[0001] The invention relates to the technical field of waste heat utilization, and in particular to a waste heat utilization device. Background Art

[0002] HVAC system plays a vital role in modern building environment. Its functions cover heating, ventilation and air conditioning, aiming to provide residents with a comfortable and healthy living or working environment. Specifically, heating (heating) provides necessary heat to the building to ensure that the indoor temperature is maintained within a suitable range; ventilation promotes the exchange of indoor and outdoor air by natural or mechanical means, effectively removes dirty air and introduces fresh air; air conditioning further fine-tunes parameters such as air humidity, cleanliness, and airflow speed to meet the special requirements of different production activities and life needs for the indoor environment.

[0003] However, in actual applications, traditional HVAC systems often leave some residual heat during the heating process. This energy that is not effectively utilized not only causes a huge waste of energy, but also increases operating costs. In order to address this problem, waste heat utilization devices have emerged to collect and reuse this residual waste heat to improve energy efficiency.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0033] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] See also Figure 1-3The present embodiment provides a waste heat utilization device, including: an air storage pipe 1, a water storage pipe 2 and a filter assembly 3. The two ends of the air storage pipe 1 are respectively provided with an air inlet 4 and an air outlet 5. The air inlet 4 is provided with a first air pipe 6. The filter assembly 3 is sealed and connected to the first air pipe 6 and the filter assembly 3 is detachable. The first air pipe 6 is used to receive hot air and input it into the air storage pipe 1. The water storage pipe 2 is arranged around the air storage pipe 1 and is used to exchange heat with the air storage pipe 1.

[0035] In this embodiment, the water storage pipe 2 surrounds the gas storage pipe 1. This layout significantly increases the heat exchange area between the gas storage pipe 1 and the water storage pipe 2. Specifically, when high-temperature or low-temperature gas is stored inside the gas storage tank, these gases will transfer their temperature to the surrounding water through the gas storage pipe 1. Since the water storage pipe 2 tightly wraps the gas storage pipe 1, an efficient heat conduction path is formed between the two, so that heat can be transferred from the gas storage pipe 1 to the water storage pipe 2 more quickly and evenly, or vice versa, so that heat can be transferred from the water storage pipe 2 to the gas storage pipe 1 more quickly and evenly, depending on the actual application scenario. In this way, not only the thermal conductivity of the entire system is improved, but also the efficiency and stability of the energy conversion process are guaranteed. At the same time, the filter assembly 3 is sealed and connected to the first air pipe 6, and the filter assembly 3 is detachable, so that the filter assembly 3 can take into account both detachability and airtightness, thereby improving the convenience and practicality of the device.

[0036] The waste heat utilization device of this embodiment can be used not only in HVAC, but also in other equipment that needs to collect and utilize waste heat. That is, the first air pipe 6 can be used to access the hot air (i.e., waste heat) of the HVAC, and can also be used to access the hot air of other equipment.

[0037] In this embodiment, please refer to Figure 3 and Figure 4 , and also includes: a cleaning component 7 and a guide rail 8, the guide rail 8 is installed in the air storage pipe 1 along the air inlet 4 to the air outlet 5, and the cleaning component 7 is slidably installed on the guide rail 8.

[0038] The cleaning assembly 7 can slide along the guide rail 8 from the air inlet 4 to the air outlet 5, ensuring that all areas inside the air storage pipe 1 can be thoroughly cleaned. This design avoids the cleaning dead corners that may exist in traditional cleaning methods and improves the cleaning efficiency and quality. The guide rail 8 provides a stable sliding track for the cleaning assembly 7, ensuring that the movement trajectory of the assembly always remains on the predetermined path during the cleaning process. This stability helps to reduce potential failures caused by shaking or deviation of the cleaning assembly 7, and improves the reliability and stability of the entire system.

[0039] Specifically, the cleaning assembly 7 includes: an inner ring 9, an outer ring 10, multiple cleaning pieces 11 and multiple guide pieces 12. The inner ring 9 is slidably and rotatably installed on the guide rail 8, multiple guide pieces 12 are installed between the inner ring 9 and the outer ring 10, and multiple cleaning pieces 11 are installed on the outer ring 10 on one side close to the inner wall of the gas storage pipe 1.

[0040] When the air storage pipe 1 needs to be cleaned, air is introduced from the air outlet 5. Due to the obstruction of the inner ring 9, the outer ring 10, the plurality of cleaning members 11 and the plurality of guide members 12, the wind force will push the cleaning assembly 7 to slide along the guide rail 8 from the air outlet 5 to the air inlet 4. At the same time, due to the existence of the guide member 12, the wind force will drive the outer ring 10 to rotate, so that the cleaning member 11 can fully clean the inner wall of the air storage pipe 1 until the inner ring 9 is close to the first air pipe 6, and the cleaning assembly 7 completes the comprehensive cleaning of the air storage pipe 1. When heat exchange is then performed, the hot air will push the cleaning assembly 7 to slide along the guide rail 8 to the air outlet 5.

