Description

Technical Field

[0001] This utility model belongs to the technical field of carbon dioxide recovery devices, specifically relating to an integrated device for dual-carbon governance, carbon capture, recovery, and reuse. Background Technology

[0002] Since the Industrial Revolution, the large amount of waste gas produced by the burning of fossil fuels has led to a sharp increase in the concentration of carbon dioxide in the atmosphere. The significantly increased carbon dioxide emissions are one of the main factors causing medium- and long-term global climate change. Existing coal-fired power plants use fossil fuels, and the flue gas released after combustion contains a large amount of carbon dioxide. Direct emissions will exacerbate the greenhouse effect and greatly damage the environment, which is inconsistent with the goal of dual carbon governance.

[0003] The existing announcement number CN221846626U, entitled "A Carbon Dioxide Capture, Recycling, and Reuse Mechanism," includes a capture tank, a storage tank fixedly connected to the top of the capture tank, a water pump fixedly installed inside the storage tank, a fixed chamber fixedly connected to the right side of the capture tank, two diversion pipes rotatably connected to the right side of the capture tank, and multiple nozzles fixedly connected to the bottom of the diversion pipes. The capture tank is equipped with an agitator, and the fixed chamber is equipped with an adjustment mechanism. This carbon dioxide capture, recycling, and reuse mechanism, through the adjustment mechanism, allows for the movement of a toothed plate up and down by activating a second motor during the carbon dioxide capture and recycling process. This causes the diversion pipes to rotate in both directions, and the oscillating nozzles expand the spray range, enabling the absorbent to fully absorb carbon dioxide, thereby improving the carbon dioxide separation, capture, and recycling efficiency and facilitating subsequent reuse of carbon dioxide.

[0004] The above-mentioned method for recovering carbon dioxide from flue gas uses a diverter to spray a recovery reagent into the flue gas for carbon dioxide recovery. However, in actual use, the flue gas is guided into the capture tank and the diverter sprays the recovery reagent from top to bottom. As the recovery reagent settles downwards, it comes into contact with the carbon dioxide in the flue gas and is reacted and consumed. As a result, the carbon dioxide in the flue gas at the bottom of the capture tank cannot fully contact the recovery reagent, which in turn affects the uniformity and completeness of carbon dioxide recovery from the flue gas. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an integrated device for dual carbon treatment, carbon capture, recycling and reuse, which can achieve full contact between the flue gas flowing in opposite directions and the solvent used for carbon dioxide recovery in the recovery solution, thereby improving the fullness and uniformity of carbon dioxide recovery in the flue gas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated device for dual-carbon governance, carbon capture, recycling and reuse, comprising a support, a recovery tank, a heating tank and a pressurized reaction tank, wherein multiple recovery tanks are vertically fixed on the upper part of the support along the horizontal direction, and a heating tank and a pressurized reaction tank are vertically fixed on the lower part of the support along the horizontal direction respectively.

[0007] Multiple recovery tanks are connected and fixed at their top with an inlet diversion pipe, and the top of the inlet diversion pipe is used to connect to the reaction solution pipeline. Multiple recovery tanks are connected and fixed at their bottom with a drain diversion pipe, and the bottom of the drain diversion pipe is connected and fixed to the top of the heating tank. Multiple recovery tanks are connected and fixed at their bottom outer circumference with a smoke inlet diversion pipe, and the end of the smoke inlet diversion pipe is connected to a filter assembly. Multiple recovery tanks are connected and fixed at their top outer circumference with a smoke exhaust diversion pipe, and the exhaust end of the smoke exhaust diversion pipe is connected to the smoke exhaust pipeline.

[0008] The top of the heating tank is connected and fixed to the bottom of the drain pipe, and the bottom of the heating tank is connected and fixed to the drain pipe. Valves are also connected and fixed to both the bottom of the drain pipe and the drain pipe.

[0009] The top of the pressurized reaction tank is connected to and fixed to the top of the heating tank via a pipe, and the bottom of the pressurized reaction tank is connected to and fixed to a discharge pipe. An ammonia inlet pipe is connected to and fixed to the top of the pressurized reaction tank, and the end of the ammonia inlet pipe is connected to and fixed to an ammonia delivery pipe. Valves are connected to and fixed to the discharge pipe and the pipe between the pressurized reaction tank and the heating tank.

