When a component is considered to be "located" on another component, it can be directly located on the other component or may also have a component that is centrally located.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figures 1 to 2 This application provides a cooling structure 10 for cooling gas within an exhaust pipe 20. The cooling structure 10 includes the exhaust pipe 20 and a clamping assembly 100. The clamping assembly 100 surrounds the outer wall of the exhaust pipe 20 and has a heat dissipation cavity 110 within it. The clamping assembly 100 includes a water inlet 101 located at the bottom of the clamping assembly 100 and a water outlet 102 located at the top of the clamping assembly 100. The water inlet 101 and the water outlet 102 are respectively connected to the heat dissipation cavity 110. The water inlet 101 is configured to introduce a cooling medium into the heat dissipation cavity 110, and the water outlet 102 is configured to discharge the cooling medium from the heat dissipation cavity 110.

[0025] The cooling structure 10 provided in this application effectively cools the high-temperature gas in the exhaust pipe 20 through the use of the clamping kit 100 and the cooling medium, reducing its temperature to within the allowable range of the dust collector and ensuring that the temperature of the gas entering the dust collector is within a safe range. A low-inlet, high-outlet cooling medium flow pattern is adopted to ensure that the cooling medium can fully absorb the heat in the exhaust gas. The cooled gas reduces thermal damage to the filter cloth inside the dust collector, extends the service life of the filter cloth, and avoids the problems of filter cloth damage and increased replacement frequency caused by high temperatures. Through effective cooling, corrosion and damage to the dust collector caused by high temperatures are reduced, lowering the system's maintenance frequency and repair costs, and extending the service life of the dust collector.

[0026] Please see Figure 1In one embodiment of this application, the clamping assembly 100 includes a first wall 111 and a second wall 112 disposed opposite to each other. A heat dissipation cavity 110 is formed between the first wall 111 and the second wall 112. The first wall 111 surrounds the outer wall of the exhaust pipe 20, and a plurality of heat dissipation fin groups 300 are spaced apart along the length of the exhaust pipe 20. The clamping assembly 100 and the heat dissipation fin groups 300 form a highly efficient heat dissipation structure. The first wall 111, surrounding the outer wall of the exhaust pipe 20, can effectively wrap the exhaust pipe 20 and enhance heat conduction. The design of the heat dissipation fin groups 300 further expands the heat dissipation area and enhances the cooling effect through the flow around the fins, making the heat exchange between the cooling medium and the high-temperature gas more complete, thereby significantly improving the cooling efficiency. In addition, the spaced arrangement of the heat dissipation fin groups 300 allows the cooling medium to be evenly distributed, avoiding the problem of uneven heat distribution and ensuring the stability and consistency of the cooling effect. This design not only effectively reduces the temperature of the gas inside the exhaust pipe 20, but also reduces damage to the dust removal equipment caused by high-temperature gas, extending the service life of the dust removal equipment and providing ideal working conditions for subsequent dust removal. Optionally, the first wall 111 is welded to the outer wall of the exhaust pipe 20.

[0027] Please see Figure 2 In one embodiment of this application, each heat dissipation fin assembly 300 includes a plurality of heat dissipation fins 301. The heat dissipation fins 301 extend from the first wall 111 toward the second wall 112, and the plurality of heat dissipation fins 301 are spaced apart along the periphery of the exhaust pipe 20. Each heat dissipation fin assembly 300, composed of a plurality of heat dissipation fins 300 and spaced apart along the periphery of the exhaust pipe 20, can further enhance heat dissipation performance. The distribution of the plurality of heat dissipation fins 301 allows the cooling medium to fully cover the outer wall of the exhaust pipe 20, thereby achieving more efficient heat conduction. Furthermore, the spaced arrangement of the heat dissipation fins 301 along the periphery can avoid excessive local heat concentration, ensuring uniform heat dissipation. This design not only improves the overall heat dissipation efficiency of the cooling system but also reduces equipment damage caused by local overheating, providing a more stable and reliable guarantee for the cooling of high-temperature gas inside the exhaust pipe 20.