[0041] Compared with the existing manual or electric cleaning methods of the gas storage pipe 1, the present embodiment uses wind power to drive the cleaning component 11 to clean the gas storage pipe 1, which not only greatly simplifies the operation process, but also allows the user to complete the cleaning work without manual intervention; at the same time, since the entire process relies on wind power, there is no need to add additional lines and equipment, and the overall structure of the device is simple.

[0042] In this embodiment, please refer to Figure 5 and Figure 6 The inner ring 9 includes: an inner sleeve 13 and an outer sleeve 14. The inner sleeve 13 is slidably installed on the guide rail 8 along the length direction of the guide rail 8. A plurality of guide members 12 are installed between the outer sleeve 14 and the outer ring 10. One of the inner sleeve 13 and the outer sleeve 14 is provided with a sliding groove 15, and the other is provided with a slider 16. The slider 16 is slidably installed in the sliding groove 15.

[0043] The design of this structure makes it relatively easy to install and remove the inner sleeve 13 and the outer sleeve 14. This design not only simplifies the installation process, but also facilitates subsequent maintenance and servicing. When a component needs to be replaced or repaired, it can be easily removed without large-scale disassembly of the entire system.

[0044] Among them, the sliding groove 15 can be an arc-shaped sliding groove. When air is introduced, the wind force will push the outer ring 10 and the outer sleeve 14 to rotate under the action of the guide member 12. The outer sleeve 14 will slide in the arc-shaped sliding groove and finally abut against the inner wall of the arc-shaped sliding groove to drive the inner sleeve 13 to rotate together.

[0045] The sliding groove 15 can also be an annular sliding groove. In this way, when air is introduced, the wind force will push the outer ring 10 and the outer sleeve 14 to rotate under the action of the guide member 12, and the outer sleeve 14 will continue to rotate along the annular sliding groove. At the same time, the outer sleeve 14 generates a force on the inner sleeve 13 to push the inner sleeve 13 to slide along the guide rail 8.

[0046] In some embodiments, the inner sleeve 13 and the outer sleeve 14 are integrated, that is, the inner ring 9 is a whole, and the inner sleeve 13 and the outer sleeve 14 are integrated and can be connected by tight fit or welding to form a more stable overall structure. This design can effectively improve the overall strength and rigidity of the structure, so that it can withstand greater loads and stresses.

[0047] In this embodiment, a plurality of sliders 16 are provided, and the plurality of sliders 16 are slidably installed in the sliding groove 15 .

[0048] Multiple sliders 16 share the load, which can improve the stability of the entire structure. When subjected to large external forces or impacts, multiple sliders 16 can work together to disperse stress and avoid structural damage caused by excessive force on a single point. The sliding fit between the slider 16 and the sliding groove 15 is usually highly reliable. Through reasonable design and manufacturing, it can ensure that the slider 16 moves smoothly and stably in the sliding groove 15, reduce friction and wear, and extend the service life.

[0049] In this embodiment, the guide member 12 is similar to the blade structure of a fan. When water flow or air flow rushes toward the guide member 12, due to the inclination angle of the guide member 12, the fluid will be guided to flow along the guide member 12, thereby driving the guide member 12 and the components connected thereto to rotate.

[0050] In this embodiment, the cleaning member 11 and the outer ring 10 can be integrated or separated, that is, the cleaning member 11 and the outer ring 10 are detachably connected. The cleaning member 11 is provided with a clamping protrusion or a clamping groove, and the outer ring 10 is provided with a clamping groove or a clamping protrusion on one side close to the inner wall of the gas storage pipe 1, so that the cleaning member 11 and the outer ring 10 are clamped to achieve a detachable connection between the cleaning member 11 and the outer ring 10, so that the cleaning member 11 can be replaced easily.

[0051] In this embodiment, the cleaning member 11 can be set to a retractable structure. The retractable cleaning member 11 can be adjusted according to the size and shape of different spaces to ensure that the cleaning work can be fully covered without leaving any dead corners. In different working environments or application scenarios, the cleaning requirements may be different. The retractable cleaning member 11 can flexibly adjust the length or shape to meet different cleaning needs.

[0052] Among them, the cleaning piece 11 can be a brush or a rubber brush that can clean the stubborn dust on the inner wall of the air storage pipe 1. When the cleaning piece 11 moves with the outer ring 10 to a position where it can clean the inner wall of the air storage pipe 1, the cleaning piece 11 rotates with the outer ring 10 to clean the circumference of the inner wall of the air storage pipe 1.

