[0008] Furthermore, the industrial furnace equipment also includes a negative pressure fan and a second pipeline, with the two ends of the second pipeline connected to the negative pressure fan and the tar collection device, respectively.

[0009] Furthermore, the connection point between the second pipe and the tar collection device is higher than the connection point between the first pipe and the tar collection device.

[0010] Furthermore, the first pipe and the second pipe are located on opposite sides of the tar collection device.

[0011] Furthermore, the minimum cross-sectional area of ​​the smoke collection chamber is greater than the maximum cross-sectional area of ​​the smoke inlet or outlet.

[0030] To address the energy waste and pollution problems associated with smoke emissions from existing industrial furnace equipment, this invention provides an industrial furnace device.

[0031] like Figures 1 to 7 As shown, the industrial furnace equipment includes a furnace body 10, a smoke collection device 30, and a tar collection device 40; the furnace body 10 is a cavity structure 11, and an annular flue 20 connected to the cavity structure 11 is opened at the top of the furnace body 10; the smoke collection device 30 includes a smoke inlet 31, a smoke collection chamber 32, and a smoke outlet 33 connected in sequence, the smoke inlet 31 is connected to the annular flue 20, and the smoke outlet 33 is connected to the tar collection device 40; the tar collection device 40 includes a collection chamber 41, the collection chamber 41 is connected to the smoke outlet 33, and the bottom wall of the collection chamber 41 is located below the smoke collection chamber 32.

[0032] Industrial furnace equipment is used to graphitize carbon-containing raw materials under high temperature conditions. During the graphitization process, a large amount of high-temperature fumes are generated, which contain tar and other pollutants.

[0033] To reduce energy waste and pollution, the furnace body 10 of the industrial furnace equipment of this application has a cavity structure 11. A large amount of smoke generated during graphitization of the raw materials in the cavity structure 11 passes sequentially through an annular flue 20, a smoke collection device 30, and a tar collection device 40 before being discharged. The annular flue 20 is located at the top of the furnace body 10 and is connected to the cavity structure 11, guiding the smoke along an annular path, thereby improving the uniformity and stability of smoke emission. The smoke inlet 31 of the smoke collection device 30 is connected to the annular flue 20, ensuring that the smoke can directly and quickly enter the smoke collection device 30 from the annular flue 20. The smoke undergoes initial enrichment within the smoke collection device 30, increasing the tar concentration of the smoke in the smoke collection chamber 32, and also allowing the smoke passing through the smoke collection chamber 32 to be preliminarily cooled before entering the tar collection device 40. The exhaust port 33 of the smoke collection device 30 is connected to the tar collection device 40, allowing the smoke to enter the collection chamber 41 of the tar collection device 40, achieving secondary cooling of the smoke. Specifically, the bottom wall of the collection chamber 41 is located below the smoke collection chamber 32. This arrangement utilizes the combined effects of gravity and smoke density stratification to further promote the separation of tar from the smoke, improving the efficiency of tar condensation and settling into the collection chamber 41. It also facilitates regular cleaning of the tar, ensuring the continuity and stability of the industrial furnace equipment operation.

[0034] This application optimizes the layout of the annular flue 20 and the tar collection device 40, effectively separating tar from the smoke, thereby reducing carbon emissions in the exhaust gas, reducing environmental pollution, making graphitization production more environmentally friendly, improving the operating efficiency and environmental performance of industrial furnace equipment, and making it suitable for large-scale industrial production with significant economic and social benefits.

[0035] Preferably, the minimum cross-sectional area of ​​the smoke collection chamber 32 is greater than the maximum cross-sectional area of ​​the smoke inlet 31 or the smoke outlet 33. For example... Figure 2 In the specific embodiment shown, the minimum cross-sectional area of ​​the smoke collection chamber 32 is greater than the maximum cross-sectional area of ​​the smoke inlet 31 or the smoke outlet 33. When smoke enters the larger smoke collection chamber 32 from the smaller cross-sectional smoke inlet 31, the smoke velocity decreases significantly. This increases the residence time of the smoke in the smoke collection chamber 32, which helps the tar and other particulate matter in the smoke to undergo initial settling and cooling. At this time, since the bottom wall of the collection chamber 41 is located below the smoke collection chamber 32, the smoke, after entering the relatively large collection chamber 41 from the relatively narrow smoke outlet 33, will further form density stratification. The upper layer of smoke has a higher temperature and lower density, while the lower layer of smoke is a layer of higher density tar components. This arrangement ensures that the smoke can be fully separated after entering the tar collection device 40 from the smoke collection device 30, avoiding the blockage problem caused by tar accumulation in the smoke collection device 30, and improving the operational stability and safety of the industrial furnace equipment.

