[0036] Reference Figures 1 to 3 According to a first aspect embodiment of the present invention, the steam waste heat utilization device includes: a support 10, a heat exchange tank 20, a heat exchange assembly 30, and an agitation assembly 40. The heat exchange tank 20 is horizontally placed on the support 10 and is used to store a cooling medium. The heat exchange assembly 30 is disposed in the heat exchange tank 20 and includes a heat exchange tube 32 and a guide plate 31. The heat exchange tube 32 is disposed in the heat exchange tank 20 and immersed in the cooling medium. The heat exchange tube 32 is connected to a steam pipe 11 connected to the outside. The guide plate 31 is disposed in the heat exchange tank 20, and the heat exchange tube 32 can be mounted on the guide plate 31. The agitation assembly 40 is disposed at both ends of the heat exchange tank 20 and is used to agitate the cooling medium in the heat exchange tank 20.

[0037] Specifically, the steam waste heat utilization device in this embodiment mainly includes a support 10, a heat exchange tank 20, a heat exchange component 30, and a stirring component 40.

[0038] The support frame 10 supports the entire device, ensuring the stable installation and operation of all components. The support frame 10 can be designed in various forms, such as a frame structure, to ensure sufficient strength and stability. The heat exchange tank 20 is placed horizontally on the support frame 10. The heat exchange tank 20 stores the cooling medium, such as cold water or other suitable fluids. The heat exchange tank 20 can be a sealed container with sufficient volume to hold enough cooling medium and be able to withstand certain pressure and temperature. The shape of the heat exchange tank 20 can be cylindrical, cuboid, or other suitable shapes. The heat exchange assembly 30 is disposed within the heat exchange tank 20. The heat exchange assembly 30 includes heat exchange tubes 32 and guide plates 31. The heat exchange tubes 32 are disposed within the heat exchange tank 20 and immersed in the cooling medium. The heat exchange tubes 32 are connected to the external steam pipe 11 to introduce steam into the heat exchange tubes 32. As the steam flows within the heat exchange tubes 32, it exchanges heat with the cooling medium, thereby utilizing the waste heat of the steam. The material and structure of the heat exchange tube 32 should possess good thermal conductivity and corrosion resistance to ensure efficient heat exchange and a long service life. A baffle plate 31 is installed in the heat exchange tank 20 to guide and support the heat exchange tube 32. The baffle plate 31 can be designed in various shapes, such as flat plates or corrugated plates, to better disperse and support the heat exchange tube 32, while promoting the flow and uniform distribution of the cooling medium in the heat exchange tank 20. The heat exchange tube 32 can be mounted on the baffle plate 31 in a multi-layered or meandering arrangement to increase the heat exchange area and efficiency. Agitators 40 are installed at both ends of the heat exchange tank 20. The agitators 40 are used to agitate the cooling medium in the heat exchange tank 20 to promote heat exchange between the cooling medium and the heat exchange tube 32. The agitators 40 can achieve the agitation effect by using a motor-driven impeller, pump, or other suitable means. Through the action of the agitators 40, the formation of localized high or low temperature zones in the heat exchange tank 20 can be effectively avoided, thereby improving the overall heat exchange efficiency of the device.

[0039] In practical applications, the steam waste heat utilization device of this utility model can operate in the following manner: First, the cooling medium is injected into the heat exchange tank 20; then, the stirring component 40 is started to make the cooling medium circulate in the heat exchange tank 20; next, steam is introduced into the heat exchange tube 32 through the steam pipe 11; when the steam flows in the heat exchange tube 32, it will have sufficient heat exchange with the cooling medium, thereby transferring the waste heat of the steam to the cooling medium; finally, after absorbing the waste heat of the steam, the cooling medium can be used for heating, hot water supply or other purposes.

[0040] Therefore, it is understood that the steam waste heat utilization device according to the embodiment of this utility model has at least the following beneficial effects: After the external steam is utilized by the steam utilization device, it is introduced into the steam waste heat utilization device through the steam pipe 11. The steam waste heat utilization device can recover and utilize the lower temperature steam after it has been used in the steam room, thereby improving the heat utilization rate of the steam. At the same time, the stirring component 40 in the steam waste heat utilization device can be used to drive the cooling medium in the heat exchange tank 20 to flow, so that the heat exchange tube 32 can be uniformly heat-exchanged, thereby improving the heat exchange efficiency.