[0053] In this embodiment, please refer to Figure 4 , and further includes: two mounting components 17 , the two mounting components 17 are respectively mounted in the air inlet 4 and the air outlet 5 , and the two ends of the guide rail 8 are respectively mounted on the two mounting components 17 .

[0054] By mounting the two ends of the guide rail 8 on the mounting components 17 of the air inlet 4 and the air outlet 5, a stable support structure is formed. This design enhances the stability of the structure, especially when subjected to fluid pressure or external loads, and can effectively prevent the guide rail 8 from being deformed or loosened. At the same time, the two mounting components 17 are respectively mounted in the air inlet 4 and the air outlet 5, making the installation process of the guide rail 8 easier. It is only necessary to fix the two ends of the guide rail 8 on the corresponding mounting components 17, without complicated adjustment and calibration.

[0055] Furthermore, the mounting assembly 17 includes: a mounting seat 18 and a plurality of support members 19 , one end of the plurality of support members 19 is connected to the mounting seat 18 , the other end of the plurality of support members 19 is connected to the inner wall of the gas storage pipe 1 , and the mounting seat 18 is connected to the guide rail 8 .

[0056] The mounting assembly 17 composed of the mounting seat 18 and the plurality of supporting members 19 provides a solid support for the guide rail 8. This multi-point support method can significantly enhance the stability of the guide rail 8, thereby ensuring the stability of the cleaning assembly 7 sliding on the guide rail 8.

[0057] In this embodiment, the support member 19 can adopt a retractable structure, which can improve the versatility of the installation assembly 17 and make it adaptable to gas storage pipes 1 of different sizes and shapes. By adjusting the number and position of the support members 19, the support requirements of various gas storage pipes 1 can be flexibly met. In practical applications, the installation assembly 17 can be adjusted and optimized as needed. For example, by changing the length or angle of the support member 19, it can adapt to different gas storage pipes 1.

[0058] In this embodiment, please refer to Figure 7 The filter assembly 3 includes: two first shells 20, a second shell 21 and a filter element 22. The two first shells 20 are respectively installed at both ends of the second shell 21, one of the first shells 20 is movably connected to the first air pipe 6, and the filter element 22 is installed in the second shell 21.

[0059] By tightly connecting the first housing 20 with the second housing 21 and ensuring that the filter element 22 is correctly installed in the second housing 21, leakage of gas or liquid can be effectively prevented, and the sealing performance of the filter assembly 3 can be improved. When the filter element 22 needs to be replaced or cleaned, the first housing 20 can be easily disassembled without disassembling the entire filter assembly 3. This design reduces the complexity and time cost of maintenance work.

[0060] In this embodiment, one of the first shell 20 and the second shell 21 is provided with an internal thread 23 (such as Figure 8 As shown), the other is provided with an external thread 24 (as Figure 7 As shown), the internal thread 23 is threadedly connected with the external thread 24.

[0061] Threaded connection is a mechanical connection method that achieves connection through the mutual engagement of threads and has a high connection strength. This structure can withstand greater pressure and torque, ensuring the stability and safety of the first shell 20 and the second shell 21. When the threaded connection is subjected to vibration or impact, the mutual engagement of the threads can effectively prevent the first shell 20 and the second shell 21 from loosening, thereby improving the reliability of the device. In addition, the close fit between the internal thread 23 and the external thread 24 can effectively prevent gas leakage and ensure that the device has a high thermal conductivity.

[0062] In this embodiment, one end of the first housing 20 is a threaded structure, and the other end is connected to a flange 25 (such as Figure 1 As shown in the figure, for example, the first housing 20 is connected to the flange 25 on the first air pipe 6 through the flange 25 thereon. The flange connection is a connection method in which two flanges 25 are tightly pressed together by bolts, and has a high connection strength. This structure can withstand greater pressure and tension to ensure the stability of the connection. At the same time, the structure of the flange connection is relatively simple. When installing, you only need to align the two flanges 25 and tighten them with bolts. This connection method does not require complicated processes and equipment, reducing the difficulty and cost of installation. In addition, when it is necessary to disassemble or replace parts, you only need to loosen the bolts to easily separate the two flanges 25. This structure makes maintenance work more convenient and quick, and reduces maintenance costs.

[0063] In this embodiment, please refer to Fig. 9 and 10 The filter assembly 3 further includes an elastic filler 26 , which is disposed between the internal thread 23 and the external thread 24 .

[0064] The elastic filler 26 has good elasticity and plasticity due to the special properties of its material, such as rubber, silicone or other elastic materials. When the first shell 20 and the second shell 21 are connected through the internal thread 23 and the external thread 24, the elastic filler 26 will be compressed and filled in the small gap between the threads. This filling effect can further prevent the leakage of gas or liquid and improve the sealing performance of the filter assembly 3. At the same time, due to tolerance problems in the manufacturing process, there may be slight size differences between the threaded parts of the first shell 20 and the second shell 21. The elastic filler 26 can adapt to this tolerance difference and ensure a tight connection between the two shells.

