[0002] With the acceleration of global industrialization, the emission of waste gases such as carbon dioxide generated in industrial production is increasing day by day, causing serious impact on the environment. The large amount of direct carbon dioxide emissions not only wastes precious carbon resources, but also accelerates the speed of global warming, bringing huge challenges to humans and ecosystems.

[0003] Although the existing carbon dioxide recovery devices have achieved carbon dioxide recovery to a certain extent, in actual applications, since there is still a large amount of heat energy in the exhaust gas when it is discharged, many devices fail to fully utilize the heat energy in the exhaust gas, resulting in a large amount of energy waste. In addition, the traditional design often makes filter replacement and cleaning complicated and cumbersome, which increases the difficulty and cost of maintenance and affects applicability.

[0026] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model.

[0027] like Figure 1-6 As shown, a carbon dioxide waste gas recovery device that is beneficial to pollution reduction and carbon reduction includes a body 10, the body 10 includes an air intake pipe 11, the left side of the air intake pipe 11 is connected to a main body 12, the top of the main body 12 is connected to a filter assembly 13, and the left side of the main body 12 is connected to an exhaust pipe 14:

[0028] The heat exchange assembly 20 includes a tube group 21 connected to the inner cavity of the air inlet pipe 11, a heat storage tank 22 is fixedly connected to the front of the main body 12, and a discharge port 23 is opened at the bottom of the front of the heat storage tank 22;

[0029] A carbon dioxide recovery component 30, the carbon dioxide recovery component 30 comprises an adsorption component 31 slidably connected to the inner cavity of the main body 12, and a driving component 32 is fixedly connected to the front of the main body 12;

[0030] After the adsorption component 31 adsorbs carbon dioxide, the driving component 32 drives the adsorption component 31 to move outward along the inner cavity of the heat storage tank 22, and the pipe group 21 is used to adsorb the heat in the intake pipe 11 and precipitate the carbon dioxide through the heat.

[0031] It should be noted that the portion where the main body 12 contacts the filter assembly 13 is provided with a sealing structure to prevent the exhaust gas from leaking out;

[0032] The exhaust port 23 can be connected to an external exhaust component such as an air pump or a pipeline, which is not limited here, and is intended to discharge and collect the desorbed carbon dioxide.

[0033] In this embodiment, after the exhaust gas enters the main body 12 through the intake pipe 11, the dust and moisture are first filtered through the filter assembly 13, and the carbon dioxide will be adsorbed by the adsorption assembly 31. When the filter assembly 13 needs to be removed, the filter assembly 13 can be quickly removed through the fixed parts of the movable filter assembly 13. When the device is running, the cold material will flow in the pipe group 21, and absorb the heat of the exhaust gas in the intake pipe 11, and send it into the heat storage box 22 for heat storage. At the same time, the driving assembly 32 will drive the adsorption assembly 31 into the heat storage box 22, desorb the carbon dioxide by heat, and discharge it from the exhaust port 23.

[0034] like Figure 2-4 As shown, the filter assembly 13 includes a filter 131 movably inserted into the top of the main body 12, a fixing groove 132 is provided at the top of the left side of the filter 131, a fixing block 133 is slidably connected to the top inner cavity of the main body 12, a spring 134 is fixedly connected to the left side of the fixing block 133, and the left end of the spring 134 is fixedly connected to the inner cavity of the main body 12.

[0035] It should be noted that a pushing plate is provided on the top of the fixed block 133, and the plate is slidably connected to the top of the main body 12. Importantly, a slope is provided on the top surface of the fixed block 133, so that when the filter 131 is pressed down, the fixed block 133 can be pushed into the main body 12 by the force of the slope to avoid affecting the insertion of the filter 131.

[0036] In this embodiment, when installing the filter 131, the filter 131 is directly inserted into the main body 12. During the insertion of the filter 131, the slope on the top surface of the fixing block 133 is squeezed, and the fixing block 133 is pushed into the main body 12 by the force of the slope. After the filter 131 is fully inserted, the fixing groove 132 is aligned with the fixing block 133. At this time, the spring 134 rebounds quickly, pushing the fixing block 133 into the fixing groove 132 to fix the filter 131.

