Description

Technical Field

[0001] This invention belongs to the technical field of carbon dioxide desorption equipment, and specifically relates to a desorption device for CO2 capture. Background Technology

[0002] Carbon dioxide is a colorless, tasteless, and odorless gas at room temperature. It is mainly emitted into the air through flue gas and exhaust emissions, and is one of the main components of greenhouse gases that gradually contribute to global warming. my country has many ways to reduce carbon dioxide emissions. Among them, reducing carbon emissions and achieving carbon neutrality is an important measure to address climate change and achieve sustainable human development. Carbon neutrality refers to calculating the amount of carbon dioxide emissions and offsetting the resulting carbon dioxide emissions through afforestation, energy conservation, and emission reduction, thereby achieving "zero emissions" of carbon dioxide.

[0003] The capture and desorption of carbon dioxide in flue gas is a technical process that separates carbon dioxide from the emission source by using a capture solvent in an absorption tower to absorb it at low temperature and desorb it at high temperature, thereby achieving carbon dioxide emission reduction.

[0004] Currently, most desorption equipment is used in flue gas emissions. However, without a corresponding pretreatment mechanism, impurities in the flue gas can easily enter the desorption equipment and combine with the collection solvent inside. This greatly increases solvent consumption. At the same time, the long-term accumulation of impurities also reduces the processing efficiency of the desorption equipment, affecting its subsequent use and causing the desorption equipment to be unable to fully capture CO2.

[0005] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a desorption device for CO2 capture. Summary of the Invention

[0006] To address the aforementioned problems, this invention solves the problem that impurities in the flue gas not only accelerate the consumption of the capturing solvent but also reduce the processing efficiency of the desorption equipment, resulting in the desorption equipment being unable to fully capture CO2.

[0038] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0039] like Figure 1 , Figure 9 A desorption device for CO2 capture includes: a desorption device body 1, a sedimentation pretreatment mechanism 2, a cutting-type efficiency-enhancing treatment mechanism 3, and a spraying-type efficiency-enhancing treatment mechanism 4.

[0040] A settling pretreatment mechanism 2 is connected to one side of the desorption device body 1 for purifying flue gas. The settling pretreatment mechanism 2 includes a settling treatment chamber 201, which facilitates the pretreatment of flue gas, enables the flue gas to be treated better, improves the efficiency of the desorption device body 1, and facilitates the containment of settling treatment water 202.

[0041] The settling treatment chamber 201 is equipped with settling treatment water 202, which can adsorb impurities in the flue gas. The impurities settle in the settling treatment water 202, which facilitates the collection of impurities.

[0042] In addition, a settling pressure chamber 203 is connected inside the settling treatment chamber 201, which facilitates the installation of the settling sliding chamber 204, improves the stability of the settling sliding chamber 204, and provides temporary storage space for flue gas.

[0043] The settling pressure chamber 203 is equipped with several evenly distributed settling sliding chambers 204. When the air pressure inside the settling pressure chamber 203 is sufficient, it can push out the settling sliding chambers 204 and make them slide.

[0044] refer to Figure 2 As shown, a settling injection pipe 205 is provided on one side of the settling treatment chamber 201, which facilitates the entry of flue gas into the settling treatment chamber 201, so that the flue gas can be purified through the settling treatment chamber 201, and facilitates the entry of flue gas into the settling pressure chamber 203.

[0045] The settling injection pipe 205 is set through the settling treatment chamber 201 and the settling pressure chamber 203, connecting the settling injection pipe 205 and the settling pressure chamber 203, so that the flue gas can enter the settling pressure chamber 203 better, increase the air pressure in the settling pressure chamber 203, and enable the air in the settling pressure chamber 203 to have enough power to drive the settling sliding chamber 204 to slide.

[0046] In addition, a settling support frame 206 is connected inside the settling air pressure chamber 203, which facilitates the installation of the settling pull spring 207, improves the stability of the settling pull spring 207, can fix the position of the settling pull spring 207, and provides a corresponding fulcrum for the settling pull spring 207, so that the settling pull spring 207 can be pulled when the settling sliding chamber 204 slides.

[0047] refer to Figure 2 As shown, a settlement support frame 206 and a settlement sliding chamber 204 are connected by a settlement pull spring 207, which can pull the settlement sliding chamber 204. When the air pressure in the settlement air pressure chamber 203 is too high, the settlement pull spring 207 can be pulled through the settlement sliding chamber 204, causing the settlement pull spring 207 to stretch.

[0048] In addition, the settling sliding chamber 204 is installed through the settling air pressure chamber 203 and can slide by air pressure, so that the settling sliding chamber 204 extends out of the settling air pressure chamber 203. Several discharge holes are drilled on the settling sliding chamber 204. When the settling sliding chamber 204 slides, the discharge holes are not blocked by the settling air pressure chamber 203, and the air in the settling air pressure chamber 203 can be discharged through the discharge holes.

