Description

Technical Field

[0001] This utility model relates to the field of industrial furnaces, specifically to an industrial furnace. Background Technology

[0002] In the design of industrial furnace bodies, many complex problems often arise when it comes to the design of the top structure. Some furnace tops have a large span or a large arch radius, which directly leads to a significant increase in the overall weight of the top. During the cycle of equipment start-up and shutdown, the furnace top material undergoes continuous thermal expansion and contraction due to drastic temperature changes, which creates strong compressive stress on the arch base.

[0003] In related technologies, the arch foot structure is poorly designed, resulting in poor heat dissipation and a short service life. Utility Model Content

[0004] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0005] In related technologies, the arched foot structure has poor thermal conductivity, failing to efficiently transfer heat during furnace operation. This leads to localized heat accumulation, exacerbating thermal stress on the structure. Furthermore, the arched foot structure is undersized, failing to meet actual load-bearing requirements, resulting in poor structural integrity and weak mechanical properties. The connection method to the furnace body also fails to achieve a stable and reliable connection, with insufficient resistance to deformation at the connection points, making them prone to loosening and cracking under external environmental conditions.

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, embodiments of this utility model propose an industrial furnace with a reasonable configuration, strong heat dissipation capacity, and long service life.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The furnace 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the industrial furnace 100 according to an embodiment of the present invention includes a furnace shell 1, arch legs 2, and heat dissipation components 3.

[0024] The furnace shell 1 is provided with a thickness direction (e.g.) Figure 1 The first opening (shown in the inward and outward directions) penetrates the furnace shell 1. Specifically, as shown... Figure 1 As shown, the furnace shell 1 serves as the basic structure of the industrial furnace 100. The furnace shell 1 has a first opening that runs through the furnace shell 1 in the inward and outward directions, providing a heat conduction channel for heat exchange between the inside and outside of the furnace and for the connection of components.

[0025] The arch foot 2 is located inside the furnace shell 1 and extends circumferentially along the furnace shell 1. Specifically, as shown... Figure 1 As shown, the arch foot 2 is ring-shaped and located inside the furnace shell 1. The arch 4 is installed inside the furnace shell 1 through the arch foot 2, thereby providing an installation foundation for the arch 4.

[0026] The heat dissipation component 3 is disposed on the outer periphery of the furnace shell 1 and extends circumferentially along the furnace shell 1. The heat dissipation component 3 is connected to the arch foot 2 through the first opening so that the heat on the arch foot 2 can be dissipated through the heat dissipation component 3. Specifically, as shown in the figure... Figure 1As shown, the heat sink 3 can be annular and sleeved on the outer periphery of the furnace shell 1. The heat sink 3 is connected to the arch foot 2 through the first opening, allowing the heat accumulated on the arch foot 2 to be quickly conducted to the heat sink 3. During the operation of the industrial furnace 100, the area of ​​the arch foot 2 is exposed to a high-temperature airflow environment for a long time, and is subjected to continuous scouring and erosion by the high-temperature flue gas, resulting in excessively high temperatures. The heat sink 3 effectively dissipates the heat on the arch foot 2, reducing the temperature of the arch foot 2, preventing heat accumulation on the arch foot 2, reducing the thermal stress on the arch foot 2, alleviating the material performance degradation caused by high temperatures, extending the service life of the arch foot 2, and thus improving the stability and reliability of the entire furnace structure.

[0027] The industrial furnace 100 of this embodiment is equipped with a heat dissipation component 3, which is connected to the arch leg 2 to dissipate the heat accumulated on the arch leg 2, thereby reducing the temperature of the arch leg 2 and effectively preventing material performance degradation caused by excessive temperature. Furthermore, this effective temperature control of the arch leg 2 extends its service life and reduces the number of shutdowns for maintenance due to arch leg 2 damage, thus significantly improving the stability and reliability of the entire furnace structure and ensuring the long-term stable and efficient operation of the industrial furnace 100.

