Description

Technical Field

[0001] This utility model relates to the field of recycling device technology, specifically a heat energy recovery device for diethylene glycol production. Background Technology

[0002] Recycling facilities are devices or systems used to collect, process, and reuse waste. They are widely used in various fields, from waste recycling in industrial production to waste sorting in household life. Recycling facilities typically include collection containers, sorting equipment, crushing or compaction machinery, and possibly chemical or thermal treatment facilities. These facilities are designed to reduce resource waste, reduce environmental pollution, and promote sustainable development and the circular economy. By converting waste into reusable materials or energy, recycling facilities play a vital role in protecting the Earth's resources and improving the human living environment.

[0003] A heat recovery unit for diethylene glycol production is a specialized waste heat recovery device used in the diethylene glycol production process. This unit efficiently recovers heat energy from high-temperature flue gas, steam, or hot water generated during production, converting it into usable heat or electricity. This improves energy efficiency and reduces production costs. The unit typically includes key equipment such as heat exchangers, waste heat boilers, and steam turbines. It can be customized to the specific characteristics of diethylene glycol production processes to maximize waste heat recovery and utilization, reducing energy waste and environmental pollution. By adopting this heat recovery unit, diethylene glycol producers can achieve energy conservation, emission reduction, and green production goals, contributing to sustainable development.

[0004] However, existing heat recovery devices for diethylene glycol production, especially those with traditional fixed connections, result in significant heat loss during production, leading to energy waste. Furthermore, they require additional energy input to maintain the production temperature, increasing energy consumption. Additionally, it is difficult to adjust heat exchange efficiency according to different production needs and environmental conditions, limiting the flexibility and adaptability of the process. Moreover, the heat-conducting plates can shift due to vibration or other external factors, causing unstable heat exchange efficiency. To address these issues, a heat recovery device for diethylene glycol production is proposed. Utility Model Content

[0031] 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.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figures 1-3This utility model discloses a heat recovery device for diethylene glycol production, comprising a support plate 1, through which the required materials can be discharged via a discharge pipe at the bottom of the support plate 1, and a first heat-insulating barrel 3 fixedly connected to the top of the support plate 1. The first heat-insulating barrel 3 can hold the required materials for contact reaction, and the required materials can be fed into the first heat-insulating barrel 3 through a feed pipe. A second heat-insulating barrel 4 is slidably connected to one end of a heat-conducting plate 5, and the second heat-insulating barrel 4 is fixedly connected to the support plate 1. The second heat-insulating barrel 4 can hold and fix the required components and structures. A cover 9 is fixedly connected to the outer wall of a turntable 8, and the cover 9 is in contact with both the first heat-insulating barrel 3 and the second heat-insulating barrel 4. The cover 9 can connect and limit the required components and structures. A servo motor 10 is fixedly connected to one end of the outer wall of the cover 9, and the servo motor 10 can make the transmission rod 11 rotate inside the cover 9.

[0034] Reference Figures 2-4 The outer wall of the first insulation container 3 is slidably connected with uniformly distributed heat-conducting plates 5. An insulating pad 6 is fixedly connected to one end of each heat-conducting plate 5. The heat-conducting plates 5 transfer the temperature of the liquid inside the first insulation container 3 to the second insulation container 4, and the insulating pad 6 isolates the heat. A slider 7 is slidably connected to the top of each heat-conducting plate 5. A turntable 8 is slidably connected to the top of each slider 7. The output end of the servo motor 10 passes through the cover 9 and is fixedly connected to a transmission rod 11, which is rotatably connected to the cover 9. A worm gear 12 is fixedly connected to one end of the transmission rod 11. A transmission assembly is provided on the top of the turntable 8. Disassembly assemblies are provided at both ends of the outer wall of the cover 9. The transmission assembly includes a rotating rod 13, which is connected to a rotating... The top of the disc 8 is rotatably connected through it. The top of the rotating rod 13 is fixedly connected to a worm gear 14, which meshes with the worm 12. The bottom of the rotating rod 13 is fixedly connected to a disc 15, which is rotatably connected to the cover 9. The disc 15 is slidably connected to the slider 7. The bottom of the inner wall of the cover 9 is fixedly connected to evenly distributed baffles 16, which are slidably connected to the slider 7. By rotating the transmission rod 11, the worm 12 drives the worm gear 14 to rotate inside the cover 9, thereby driving the slider 7 to slide on the turntable 8. This allows the slider 7 to slide between the baffles 16, thus flexibly adjusting the heat exchange efficiency according to different production needs and environmental conditions to adapt to different process requirements.

[0035] Reference Figure 1 and Figure 4The disassembly assembly includes a fixing block 17, which is fixedly connected to both ends of the outer wall of the cover 9. Connecting blocks 18 are fixedly connected to both ends of the outer wall of the second insulation barrel 4. Fixing rods 19 are fixedly connected to both sides of the top of the connecting blocks 18, and the fixing rods 19 and connecting blocks 18 pass through and slide together. Springs 20 are installed inside each fixing rod 19, and a limiting rod 21 is fixedly connected to the other end of each spring 20. The limiting rod 21 is slidably connected to the fixing rod 19 and passes through and slides through the fixing block 17. By allowing the limiting rod 21 to slide into the fixing rod 19, the spring 20 is compressed, causing the fixing rod 19 to slide out of the fixing block 17, thus removing the cover 9. This allows the equipment to adapt to different production needs more quickly, improving its flexibility and adaptability. One side of the outer wall of the second insulation barrel 4 passes through... A water pipe 22 is connected and fixedly connected to a water tank 23 at one end. A heat dissipation fin 25 is connected and fixedly connected to one side of the water tank 23. A water pump 24 is fixedly connected to the outer wall of the water pipe 22 and is also fixedly connected to the water tank 23. A control panel 2 is provided at one end of the support plate 1 and is electrically connected to the servo motor 10 and the water pump 24. Temperature sensors 26 are evenly distributed at the bottom of the inner wall of the second insulation tank 4 and are electrically connected to the control panel 2. The temperature sensors 26 transmit signals to the control panel 2, thereby allowing the water pump 24 to transport the liquid stored in the water tank 23 to the second insulation tank 4 through the water pipe 22. This reduces manual intervention, lowers the risk of operational errors, and reduces the workload of operators.

[0036] Working principle: By allowing the limiting rod 21 to slide into the fixing rod 19, the spring 20 is compressed, causing the fixing block 17 to slide out of the fixing rod 19 and the heat-conducting plate 5 to slide into the slider 7. Subsequently, due to the rebound of the spring 20, the limiting rod 21 slides out of the fixing rod 19 and into the fixing block 17, thereby fixing and limiting the required components and structures. Then, the signal transmitted by the temperature sensor 26 causes the control panel 2 to control the water pump 24 to draw the liquid continuously cooled by the heat dissipation fins 25 in the water tank 23 into the water pipe 22, and then transport it to the second insulation tank 4. Heat energy is recovered internally. Simultaneously, the rotation of the transmission rod 11 causes the worm gear 12 to rotate inside the cover 9. Subsequently, through the meshing connection between the worm gear 12 and the worm wheel 14, the worm wheel 14 drives the rotating rod 13 to rotate inside the cover 9, thereby causing the disc 15 to rotate inside the cover 9. This drives the slider 7 to slide on the disc 15, which in turn causes the slider 7 to slide on the turntable 8, and then slide between the baffles 16. This causes the slider 7 to drive the heat-conducting plate 5 and the insulating pad 6 to slide between the first insulation barrel 3 and the second insulation barrel 4, thus achieving effective heat energy recovery.
