Description

Technical Field

[0001] The utility model relates to the technical field of gas processing, in particular to a flue gas processing device. Background Art

[0002] The large amount of flue gas generated by the factory needs to be treated and purified before it can be discharged. Among them, carbon capture is also a way of flue gas treatment. The carbon capture treatment mainly uses the absorbent solution to react with the flue gas in the reaction space of the absorption tower, thereby absorbing the carbon dioxide in the flue gas, which not only reduces the emission of greenhouse gases, but also can be used for subsequent utilization of carbon dioxide. In the reaction process between the absorbent solution and the flue gas, in order to improve the reaction efficiency, the absorbent solution is usually cooled and then transported to the reaction space to react with the flue gas. Generally, a liquid storage tank, a cooling pool and a solution pump are set at the bottom of the absorption tower. The solution pump is used to drive the absorbent solution in the liquid storage tank to flow through the cooling pool and be cooled, and then transported to the reaction space. Because the absorption tower is relatively high, the high-level solution pump needs to transport the absorbent solution to a relatively high position, resulting in a large lift required for the solution pump and high cost.

[0036] like Figures 1 to 3 As shown, in one embodiment, the flue gas treatment device includes a carbon capture module 100, a high-level liquid storage container 210, a low-level liquid storage container 220, a high-level solution pump 310, a low-level solution pump 320 and a cooling pool 400. The carbon capture module 100 is provided with a reaction space 101 for the reaction of the reaction solvent with the flue gas. The high-level liquid storage container 210 and the low-level liquid storage container 220 are both used to hold the reaction solvent. The cooling pool 400 is arranged at the bottom of the carbon capture module 100. The high-level solution pump 310 and the low-level solution pump 320 are both arranged at the bottom of the carbon capture module 100.

[0037] The high-level liquid storage container 210 is disposed at the side of the reaction space 101, and the high-level solution pump 310 is connected to the high-level liquid storage container 210 accordingly. There is a height difference between the high-level liquid storage container 210 and the high-level solution pump 310. The high-level solution pump 310 is used to drive the reaction solvent in the high-level liquid storage container 210 to flow through the cooling pool 400 to be cooled and then transported to the reaction space 101. The low-level liquid storage container 220 is disposed at the bottom of the carbon capture module 100, and the low-level solution pump 320 is used to drive the reaction solvent in the low-level liquid storage container 220 to flow through the cooling pool 400 to be cooled and then transported to the reaction space 101, and the position where the reaction solvent in the low-level liquid storage container 220 is transported to the reaction space 101 is lower than the position where the reaction solvent in the high-level liquid storage container 210 is transported to the reaction space 101.

[0038] Reference Figures 1 to 3 As shown, specifically, the carbon capture module 100 is square, and a reaction space 101 is formed inside. Flue gas enters the reaction space 101 from the bottom of the reaction space 101, flows upward along the reaction space 101, and reacts with the reaction solvent in the reaction space 101. The high-level liquid storage container 210 is arranged on the inner side wall of the reaction space 101, and is arranged approximately in the middle of the reaction space 101 in the longitudinal direction. The low-level liquid storage container 220 is arranged at the bottom of the reaction space 101.

[0039] Further, a cooling pool 400 is provided at the bottom side of the carbon capture module 100, and a coolant is provided in the cooling pool 400. A high-level solution pump 310 is provided beside the cooling pool 400, and the high-level solution pump 310 is connected to the high-level liquid storage container 210 to drive the reaction solvent in the high-level liquid storage container 210 to flow through the cooling pool 400 and be cooled. At the same time, the high-level solution pump 310 connected to the high-level liquid storage container 210 leads to the reaction space 101 via the first liquid infusion pipeline 311.

[0040] The low-level solution pump 320 is also disposed beside the cooling pool 400. The low-level solution pump 320 is connected to the low-level liquid storage container 220 to drive the reaction solvent in the low-level liquid storage container 220 to flow through the cooling pool 400 to be cooled. At the same time, the low-level solution pump 320 connected to the low-level liquid storage container 220 is led to the reaction space 101 via the second liquid infusion pipeline 321.

