Description

Technical Field

[0001] This application relates to the field of biomass carbonization furnace technology, and in particular to a cooling device in a biomass carbonization furnace. Background Technology

[0002] The grate in a biomass carbonization furnace is the core component supporting material combustion and ventilation. Traditional grates mostly adopt a fixed metal grid structure. After assembly, necessary ventilation gaps are maintained between the plates so that air can enter the fuel layer for combustion. The ash after combustion is discharged manually or mechanically. However, being in a high-temperature environment for a long time, grates are prone to problems such as thermal stress concentration and structural deformation. They are also prone to material fatigue or ablation due to local overheating.

[0003] Therefore, those skilled in the art have provided a cooling device for a biomass carbonization furnace to solve the problems mentioned in the background art. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a cooling device for a biomass carbonization furnace.

[0005] The cooling device in a biomass carbonization furnace provided in this application adopts the following technical solution:

[0006] A cooling device for a biomass carbonization furnace includes two water distribution pipes, with water supply pipes installed at the ends of the water distribution pipes. Several pipe bodies are installed between the two water distribution pipes, and heat dissipation components are provided on the inner side of the pipe bodies. Installation nozzles are threaded to both ends of the pipe bodies, and second connecting pipes are fixedly connected to the ends of the installation nozzles. Several first connecting pipes are symmetrically installed at the near ends of the two water distribution pipes, and connecting sleeves are threaded between the first connecting pipes and the second connecting pipes.

[0007] Preferably, the heat dissipation assembly includes three heat dissipation fins fixed at their ends, with an included angle of 120° between two adjacent heat dissipation fins. An arc-shaped piece is fixed at the end of each heat dissipation fin, and an installation strip is fixed at the outer side of the arc-shaped piece. An installation groove is provided on the inner side of the tube body, and the installation strip is installed in the installation groove.

[0008] Preferably, the heat dissipation fins have several through holes.

[0009] Preferably, a sleeve is fitted on the outer side of the tube body, and the sleeve has a prismatic design.

[0010] Preferably, the side wall of the tube body has a vertical surface, which limits the sleeve installed on the outside.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. The 120° symmetrical distribution and through-hole design of the heat dissipation fins create turbulence and uniformly distribute the cooling water, significantly improving the heat exchange efficiency of the inner wall of the tube. The symmetrical distribution structure of the water distribution pipes ensures uniform water flow within each tube, preventing grate thermal deformation caused by localized overheating. The prismatic sleeve is rigidly connected to the tube body through a vertical surface, utilizing the bending resistance of the polygonal cross-section to suppress deformation under high-temperature conditions. The heat dissipation fins fit seamlessly with the inner wall of the tube through arc-shaped plates, and the combination of the mounting strip and mounting groove ensures efficient heat transfer. The threaded connection design of the mounting nozzle and connecting sleeve supports quick disassembly and replacement of individual tubes. The heat dissipation fins can be directly pulled out along the mounting groove to expose the inner wall of the tube, facilitating high-pressure water jet cleaning or chemical descaling to solve the problem of scale accumulation. It has the effect of cooling the grate, preventing overheating that could lead to material fatigue or ablation, and facilitates grate disassembly, replacement, and descaling.

[0018] Example 1

[0019] like Figure 1-3As shown, this application discloses a cooling device in a biomass carbonization furnace, including two water distribution pipes 1, a water supply pipe 2 installed at the end of the water distribution pipe 1, a plurality of pipe bodies 7 installed between the two water distribution pipes 1, a heat dissipation component provided on the inner side of the pipe body 7, an installation nozzle 6 installed at both ends of the pipe body 7, a second connecting pipe 5 installed at the end of the installation nozzle 6, a plurality of first connecting pipes 3 symmetrically installed at the near ends of the two water distribution pipes 1, and a connecting sleeve 4 installed between the first connecting pipes 3 and the second connecting pipes 5;

[0020] Water is introduced into the water distribution pipe 1 at one end through the water supply pipe 2. The water enters the pipe body 7 and cools the pipe body 7. The heat dissipation effect is improved by the heat dissipation component inside the pipe body 7. The water enters the water distribution pipe 1 at the other end through the water supply pipe 2 at the other end.

[0021] like Figure 2-3 As shown, the heat dissipation assembly includes three heat dissipation fins 11 fixed at their ends. The included angle between two adjacent heat dissipation fins 11 is 120°. An arc-shaped plate 13 is installed at the end of the heat dissipation fin 11. An installation strip 14 is installed on the outer side of the arc-shaped plate 13. An installation groove 10 is opened on the inner side of the tube body 7. The installation strip 14 is installed in the installation groove 10. The heat dissipation fins 11 contact the inner wall of the tube body 7 through the arc-shaped plate 13, which can increase the contact area with the tube body 7. The heat dissipation fins 11 and the through hole 12 are installed by inserting the installation strip 14 into the installation groove 10.

[0022] like Figure 2 As shown, the heat dissipation fins 11 have several through holes 12, which can guide the flow and make the liquid evenly distributed in the tube 7.

[0023] like Figure 1 As shown, a sleeve 9 is fitted on the outside of the tube body 7. The sleeve 9 has a prismatic design. By installing the sleeve 9 on the outside of the vertical surface 8, the vertical surface 8 can be protected, and the prismatic shape can improve the structural strength.

[0024] like Figure 2-3 As shown, the side wall of the tube body 7 has a vertical surface 8, which limits the sleeve 9 installed on the outside.

[0025] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] The implementation principle of a cooling device in a biomass carbonization furnace according to an embodiment of this application is as follows:

[0028] In use, cooling water enters the distribution pipe 1 through the water supply pipe 2, and is then distributed to each pipe body 7 via the first connecting pipe 3. Inside the pipe body 7, the water flow is guided by the heat dissipation fins 11, forming turbulence through the through holes 12, and ensuring uniform distribution of the cooling water to improve cooling efficiency. The cooled water then enters another distribution pipe 1 through the second connecting pipe 5, and is finally discharged through another water supply pipe 2. The absorbed high-temperature heat is transferred through the outer wall of the pipe body 7 to the internal heat dissipation fins 11, where the cooling water carries away the heat. The heat dissipation fins 11, through the arc-shaped plates 13 and... The inner wall of the tube fits tightly, improving heat conduction efficiency. The prismatic sleeve 9 is rigidly connected to the tube body 7 through the vertical surface 8, suppressing high-temperature deformation. Loosening the connecting sleeve 4 can separate the tube body 7 from the water distribution pipe 1, allowing the damaged tube body to be directly pulled out. The heat dissipation fins 11 slide out along the mounting groove 10 through the mounting strip 14. The separable design of the heat dissipation fins 11 and the tube body 7 completely exposes the inner wall of the tube body, supporting high-pressure water gun washing or chemical descaling agent soaking. The threaded connection design of the mounting nozzle 6 ensures the precise positioning of the new tube body 7, restoring the system's sealing performance.