[0028] In some embodiments, the heat sink 3 includes a mounting shell 31 and a first castable refractory 32. The mounting shell 31 is disposed on the outer peripheral surface of the furnace shell 1 and is spaced apart from the first opening in the inward and outward directions. The mounting shell 31 extends circumferentially along the furnace shell 1 and has a mounting cavity. The first castable refractory 32 fills the mounting cavity and is connected to the arch foot 2 through the first opening. Specifically, as shown... Figure 1 As shown, the mounting shell 31 is an annular shell and is disposed on the outer circumferential surface of the furnace shell 1. The outer circumferential surface of the mounting shell 31 is spaced apart from the first opening. The first castable material 32 fills the mounting cavity of the mounting shell 31 and passes through the first opening to connect with the arch foot 2, forming a heat transfer channel. During the operation of the industrial furnace 100, the area of ​​the arch foot 2 experiences high temperature due to long-term exposure to high temperature and thermal stress. The arch foot 2 can quickly absorb the heat on its surface and conduct it to the surface of the mounting shell 31. The mounting shell 31 is made of a metal material with good thermal conductivity, which further accelerates heat dissipation. The heat is transferred to the external environment of the furnace through convection heat exchange between the surface of the mounting shell 31 and the surrounding air, thereby effectively reducing the temperature of the arch foot 2, alleviating the material performance degradation caused by high temperature, extending the service life of the arch foot 2, and ensuring the long-term stable operation of the industrial furnace 100.

[0029] In some embodiments, the upper end face of the mounting shell 31 is provided with a second opening extending through the mounting shell 31 in a vertical direction. The second opening is used to facilitate the loss of moisture from the first castable material 32 inside the mounting shell 31 during the furnace drying process. Specifically, as shown... Figure 1As shown, the upper surface of the mounting shell 31 has multiple second openings, evenly distributed across its surface. The first castable 32 contains a certain proportion of moisture during its preparation. If this moisture is not promptly and fully dissipated during the furnace drying process, it will severely impact the performance of the first castable 32. Residual moisture will rapidly vaporize at high temperatures, generating significant steam pressure, leading to defects such as pores and cracks inside the first castable 32. This reduces the strength and durability of the first castable 32, shortening its service life. Therefore, the second openings provide an effective channel for the dissipation of moisture from the first castable 32. During the furnace drying process, as the temperature rises, the moisture in the first castable 32 gradually vaporizes into water vapor. Due to internal pressure, the water vapor diffuses upwards. The second openings on the upper surface of the mounting shell 31 provide a path for the water vapor to escape. The water vapor quickly exits the mounting shell 31 through the second openings, thus preventing accumulation inside the first castable 32.

[0030] In some embodiments, the industrial furnace 100 further includes a first reinforcing member 33, which is disposed on the outer peripheral surface of the mounting shell 31 and extends circumferentially along the mounting shell 31. The first reinforcing member 33 is used to reinforce the mounting shell 31. Specifically, as Figure 1 As shown, the first reinforcing member 33 is a channel steel ring and is annular. It is fitted onto the outer circumference of the mounting shell 31 and connected to it. Thus, the annular first reinforcing member 33 can evenly distribute the reinforcing force, effectively reinforcing the mounting shell 31 in all directions and preventing structural deformation or damage caused by uneven local stress. For example, during the frequent start-up and shutdown of the industrial furnace 100, the mounting shell 31 undergoes repeated thermal expansion and contraction. The annular first reinforcing member 33 can limit excessive expansion and contraction of the mounting shell 31, maintaining its shape and dimensional stability. The annular first reinforcing member 33 also facilitates installation and fixation, achieving a tight fit with the mounting shell 31 and ensuring the reliability of the reinforcement effect.

[0031] During the operation of the industrial furnace 100, the mounting shell 31 may be affected by various factors, leading to a decrease in structural strength. For example, prolonged exposure to high temperatures can cause aging of the mounting shell 31 material, gradually reducing its mechanical properties; frequent thermal cycling can cause thermal stress fatigue inside the mounting shell 31, leading to the generation and propagation of microcracks. The presence of the first reinforcement member 33 can effectively suppress the impact of these adverse factors on the mounting shell 31. Through its high strength and rigidity, the first reinforcement member 33 shares part of the load borne by the mounting shell 31, reducing stress concentration and lowering the risk of structural failure. Simultaneously, the first reinforcement member 33 can also limit the deformation of the mounting shell 31, maintaining its relative positional accuracy with surrounding components, and ensuring the overall structural stability of the entire heat sink 3 and the industrial furnace 100.

