Description

Technical Field

[0001] This utility model relates to the field of activated coke regeneration, specifically to an activated coke regeneration furnace device with nitrogen protection. Background Technology

[0002] Activated coke is widely used in water purification and air pollution control. After adsorption saturation, it needs to be restored to its performance through thermal regeneration (carbonization and decomposition of organic matter at high temperature of 600-950℃). However, activated coke is prone to react with oxygen at high temperature, which leads to increased carbon loss and pore damage. Therefore, protection with an inert atmosphere is the key to improving the quality of regeneration.

[0003] Currently, rotary kilns are widely used in activated coke regeneration due to their uniform heating of materials. The closest existing technology is the authorized utility model patent "An Internally Heated Rotary Kiln for Activated Coke with Diverse Raw Materials" (Patent No.: CN220288141U, Authorization Announcement Date: January 2, 2024), which optimizes the raw material flow rate by adjusting the tilt angle of the rotary kiln and solves the material adhesion problem with buffer support, making it suitable for the regeneration of diverse raw materials.

[0004] However, this existing technology has significant drawbacks:

[0005] No inert gas protection mechanism: There is no inert gas system, and it relies solely on internal heating. The activated coke is easily oxidized at high temperatures, and the carbon loss rate reaches 15%-25%. In addition, air seeps in from the feed / discharge gap, which aggravates the loss.

[0006] Low transmission reliability: The existing technology (CN220288141U) adopts conventional motor-gear transmission without a backlash compensation mechanism. During long-term operation, the gear meshing clearance increases to 0.5-1.0mm, causing unstable converter rotation and exacerbating uneven conveying and heating. Summary of the Invention

[0007] This utility model aims to solve one of the technical problems existing in the prior art.

[0008] This application provides a nitrogen-protected activated coke regeneration furnace device, including a feeding assembly, a rotary kiln, and a nitrogen protection assembly. The feeding assembly is used to feed the activated coke to be regenerated into the rotary kiln, and the nitrogen protection assembly is used to circulate nitrogen into the rotary kiln. The rotary kiln generates high-temperature carbonization of the organic matter attached to the activated coke to be regenerated.

[0009] The feeding assembly includes a feeding hopper, a feeding pipe, an auger, and a drive motor. The bottom of the feeding hopper is connected to the feeding pipe, and the auger is installed in the feeding pipe and is driven by the drive motor to feed the activated coke to be regenerated in the feeding pipe into the rotary kiln.

[0010] The rotary kiln includes a furnace body, furnace tubes with spiral blades on the inner wall, a heating unit, and a rotary drive unit. The furnace tubes are rotatably installed in the furnace body via the rotary drive unit, and the heating unit is located in the furnace body for heating the furnace tubes.

[0011] The rotary drive unit includes a pair of rotary drums, a pair of rolling support frames, and a rotary driver. The pair of rotary drums are fixed at both ends of the furnace tube and are installed at the ends of the furnace body through the rolling support frames. The rotary driver is used to drive one of the rotary drums to rotate.

[0012] The rolling support frame includes a frame body and a pair of rollers that are rolled on both ends of the frame body via a rotating shaft. A rotating ring is fixed on the outer peripheral wall of the rotating cylinder, and the outer peripheral wall of the rotating ring is in rolling contact with each roller.

[0013] The rotary drive includes a drive motor, an output gear, a gear ring, and a chain. The drive motor is mounted on one end of the furnace body via a frame, and the output gear is mounted on its output shaft. The gear ring is fixed on the outer wall of one of the rotating drums and is connected to the output gear via a chain.

[0014] The rotary drive also includes a clamping gear, a clamping frame, and an adjusting screw. The adjusting screw is movably mounted on the frame through a screw hole. The clamping frame is slidably mounted on the frame and is movably connected to one end of the adjusting screw. The other end is provided with a clamping gear that abuts against the outside of the chain.

[0015] The feeding assembly is fixed on the frame, and a feeding platform is provided on the outside of the frame. A ladder is connected to one side of the feeding platform.

[0016] The nitrogen protection assembly includes a pair of connecting shells, each of which is sealed and fitted onto the outer end of the corresponding rotary drum and fixed to the outer wall of the furnace body via a frame. The top of each pair of connecting shells is connected to an external nitrogen supply device via a vent pipe.

