Description

Technical Field

[0001] This utility model relates to the field of activated carbon carbonization technology, specifically to an activated carbon carbonization reaction device with a circulating cooling structure. Background Technology

[0002] The preparation of activated carbon typically involves two main steps: carbonization (also known as carbonization) and activation. Carbonization is the process of heating raw materials (such as wood, coconut shells, coal, fruit shells, etc.) under oxygen-deficient conditions to remove volatile components and leave carbon-rich solid residues. This process usually uses activated carbon carbonization reactors.

[0003] However, current activated carbon carbonization reactors with circulating cooling structures still have the following shortcomings: many activated carbon carbonization reactors are not equipped with circulating cooling structures, which leads to a large amount of heat loss into the environment, resulting in energy waste. At the same time, in order to maintain the necessary operating conditions, additional energy may be required for heating or adjusting process parameters. Moreover, if the device temperature is too high, it may lead to excessive pyrolysis of the raw materials, generating excessive tar and gaseous byproducts, reducing the yield and quality of activated carbon. If the temperature is insufficient, it will slow down the carbonization process and affect production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an activated carbon carbonization reaction device with a circulating cooling structure, which can make the temperature distribution within the device more uniform.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon carbonization reaction device with a circulating cooling structure, comprising a carbonization reaction device, a jacket formed within the carbonization reaction device, and a carbonization furnace body installed within the carbonization reaction device. A first heat transfer ring is fixedly connected to the outer wall of the discharge end of the carbonization furnace body within the jacket, and a second heat transfer ring is fixedly connected to the outer wall of the middle section of the carbonization furnace body within the jacket. A first mounting groove and a second mounting groove are respectively formed at the opposite ends of the first heat transfer ring and the second heat transfer ring, and the same first heat pipe is fixedly connected to the first mounting groove and the second mounting groove.

[0006] Furthermore, a third heat transfer ring is fixedly connected to the outer wall of the feeding end of the carbonization furnace body within the interlayer. The opposite ends of the third heat transfer ring and the second heat transfer ring are respectively provided with a third mounting groove and a fourth mounting groove. The second mounting groove and the third mounting groove are not connected to each other. The third mounting groove and the fourth mounting groove are fixedly connected to the same second heat pipe.

[0007] Furthermore, the exposed outer walls of both the first heat pipe and the second heat pipe are fitted with protective sleeves. The evaporation end of the first heat pipe is located at the discharge end of the carbonization reaction device, the condensation end of the first heat pipe is located in the middle section of the carbonization reaction device, the evaporation end of the second heat pipe is located in the middle section of the carbonization reaction device, and the condensation end of the second heat pipe is located at the feed end of the carbonization reaction device.

[0008] Furthermore, a heat transfer elastic protective pad is fixed to one end surface of the third heat transfer ring located at the feed end of the carbonization reaction device.

[0009] Furthermore, multiple uniformly distributed ceramic springs are fixed to the annular outer walls of the first heat transfer ring, the second heat transfer ring, and the third heat transfer ring.

[0010] Furthermore, the ceramic springs on the outer walls of the first heat transfer ring, the second heat transfer ring, and the third heat transfer ring, which are on the same horizontal plane, have one end fixed to the same ceramic pad at the end away from the heat transfer elastic protective pad.

[0011] Furthermore, the surface of the ceramic pad is adapted to fit and rotatably connected to the inner wall of the interlayer, and both the surface of the ceramic pad and the inner wall of the interlayer are smoothly disposed.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, through the cooperation of the first heat transfer ring, the second heat transfer ring, and the first heat pipe, enables the device to achieve better heat transfer efficiency. In actual operation, most of the heat can flow back from the discharge end to the inside of the device. This design not only reduces the loss of heat to the external environment, but also promotes a more uniform distribution of heat inside the device, thereby reducing the occurrence of phenomena such as local overheating or local overcooling that are detrimental to the stable operation of the device and product quality. The structure is simple, easy to operate, and highly practical.

