Description

Technical Field

[0001] This utility model relates to the field of sulfur dioxide flue gas absorption towers, specifically a sulfur dioxide flue gas absorption tower with a trough separation absorption tower. Background Technology

[0002] Before being discharged, flue gas containing sulfides needs to be purified by a spray absorption tower to remove the sulfides.

[0003] In existing technologies, the spraying system inside the spray tower typically sprays out a sulfide absorbent (such as zinc acetate-sodium acetate solution) to react the sulfides and generate unsulfurized precipitates. However, in existing technologies, when the flue gas flows upward and reacts with the sprayed sulfide absorbent, some of the gas escapes to the top of the spray pipe before it has fully reacted, causing the sulfide-containing gas to be released into the atmosphere and causing air pollution. Utility Model Content

[0004] The purpose of this utility model is to provide a sulfur dioxide flue gas absorption tower with a trough separation absorption tower in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sulfur dioxide flue gas absorption tower with a trough separation absorption tower, including a spray absorption tower. The top of the spray absorption tower is equipped with an exhaust port, and the lower part of the outer wall of the spray absorption tower is integrally formed with an outwardly protruding air inlet. An outer fixing ring is fixedly installed on the upper part of the inner circumference of the spray absorption tower. An inner fixing pipe is fixedly installed on the inner circumference of the outer fixing ring through a connecting pipe. A rotating spraying mechanism that penetrates to the lower part of the inner fixing pipe is installed inside the inner fixing pipe, and a pipe mechanism that penetrates to the outside of the spray absorption tower is provided outside the inner fixing pipe.

[0006] As a further embodiment of this utility model: the pipeline mechanism includes a first inlet pipe and a second inlet pipe that penetrate from the outside of the spray absorption tower into the inner cavity of the spray absorption tower. The output end of the second inlet pipe is connected to the center of the top end of the inner fixed pipe. The inner cavity of the inner fixed pipe is connected to the inner cavity of the second inlet pipe. The outside of the spray absorption tower is provided with a first inlet pipe that penetrates into the inner cavity of the spray absorption tower and is connected to the outer periphery of the inner fixed pipe. The inner cavity of the inner fixed pipe is connected to the inner cavity of the first inlet pipe.

[0007] As a further embodiment of this utility model: a partition is fixedly installed at the center of the inner wall of the inner fixed tube, the inner cavity of the inner fixed tube is located above the partition as the upper cavity, the inner cavity of the inner fixed tube is located below the partition as the lower cavity, and an arc-shaped groove with an arc structure is opened inside the partition away from the first liquid inlet tube, and the upper cavity and the lower cavity are connected through the arc-shaped groove.

[0008] As a further embodiment of this utility model: the rotating spraying mechanism includes a vertical pipe rotatably connected to the center of the partition and the center of the lower cavity bottom plate. The vertical pipe extends through to the bottom of the inner fixed pipe. An impeller is coaxially fixedly connected to the top of the vertical pipe.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Please see Figures 1-4 In this embodiment of the present invention, a sulfur dioxide flue gas absorption tower includes a spray absorption tower 1. An exhaust port 3 is installed at the top of the spray absorption tower 1. An outwardly protruding air inlet 2 is integrally formed on the lower part of the outer wall of the spray absorption tower 1. An outer fixing ring 6 is fixedly installed on the upper part of the inner circumference of the spray absorption tower 1. An inner fixing pipe 8 is fixedly installed on the inner circumference of the outer fixing ring 6 through a connecting pipe 7. A rotating spraying mechanism that penetrates to the lower part of the inner fixing pipe 8 is installed inside the inner fixing pipe 8. A pipe mechanism that penetrates to the outside of the spray absorption tower 1 is provided outside the inner fixing pipe 8.

