Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically a waste heat recovery device. Background Technology

[0002] Thermal energy, also known as heat or thermal power, is the energy released when matter burns or when molecules within an object move irregularly. Applications include: Power industry: Both thermal power generation and nuclear power generation utilize thermal energy for energy conversion. Industrial sectors: Steelmaking, steel rolling, blast furnace ironmaking, and non-ferrous metal smelting all require thermal energy. Transportation: The power systems of vehicles such as cars, trains, ships, and airplanes also rely on thermal energy. Daily life: Heating, air conditioning, and cooking all depend on thermal energy. Thermal energy is the energy possessed by an object due to its temperature; it is a form of internal energy. It plays a crucial role in our daily lives and scientific research. Thermal energy is a widely existing form of energy in industrial production and daily life. In industrial production processes, many devices generate a large amount of waste heat during operation. If this waste heat is not recovered and utilized, it will not only cause a huge waste of energy but also pollute the environment.

[0003] Traditional waste heat recovery devices first deliver steam into the main unit, where it contacts heat exchange tubes. A heat exchange medium flows within these tubes, recovering heat energy from the steam. However, heat recovery is concentrated on a portion of the steam's contact with the heat exchange tubes, resulting in poor recovery efficiency and slow recovery speed for other portions. To address this, some waste heat recovery devices add multiple sets of heat exchange tubes at different heights, staggering them to increase the contact area between the steam and the tubes, thus improving recovery efficiency and speed. However, this method, simply by increasing the number of heat exchange tubes, increases operating costs and maintenance complexity. Therefore, a new waste heat recovery device is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a waste heat recovery device to solve the above-mentioned technical problems that not only increase the cost of use, but also increase the difficulty of device maintenance.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste heat recovery device, comprising:

[0008] The device housing includes a liquid outlet, a liquid inlet, a drain outlet, an exhaust outlet, and a steam inlet located on the outside of the device housing. A conical guide seat is installed on the inner wall of the device housing, and a heat exchange tube is added to the outside of the conical guide seat. The liquid outlet end and the liquid inlet end of the heat exchange tube are respectively connected to the liquid outlet and the liquid inlet.

[0009] A guide rod is provided on the lower surface of the conical guide seat, and a water receiving seat is provided below the guide rod. The water receiving seat is connected to the inner wall of the device housing, and the water outlet of the water receiving seat is connected to the drain outlet.

[0010] A baffle plate, located on the lower surface of the water receiving base, has an overall trumpet-shaped design. Steam is delivered into the interior of the device housing through the steam inlet and rises along the baffle plate and through the water receiving base. When the steam comes into contact with the conical guide, it rises along the surface of the guide and concentrates around the heat exchange tubes, ensuring full contact between the steam and the tubes. The heat exchange medium is first introduced into the heat exchange tubes through the liquid inlet, and then discharged and utilized through the liquid outlet. The liquid generated on the surface of the heat exchange tubes after steam heat exchange drips into the water receiving base. Similarly, the liquid generated on the surface of the conical guide flows along the baffle rod and drips into the water receiving base, ensuring the water receiving base effectively absorbs the steam heat generated during the heat exchange. The liquid is collected and then discharged through the drain outlet. After the residual heat energy in the water vapor is recovered, the exhaust outlet can be connected to an external suction fan to discharge the gas inside the device casing. On the one hand, since the water vapor can be guided to the heat exchange tubes, the heat exchange effect and speed can be guaranteed without increasing the number of heat exchange tubes, which not only reduces the operating cost but also reduces the difficulty of device maintenance. On the other hand, the water after the water vapor heat exchange can be collected and discharged, which not only avoids water damage to the equipment and ensures the service life of the equipment but also prevents water accumulation and the reduction of heat exchange effect.

[0011] Preferably, the heat exchange tube is annular in design, and its surface is connected to the inner wall of the device housing. This ensures the stability of the heat exchange tube.

[0012] Preferably, a drive motor is mounted on the bottom of the device housing, and a rotating shaft is rotatably connected to the inner cavity of the device housing, with the drive motor and the rotating shaft coaxially connected. The drive motor drives the rotating shaft to rotate on the device housing and adjusts the direction of rotation of the rotating shaft on the device housing.