[0010] Furthermore, the filter element includes a filter box, on which two symmetrical vertical end faces are horizontally connected and fixed with spiral tubes, and two sliding frames are symmetrically and vertically arranged inside the filter box, with filter screens vertically fixed on the inner walls of the two sliding frames.

[0011] Furthermore, the inner walls of the filter box are symmetrically fixed with sliding strips on both the upper and lower sides, and the sliding strips are slidably assembled and connected to the sliding frame.

[0012] Furthermore, a screw housing is fixed horizontally at the end of the smoke inlet diversion pipe.

[0013] Furthermore, the spiral tube on one side of the filter box is connected to the flue and assembled, and the spiral tube on the other side of the filter box is connected to the threaded assembly of the screw shell on the flue gas diversion pipe.

[0014] Furthermore, the bottom surface of the filter box is symmetrically provided with through slots, and a ash storage box is inserted into the through slots of the filter box. The top of the ash storage box is open, and a magnetic strip is horizontally fixed on the outside of the ash storage box, and the magnetic strip is magnetically connected to the bottom surface of the filter box.

[0015] Furthermore, a motor is fixed through the center of the bottom surface of the filter box, and a cam is horizontally fixed at the output end of the motor.

[0016] Furthermore, a spring is horizontally fixed on one vertical end face of the sliding frame, and the other end of the spring is fixed on the inner wall of the filter box.

[0017] Furthermore, a fixing screw is horizontally fixed on the rear end face of the bracket.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] First, the flue gas is dispersed and guided to multiple recovery tanks through the flue gas inlet diversion pipe. This dispersed flue gas is used for carbon dioxide recovery, reducing the volume of flue gas recovery and facilitating the uniformity of carbon dioxide recovery. The recovery solution, such as amine solution, used to recover carbon dioxide from the flue gas is dispersed and guided to multiple recovery tanks through the liquid inlet diversion pipe. The recovery solution flows from top to bottom in the multiple recovery tanks, while the flue gas guided into the recovery tanks moves from bottom to top. Then, the flue gas with recovered carbon dioxide is discharged into the flue through the exhaust diversion pipe at the top of the multiple recovery tanks. The recovered solution that falls down is collected from the drain diversion pipe and flows into the heating tank, completing the recovery of carbon dioxide from the flue gas.

[0020] Secondly, in order to extract carbon dioxide from the recovery solution, the bottom end of the drain pipe and the valve on the drain pipe are closed, and the recovery solution is heated in the heating tank, causing carbon dioxide to overflow from the recovery solution.

[0021] In addition, carbon dioxide in the heating tank is piped into the pressurized reaction tank. The valve on the pipe between the pressurized reaction tank and the heating tank is closed. At the same time, ammonia is piped into the pressurized reaction tank. Carbon dioxide and ammonia react under high pressure and high temperature conditions in the pressurized reaction tank to form urea, which is a carbon dioxide that can be reused and recovered later.

[0022] In summary, this invention improves the completeness and uniformity of carbon dioxide recovery in flue gas by ensuring full contact between the opposing flow of flue gas and the solvent used for carbon dioxide recovery in the recovery solution. Attached Figure Description

[0034] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0035] refer to Figures 1-5 As shown, an integrated device for dual-carbon governance, carbon capture, recycling, and reuse includes a support 1, a recovery tank 2, a heating tank 3, and a pressurized reaction tank 4. Multiple recovery tanks 2 are vertically fixed in the upper part of the support 1 along the horizontal direction, and the heating tank 3 and the pressurized reaction tank 4 are vertically fixed in the lower part of the support 1 along the horizontal direction. Fixing screws 11 are horizontally fixed on the rear end face of the support 1. The support 1 supports multiple recovery tanks 2, heating tanks 3, and pressurized reaction tanks 4 to form a whole. The fixing screws 11 on the support 1 are used to lock and fix the support 1 to ensure the stability of the installation.

