Air compressor oil circuit circulation device

The invention relates to heat recovery, and particularly to an air compressor oil circuit circulation device. The air compressor oil circuit circulation device comprises an oil-gas separator, whereinthe oil-gas separator forms a circulation loop with an oil pump, a three-way temperature control valve and an air-compressor set; the three-way temperature control valve is connected with a cooler inlet; a cooler outlet is connected with a pipe between the three-way temperature control valve and the air-compressor set; and a coiled-cooling pipe is wound at the bottom of the oil-gas separator. Theair compressor oil circuit circulation device has the benefits as follows: the working temperature of the air compressor is effectively reduced, the failure occurrence probability of the machine is reduced, the service life of the equipment is prolonged, heat generated by the air compressor during working is fully utilized, the structure is simple, the oil heat recovery utilization rate is high after two-stage cooling, and