[0041] Reference Figures 1 to 3 In some embodiments of this utility model, multiple guide plates 31 are provided, and the multiple guide plates 31 are spaced apart in the heat exchange tank 20. The guide plates 31 extend in the vertical direction, and the stirring components 40 are located at both ends of the guide plates 31.

[0042] Specifically, multiple guide vanes 31 form spaced intervals within the heat exchange tank 20. These spaces facilitate the arrangement of the heat exchange tubes 32 and allow the cooling medium to flow and exchange heat within them. The number and spacing of the guide vanes 31 can be determined based on actual heat exchange requirements and the flow characteristics of the cooling medium to achieve optimal heat exchange performance. Furthermore, agitators 40 are located at both ends of the guide vanes 31. This arrangement ensures that the agitators 40 effectively agitate the cooling medium throughout the heat exchange tank 20, particularly within the intervals between the guide vanes 31. Through the agitation of the agitators 40, the cooling medium can more fully contact the heat exchange tubes 32 and exchange heat, thereby improving heat exchange efficiency. In practical applications, when steam enters the heat exchange tubes 32 through the steam pipe 11, the residual heat of the steam is transferred to the cooling medium through the heat exchange tubes 32. Simultaneously, the activation of the agitators 40 causes the cooling medium to continuously flow and tumble within the heat exchange tank 20, further enhancing the heat exchange between the cooling medium and the heat exchange tubes 32. The arrangement of multiple guide plates 31 can optimize the flow path of the cooling medium, ensuring that the cooling medium can flow evenly through the heat exchange tubes 32 in the interval of each guide plate 31, thereby achieving more efficient and uniform heat exchange.

[0043] Reference Figures 1 to 3In some embodiments of this utility model, the guide plate 31 is provided with a clearance groove 311, which is used to avoid the heat exchange tube 32. The heat exchange tube 32 can pass through the clearance grooves 311, and the groove wall of the clearance groove 311 can abut against the outer wall of the heat exchange tube 32. Specifically, each guide plate 31 is provided with a clearance groove 311. The main function of these clearance grooves 311 is to avoid the heat exchange tube 32, so that the heat exchange tube 32 can pass through the clearance grooves 311. The design of the clearance groove 311 not only provides sufficient space for the heat exchange tube 32 to ensure that it can be stably arranged on the guide plate 31, but also enhances the connection stability and heat transfer efficiency between the heat exchange tube 32 and the guide plate 31 by the groove wall of the clearance groove 311 abutting against the outer wall of the heat exchange tube 32.

[0044] In practical applications, the shape and size of the clearance groove 311 can be customized according to the specific specifications and arrangement requirements of the heat exchange tube 32. The groove wall of the clearance groove 311 should have sufficient strength and rigidity to support the heat exchange tube 32 and withstand the vibration and impact that may occur during operation. At the same time, the groove wall of the clearance groove 311 should also be in close contact with the outer wall of the heat exchange tube 32 to reduce thermal resistance and improve heat exchange efficiency. By setting the clearance groove 311, the steam waste heat utilization device of this utility model not only achieves the stable arrangement of the heat exchange tube 32 on the guide plate 31, but also further improves the heat exchange efficiency through the close contact between the groove wall of the clearance groove 311 and the outer wall of the heat exchange tube 32. This design allows the steam to exchange heat more fully with the cooling medium when flowing in the heat exchange tube 32, thereby transferring the waste heat of the steam to the cooling medium more efficiently.

[0045] In some embodiments of this utility model, the inner wall of the heat exchange tank 20 is provided with mounting grooves (not shown in the figure), which are used to install the guide plate 31. In this embodiment of the steam waste heat utilization device, the inner wall of the heat exchange tank 20 is specially provided with mounting grooves. The main function of these mounting grooves is to install the guide plate 31, thereby ensuring that the guide plate 31 can be stably and firmly fixed inside the heat exchange tank 20.