[0049] refer to Figure 7 A pair of settling support blocks 208 are connected inside the settling treatment chamber 201, which can support the settling cleaning chamber 209, improve the stability of the settling cleaning chamber 209, enable the settling cleaning chamber 209 to slide, and reduce the probability of the settling cleaning chamber 209 tilting.

[0050] A settling cleaning chamber 209 is connected to a pair of settling support blocks 208, which can collect impurities and facilitate cleaning by sliding. The settling cleaning chamber 209 is set through the settling treatment chamber 201.

[0051] In addition, a sedimentation barrier net 210 is connected to the lower side of the sedimentation cleaning chamber 209, which facilitates the flow of sedimentation treatment water 202, can block impurities, does not obstruct the flow of sedimentation treatment water 202, facilitates the extraction of sedimentation treatment water 202 by spray treatment water pump 407, and reduces the possibility of spray treatment water pump 407 extracting impurities.

[0052] like Figure 7The settling cleaning chamber 209 has a screening groove that matches the settling barrier net 210, which facilitates the installation of the settling barrier net 210, improves the stability of the settling barrier net 210, reduces the probability of the settling barrier net 210 tilting, improves the balance of the settling barrier net 210, and enables the settling barrier net 210 to better bear impurities.

[0053] refer to Figure 3 As shown, a cutting-type efficiency-enhancing treatment mechanism 3 is connected inside the settling treatment chamber 201 to improve the purification effect of flue gas. The cutting-type efficiency-enhancing treatment mechanism 3 includes a cutting efficiency-enhancing frame 301, which can support the cutting efficiency-enhancing frame 302, reduce the probability of the cutting efficiency-enhancing frame 302 falling, improve the stability of the cutting efficiency-enhancing frame 302, and reduce the probability of the cutting efficiency-enhancing frame 302 tilting.

[0054] like Figure 6 The upper side of the cutting enhancement frame 301 is provided with a cutting enhancement frame 302, which facilitates the installation of the cutting enhancement mesh 303, improves the stability of the cutting enhancement mesh 303, and reduces the probability of deformation of the cutting enhancement mesh 303, thereby extending the service life of the cutting enhancement mesh 303.

[0055] In addition, a pair of cutting enhancement nets 303 are connected inside the cutting enhancement frame 302. When the cutting enhancement nets 303 vibrate, they can cut the air bubbles in the sedimentation water 202 and break them. When the air bubbles break, the impurities wrapped inside the air bubbles will be adsorbed by the sedimentation water 202 and settle into the sedimentation water 202.

[0056] In addition, the cutting enhancement frame 301 has a limiting groove that matches the cutting enhancement frame 302. When the cutting enhancement frame 302 vibrates, the cutting enhancement frame 301 can limit the position of the cutting enhancement frame 302, reducing the possibility of excessive vibration amplitude of the cutting enhancement frame 302, improving the stability of the cutting enhancement frame 302, and extending the service life of the cutting enhancement frame 302.

[0057] refer to Figure 6 As shown, a cutting enhancement airbag 304 is connected between the cutting enhancement frame 302 and the settling treatment chamber 201, which can buffer the cutting enhancement frame 302, improve the stability of the cutting enhancement frame 302, and extend the service life of the cutting enhancement frame 302.

[0058] like Figure 8The cutting enhancement block 305 is connected to the cutting enhancement frame 302, which facilitates the driving of the cutting enhancement cam 308 on the cutting enhancement frame 302, making the cutting enhancement frame 302 vibrate better, more controllable, and with a more stable vibration amplitude. Furthermore, the cutting enhancement block 305 is installed through the settling chamber 201, which facilitates the driving of the cutting enhancement cam 308 on the cutting enhancement block 305, reduces the loss of settling water 202, and improves sealing.

[0059] A cutting enhancement seal 306 is connected between the cutting enhancement block 305 and the settling treatment chamber 201, which improves the connection between the settling treatment chamber 201 and the cutting enhancement block 305, reduces the possibility of leakage of the settling treatment water 202 in the settling treatment chamber 201, and increases the service life of the settling treatment water 202 in the settling treatment chamber 201.

[0060] refer to Figure 3 As shown, a cutting efficiency motor 307 is connected to the settling treatment chamber 201, which can drive the rotation of the cutting efficiency cam 308, providing corresponding power for the rotation of the cutting efficiency cam 308, improving the controllability of the cutting efficiency cam 308, and improving the stability of the rotation of the cutting efficiency cam 308.

