Description

A highly stable fruit shell activated carbon activation device Technical Field

[0001] This invention relates to the field of activated carbon production equipment technology, specifically to a highly stable fruit shell activated carbon activation device. Background Technology

[0002] Coconut shell activated carbon is widely used in water treatment, air purification and other fields due to its well-developed pore structure and strong adsorption performance. The activation process in its production is a key step that determines the quality of the finished product. It usually requires the carbonized coconut shell to react with the activation medium at high temperature.

[0003] Existing activation devices are often simple in mechanical design, mostly using a single inclined plate or straight drop structure, which makes it easy for the fruit shell material to accumulate and flow off course when falling, making it difficult to ensure the uniformity of material heating. At the same time, traditional equipment cannot effectively control the residence time and contact area of ​​the material according to the intensity of the activation reaction at different stages, resulting in incomplete activation reaction and serious energy waste.

[0004] Therefore, those skilled in the art have provided a highly stable fruit shell activated carbon activation device to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a highly stable fruit shell activated carbon activation device, which solves the problems of uneven material heating, incomplete reaction, and low energy utilization in existing activation devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highly stable activated carbon activation device for fruit shells, comprising an activation furnace body and multiple inclined plates. The activation furnace body has two parallel partitions inside, dividing the inner cavity of the furnace body into a central material channel and two flues on either side. Multiple rectangular grooves are vertically arranged from top to bottom on the two partitions. Rectangular blocks are provided at both ends of the multiple inclined plates, and these blocks are inserted into the rectangular grooves of the corresponding partitions. The inclined plates on adjacent layers of rectangular blocks have opposite inclination directions and are staggered. Through this technical solution, the staggered arrangement of the inclined plates promotes material tumbling and dispersion to eliminate accumulation and uneven flow. The denser lower and sparser upper spacing precisely matches the intensity of the reaction and extends the residence time. Combined with the rapid convergence of exhaust gas through the hollow exhaust channels inside the inclined plates to maintain pressure balance, uniform heating and full reaction of the material are achieved. This results in highly efficient heat exchange while significantly improving the activation quality of the activated carbon, energy utilization, and device operating efficiency.

[0007] Furthermore, a hollow exhaust channel is provided inside the inclined plate, and an exhaust port is provided in the middle of the rectangular block. One end of the exhaust port is connected to the flue, and the other end is connected to the hollow exhaust channel inside the inclined plate. Through the above technical solution, a path is constructed to collect the flue gas after reaction in the material channel into the interior of the inclined plate and guide it to the flues on both sides, realizing the orderly collection and discharge of flue gas and maintaining the stable gas pressure in the material channel.

[0008] Furthermore, the bottom surface of the inclined plate is provided with a micro-perforated smoke exhaust port, which is connected to the hollow smoke exhaust channel. Through the above technical solution, the flue gas that has participated in the reaction in the material channel can enter the interior of the inclined plate through the micro-perforated smoke collection port, realizing the directional discharge of the flue gas, preventing the flue gas from accumulating in the material channel, and ensuring sufficient contact between heat and materials.

[0009] Furthermore, the material channel includes a feed port, a carbonization and activation section, and a discharge port connected sequentially from top to bottom, and the inclined plates are arranged in multiple layers within the carbonization and activation section; through the above technical solution, a segmented activation reaction space is constructed, and the movement path of the material in the key reaction area is extended by the multiple inclined plates, ensuring sufficient time required for the activation reaction.

[0010] Furthermore, the vertical spacing between adjacent inclined plates located in the carbonization activation section gradually decreases from top to bottom; through the above technical solution, the distribution density of inclined plates in the lower high-temperature activation zone is increased, thereby slowing down the falling speed of the material in the lower region, prolonging the residence time of the material in the high-temperature zone, and improving the fullness of the reaction.

[0011] Furthermore, the rectangular block and the rectangular groove are detachably connected, and a high-temperature resistant sealing layer is provided between the side wall of the rectangular block and the inner wall of the rectangular groove. Through the above technical solution, it is not only convenient to quickly replace and maintain the worn or blocked inclined plate assembly, but also to effectively prevent the leakage of high-temperature flue gas, thus ensuring the sealing performance and operational stability of the device.

[0012] Furthermore, the upper surface of the inclined plate is coated with a silicon carbide wear-resistant coating; through the above technical solution, the excellent wear resistance and high temperature resistance of silicon carbide material are utilized to effectively reduce the mechanical wear of the inclined plate surface during the long-term sliding process of the fruit shell material, and significantly extend the service life of the inclined plate.

[0013] This invention provides a highly stable activated carbon activation device using fruit shells. It offers the following advantages: 1. This invention provides a highly stable activated carbon activation device using fruit shells. By setting inclined plates with opposite and staggered directions within the material channel, the material continuously rotates and fully disperses during its descent, effectively eliminating material accumulation and flow deviation defects during descent. This achieves uniform contact between the material and the activation medium, significantly improving the activation uniformity of the activated carbon and the quality of the finished product.

[0014] 2. This invention provides a highly stable activated carbon activation device for fruit shells. By designing the vertical spacing between two adjacent inclined plates to gradually decrease from top to bottom, it precisely adapts to the intensity of the activation reaction at different stages. The high-density inclined plates at the bottom slow down the falling of materials and increase the contact area, thereby ensuring that the reaction proceeds fully and avoiding energy waste, significantly improving the energy utilization rate of the device.

