Description

Technical Field

[0001] The invention relates to the technical field of air compressors, and more specifically, to a screw air compressor with a waste heat recovery function. Background Art

[0002] Screw air compressor is a device that compresses air and can eject high-speed flowing air. Screw air compressor provides high-quality compressed air for all walks of life with its advantages of high performance, high efficiency, maintenance-free and high reliability.

[0003] When an existing screw air compressor is working, the gas inside the device is continuously compressed, the pressure increases, and the temperature rises. When the gas is ejected, it must be cooled by the cooling system before it can be used. When the device cools its gas, the cooling method mostly uses oil cooling. After the oil absorbs the heat brought by the compressed air, it flows back to the oil tank to realize the oil cooling cycle.

[0004] During the oil cooling process, the absorbed oil contains a large amount of heat. When it flows back into the oil tank, the oil is still in a warm state, which is not conducive to the circulation and heat dissipation of the oil in the next device. At the same time, the heat dissipates inside the device, which will also cause a waste of resources.

[0005] Therefore, it is necessary to provide a screw air compressor with waste heat recovery function to solve the above problems. Utility Model Content
