Description

Technical Field

[0001] The present invention relates to the technical field of activated carbon regeneration, and particularly to a waste activated carbon activation and regeneration manufacturing device and a manufacturing method thereof. Background Art

[0002] The activation and regeneration of waste activated carbon refers to the process of restoring the adsorption performance of used activated carbon by means of specific technical means, so as to achieve resource utilization and obtain environmental protection benefits. This process covers a variety of methods and technologies, and according to different requirements and conditions, physical, chemical or physical-chemical combined methods can be used for regeneration.

[0003] Common waste activated carbon activation and regeneration methods include thermal regeneration method, steam method, electrochemical regeneration method, wet oxidation method, etc. Among them, the thermal regeneration method is the most widely used and technically mature waste activated carbon regeneration method at present. Its core principle is that through high-temperature heating, the organic matter in the activated carbon is decomposed and desorbed, thereby restoring its adsorption capacity.

[0004] Common heating regeneration devices include multi-layer type, rotary type, fluidized bed type and moving bed type, etc. Among them, the multi-layer heating regeneration device is also called a vertical multi-stage regeneration furnace or a multi-layer rake furnace. Its working principle is to use natural gas or oil as the fuel source and use water vapor for activation operation. During specific operation, waste activated carbon is transported into the device from the top of the furnace body. Subsequently, the waste activated carbon is gradually pushed to the next layer by the rotating rake arm. During this process of gradually falling layer by layer, the waste activated carbon continuously interacts with the high-temperature environment and water vapor, and finally realizes activation and regeneration.

[0005] However, the existing multi-layer heating regeneration device also has some problems in actual use: In the multi-layer heating regeneration device, the material moves downward by the push of the rake arm, while the air flow flows along an S-shaped path due to the influence of the internal structure of the device and the ventilation design. This inconsistency in the movement trajectory makes it difficult for the material and the air flow to fully contact in some areas, thus reducing the mass transfer and heat transfer effect between the material and the air flow to a certain extent. Poor mass transfer and heat transfer effect will cause the organic matter adsorbed inside the waste activated carbon to be unable to fully react with the activation medium in the air flow, affecting the desorption efficiency and further affecting the regeneration efficiency of the waste activated carbon. Summary of the Invention

[0006] Based on this, in view of the problem of low regeneration efficiency existing in the current waste activated carbon regeneration process, it is necessary to provide a waste activated carbon activation and regeneration manufacturing device and a manufacturing method thereof.

During the use of the device for activating and regenerating waste activated carbon, first, the waste activated carbon is placed on the top of the uppermost adjustment carrier plate, and then steam and gas are continuously introduced into the furnace body. The steam and gas move upward from bottom to top through the first, second, and third guide holes, and transfer heat and mass with the waste activated carbon. Subsequently, the central shaft rotates, driving the static carrier plate and the moving carrier plate to operate, and using the rake component to level the waste activated carbon. Then, the central shaft rotates and vertically moves upward, and the adjustment component increases the communication area between the first guide hole and the third guide hole, so that the waste activated carbon falls from the static carrier plate to the moving carrier plate through the two holes from top to bottom. At this time, the transmission paths of the waste activated carbon and the gas flow are the same, and because the moving carrier plate is close to the static carrier plate, on the one hand, the falling distance of the waste activated carbon is short, so that the situation of being broken can be effectively alleviated. On the other hand, the chamber between the moving carrier plate and the static carrier plate decreases and the pressure increases, and under the action of the pressure difference, the gas can dredge the blocked parts of the first, second, and third guide holes, so that the flow efficiency of the gas can be guaranteed. After that, the central shaft rotates and vertically moves downward, the adjustment component reduces the communication area between the first and third guide holes, and increases the communication area between the second and third guide holes, so that the waste activated carbon on the moving carrier plate falls to the static carrier plate from top to bottom through the second and third guide holes, and the transmission paths of the steam and gas still remain the same, which helps to improve the heat and mass transfer effect and the regeneration efficiency. At the same time, the short falling distance can alleviate the phenomenon of the waste activated carbon being broken, which helps to improve the regeneration quality. Description of the Drawings

