Description

Technical Field

[0001] This application relates to the field of carbon neutrality and recycling technology, and more specifically, to a carbon neutrality and recycling device. Background Technology

[0002] In existing industrial production processes, carbon neutralization is achieved through chemical absorption of emitted carbon dioxide, and carbon dioxide is fully utilized to reduce emissions and mitigate the greenhouse effect.

[0003] For example, the production process of cement products releases a large amount of carbon dioxide. Enterprises usually use alkaline solutions, such as calcium oxide solutions, to react with the emitted carbon dioxide at high temperatures to produce calcium carbonate, thereby capturing the carbon dioxide and reusing it in the future, thus reducing carbon dioxide emissions.

[0004] However, during the capture of carbon dioxide, the calcium oxide in the alkaline solution gradually decreases due to the chemical reaction with carbon dioxide, and a solid precipitate (calcium carbonate) is also generated. If the alkaline solution in the reaction device is not replenished in time and the solid precipitate is not discharged, the capture efficiency of the entire reaction device for carbon dioxide will be affected. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a carbon neutralization and recovery device, which aims to improve the problem that existing carbon neutralization and recovery devices are inconvenient to replenish alkaline solution in a timely manner during the capture of carbon dioxide and to promptly discharge precipitates generated during the chemical reaction, thus affecting the efficiency of carbon dioxide neutralization and recovery.

[0006] This application proposes a carbon neutrality recovery and utilization device, comprising: a raw liquid tank, a reaction tank, an overflow tank, and an aeration assembly. The raw liquid tank is configured with two layers, wherein the top of the outer layer is higher than the top of the inner layer, and the bottom of the outer layer is higher than the bottom of the inner layer. The raw liquid tank is coaxially fixed to the bottom of the inner layer, and the top of the outer layer of the raw liquid tank is higher than the top of the reaction tank. The outer layer of the raw liquid tank is in communication with the reaction tank. The overflow tank is coaxially sleeved on the outside of the top of the reaction tank, and the overflow tank is in communication with the reaction tank. The aeration assembly is coaxially disposed between the raw liquid tank and the reaction tank, and the aeration assembly is connected to an air supply device.

[0007] According to an embodiment of this application, a carbon neutralization and recovery device has the following advantages: The double-layer design of the raw liquid tank allows for a continuous supply of saturated alkaline solution to the reaction chamber, preventing the depletion of the alkaline solution inside the reaction chamber from affecting the carbon dioxide neutralization and recovery efficiency. Simultaneously, the overflow tank allows for the discharge of the alkaline solution consumed in the reaction chamber, ensuring a continuous renewal of the alkaline solution within the reaction chamber with the help of the replenishment from the raw liquid tank. Furthermore, the rotation of the aeration components further enhances the chemical reaction within the reaction chamber, improving the carbon dioxide neutralization and capture efficiency. The pipes connecting the bottom of the raw liquid tank and the reaction chamber allow for timely discharge of any precipitates, preventing any impact on the carbon dioxide neutralization reaction.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figures 1-5 As shown, a carbon neutralization and recycling device according to an embodiment of this application includes a raw liquid tank 1. The raw liquid tank 1 is configured with two layers, wherein the height of the top of the outer layer is higher than the height of the top of the inner layer, and the height of the bottom of the outer layer is higher than the height of the bottom of the inner layer.

[0025] Specifically, such as Figures 1-3As shown, the bottom of the raw liquid tank 1 is connected to a bottom suction pipe 11, and the outside of the raw liquid tank 1 is a replenishment tank 12. Multiple replenishment ports 121 are evenly arranged around the bottom of the replenishment tank 12.

[0026] Therefore, in actual use, the inner layer of the original liquid tank 1 stores a saturated alkaline solution. The saturated alkaline solution can be transported into the inner layer of the original liquid tank 1 through an external infusion device. Alternatively, water can be directly injected into the inner layer of the original liquid tank 1, and then quicklime (calcium oxide) can be added. The quicklime and water will react chemically to produce calcium hydroxide, namely CaO + H2O = Ca(OH)2. This will then form two layers of solution in the original liquid tank 1. The upper layer is clear lime water, and the lower layer is a suspension of lime milk or lime slurry. As the solution increases, it will overflow from the upper part of the inner layer to the inner layer of the replenishment tank 12, and enter the interior of the reaction tank 2 through the replenishment port 121.

[0027] like Figures 1-4 The reaction chamber 2 shown has the original liquid chamber 1 coaxially fixed to the bottom of the original liquid chamber 1. The height of the top of the outer layer of the original liquid chamber 1 is higher than the height of the top of the reaction chamber 2. The outer layer of the original liquid chamber 1 is connected to the reaction chamber 2. This is to prevent the solution in the reaction chamber 2 from flowing back into the replenishment tank 12, which would cause a decrease in the concentration of the saturated alkaline solution provided by the replenishment tank 12 to the reaction chamber 2, thus affecting the subsequent chemical reaction.