[0028] Please see Figure 1In one embodiment of this application, the interval between two adjacent heat dissipation fin groups 300 along the length of the exhaust pipe 20 is 10 cm to 20 cm. Setting the interval between the heat dissipation fins 301 to 10 cm to 20 cm optimizes the overall performance of the heat dissipation structure. A reasonable interval ensures smooth flow of the cooling medium between the heat dissipation fins 301 while avoiding a decrease in heat dissipation effect due to excessive spacing. This interval ensures the fluidity of the cooling medium as it flows through the heat dissipation fins 301, while also fully utilizing the heat dissipation capacity of the heat dissipation fins 301, thereby achieving efficient heat dissipation. Furthermore, this spacing arrangement can reduce the volume and weight of the heat dissipation structure.

[0029] Please see Figure 2 In one embodiment of this application, the end of the heat dissipation fin 301 away from the first wall 111 is spaced apart from the second wall 112.

[0030] Please see Figure 2 In one embodiment of this application, the distance H between the end of the heat dissipation fin 301 furthest from the first wall 111 and the second wall 112 is 20 mm to 30 mm. Setting the distance H between the end of the heat dissipation fin 301 furthest from the first wall 111 and the second wall 112 to 20 mm to 30 mm further optimizes the overall performance of the heat dissipation structure. This distance setting ensures a reasonable flow path for the cooling medium as it flows through the heat dissipation fin 301, avoiding stress concentration problems caused by thermal expansion.

[0031] In one embodiment of this application, the first wall 111 and the second wall 112 are made of stainless steel. Using stainless steel effectively improves the durability and corrosion resistance of the cooling structure 10. Stainless steel has excellent high-temperature resistance and corrosion resistance, enabling long-term stable operation in high-temperature and complex environments, avoiding the problem of reduced cooling effect due to material damage. Furthermore, stainless steel also has high mechanical strength, capable of withstanding significant thermal and mechanical stresses, ensuring the stability and reliability of the cooling structure 10 under high-temperature and high-pressure environments. Optionally, 404 stainless steel or 316 stainless steel can be used.

[0032] Please see Figure 1 In one embodiment of this application, adjacent heat dissipation fins 301 are parallel to each other along the length of the exhaust pipe 20. By arranging adjacent heat dissipation fins 301 in parallel, the flow path of the cooling medium can be optimized, ensuring uniform heat dissipation. With this design, the cooling medium can better contact each heat dissipation fin 301 when flowing through it, thereby improving the overall heat dissipation efficiency of the dust removal equipment.

[0033] In one embodiment of this application, the cooling medium includes any one of water, heat transfer oil, and liquid nitrogen. Water, as a cooling medium, has a high specific heat capacity and good flow properties, making it suitable for most industrial cooling scenarios; heat transfer oil has a higher temperature tolerance, making it suitable for cooling needs in high-temperature environments; liquid nitrogen, as a cooling medium, can achieve rapid cooling, making it suitable for scenarios requiring high cooling speeds. The selection of multiple cooling media can be flexibly adjusted according to actual needs, ensuring the stability and reliability of the cooling effect.

[0034] Please see Figure 3 This application also provides a dust removal system, including a dust collection chamber 40 and the aforementioned cooling structure 10. The cooling structure 10 further includes an exhaust pipe 20 connected to the dust collection chamber 40. This dust removal system effectively solves the problem of damage to the dust collector caused by high-temperature exhaust gas. The cooling structure 10 effectively reduces the gas temperature to meet the operating requirements of the dust collector, ensuring its normal operation and long service life. Furthermore, the cooling structure 10 reduces damage to the exhaust pipe 20 and the dust collection chamber 40 from high-temperature gas, lowering the system's maintenance frequency and cost.

[0035] Please see Figure 3 In one embodiment of this application, the dust removal system further includes a cyclone device 50 connected to the air inlet end of the exhaust duct 20. The cyclone device 50 is configured to pre-treat the dust to reduce its concentration and temperature. By utilizing the rotational motion of the gas, the cyclone device 50 separates larger dust particles through centrifugal force, thereby reducing the impact of dust on the subsequent cooling structure 10 and the dust collector. Furthermore, the cyclone device 50 can also reduce the temperature of the gas, decreasing the burden on the cooling structure 10 and improving cooling efficiency. This design not only enhances the overall system's processing capacity but also extends the service life of the dust collector and cooling structure 10, reducing system maintenance costs and energy consumption, providing a more efficient and environmentally friendly solution for industrial production.

Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and substance of the technical solutions of this application.