[0064] like Figures 1 to 13As shown in the figure, the waste activated carbon activation and regeneration manufacturing device provided by the embodiment of the present invention is used for regenerating waste activated carbon, and is configured to include a furnace body 1, a central shaft 2, a static load disk 3, a dynamic load disk 4, an adjustment disk 5, an adjustment component, and a rake component 7. The central shaft 2 is vertically inserted into the furnace body 1, and can rotate around its own axis and move along its own axis direction; the static load disk 3 is sleeved on the central shaft 2, and can rotate synchronously with the central shaft 2 and slide axially relative to the central shaft 2. There are multiple static load disks 3, and the multiple static load disks 3 are arranged at intervals along the axis direction of the central shaft 2. Each static load disk 3 has a first guide hole 301; the dynamic load disk 4 is fixedly sleeved on the central shaft 2. There are multiple dynamic load disks 4, and the dynamic load disks 4 and the static load disks 3 are arranged alternately along the axis direction of the central shaft 2. Each dynamic load disk 4 has a second guide hole 401; an adjustment disk 5 is provided on the top of each static load disk 3 and dynamic load disk 4. The adjustment disk 5 is sleeved on the central shaft 2 and can rotate relative to the static load disk 3 or the dynamic load disk 4. Each adjustment disk 5 has a third guide hole 501, and the third guide hole 501 communicates with the first guide hole 301 or the second guide hole 401; the adjustment component is configured to drive the adjustment disk 5 to rotate relative to the static load disk 3 when the central shaft 2 moves upward in the vertical direction, so as to increase the communication area between the first guide hole 301 and the third guide hole 501; when the central shaft 2 moves downward in the vertical direction, it can not only drive the adjustment disk 5 to rotate relative to the static load disk 3 to reduce the communication area between the first guide hole 301 and the third guide hole 501, but also drive the adjustment disk 5 to rotate relative to the dynamic load disk 4 to increase the communication area between the second guide hole 401 and the third guide hole 501; the rake component 7 is configured to be able to flatten the waste activated carbon on the adjustment disk 5.

[0065] Specifically, in this embodiment, the structures of the static load disk 3 and the dynamic load disk 4 are the same; in order to facilitate the input of waste activated carbon into the furnace body 1, a feeding port 101 is opened at the top of the furnace body 1; in order to facilitate the discharge of the regenerated activated carbon inside the furnace body 1, a discharge port 102 is opened at the bottom of the furnace body 1; in order to facilitate the introduction of steam into the furnace body 1, an air inlet 103 is opened on the circumferential side wall at the bottom of the furnace body 1; in order to facilitate the discharge of waste gas, an air outlet 104 is opened at the top of the furnace body 1; in order to facilitate the introduction of gas into the furnace body 1, a burner 105 is provided on the circumferential side wall at the bottom of the furnace body 1; in order to facilitate the installation of the furnace body 1, a bracket 106 is provided at the bottom of the furnace body 1, and the bracket 106 supports on the ground during use.

[0066] To facilitate the synchronous rotation between the static load disk 3 and the central shaft 2, a sliding key fit is provided between the static load disk 3 and the central shaft 2. Optionally, a third sliding groove is provided on the inner peripheral wall of the static load disk 3, and the third sliding groove extends in a direction parallel to the axis of the static load disk 3. A first flat key is inserted on the circumferential side wall of the central shaft 2, and the first flat key extends in a direction parallel to the axis of the central shaft 2. And during installation, it is slidably inserted into the third sliding groove to ensure that when the central shaft 2 rotates, the static load disk 3 can be driven to rotate synchronously through the cooperation between the first flat key and the third sliding groove.

[0067] Furthermore, to facilitate the installation of the static load disk 3, a plurality of first clamping portions 8 are fixedly provided on the inner peripheral wall of the furnace body 1. The plurality of first clamping portions 8 are arranged at intervals along the axis direction of the central shaft 2, and the first clamping portions 8 clamp on both sides of the static load disk 3.

[0068] Specifically in this embodiment, when the number of static load disks 3 is set to two, the number of first clamping portions 8 is correspondingly set to two; the first clamping portion 8 can be set to have two first base rings 801. The two first base rings 801 are both coaxial and fixedly provided on the inner peripheral wall of the furnace body 1. The two first base rings 801 are arranged at intervals along the axis direction of the furnace body 1, so that a clamping area for placing the static load disk 3 can be formed between the two first base rings 801.

[0069] To facilitate the installation and adjustment of the adjustment disk 5, the waste activated carbon activation and regeneration manufacturing device is further provided with a plurality of clip pieces 13. The plurality of clip pieces 13 are divided into multiple groups. The clip pieces 13 in the same group are arranged between the static load disk 3 or the moving load disk 4 and the adjustment disk 5 on the same layer; the clip piece 13 is set to a Z-shaped structure, and one end is fixedly provided on the top of the static load disk 3 or the moving load disk 4, and the other end is arranged on the top of the adjustment disk 5 and forms a rotational fit with the adjustment disk 5.

