Description

Technical Field

[0001] This utility model relates to the field of biomass carbonization technology, and in particular to a biomass carbonization volatilization heat source incineration device. Background Technology

[0002] In the field of biomass carbonization, the efficient conduct of chemical reactions is inseparable from the assistance of catalysts. Adding a certain amount of catalyst to the internal materials during the carbonization reaction is a crucial step. Catalysts can excite and activate reactant molecules, prompting them to participate in the reaction with extremely high reactivity, thereby opening up chemical reaction pathways with low activation energy and greatly accelerating the chemical reaction process. This has an undeniable significance for improving the efficiency and quality of biomass carbonization.

[0003] Currently, under existing technologies, there are two main methods for adding catalysts. The first method is to pre-mix the catalyst with the materials. This method requires dedicated manpower, equipment, and time to pre-mix the catalyst and materials. This not only makes the entire production process cumbersome and complex, increasing equipment investment and operating costs, but also slows down the production pace, reduces production efficiency, and increases production costs to some extent.

[0004] Another common method involves adding catalyst to the material through a pre-installed inlet after it has been loaded into the reaction vessel. The reaction vessel then relies on its own mixing mechanism to ensure thorough mixing of the catalyst and material. However, this method has significant drawbacks. Due to the limited location of the inlet, material near the inlet will be the first to come into contact with and consume the catalyst, causing the reaction process in that area to be asynchronous with other areas. Furthermore, this method is highly dependent on the homogenization performance of the reaction vessel. If the mixing effect is poor, the carbonization degree of the final product is likely to be inconsistent, severely affecting the stability and consistency of product quality, increasing the defect rate, and causing significant production losses. Utility Model Content

[0005] The purpose of this invention is to provide a biomass carbonization and volatilization heat source incineration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution, which includes a carbonization furnace, a feeding valve at the bottom of the carbonization furnace, a gas pipeline at the top of the carbonization furnace connected to a purification device, an mounting block above one side of the carbonization furnace, an mounting plate on the other side of the carbonization furnace, a catalyst pumping assembly on the mounting plate, a through cylinder inside the carbonization furnace via several support legs, and a material turning assembly inside the carbonization furnace, the material turning assembly being located inside the through cylinder.

[0007] Furthermore, the material turning assembly includes a shaft tube, which is installed inside the carbonization furnace via a bearing seat. The shaft tube is also installed inside a cylindrical tube. Spiral blades are provided on the outer wall of the shaft tube, and several nozzles are also provided at equal intervals on the outer wall of the shaft tube. The nozzles are respectively located between the blades of the spiral blades. A sprocket is provided at the top of the shaft tube, and a motor is provided on the mounting block. A sprocket is provided on the drive end of the motor, and the sprocket is connected to the motor via a chain drive.

[0008] Furthermore, the catalyst pumping assembly includes a pump body mounted on a mounting plate, a storage tank on the side of the pump body, an input end of the pump body communicating with the storage tank via a second delivery pipe, an output end of the pump body being provided with a first delivery pipe, and the other end of the first delivery pipe being located inside the top of the shaft tube.

[0009] Furthermore, a pair of inverted L-shaped rods are provided on the wall of the shaft tube, and an array of stirring arms are provided on the inverted L-shaped rods. Each stirring arm is provided with an array of stirring claws, and the bottoms of the two inverted L-shaped rods are simultaneously provided on the slip ring.

[0010] Furthermore, a ring rail is provided on the outer wall of the tube, and the slip ring is slidably mounted on the ring rail.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] 1. This utility model eliminates the need for pre-mixing the catalyst and materials, thus eliminating the need for complex stirring and mixing operations before carbonization. Through the catalyst pumping component, the catalyst is added in real time during the reaction process of the materials entering the carbonization furnace, reducing the preliminary preparation process, lowering labor and time costs, improving overall production efficiency, and making the production process simpler and more efficient.

[0013] 2. Unlike the existing method of adding catalyst through the addition port after the material is loaded into the reaction vessel, this utility model has several nozzles evenly spaced on the outer wall of the shaft tube and located between the spiral blades. As the material moves upward through the spiral blades, the catalyst is evenly sprayed out from the nozzles. With the continuous tumbling of the material, the catalyst is evenly distributed in the material, avoiding the problem of uneven carbonization caused by the material near the addition port preferentially consuming the catalyst.