[0037] When disassembling, it is only necessary to push the push plate on the top of the fixing block 133 to store it in the main body 12, and then directly pull the handle on the top of the filter screen 131 to pull it out.

[0038] like Figure 2 , Figure 5-6As shown, the tube group 21 includes a heat absorbing tube 211 fixedly connected to the inner cavity of the air inlet pipe 11, the top inlet of the heat absorbing tube 211 is connected to the feed tube 212, the inner cavity of the heat storage tank 22 is fixedly connected to a heat conducting tube 213, the top inlet of the heat conducting tube 213 is connected to the outlet of the heat absorbing tube 211, and the left outlet of the heat conducting tube 213 is connected to the discharge tube 214;

[0039] The adsorption assembly 31 includes an adsorption plate 311 slidably connected to the inner cavity of the main body 12, and a sliding rod 312 is fixedly connected to the front of the adsorption plate 311, and the sliding rod 312 is slidably connected to the middle part of the heat storage tank 22;

[0040] The driving assembly 32 includes an electric push rod 321 fixedly connected to the front of the main body 12, a driving plate 322 is fixedly connected to the front top of the electric push rod 321, and the middle part of the driving plate 322 is fixedly connected to the front top of the sliding rod 312;

[0041] The adsorption plate 311 uses nanoporous material as an adsorbent.

[0042] It should be noted that the pipe connecting the heat absorbing pipe 211 and the heat conducting pipe 213 is a heat-insulating pipe, such as a heat-insulating pipe, etc., which is not limited here, and is intended to reduce heat loss;

[0043] The portion where the outer circle of the adsorption plate 311 contacts the main body 12 is provided with a sealing strip, which is intended to prevent the carbon dioxide from flowing back into the main body 12 and causing resource loss when the adsorption plate 311 desorbs carbon dioxide.

[0044] In this embodiment, when the device is running, the cold material will enter the feed pipe 212 and flow into the heat absorption pipe 211, and absorb the heat of the exhaust gas in the intake pipe 11 through the heat absorption pipe 211. The cold material that absorbs the heat will flow into the heat conduction pipe 213, and continuously transfer the absorbed heat to the heat storage tank 22, and the cold material that dissipates the heat will be discharged through the discharge pipe 214. After the adsorption plate 311 adsorbs carbon dioxide, the electric push rod 321 pushes the drive plate 322 to move, pulls the slide bar 312 and the adsorption plate 311 to move, and sends the adsorption plate 311 into the heat storage tank 22. After the adsorption plate 311 enters the heat storage tank 22, the heat will be transferred to the adsorption plate 311, and the adsorbed carbon dioxide will be desorbed by the heat and discharged through the discharge port 23.

[0045] The working principle of the utility model is as follows: after the exhaust gas enters the main body 12 through the intake pipe 11, the dust and water vapor are first filtered through the filter screen 131, and the carbon dioxide will be adsorbed by the adsorption plate 311. When the device is running, the cold material will enter the feed pipe 212 and flow into the heat absorption pipe 211, and absorb the heat of the exhaust gas in the intake pipe 11 through the heat absorption pipe 211. The heat-absorbing cold material will flow into the heat conduction pipe 213 and continuously transfer the absorbed heat to the heat storage tank 22, and the heat-dissipating cold material will be discharged through the discharge pipe 214. After the adsorption plate 311 adsorbs carbon dioxide, the electric The push rod 321 pushes the driving plate 322 to move, pulls the sliding rod 312 and the adsorption plate 311 to move, and sends the adsorption plate 311 into the heat storage tank 22. After the adsorption plate 311 enters the heat storage tank 22, the heat will be transferred to the adsorption plate 311, and the adsorbed carbon dioxide will be desorbed by the heat and discharged through the discharge port 23. When the filter 131 needs to be disassembled for cleaning after the operation is completed, it is only necessary to push the pushing plate on the top of the fixing block 133 to put it into the main body 12 and disengage it from the fixing groove 132, and then directly pull the handle on the top of the filter 131 to pull it out.

[0046] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be regarded as the protection scope of this utility model. The structures, devices and operating methods not specifically described and explained in this utility model shall be implemented according to the conventional means in this field unless otherwise specified and limited.