[0017] The discharge end of the feeding component is sealed and inserted into the corresponding connecting shell, and the bottom of the other connecting shell has a discharge port.

[0018] The beneficial effects of this utility model are as follows:

[0019] This application utilizes a nitrogen protection assembly (including a sealed connecting shell and a circulating vent pipe) to create a completely inert atmosphere. Nitrogen is introduced from the top of the connecting shell and fills the furnace tubes. Combined with the sealing structure between the connecting shell, the rotating drum, and the feeding end, air infiltration is effectively prevented. This equipment can control the activated coke carbon loss rate to below 5%, while avoiding the generation of harmful gases from the combustion of organic matter. The activated coke adsorption capacity recovery rate after regeneration is increased to over 90%, significantly reducing activated coke oxidation loss and improving regeneration quality.

[0020] The inner wall of the furnace tube is equipped with spiral blades, which work in conjunction with the screw conveyor structure of the feeding assembly: when the spiral blades rotate with the furnace tube, they not only assist the material to tumble and be heated, but also forcefully guide the activated coke to move axially through the spiral thrust; the screw precisely controls the feeding rate to avoid a sudden increase in the accumulation of raw materials.

[0021] The rotary drive is equipped with a tensioning mechanism consisting of a clamping gear and an adjusting screw. The position of the clamping frame can be adjusted in real time by adjusting the screw, so that the chain is always kept taut. This avoids unstable rotation of the furnace tube caused by transmission slippage, reduces component wear, reduces the failure rate of continuous equipment operation, and extends the service life of core components (furnace tube and gear).

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The nitrogen-protected activated coke regeneration furnace equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] Example 1:

[0032] This application provides an activated coke regeneration furnace device with nitrogen protection, including a feeding component 1, a rotary kiln 2 and a nitrogen protection component 3. The feeding component 1 is used to feed the activated coke to be regenerated into the rotary kiln 2, and the nitrogen protection component 3 is used to circulate nitrogen into the rotary kiln 2. The rotary kiln 2 generates high-temperature carbonization of the organic matter attached to the activated coke to be regenerated.

[0033] like Figures 1 to 4 As shown, due to the aforementioned structure, the material conveying function of the feeding component 1 is first activated to accurately and stably feed the activated coke to be regenerated into the rotary kiln 2, providing a raw material basis for subsequent regeneration. Simultaneously, the nitrogen protection component 3 is activated, continuously circulating nitrogen into the rotary kiln 2 according to preset pressure and flow parameters. The nitrogen gradually fills the internal space of the rotary kiln 2, displacing the air (especially oxygen) already present in the furnace, forming a stable inert protective atmosphere. This prevents the activated coke to be regenerated from oxidizing with oxygen at high temperatures, and also prevents the combustion of organic matter in the furnace from producing harmful gases or affecting the regeneration effect. Subsequently, the rotary kiln 2 activates its high-temperature heating function, raising the furnace temperature to the preset range required for the carbonization reaction. The activated coke to be regenerated comes into full contact with the high-temperature environment in the nitrogen protective atmosphere, and the organic matter attached to its surface and interior undergoes carbonization and decomposition under high temperature, gradually detaching from the activated coke body, thus achieving the regeneration and activation of the activated coke. Throughout the process, the continuous feeding of the feeding component 1 ensures the continuity of the process, the circulating nitrogen supply of the nitrogen protection component 3 ensures the stability of the reaction environment, and the high temperature of the rotary kiln 2 is the core driving force for the carbonization of organic matter and the regeneration of activated coke. The three work together to complete the basic process of activated coke regeneration.

[0034] Example 2:

[0035] In this embodiment, in addition to the structural features of the aforementioned embodiments, the feeding assembly 1 includes a feeding bin 11, a feeding pipe 12, an auger 13 and a drive motor. The bottom of the feeding bin 11 is connected to the feeding pipe 12. The auger 13 is disposed in the feeding pipe 12 and is driven by the drive motor to feed the activated coke to be regenerated in the feeding pipe 12 into the rotary kiln 2.

