Description

Technical Field

[0001] This invention relates to the field of carbonization furnace technology, and more specifically, to an internally heated vertical carbonization furnace. Background Technology

[0002] Internal heating vertical carbonization furnaces can convert biomass raw materials into coke materials. Coke materials are a high-quality solid fuel with advantages such as high calorific value, long burning time, and no smoke or odor. They can be used for home heating, barbecues, and industrial boiler fuel. In some remote areas, coke materials are an important source of energy for local residents.

[0003] Among the existing publicly available documents, patent publication number CN113403092A discloses a sealed rotary low-moisture quenching and coke discharge device. This technology involves assembling a sealed rotary low-moisture quenching and coke discharge device on the coke discharge bin of an internal combustion vertical carbonization furnace unit. The sealed rotary low-moisture quenching and coke discharge device is equipped with a nozzle for spraying quenching water and a valve core with a rotating function. When the valve core rotates, it can effectively spray quenching water onto the semi-quenched and agitated semi-coke, which is beneficial for the semi-coke to fully absorb moisture and reduce temperature, and also helps the semi-coke to absorb moisture evenly. This invention ensures the sealing performance of the system during the coke discharge process through sealed rotary coke discharge; the rotating valve core can evenly spray quenching water onto the semi-coke, effectively solving the problems of uneven quenching, false quenching due to heat, and uneven moisture content existing in the prior art. However, this patent has the following defects.

[0004] When processing coke raw materials in a vertical carbonization furnace, the raw materials need to be heated to a specified carbonization temperature. After carbonization, water is sprayed for wet quenching. This operation causes a significant drop in temperature inside the vertical carbonization furnace. When processing a new batch of raw materials, the heating waiting time is long and the heat energy consumption is high. At the same time, a large amount of coke raw materials tends to accumulate in the designated lower discharge area. This results in large internal heat loss and poor energy efficiency in the vertical carbonization furnace. Moreover, the discharge efficiency of large-area carbonization is low, and the waiting time for material discharge is long. The vertical carbonization furnace loses a lot of heat, resulting in low carbonization efficiency and poor energy efficiency. Summary of the Invention

[0012] Multiple connecting strips are fixedly connected to one end of multiple linkage columns, respectively;

[0013] A linkage ring is slidably installed on the outer wall of the vertical furnace shell. Multiple connecting strips are fixedly connected to the linkage ring. The linkage ring is used to move multiple connecting strips in linkage. A shrinking electric cylinder is installed between two of the connecting strips. The outer wall of the shrinking electric cylinder is fixedly connected to the vertical furnace shell. The shrinking end of the shrinking electric cylinder is fixedly connected to the lower surface of the linkage ring. The shrinking electric cylinder is electrically connected to the controller.

[0014] In a preferred embodiment, a synchronous positioning and cooling assembly is installed below the linkage bar, the synchronous positioning and cooling assembly comprising:

[0015] Multiple cover nozzles are located below the linkage bar. One end of each cover nozzle is fixedly connected to the vertical furnace shell. Each cover nozzle has a spray hole on its inner sidewall.

[0016] A ring pipe is installed at the other end of the cover nozzle. Multiple cover nozzles are fixedly connected to the ring pipe. A booster pump is installed on the outer wall of the ring pipe, and the booster pump is electrically connected to the controller.

[0017] In a preferred embodiment, a plurality of the cover nozzles are arranged in a circumferentially equidistant distribution, and the inner walls of the cover nozzles and the annular pipes are both smooth surfaces.

[0018] In a preferred embodiment, a resistance heater is installed inside the vertical furnace shell to heat the interior of the vertical furnace shell, and the bottom ends of the plurality of bottom support plates are fixedly connected to the resistance heater.

[0019] A distance sensor is fixedly installed at the top of one of the linkage bars, and both the resistance heater and the distance sensor are electrically connected to the controller.

[0020] In a preferred embodiment, two reinforcing columns are fixedly connected to the bottom of the vertical furnace shell, and a loading hopper is installed at the bottom of the reinforcing columns. Both reinforcing columns are fixedly connected to the loading hopper, and two support plates are fixedly connected to the outer wall of the loading hopper. The controller is fixed to the outer wall of one of the support plates.

[0021] In a preferred embodiment, the inner wall of the loading hopper is a smooth surface, and the two support plates are symmetrically arranged about the loading hopper.

