Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flue gas treatment devices, specifically an industrial flue gas carbon reduction and emission reduction treatment device. Background Technology
[0002] Until the middle of this century, fossil fuels such as coal will remain the world's primary and most reliable energy source. However, this will lead to environmental constraints and global warming caused by excessive CO2 emissions. To address these issues, the country has proposed a dual-carbon strategy of "carbon neutrality and carbon peaking" to encourage enterprises to reduce carbon emissions from industrial flue gas.
[0003] In current carbon reduction and emission reduction equipment, adsorption is the main method. Carbon-containing flue gas is introduced into an absorption tower, where it is sprayed with an adsorption solution for adsorption. The adsorbed solution is then introduced into a regeneration tower for separation and regeneration. However, there are some functional shortcomings in actual use, and there is room for improvement. For example, in the spraying process, packing material is usually used in conjunction with the solution to increase the gas-liquid contact surface. While the packing material reduces the flue gas velocity, it can also cool the flue gas and the solution. Currently, cooling mainly relies on the physical properties of the packing material itself. As the solution is continuously heated and regenerated, the cooling effect of the packing material also decreases, and it does not have the function of continuous cooling.
[0004] Now, a novel industrial flue gas carbon reduction and emission reduction treatment device is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an industrial flue gas carbon reduction and emission reduction treatment device to solve the problem mentioned in the background art of not having a continuous cooling function.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial flue gas carbon reduction and emission reduction treatment device, comprising a bottom support frame, an absorption tower fixedly connected to the left side of the top of the bottom support frame, a regeneration tower fixedly connected to the right side of the top of the bottom support frame, a liquid outlet at the bottom end of the absorption tower, an air inlet welded to the left side of the absorption tower, a first spray plate inside the absorption tower, an air outlet fixedly connected to the top of the absorption tower, a liquid inlet on the right side of the absorption tower, a return liquid inlet fixedly connected to the left side of the regeneration tower, a second spray plate inside the regeneration tower, a reflux port fixedly connected to the bottom end of the regeneration tower, a first circulation pump and a second circulation pump arranged between the absorption tower and the regeneration tower, a heater fixedly connected to the right side of the first circulation pump, a return liquid pipe fixedly connected between the heater and the return liquid inlet, an inlet pipe fixedly connected between the liquid inlet and the second circulation pump, and a cooling component for accelerated cooling inside the absorption tower.
[0007] The cooling assembly includes two sets of first stainless steel support plates, which are fixedly connected inside the absorption tower. Copper coils are inserted and fixed inside the first stainless steel support plates. A water inlet is welded to the left side of the copper coils, and a water outlet is welded to the right side of the copper coils. Multiple sets of first leakage holes are opened inside the first stainless steel support plates, and multiple sets of packing are laid on the top of the first stainless steel support plates.
[0008] As a further technical solution of this utility model, the inner diameters of the copper coil, the inlet, and the outlet are the same, and the interiors of the copper coil, the inlet, and the outlet are interconnected.
[0009] As a further technical solution of this utility model, the first leakage hole is in the shape of a trumpet with a smaller upper diameter and a larger lower diameter, and the inner diameter of the first leakage hole is smaller than the outer diameter of the packing.
[0010] As a further technical solution of this utility model, the first leakage hole extends through the upper and lower ends of the first stainless steel support plate, and the first leakage holes are arranged at equal intervals.
[0011] As a further technical solution of this utility model, a sensor mounting base is welded to the right side of the air outlet, and a carbon dioxide sensor is fixedly connected to the right side of the sensor mounting base. The air outlet and the interior of the sensor mounting base are connected, and the carbon dioxide sensor passes through the sensor mounting base and extends into the interior of the air outlet.
[0012] As a further technical solution of this utility model, the regeneration tower is internally fixedly connected to multiple sets of second stainless steel support plates, and the second stainless steel support plates are internally fixedly connected to electric heating coils. Multiple sets of second leakage holes are opened inside the second stainless steel support plates. The second leakage holes are funnel-shaped with a larger upper part and a smaller lower part. The second leakage holes pass through the upper and lower ends of the second stainless steel support plates, and the second stainless steel support plates are arranged at equal intervals.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the industrial flue gas carbon reduction and emission reduction treatment device not only realizes the function of continuous cooling, but also realizes the function of flue gas carbon content detection, and also realizes the function of secondary heating and reboiling.