[0014] This invention utilizes the coordinated operation of a first heat transfer ring, a second heat transfer ring, a third heat transfer ring, a first heat pipe, and a second heat pipe. During the operation of the carbonization reactor, the heat dissipated at the discharge end is captured and absorbed by the first heat pipe. This heat is then guided and distributed. Part of the heat is fed back into the central region of the carbonization furnace and reintegrated into the reactor, providing continuous thermal support for the reaction process. The other part of the heat is further collected by the second heat pipe and transported to the feed end of the carbonization reactor. Here, the heat is released to preheat the raw materials about to enter the reactor. This design not only increases the initial temperature of the raw materials but also improves the overall efficiency of the reactor, achieving multiple uses of energy. Furthermore, the multiple protections provided by the heat transfer elastic protective pad, ceramic spring, and ceramic plate enhance the service life of the first and second heat pipes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1 to 6 As shown, the activated carbon carbonization reaction device with a circulating cooling structure includes a carbonization reaction device 1, a jacket 3 opened in the carbonization reaction device 1, and a carbonization furnace body 2 installed in the carbonization reaction device 1. The outer wall of the discharge end of the carbonization furnace body 2 is fixedly connected to a first heat transfer ring 4 in the jacket 3. The outer wall of the middle section of the carbonization furnace body 2 is fixedly connected to a second heat transfer ring 5 in the jacket 3. The opposite ends of the first heat transfer ring 4 and the second heat transfer ring 5 are respectively provided with a first mounting groove 7 and a second mounting groove 8. The same first heat pipe 11 is fixedly connected in the first mounting groove 7 and the second mounting groove 8.

[0024] like Figures 1 to 6As shown, in the activated carbon carbonization reactor with circulating cooling structure of this utility model, when in use, the heat from the discharge end of the carbonization reactor 1 is transferred to the first heat pipe 11 through the first heat transfer ring 4. This prevents the heat from directly contacting the first heat pipe 11, reducing damage to the first heat pipe 11. Subsequently, the heat is absorbed by the evaporation end of the first heat pipe 11. At this time, the liquid working fluid inside absorbs heat and turns into steam. Then, the steam flows to the condensation end of the first heat pipe 11 (usually the end with a lower temperature), where it releases heat and re-condenses into liquid. Subsequently, through the capillary action of the special structure (such as capillary structure) on the inner wall of the first heat pipe 11, the condensed liquid working fluid returns to the evaporation section to maintain circulation, achieving automatic reflux and forming a non-powered circulation. This overall process can achieve better heat transfer efficiency. Compared with the traditional solid metal heat conduction method, the heat pipe can transfer heat better with a smaller temperature difference, making the temperature distribution in the carbonization furnace 2 more uniform and reducing the occurrence of local overheating or overcooling. At the same time, it can also reduce excessive heat loss at the discharge end.

[0025] It should be noted that both the first heat pipe 11 and the second heat pipe 12 are filled with a phase change working fluid (such as water, ammonia or acetone) and have built-in capillary structures (such as a copper sintered powder layer or metal mesh). Manufacturers can select appropriate phase change working fluids and capillary structures for manufacturing according to actual conditions.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a third heat transfer ring 6 is fixedly connected to the outer wall of the feeding end of the carbonization furnace body 2 within the interlayer 3. The opposite ends of the third heat transfer ring 6 and the second heat transfer ring 5 are respectively provided with a third mounting groove 9 and a fourth mounting groove 10. The second mounting groove 8 and the third mounting groove 9 are not connected to each other. The third mounting groove 9 and the fourth mounting groove 10 are fixedly connected to the same second heat pipe 12.

[0027] Specifically, with the assistance of the first heat pipe 11 and the second heat pipe 12, the heat in the carbonization reactor 1 is first absorbed by the evaporation end of the first heat pipe 11 from the discharge end of the carbonization reactor 1, and then released from the condensation end of the first heat pipe 11. Subsequently, this heat is transferred by the second heat transfer ring 5. Part of it enters the middle section of the carbonization furnace body 2 to heat the middle section of the carbonization furnace body 2 and return the heat to the carbonization furnace body 2. The other part is absorbed by the evaporation end of the second heat pipe 12, and then released at the condensation end and enters the feed end of the carbonization reactor 1 to preheat the raw materials entering the feed end. This achieves the recycling and use of heat, reduces energy waste, and enhances the working efficiency of the carbonization reactor 1.

