The economical and practical 75HP two stage permanent magnet variable frequency air compressor with waste heat recovery is an efficient and energy-saving industrial equipment that combines two-stage compression, permanent magnet variable frequency technology, and waste heat recovery system. The air compressor adopts a permanent magnet synchronous motor, which has an energy efficiency improvement of about 10% -15% compared to ordinary asynchronous motors. It also achieves a 30% -100% gas volume adjustment range through an intelligent frequency conversion control system, reducing energy waste. Its dual stage compression design stabilizes the exhaust pressure between 0.8-1.2MPa, and is equipped with high-precision rotor teeth, resulting in an approximately 8% increase in volumetric efficiency compared to traditional designs. The waste heat recovery system recovers about 80% of the thermal energy generated during the operation of the air compressor through a heat exchanger (mainly present in the hot oil), and converts it into hot water at 45-65 ℃, which can be used for employee domestic water or process preheating. This technology not only solves the problem of high temperature in summer for air compressors, extends equipment life, but also significantly reduces operating costs for enterprises, achieving energy conservation and emission reduction.