[0022] In a preferred embodiment, a plurality of threaded covers are installed at the top of the vertical furnace shell and near its edge, and the plurality of covers are arranged in a circumferentially equidistant distribution.

[0023] In a preferred embodiment, an exhaust pipe is fixedly connected to the top of the vertical furnace shell and near its center point, and the exhaust pipe is connected to the vertical furnace shell.

[0024] The technical effects and advantages of this invention are as follows:

[0025] This invention employs a synchronous linkage carbonization component. The sealing block causes the outer sealing frame to separate from the vertical furnace shell, simultaneously moving the carbonization loading frame to the right. The carbonization loading frame then moves the inner sealing frame to the right to seal, while the solid left side of the carbonization loading frame and the inner sealing frame continue to provide thermal insulation. At this point, the bottom opening of the carbonization loading frame moves to the outside of the vertical furnace shell, while the bottom support plate remains stationary and no longer obstructs the bottom opening of the carbonization loading frame. This allows coke raw materials in multiple carbonization loading frames to be discharged simultaneously from the bottom opening, achieving large-area, multi-point synchronous discharge. During discharge, the solid left side of the carbonization loading frame and the inner sealing frame continue to provide thermal insulation for the vertical furnace shell, while preventing water from being released inside the furnace shell. This significantly shortens the waiting time for material feeding, greatly reduces heat loss inside the furnace shell, and improves carbonization efficiency and energy saving.

[0026] This invention employs a linkage moving component. The shrinking end of the electric cylinder drives the linkage ring to slide down along the outer wall of the vertical furnace shell. The linkage ring drives multiple connecting strips to move downward, causing the linkage column to slide and squeeze against the guide groove, thus moving the sealing block to the right. Multiple sealing blocks move out of the vertical furnace shell simultaneously. This synchronous linkage moving method is more efficient, making the discharge process of multiple carbonization loading frames more efficient, and effectively avoiding excessive heat loss inside the vertical furnace shell, thereby improving carbonization efficiency and energy saving effect.

[0027] This invention employs a synchronous positioning cooling component. When the carbonized coke raw materials in multiple carbonization loading frames are discharged, a booster pump pressurizes tap water and injects it into multiple covered spray pipes through a ring pipe. The water mist is sprayed through the spray holes in a U-shaped path to cool and wet-quench the coke raw materials during the feeding process. This multi-point water treatment outside the vertical furnace shell avoids heat loss caused by water inside the furnace shell, ensuring a higher temperature inside the furnace shell. This allows for direct high-temperature carbonization of the next batch of coke raw materials, significantly shortening the heating time. This not only improves the carbonization cooling efficiency but also ensures the continuous and efficient operation of the carbonization furnace, resulting in significant energy savings.

[0028] In summary, through the interaction of the aforementioned multiple functions, firstly, multiple sealing blocks are simultaneously moved out of the vertical furnace shell, and secondly, coke raw materials in multiple carbonization loading frames can be simultaneously discharged from the bottom openings. Simultaneously, the solid surface on the left side of the carbonization loading frame and the inner sealing frame continue to be insulated and sealed. At the same time, a U-shaped water mist is sprayed through nozzles to cool and wet-quench the coke raw materials during feeding. In summary, this achieves simultaneous discharge over a large area and at multiple points, while simultaneously implementing insulated sealing operations at the connection points between each carbonization loading frame and the sealing blocks. Furthermore, it performs large-area, multi-point cooling and wet-quenching treatment during feeding, significantly shortening the waiting time for feeding and the cooling and wet-quenching treatment, greatly reducing heat loss from the vertical furnace shell, and improving carbonization efficiency and energy saving.

[0038] 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.

[0039] As attached Figure 1 - Appendix Figure 8 The diagram shows an internally heated vertical carbonization furnace. This furnace is equipped with a synchronous linkage carbonization component, a linkage moving component, and a synchronous positioning cooling component. The synchronous linkage carbonization component, linkage moving component, and synchronous positioning cooling component enable simultaneous discharge of material at multiple points over a large area, while simultaneously achieving heat insulation and sealing operations at the connection points between each carbonization loading frame 4 and the sealing block 2. Furthermore, it enables large-area, multi-point cooling and wet quenching treatment during material discharge, significantly shortening the waiting time for material discharge and the wet quenching treatment, greatly reducing the heat loss inside the furnace shell 1, and improving carbonization efficiency and energy saving. The specific structural configuration of the synchronous linkage carbonization component, linkage moving component, and synchronous positioning cooling component is as follows.

