Technical Field

[0002] The air distribution system ensures the full mixing of fuel and air by reasonably controlling the amount and distribution of air sent into the furnace, promoting complete combustion. This helps improve combustion efficiency, reduce the generation of unburned carbon particles, and thus enhance energy utilization efficiency. Appropriate air volume distribution can help control the combustion temperature in the furnace, which is crucial for reducing harmful emissions such as nitrogen oxides. Some advanced air distribution systems can also achieve multi-stage air distribution to further optimize combustion conditions and reduce pollutant emissions. Biomass fuels are diverse, with large differences in their shapes, moisture contents, calorific values, etc. A good air distribution system can adjust the air volume according to different fuel characteristics to ensure stable combustion of various biomass fuels. The air distribution system also needs to consider the pressure balance inside and outside the furnace to avoid combustion instability caused by excessive negative pressure or safety risks brought by excessive positive pressure. Reasonable air distribution helps maintain a stable combustion environment.

Moreover, during use, the air distribution inside the furnace is uneven, affecting the stability of combustion. Therefore, a new air distribution structure for biomass boilers needs to be proposed.

[0023] In this embodiment, through the arranged processing box 1 and feed inlet 20, it is convenient to store and process the fuel. Then, under the action of the load-bearing plate 2, the water pump 3 and the water tank 4 can be connected to one side of the processing box 1. When using the water pump 3, the water in the water tank 4 is sprayed into the processing box 1 from the delivery pipe 9 and the sprinkler head 12. After use, the fuel in the processing box 1 can be extinguished to prevent unburned particulate matter from reigniting at the boiler tail, causing potential safety hazards. When the fuel in the processing box 1 is burned out, the generated smoke and dust will be discharged from the exhaust pipe 10 and the exhaust outlet 11 to prevent the deposition of smoke and dust from affecting the heat exchange efficiency in the boiler, resulting in increased energy consumption and decreased economic benefits. Then, under the action of the support frame 6, the load-bearing effect of the overall equipment can be improved, and the waste water generated after extinguishing the fuel can be discharged through the water outlet 18. A valve is arranged on one side of the water outlet 18, and the working state of the water outlet 18 can be controlled by using the valve.

[0024] Example 2: As Figures 1-4 shown, a filter plate 17 is fixedly connected to the inner wall of the processing box 1. A connecting plate 16 is fixedly connected to the top end of the filter plate 17. A rotating shaft 14 is rotatably connected to the middle of the top end of the connecting plate 16. A rotating motor 19 is connected to the top end of the rotating shaft 14. A connecting rod 15 is fixedly connected to the circumferential side of the rotating shaft 14. One end of the connecting rod 15 is fixedly connected to a stirring plate 13. An air supply box 5 is arranged on one side of the processing box 1. A cooling pipe 8 is connected to the top end of the air supply box 5. A micro pump 7 is arranged at the junction of the cooling pipe 8 and the air supply box 5. The cooling pipe 8 is arranged inside the processing box 1.

[0025] In this embodiment, the filter plate 17 provided can separate the fuel and the waste water generated after extinguishing the fuel. Then, under the action of the connecting plate 16, the rotating shaft 14 and the rotating motor 19 can be connected together. When the rotating motor 19 is used, it can drive the rotating shaft 14 to perform a rotating operation. Then, under the action of the connecting rod 15, the stirring plate 13 and the rotating shaft 14 can be connected together. After that, during the rotation of the rotating shaft 14, the stirring plate 13 can be synchronously driven to rotate, and air flow is generated to make the air distribution in the furnace more uniform, improving the combustion stability. Starting the micro pump 7 can control the operation of the air supply box 5. During the operation of the air supply box 5, the air speed inside the air supply box 5 can be transported into the processing box 1 through the cooling pipe 8.

[0026] The working principle of this embodiment: When in use, first, the fuel is put into the processing box 1 from the feed port 20. Then, starting the micro pump 7 can control the operation of the air supply box 5. During the operation of the air supply box 5, the air speed inside the air supply box 5 can be transported into the processing box 1 through the cooling pipe 8. When the rotating motor 19 is used, it can drive the rotating shaft 14 to perform a rotating operation. Then, under the action of the connecting rod 15, the stirring plate 13 and the rotating shaft 14 can be connected together. After that, during the rotation of the rotating shaft 14, the stirring plate 13 can be synchronously driven to rotate, and air flow is generated to make the air distribution in the furnace more uniform, improving the combustion stability. When the water pump 3 is used, the water in the water tank 4 is sprayed into the processing box 1 from the conveying pipe 9 and the nozzle 12. After use, the fuel inside the processing box 1 can be extinguished to prevent the unburned particulate matter from reigniting at the boiler tail, causing potential safety hazards. When the smoke generated after the fuel combustion in the processing box 1 is completed, it will be discharged from the exhaust pipe 10 and the exhaust port 11 to prevent the smoke deposition from affecting the heat exchange efficiency in the boiler, resulting in increased energy consumption and decreased economic benefits. The filter plate 17 can separate the fuel and the waste water generated after extinguishing the fuel. The water outlet 18 can be used to discharge the waste water generated after extinguishing the fuel. A valve is arranged on one side of the water outlet 18. By using the valve, the working state of the water outlet 18 can be controlled.
