Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery devices, and in particular to a waste incineration waste heat recovery device. Background Technology

[0002] Waste incineration is a process that uses high-temperature oxidation reactions to burn waste. During this process, not only ash is generated, but also a large amount of heat energy is released. At the same time, the incineration process produces flue gas containing many components. This flue gas carries a lot of waste heat and is usually directly emitted into the atmosphere in a high-temperature form. If the heat energy contained in this high-temperature flue gas is left unused, it will undoubtedly cause a huge waste of energy. The core of flue gas waste heat recovery technology is to use various heat exchange devices, such as heat exchangers, heat pipes, and steam generators, to transfer the waste heat in the flue gas to media such as water and air, and then convert the waste heat into usable energy forms such as hot water, steam, or hot air.

[0003] A search revealed that Chinese patent number CN222417474U discloses a waste incineration waste heat recovery device, relating to the field of flue gas waste heat recovery technology. The device includes a heat-insulating tank, with a diversion box fixedly installed on one side of the heat-insulating tank. The diversion box is fixedly connected to an upper cover, and a water outlet tank is fixedly installed at the end of the diversion box connected to the upper cover. The water outlet tank is connected to an external heat energy utilization device. By using heating pipes and side diversion pipes, the contact range with the waste gas is increased, thereby allowing the heat in the waste gas to be fully utilized.

[0004] In the aforementioned device, the water storage tank is in a fixed position. This fixed position means that its relative position to the heat source is fixed, and it can only absorb heat through a limited contact area. For example, if the hot gas generated by waste incineration flows in a specific direction, the fixed water storage tank may only receive heat on one side, while the rest of the tank receives less heat, resulting in insufficient heat utilization and low overall thermal efficiency. Because the water storage tank is in a fixed position, different parts of it are at different distances from the heat source. The parts closer to the heat source receive more heat, while the parts farther away from the heat source receive less heat, which can easily cause uneven temperature distribution of the water inside the tank. Utility Model Content

[0005] The purpose of this utility model is to provide a waste incineration waste heat recovery device that can solve the problem of the fixed position of the water storage tank in the above-mentioned devices. The fixed position of the water storage tank means that its relative position with the heat source is fixed, and it can only absorb heat through a limited contact area. If the hot gas generated by waste incineration flows in a specific direction, the fixed water storage tank may only receive heat on one side, while the rest of the tank receives less heat, resulting in insufficient heat utilization and low overall thermal efficiency. Because the position of the water storage tank is fixed, the distance between different parts of it and the heat source is different. The parts closer to the heat source receive more heat, while the parts farther away from the heat source receive less heat, which can easily cause uneven temperature distribution of the water in the tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste incineration waste heat recovery device, including a housing and a recovery mechanism disposed on the outer side of the end of the housing, the recovery mechanism being used to efficiently utilize the heat energy generated by waste incineration.

[0007] In a preferred embodiment, the recycling mechanism includes a first motor mounted on the outer side of one end of the housing. A gear ring is fixedly connected to the inner side of one end of the housing. A connecting shaft is fixedly connected to the outer side of the main shaft of the first motor. A second gear is fixedly connected to the outer side of one end of the connecting shaft. A first rotating plate is rotatably connected to the inner side of one end of the housing. Multiple first gears are rotatably connected to the outer side of the end of the first rotating plate. The outer side of the second gear meshes with the outer side of the first gear. A second water storage pipe is fixedly connected to one side of the second gear. A first water storage pipe is fixedly connected to one side of the first gear. A top plate is detachably connected to the outer side of the top of the housing.

[0008] In a preferred embodiment, a gear ring is fixedly connected to the inner side of one end of the housing, and the outer side of the first gear meshes with the inner side of the gear ring.

[0009] In one preferred embodiment, a plurality of cups are placed on the upper surface of the top plate.

[0010] In a preferred embodiment, vertical grooves are fixedly connected to the outer sides of both ends of the housing, a second motor is installed on the outer side of the top of the vertical grooves, a threaded rod is fixedly connected to the outer side of the main shaft of the second motor, and the outer side of the threaded rod is threadedly connected to the inner sides of both ends of the top plate.