[0032] In some embodiments, the industrial furnace 100 further includes a second reinforcing member 34, which is disposed on the outer peripheral surface of the furnace shell 1 and extends circumferentially along the mounting shell 31. The second reinforcing member 34 is located at the lower end of the mounting shell 31 and connected to the mounting shell 31, and is used to reinforce the mounting shell 31. Specifically, as Figure 1 As shown, the second reinforcing member 34 is a channel steel ring and is annular. It is fitted onto and connected to the outer circumferential surface of the furnace shell 1. The second reinforcing member 34 is also mounted on and connected to the lower end of the mounting shell 31. This allows the second reinforcing member 34 to not only connect to the furnace shell 1 but also to the lower end of the mounting shell 31, thus simultaneously reinforcing both the furnace shell 1 and the mounting shell 31. During the operation of the industrial furnace 100, when the mounting shell 31 is subjected to external forces, the second reinforcing member 34 can transfer some of the force to the furnace shell 1 through its connection, thus dispersing stress. Simultaneously, through its connection to the mounting shell 31, it directly supports and constrains the mounting shell 31, limiting its deformation. For example, during frequent start-ups and shutdowns of the industrial furnace 100, the mounting shell 31 undergoes repeated thermal expansion and contraction, generating significant thermal stress. The second reinforcing member 34 can buffer and absorb these thermal stresses to a certain extent, reducing stress fatigue of the mounting shell 31 and extending its service life.

[0033] In some embodiments, there are multiple first openings, which are spaced apart circumferentially along the furnace shell 1. The heat dissipation element 3 is connected to the arch foot 2 along with the multiple first openings. Thus, the multiple first openings spaced apart circumferentially can rationally guide heat dissipation and gas flow according to the distribution characteristics of the heat field and airflow, optimizing the thermal environment within the industrial furnace 100, improving thermal efficiency, and reducing energy consumption. For example, in some industrial furnaces 100 requiring uniform heating, by rationally setting the position and number of the first openings, the temperature inside the furnace can be made more uniform, avoiding local overheating or undercooling, thereby improving product quality and production efficiency. Furthermore, each first opening provides a channel for the heat dissipation element 3 to contact the heat source inside the furnace. The combined effect of multiple openings greatly increases the contact area between the heat dissipation element 3 and the heat inside the furnace, enabling faster heat dissipation.

[0034] In some embodiments, the arch foot 2 includes a first support plate 21, a second castable refractory 22, and an anchoring hook 23. The first support plate 21 is disposed inside the furnace shell 1 and extends circumferentially along the furnace body. The anchoring hook 23 is disposed inside the furnace shell 1 and located above the first support plate 21. The second castable refractory is disposed above the first support plate 21 and fills the outer periphery of the anchoring hook 23. Specifically, as shown... Figure 1As shown, the first support plate 21 is made of high-strength, high-temperature resistant alloy steel and is ring-shaped. The first support plate 21 is installed inside the furnace shell 1 by welding or bolting. The anchor hook 23 is also installed inside the furnace shell 1 and located above the first support plate 21. The anchor hook 23 is made of steel bars or special alloy materials, and its shape is usually "L" or "J" shaped, which can increase the contact area and friction between the anchor hook 23 and the second castable material 22, thereby improving the anchoring effect. One end of the anchor hook 23 is fixed to the furnace shell 1, and the other end extends into the second castable material 22. The second castable material 22 is poured above the first support plate 21 and on the outer periphery of the anchor hook 23. Thus, the first support plate 21, the anchor hook 23 and the second castable material 22 together form the arch foot 2 structure. The first support plate 21 provides a basic support platform for the entire arch foot 2, the anchor hook 23 enhances the connection strength between the second castable material and the first support plate 21 and the furnace shell 1, while the second castable material 22 fills the gaps and provides heat insulation protection. During the operation of the industrial furnace 100, the arch foot 2 structure is ensured to be stable and not deformed, thus improving the safety of the furnace body.