[0028] like Figures 1-6As shown, the exposed outer walls of the first heat pipe 11 and the second heat pipe 12 are both covered with protective sleeves. The evaporation end of the first heat pipe 11 is located at the discharge end of the carbonization reaction device 1, and the condensation end of the first heat pipe 11 is located in the middle section of the carbonization reaction device 1. The evaporation end of the second heat pipe 12 is located in the middle section of the carbonization reaction device 1, and the condensation end of the second heat pipe 12 is located at the feed end of the carbonization reaction device 1. This design allows the heat inside the device to be continuously recycled, making the heat distribution more uniform and reducing energy waste.

[0029] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a heat transfer elastic protective pad 13 is fixed to one end surface of the third heat transfer ring 6 located at the feed end of the carbonization reaction device 1.

[0030] Specifically, the end of the second heat pipe 12 at the feed end of the carbonization reaction device 1 can be protected to reduce the impact force on the second heat pipe 12 when the material enters the carbonization furnace body 2, making the device more durable.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, multiple uniformly distributed ceramic springs 14 are fixed to the annular outer walls of the first heat transfer ring 4, the second heat transfer ring 5, and the third heat transfer ring 6.

[0032] Specifically, by setting the ceramic spring 14, the first heat pipe 11 and the second heat pipe 12 can be supported, and at the same time, the impact from the outside can be buffered.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, one end of the ceramic spring 14 on the outer wall of the first heat transfer ring 4, the second heat transfer ring 5, and the third heat transfer ring 6, which are on the same horizontal plane, is fixed to the same ceramic pad 15 at the end away from the heat transfer elastic protective pad 13.

[0034] Specifically, by setting the ceramic pad 15, the ceramic spring 14 can be prevented from directly impacting the inner wall of the interlayer 3 after being subjected to force. This can protect one end of the carbonization reaction device 1 and also provide some protection for the ceramic spring 14.

[0035] It should be noted that an elastic, high-temperature resistant buffer pad should also be provided at the connection between the ceramic pad 15 and the ceramic spring 14 to buffer the force between the ceramic pad 15 and the ceramic spring 14.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, the surface of the ceramic pad 15 is adapted to fit and fit the inner wall of the interlayer 3 and can be rotatably connected. Both the surface of the ceramic pad 15 and the inner wall of the interlayer 3 are smoothly provided.

[0037] Specifically, under normal circumstances, the carbonization furnace body 2 inside the carbonization reaction device 1 needs to rotate in order to make the heat distribution more even. Therefore, the ceramic pad 15 and the ceramic spring 14 both need to rotate. With the adaptive and fitting rotation settings, and the smooth surface, the device can rotate more smoothly and is less prone to jamming, thus enhancing the performance of the carbonization reaction device 1.

[0038] In addition, both the ceramic spring 14 and the ceramic pad 15 are made of high-temperature resistant ceramic materials (such as alumina or silicon carbide ceramics). The ceramic spring 14 can absorb the thermal stress generated by temperature changes in the carbonization furnace body 2 through elastic deformation, avoiding the temperature gradient caused by local stress concentration. The smooth contact surface between the ceramic pad 15 and the inner wall of the interlayer 3 can reduce thermal resistance. At the same time, its low thermal conductivity can delay heat loss and promote the uniform axial diffusion of heat to the carbonization furnace body 2 through the first heat transfer ring 4, the second heat transfer ring 5 and the third heat transfer ring 6. Meanwhile, when the ceramic pad 15 rotates with the carbonization furnace body 2, the smooth surface reduces frictional heat generation, making the temperature field in the interlayer 3 more stable.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
