[0018] Please see Figure 1 This utility model provides a technical solution: a waste heat recovery type energy-saving air compressor, including a compression section, a drive section, an air inlet section, an oil-gas separator 1, and a cooling box 2. The input end of the compression section is connected to the drive end of the drive section, the air inlet section is located at the input end of the compression section, the output end of the compression section is connected to the input end of the oil-gas separator 1, the cooling box 2 is fitted around the compression section and the oil-gas separator 1, and the outlet end of the oil-gas separator 1 is provided with an exhaust pipe 3. An oil outlet pipe 4 is provided at the oil end, and the oil outlet pipe 4 is connected to the oil inlet of the compression section. A cold water tank 5 is fixedly installed at the lower end of the cooling tank 2. A cold water pipe 6 is provided at the water inlet end of the cold water tank 5. A main cooling pipe 7 is provided inside the cooling tank 2 and is connected to the upper end of the cooling tank 2. A drive cooling pipe 8 is provided inside the cooling tank 2 and is wound around the outside of the drive section. The output end of the drive cooling pipe 8 is connected to one end of the cooling tank 2. A hot water pipe 9 is provided at the other end of the cooling tank 2.

[0019] In this embodiment, an antifreeze pipe 10 is provided inside the cooling box 2. The antifreeze pipe 10 is wrapped around the outside of the air inlet, and the output end of the antifreeze pipe 10 is connected to the upper end of the cooling box 2.

[0020] In this embodiment, the compression section includes a main shaft 11 and a compression box 12. The compression box 12 is fixedly installed inside the cooling box 2. The main shaft 11 is rotatably installed inside the compression box 12. The air inlet end of the compression box 12 is connected to the output end of the air inlet section. An oil inlet end is provided below the air inlet end of the compression box 12. The oil inlet end is connected to the output end of the oil outlet pipe 4. The rear output end of the compression box 12 is connected to the input end of the oil-gas separation section 1. A screw air delivery blade is fixedly installed on the main shaft 11.

[0021] In this embodiment, the air intake section includes an air intake pipe 13, a one-way valve 14 is provided on the air intake pipe 13, a filter pipe 15 is provided on the air intake pipe 13, a heating fin 16 is fixedly installed on the outside of the air intake pipe 13, and an antifreeze pipe 10 is wound inside the heating fin 16. The air intake pipe 13 is prone to freezing, so hot water needs to be introduced for warming treatment to prevent the air intake structure from freezing and causing air intake obstruction.

[0022] In this embodiment, the driving unit includes a driving motor 17, which is fixedly installed outside the cooling box 2. The driving end of the driving motor 17 is fixedly connected to one end of the main shaft 11. A heat dissipation fin 18 is fixedly installed on the driving motor 17, and the driving cooling pipe 8 is wound inside the heat dissipation fin 18.

[0023] In this embodiment, the input ends of the driving cold pipe 8 and the main cold pipe 7 are provided with liquid delivery pumps 19.

[0024] In this embodiment, the cold water pipe 6 and the hot water pipe 9 are further configured to be connected to an external heat element 20 or a heat dissipation kit.

[0025] Its detailed connection methods are well-known technologies in this field; such as Figure 1 As shown, the equipment needs to be connected to the compressed air supply pipeline and waste heat recovery pipeline of the plant. Cold water pipe 6 and hot water pipe 9 are used to connect cooling equipment or other industrial heat elements 20 to realize the recovery and utilization of heat energy.

[0026] Start the drive motor 17 to compress air through the compression section. Ensure the air intake section can draw in air normally, and open the antifreeze pipe 10 and heating fins 16 to prevent air icing in low-temperature environments. During equipment operation, the compression process generates waste heat. The cooling tank 2 works in conjunction with the cold water tank 5, using cooling pipes and drive cooling pipes 8 to deliver cold water into the cooling tank 2 for cooling and recovery. Hot water is delivered to the external heat-using element 20 through the hot water pipe 9, for applications such as water heating, factory heating, or other production processes. The compressed air passes through the oil-gas separator 1, is purified, and then delivered to the factory's pneumatic equipment or other production lines through the exhaust pipe 3. Regularly clean the filter pipe 15 and check the water circulation of the cooling system to prevent blockages.

[0027] Check the equipment for abnormal vibrations or noises, and ensure that the drive motor 17 and the compression section operate smoothly. Air enters from the intake section, is filtered through the one-way valve 14 and the filter pipe 15, and then enters the compression section.

[0028] The drive motor 17 of the compression unit rotates the main shaft 11, which drives the components inside the compression box 12 to work and compress the air.

[0029] During compression, the equipment generates a large amount of heat. This waste heat is captured by the equipment cooling box 2. The main cooling pipe 7 and drive cooling pipe 8 within the cooling box 2 supply cold water to cool the structure inside. The drive cooling pipe 8 absorbs heat energy through the heat dissipation fins 18 outside the drive motor 17, transferring the waste heat to the cooling box 2. The main cooling pipe 7 and drive cooling pipe 8 work together to transfer excess heat to the cooling box 2 and then to the hot water pipe 9 for use by external equipment. The compressed air enters the oil-gas separator 1, separating the oil present during compression. The purified compressed air is delivered to the production line through the exhaust pipe 3, while the separated oil flows back to the compression section through the oil outlet pipe 4 for recycling. In low-temperature environments, the antifreeze pipe 10 is wrapped around the air inlet and warmed by hot water circulation to prevent air intake obstruction due to icing.

[0030] Through the hot water pipe 9, the recovered waste heat can be connected to external heat-using elements 20, such as factory heaters and production equipment, to meet their heat energy requirements and achieve sustainable utilization of waste heat.