[0036] Multiple recovery tanks 2 are connected and fixed to the top of an inlet diversion pipe 21, the top of which is used to connect to a reaction solution pipeline. Multiple recovery tanks 2 are connected and fixed to the bottom of an outlet diversion pipe 22, the bottom of which is connected and fixed to the top of a heating tank 3. Multiple recovery tanks 2 are horizontally connected and fixed to the bottom of their outer circumference via an inlet diversion pipe 23, the end of which is connected to a filter element 5. Multiple recovery tanks 2 are horizontally connected and fixed to the top of their outer circumference via an outlet diversion pipe 24, the outlet of which is connected to an exhaust pipeline. During use, flue gas is dispersed and guided to multiple recovery tanks 2 through the inlet diversion pipe 23 to disperse the flue gas for carbon dioxide recovery, reducing the time required for flue gas recovery. The capacity facilitates the uniformity of carbon dioxide recovery from flue gas. The recovery solution, such as amine solution, used to recover carbon dioxide from the flue gas is dispersed and guided to multiple recovery tanks 2 through the liquid inlet diversion pipe 21. The recovery solution flows from top to bottom in the multiple recovery tanks 2, while the flue gas guided into the recovery tanks 2 moves from bottom to top. This ensures that the flue gas flowing in opposite directions and the solvent used to recover carbon dioxide in the recovery solution are in full contact, improving the fullness and uniformity of carbon dioxide recovery from the flue gas. Then, the flue gas with recovered carbon dioxide is discharged into the flue from the exhaust diversion pipe 24 at the top of the multiple recovery tanks 2. The recovered solution that falls down is collected and flows down from the liquid outlet diversion pipe 22 and enters the heating tank 3, thus completing the recovery of carbon dioxide from the flue gas.

[0037] The top of the heating tank 3 is connected and fixed to the bottom of the drain pipe 22, and the bottom of the heating tank 3 is connected and fixed to the drain pipe 31. Valves are connected and fixed to both the bottom of the drain pipe 22 and the drain pipe 31. In order to extract carbon dioxide from the recovery solution, the valves at the bottom of the drain pipe 22 and the drain pipe 31 are closed, and the recovery solution is heated in the heating tank 3, and carbon dioxide overflows from the recovery solution.

[0038] The top of the pressurized reaction tank 4 is connected and fixed to the top of the heating tank 3 via a pipe, and the bottom of the pressurized reaction tank 4 is connected and fixed to a discharge pipe 42. An ammonia inlet pipe 41 is connected and fixed to the top of the pressurized reaction tank 4, and the end of the ammonia inlet pipe 41 is connected and fixed to an ammonia delivery pipe. Valves are connected and fixed to the discharge pipe 42 and the pipe between the pressurized reaction tank 4 and the heating tank 3. During use, carbon dioxide in the heating tank 3 is guided into the pressurized reaction tank 4 through the pipe. The valve on the pipe between the pressurized reaction tank 4 and the heating tank 3 is closed, and at the same time, ammonia is guided into the pressurized reaction tank 4 through the ammonia inlet pipe 41. Carbon dioxide and ammonia react in the pressurized reaction tank 4 under high pressure and high temperature conditions to form urea, which is easy to reuse and recover carbon dioxide later.

[0039] refer to Figure 4 and Figure 5As shown, the filter element 5 includes a filter box 51. Two symmetrical vertical end faces of the filter box 51 are horizontally connected and fixed with screw tubes 52. Two symmetrical vertical sliding frames 56 are vertically arranged inside the filter box 51, and filter screens 561 are vertically fixed on the inner walls of the two sliding frames 56. Sliding strips 53 are horizontally symmetrically fixed on both the upper and lower sides of the inner wall of the filter box 51, and the sliding strips 53 are slidably assembled with the sliding frames 56. A motor 55 is fixed through the center of the bottom surface of the filter box 51, and a cam 551 is horizontally fixed at the output end of the motor 55. A spring 562 is horizontally fixed on one vertical end face of the sliding frame 56, and the other end of the spring 562 is fixed to the inner wall of the filter box 51. A rotating seat 563 is horizontally fixed at the bottom of the other vertical end face of the sliding frame 56, and a top wheel 5 is vertically rotatably connected to the rotating seat 563. 64. During use, flue gas enters the filter box 51 and flows through two sliding frames 56. The flue gas passes through the filter screens 561 in the two sliding frames 56 to remove impurities and dust from the flue gas, completing the flue gas filtration process. To avoid excessive dust adhering to the filter screens 561, the start motor 55 drives the cam 551 to rotate. The rotating cam 551 presses against the top wheel 564 on the sliding frame 56, causing the sliding frame 56 to slide horizontally on the slide bar 53, compressing the spring 562 to deform. When the cam 551 moves away from the sliding frame 56, under the deformation force of the spring 562, it pushes the sliding frame 56 to slide horizontally back on the slide bar 53. In this way, the horizontal reciprocating sliding of the sliding frame 56 causes the filter screen 561 to generate inertial vibration, shaking off the dust adhering to the filter screen 561, ensuring the flue gas flow rate on the filter screen 561 and the filtration effect of the filter screen 561.