[0065] In this embodiment, the filter element 22 includes: at least one activated carbon 27 and / or at least one porous silica gel 28 (such as Figure 7 As shown in the figure, for example, an activated carbon 27 and two porous silica gels 28 may be used, and the two porous silica gels 28 may be placed on both sides of the activated carbon 27. Placing the two porous silica gels 28 on both sides of the activated carbon 27 may form an efficient filtration layer. The porous silica gel 28 first filters out larger particles and impurities, providing a relatively clean filtration environment for the activated carbon 27, thereby improving the adsorption efficiency and life of the activated carbon 27. The activated carbon 27 further adsorbs and removes small molecular pollutants in the solution, ensuring that the water quality or air quality after filtration reaches a higher standard.

[0066] Activated carbon 27 has a large specific surface area due to its porous structure, and can absorb a large amount of impurities and pollutants in gases and liquids. At the same time, activated carbon 27 has a strong adsorption capacity for organic matter, colloidal silicon, residual chlorine, heavy metal ions, etc., and can effectively remove odors, color, etc. in water. Secondly, the adsorption capacity of activated carbon 27 is also affected by the oxygen-containing functional groups on the non-crystalline part of its surface. These functional groups can enhance the adsorption effect of activated carbon 27 on pollutants.

[0067] Porous silica gel 28 is a material with high adsorption and stability, which can adsorb impurities in a variety of gases and liquids. The adsorption capacity of porous silica gel 28 mainly comes from its porous structure, which can accommodate and fix a large number of impurity molecules. Porous silica gel 28 also has good thermal and chemical stability, and can maintain its adsorption performance in a wide range of temperature and chemical environments.

[0068] It should be noted that the filter element 22 may also be made of other filter materials, such as filter screens, membrane separation materials, nanomaterials, and synthetic fiber filter materials, etc. This embodiment does not limit this, and the user may select a specific filter material according to actual circumstances.

[0069] When the filter element 22 needs to be replaced, the upper and lower flanges 25 of the filter assembly 3 are removed, and then the entire assembly is removed, and then the first shell 20 and the second shell 21 are directly unscrewed, and then the porous silica gel 28 and activated carbon 27 inside are removed and replaced. During installation, the porous silica gel 28 and activated carbon 27 will be squeezed and fixed by the threaded boss portion of the first shell 20, and no additional installation means are required.

[0070] In this embodiment, please refer to Figure 1 , further comprising: a valve 29 , a second air pipe 30 is provided on the air outlet 5 , and the valve 29 is installed on the second air pipe 30 .

[0071] The connection between the valve 29 and the second gas pipe 30 is usually sealed to effectively prevent gas leakage, which can not only reduce resource waste but also avoid potential safety hazards.

[0072] In this embodiment, it also includes: an insulation box 31 (such as Figure 1 As shown), the gas storage pipe 1 and the water storage pipe 2 are both installed in the heat preservation box 31.

[0073] The heat preservation performance of the heat preservation box 31 can effectively reduce the heat exchange between the internal medium and the external environment, thereby reducing energy loss and improving the heat conduction efficiency between the gas storage pipe 1 and the water storage pipe 2.

[0074] In this embodiment, the two ends of the water storage pipe 2 are respectively connected to a water inlet pipe 32 and a water outlet pipe 33 (such as Figure 1 shown).

[0075] The water storage pipe 2 is connected to the water inlet pipe 32 and the water outlet pipe 33, so as to continuously receive and release water, thereby ensuring the continuity and stability of the water supply system.

[0076] In this embodiment, the gas storage pipe 1 and the water storage pipe 2 adopt a continuously curved structure and form a wave-like curved structure.

[0077] The wavy structure can change the flow direction of the fluid to a certain extent, thereby reducing the resistance of the fluid in the pipeline and improving the fluid transmission efficiency. At the same time, the wavy structure can also increase the heat exchange area between the gas storage pipe 1 and the water storage pipe 2, thereby improving the heat conduction efficiency between the gas storage pipe 1 and the water storage pipe 2, and further improving the heat conduction effect.

[0078] The working principle of the waste heat utilization device of this embodiment is: the hot air is filtered through the porous silica gel 28 and the activated carbon 27 in the filter component 3, and then the hot air is sent to the first air pipe 6 and stored in the air storage pipe 1 in the insulation box 31. The heat of the hot air is gradually transferred to the water storage pipe 2. After the temperature of the hot air drops, the valve 29 is opened to release it from the second air pipe 30.

[0079] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.

[0080] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive.