[0041] Continue to refer to Figures 1 to 3 As shown, the outlet position of the first infusion pipeline 311 in the reaction space 101 is higher than the outlet position of the second infusion pipeline 321 in the reaction space 101, that is, the first infusion pipeline 311 can deliver the reaction solvent to a higher position in the reaction space 101 than the second infusion pipeline 321. In other words, the reaction solvent in the high-position liquid storage container 210 is delivered to a higher position in the reaction space 101 than the reaction solvent in the low-position liquid storage container 220. In other words, the position where the reaction solvent in the low-position liquid storage container 220 is delivered to the reaction space 101 is lower than the position where the reaction solvent in the high-position liquid storage container 210 is delivered to the reaction space 101.

[0042] In the scheme of the present embodiment, a high-level liquid storage container 210 is arranged on the side of the reaction space 101, and a high-level solution pump 310 connected to the high-level liquid storage container 210 is arranged at the bottom of the carbon capture module 100, so that there is a height difference between the high-level liquid storage container 210 and the high-level solution pump 310, that is, there is a pressure difference between the high-level liquid storage container 210 and the corresponding high-level solution pump 310, so that the pressure difference between the high-level liquid storage container 210 and the corresponding high-level solution pump 310 can be used to supplement part of the power of the high-level solution pump 310 to supply liquid to a high place, thereby helping to reduce the head required for the solution pump to supply liquid to a high place, thereby reducing the cost of the solution pump to a certain extent.

[0043] Although setting the liquid storage container higher reduces the lift requirement of the solution pump, if all reaction solvents are stored and supplied in the high-position liquid storage container, the capacity of the high-position liquid storage container needs to be very large. At this time, installing a large-capacity liquid storage container at a higher position also increases the installation cost of the liquid storage container to a certain extent.

[0044] Therefore, further, by providing the low-level liquid storage container 220 and the low-level solution pump 320, the low-level solution pump 320 can drive the reaction solvent in the low-level liquid storage container 220 to flow through the cooling pool 400 and be cooled before being transported to the reaction space 101, and the position where the reaction solvent in the low-level liquid storage container 220 is transported to the reaction space 101 is lower than the position where the reaction solvent in the high-level liquid storage container 210 is transported to the reaction space 101. In other words, the high-level liquid storage container 210 and the low-level liquid storage container 220 are used to store and supply the total amount of reaction solvent required, so that the capacity of the high-level liquid storage container 210 can be relatively reduced, avoiding the high installation cost of the high-level liquid storage container 210.

[0045] Furthermore, because the position to which the reaction solvent in the low-level liquid storage container 220 is transported to the reaction space 101 is lower than the position to which the reaction solvent in the high-level liquid storage container 210 is transported to the reaction space 101, the lift required by the low-level solution pump 320 is also relatively low. This ensures that the total amount of reaction solvent required meets the requirements and effectively avoids the installation cost of the high-level liquid storage container 210 being too high while reducing the overall cost of the solution pump.

[0046] It should be noted that, in some other embodiments, the high-position liquid storage container and the low-position liquid storage container may also be arranged outside the reaction space.

[0047] It should be noted that, in some other embodiments, the flue gas treatment device may also include multiple high-level liquid storage containers and multiple high-level solution pumps, the number of high-level solution pumps is the same as the number of high-level liquid storage containers, and the multiple high-level liquid storage containers are arranged at intervals along the longitudinal direction of the reaction space, and the higher the position of the high-level liquid storage container, the higher the position of the reaction solvent transported to the reaction space by the corresponding high-level solution pump. The above arrangement can also play a role in reducing the overall cost of the solution pump and effectively avoiding the excessively high installation cost of the high-level liquid storage container.

[0048] Exemplarily, the flue gas treatment device is provided with two high-level liquid storage containers, one high-level liquid storage container is arranged at a position approximately one-half the height of the reaction space, and the reaction solvent is transported to a position approximately one-half the height in the reaction space by a corresponding high-level solution pump, and the other high-level liquid storage container is arranged at a position approximately three-quarters the height of the reaction space in the vertical direction, and the reaction solvent is transported to a position approximately three-quarters the height in the reaction space by a corresponding high-level solution pump.

