Air compressor waste heat recycling device

The utility model discloses an air compressor waste heat recycling device. The device comprises an air compressor system composed of an air compressor, an oil-gas separator, a bypass-valve, an oil cooler, an air cooler and an oil filter, and further comprises an oil path electric valve, a heat transfer module, a gas path electric valve, a heat transfer enhancement module, an energy storage module and a heat energy utilization module. The oil path electric valve is arranged between an oil outlet of the oil-gas separator and the bypass-valve, the heat transfer module is connected with the oil path electric valve in parallel, the gas path electric valve is arranged between a gas outlet of the oil-gas separator and the air cooler, the heat transfer enhancement module is connected with the gas path electric path in parallel, the energy storage module is connected with the heat transfer module and the heat transfer enhancement module, and the heat energy utilization module is matched with the energy storage module. According to the air compressor waste heat recycling device, the heat transfer module and the heat transfer enhancement module are used for recycling and storing heat energy in cycle oil and heat energy in compressed air respectively, wherein the heat energy is lost and wasted when the air compressor runs; the heat transfer way can be controlled according to actual conditions of the air compressor, and waste heat utilization efficiency can be improved to the largest degree on the premise that normal work of the air compressor system is ensured.
