Description

Technical Field

[0001] This invention relates to the field of air compressor technology, and in particular to an energy-saving structure for air compressors based on waste heat recovery. Background Technology

[0002] In industrial production, air compressors are crucial power equipment, but they generate a large amount of high-temperature waste heat during operation. This heat is usually discharged directly into the atmosphere through air cooling or water cooling, resulting in huge energy waste. Although existing waste heat recovery technologies can partially recover heat energy for purposes such as heating water, they still have significant drawbacks in practical applications. Traditional heat exchangers have fixed structures, and after long-term operation, the outer surface of the heat exchange pipes is prone to deposits such as scale and oil, which seriously degrades the heat transfer efficiency and causes the recovery benefits to decrease sharply over time. Cleaning and maintenance often require shutdown and disassembly, which is cumbersome and time-consuming, affecting continuous production, and the cleaning is not thorough.

[0003] Therefore, in order to address the above problems, an energy-saving structure for air compressors based on waste heat recovery is now being developed. Summary of the Invention

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] An energy-saving structure for air compressors based on waste heat recovery, such as Figures 1-9As shown, the system includes an air tank 1, an air compressor 2 mounted on the upper left side of the air tank 1, and a drive motor 3 mounted on the upper right side of the air tank 1. The drive motor 3 drives the air compressor 2. A mounting base 4 is placed on the front left side of the air tank 1. An air outlet pipe 41 and a first water outlet pipe 42 are located at the bottom of the mounting base 4. A support base 43 is located at the bottom inside the mounting base 4. Two second mounting plates 6 are bolted to the mounting base 4, forming a cylindrical structure. A third mounting plate 7 is located between the tops of the second mounting plates 6. A space is provided between the second mounting plates 6 and the third mounting plate 7. A heat exchange assembly 8 is provided, including a connecting pipe 81. The connecting pipe 81 is placed on the mounting base 4. A conveying pipe 82 is provided on the top of the connecting pipe 81. A connecting pipe 81 is also installed between the tops of the conveying pipes 82. The upper part of the conveying pipe 82 is connected through to the third mounting plate 7. A sealing ring 83 is provided on the third mounting plate 7. The sealing ring 83 is perpendicular to the conveying pipe 82. The cleaning assembly 9 includes a drive assembly 91. The drive assembly 91 is provided on the top of the third mounting plate 7. The output shaft of the drive assembly 91 is oriented downwards. A lead screw is installed on the output shaft of the drive assembly 91. The lead screw is connected to the mounting base 4. The mounting base 4 is rotatably connected, and a first mounting component 92 is threaded onto the lead screw. Multiple second mounting components 93 are disposed on the outer side of the first mounting component 92. A third mounting component 94 is rotatably disposed on the outer side of each of the second mounting components 93. A cleaning component 95 is slidably connected to the inner side of each of the second and third mounting components 93. The cleaning components 95 are used to clean the outer surface of the conveying pipe 82. Two first springs 96 are connected between each cleaning component 95 and each adjacent second or third mounting component 94. Each third mounting component 94 is slidably connected to a latch 97. The latch 97 is connected to the adjacent second or third mounting component 94. Each of the three mounting components 94 is connected to a second spring 98. Each of the latches 97 has a pull ring on its top and can engage with the adjacent second mounting component 93. Multiple elastic plates 10 are mounted on the first mounting component 92. The elastic plates 10 are distributed crosswise between the conveying pipes 82. A scraping ring is connected between the outer sides of the elastic plates 10. A backflushing pipe 12 is provided on the top of the third mounting plate 7. The backflushing pipe 12 is used to backflush and clean the inside of the device. A second water outlet pipe 13 is provided at the bottom of the mounting base 4. The second water outlet pipe 13 is used to discharge the cleaning water flow. The top of the mounting base 4 is an inclined structure 15 to facilitate the collection of water flow.