[0049] like Figures 1 to 5As shown, the flue gas treatment device also includes two cooling components 500, and the cooling component 500 includes a cooling shell 510 and a cooling fan 520. The cooling shell 510 is arranged on a side wall of the carbon capture module 100, and defines a cooling channel 102 together with the wall of the carbon capture module 100. The cooling channel 102 has an air inlet and an air outlet. The cooling fan 520 is arranged in the cooling channel 102, and is used to promote the formation of a cooling airflow that enters the cooling channel 102 from the air inlet and is discharged from the air outlet to cool the reaction space 101 of the carbon capture module 100. The air inlet is formed at the bottom of the cooling shell 510, and the air outlet is formed at the top of the cooling shell 510, so that the cooling fan 520 is used to promote the formation of a cooling airflow that flows through the cooling channel 102 in the longitudinal direction.

[0050] Reference Figures 1 to 5 As shown, specifically, two cooling assemblies 500 are respectively disposed on two opposite side walls of the carbon capture module 100. The cooling housing 510 and the side wall of the carbon capture module 100 together form a square tube structure, thereby enclosing a cooling channel 102. Figure 4 As shown by the air flow direction arrow, when the cooling fan 520 is turned on, air is sucked in from the air inlet at the bottom of the cooling shell 510 , so that the air flows from bottom to top through the cooling channel 102 , and finally flows out of the cooling channel 102 from the air outlet at the top of the cooling shell 510 .

[0051] By arranging a cooling assembly 500 on the side wall of the carbon capture module 100, a cooling channel 102 is formed by the cooling shell 510 and the side wall surface of the carbon capture module 100, and the cooling fan 520 promotes the formation of a cooling airflow flowing through the cooling channel 102. In the process of the cooling airflow flowing through the cooling channel 102, the cooling airflow exchanges heat with the carbon capture module 100 via the side wall surface of the carbon capture module 100, thereby being able to cool the reaction space 101, which helps to improve the reaction efficiency of the reaction solvent and the flue gas in the reaction space 101.

[0052] By providing a cooling assembly 500 on opposite sides of the carbon capture module 100, it is helpful to improve the overall cooling efficiency of the reaction space 101. In addition, by forming the air inlet at the bottom of the cooling shell 510 and the air outlet at the top of the cooling shell 510, the cooling air flow flows through the cooling channel 102 in the longitudinal direction, that is, in the same direction as the air flow in the reaction space 101, so that the air flow discharged from the carbon capture module 100 and the air flow discharged from the cooling assembly 500 can be discharged together.

[0053] It should be noted that, in some other embodiments, the flue gas treatment device may also be provided with one, three or more cooling assemblies. In addition, when two cooling assemblies are provided, the two cooling assemblies may also be provided on two adjacent side walls of the carbon capture module. In addition, when multiple cooling assemblies are provided, the multiple cooling assemblies may also be provided side by side on one side wall of the carbon capture module.

[0054] In addition, it should be noted that, in some other embodiments, the cooling channel may also be configured so that the cooling airflow flows in the transverse direction.

[0055] like Figures 1 to 5 As shown, further, the flue gas treatment device includes an exhaust hood 600, which has an air inlet end and an exhaust end, and the air inlet end shrinks toward the exhaust end. The exhaust hood 600 is arranged on the top of the carbon capture module 100, and the air inlet end simultaneously covers the air outlet of the carbon capture module 100 and the air outlet of the cooling assembly 500, so that the gases flowing out of the carbon capture module 100 and the cooling assembly 500 are all discharged through the exhaust hood 600.

[0056] Reference Figures 1 to 5 As shown, specifically, the top ends of the two cooling assemblies 500 are flush with the top end of the carbon capture module 100, and the top ends of the two cooling assemblies 500 and the carbon capture module 100 together form a square outer edge, and the air inlet end of the exhaust hood 600 is square, correspondingly connected to the square outer edge formed by the top ends of the two cooling assemblies 500 and the carbon capture module 100. The exhaust hood 600 shrinks from the air inlet end to the exhaust end, so the gases exhausted from the carbon capture module 100 and the two cooling assemblies 500 can all be guided by the exhaust hood 600 and gathered to the exhaust end of the exhaust hood 600.

