It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1

[0025] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a waste heat recovery device for glass furnace exhaust gas, comprising a box body 1. The bottom surface of the box body 1 is fixedly installed with support feet, and the support feet are evenly distributed at the four corners of the bottom surface of the box body 1. The support feet are connected to the bottom surface of the box body 1 by means of bolts or welding. Such a connection method can ensure the stability and support force of the equipment and is convenient for later disassembly and maintenance. The material of the support feet can be selected as high-temperature resistant stainless steel, which can resist high temperature and corrosion in the furnace environment and ensure the long-term stable operation of the equipment. One side of the box body 1 is communicated with an air outlet pipe 2, and the other side is communicated with an air inlet pipe 3. The air outlet pipe 2 and the air inlet pipe 3 are fixed by means of flange or threaded connection. This connection method can not only ensure the sealing of gas flow but also facilitate later disassembly and cleaning and maintenance. The air inlet pipe 3 is used to connect the exhaust gas of the glass furnace. After the exhaust gas enters the box body 1, heat is recovered through a heat exchange device. The top surface of the box body 1 is communicated with a liquid inlet pipe 4, and the bottom surface of the box body 1 is communicated with a liquid outlet pipe 5. One end of each of the liquid inlet pipe 4 and the liquid outlet pipe 5 is communicated with a water distributor 6, and the surface of the water distributor 6 is communicated with heat exchange pipes 7. The heat exchange pipes 7 are arranged in a circular shape on the surface of the water distributor 6. The liquid inlet pipe 4 and the liquid outlet pipe 5 can be connected by welding or flange. This connection method can ensure the sealing and pressure resistance during the flow of hot water. The material of the water distributor 6 and the heat exchange pipes 7 can be selected as copper or stainless steel. Copper has good thermal conductivity and can effectively improve the waste heat recovery efficiency of the exhaust gas, while stainless steel has higher corrosion resistance and can ensure the durability and long life of the system. Hot water enters the heat exchange pipes 7 through the liquid inlet pipe 4 and is heated by the high-temperature exhaust gas in the heat exchange pipes 7, thereby recovering the waste heat in the exhaust gas. Finally, the heated hot water is discharged from the liquid outlet pipe 5 for subsequent use.

[0026] Please refer to Figures 1 - 5, an installation disk 8 is fixedly installed on the inner side of the box body 1, and a filter plate 9 is fixedly installed on the side surface of the installation disk 8. The installation disk 8 is connected by means of bolts or riveting, and this connection method can ensure the stability of the installation disk 8 and prevent the vibration generated by the exhaust gas flow from affecting the filtering effect of the filter plate 9. The filter plate 9 is used to filter the particulate matter in the exhaust gas, prevent pollutants from being directly discharged into the atmosphere, and improve the environmental protection effect. The material of the filter plate 9 can be high-temperature-resistant stainless steel or ceramic fiber. The stainless steel filter plate has high strength and wear resistance and is suitable for long-term use, while the ceramic fiber has good heat resistance and chemical corrosion resistance. A rotating rod 10 is arranged through the side surface of the filter plate 9. One end of the rotating rod 10 is fixedly installed with a fan blade 11, and the other end is fixedly installed with a vertical plate 12. The rotating rod 10 is connected to the filter plate 9 by means of a bearing or a sliding shaft sleeve to ensure that the rotating rod 10 can rotate flexibly, reduce friction, and extend the service life. The bearing connection method has the advantages of low friction and high efficiency and is suitable for the long-term operation of the equipment. When the exhaust gas enters the box body 1 through the intake pipe 3, the flow of the exhaust gas drives the fan blade 11 to rotate, and then drives the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the vertical plate 12 to rotate. A scraping plate 13 is fixedly installed on the side surface of the vertical plate 12, and the scraping plate 13 is attached to the filter plate 9. The material of the scraping plate 13 can be selected from wear-resistant rubber or polytetrafluoroethylene. The wear-resistant rubber has good elasticity and durability and can effectively protect the filter plate 9 from being scratched when cleaning the stains on the surface of the filter plate 9. The scraping plate 13 scrapes the surface of the filter plate 9 as the vertical plate 12 rotates, thereby cleaning the stains attached to the surface of the filter plate 9, preventing the filter plate 9 from being blocked, and improving its service life.