[0035] In some embodiments, the arch foot 2 further includes a straight furnace wall 24, which is disposed inside the furnace shell 1 and located below the first support plate 21. The straight furnace wall 24 includes a third castable refractory 241, a plurality of first high-alumina bricks 242, and a plurality of second high-alumina bricks 243. In a projection plane orthogonal to the inward and outward directions, the plurality of first high-alumina bricks 242 and the plurality of second high-alumina bricks 243 are alternately arranged in the vertical direction. In the projection plane orthogonal to the vertical direction, the first high-alumina bricks 242 are located inside the second high-alumina bricks 243, and the third castable refractory 241 fills the outer periphery of the straight furnace wall 24. Specifically, as shown in the figure... Figure 1 As shown, the straight furnace wall 24 is located inside the furnace shell 1 and below the first support plate 21. A second support plate 25 is also provided below the straight furnace wall 24. The second support plate 25 is annular and installed inside the furnace shell 1. The straight furnace wall 24 is made up of multiple first high alumina bricks 242 and multiple second high alumina bricks 243, which gives the straight furnace wall 24 the ability to hang materials. It is convenient to pour the third casting material 241 onto the inner circumference of the straight furnace wall 24. This not only enhances the overall integrity of the furnace structure, but also better adapts to the complex working environment inside the furnace, enhances the pressure resistance and load-bearing capacity of the arch foot 2, and improves the stability and reliability of the entire furnace structure.

[0036] In some embodiments, within a projection plane orthogonal to the inward and outward directions, a portion of the heat sink 3 is located within the second castable refractory 22, and another portion of the heat sink 3 is located within the straight furnace wall 24. Specifically, as... Figure 1 As shown, the heat sink 3 is wrapped around the outer periphery of the arch foot 2 by the furnace shell 1, which improves the heat dissipation efficiency of the heat sink 3.

[0037] In some embodiments, there are multiple anchor hooks 23, which are arranged in multiple rows at intervals along the vertical direction. Each row includes several anchor hooks 23 arranged at intervals along the circumference of the furnace shell 1. Thus, the second castable material 22 is firmly connected to the furnace shell 1 by multiple anchor hooks 23, preventing problems such as the second castable material 22 falling off, and ensuring the normal operation of the industrial furnace 100.

[0038] In some embodiments, the first casting material 32, the second casting material 22, and the third casting material 241 are all either refractory concrete or refractory plastic.

[0039] The industrial furnace 100 of this invention has the following advantages: In terms of heat dissipation, the mounting box effectively increases the heat dissipation area of ​​the arch leg 2, enabling efficient direct heat dissipation from the furnace and significantly reducing the temperature of the arch leg 2. This feature can effectively alleviate the degradation of material properties caused by high temperatures and extend the service life of the arch leg 2.

[0040] From the perspective of optimizing the furnace internal structure, the design of integrating the arch foot 2 with part of the lower furnace wall using castable materials (first castable 32, second castable 22, and third castable 241) greatly enhances the overall integrity of the furnace internal structure. This improved integrity allows the structure to better adapt to the complex working conditions inside the furnace, such as high temperature, high pressure, and material erosion. Simultaneously, the pressure resistance of the arch foot 2 is significantly enhanced, thereby effectively improving the stability and reliability of the entire furnace structure and reducing the risk of failures caused by structural instability.

[0041] Furthermore, the design detail of creating several small holes on the upper side of the mounting box is of great significance to the furnace drying process. These holes provide channels for moisture loss from the first castable refractory 32 during the drying process, which helps the first castable refractory 32 to solidify more quickly. Rapid and sufficient solidification ensures that the first castable refractory 32 reaches its design strength as early as possible, guaranteeing the safety and timeliness of the furnace body's subsequent commissioning.