[0036] Of course, in other embodiments not shown, the shape and size of the collection chamber 41 can be adjusted according to the actual furnace body 10 structure and smoke characteristics to achieve the best smoke treatment effect. This adjustability makes it possible to customize industrial furnace equipment, enabling it to adapt to different scales and types of production needs.

[0037] like Figure 3 , Figure 4 and Figure 5 In the specific embodiment shown, the furnace body 10 includes a furnace cover 12, a first annular plate 13, and a second annular plate 14; the first annular plate 13 is provided at the top opening of the cavity structure 11, the inner wall of the cavity structure 11 is fitted with the outer edge of the first annular plate 13, and a plurality of smoke outlets 131 are spaced apart along the circumference of the first annular plate 13; the furnace cover 12 is placed on the first annular plate 13, and the furnace cover 12 blocks at least a part of each smoke outlet 131; the second annular plate 14 is located on the outer periphery of the furnace cover 12 and is spaced apart from the first annular plate 13, and the furnace cover 12, the first annular plate 13, the second annular plate 14 and the cavity structure 11 together form an annular flue 20.

[0038] The furnace body 10 also includes a first annular plate 13, a furnace cover 12, and a second annular plate 14. The first annular plate 13 is located at the top opening of the cavity structure 11 and is tightly integrated with the inner wall of the cavity structure 11. Multiple smoke outlets 131 spaced circumferentially on the first annular plate 13 ensure porous smoke discharge. The first annular plate 13 is embedded in the cavity structure 11, so that the first annular plate 13 is spaced from the top edge of the cavity structure 11. The furnace cover 12 is directly placed on the first annular plate 13. At this time, each smoke outlet 131 is partially blocked by the furnace cover 12, and the smoke is discharged from the other part of each smoke outlet 131 that is not blocked by the furnace cover 12. The second annular plate 14 covers the top edge of the cavity structure 11 to the outer periphery of the furnace cover 12. The second annular plate 14 is spaced apart from the first annular plate 13. In other words, the outer periphery of the furnace cover 12, the first annular plate 13, the second annular plate 14, and the inner wall of the cavity structure 11 together form an annular flue 20. The inlet of the annular flue 20 is the portion of each smoke outlet 131 that is not obstructed by the furnace cover 12. The flue outlet 21 is located at the edge of the second annular plate 14. Smoke from the cavity structure 11 enters the interior of the annular flue 20 through each smoke outlet 131, flows around the interior of the annular flue 20, and is discharged from the flue outlet 21. The annular flue 20 not only enhances the sealing performance of the cavity structure 11 but also provides a buffer space for the smoke before discharge, making the smoke discharge more stable and reducing the risk of equipment damage caused by direct impact from high-temperature smoke. It also facilitates later maintenance and cleaning, ensuring the long-term stable operation of the industrial furnace equipment.

[0039] It should be noted that the first annular plate 13 and the second annular plate 14 are both annular plates adapted to the industrial furnace equipment of this application, and the center and the vicinity of the first annular plate 13 and the second annular plate 14 have openings.

[0040] like Figure 1 , Figure 2 , Figure 7 In the specific embodiment shown, the industrial furnace equipment also includes a negative pressure fan 53, which provides negative pressure during operation to promote the sequential flow of smoke through the cavity structure 11, the annular flue 20, the smoke collection device 30, and the tar collection device 40. It should be noted that the negative pressure provided by the negative pressure fan 53 is designed to prevent excessive stagnation of smoke in any structure of the industrial furnace equipment.

[0041] Of course, the negative pressure intensity can also be adjusted according to the actual needs of the application, without specific limitations here. At different production stages or according to specific production process requirements, the working parameters of the negative pressure fan 53, such as air volume and air speed, can be adjusted to ensure smooth smoke circulation, while adapting to various production conditions, thus enhancing the flexibility and applicability of the industrial furnace equipment.

[0042] Specifically, during the flow of smoke within the annular flue 20, the smoke can form a unidirectional annular flow path along the flue 20 under negative pressure. This not only improves the efficiency and capacity of the industrial furnace in treating smoke, but also ensures a more uniform and stable temperature and pressure distribution at the top of the furnace body 10. This helps avoid localized overheating or sudden pressure changes, reduces energy waste, extends the lifespan of the industrial furnace, and also reduces potential safety hazards. Furthermore, a stable pressure environment helps maintain the chemical reaction conditions within the furnace body 10, improving product quality and yield.