[0040] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 6As shown, a synchronous carbonization assembly is installed inside the vertical furnace shell 1. The synchronous carbonization assembly includes: multiple sealing blocks 2, each of which is slidably connected inside the vertical furnace shell 1, and an outer sealing frame 3 is fixedly connected to the outer wall of each sealing block 2, with the outer sealing frame 3 in contact with the vertical furnace shell 1; a carbonization support frame 4, fixed to one side of the sealing blocks 2, with multiple through holes 27 on both sides of the inner wall of the carbonization support frame 4, and an inner sealing frame 5 fixedly connected to the outer wall of the carbonization support frame 4; a bottom support plate 6, slidably connected to the inner wall of the carbonization support frame 4 near its bottom end, with a support column 7 fixedly connected to one side of the bottom support plate 6, and the sealing blocks 2 are slidably connected to the support column 7. A linkage strip 8 is fixedly connected to one end of the support column 7, and the linkage strip 8 is fixedly connected to the vertical furnace shell 1. A linkage moving assembly is provided inside the sealing blocks 2, which is used to move multiple sealing blocks 2 in a linkage manner. Multiple sealing blocks 2 are arranged in a circular, equidistant pattern. The outer walls of the carbonization support frame 4 and the sealing blocks 2 are smooth surfaces, so that the sealing blocks 2 can move the outer sealing frame 3 to the right. The carbonization support frame 4 moves to the right along the bottom support plate 6, and the sealing blocks 2 also begin to slide to the right along the outer wall of the support column 7. The inner sealing frame 5 is inside the vertical furnace shell 1 and begins to seal the carbonization support frame 4 and the edge of the vertical furnace shell 1. The bottom support plate 6 no longer blocks the bottom opening of the carbonization support frame 4, and the carbonized coke raw materials inside the multiple carbonization support frames 4 are quickly discharged synchronously, while avoiding a large amount of heat loss inside the vertical furnace shell 1.

[0041] In this embodiment, as shown in the appendix Figure 5 - Appendix Figure 6 As shown, the linkage moving assembly includes: multiple linkage columns 9, each corresponding to and slidably connected to the inner wall of multiple sealing blocks 2; each sealing block 2 has a limit ring 10 slidably connected to both sides; both limit rings 10 are fixedly connected to the linkage columns 9; a guide groove 14 is provided on one side of the inner wall of the sealing block 2, and the guide groove 14 is slidably connected to the linkage column 9; multiple connecting strips 11, each corresponding to and fixedly connected to one end of the multiple linkage columns 9; and a linkage ring 12, slidably installed on the outer wall of the vertical furnace shell 1; the multiple connecting strips 11 are fixedly connected to the linkage ring 12, and the linkage ring 12 is used to linkage move the multiple connecting strips 11, wherein two connecting strips 11... A shrinking electric cylinder 13 is installed in the middle. The outer wall of the shrinking electric cylinder 13 is fixedly connected to the vertical furnace shell 1. The shrinking end of the shrinking electric cylinder 13 is fixedly connected to the lower surface of the linkage ring 12. The shrinking electric cylinder 13 is electrically connected to the controller 24 so that when the coke raw material is carbonized, the shrinking end of the shrinking electric cylinder 13 starts to drive the linkage ring 12 to move down. The linkage ring 12 simultaneously drives multiple connecting strips 11 to move down. The linkage column 9 drives two limit rings 10 to move down. The linkage column 9 slides and squeezes with the guide inclined groove 14, so that the sealing block 2 starts to move to the right. In this way, multiple sealing blocks 2 move out of the vertical furnace shell 1 in a synchronous linkage, so that multiple sealing blocks 2 form a multi-point synchronous linkage and rapid movement.

[0042] In this embodiment, as shown in the appendix Figure 7 As shown, a synchronous positioning and cooling assembly is installed below the linkage bar 8. The synchronous positioning and cooling assembly includes: multiple covering nozzles 15, all located below the linkage bar 8, one end of each covering nozzle 15 being fixedly connected to the vertical furnace shell 1, and each covering nozzle 15 having a spray hole 16 on its inner sidewall; and a ring pipe 17, installed at the other end of the covering nozzles 15, with each covering nozzle 15 being fixedly connected to the ring pipe 17. A booster pump 18 is installed on the outer wall of the ring pipe 17, and the booster pump 18 is electrically connected to the controller 24. Multiple covering nozzles 15 are arranged in a circumferentially equidistant pattern. The inner walls of the covering nozzles 15 and the ring pipe 17 are smooth surfaces. This allows the booster pump 18 to pressurize tap water and introduce it into the ring pipe 17 when the carbonized coke raw material inside the multiple carbonization loading frames 4 is discharged. The water mist is sprayed through the nozzle holes 16 on the inner side wall of each covering nozzle 15 in a U-shaped path. The water mist performs multi-point covering cooling and wet quenching treatment on the carbonized coke raw material while it is being discharged. The coke raw material after wet quenching is discharged out along the inside of the loading hopper 22, avoiding the problem of a sudden temperature drop caused by water inside the vertical furnace shell 1 and saving the heat energy inside the vertical furnace shell 1.