[0019] In this embodiment: the sulfide-containing waste gas enters the interior of the spray absorption tower 1 through the air inlet 2 under the delivery of the air pump. At the same time, the water pump connected to the pipeline mechanism is started simultaneously. The water pump inputs the sulfide absorbent into the pipeline mechanism and the rotary spray mechanism. At this time, the rotary spray mechanism rotates under the drive of the fluid. Then, both the pipeline mechanism and the rotary spray mechanism spray out the sulfide absorbent. At the same time, the rotary spray mechanism rotates to stir the sprayed sulfide absorbent and gas, so that they are more fully mixed. This avoids the problem that some sulfide gas is discharged from the exhaust port 3 before it is completely absorbed, thus improving the absorption efficiency.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The piping system includes a first inlet pipe 4 and a second inlet pipe 5 that pass through the outside of the spray absorption tower 1 and into the inner cavity of the spray absorption tower 1. The output end of the second inlet pipe 5 is connected to the center of the top of the inner fixed pipe 8. The inner cavity of the inner fixed pipe 8 is connected to the inner cavity of the second inlet pipe 5. The outside of the spray absorption tower 1 is provided with a first inlet pipe 4 that passes through the inner cavity of the spray absorption tower 1 and is connected to the outer periphery of the inner fixed pipe 8. The inner cavity of the inner fixed pipe 8 is connected to the inner cavity of the first inlet pipe 4. A partition 9 is fixedly installed at the center of the inner wall of the inner fixed pipe 8. The inner cavity of the inner fixed pipe 8 is located above the partition 9 and is called the upper cavity 10. The inner cavity of the inner fixed pipe 8 is located below the partition 9 and is called the lower cavity 11. The inner cavity of the partition 9 is located away from the first inlet pipe 4 and has an arc-shaped groove 13. The upper cavity 10 and the lower cavity 11 are connected through the arc-shaped groove 13.

[0021] In this embodiment: the water pump inputs the sulfide absorbent into the first inlet pipe 4 and the second inlet pipe 5. It enters the upper cavity 10 through the first inlet pipe 4. At this time, the sulfide absorbent entering the upper cavity 10 can drive the rotary spraying mechanism to rotate. After driving the rotary spraying mechanism to rotate, it enters the lower cavity 11 through the arc groove 13. Then, the sulfide hand sanitizer can enter the outer fixing ring 6 through the connecting pipe 7. Then, the sulfide absorbent entering the pipeline mechanism can be sprayed downward through the nozzles at the bottom of the outer fixing ring 6 and the inner fixing ring 8.

[0022] Please refer to this carefully. Figure 2 and Figure 3 The rotary spraying mechanism includes a vertical pipe 14 that is rotatably connected to the center of the partition 9 and the center of the bottom plate of the lower cavity 11. The vertical pipe 14 extends to the bottom of the inner fixed pipe 8. An impeller 12 is coaxially fixedly connected to the top of the vertical pipe 14. Sealing rings are installed at the top of the impeller 12, at the contact position between the top of the impeller 12 and the top of the inner wall of the inner fixed pipe 8, and at the top of the partition 9. Multiple sets of spray pipes 15 are installed on the outer wall of the vertical pipe 14.

[0023] In this embodiment: the sulfide hand sanitizer entering the upper cavity 10 through the No. 1 liquid inlet pipe 4 drives the impeller 12 to rotate, which in turn drives the vertical pipe 14 to rotate synchronously, and the vertical pipe 14 drives multiple sets of water spray pipes 15 to rotate.

[0024] Simultaneously, the sulfide absorbent entering through the No. 2 inlet pipe 5 enters the vertical pipe 14 and then enters the water spray pipe 15, finally being sprayed outward from the nozzle at the bottom of the outer periphery of the water spray pipe 15. This allows the water spray pipe 15 to rotate while spraying the sulfide absorbent, thereby stirring the sulfide absorbent and the sulfide waste gas, achieving full mixing of the waste gas and the sulfide absorbent, and preventing any unreacted sulfide gas from being discharged outward from the exhaust port 3.

[0025] Please refer to this carefully. Figure 2 and Figure 3 The impeller 12 has a circular hole at its center that is aligned with the inner cavity of the vertical pipe 14 and the output end of the second inlet pipe 5. The two ends of the connecting pipe 7 are connected to the outer fixing ring 6 and the inner cavity of the lower cavity 11, respectively. The output end of the first inlet pipe 4 is connected to the inner cavity of the partition 9. The output end of the first inlet pipe 4 is tangent to the rotation trajectory of the impeller 12.

[0026] In this embodiment: the sulfide absorbent entering the upper chamber 10 through the first inlet pipe 4 drives the impeller 12 to rotate, and the impeller 12 can drive the vertical pipe 14 and the spray pipe 15 to rotate. Then, it enters the lower chamber 11 through the arc groove 13 and enters the outer fixing ring 6 through the connecting pipe 7. After that, the sulfide absorbent can be sprayed out from the nozzle installed below the outer fixing ring 6 and the inner fixing ring 8.

[0027] The sulfide absorbent that enters the vertical pipe 14 from the No. 2 inlet pipe 5 enters the water spray pipe 15 and is then sprayed out from the nozzle of the water spray pipe 15.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