[0028] It should be noted that after the drive motor 3 starts, it drives the air compressor 2 to compress the air. The compressed air is then sent to the air storage tank 1 for storage. During this process, the air compressor 2 generates a large amount of heat energy due to the compression action. This heat energy is effectively utilized through the waste heat recovery system. The hot air or hot oil generated by the air compressor 2 is introduced into the mounting base 4 area through pipes. The mounting base 4 is located on the left front side of the air storage tank 1, and a support base 43 is provided inside to stabilize the structure. The bottom of the mounting base 4 is connected to the air outlet pipe 41 and the first water outlet pipe 42. The air outlet pipe 41 is used to discharge the cooled air or gas, and the first water outlet pipe 42 is used to output the heated water or other fluids. The heat exchange assembly 8 includes a connecting pipe 81 and a conveying pipe 82. The connecting pipe 81 is placed on the mounting base 4. It is connected to the conveying pipe 82, which extends upward and passes through the third mounting plate 7. The third mounting plate 7 and the second mounting plate 6 together form a cylindrical structure. The second mounting plate 6 is fixed by bolts to provide mechanical support. The conveying pipe 82 is sealed at the third mounting plate 7 by a sealing ring 83 to prevent media leakage. The sealing ring 83 is set perpendicularly to the conveying pipe 82 to ensure sealing. When the hot medium flows from the air compressor 2 into the connecting pipe 81 and the conveying pipe 82, its heat is transferred through the wall of the conveying pipe 82 to the space inside the mounting base 4. Cold medium, such as water, can flow into the mounting base 4. The cold medium flows in from the inlet, exchanges heat with the hot conveying pipe 82, absorbs heat and rises in temperature, becoming hot water or a hot fluid, and then flows out from the first outlet pipe 42. It can be used for industrial production or domestic hot water, thus achieving energy saving. To maintain heat exchange efficiency and prevent scale buildup on the outer surface of the conveying pipe 82 due to long-term use, the cleaning component 9 is periodically activated for cleaning. The cleaning component 9 includes a drive component 91, which is mounted on the top of the third mounting plate 7. Its output shaft is connected downwards to a lead screw, which is rotatably connected to the mounting base 4. When the drive component 91 is activated, the lead screw rotates, causing the threaded first mounting member 92 to move up and down. Multiple second mounting members 93 are provided on the outer side of the first mounting member 92, and third mounting members 94 are rotatably provided on the outer side of the second mounting members 93. A cleaning component 95 is slidably connected to the inner sides of the second mounting members 93 and the third mounting members 94. The cleaning component 95 is activated by the action of a first spring 96. The cleaning component 95 remains in close contact with the outer surface of the conveying pipe 82. As the first mounting component 92 moves, the cleaning component 95 scrapes along the surface of the conveying pipe 82 to remove dirt. The latch 97 on the third mounting component 94 is held in place by the second spring 98, engaging with the second mounting component 93 to fix the position of the cleaning component 95. If necessary, the cleaning component 95 can be released for maintenance by pulling the latch 97 with a pull ring. In addition, an elastic plate 10 is installed on the first mounting component 92, which is crisscrossed between the conveying pipes 82. The outer side of the elastic plate 10 is connected to the scraping ring. During movement, the elastic plate 10 adapts to the gaps in the conveying pipes 82, and the scraping ring further scrapes away stubborn dirt, enhancing the cleaning effect. For thorough cleaning, a backflushing pipe 12 is also provided. The backflushing pipe 12 is installed on the top of the third mounting plate 7. When backflushing cleaning is required,High-pressure water or cleaning fluid is introduced through backflushing pipe 12. The water flow reverses direction to flush the inside of mounting base 4 and the outer surface of conveying pipe 82, loosening and removing accumulated scale. The wastewater after cleaning is discharged through the second outlet pipe 13 at the bottom of mounting base 4. The top of mounting base 4 is designed with an inclined structure 15 to facilitate water flow convergence and guidance, ensuring that cleaning fluid and wastewater can flow smoothly to the outlet and avoid water accumulation. The entire working process is continuous. When air compressor 2 is running, hot medium continuously flows through conveying pipe 82, and heat is absorbed by cold medium, realizing waste heat recovery, energy saving and consumption reduction. At the same time, cleaning component 9 can be manually or automatically started periodically. Through drive component 91, cleaning component 95 and scraper ring clean conveying pipe 82, maintaining high heat exchange efficiency. This not only efficiently recovers waste heat but also reduces maintenance costs through automated cleaning, improving overall energy utilization.