[0011] In a preferred embodiment, handles are fixedly connected to the outer ends of both ends of the box.

[0012] In a preferred embodiment, multiple casters are installed on the outer bottom end of the housing.

[0013] In a preferred embodiment, an air inlet slot and an air outlet slot are respectively provided on the outer side of the bottom end of the box.

[0014] Compared with existing technologies, the advantages and positive effects of this invention are as follows: In use, this invention allows the gas generated from waste incineration to flow through the outside of the first and second water storage pipes. The heat from the incineration gas heats the liquid inside the first and second water storage pipes, effectively recovering and utilizing the waste heat from waste incineration and improving energy efficiency. In the device, the second water storage pipe drives the connecting shaft and the second gear to rotate. The rotation of the second gear drives the rotation of the first gear, which meshes with the inner side of the gear ring, thereby driving the rotation of the first rotating plate.

Simultaneously, the second gear also drives the second water storage pipe to rotate. This series of rotational movements ensures continuous mixing of the liquid inside the first and second water storage pipes. This mixing action allows all parts of the liquid to fully contact the heat source during heating, avoiding localized overheating or undercooling and ensuring uniform heating of the liquid.

[0022] 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.

[0023] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a waste incineration waste heat recovery device, including a housing 1, and a recovery mechanism 2 disposed on the outer side of the end of the housing 1. The recovery mechanism 2 is used to efficiently utilize the heat energy generated by waste incineration. The recovery mechanism 2 includes a first motor 21, which is installed on the outer side of one end of the housing 1. A gear ring 28 is fixedly connected to the inner side of one end of the housing 1. A connecting shaft 24 is fixedly connected to the outer side of the main shaft of the first motor 21. A second gear 25 is fixedly connected to the outer side of one end of the connecting shaft 24. A first rotating plate 22 is rotatably connected to the inner side of one end of the body 1. Multiple first gears 23 are rotatably connected to the outer side of the end of the first rotating plate 22. The outer side of the second gear 25 meshes with the outer side of the first gear 23. A second water storage pipe 27 is fixedly connected to one side of the second gear 25. A first water storage pipe 26 is fixedly connected to one side of the first gear 23. A top plate 29 is detachably connected to the outer side of the top of the box body 1. A toothed ring 28 is fixedly connected to the inner side of one end of the box body 1. The outer side of the first gear 23 meshes with the inner side of the toothed ring 28.

[0024] When using the device, the user can inject the gas generated by waste incineration from one side of the housing 1. The incineration gas then flows over the outside of the first water storage pipe 26 and the second water storage pipe 27. The user can then activate the second water storage pipe 27, which drives the connecting shaft 24 and the second gear 25 to rotate. The rotation of the second gear 25 drives the first gear 23 to rotate, and the first gear 23 meshes with the inner side of the gear ring 28. Simultaneously, the rotation of the first gear 23 drives the first rotating plate 22 to rotate, which in turn drives the first water storage pipe 26 to rotate in a circular motion. The rotation of the first water storage pipe 26 itself, combined with the rotation of the second gear 25, drives the second water storage pipe 27 to rotate, thus continuously circulating the liquid inside the first and second water storage pipes 26 and 27. Mixing enhances heating efficiency. By allowing the gases generated from waste incineration to flow through the outside of the first water storage pipe 26 and the second water storage pipe 27, the heat from the incineration gases heats the liquid inside the first and second water storage pipes 26 and 27, effectively recovering and utilizing the waste heat from waste incineration and improving energy utilization. In the device, the second water storage pipe 27 drives the connecting shaft 24 and the second gear 25 to rotate. The rotation of the second gear 25 drives the first gear 23 to rotate. The first gear 23 meshes with the inner side of the gear ring 28, thereby driving the first rotating plate 22 to rotate. The first rotating plate 22, in turn, drives the first water storage pipe 26 to rotate in a circular motion and rotates itself. Simultaneously, the second gear 25 also drives the second water storage pipe 27 to rotate. This series of rotational movements ensures continuous mixing of the liquid inside the first and second water storage pipes 26 and 27. This mixing effect allows all parts of the liquid to fully contact the heat source during heating, avoiding localized overheating or undercooling and ensuring uniform heating of the liquid.