[0014] 3. This utility model uses the rotation of the shaft tube to drive the inverted L-shaped rod, which in turn causes the stirring arm and stirring claw to stir the material in all directions. On the one hand, this stirring allows the material to fully contact the catalyst, improving the efficiency of the catalyst. On the other hand, it further ensures that the material is heated evenly, comprehensively improving the carbonization effect, reducing the difference in the degree of carbonization of the product, and improving the product quality.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] like Figures 1-6 As shown, the present invention proposes a biomass carbonization volatilization heat source incineration device, which includes a carbonization furnace 1. A feeding valve 10 is installed at the bottom of the carbonization furnace 1 to facilitate the discharge of materials after carbonization. A gas pipeline 16 is provided at the top of the carbonization furnace 1. The gas pipeline 16 is connected to a purification device to transport the gas generated during the carbonization process to the purification device for treatment to meet environmental protection requirements. An installation block 11 is fixed on one side of the top of the carbonization furnace 1, and an installation plate 12 is provided on the other side. The installation plate 12 carries the catalyst pumping assembly 3 to provide the necessary catalyst conveying function for the carbonization process. Inside the carbonization furnace 1, a through cylinder 13 is stably supported by several support legs 14. A material turning assembly 2 is arranged inside the through cylinder 13 to be responsible for turning and transporting the material during the carbonization process.

[0024] The key component of the material turning assembly 2 is the shaft tube 20. The shaft tube 20 is securely installed in the carbonization furnace 1 through the bearing seat 21 and is located at the center of the tube 13. The outer wall of the shaft tube 20 is tightly fixed with a spiral blade 22. When the shaft tube 20 rotates, the spiral blade 22 can push the material to move up and down in the tube 13. At the same time, several nozzles 23 are evenly distributed on the outer wall of the shaft tube 20. These nozzles 23 are cleverly set in the space between the blades of the spiral blade 22 to ensure that the catalyst can be sprayed evenly onto the material. A sprocket 28 is installed on the top of the shaft tube 20. A motor 29 is fixed on the mounting block 11 on the top of the carbonization furnace 1. The drive end of the motor 29 is connected to a sprocket 210. The sprocket 28 and the sprocket 210 are connected by a chain 211. After the motor 29 starts, it drives the sprocket 210 to rotate, and then drives the sprocket 28 to rotate through the chain 211, thus realizing the rotation of the shaft tube 20.

[0025] The catalyst pumping assembly 3, mounted on the mounting plate 12, mainly consists of a pump body 30 and a storage tank 31. The side of the pump body 30 is connected to the storage tank 31. The input end of the pump body 30 is connected to the inside of the storage tank 31 through the second conveying pipe 33, which can extract the catalyst from the storage tank 31. The output end of the pump body 30 is connected to the first conveying pipe 32. The other end of the first conveying pipe 32 extends to the inside of the top of the shaft tube 20. When the pump body 30 is working, the catalyst is transported to the shaft tube 20 through the first conveying pipe 32 and sprayed out from the nozzle 23 on the outer wall of the shaft tube 20.

[0026] A pair of inverted L-shaped rods 24 are symmetrically installed on the wall of the shaft tube 20. Each inverted L-shaped rod 24 has an array of stirring arms 25, and each stirring arm 25 has an array of stirring claws 26. When the shaft tube 20 rotates, the inverted L-shaped rods 24 drive the stirring arms 25 and stirring claws 26 to stir the material, thereby enhancing the carbonization effect. In order to ensure the stability of the rotation of the inverted L-shaped rods 24, slip rings 27 are installed at the bottom of the two inverted L-shaped rods 24. Correspondingly, a ring rail 15 is provided on the outer wall of the tube 13. The slip rings 27 can slide smoothly on the ring rail 15, providing stable support and guidance for the rotation of the inverted L-shaped rods 24.

[0027] In actual operation, when using this equipment, the biomass materials are first fed into the carbonization furnace 1 in an orderly manner. Then, the motor 29 is started. After the motor 29 starts running, its power is transmitted to the second sprocket 210, driving the second sprocket 210 to rotate. The second sprocket 210 is linked with the first sprocket 28 through the chain 211, thereby driving the first sprocket 28 to rotate. Since the first sprocket 28 is connected to the shaft tube 20, it drives the shaft tube 20 to rotate synchronously. When the shaft tube 20 rotates, the material inside the carbonization furnace 1 begins a specific movement trajectory. In the tube 13, the material moves upward along the direction of the spiral blade 22 with the help of the spiral blade 22. This process achieves the key role of turning the bottom material upward, so that the material can be heated evenly in the carbonization furnace 1, providing good conditions for the subsequent carbonization reaction.

[0028] As the material moves continuously inside the cylinder 13, the pump 30 starts and extracts the catalyst from the storage tank 31. The catalyst is then transported to the shaft tube 20 through the conveying pipe 32. The catalyst in the shaft tube 20 is finally sprayed out from several nozzles 23 distributed at specific positions and evenly sprayed onto the material passing through the cylinder 13. The even spraying of the catalyst can effectively promote the carbonization reaction of the material and improve the carbonization efficiency and quality.

[0029] At the same time, during the rotation of the shaft tube 20, it also drives the two inverted L-shaped rods 24 to rotate synchronously. The stirring arms 25 and stirring claws 26 connected to the inverted L-shaped rods 24 move accordingly. With the coordinated cooperation of the stirring arms 25 and stirring claws 26, the material is stirred in all directions. This stirring not only allows the material to fully contact the catalyst, but also further ensures that the material is heated evenly, which greatly improves the carbonization effect and makes the carbonization process more efficient and stable.
