Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery equipment, in particular to a waste heat recovery and comprehensive utilization device for an air compressor unit. Background Art

[0002] Air compressor is an important industrial equipment, mainly used to compress air and store it as energy. It compresses a large amount of air into a confined space through a specific mechanical device, such as a piston or a rotating screw, which significantly increases the pressure and density of the air, making it easier to store and use it more efficiently. This equipment plays a key role in many industrial fields, such as manufacturing, construction, and food processing.

[0003] The screw air compressor pressurizes the gas through the mechanical movement of the master and slave screws. During the compression process, the rotation of the screw will limit the gap between the outer shell of the compression chamber and the rotating screw, so that the gas is compressed. This compression process will cause the pressure and temperature of the gas to gradually increase, thereby generating a certain amount of heat. In order to control this heat, the screw and other moving parts are generally lubricated with lubricating oil, and through the circulation of the lubricating oil, the heat is brought to the heat dissipation device for further heat dissipation. Some screw air compressors also use heat exchangers to recover the waste heat of the lubricating oil. Through the heat exchange process, the cooling water is heated and the lubricating oil is cooled, thereby realizing heat recovery and reuse. However, most heat exchangers are external, which will increase the overall size of the air compressor unit. At the same time, when the heat exchange fins of the traditional heat exchanger are covered with scale and affect the heat exchange effect, it is difficult to quickly disassemble and replace the heat exchange fins.

[0023] like Figure 2-Figure 3As shown, a plurality of heat-conducting sleeves 10 are fixedly installed on the left end surface of the heat sink 6. The heat sink 6 can be stably inserted and installed on the outside of the lubricating oil circulation pipe 5 with the help of the heat-conducting sleeves 10, and the heat of the lubricating oil in the lubricating oil circulation pipe 5 is effectively conducted to the heat sink 6. A water inlet seat 11 is fixedly installed on the front end surface of the heat sink 6, and a water outlet seat 12 is fixedly installed on the rear end surface of the heat sink 6. The installation height of the water inlet seat 11 is higher than the water outlet seat 12.
