[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 2. This utility model discloses a high-temperature waste gas treatment device. While the circulating pump is working, the fan is controlled to rotate.

The spiral heat dissipation pipe not only extends the flow distance of the coolant but also reduces the space occupied by the heat dissipation pipe, thus improving the heat dissipation effect. In conjunction with the rotating fan, the multiple heat dissipation fins are cooled, and the heat in the multiple heat dissipation fins is blown into the air, which dissipates the coolant and further improves the heat dissipation effect. The cooled coolant flows through the heat dissipation pipe into the outlet pipe and is finally atomized and sprayed out through the first atomizing nozzle, thereby circulating and cooling the high-temperature waste gas.
[0018] 3.

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0029] The present invention provides the following preferred embodiments:
[0030] Example 1, as Figures 1-8 As shown, a high-temperature waste gas treatment device includes a base plate 1 and a cylinder 2 disposed above the base plate 1, and also includes an air inlet 33, a purification mechanism, a cooling mechanism and a neutralization mechanism. The cylinder 2 is disposed above the base plate 1, and the air inlet 33 is disposed on one side of the cylinder 2. Specifically, in actual use, a valve for controlling the opening and closing of the internal passage of the cylinder 33 should be installed on the cylinder 33.
[0031] The cooling mechanism includes a fan 3, a circulation component and a heat dissipation component. The heat dissipation component is located at the top of the cylinder 2, and the fan 3 is located between the cylinder 2 and the heat dissipation component.
[0032] The neutralization mechanism includes a stirring fan 4, a spraying component, and a stirring component. The stirring fan 4 is located inside the cylinder 2, and the spraying component is located on one side of the cylinder 2.
[0033] like Figures 1-8As shown, the circulation assembly includes a circulation pump 5, a collection plate 6, a connecting pipe 7, a heat dissipation pipe 8, a water inlet pipe 9, a water outlet pipe 10, and a first atomizing nozzle 11. The circulation pump 5 is fixedly mounted on the bottom plate 1 by a bracket. The collection plate 6 is fixedly mounted on the bottom surface of the cylinder 2. The two ends of the water inlet pipe 9 are fixedly connected to the bottom surface of the collection plate 6 and the water inlet end of the circulation pump 5, respectively. One end of the connecting pipe 7 is fixedly connected to the water outlet end of the circulation pump 5. The end of the connecting pipe 7 away from the circulation pump 5 is fixedly connected to one end of the heat dissipation pipe 8. The end of the heat dissipation pipe 8 away from the connecting pipe 7 is fixedly connected to one end of the water outlet pipe 10. The end of the water outlet pipe 10 away from the heat dissipation pipe 8 passes through the cylinder 2 and is fixedly connected to the first atomizing nozzle 11. The first atomizing nozzle 11 is located inside the cylinder 2. It should be noted that before cooling the high-temperature exhaust gas, the cylinder 2 contains coolant.
[0034] The high-temperature exhaust gas is connected to the external pipeline through the air inlet 33, allowing it to enter the lower part of the cylinder 2. Once inside, the circulation pump 5 operates under the control of the controller, driving the coolant inside the circulation assembly to circulate. When the circulation pump 5 operates, the coolant stored inside the cylinder 2 is introduced into the water inlet pipe 9 through the collection plate 6. The coolant in the water inlet pipe 9 is then fed into the connecting pipe 7 by the circulation pump 5 and transported to the heat dissipation pipe 8. The coolant is then transported to the water outlet pipe 10 through the heat dissipation pipe 8 and finally atomized and sprayed out through the first atomizing nozzle to cool the high-temperature exhaust gas inside the cylinder 2. Since the collection plate 6 has an arc-shaped structure, some of the coolant after cooling the exhaust gas adheres to the inner wall of the cylinder 2, while the rest drips directly into the inside of the collection plate 6. The coolant adhering to the inner wall of the cylinder 2 also falls into the collection plate 6 due to gravity, thus circulating the coolant.
[0035] like Figures 1-8 As shown, the heat dissipation assembly includes a fixing frame 13, an arc-shaped plate 14, multiple support frames 12, and multiple heat sinks 15. The multiple support frames 12 are all fixedly mounted above the cylindrical body 2. The arc-shaped plate 14 is fixedly mounted between the multiple support frames 12. The heat dissipation pipe 8 is fixedly mounted on the arc-shaped plate 14 via multiple heat sinks 15. The fixing frame 13 is fixedly mounted on the bottom surface of the arc-shaped plate 14. The fan 3 is rotatably mounted above the fixing frame 13.