[0070] Optionally, to facilitate the rotational fit between the clip piece 13 and the adjustment disk 5, a second flat key is provided at the bottom of the end of the clip piece 13 close to the adjustment disk 5. The second flat key is set to an inverted T-shaped structure. A circular groove is coaxially opened on the top of the adjustment disk 5, and the cross-sectional shape of the circular groove is set to an inverted T-shaped. The second flat key is slidably inserted into the circular groove during installation to ensure that the moving load disk 4 and the adjustment disk 5 can not only move synchronously along the axial direction, but also rotate relative to each other, and the static load disk 3 and the adjustment disk 5 can rotate relative to each other.

[0071] Optionally, the clip pieces 13 can be set in pairs.

[0072] Optionally, the two clip pieces 13 in the same group can be set to be staggered by 180 degrees during installation.

[0073] Exemplarily, the number of static load plates 3 and dynamic load plates 4 can be set to two, and from top to bottom, they are static load plate 3, dynamic load plate 4, static load plate 3, dynamic load plate 4; matchingly, the number of adjustment load plates 5 is set to four, and they are located on the top of the static load plate 3 and the dynamic load plate 4 respectively.

[0074] During use, the waste activated carbon is first placed on the top of the static load plate 3 located at the top through the feed port 101; then steam is continuously introduced into the furnace body 1 through the air inlet 103. Steam, as an important reaction medium, participates in the regeneration reaction of the waste activated carbon. Gas is continuously introduced into the furnace body 1 through the burner 105. The gas is fully burned in the furnace body 1, providing the necessary high-temperature environment for the entire activation and regeneration process; at the same time, steam and gas move upward from bottom to top through the first guide hole 301, the second guide hole 401 and the third guide hole 501. In this process, the steam and gas are in full contact with the waste activated carbon, and heat and mass transfer are carried out, so that the organic matter adsorbed inside the waste activated carbon begins to decompose and desorb.

[0075] Subsequently, the central shaft 2 is driven to rotate, and the central shaft 2 drives the static load plate 3 and the dynamic load plate 4 to rotate; during the rotation of the static load plate 3 and the dynamic load plate 4, the rake assembly 7 starts to work, and it flattens the waste activated carbon on the adjustment load plate 5 according to a preset method and frequency, so that the waste activated carbon is more evenly distributed on the static load plate 3 and the dynamic load plate 4, increasing the contact area between the waste activated carbon and the steam and gas, and further improving the heat and mass transfer effect.

[0076] Next, the central shaft 2 is controlled to rotate while moving upward in the vertical direction. During the upward movement of the central shaft 2, the adjustment component drives the adjustment carrier plate 5 to rotate relative to the static carrier plate 3, gradually increasing the connection area between the first guide hole 301 and the third guide hole 501; when the connection area increases to a certain extent, the waste activated carbon on the static carrier plate 3 passes through the first guide hole 301 and the third guide hole 501 from top to bottom under the action of gravity and falls onto the dynamic carrier plate 4; at this time, the waste activated carbon and the gas transmission path overlap, further enhancing the heat and mass transfer effect, which is conducive to improving the regeneration efficiency; moreover, since the dynamic carrier plate 4 is in the process of moving the central shaft 2 Moving in the direction close to the static loading plate 3 greatly reduces the falling distance of the waste activated carbon. On the one hand, it effectively alleviates the breakage of the waste activated carbon during the falling process, ensures the integrity of the activated carbon particles, and is conducive to improving the regeneration quality. On the other hand, the chamber space between the dynamic loading plate 4 and the static loading plate 3 is reduced, and the internal pressure is increased. Under the action of the pressure difference, the gas can clear the blockages of the first guide hole 301, the second guide hole 401 and the third guide hole 501, ensuring that the gas can flow smoothly and ensuring the stable progress of the heat and mass transfer process.