[0014] (1) By setting up a first stainless steel support plate, copper coil, water inlet, water outlet, first leakage hole and packing, when in use, the flue gas after dust removal enters the absorption tower through the air inlet. The flue gas rises from bottom to top, and the first spray plate sprays the adsorption solution from top to bottom. The flue gas travels upward through the first leakage hole on the first stainless steel support plate and fully contacts the solution inside the packing. The water inlet and water outlet of the copper coil are connected to the chiller respectively. The chilled water is continuously pumped to maintain the low temperature. The entire first stainless steel support plate is in a low temperature state, which can keep the flue gas and solution in a low temperature state and realize the function of continuous cooling.
[0015] (2) By setting up a sensor mounting base and a carbon dioxide sensor, when in use, the carbon dioxide in the flue gas is captured and adsorbed by the solution, and the remaining flue gas is discharged from the outlet. The carbon dioxide sensor on the sensor mounting base keeps detecting the carbon content of the discharged flue gas, which is convenient for subsequent querying and understanding of the processing status, and realizes the function of detecting the carbon content of flue gas.
[0016] (3) By setting a second stainless steel support plate, an electric heating coil and a second drain hole, when in use, the solution that has adsorbed carbon dioxide is discharged through the outlet and pumped into the heater by the first circulation pump. After being heated by the heater, it enters the second spray plate along the return pipe and return port. It is sprayed downward through the second spray plate. Carbon dioxide is precipitated in the heated solution, the solution is reduced, and carbon dioxide is discharged and collected from the top outlet. The solution flows downward and multiple sets of second stainless steel support plates receive the solution. The electric heating coil heats the second stainless steel support plate to raise the temperature of the solution a second time, so that it boils again and further discharges the internal carbon dioxide. The second drain hole, which is larger at the top and smaller at the bottom, facilitates the solution to seep down and realizes the function of secondary heating and re-boiling.

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.
[0023] Example: Please refer to Figure 1-4 An industrial flue gas carbon reduction and emission reduction treatment device includes a bottom support frame 1, an absorption tower 2 fixedly connected to the top left side of the bottom support frame 1, a regeneration tower 26 fixedly connected to the top right side of the bottom support frame 1, a liquid outlet 27 at the bottom end of the absorption tower 2, an air inlet 3 welded to the left side of the absorption tower 2, a first spray plate 10 inside the absorption tower 2, an air outlet 11 fixedly connected to the top of the absorption tower 2, a liquid inlet 14 on the right side of the absorption tower 2, and a return valve fixedly connected to the left side of the regeneration tower 26. The absorption tower 26 is equipped with a second spray plate 20 inside the liquid inlet 19 and a return port 25 fixedly connected to the bottom end of the regeneration tower 26. A first circulation pump 16 and a second circulation pump 24 are arranged between the absorption tower 2 and the regeneration tower 26. A heater 17 is fixedly connected to the right side of the first circulation pump 16. A return pipe 18 is fixedly connected between the heater 17 and the return port 19. An inlet pipe 15 is fixedly connected between the liquid inlet 14 and the second circulation pump 24. The absorption tower 2 is equipped with a cooling component for accelerated cooling.
[0024] Please see Figure 1-4 An industrial flue gas carbon reduction and emission reduction treatment device also includes a cooling component. The cooling component includes two sets of first stainless steel support plates 4. The two sets of first stainless steel support plates 4 are fixedly connected inside the absorption tower 2. Copper coils 5 are inserted and fixed inside the first stainless steel support plates 4. A water inlet 6 is welded to the left side of the copper coils 5 and a water outlet 7 is welded to the right side of the copper coils 5. Multiple sets of first leakage holes 8 are opened inside the first stainless steel support plates 4. Multiple sets of packing 9 are laid on the top of the first stainless steel support plates 4.
