Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, in particular to an air compressor waste heat recovery device with an impurity removal function. Background Art

[0002] The current working process of a screw air compressor is as follows: After passing through an intake filter to remove dust and impurities from the atmosphere, air enters the compressor through the intake control valve. During the compression process, it mixes with the injected cooling lubricant. The compressed mixed gas is discharged from the compression chamber into an oil-gas separator, resulting in high-temperature, high-pressure oil and gas, respectively. Due to the machine's operating temperature requirements, these high-temperature, high-pressure oil and gas must be fed into separate cooling systems. The compressed air is cooled by a cooler before being fed into the use system, while the high-temperature, high-pressure lubricant is cooled by a cooler before returning to the oil circuit for the next cycle. During this process, the heat carried by the high-temperature, high-pressure oil and gas is roughly equivalent to one-quarter of the air compressor's power, and its temperature is typically between 80°C and 100°C. While the screw air compressor can cool the high-temperature, high-pressure oil and gas through its own heat dissipation system, a large amount of heat energy is wasted in the process.

[0003] Chinese utility model patent publication number CN 204646669U discloses an air compressor device with heat recovery. The device includes a high-temperature oil delivery pipe that passes through a waste heat recovery unit and then connects to a low-temperature oil connecting pipe. The low-temperature oil connecting pipe is connected to a three-way valve at its end. The other ends of the three-way valve are connected to the air compressor and oil cooler, respectively. The three-way valve is equipped with a switch that allows one of the ends connecting the air compressor and oil cooler to be opened. The waste heat recovery unit is equipped with a waste heat recovery pipe. The waste heat recovery pipe includes a water inlet and a water outlet. Water enters through the water inlet and flows out through the water outlet. The main portion of the waste heat recovery pipe is located in the waste heat recovery unit and is adjacent to the wall of the high-temperature oil delivery pipe. This device has the advantages of cooling the high-temperature oil in the air compressor while recovering waste heat from the oil and further cooling the recovered hot oil.

[0004] The belt tension adjustment in the above-mentioned public documents cannot discharge heat from the integrated air compressor to remove impurities during the waste heat recovery process, so there is a need for an air compressor waste heat recovery device with a impurity removal function.