[0046] In practical applications, the mounting groove can be customized according to the shape and size of the guide plate 31 to ensure that the guide plate 31 can be accurately embedded in the mounting groove. The depth and width of the mounting groove should be sufficient to provide adequate support area and ensure the stability and durability of the guide plate 31 after installation. At the same time, the design of the mounting groove should also take into account the ease of installation and disassembly of the guide plate 31, so as to facilitate maintenance and repair of the device. By setting the mounting groove, the steam waste heat utilization device of this utility model not only achieves stable installation of the guide plate 31 in the heat exchange tank 20, but also ensures that the spacing and layout between the guide plates 31 are more uniform and reasonable through the positioning effect of the mounting groove. This design helps to optimize the flow path of the cooling medium, improve heat exchange efficiency, and make the structure of the entire device more compact and stable.

[0047] Reference Figures 2 to 3 In some embodiments of this invention, multiple rows of heat exchange tubes 32 are arranged in a serpentine pattern within the heat exchange tank 20. In practical applications, the multiple rows of heat exchange tubes 32 can be flexibly arranged according to heat exchange requirements and the flow characteristics of the cooling medium. Each row of heat exchange tubes 32 can be independently connected to a steam source to ensure that steam is evenly distributed within each row. Simultaneously, the serpentine arrangement creates a meandering channel within the heat exchange tank 20, which not only extends the residence time of the cooling medium within the tank 20 but also increases the contact opportunities between the cooling medium and the heat exchange tubes 32, thereby improving heat exchange efficiency. The serpentine arrangement of the heat exchange tubes 32 also effectively utilizes the space within the heat exchange tank 20, especially in situations with limited space. Through reasonable arrangement and layout, the heat exchange tubes 32 can occupy minimal space within the heat exchange tank 20 while maximizing the heat exchange area. This design not only improves the compactness of the device but also reduces installation and transportation costs. Furthermore, the serpentine arrangement of the heat exchange tubes 32 helps reduce dead zones in the cooling medium, i.e., areas where the cooling medium flows slowly or stagnates. By optimizing the arrangement of the heat exchange tubes 32, it can be ensured that the cooling medium maintains a uniform flow rate within the heat exchange tank 20, thereby avoiding localized overheating or overcooling.

[0048] Reference Figure 1In some embodiments of this utility model, an inlet 21 is provided on the lower side of one end of the heat exchange tank 20, and an outlet 22 is provided on the upper side of the other end of the heat exchange tank 20. In this embodiment of the steam waste heat utilization device, an inlet 21 is provided on the lower side of one end of the heat exchange tank 20, while an outlet 22 is provided on the upper side of the other end. This design is mainly to achieve effective circulation and heat exchange of the cooling medium within the heat exchange tank 20. In practical applications, the inlet 21 is usually connected to the supply source of the cooling medium, such as a cold water pipe. When it is necessary to utilize steam waste heat, the cooling medium is injected into the heat exchange tank 20 through the inlet 21. Because the inlet 21 is located on the lower side of one end of the heat exchange tank 20, the cooling medium can enter the heat exchange tank 20 smoothly at a low speed and gradually diffuse along the bottom of the tank. The outlet 22 is located on the upper side of the other end of the heat exchange tank 20. When the cooling medium absorbs waste heat from the steam within the heat exchange tank 20, its temperature increases and its density decreases, thus naturally rising. The heated cooling medium can be easily guided out of the heat exchange tank 20 via the outlet 22 located on the upper side, and then into subsequent utilization stages, such as heating systems or hot water supply systems.