[0077] Afterwards, the central shaft 2 is controlled to rotate while moving vertically downward. During this downward movement, the adjustment assembly drives the adjustment plate 5 to rotate relative to the static plate 3, reducing the area of communication between the first and third guide holes 301, 501, to prepare for the subsequent addition of new waste activated carbon. It also drives the adjustment plate 5 to rotate relative to the dynamic plate 4, increasing the area of communication between the second and third guide holes 401, 501. When the area of communication between the second and third guide holes 401, 501 increases to an appropriate level, the waste activated carbon on the dynamic plate 4, under the action of gravity, flows downward through the second and third guide holes 401, 501, and falls to the static plate 3. During this process, the steam and gas continue to move upward, coinciding with the transfer path of the waste activated carbon. This further enhances heat and mass transfer, improving regeneration efficiency. Furthermore, the shorter descent distance continues to mitigate the breakage of the waste activated carbon, contributing to improved quality of the regenerated activated carbon.

[0078] Then, the waste activated carbon is placed on the top of the static loading plate 3 located at the top through the feed port 101, and the central shaft 2 is rotated and moved up or down while rotating, so that the waste activated carbon continuously and alternately falls between the static loading plate 3 and the dynamic loading plate 4, fully undergoing heat and mass transfer reactions with the steam and gas, and gradually completing the activation and regeneration process.

[0079] Finally, the regenerated activated carbon is discharged through the discharge port 102 opened at the bottom of the furnace body 1, and can be put back into the relevant adsorption work after collection; the waste gas generated by the reaction is discharged through the outlet 104 and is treated accordingly to meet environmental protection requirements.

[0080] In some embodiments, the first guide hole 301 , the second guide hole 401 , and the third guide hole 501 are all configured as spiral line structures.

[0081] Specifically in this embodiment, initially, the second guide hole 401 and the third guide hole 501 are in a partially connected state, such as Figure 9 As shown, the first guide hole 301 and the third guide hole 501 are in a partially connected state. At this time, the connection between the second guide hole 401 and the third guide hole 501, and the connection between the first guide hole 301 and the third guide hole 501 can only pass steam and gas, so that the waste activated carbon can stay in the current layer to meet the residence time requirements of the waste activated carbon at different activation stages; when the central axis 2 moves downward, under the action of the adjustment component, the second guide hole 401 and the third guide hole 501 are in a fully connected state. When the central axis 2 moves upward, under the action of the adjustment component, as shown Figure 10As shown, the first guide hole 301 and the third guide hole 501 are in a completely connected state. At this time, the connection between the second guide hole 401 and the third guide hole 501, and the connection between the first guide hole 301 and the third guide hole 501 can both pass steam, gas, and spent activated carbon, enabling the spent activated carbon to move to the next layer to switch the activation stage of the spent activated carbon.

[0082] Furthermore, collection hoppers are provided on each static load plate 3 and dynamic load plate 4. The collection hoppers are arranged at the end close to the first guide hole 301 or the second guide hole 401, and are configured to collect spent activated carbon with a size smaller than a preset value.

[0083] Specifically in this embodiment, when the connection between the third guide hole 501 and the second guide hole 401 is located inside, the collection hopper is located at the inner end of the second guide hole 401. As Figure 8 shown, at this time, the second guide hole 401 and the third guide hole 501 are in a partially connected state. Steam and gas mainly move inward along the arrow direction shown from the connection between the second guide hole 401 and the third guide hole 501, thereby driving the spent activated carbon with a size smaller than the preset value to move to the collection hopper along the spiral channel on the adjustment load plate 5. While achieving the unified collection of the spent activated carbon with a size smaller than the preset value on the dynamic load plate 4, it helps to reduce the impact on the regeneration process of the spent activated carbon with normal size. Similarly, when the connection between the third guide hole 501 and the first guide hole 301 is located inside, the collection hopper is located at the inner end of the first guide hole 301, thereby enabling the collection of the spent activated carbon with a size smaller than the preset value on the static load plate 3.

[0084] Optionally, the preset value is set such that the thickness of the spent activated carbon is less than the thickness of the adjustment load plate 5, thereby reducing the probability that the spent activated carbon with a size smaller than the preset value is pushed by the raking component 7, avoiding the spent activated carbon with a size smaller than the preset value being pushed too dispersedly. At the same time, the width of the spent activated carbon is greater than the connection width between the first guide hole 301 and the third guide hole 501 and between the second guide hole 401 and the third guide hole 501 when they are in a partially connected state, preventing the spent activated carbon from directly falling to the next layer of the dynamic load plate 4 or the static load plate 3 through the connection between the first guide hole 301 and the third guide hole 501 or the connection between the second guide hole 401 and the third guide hole 501, and avoiding the situation of non - collection.
