Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a high-temperature waste gas cooling treatment device. Background Art

[0002] High-temperature exhaust gases are directly released into the air, posing significant risks. First, high temperatures can rapidly increase the surrounding air temperature, exacerbating the urban heat island effect, impacting people's living comfort and increasing energy consumption for cooling. Second, high-temperature exhaust gases can cause localized temperature anomalies, affecting the habitats of plants and animals within ecosystems and damaging biodiversity. Furthermore, if high-temperature exhaust gases come into contact with flammable materials, they can pose a fire hazard. Furthermore, high temperatures can accelerate the reactions of some chemicals, producing new pollutants and further exacerbating environmental damage.

[0003] Currently, pipe heat exchangers are often used to treat high-temperature exhaust gas, recovering heat while simultaneously cooling it—killing two birds with one stone. However, over time, the outer surfaces of the heat exchange tubes, exposed to high-temperature exhaust gas for extended periods, are prone to forming a thick layer of dust. Over time, this dust layer severely impairs heat transfer, rendering this treatment method ineffective. Furthermore, cleaning each individual pipe is laborious and can damage the coating on the tubes, impacting their lifespan and performance. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a high-temperature exhaust gas cooling treatment device which prevents dust accumulation in the device, cleans multiple heat exchange tubes simultaneously, cleans safely and efficiently, and prevents the heat exchange tubes from being scratched.

[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is: a high-temperature exhaust gas cooling treatment device, including a cooling tank, wherein the two ends of the cooling tank are respectively integrally formed with a liquid inlet pipe and a liquid outlet pipe, and an air inlet pipe and an exhaust pipe are respectively provided near the two ends below the cooling tank, and fixed circular plates are respectively fixed on the side of the cooling tank away from each other where the air inlet pipe and the exhaust pipe are located, and a number of heat exchange tubes are fixed between the fixed circular plates, and a movable cleaning rack is provided in the cooling tank, and the cleaning rack is driven by a screw reciprocator fixed between the two fixed circular plates, and a cleaning ring 1 for cleaning the inner wall of the cooling tank and a cleaning ring 2 for cleaning the outer wall of each heat exchange tube are provided on the cleaning rack, and brushes are provided on the outer side of the cleaning ring 1 and the inner side of the cleaning ring 2, and a dust removal port is provided below the cooling tank.

[0006] Furthermore, the inner wall of the cooling tank is coated with a thermal insulation layer.

[0007] Based on the above characteristics, the insulation layer can reduce the heat exchange between the inside of the cooling tank and the outside world, making the cooling process more efficient, reducing energy consumption, and reducing the impact on the environment.

[0008] Furthermore, both ends of the cooling tank are bucket-shaped, and the ends of the liquid inlet pipe, liquid outlet pipe, air inlet pipe and exhaust pipe are all provided with pipe connecting seats.

[0009] Based on these features, the bucket-shaped design at both ends of the cooling tank facilitates coolant flow, reduces flow resistance, and allows coolant to quickly enter the heat exchange tubes, thereby improving cooling efficiency. The provision of pipe connectors makes it easier and more secure to connect the liquid inlet, outlet, air intake, and exhaust pipes to external pipes, ensuring the sealing and stability of the device.

[0010] Furthermore, the diameter of the fixed circular plate is the same as the inner diameter of the cooling tank, and the edge of the fixed circular plate is tightly connected to the inner wall of the cooling tank.

[0011] Based on the above characteristics, the fixed circular plate is tightly connected to the inner wall of the cooling tank, which can not only provide stable support for the heat exchange tube, but also effectively prevent exhaust gas and coolant from leaking from the connection between the fixed circular plate and the tank wall, thereby improving the sealing and safety of the device.

[0012] Furthermore, the heat exchange tubes are in the shape of multiple rings and are evenly spaced.

[0013] Based on the above characteristics, the multi-ring annular heat exchange tube arrangement greatly increases the contact area with the exhaust gas and improves the cooling efficiency. The evenly spaced arrangement ensures the uniformity of the cooling process, allowing the exhaust gas to fully contact the heat exchange tube and achieve better cooling effect.

[0014] Furthermore, a fixed plate is provided in the center of the cleaning rack, and the fixed plate is driven by a screw reciprocator. The cleaning ring 2 for cleaning the outer wall of the inner heat exchange tube is provided on the fixed plate, and the cleaning ring 2 for cleaning the outer wall of the outer heat exchange tube is connected to the fixed plate and the cleaning ring 1 through a connecting rod.

[0015] Based on these features, the fixed plate is driven by a screw reciprocator, ensuring stable movement of the cleaning frame and making cleaning more reliable. The connection rod not only stably connects and fixes cleaning rings one and two, but also increases the air flow space, which is conducive to improving exhaust gas cooling efficiency.

[0016] Furthermore, a sealing baffle is detachably provided at the dust removal port via screws.

[0017] Based on the above features, the detachable sealing baffle can not only ensure the sealing of the cooling tank, prevent exhaust gas leakage and dust entry, but also facilitate the cleaning of dust in the cooling tank.

