Description

Technical Field

[0001] This utility model relates to the field of municipal solid waste incineration technology, specifically to a fire-fighting linkage device for the waste storage area of ​​a municipal solid waste incineration power plant. Background Technology

[0002] In municipal solid waste incineration power generation, the waste storage silo is a crucial component, serving as the key to waste storage. The volume and load of the silo vary considerably as it acts as a container for waste. However, because waste contains a large amount of organic matter, microbial decomposition during accumulation generates heat. If heat dissipation is not timely, spontaneous combustion can easily occur. Therefore, fire-fighting equipment must be installed inside the waste storage silo. However, current technologies mostly use sprinkler systems to extinguish fires within the silo. While traditional sprinkler systems cover a large area, they cannot promptly detect or effectively prevent localized overheating within the silo. Therefore, this project was developed to address these issues. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fire-fighting linkage device for the waste storage area of ​​a municipal solid waste incineration power plant, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting linkage device for a municipal solid waste incineration power plant's waste storage compartment, comprising an infrared imager mounted on a crossbeam of a grid frame at the top of the waste storage compartment. A fire water pipe is installed on the crossbeam, running parallel to a sprinkler system. A branch pipe is connected to the side of the fire water pipe, and an electrically controlled valve is installed on the branch pipe. One end of the branch pipe is connected to a booster pump. An equipment platform is mounted on the crossbeam, and a rotation control mechanism is mounted above the equipment platform. The output end of the rotation control mechanism extends below the equipment platform and is connected to a rotating platform. A support base is mounted on the rotating platform, and a spray nozzle is hinged to the support base. One end of the spray nozzle is connected to the outlet of the booster pump via a flexible connecting pipe, and a nozzle is installed at the other end of the spray nozzle. A swing control component is mounted on the rotating platform, and one end of the swing control component is connected to the spray nozzle.

[0005] The aforementioned rotation control mechanism includes a servo motor, a reducer, and an output shaft. The servo motor is mounted on the equipment platform, the input end of the reducer is connected to the drive end of the servo motor, and the output shaft is rotatably inserted into the equipment platform with its upper end connected to the output end of the reducer and its lower end connected to the rotating table.

[0006] The aforementioned swing control component includes a rotating seat, a hinged seat, and a hydraulic cylinder. The rotating seat is disposed on the lower end face of the rotating platform, the hinged seat is mounted on the side wall of the injection column, and the two ends of the hydraulic cylinder are respectively hinged to the hinged seat and the rotating seat.

[0007] A rotating support component is provided between the lower end face of the aforementioned equipment platform and the rotating table.

[0008] The aforementioned rotating support component includes an annular guide rail and an arc-shaped slider. The annular guide rail is fixed on the lower end face of the equipment platform and arranged coaxially with the output shaft.

[0010] This utility model provides a fire-fighting linkage device for the waste storage compartment of a municipal solid waste incineration power plant. It offers the following advantages: This fire-fighting linkage device utilizes an infrared imager mounted on the crossbeam of the grid structure at the top of the waste storage compartment to comprehensively monitor the temperature of the waste. When the local temperature inside the compartment rises to a set value, a rotation control mechanism is activated to rotate the rotating platform. Further, a swing control component is adjusted to regulate the spray direction of the spray nozzles, ensuring the nozzles are aligned with the heated area. Then, an electrically controlled valve on the water distribution pipe above that area is opened, and a booster pump is activated. The booster pump pressurizes the water, which is then injected into the spray nozzles through a flexible connecting pipe and sprayed out through the nozzles at the ends of the spray nozzles to cool and extinguish the fire. Furthermore, when the infrared imager detects an overall rise in the temperature of the waste inside the compartment, the sprinkler system can be activated simultaneously with localized spraying to provide comprehensive cooling. By supplementing the traditional sprinkler system with localized fire-fighting water spraying, a fire-fighting linkage is formed, significantly improving the reliability of fire-fighting operations within the waste storage compartment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Refer to the appendix of the instruction manual Figure 1-3As can be seen, this application specifically designs a fire-fighting linkage device for a municipal solid waste incineration power plant's waste storage compartment. It includes an infrared imager 2 mounted on a crossbeam 1 of the top grid frame of the waste storage compartment. A fire water pipe 3 is installed on the crossbeam 1, running parallel to a sprinkler pipe 21. A branch pipe 4 is connected to the side of the fire water pipe 3, and an electrically controlled valve 5 is installed on the branch pipe 4. One end of the branch pipe 4 is connected to a booster pump 6. An equipment platform 7 is mounted on the crossbeam 1, and a rotation control mechanism is installed above the equipment platform 7. The output end of the rotation control mechanism extends below the equipment platform 7 and is connected to a rotating platform 8. A support base 9 is mounted on the rotating platform 8, and a spray nozzle 10 is hinged to the support base 9. One end of the spray nozzle 10 is connected to the outlet end of the booster pump 6 via a flexible connecting pipe 11, and a nozzle 12 is installed at the other end of the spray nozzle 10. A swing control component is mounted on the rotating platform 8, and one end of the swing control component is connected to the spray nozzle 10. The device utilizes the grid frame 11 of the waste storage compartment to control the fire-fighting linkage device. The infrared imager 2 on the crossbeam 1 comprehensively monitors the temperature of the garbage inside the garbage bin. When the local temperature inside the garbage bin rises to a set value, the rotation control mechanism is activated to rotate and adjust the rotating platform 8, and further adjusts the swing control component to adjust the spray direction of the spray column 10. After the nozzle 12 of the spray column 10 is aligned with the heated area, the electric control valve 5 on the water distribution pipe 4 above the area is opened, and the booster pump 6 is started. The booster pump 6 pressurizes the water and injects it into the spray column 10 through the flexible connecting pipe 11, and then sprays it out through the nozzle 12 at the end of the spray column 10 to cool and extinguish the garbage. In addition, when the infrared imager 2 detects that the overall temperature of the garbage inside the garbage bin rises, the sprinkler pipe 21 can be opened at the same time as local spraying to spray and cool the garbage bin. Using local fire sprinkler as a supplement to the traditional sprinkler system forms a fire linkage, which can greatly improve the reliability of fire fighting operations inside the garbage bin.

[0017] In a preferred embodiment, the aforementioned rotation control mechanism includes a servo motor 13, a reducer 14, and an output shaft 15. The servo motor 13 is mounted on the equipment platform 7. The input end of the reducer 14 is connected to the drive end of the servo motor 13. The output shaft 15 is rotatably mounted on the equipment platform 7, with its upper end connected to the output end of the reducer 14 and its lower end connected to the rotating table 8. A rotation support component is provided between the lower end face of the equipment platform 7 and the rotating table 8. The rotation support component includes an annular guide rail 19 and an arc-shaped slider 20. The annular guide rail 19 is fixed on the lower end face of the equipment platform 7 and arranged coaxially with the output shaft 15. The arc-shaped slider 20 is slidably mounted on the annular guide rail 19 along the annular array and is fixedly connected to the upper end face of the rotating table 8. In use, the servo motor 13 and the reducer 14 are used to control the rotation of the output shaft 15 in a directional and angled manner, thereby adjusting the angle of the rotating table 8 and greatly increasing the working coverage area of ​​the spray column 10. The cooperation of the annular guide rail 19 and the arc-shaped slider 20 can further improve the rotational stability of the rotating table 8.

[0018] In specific implementation, as a preferred configuration, the aforementioned swing control component includes a rotating seat 16, a hinge seat 17, and a hydraulic cylinder 18.