[0015] 3. This invention provides a highly stable activated carbon activation device for fruit shells. By constructing a hollow flue gas channel inside the inclined plate and cooperating with a microporous flue gas collection port, the flue gas after the reaction can be quickly gathered and discharged from the flues on both sides, thereby maintaining the gas pressure balance in the furnace and preventing the flue gas from accumulating and hindering the material from falling. While realizing the full utilization of thermal energy, it significantly improves the processing throughput and operating efficiency of the device. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Embodiment 1:

[0019] As shown in Figures 1-5, this embodiment of the invention provides a highly stable activated carbon activation device for fruit shells, including an activation furnace body 1 and multiple inclined plates 6. The activation furnace body 1 has two parallel partitions 2 inside, which divide the inner cavity of the activation furnace body 1 into a material channel 5 in the middle and two flues 4 on both sides. Multiple rectangular grooves 3 are formed vertically from top to bottom on the two partitions 2. Rectangular blocks 7 are set at both ends of the multiple inclined plates 6, and the rectangular blocks 7 are inserted into the rectangular grooves 3 of the corresponding partitions 2. The inclined plates 6 on the upper and lower adjacent layers of rectangular blocks 7 have opposite inclination directions and are staggered. The staggered arrangement of the inclined plates 6 promotes the material to turn and disperse to eliminate accumulation and flow deviation. The denser spacing structure at the bottom and sparser at the top is precisely adapted to the intensity of the reaction and prolongs the residence time. Combined with the hollow exhaust channels 61 inside the inclined plates 6, the exhaust gas is quickly gathered to maintain the gas pressure balance, thereby achieving uniform heating and full reaction of the material. While achieving efficient heat exchange, it significantly improves the activation quality of activated carbon, energy utilization rate and device operating efficiency.

[0020] A hollow exhaust channel 61 is provided inside the inclined plate 6, and an exhaust port 71 is provided in the middle of the rectangular block 7. One end of the exhaust port 71 is connected to the flue 4, and the other end is connected to the hollow exhaust channel 61 inside the inclined plate 6. This creates a path for the flue gas after reaction in the material channel 5 to be collected inside the inclined plate 6 and guided to the flues 4 on both sides, realizing the orderly collection and discharge of flue gas and maintaining the stable air pressure in the material channel 5. A micro-perforated exhaust port 62 is provided on the bottom surface of the inclined plate 6. The micro-perforated exhaust port 62 is connected to... The hollow exhaust channel 61 is connected, allowing the flue gas that has participated in the reaction in the feed channel 5 to enter the interior of the inclined plate 6 through the microporous flue gas collection port, realizing the directional discharge of flue gas and preventing the flue gas from accumulating in the feed channel 5. At the same time, it ensures sufficient contact between heat and materials. The feed channel 5 includes a feed port 52, a carbonization activation section 51, and a discharge port 53 connected sequentially from top to bottom. The inclined plate 6 is arranged in multiple layers in the carbonization activation section 51, constructing a segmented activation reaction space. Through the extension of the multiple layers of inclined plate 6... The extended material movement path in the critical reaction zone ensures sufficient time for the activation reaction. The vertical spacing between adjacent inclined plates 6 in the carbonization activation section 51 gradually decreases from top to bottom, increasing the distribution density of inclined plates 6 in the lower high-temperature activation zone. This slows down the falling speed of the material in the lower region, prolongs the residence time of the material in the high-temperature zone, and improves the sufficiency of the reaction. The rectangular block 7 and the rectangular groove 3 are detachably connected, and a high-temperature resistant sealing layer is provided between the side wall of the rectangular block 7 and the inner wall of the rectangular groove 3. This facilitates quick replacement and maintenance of worn or clogged inclined plate 6 components and effectively prevents leakage of high-temperature flue gas, ensuring the sealing performance and operational stability of the device. The upper surface of the inclined plate 6 is coated with a silicon carbide wear-resistant coating. Utilizing the excellent wear resistance and high-temperature resistance of silicon carbide material, the mechanical wear on the surface of the inclined plate 6 during long-term sliding of the nut shell material is effectively reduced, significantly extending the service life of the inclined plate 6.

[0021] Working principle: First, the nutshell material enters the carbonization and activation section 51 of the feed channel 5 through the feed port 52, and flows downward along the multi-layered inclined plates 6 under the action of gravity. Due to the opposite inclination direction of adjacent inclined plates 6, the material will flip and be re-distributed when transferring between layers, which will disrupt the accumulation and flow deviation of the material and make it evenly spread on the inclined plates 6. At the same time, the structure of the inclined plates 6 with the gradually decreasing spacing from top to bottom will reduce the flow cross section of the lower channel and increase the flow resistance, forcing the material flow velocity to decrease and prolong its residence time in the high temperature zone.

[0022] During the activation reaction, the externally introduced high-temperature activation medium undergoes heat exchange and chemical reaction with the nut shell material in the material channel 5. The flue gas generated after the reaction is drawn into the hollow exhaust channel 61 inside the inclined plate 6 through the micro-perforated smoke collection port opened on the bottom surface of the inclined plate 6 during the flow process. The flue gas flowing through the channel transfers heat to the wall surface of the inclined plate 6 by thermal convection. Then, the flue gas flows along the hollow exhaust channel 61 to the rectangular blocks 7 at both ends, and is discharged into the flues 4 on both sides through the smoke outlet 71.

[0023] The following points should be noted in this article: 1. The accompanying drawings of the embodiments disclosed herein only involve structures related to the embodiments disclosed herein; other structures can be referred to in the usual design.

[0024] 2. Where there is no conflict, the embodiments of this disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