[0061] The cutting enhancement motor 307 is connected to a cutting enhancement cam 308, which can drive the cutting enhancement block 305 to shake through the shape of the cutting enhancement cam 308, so that the cutting enhancement block 305 can be driven better. The cutting enhancement block 305 has a driven groove that matches the cutting enhancement cam 308.

[0062] refer to Figure 4 As shown, a spray-type efficiency-enhancing treatment mechanism 4 is connected inside the settling treatment chamber 201 to further improve the purification effect of the flue gas. The spray-type efficiency-enhancing treatment mechanism 4 includes a spray treatment plate 401, which can divide the space inside the settling treatment chamber 201, allowing the space on the settling treatment chamber 201 to temporarily store the settling water 202. At the same time, it facilitates the installation of the spray treatment pipe 402, improves the stability of the spray treatment pipe 402, and enhances the balance of the spray treatment pipe 402.

[0063] like Figure 5 The spray treatment plate 401 is connected to a spray treatment pipe 402, which can be rotated by the spray treatment transmission belt 406. This allows the spray treatment pipe 402 to drive the spray treatment mesh bin 403, which facilitates the installation of the spray treatment mesh bin 403 and improves its stability.

[0064] In addition, the spray treatment pipe 402 is installed through the spray treatment plate 401, and the spray treatment pipe 402 is connected to the spray treatment mesh chamber 403, which can separate the sedimentation treatment water 202, so that the sedimentation treatment water 202 is better dispersed. Even if the bubbles contain a small amount of impurities, they can be settled through the sedimentation treatment water 202 in the spray treatment mesh chamber 403.

[0065] refer to Figure 4 As shown, a spraying motor 404 is connected to the settling treatment chamber 201, which can drive the rotation of the spraying treatment drive wheel 405 and provide corresponding power for the rotation of the spraying treatment drive wheel 405, making the rotation of the spraying treatment drive wheel 405 more controllable.

[0066] The spraying motor 404 is connected to a spraying drive wheel 405, which can drive the spraying pipeline 402 to rotate through the spraying drive belt 406.

[0067] In addition, a spraying drive belt 406 is connected between the spraying drive wheel 405 and the spraying pipe 402, which can play a transmission role, enabling the spraying drive wheel 405 to drive the rotation of the spraying pipe 402.

[0068] The spraying treatment drive belt 406 runs through the settling treatment chamber 201, which reduces the possibility of flue gas leakage in the settling treatment chamber 201 and improves the sealing performance of the settling treatment chamber 201.

[0069] In other words, a spray treatment water pump 407 is connected to one side of the sedimentation treatment chamber 201, which can extract the sedimentation treatment water 202 from the bottom of the sedimentation treatment chamber 201 and inject the sedimentation treatment water 202 into the spray treatment connecting pipe 408. The spray treatment water pump 407 and the sedimentation treatment chamber 201 are connected by the spray treatment connecting pipe 408, which connects the sedimentation treatment chamber 201 and the spray treatment water pump 407, so that the sedimentation treatment water 202 extracted by the spray treatment water pump 407 can be injected into the top of the sedimentation treatment chamber 201. Both the spray treatment water pump 407 and the spray treatment connecting pipe 408 are installed through the sedimentation treatment chamber 201.

[0070] Specifically, the user injects flue gas into the settling pressure chamber 203 through the settling injection pipe 205. When the flue gas in the settling pressure chamber 203 reaches a certain pressure, it will counteract the tension of the settling pull spring 207, causing the settling sliding chamber 204 to be pushed out. The flue gas then enters the settling treatment water 202 in the settling treatment chamber 201 through the discharge hole on the settling sliding chamber 204, where the settling treatment water 202 adsorbs impurities in the flue gas.

[0071] Some impurities are encased in bubbles and rise. The cutting efficiency motor 307 is activated, which causes the cutting efficiency cam 308 to drive the cutting efficiency block 305 to shake. The cutting efficiency frame 302 drives the cutting efficiency mesh 303 to vibrate synchronously. The cutting efficiency mesh 303 can cut the bubbles, greatly reducing the possibility of impurities in the bubbles floating to the surface, and allowing the impurities in the bubbles to be adsorbed by the sedimentation treatment water 202.

[0072] Meanwhile, the spray treatment water pump 407 draws the sedimentation treatment water 202 from the bottom of the sedimentation treatment chamber 201 and injects it onto the spray treatment plate 401. The sedimentation treatment water 202 enters the spray treatment mesh chamber 403. Through the combined action of water pressure and the spray treatment mesh chamber 403, mist is generated, causing impurities in the air to settle. Finally, the impurities fall into the sedimentation cleaning chamber 209. Users can clean the sedimentation cleaning chamber 209 at any time by sliding it.

[0073] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