[0043] In this embodiment, as shown in the appendix Figure 4 As shown, a resistance heater 19 is installed inside the vertical furnace shell 1. The resistance heater 19 is used to heat the inside of the vertical furnace shell 1. The bottom ends of multiple bottom support plates 6 are fixedly connected to the resistance heater 19 so that the controller 24 can turn on the resistance heater 19. The resistance heater 19 heats the inside of the vertical furnace shell 1 internally. At the same time, the resistance heater 19 can also provide reinforcement support for multiple bottom support plates 6, increasing the stability of the bottom support plates 6. A distance sensor 20 is fixedly installed at the top of one of the linkage bars 8. The resistance heater 19 and the distance sensor 20 are both electrically connected to the controller 24 so that the distance value between the sealing block 2 and the distance sensor 20 can be sensed by the distance sensor 20. When the sensed distance value is the same as the distance value set by the controller 24, the controller 24 closes the shrinking electric cylinder 13. In this way, the distance position of the linkage movement of multiple sealing blocks 2 is precisely controlled.

[0044] In this embodiment, as shown in the appendix Figure 7As shown, two reinforcing columns 21 are fixedly connected to the bottom of the vertical furnace shell 1. A loading hopper 22 is installed at the bottom of the reinforcing columns 21. Both reinforcing columns 21 are fixedly connected to the loading hopper 22. Two support plates 23 are fixedly connected to the outer wall of the loading hopper 22. The controller 24 is fixed to the outer wall of one of the support plates 23. The inner wall of the loading hopper 22 is smooth. The two support plates 23 are symmetrically arranged about the loading hopper 22. The support plates 23 are fixed by bolts inserted into the mounting holes of the support plates 23. The loading hopper 22 supports the reinforcing columns 21, the reinforcing columns 21 support the vertical furnace shell 1, and the support plates 23 can also provide support for the controller 24, increasing the stability of the controller 24.

[0045] In this embodiment, as shown in the appendix Figure 8 As shown, multiple threaded covers 25 are installed at the top of the vertical furnace shell 1 and near its edge. The multiple covers 25 are arranged in a circumferentially equidistant pattern. By reversing the multiple covers 25, the multiple covers 25 are separated from the feed inlet at the top of the vertical furnace shell 1, and the coke raw materials are placed into the multiple carbonization loading frames 4, which facilitates feeding into the multiple carbonization loading frames 4 and realizes carbonization processing.

[0046] In this embodiment, as shown in the appendix Figure 8 As shown, an exhaust pipe 26 is fixedly connected to the top of the vertical furnace shell 1 and near its center point. The exhaust pipe 26 is connected to the vertical furnace shell 1 so that the gas from the carbonization process inside the vertical furnace shell 1 can be discharged through the exhaust pipe 26, thereby realizing the guided exhaust operation inside the vertical furnace shell 1.

[0047] The working principle of the internally heated vertical carbonization furnace of this invention is as follows:

[0048] First, during the carbonization process, the support plate 23 is fixed by inserting bolts into the mounting holes. The support plate 23 supports the loading hopper 22, which in turn supports the reinforcing column 21, which in turn supports the vertical furnace shell 1, increasing the stability of the furnace shell 1. A water pipe is threadedly connected to the input end of the booster pump 18 to establish a connection. Then, multiple covers 25 are reversed, separating them from the feed inlet at the top of the furnace shell 1. This allows coke raw materials to be placed into multiple carbonization loading frames 4. Simultaneously, the bottom support plate 6 inside the carbonization loading frame 4 provides support to the bottom of the coke raw materials. Finally, the multiple covers 25 are rotated forward, closing the furnace shell 1. At this time, the sealing block 2 supports the outer sealing frame 3, and the outer sealing frame 3 seals the edge gap at the connection between the sealing block 2 and the vertical furnace shell 1. In this way, the controller 24 is powered on to turn on the resistance heater 19, and the resistance heater 19 heats the inside of the vertical furnace shell 1 internally. The hot air can heat and carbonize the coke raw material through the through hole 27, thereby carbonizing the coke raw material inside the carbonization support frame 4. The carbonization gas is discharged through the exhaust pipe 26.