[0028] Specifically, the interior of reaction chamber 2 is connected to a gas supply pipe 21 and a slag discharge pipe 22. The gas supply pipe 21 is connected to the aeration component 4, supplying carbon dioxide gas to the aeration component 4. The inlet end of the slag discharge pipe 22 is located at the bottom of the reaction chamber 2, facilitating the timely removal of sediment formed at the bottom of the reaction chamber 2. Multiple overflow ports 23 are evenly arranged circumferentially on the side wall of reaction chamber 2, and these overflow ports 23 are connected to overflow chamber 3. It can be understood that as the replenishment tank 12 continuously replenishes the reaction chamber 2 with saturated alkaline solution, the liquid level inside the reaction chamber 2 will gradually increase. Once the increased liquid reaches the overflow port 23, it will enter the overflow chamber 3 from the overflow port 23 and be discharged. In this way, the alkaline solution in the reaction chamber 2 will be constantly renewed, preventing the concentration of the alkaline solution from becoming insufficient as the chemical reaction proceeds, which would affect the neutralization of carbon dioxide, i.e., Ca(OH)2 + CO2 = CaCO3 + H2O.

[0029] like Figure 1 , Figure 2 and Figure 4 The overflow chamber 3 shown is coaxially sleeved on the outside of the top of the reaction chamber 2, and the overflow chamber 3 is connected to the reaction chamber 2. It is used to discharge the solution overflowing from the reaction chamber 2 in a timely manner to prevent the liquid level inside the reaction chamber 2 from gradually increasing and flowing back into the replenishment chamber 12.

[0030] like Figure 2 , Figure 4 and Figure 5 The aeration component 4 shown is coaxially positioned between the raw liquid chamber 1 and the reaction chamber 2. The aeration component 4 is connected to the air supply device, namely the air supply pipe 21 mentioned above.

[0031] Specifically, the aeration assembly 4 includes: a base plate 41, a rotating chamber 42, and a support member 43. The base plate 41 is arranged in a ring shape and is fitted onto the exhaust end of the gas supply pipe 21. Multiple air nozzles are evenly connected to the base plate 41 in a circumferential direction to facilitate the uniform supply of carbon dioxide gas into the reaction chamber 2. The rotating chamber 42 is sealed and rotatably connected to the base plate 41. The support member 43 is fixedly connected to the base plate 41 and the original liquid chamber 1 respectively.

[0032] Multiple power plates 421 are uniformly fixed to the inner top circumference of the rotating chamber 42. The power plates 421 are inclined, and a guide groove 422 is opened in the center of the power plate 421. Therefore, when the air supply pipe 21 supplies air into the rotating chamber 42, the airflow impact will generate rotational power for the power plates 421, thus causing the entire rotating chamber 42 to rotate on the base plate 41. The guide groove 422 in the middle of the power plate 421, together with the rotating chamber 42, will make the gas in the entire aeration component 4 evenly distributed, thus further enhancing the exhaust at multiple air heads. The uniformity of the airflow and the rotating chamber 42 also have a certain effect of stirring the solution inside the reaction chamber 2, further enhancing the reaction efficiency between the solution and carbon dioxide. It should also be noted that, in the specific embodiment of this application, the liquid replenishment port 121 is preferably set on the upper side of the rotating chamber 42, so as to facilitate the timely mixing of the saturated solution and the solution inside the reaction chamber 2. At the same time, the top of the rotating chamber 42 adopts an inclined design that gradually descends from the inside to the outside, which can further improve the mixing effect and also prevent the accumulation of sediment at the top of the rotating chamber 42.

[0033] In a specific embodiment of this application, the support member 43 consists of a support ring 431 fixedly sleeved on the outer wall of the original liquid tank 1, and a plurality of support strips 432 uniformly fixed to the outside of the support ring 431, so as to provide support for the bottom plate 41.

[0034] It should be further noted that a filter screen 5 is provided on the bottom side of the aeration component 4. The filter screen 5 is detachably fixed to the raw liquid tank 1 and the reaction tank 2. The filter screen 5 can reduce the agitation of the solution below the bottom plate 41 to a certain extent, which helps the precipitate formed during the chemical reaction to form a better precipitate at the bottom of the reaction tank 2, and helps the slag discharge pipe 22 to extract the precipitate in a timely manner.

[0035] This design allows carbon dioxide generated during the production process to be continuously neutralized and recovered within the device of this application, thereby improving the neutralization and recovery efficiency of carbon dioxide.

[0036] It should be noted that the specific model and specifications of filter 5 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