[0049] Reference Figure 1 as well as Figure 3 In some embodiments of this utility model, the heat exchange tank 20 includes a tank body 23 and a tank cover 24. The tank cover 24 is hinged to both ends of the tank body 23, and an agitator 40 is provided on the tank cover 24. In this embodiment, the steam waste heat utilization device's heat exchange tank 20 is composed of a tank body 23 and tank covers 24 at both ends. Specifically, the tank covers 24 at both ends are hinged to both ends of the tank body 23. This design allows the tank covers 24 to be easily opened and closed, facilitating inspection, cleaning, and maintenance of the interior of the heat exchange tank 20. In practical applications, the tank body 23 is the main body of the heat exchange tank 20, used to house components such as the heat exchange tubes 32 and the guide plate 31, and to withstand the pressure and temperature of the internal medium. The design of the tank body 23 should consider sufficient strength and rigidity to ensure its stability and safety during long-term operation. The lid 24 is connected to the tank body 23 by a hinge. This connection method ensures a tight connection between the lid 24 and the tank body 23, while also allowing the lid 24 to be easily opened and closed. The lid 24 is usually equipped with a sealing device, such as a sealing ring or a sealing gasket, to ensure the airtightness of the heat exchange tank 20 when closed and prevent leakage of the internal medium.

[0050] Specifically, the agitator 40 of this invention is mounted on the tank cover 24. This design not only facilitates the installation and disassembly of the agitator 40 but also allows it to better contact the cooling medium inside the heat exchange tank 20, thereby improving the agitation effect. When the agitator 40 needs to be activated, simply open the corresponding tank cover 24 for easy operation. When agitation is not required, the tank cover 24 can be closed and locked to ensure the sealing and safety of the heat exchange tank 20. Furthermore, since the tank cover 24 can be opened, it also greatly facilitates the installation, replacement, and maintenance of the heat exchange tube 32. When needed, simply open the tank cover 24 to directly operate the heat exchange tube 32 without disassembling the entire heat exchange tank 20.

[0051] Furthermore, referring to Figures 1 to 3 In some embodiments of this utility model, the stirring assembly 40 includes a driving member 41 and a stirring blade 42. The stirring blade 42 is disposed on the inner side of the heat exchange tank 20, and the driving member 41 is disposed on the outer side of the heat exchange tank 20. The output end of the driving member 41 is connected to the stirring blade 42. Specifically, in some embodiments of this utility model, the driving member 41 is a drive motor.

[0052] The steam waste heat recovery device in this embodiment mainly includes a driving component 41 and a stirring blade 42 in its agitation assembly 40. The stirring blade 42 is located inside the heat exchange tank 20, while the driving component 41 is installed on the outside of the heat exchange tank 20. This layout design not only facilitates installation and maintenance but also effectively avoids the driving component 41 from being affected by the high-temperature medium inside, thereby extending its service life. In practical applications, the stirring blade 42 is the core part of the agitation assembly 40, and its shape and structure can be customized according to the internal space of the heat exchange tank 20 and the flow characteristics of the cooling medium. The main function of the stirring blade 42 is to agitate the cooling medium inside the heat exchange tank 20 by rotation, creating strong turbulence, thereby enhancing the heat exchange effect between the cooling medium and the heat exchange tube 32.

[0053] The drive component 41 is the power source for the agitator blade 42. In this invention, the drive component 41 is preferably a drive motor. The drive motor has advantages such as simple structure, reliable operation, and convenient maintenance, and can provide sufficient power to drive the agitator blade 42 to rotate. The output end of the drive motor is connected to the agitator blade 42 through a suitable transmission device (such as a reducer, coupling, etc.) to ensure that the agitator blade 42 can rotate at a suitable speed.

[0054] Driven by the motor, the agitator blades 42 begin to rotate, generating a strong agitation. This agitation not only promotes the uniform distribution of the cooling medium within the heat exchange tank 20 but also disrupts the temperature gradient within the cooling medium, thereby improving heat exchange efficiency. Simultaneously, the agitation prevents the formation of dead zones within the heat exchange tank 20, ensuring that the cooling medium in each area can fully participate in the heat exchange process.

[0055] According to a second aspect embodiment of the present invention, the steam integrated system (not shown in the figures) includes the steam waste heat utilization device described in any of the embodiments of the first aspect. By utilizing the steam waste heat utilization device, the steam integrated system can improve its thermal efficiency, thereby significantly reducing production costs and increasing production efficiency for enterprises.

[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