[0036] After the coolant cools the high-temperature exhaust gas, its temperature will rise under the influence of the exhaust gas. The higher temperature of the coolant will affect the circulation and heat dissipation of the high-temperature exhaust gas. Simultaneously with the operation of the circulation pump 5, the fan 3 is controlled to rotate. When the high-temperature coolant is transported by the circulation pump 5 into the heat sink 8, multiple heat sinks 15 fixed to the outer wall of the heat sink 8 will conduct heat to the inside of the heat sink 8. Since the heat sink 8 is spiral-shaped, multiple connections can be made between the spiral heat sink 8 and the multiple heat sinks 15 when they come into contact. The heat dissipation pipe 8 conducts heat through DC, and the spiral heat dissipation pipe 8 not only extends the flow distance of the coolant but also reduces the space occupied by the heat dissipation pipe 8. The heat in the coolant inside the heat dissipation pipe 8 is transferred through multiple heat dissipation fins 15, and the rotating fan 3 dissipates heat from the multiple heat dissipation fins 15, blowing the heat in the multiple heat dissipation fins 15 into the air, that is, dissipating heat from the coolant. The cooled coolant flows through the heat dissipation pipe 8 into the water outlet pipe 10, and finally is atomized and sprayed out through the first atomizing nozzle, thereby circulating and cooling the high-temperature exhaust gas.
[0037] like Figures 1-8 As shown, the spraying assembly includes a placement frame 16, a water pump 17, an infusion pipe 18, an annular pipe 19, a storage tank 20, an annular frame 22, and multiple second atomizing nozzles 21. The annular frame 22 is fixedly mounted on the outer wall of the cylinder 2. The placement frame 16 is fixedly mounted above the base plate 1. The storage tank 20 is fixedly mounted on the top of the placement frame 16. The water pump 17 is located on one side of the storage tank 20. The input end of the water pump 17 is connected to the inner cavity of the storage tank 20 through a pipe. One end of the infusion pipe 18 is fixedly connected to the output end of the water pump 17. The end of the infusion pipe 18 away from the water pump 17 is fixedly connected to the annular pipe 19. The annular pipe 19 is fixedly mounted on the annular frame 22. One end of each second atomizing nozzle 21 is electrically connected to the annular pipe 19. The end of each second atomizing nozzle 21 away from the annular pipe 19 passes through the outer wall of the cylinder 2.
[0038] During the cooling process of high-temperature exhaust gas, the water pump 17 is controlled to draw in the alkaline solution inside the storage tank 20 and transport it to the annular pipe 19. The alkaline solution is then sprayed out through multiple second atomizing nozzles 21 via the annular pipe 19. This neutralizes the strong acid formed by the combination of hydrogen chloride, hydrogen fluoride, and other gases with the cooling water in the high-temperature and high-humidity environment, preventing corrosion and perforation of metal equipment such as strong acid pipes and fans.
[0039] like Figures 1-8As shown, the stirring assembly includes a motor 23, a drive shaft 24, a first bevel gear 25, a second bevel gear 26, and a support frame 27. The motor 23 is fixedly mounted on the outer wall surface of the cylinder 2. One end of the drive shaft 24 passes through the outer wall of the cylinder 2 and is fixedly connected to the output end of the motor 23. The first bevel gear 25 is fixedly mounted on the end of the drive shaft 24 away from the motor 23. The support frame 27 is fixedly mounted on the inner wall surface of the cylinder 2. The stirring fan 4 is rotatably mounted above the support frame 27. The second bevel gear 26 is fixedly mounted on the top of the stirring fan 4. The first bevel gear 25 and the second bevel gear 26 mesh with each other.
[0040] While multiple second atomizing nozzles 21 spray alkaline solution, motor 23 also works simultaneously, driving the first bevel gear 25 to rotate. Since the first bevel gear 25 and the second bevel gear 26 mesh with each other, the second bevel gear 26 also rotates, driving the stirring fan 4 to rotate, so that the alkaline solution sprayed by multiple second atomizing nozzles 21 can be fully mixed with the acidic liquid inside the cylinder 2.
[0041] like Figures 1-8 As shown, the purification mechanism includes a connecting pipe 28, a dry filter 29, an activated carbon filter box 30, and an exhaust pipe 31. The connecting pipe 28 is located on the outer wall of the cylinder 2. The dry filter 29 is located on the side of the connecting pipe 28 away from the cylinder 2. The activated carbon filter box 30 is located on the side of the dry filter 29 away from the cylinder 2. The exhaust pipe 31 is located on the top of the activated carbon filter box 30.
[0042] After the exhaust gas inside the cylinder 2 is cooled, it enters the dry filter 29 through the connecting pipe 28. The dry filter 29 filters out water vapor, oil and dust in the exhaust gas, thus purifying it. After being filtered by the dry filter 29, it continues to enter the activated carbon filter box 30 through the connecting pipe 28. The activated carbon filter box 30 adsorbs the organic components in the exhaust gas into the micropores of the activated carbon, further purifying the exhaust gas. The filtered gas is then discharged through the exhaust pipe 31.
[0043] The dry filter 29 consists of a shell, filter element, protective cover and exhaust port, etc., and the activated carbon filter box 30 consists of a box body, activated carbon layer, filtration system, etc. Both the dry filter 29 and the activated carbon filter box 30 are existing technologies and will not be described in detail here.
[0044] like Figures 1-8 As shown, an isolation plate 32 is provided between the cylinder 2 and the first atomizing nozzle 11. The isolation plate 32 prevents exhaust gas from entering between the top of the first atomizing nozzle 11 and the cylinder 2, thus avoiding dead zones.