[0057] By utilizing the exhaust hood 600 to collect the gases exhausted from the carbon capture module 100 and the cooling assembly 500, it is convenient to uniformly discharge the gases exhausted from the carbon capture module 100 and the cooling assembly 500, and because the exhaust hood 600 contracts from the air intake end to the exhaust end, it helps to increase the airflow velocity, because the exhaust hood 600 collects multiple airflows, one of which will generate negative pressure after acceleration, and can also generate suction for the components that generate other airflows, which again plays a locking role, so that the multiple airflows interact with each other, which helps to improve the emission efficiency of the carbon capture module 100 and the cooling efficiency of the cooling assembly 500.

[0058] like Figure 1 to Figure 2As shown, in one embodiment, the flue gas treatment device includes a cooling water storage container 230 and a cooling pump 330. The cooling water storage container 230 is arranged near the top of the carbon capture module 100, and the cooling pump 330 is arranged at the bottom of the carbon capture module 100. The cooling pump 330 is connected to the cooling water storage container 230 to drive the cooling water in the cooling water storage container 230 to flow through the cooling pool 400 and be cooled and then transported to the reaction space 101.

[0059] Specifically, the cooling pump 330 is also arranged beside the cooling pool 400, and cooling water is used to spray from the top of the reaction space 101 into the reaction space 101 to cool the reaction space 101, thereby improving the reaction efficiency of the reaction solvent and the flue gas. The cooling water storage container 230 is arranged near the top of the carbon capture module 100, which is conducive to reducing the head required by the cooling pump 330.

[0060] Reference Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the carbon capture module 100 includes a first purification unit 110, a reaction unit 120, and a second purification unit 130. The first purification unit 110 is used to receive flue gas and pre-treat the flue gas. The reaction unit 120 is arranged above the first purification unit 110 and is connected to the first purification unit 110. The reaction unit 120 forms a reaction space so that the pre-treated flue gas enters the reaction space. The second purification unit 130 is arranged above the reaction unit 120 and is connected to the reaction unit 120, and is used to receive the flue gas from the reaction unit 120 that has reacted with the reaction solvent and absorb the dispersion medium in the flue gas. The flue gas treatment device also includes a recovery tank 700, which is used to recover the reaction solution after the first purification unit 110 reacts with the flue gas.

[0061] Specifically, the first purification unit 110 can desulfurize the flue gas, absorb the sulfur oxides in the flue gas using a reaction solution that can react with the sulfur oxides in the flue gas, and reduce the harmful substances in the flue gas finally discharged. Furthermore, the first purification unit 110 can also perform denitrification and dust removal on the flue gas. The reaction space of the reaction unit 120 receives the flue gas from the first purification unit 110, and the flue gas reacts with the reaction solvent in the reaction space, and the reaction solvent absorbs the carbon dioxide in the flue gas. Then, the treated flue gas enters the second purification unit 130 arranged above the reaction unit 120. The second purification unit 130 is used to absorb the dispersion medium in the flue gas, making the flue gas cleaner. Finally, the flue gas is discharged by the second purification unit 130.

[0062] Furthermore, the recovery tank 700 is used to recover the reaction solution after the reaction with the flue gas in the first purification unit 110, so as to recycle it after being treated.

[0063] The carbon capture module 100 includes the first purification unit 110, the reaction unit 120 and the second purification unit 130, so that the first purification unit 110, the reaction unit 120 and the second purification unit 130 are integrated into an integrated system, which reduces the occupied space, and is more convenient and quick to install and easy to transport.

[0064] Reference Figure 1 , Figure 5 and Figure 6 As shown, the recovery pool 700 and the cooling pool 400 are respectively arranged on opposite sides of the carbon capture module 100, so that the overall structure of the flue gas treatment device is more reasonable and occupies less space.

[0065] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