[0018] Compared with the prior art, the advantages of the present invention are as follows: a cleaning ring 1 and a cleaning ring 2 are provided on the cleaning frame, and the cleaning frame is driven by a screw reciprocator provided in the cooling tank, so that the interior of the device can be cleaned at any time, and dust can be prevented from accumulating on the inner wall of the cooling tank and the outer wall of the heat exchange tube for a long time. This can ensure efficient heat exchange between the exhaust gas and the inside of the heat exchange tube to achieve cooling, and can also prevent dust from being tightly attached to the device and making it difficult to clean, thereby achieving a good cleaning effect. The cleaning ring 1 and multiple cleaning rings 2 provided on the cleaning frame can move synchronously, so as to simultaneously clean the inner wall of the cooling tank and multiple heat exchange tubes, which is beneficial to improving the cleaning efficiency. Brushes are provided on the outside of the cleaning ring 1 and the inside of the cleaning ring 2 to clean the inner wall of the cooling tank and the outer wall of the heat exchange tube, which can avoid scratching the inner wall of the cooling tank and the outer wall of the heat exchange tube, and the cleaning frame moves stably with the screw reciprocator, which can ensure that the brushes apply uniform force to the inner wall of the cooling tank and the outer wall of the heat exchange tube, further avoiding damage to the device.

The two ends of the cooling tank 1 are bucket-shaped. The bucket-shaped design at both ends of the cooling tank 1 is conducive to the flow of coolant, reduces flow resistance, and allows the coolant to quickly enter the heat exchange tube 7, which is conducive to improving cooling efficiency. The ends of the liquid inlet pipe 2, the liquid outlet pipe 3, the air intake pipe 4 and the exhaust pipe 5 are all provided with a pipe connection seat 10. The setting of the pipe connection seat 10 makes the connection between the liquid inlet pipe 2, the liquid outlet pipe 3, the air intake pipe 4 and the exhaust pipe 5 and the external pipe more convenient and firm, ensuring the sealing and stability of the device.

[0028] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 4 , the two ends of the cooling tank 1 are respectively integrally provided with a liquid inlet pipe 2 and a liquid outlet pipe 3, and the lower part of the cooling tank 1 near the two ends is respectively provided with an air inlet pipe 4 and an exhaust pipe 5, and the inside of the cooling tank 1 is located on the side away from the air inlet pipe 4 and the exhaust pipe 5. A fixed circular plate 6 is fixed thereon, and the diameter of the fixed circular plate 6 is the same as the inner diameter of the cooling tank 1. The edge of the fixed circular plate 6 is tightly connected to the inner wall of the cooling tank 1. The fixed circular plate 6 is tightly connected to the inner wall of the cooling tank 1, which can provide stable support for the heat exchange tube 7, and can also effectively prevent exhaust gas and coolant from leaking from the connection between the fixed circular plate 6 and the tank wall, thereby improving the sealing and safety of the device.

[0029] Combined with attachment Figure 5 , Attachment Figure 6 A number of heat exchange tubes 7 are fixed between the fixed circular plates 6. The heat exchange tubes 7 are in a multi-ring shape and are evenly spaced. The multi-ring arrangement of the heat exchange tubes 7 greatly increases the contact area with the exhaust gas and improves the cooling efficiency. The evenly spaced arrangement ensures the uniformity of the cooling process, allowing the exhaust gas to fully contact the heat exchange tubes 7 to achieve a better cooling effect.

[0030] Combined with attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6A movable cleaning rack is provided in the cooling tank 1, and the cleaning rack is driven by a screw reciprocator 8 fixed between two fixed circular plates 6. The cleaning rack is provided with a cleaning ring 14 for cleaning the inner wall of the cooling tank 1 and a cleaning ring 2 15 for cleaning the outer wall of each heat exchange tube 7. Brushes are provided on the outside of the cleaning ring 14 and the inside of the cleaning ring 2 15. A fixed plate 11 is provided in the center of the cleaning rack, and the fixed plate 11 is driven by the screw reciprocator 8. The fixed plate 11 is driven by the screw reciprocator 8, which ensures the stable movement of the cleaning rack and makes the cleaning work more reliable. The cleaning ring 2 15 for cleaning the outer wall of the inner heat exchange tube 7 is provided on the fixed plate 11. The cleaning ring 2 15 for cleaning the outer wall of the outer heat exchange tube 7 is connected to the fixed plate 11 and the cleaning ring 1 14 by a connecting rod 12. The setting of the connecting rod 12 can not only stably connect and fix the cleaning ring 14 and the cleaning ring 2 15, but also increase the gas flow space, which is conducive to improving the exhaust gas cooling efficiency.

[0031] Combined with attachment Figure 1 , Attachment Figure 2 A dust removal port 9 is provided below the cooling tank 1. A sealing baffle 13 is detachably provided at the dust removal port 9 by screws. The detachable sealing baffle 13 can ensure the sealing of the cooling tank 1, prevent exhaust gas leakage and dust from entering, and facilitate cleaning of the dust in the cooling tank 1.

The temperature of the coolant in the heat exchange tube 7 increases and eventually enters the coolant recovery equipment for recovery. The screw reciprocator 8 is opened regularly to drive the fixed plate 11 to move, and the cleaning ring 14 and the cleaning ring 2 15 move accordingly. The brushes thereon contact the inner wall of the cooling tank 1 and the outer wall of the heat exchange tube 7 for cleaning, so as to avoid dust accumulation in the device and affect the heat exchange efficiency. The cleaned dust falls to the dust removal port 9. The sealing baffle 13 is opened regularly to clean the dust at the dust removal port 9.