[0043] Optionally, the ratio of the area of ​​each flue gas outlet 131 covered by the furnace cover 12 to the uncovered free area can be set to 1:1 or adjusted to 1:2. The specific ratio should be determined based on the thermodynamic properties and smoke flow characteristics within the furnace body 10. This area ratio ensures effective smoke flow through the annular flue 20, preventing smoke stagnation and thus avoiding heat waste and safety hazards caused by the potential accumulation of high-temperature smoke in localized areas. It is worth noting that, to achieve optimal smoke flow and operational efficiency of the industrial furnace, the area ratio is not fixed but can be flexibly adjusted based on factors such as the size of the furnace body 10, the operating temperature range, and the expected smoke emission rate. Therefore, this application does not strictly limit the specific value of the area ratio but emphasizes an adjustable range adaptable to different operating conditions to meet the needs of various specific environments.

[0044] like Figure 1 and Figure 2In the specific embodiment shown, the industrial furnace equipment further includes a first pipe 50, with its two ends connected to a flue gas outlet 33 and a tar collection device 40, respectively. The first pipe 50 is set at a predetermined angle. The flue gas collection device 30 and the tar collection device 40 are connected through the first pipe 50, and the high-temperature smoke generated inside the furnace body 10 is guided to the first pipe 50 through the flue gas outlet 33.

[0045] The first pipe 50 is set at a predetermined angle. Optionally, the first pipe 50 is first laid along the rising direction of the smoke, and then turns at an angle of 45° to 90° or any angle in between towards the location of the tar collection device 40, guiding the smoke to change direction. At this time, the position of the connection between the first pipe 50 and the tar collection device 40 is higher than the position of the connection between the first pipe 50 and the smoke collection device 30. The smoke can enter the collection chamber 41 through the turning first pipe 50, realizing secondary cooling of the smoke and accelerating the separation of tar. The turning extension design of the first pipe 50 plays a role in obstructing the airflow of smoke, which can promote cooling and settling, and provide sufficient space and time to promote the condensation and precipitation of tar components. Finally, when the smoke reaches the tar collection device 40, most of the tar has been effectively separated through physical processes, which greatly reduces the processing load of the tar collection device 40, and also improves the efficiency and cleanliness of subsequent smoke purification treatment.

[0046] Preferably, such as Figure 2 As shown, the first pipe 50 turns at a 90° angle toward the location of the tar collection device 40.

[0047] In other embodiments not shown, the first pipe 50 can also be set at a preset angle of inclination. Optionally, the first pipe 50 can be set directly at an inclination, and the angle between the first pipe 50 and the direction of smoke rising can be 5° to 85° or any angle in between. In this case, the position of the connection between the first pipe 50 and the tar collection device 40 is still higher than the position of the connection between the first pipe 50 and the smoke collection device 30. The smoke can enter the collection chamber 41 through the gradually rising inclined first pipe 50, realizing the secondary cooling of the smoke and accelerating the separation of tar.

[0048] like Figure 1 and Figure 2 In the specific embodiment shown, the industrial furnace equipment also includes a second pipe 51, with its two ends connected to a negative pressure fan 53 and a tar collection device 40, respectively. The second pipe 51 is provided between the negative pressure fan 53 and the tar collection device 40. When the negative pressure fan 53 is working, it can provide negative pressure, allowing the smoke in the collection chamber 41 to enter the subsequent treatment system through the second pipe 51 and the negative pressure fan 53.

[0049] Specifically, the first pipe 50 and the second pipe 51 are located on opposite sides of the tar collection device 40, with the connection point of the second pipe 51 to the tar collection device 40 being higher than the connection point of the first pipe 50 to the tar collection device 40. That is, smoke enters the tar collection device 40 through the first pipe 50, where some condensed tar is separated, and then it exits the tar collection device 40 through the second pipe 51. Because the second pipe 51 is higher than the connection point of the first pipe 50 within the tar collection device 40, this arrangement promotes the separation and descent of tar from the smoke under gravity and stratification, while also allowing lighter gaseous components in the smoke to float to a higher area of ​​the collection chamber 41, making it easier for them to enter the second pipe 51 for further processing.

[0050] Under different production processes and operating conditions, the layout and angle of the first pipe 50 and the second pipe 51 can be flexibly adjusted according to actual needs. By precisely controlling the connection height difference between the first pipe 50 and the second pipe 51 relative to the tar collection device 40, the separation effect of tar and smoke can be further optimized, and the operational safety and efficiency of the industrial furnace equipment can be improved.

[0051] Considering the working environment of the first pipe 50 and the second pipe 51, the materials selected must be resistant to high temperature, corrosion and have good airtightness. At the same time, the connection method between the first pipe 50 and the second pipe 51 and the furnace body 10 and the tar collection device 40 ensures the sealing to avoid smoke leakage and ensure the stable operation and long-term reliability of the entire industrial furnace equipment.

