Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to a capture device adapted to capture carbon dioxide in flue gas. Background Technology

[0002] Currently, the global carbon emission problem is becoming increasingly serious, and carbon dioxide capture technology in industrial flue gas has become a key means to mitigate global warming.

[0003] Regarding the aforementioned issues, existing carbon capture devices mostly employ a fixed spray tower structure, where flue gas reacts with the absorbent liquid through a packing layer. Some improved designs increase efficiency by adding more spray layers or by utilizing static distributors to expand the gas-liquid contact area.

[0004] Existing carbon capture devices have significant drawbacks: insufficient contact time between the solution and flue gas leads to increased escape gas, and static spraying modes struggle to cover the flue gas diffusion path. Gas-liquid mixing efficiency is limited by the fixed gas distribution structure, resulting in weak reaction area expansion capabilities. Furthermore, the synergistic mechanism of rotating spraying and forced circulation has not been effectively integrated in current technologies. Therefore, this paper proposes a capture device adapted for capturing carbon dioxide from flue gas to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3An embodiment of this utility model provides a capture device adapted to capture carbon dioxide in flue gas, comprising a housing 1, a solution tank 2 disposed inside the housing 1, a circulation component disposed on the side of the housing 1 for circulating the solution, the circulation component including a water pump 10, an output water pipe 9 connected to the output end of the water pump 10, an input water pipe 11 connected to the input end of the water pump 10, a spraying component installed inside the housing 1 for secondary capture of carbon dioxide in flue gas, an air intake component installed on the side of the housing 1 for the device to absorb flue gas, the spraying component including a motor 3, a rotating shaft 4 fixedly connected to the output end of the motor 3, a connecting ring 5 rotatably connected to the end of the rotating shaft 4 away from the motor 3, the top end of the connecting ring 5 fixedly connected to the end of the output water pipe 9 away from the water pump 10, a plurality of connecting shafts 6 disposed on the outside of the rotating shaft 4, a plurality of spray pipes 7 disposed on the outside of the connecting shafts 6, and a plurality of spray holes 8 opened on the outside of the spray pipes 7.

[0033] Specifically, during the capture of carbon dioxide from flue gas, the water pump 10 in the circulation assembly is turned on, and the input water pipe 11 on the water pump 10 draws solution from the solution tank 2. The drawn solution is input to the rotating shaft 4 of the spray assembly through the output water pipe 9 on the water pump 10. The solution flows through the rotating shaft 4 into the connecting shaft 6 and the spray pipe 7. The solution is sprayed out from the spray pipe 7. At the same time, the motor 3 of the spray assembly is turned on, and the output end of the motor 3 rotates the rotating shaft 4. The rotating shaft 4 drives the connecting shaft 6 and the spray pipe 7 to rotate, completing a large-range rotational spraying of the solution, and performing secondary carbon dioxide capture on the flue gas after it has reacted in the solution tank 2.

[0034] Reference Figures 1-5 The air intake assembly includes a fan 12, a housing 13 is fitted around the fan 12, an air pipe 14 is fixedly connected to the inside of the housing 13, multiple air outlets 15 are opened on the outside of the air pipe 14, a solution hopper 16 is installed on the outside of the housing 1, a solution pipe 17 is fixedly connected to the bottom of the solution hopper 16, the outside of the solution pipe 17 is fixedly connected to the inside of the housing 1, an air outlet 18 is fixedly connected to the top of the housing 1, a drain pipe 19 is installed inside the bottom of the housing 1, a valve 20 is fitted on the outside of the drain pipe 19, a base column 21 is fixedly connected to the bottom of the housing 1, a motor 3 is installed inside the base column 21, a base 22 is fixedly connected to the bottom of the base column 21, and multiple brake wheels 23 are installed at the bottom of the base 22.

[0035] Specifically, during flue gas carbon dioxide capture, fan 12 is turned on, drawing the flue gas into the gas pipe 14. The flue gas is then ejected into the solution tank 2 through the gas outlet 15 on the gas pipe 14. The gas outlet 15 increases the reaction area between the carbon dioxide in the flue gas and the solution. The installation of brake wheel 23 allows the device to stop in areas with high flue gas levels to complete carbon dioxide capture as needed. When adding solution, solution can be quickly added to the solution tank 2 through the solution hopper 16. When discharging used solution, the used solution can be quickly discharged by opening valve 20 on drain pipe 19, greatly increasing the practicality of the device.

[0036] Working Principle: During carbon dioxide capture of flue gas, the water pump 10 in the circulation assembly is turned on. The input water pipe 11 on the water pump 10 draws solution from the solution tank 2. The drawn solution is input to the rotating shaft 4 of the spray assembly through the output water pipe 9 on the water pump 10. The solution flows through the rotating shaft 4 into the connecting shaft 6 and the spray pipe 7. The solution is sprayed out from the spray pipe 7. At the same time, the motor 3 of the spray assembly is turned on. The output end of the motor 3 rotates the rotating shaft 4. The rotating shaft 4 drives the connecting shaft 6 and the spray pipe 7 to rotate, completing a large-range rotational spraying of the solution, thus performing secondary carbon dioxide capture on the flue gas after it has reacted in the solution tank 2. During the carbon dioxide capture of flue gas, the fan 12 is turned on. The fan 12 draws the flue gas into the gas pipe 14. The flue gas is sprayed out into the solution in the solution tank 2 through the gas outlet 15 on the gas pipe 14. The gas outlet 15 increases the reaction area between the carbon dioxide in the flue gas and the solution. The installation of brake wheel 23 allows the device to stop in areas with more flue gas as needed to capture carbon dioxide. When adding solution, the solution can be quickly fed into solution tank 2 through solution hopper 16. When discharging used solution, the used solution can be quickly discharged by opening valve 20 on drain pipe 19, greatly increasing the practicality of the device.