[0027] Embodiment 2

[0028] Please refer to Figures 4 - 5 , a collection mechanism is arranged on the surface of the box body 1. The collection mechanism includes a placement groove 14. The placement groove 14 is opened on the surface of the box body 1. A sliding groove 15 is opened on the inner wall of the placement groove 14. A slider 17 is slidably connected to the inner wall of the sliding groove 15, and a collection box 16 is fixedly installed on the top surface of the slider 17. The slider 17 is slidably connected to the sliding groove 15 by means of a guiding slide rail or a bearing to ensure that the collection box 16 slides smoothly and reduces friction and jamming phenomena. The matching design of the slider 17 and the sliding groove 15 simplifies the installation and disassembly process of the collection box 16, and the sliding connection method can improve the convenience and accuracy of the operation. An insertion hole 18 is opened on the inner wall of the box body 1, and an insertion post 19 is fixedly installed on the back surface of the collection box 16. The insertion post 19 is adapted to the size of the insertion hole 18, and a rubber strip 20 is fixedly installed on the surface of the insertion post 19. The material of the rubber strip 20 is natural rubber, which has good elasticity and sealing performance and can stably fix the collection box 16 on the box body 1 through friction. The rubber strips 20 are arranged in a circular shape on the surface of the insertion post 19, effectively improving the fixing effect of the collection box 16.

[0029] Working principle: The waste gas entering the glass furnace through the air outlet pipe 3 enters the heat storage water through the liquid inlet pipe 4. After the heat storage water enters the heat exchange pipe 7, it can be heated by the waste gas. At this time, the heat in the waste gas can be recovered. Finally, the heated heat storage water is discharged from the liquid outlet pipe 5. When the waste gas is discharged through the air outlet pipe 3, the filter plate 9 can filter the waste gas, thus improving the environmental protection effect. During the outward flow of the waste gas, the fan blade 11 can be driven to rotate. At this time, the fan blade 11 can drive the rotating rod 10 to rotate. Subsequently, the rotating rod 10 can drive the vertical plate 12 to rotate. At this time, the vertical plate 12 drives the scraper 13 to scrape the surface of the filter plate 9. At this time, the stains on the filter plate 9 can be cleaned, thereby reducing the probability of blockage of the filter plate 9 and increasing the service life of the filter plate 9. The utility model drives the rotation of the fan blade 11 and the rotating rod 10 through the flow of the waste gas, and then drives the scraper 13 to automatically scrape and clean the filter plate 9, which can effectively remove the stains on the surface of the filter plate 9, avoid blockage, extend the service life of the filter plate 9, reduce the need for manual cleaning, and reduce the maintenance cost. And the waste gas is filtered by the filter plate 9, effectively reducing the emission of harmful substances in the waste gas, improving the environmental protection effect, reducing pollution. At the same time, the mechanical linkage of the fan blade 11, the rotating rod 10 and the scraper 13 is driven by the flow of the waste gas itself for automatic cleaning operation, without additional power or control system. The provided collection box 16 can collect the stains brushed off the surface of the filter plate 9. When the stains need to be recycled, the staff only needs to pull the collection box 16 outwards. Subsequently, the collection box 16 can drive the plug post 19 to leave the jack 18, and at the same time, the collection box 16 drives the slider 17 to slide in the chute 15. At this time, the collection box 16 can be removed. When installing the collection box 16, only need to align the slider 17 under the collection box 16 and slide it into the chute 15 until the plug post 19 is inserted into the jack 18. At this time, due to the friction force generated between the rubber strip 20 and the jack 18, the collection box 16 can be fixed. The utility model has a detachable collection box 16. The staff only needs a simple pulling operation to easily remove and replace the collection box 16, improving the convenience of collecting and treating stains, reducing the complexity of cleaning and maintenance. At the same time, the collection box 16 is designed with the cooperation of the slider 17 and the plug post 19, simplifying the installation process. The staff can quickly align the collection box 16 with the chute 15 and insert it. After the plug post 19 enters the jack 18, it is fixed by the friction force, making the installation process simple and efficient, reducing the operation time and the probability of errors. And because the stains on the filter plate 9 are brushed off by the scraper 13 and collected in the collection box 16, this reduces the dependence on manual cleaning, ensures that the surface of the filter plate 9 always maintains a high cleanliness, thereby extending the service life of the filter plate 9 and maintaining the efficient operation of the equipment.

[0030] The above are only the preferred embodiments of the present utility model and do not limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