[0036] like Figures 1 to 4 As shown, due to the adoption of the above structure, the structure of the feeding component 1 has been refined. While retaining the core process of "nitrogen protection + high-temperature carbonization in rotary kiln 2," its operating logic further optimizes the stability and controllability of material conveying. During operation, the activated coke to be regenerated is first fed into the feeding hopper 11 in batches. The feeding hopper 11, as a material storage container, can temporarily store raw materials and guides them to fall naturally into the feeding pipe 12 connected to the bottom through its own structure (such as a funnel-shaped bottom), avoiding material accumulation and blockage. Next, the drive motor is started, and the drive motor outputs power to drive the auger 13 to rotate inside the feeding pipe 12. The spiral blades of the auger 13 are tightly fitted with the inner wall of the feeding pipe 12, generating an axial pushing force on the activated coke to be regenerated inside the feeding pipe 12 during rotation, uniformly and quantitatively conveying the material along the feeding pipe 12 into the rotary kiln 2. Compared to traditional gravity feeding methods, the auger 13-driven conveying system can precisely control the material conveying volume by adjusting the speed of the drive motor. This avoids material accumulation in the rotary kiln 2 due to excessively high material flow rate, or insufficient material in the kiln due to excessively slow flow rate, which would affect processing efficiency. Simultaneously, the cooperation between the auger 13 and the feeding pipe 12 effectively prevents material from scattering during conveying, ensuring that all raw materials enter the rotary kiln 2 and improving material utilization. At this time, the rotary kiln 2 and the nitrogen protection component 3 still operate according to the logic of Example 1, with high-temperature carbonization and inert protection proceeding simultaneously. The refined structure of the feeding component 1 provides a more reliable material supply guarantee for the stable and efficient operation of the entire regeneration process.

[0037] Example 3:

[0038] In this embodiment, in addition to the structural features of the aforementioned embodiments, the rotary kiln 2 includes a furnace body 21, a furnace tube 22 with spiral blades on the inner wall, a heating unit 23, and a rotary drive unit 24. The furnace tube 22 is rotatably installed in the furnace body 21 through the rotary drive unit 24, and the heating unit 23 is located in the furnace body 21 for heating the furnace tube 22.

[0039] In this embodiment of the application, the rotary drive unit 24 includes a pair of rotary drums 241, a pair of rolling support frames 242, and a rotary driver 243. The pair of rotary drums 241 are respectively fixed at both ends of the furnace tube 22 and are all installed at the end of the furnace body 21 through the rolling support frames 242. The rotary driver 243 is used to drive one of the rotary drums 241 to rotate.

[0040] In this embodiment of the application, the rolling support frame 242 includes a frame body 2421 and a pair of rollers 2422 that are rotatably mounted at both ends of the frame body 2421 via a rotating shaft. A rotating ring 2423 is fixedly provided on the outer peripheral wall of the rotating cylinder 241, and the outer peripheral wall of the rotating ring 2423 is in rolling contact with each roller 2422. It also includes:

[0041] like Figures 1 to 4 As shown, due to the above-mentioned structure, the structure of rotary kiln 2 and the core rotary drive unit 24 and rolling support frame 242 has been refined, and the inner wall of the furnace tube 22 is equipped with spiral blades. The operating logic revolves around "improving the rotational stability of the furnace tube 22 and ensuring uniform heating and smooth passage of materials", further optimizing the regeneration effect and material conveying efficiency.

[0042] In the initial stage of operation, after the feeding component 1 feeds the activated coke to be regenerated into the furnace tube 22, the rotary drive unit 24 starts: first, the rotary driver 243 outputs power to drive one of the rotary drums 241 connected to it to rotate (the rotary drum 241 is fixedly connected to both ends of the furnace tube 22). Since the two rotary drums 241 are respectively installed at the ends of the furnace body 21 through the rolling support frame 242, when one of the rotary drums 241 rotates, it will drive the furnace tube 22 and the other rotary drum 241 to rotate synchronously. During the rotation of the rotary drum 241, the rolling support frame 242 plays a key supporting and guiding role: the frame 2421 of the support frame provides a fixed support foundation for the entire structure, and the rollers 2422 installed at both ends of the support frame make rolling contact with the rotating ring 2423 on the outer peripheral wall of the rotary drum 241 through the rotating shaft. This rolling contact method transforms the sliding friction between the rotary drum 241 and the support frame into rolling friction, which greatly reduces frictional resistance. This not only reduces component wear and extends the service life of the equipment, but also allows the rotary drum 241 to drive the furnace tube 22 to rotate more smoothly and steadily.