[0040] refer to Figure 3 and Figure 4 As shown, a screw housing 231 is horizontally connected and fixed at the end of the smoke inlet diversion pipe 23. The screw tube 52 on one side of the filter box 51 is connected and assembled with the flue, and the screw tube 52 on the other side of the filter box 51 is threadedly connected and assembled with the screw housing 231 on the smoke inlet diversion pipe 23. The smoke inlet diversion pipe 23 is connected and assembled with the screw tube 52 on the other side of the filter box 51 to filter the air entering the smoke inlet diversion pipe 23. At the same time, the screw tube 52 on one side of the filter box 51 is connected and assembled with the flue to facilitate the guidance of flue gas into the filter box 51 for filtration.

[0041] refer to Figure 4 As shown, a through groove is symmetrically opened on the bottom surface of the filter box 51, and a dust collection box 54 is inserted into the through groove of the filter box 51. The top of the dust collection box 54 is open, and a magnetic strip 541 is horizontally fixed on the outside of the dust collection box 54. The magnetic strip 541 is magnetically connected to the bottom surface of the filter box 51. When the dust collection box 54 is inserted into the through groove on the bottom surface of the filter box 51, the magnetic strip 541 fixed on the top surface of the dust collection box 54 is magnetically attracted to the bottom surface of the dust collection box 54. The dust collection box 54 is used to collect dust that falls from the filter screen 561.

[0042] The working principle of this utility model is as follows:

[0043] During use, the flue gas is dispersed and guided to multiple recovery tanks 2 through the flue gas inlet diversion pipe 23. The dispersed flue gas is used for carbon dioxide recovery. The recovery solution, such as amine solution, used to recover carbon dioxide from the flue gas is dispersed and guided to multiple recovery tanks 2 through the liquid inlet diversion pipe 21. The recovery solution flows from top to bottom in multiple recovery tanks 2. At the same time, the flue gas guided into the recovery tanks 2 moves from bottom to top, thus ensuring that the flue gas flowing in opposite directions and the solvent used to recover carbon dioxide in the recovery solution are in full contact. Then, the flue gas with recovered carbon dioxide is discharged into the flue from the flue gas exhaust diversion pipe 24 at the top of multiple recovery tanks 2. The recovered solution that falls down is collected and flows down from the liquid outlet diversion pipe 22 and enters the heating tank 3, thus completing the recovery of carbon dioxide from the flue gas.

[0044] Close the valves at the bottom of the drain pipe 22 and the drain pipe 31, and heat the recovery solution in the heating tank 3. Carbon dioxide overflows from the recovery solution and is guided into the pressurized reaction tank 4 through the pipeline. Close the valve on the pipeline between the pressurized reaction tank 4 and the heating tank 3, and at the same time, use the ammonia inlet pipe 41 to guide ammonia into the pressurized reaction tank 4. Carbon dioxide and ammonia react under high pressure and high temperature conditions in the pressurized reaction tank 4 to form urea, which is convenient for later reuse of the recovered carbon dioxide.

[0045] Meanwhile, to ensure that dust in the flue gas does not affect the recovery of carbon dioxide, the screw tube 52 on one side of the filter box 51 in filter element 5 is connected to the flue and assembled to facilitate the guidance of flue gas into the filter box 51 for filtration. The flue gas inlet diversion pipe 23 is connected to the screw tube 52 on the other side of the filter box 51. The flue gas enters the filter box 51 and flows through two sliding frames 56. The flue gas passes through the filter screen 561 in the two sliding frames 56 to remove impurities and dust from the flue gas, completing the filtration process. To avoid the filter screen 561... When a lot of dust adheres to the filter screen, the motor 55 starts and drives the cam 551 to rotate. The rotating cam 551 presses against the top wheel 564 on the slide frame 56, causing the slide frame 56 to slide horizontally on the slide bar 53. This causes the spring 562 to deform. When the cam 551 moves away from the slide frame 56, the deformation force of the spring 562 pushes the slide frame 56 to slide horizontally back on the slide bar 53. The horizontal reciprocating sliding of the slide frame 56 causes the filter screen 561 to vibrate inertially, shaking off the dust adhering to the filter screen 561 and causing it to fall into the dust collection box 54.

[0046] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