[0052] In some optional embodiments, the furnace cover 12 includes a first cover body 121 and a second cover body 122, which are assembled together and are integrally cast. The furnace cover 12 is formed by assembling the first cover body 121 and the second cover body 122, both using integral casting technology and made of high-temperature resistant castable material to create a raised spherical shape. This design simplifies the manufacturing process of the furnace cover 12, improves its integrity and stability, better withstands pressure under high-temperature conditions, avoids cracks caused by loosening of the binder between refractory bricks, and enhances the heat insulation effect inside the furnace body 10.

[0053] In such Figure 6 In the specific embodiment shown, the first cover 121 and the second cover 122 have functional areas such as an electrode insertion port 124, a temperature measurement and observation port 125, and an explosion-proof port 126. The electrode insertion port 124 ensures the precise positioning of the electrode 56 or other heating elements, the temperature measurement and observation port 125 allows for non-contact temperature monitoring, and the explosion-proof port 126 has a safety mechanism for automatically sensing and releasing internal overpressure, greatly improving the safety factor of production. These openings meet the operational needs of the production process without affecting the sealing and safety of the furnace cover 12.

[0054] It should be noted that there is a small gap between the first cover 121 and the second cover 122. This gap does not affect the internal temperature of the cavity structure 11, while maintaining the internal pressure of the cavity structure 11 within a safe range.

[0055] In some embodiments not shown, the furnace cover 12 is assembled, and the inner ring edge of the first annular plate 13 is also provided with a rim groove, so that the furnace cover 12 can be accurately inserted into the rim groove of the inner ring edge of the first annular plate 13.

[0056] In some embodiments not shown, the industrial furnace equipment also includes a support beam with an opening at the top of the furnace body 10. The furnace cover 12 has mounting holes 123 through which fasteners are connected to the support beam. The furnace cover 12 has pre-drilled mounting holes 123, through which fasteners connect it to the support beam. This design not only ensures a stable connection between the furnace cover 12 and the furnace body 10 but also simplifies the installation and removal process of the furnace cover 12, making maintenance or replacement of the furnace cover 12 more convenient. The tight connection between the support beam and the furnace cover 12 improves the stability of the industrial furnace equipment and effectively prevents displacement of the furnace cover 12 under high-temperature operating conditions, ensuring production safety. During furnace body 10 maintenance or equipment adjustment, the control of the fastener tightness allows the furnace cover 12 to be easily separated from or re-secured from the support beam, which helps improve the maintenance efficiency of the industrial furnace equipment and reduce downtime, thereby improving the overall operating efficiency and economic benefits of the industrial furnace equipment.

[0057] In such Figure 7 In the specific embodiment shown, the industrial furnace equipment is driven by a rectifier transformer 55, and the electrode 56 provides heat to the raw materials or participates in the electrochemical reaction.

[0058] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0059] 1. The furnace body 10 of the industrial furnace equipment of this application has a cavity structure 11. The large amount of smoke generated by the graphitization of raw materials in the cavity structure 11 passes through the annular flue 20, the smoke collection device 30 and the tar collection device 40 in sequence before being discharged. The annular flue 20 is located at the top of the furnace body 10 and is connected to the cavity structure 11, guiding the smoke to flow along the annular path, thereby improving the uniformity and stability of smoke emission.

[0060] 2. The smoke inlet 31 of the smoke collection device 30 is connected to the annular flue 20, ensuring that the smoke can directly and quickly enter the smoke collection device 30 from the annular flue 20. The smoke undergoes initial enrichment within the smoke collection device 30. During this initial enrichment process, the tar concentration of the smoke in the smoke collection chamber 32 is increased, and the smoke passing through the smoke collection chamber 32 is also preliminarily cooled before entering the tar collection device 40. The smoke outlet 33 of the smoke collection device 30 is connected to the tar collection device 40, and the smoke enters the collection chamber 41 of the tar collection device 40, achieving secondary cooling of the smoke.

[0061] 3. The bottom wall of the collection chamber 41 is located below the smoke collection chamber 32. It can further promote the separation of tar from the smoke by utilizing the combined effect of gravity and smoke density stratification, improve the efficiency of tar condensation and settling into the collection chamber 41, and facilitate regular cleaning of tar, thus ensuring the continuity and stability of the industrial furnace equipment operation.

[0062] 4. By optimizing the layout of the annular flue 20 and the tar collection device 40, this application effectively separates the tar in the smoke, thereby reducing carbon emissions in the exhaust gas, reducing environmental pollution, making graphitization production more in line with environmental protection requirements, improving the operating efficiency and environmental performance of industrial furnace equipment, and making it suitable for large-scale industrial production with significant economic and social benefits.