[0043] Simultaneously, the heating unit 23 starts and continuously transfers heat to the furnace tube 22, maintaining the internal temperature of the furnace tube 22 within the preset carbonization range. As the furnace tube 22 rotates slowly and steadily under the drive of the rotary drive unit 24, the spiral blades on its inner wall rotate synchronously with the furnace tube 22. On one hand, this assists in more thorough tumbling and mixing of the activated coke to be regenerated within the furnace tube 22, preventing uneven heating due to localized material accumulation. On the other hand, the spiral blades, through their spiral structure, generate axial guiding thrust on the activated coke, guiding it to move gradually along the length of the furnace tube 22. This effectively prevents the activated coke from stagnating and clogging within the furnace tube 22, ensuring that the material can smoothly pass through the entire furnace tube 22, fully contacting the high-temperature environment to complete the organic carbonization process. This improves the uniformity and overall quality of activated coke regeneration while ensuring the continuity of material transport.

[0044] Example 4:

[0045] In this embodiment, in addition to the structural features of the aforementioned embodiments, the rotary drive 243 includes a drive motor, an output gear 2431, a gear ring 2432, and a chain 2433. The drive motor is mounted on one end of the furnace body 21 via a frame, and the output gear 2431 is mounted on its output shaft. The gear ring 2432 is fixed on the outer wall of one of the rotary drums 241 and is connected to the output gear 2431 via the chain 2433.

[0046] In this embodiment of the application, the rotary drive 243 further includes a clamping gear 2434, a clamping frame 2435, and an adjusting screw 2436. The adjusting screw 2436 is movably mounted on the frame through a screw hole. The clamping frame 2435 is slidably mounted on the frame and is movably connected to one end of the adjusting screw 2436. The other end is provided with a clamping gear 2434 that abuts against the outside of the chain 2433.

[0047] In this embodiment of the application, the feeding component 1 is fixed on the frame, and the outer side of the frame is provided with a feeding platform 4, with a ladder 5 connected to one side of the feeding platform 4.

[0048] like Figures 1 to 4 As shown, due to the aforementioned structure, the rotary drive 243 has undergone functional optimization, and a feeding platform 4 and a ladder 5 have been added. The inner wall of the furnace tube 22 still has spiral blades. The operating logic focuses on "improving transmission stability, facilitating feeding operations, and ensuring smooth material passage." In the rotary drive stage, the drive motor is first started. The drive motor is fixed to one end of the furnace body 21 via a frame. Its output shaft drives the output gear 2431 to rotate. The output gear 2431 transmits power to the gear ring 2432 fixed to the outer wall of the rotary drum 241 via a chain 2433. The gear ring 2432 rotates with the chain 2433, thereby driving the rotary drum 241 and the furnace tube 22 to rotate synchronously, achieving stable rotation of the furnace tube 22. To prevent the chain 2433 from slipping, causing abnormal noise, or reducing transmission efficiency due to loosening during long-term transmission,

[0049] The added clamping structure in this embodiment works simultaneously: by rotating the adjusting screw 2436 (which is movably engaged with the screw hole on the frame), the clamping frame 2435, which is movably connected to one end of the adjusting screw 2436, slides on the frame. The clamping gear 2434 at the other end of the clamping frame 2435 moves outward from the chain 2433 until the clamping gear 2434 is in close contact with the outer side of the chain 2433, generating a continuous clamping force on the chain 2433, thus tensioning the chain 2433. This ensures that the output gear 2431, chain 2433, and gear ring 2432 always maintain a stable meshing transmission relationship, avoiding transmission failure and providing power guarantee for the stable rotation of the furnace tube 22 and the inner wall spiral blades.