[0025] The inner diameters of the copper coil 5, the inlet 6, and the outlet 7 are the same. The interiors of the copper coil 5, the inlet 6, and the outlet 7 are connected. The first drain hole 8 is a funnel shape with a smaller upper diameter and a larger lower diameter. The inner diameter of the first drain hole 8 is smaller than the outer diameter of the packing 9. The first drain hole 8 passes through the upper and lower ends of the first stainless steel support plate 4. The first drain holes 8 are arranged at equal intervals to facilitate cooling of the solution.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, the flue gas travels upward through the first leakage hole 8 on the first stainless steel support plate 4, and comes into full contact with the solution inside the packing 9. The inlet 6 and outlet 7 of the copper coil 5 are connected to the chiller, and the low temperature is maintained by continuously pumping cold water. The entire first stainless steel support plate 4 is in a low temperature state, which can keep the flue gas and solution passing through at a low temperature.
[0027] A sensor mounting base 12 is welded to the right side of the air outlet 11. A carbon dioxide sensor 13 is fixedly connected to the right side of the sensor mounting base 12. The interiors of the air outlet 11 and the sensor mounting base 12 are connected. The carbon dioxide sensor 13 passes through the sensor mounting base 12 and extends into the interior of the air outlet 11 to monitor the carbon content of the air after adsorption.
[0028] Specifically, such as Figure 1 and Figure 3 As shown, the carbon dioxide sensor 13 on the sensor mounting base 12 keeps the carbon content of the exhaust gas in order to facilitate subsequent querying and understanding of the processing status.
[0029] The regeneration tower 26 has multiple sets of second stainless steel support plates 21 fixedly connected inside. The second stainless steel support plates 21 have electric heating coils 22 fixedly connected inside. The second stainless steel support plates 21 have multiple sets of second leakage holes 23 inside. The second leakage holes 23 are funnel-shaped with a larger upper part and a smaller lower part. The second leakage holes 23 pass through the upper and lower ends of the second stainless steel support plates 21. The second stainless steel support plates 21 are arranged at equal intervals to facilitate secondary heating of the solution.
[0030] Specifically, such as Figure 1 and Figure 4 As shown, multiple sets of second stainless steel support plates 21 receive the solution, and electric heating coils 22 heat the second stainless steel support plates 21 to raise the temperature of the solution a second time, causing it to boil again and further expel the internal carbon dioxide. The second leakage hole 23, which is larger at the top and smaller at the bottom, facilitates the seepage of the solution.
[0031] Working Principle: In operation, the flue gas, after dust removal, enters the absorption tower 2 through the inlet 3. The flue gas rises from bottom to top, and the first spray plate 10 sprays the adsorption solution from top to bottom. The flue gas then travels upwards through the first drain hole 8 on the first stainless steel support plate 4, making full contact with the solution inside the packing 9. The inlet 6 and outlet 7 of the copper coil 5 are connected to a chiller, and continuous pumping of chilled water maintains a low temperature. The entire first stainless steel support plate 4 remains at a low temperature, ensuring that both the flue gas and the solution are kept at a low temperature. After the carbon dioxide in the flue gas is captured and adsorbed by the solution, the remaining flue gas is discharged from the outlet 11. The carbon dioxide sensor 13 on the sensor mounting base 12 continuously detects the carbon content of the discharged flue gas, facilitating subsequent monitoring of the treatment status. The solution that has adsorbed carbon dioxide is discharged through outlet 27 and pumped into heater 17 by first circulation pump 16. After being heated by heater 17, it enters the second spray plate 20 through return pipe 18 and return port 19. It is sprayed downward through second spray plate 20. Carbon dioxide is precipitated in the heated solution, the solution is reduced, and carbon dioxide is discharged and collected from the top outlet. The solution flows downward and multiple sets of second stainless steel support plates 21 receive the solution. Electric heating coil 22 heats the second stainless steel support plates 21, which reheats the solution and makes it boil again, further expelling the internal carbon dioxide. The second leakage hole 23, which is larger at the top and smaller at the bottom, facilitates the seepage of the solution.