[0013] Preferably, an annular rotating plate is mounted on the top end of the rotating shaft, and an annular fixing plate is added to the top of the annular rotating plate. The rotating shaft drives the annular rotating plate to rotate within the inner cavity of the device housing.

[0014] Preferably, both the annular rotating plate and the annular fixed plate are circular in design, and the tops of the annular rotating plate and the annular fixed plate are uniformly provided with connecting holes. Water vapor inside the device housing can move upward through the connecting holes of the annular rotating plate and the annular fixed plate, while the bottom of the annular rotating plate is conical in design, which can guide the water vapor and thus prevent some water vapor from remaining near the rotating shaft.

[0015] Preferably, the bottom of the annular rotating plate is connected to the top of the rotating shaft, and the outer side of the annular fixed plate is connected to the inner wall of the device housing. When the rotating shaft drives the annular rotating plate to rotate, the connection between the annular fixed plate and the device housing cannot rotate in the same direction as the annular rotating plate, causing the connecting holes on the annular rotating plate and the annular fixed plate to be misaligned. This can intercept water vapor, thereby controlling the amount of water vapor and preventing excessive accumulation of water vapor near the heat exchange tube, which could cause damage, thus ensuring the safety of the heat exchange tube during use.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a waste heat recovery device with the following advantages:

[0018] This waste heat recovery device delivers steam through the steam inlet to the interior of the device casing, where it rises along the guide plate and through the water receiving seat. When the steam comes into contact with the conical guide seat, it rises along the surface of the guide seat and concentrates around the heat exchange tubes, ensuring full contact between the steam and the tubes. The heat exchange medium is first introduced into the heat exchange tubes through the liquid inlet, and then discharged and utilized through the liquid outlet. The liquid generated on the surface of the heat exchange tubes after steam heat exchange drips into the water receiving seat. The liquid generated on the surface of the conical guide seat after steam heat exchange... The liquid flows along the guide rod and drips into the water receiving seat, which collects the liquid produced after the water vapor heats the steam. The liquid is then discharged through the drain outlet. Since the steam can be guided to the heat exchange tubes, there is no need to increase the number of heat exchange tubes, which can ensure the heat exchange effect and speed. This not only reduces the operating cost but also reduces the difficulty of equipment maintenance. At the same time, the water after the steam heats the steam can be collected and discharged, which not only avoids water damage to the equipment and ensures the service life of the equipment but also prevents water accumulation and the reduction of heat exchange effect.

[0024] 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.

[0025] This utility model provides a technical solution, a waste heat recovery device, including: (See details) Figure 1 , Figure 2 The device housing 1, and the liquid outlet 2, liquid inlet 3, drain outlet 4, exhaust outlet 6 and steam inlet 7 are provided on the outside of the device housing 1. A conical guide seat 8 is installed on the inner wall of the device housing 1, and a heat exchange tube 9 is added on the outside of the conical guide seat 8. The liquid outlet end and liquid inlet end of the heat exchange tube 9 are respectively connected to the liquid outlet 2 and the liquid inlet 3.

[0026] Please see Figure 3 A guide rod 10 is provided on the lower surface of the conical guide seat 8, and a water receiving seat 11 is provided below the guide rod 10. The water receiving seat 11 is connected to the inner wall of the device housing 1, and the water outlet of the water receiving seat 11 is connected to the drain port 4.