[0025] like Figure 1 - Figure 4 As shown, multiple cups 210 are placed on the upper surface of the top plate 29. Vertical grooves 212 are fixedly connected to the outer sides of both ends of the box 1. A second motor 214 is installed on the outer side of the top of the vertical groove 212. A threaded rod 213 is fixedly connected to the outer side of the main shaft of the second motor 214. The outer side of the threaded rod 213 is threadedly connected to the inner side of both ends of the top plate 29. Handles 211 are fixedly connected to the outer sides of both ends of the box 1. Multiple casters 215 are installed on the outer side of the bottom end of the box 1. An air inlet groove and an air outlet groove are respectively provided on the outer side of the bottom end of the box 1.

[0026] The user can start the second motor 214, which drives the threaded rod 213 to rotate. The rotation of the threaded rod 213 will cause the top plate 29 to rise vertically. At this time, the user can disassemble the first water storage pipe 26 and the second water storage pipe 27. At the same time, the gas inside the box 1 can also heat the top plate 29. The top plate 29 is made of a material with good thermal conductivity, so it can heat the cup 210 and the liquid inside the cup 210. The user can also move the device by pushing it with the handle 211. The casters 215 increase the flexibility of the device's movement.

[0027] Working principle: When using this device, the user can inject the gas generated by waste incineration from one side of the housing 1. At this time, the incineration gas flows through the outside of the first water storage pipe 26 and the second water storage pipe 27. The user can then activate the second water storage pipe 27, which drives the connecting shaft 24 and the second gear 25 to rotate. The rotation of the second gear 25 drives the first gear 23 to rotate. Simultaneously, the first gear 23 meshes with the inner side of the gear ring 28. The rotation of the first gear 23 drives the first rotating plate 22 to rotate, which in turn drives the first water storage pipe 26 to rotate in a circular motion. The first water storage pipe 26 itself rotates, and the second gear 25 drives the second water storage pipe 27 to rotate, thus holding the liquid inside the first water storage pipe 26 and the second water storage pipe 27. Continuous mixing increases heating efficiency. By allowing the gas generated from waste incineration to flow through the outside of the first water storage pipe 26 and the second water storage pipe 27, the heat of the incineration gas is used to heat the liquid inside the first water storage pipe 26 and the second water storage pipe 27, achieving effective recovery and utilization of waste heat from waste incineration and improving energy utilization. In the device, the second water storage pipe 27 drives the connecting shaft 24 and the second gear 25 to rotate. The rotation of the second gear 25 drives the first gear 23 to rotate. The first gear 23 meshes with the inner side of the gear ring 28, thereby driving the first rotating plate 22 to rotate. The first rotating plate 22 then drives the first water storage pipe 26 to perform a circular motion and rotates itself. At the same time, the second gear 25 also drives the second water storage pipe 27 to rotate. This series of rotational movements allows the liquid inside the first water storage pipe 26 and the second water storage pipe 27 to be continuously mixed. This mixing action allows all parts of the liquid to fully contact the heat source during the heating process, avoiding local overheating or undercooling and ensuring uniform heating of the liquid. The user can start the second motor 214, which drives the threaded rod 213 to rotate. The rotation of the threaded rod 213 will cause the top plate 29 to rise vertically. At this time, the user can disassemble the first water storage pipe 26 and the second water storage pipe 27. At the same time, the gas inside the box 1 can also heat the top plate 29. The top plate 29 is made of a material with good thermal conductivity, so it can heat the cup 210 and the liquid inside the cup 210. The user can also move the device by pushing it with the handle 211. The casters 215 increase the flexibility of the device's movement.