[0049] Secondly, when the present invention performs linkage movement, after the coke raw material is carbonized, the controller 24 starts the shrinking electric cylinder 13. The shrinking end of the shrinking electric cylinder 13 drives the linkage ring 12 to move down. The linkage ring 12 slides down along the outer wall of the vertical furnace shell 1. At the same time, the linkage ring 12 drives multiple connecting strips 11 to move down. The connecting strips 11 drive the linkage column 9 to move down and squeeze. The linkage column 9 drives two limiting rings 10 to move down. The two limiting rings 10 and the linkage column 9 slide on the sealing block 2. In this way, the linkage column 9 slides and squeezes with the guide inclined groove 14. Under the action of the inclined surface of the guide inclined groove 14, the linkage column 9 causes the sealing block 2 to move to the right, so that multiple sealing blocks 2 can move out of the interior of the vertical furnace shell 1.

[0050] Meanwhile, during the synchronous carbonization process of this invention, please refer to the appendix for the "left side" and "right shift" orientations. Figure 3 In the orientation of the furnace shell 1, the sealing block 2 moves the outer sealing frame 3 to the right, and the outer sealing frame 3 begins to separate from the furnace shell 1. The sealing block 2 moves the carbonization support frame 4 to the right, and the carbonization support frame 4 moves to the right along the bottom support plate 6. The furnace shell 1 supports the linkage bar 8, and the linkage bar 8 supports the support column 7. The sealing block 2 slides to the right along the outer wall of the support column 7, and the carbonization support frame 4 moves to the right along the outer wall of the support column 7. The distance between the sealing block 2 and the distance sensor 20 is sensed. When the sensed distance value is the same as the distance value set by the controller 24, the controller 24 closes the shrinking electric cylinder 13.

[0051] Simultaneously, the carbonization support frame 4 moves the inner sealing frame 5 to the right until the inner sealing frame 5 is pressed against the inner wall of the sealing block 2. The inner sealing frame 5 seals the carbonization support frame 4 at the edge of the vertical furnace shell 1, preventing heat loss from the interior of the vertical furnace shell 1. Meanwhile, the left side of the carbonization support frame 4 is a solid, closed surface, while the multiple through holes 27 on the carbonization support frame 4 can move to the outside of the vertical furnace shell 1. Thus, the solid left side of the carbonization support frame 4 and the inner sealing frame 5 continue to provide thermal insulation and sealing for the interior of the vertical furnace shell 1. This ensures that the bottom of the carbonization support frame 4... The opening is moved to the outside of the vertical furnace shell 1, and at the same time, the resistance heater 19 supports the bottom support plate 6, keeping the bottom support plate 6 stationary. In this way, the bottom support plate 6 no longer blocks the bottom opening of the carbonization loading frame 4, so that the carbonized coke raw materials inside multiple carbonization loading frames 4 begin to be discharged synchronously from the bottom opening. This achieves multi-point, large-area synchronous discharge of material outside the vertical furnace shell 1, which can discharge a large area of ​​carbonized coke raw materials synchronously from multiple points, while avoiding excessive heat loss inside the vertical furnace shell 1 during discharge.

[0052] Simultaneously, during synchronous positioning cooling, when the carbonized coke raw materials inside the multiple carbonization loading frames 4 are discharged, the booster pump 18 is immediately started by the controller 24. The booster pump 18 pressurizes tap water and enters the ring pipe 17, which then flows into multiple covering nozzles 15. The spray nozzles 16 inside the covering nozzles 15 form a U-shaped water mist spray. In this way, the water mist sprays onto the carbonized coke raw materials while they are being discharged, achieving a wet quenching treatment. After wet quenching, the coke raw materials are discharged through the loading hopper 22. In this way, water at multiple points outside the vertical furnace shell 1 cools and quenches a large amount of carbonized coke raw materials, preventing heat loss inside the vertical furnace shell 1 and ensuring a high temperature inside the vertical furnace shell 1 for the next batch of coke raw materials to continue high-temperature carbonization treatment.