[0027] A guide plate 12 is disposed on the lower surface of the water receiving seat 11, and the guide plate 12 is designed in a trumpet shape. Water vapor is transported to the interior of the device housing 1 through the steam inlet 7 and rises along the guide plate 12 through the water receiving seat 11. When the water vapor comes into contact with the conical guide seat 8, it rises along the surface of the conical guide seat 8 and concentrates around the heat exchange tube 9, ensuring full contact between the water vapor and the heat exchange tube 9. The heat exchange medium is first introduced into the heat exchange tube 9 through the liquid inlet 3, and then discharged and utilized through the liquid outlet 2. The liquid generated on the surface of the heat exchange tube 9 after heat exchange with water vapor drips into the water receiving seat 11. The liquid generated on the surface of the conical guide seat 8 after heat exchange with water vapor flows along the guide rod 10 and drips into the water receiving seat 11, ensuring that the water receiving seat 11... The liquid produced after steam heat exchange is collected and discharged through drain port 4. After the residual heat energy in the steam is recovered, exhaust port 6 can be connected to an external suction fan to discharge the gas inside the device casing 1. On the one hand, since the steam can be guided to the heat exchange tube 9, the heat exchange effect and speed can be guaranteed without increasing the number of heat exchange tubes 9, which not only reduces the cost of use but also reduces the difficulty of device maintenance. On the other hand, the water after steam heat exchange can be collected and discharged, which not only avoids water damage to the equipment and ensures the service life of the equipment but also avoids water accumulation and the reduction of heat exchange effect.

[0028] Please see Figure 3 The heat exchange tube 9 has an overall annular design, and its surface is connected to the inner wall of the device housing 1. This ensures the stability of the heat exchange tube 9.

[0029] Please see Figure 4A drive motor 14 is installed at the bottom of the device housing 1, and a rotating shaft 13 is rotatably connected to the inner cavity of the device housing 1, with the drive motor 14 and the rotating shaft 13 coaxially connected. The drive motor 14 drives the rotating shaft 13 to rotate on the device housing 1 and adjusts the direction of rotation of the rotating shaft 13 on the device housing 1. An annular rotating plate 15 is installed at the top of the rotating shaft 13, and an annular fixed plate 16 is added to the top of the annular rotating plate 15. The rotating shaft 13 drives the annular rotating plate 15 to rotate within the inner cavity of the device housing 1. Both the annular rotating plate 15 and the annular fixed plate 16 are circular in design, and the tops of the annular rotating plate 15 and the annular fixed plate 16 are evenly provided with connecting holes 5. Water vapor inside the device housing 1 can move upward through the connecting holes 5 of the annular rotating plate 15 and the annular fixed plate 16, while the bottom of the annular rotating plate 15 is tapered, which can guide the water vapor and thus prevent some water vapor from remaining near the rotating shaft 13. The bottom of the annular rotating plate 15 is connected to the top of the rotating shaft 13, and the outer side of the annular fixed plate 16 is connected to the inner wall of the device housing 1. When the rotating shaft 13 drives the annular rotating plate 15 to rotate, the connection between the annular fixed plate 16 and the device housing 1 cannot rotate in the same direction as the annular rotating plate 15, causing the connecting holes 5 on the annular rotating plate 15 and the annular fixed plate 16 to be misaligned. This can intercept water vapor, thereby controlling the amount of water vapor and preventing excessive accumulation of water vapor near the heat exchange tube 9, which could cause damage. This ensures the safety of the heat exchange tube 9 during use.

[0030] This scheme: Steam is delivered to the interior of the device housing 1 through the steam inlet 7 and rises along the guide plate 12 through the water receiving seat 11. When the steam comes into contact with the conical guide seat 8, it rises along the surface of the conical guide seat 8 and concentrates around the heat exchange tube 9, ensuring full contact between the steam and the heat exchange tube 9. The heat exchange medium is first delivered into the heat exchange tube 9 through the liquid inlet 3, and then discharged and utilized through the liquid outlet 2. The liquid generated on the surface of the heat exchange tube 9 after steam heat exchange drips into the water receiving seat 11, and the liquid generated on the surface of the conical guide seat 8 after steam heat exchange flows along the guide rod 10. The liquid drips into the water receiving base 11, allowing the water receiving base 11 to collect the liquid generated after heat exchange with the water vapor. The liquid is then discharged through the drain port 4. After the residual heat energy in the water vapor has been recovered, the exhaust port 6 can be connected to an external suction fan to discharge the gas inside the device housing 1. The drive motor 14 drives the rotating shaft 13 to rotate on the device housing 1. When the rotating shaft 13 drives the annular rotating plate 15 to rotate, the annular fixed plate 16 is connected to the device housing 1 and cannot rotate in the same direction as the annular rotating plate 15. This causes the connecting hole 5 on the annular rotating plate 15 and the annular fixed plate 16 to be misaligned, which can intercept the water vapor.