[0050] When the furnace tube 22 rotates stably, the spiral blades on the inner wall operate synchronously. While assisting the activated coke to be regenerated to tumble and be heated, the spiral thrust guides the material to move smoothly along the axial direction of the furnace tube 22, preventing material stagnation and ensuring a continuous regeneration process. In the material supply stage, since the feeding component 1 is fixed on the frame, workers can safely and conveniently climb onto the feeding platform 4 via the ladder 5. The feeding platform 4 provides workers with a stable operating surface, facilitating the batch and efficient pouring of the activated coke to be regenerated into the unloading bin 11 of the feeding component 1. This solves the problem of inconvenience caused by the high position of the feeding component 1 during traditional feeding, reduces the labor intensity of feeding, and improves the safety and efficiency of feeding.

[0051] At this time, the nitrogen protection component 3 continuously supplies nitrogen, the heating unit 23 maintains the high temperature of the furnace tube 22, and the components work together. With the support of stable transmission, convenient feeding and spiral blades to assist material passage, the reliability, ease of operation and material conveying efficiency of the entire activated coke regeneration process are further improved.

[0052] Example 5:

[0053] In this embodiment, in addition to the structural features of the aforementioned embodiments, the nitrogen protection component 3 includes a pair of connecting shells 31. Each connecting shell 31 is respectively sealed and sleeved on the outer end of the corresponding rotary drum 241, and is fixedly connected to the outer wall of the furnace body 21 through a frame. The top of each pair of connecting shells 31 is connected to an external nitrogen supply device through a vent pipe.

[0054] In this embodiment of the application, the discharge end of the feeding component 1 is sealed and inserted into the corresponding connecting shell 31, and the bottom of the other connecting shell 31 is provided with a discharge port 32.

[0055] like Figures 1 to 4 As shown, due to the above structure, the structure and connection relationship of the nitrogen protection component 3 have been refined, and the inner wall of the furnace tube 22 is provided with spiral blades. The core of the operating logic is to "enhance the nitrogen sealing effect, realize the coordinated cooperation between material entry and exit and nitrogen protection, and ensure the smooth passage of materials". During operation, the external nitrogen supply equipment is first activated, and nitrogen is delivered to the top of a pair of connecting shells 31 through the vent pipe (the connecting shells 31 are respectively sealed and fitted on the outer end of the corresponding rotary drum 241, and fixed to the outer wall of the furnace body 21 through the frame). Since the connecting shell 31 and the rotary drum 241 adopt a sealed fitting structure, the nitrogen will form an inert space with a certain pressure inside the shell after entering the connecting shell 31. Then, the nitrogen will gradually enter the furnace tube 22 through the connecting channel between the rotary drum 241 and the furnace tube 22, filling the space of the furnace tube 22 and displacing the air to form a stable nitrogen protective atmosphere. At the same time, the sealing structure of the connecting shell 31 can effectively prevent nitrogen from leaking from the connection gap between the rotary drum 241 and the furnace body 21, ensuring that the nitrogen concentration in the furnace is maintained within the preset range and ensuring the protective effect.

[0056] In the material conveying process, the discharge end of the feeding component 1 is sealed and inserted into the corresponding connecting shell 31. This sealed insertion structure allows the activated coke to be regenerated to directly enter the nitrogen atmosphere inside the connecting shell 31 after being discharged from the feeding component 1, and then enter the furnace tube 22 through the rotary drum 241. When the furnace tube 22 rotates, the spiral blades on the inner wall generate axial thrust on the activated coke, guiding the activated coke to be regenerated to move smoothly along the furnace tube 22. This ensures that the material fully contacts the high temperature to complete carbonization, while also preventing the material from accumulating and blocking inside the furnace tube 22, ensuring smooth passage. After the activated coke completes carbonization and regeneration inside the furnace tube 22, it gradually moves to the other end of the furnace tube 22 under the continuous guiding action of the spiral blades, and finally exits the equipment through the discharge port 32 opened at the bottom of another connecting shell 31. Since this connecting shell 31 is also in a nitrogen-sealed atmosphere, the regenerated activated coke can also avoid contact with air during the discharge process, preventing secondary oxidation and ensuring the regeneration effect. Throughout the process, the connecting shell 31 achieves nitrogen sealing and material transition, while the spiral blades ensure smooth material transport. Together with other components, these two components enable nitrogen protection and material transport to run through the entire process of "material entry - furnace regeneration - material discharge," further enhancing the inert protection effect and process continuity, and improving the quality stability and transport efficiency of activated coke regeneration.
