to be turned on. At this time, due to the air pressure difference, most of the air will not flow through the other double air duct unit where the fan is not turned on. By combining the control switch and the fan, the adsorption efficiency of this application can be adjusted to adapt to more operation scenarios.

[0051] Embodiment 5:

[0052] The difference between this embodiment and Embodiment 1 is that, as Figure 1 and Figure 2 shown, the double air duct device further includes a shunt pipe 10. The shunt pipe 10 includes:

[0053] a pipe body 12;

[0054] a first branch pipe 11; both ends of the first branch pipe 11 are respectively communicated with one side of the pipe body 12 and the second end of the first outlet pipe 8;

[0055] The second branch pipe 14; both ends of the second branch pipe 14 are respectively communicated with the other side of the pipe body 12 and the second end of the second air outlet pipe 9;

[0056] The driving motor; the driving motor is connected to the control switch;

[0057] The reversing baffle 13; the rotating shaft of the driving motor passes through the pipe body 12 and is connected to the reversing baffle 13. When the first end and the second end of the reversing baffle 13 are respectively attached to the first inner side wall and the second inner side wall of the pipe body 12, the pipe body 12 is divided into two non-communicating first part and second part. At this time, the first part is communicated with the first branch pipe 11, and the second part is communicated with the second branch pipe 14. When the driving motor drives the first end and the second end of the reversing baffle 13 to be respectively attached to the second inner side wall and the first inner side wall of the pipe body 12, the first part is communicated with the second branch pipe 14, and the second part is communicated with the first branch pipe 11.

[0058] In this embodiment, both ends of the pipe body 12 of the shunt pipe 10 can be communicated with the required place for a long time or permanently. When switching between the adsorption and release operations, only by controlling the driving motor to rotate accordingly, one end of the pipe body 12 can be permanently communicated with the air outlet pipe containing high-concentration carbon dioxide air, and the other end can be permanently communicated with the air outlet pipe containing low-concentration carbon dioxide air, thus eliminating the switching time of switching the first air outlet pipe 8 and the second air outlet pipe 9 and improving the working efficiency.

[0059] Embodiment 6:

[0060] The difference between this embodiment and Embodiment 3 is that the temperature control piece 6 adopts a semiconductor PTC temperature control piece.

[0061] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
