Abstract：This paper first introduces the working characteristics and principle of the fuel injection screw air compressor, points out the theoretical use of the waste heat recovery in the air compressor, describes the air compressor waste heat utilization method and the equipment composition. Then, the available heat of each component of the air station is calculated and analyzed, and the theoretical calculation of the amount of heat available in the air compressor station is used to analyze the factors that affect the recoverable heat, such as exhaust temperature, fuel injection temperature and fuel injection and so on.

Taking into account the type of air compressor station, the environment of the application, this paper designed a plate heat exchanger to heat tap water, for the staff of domestic water, and by calculating the heat and pressure drop to check the design rationality of the heat exchanger; Designed air cooler and use high temperature lubricating oil to heat the air, the heated air makes the adsorber of the rotor dehumidifier regenerate.According to the parameters of the equipment selected centrifugal fans, pumps, water tanks, valves, etc., to form a complete operating system.

Finally, this paper calculates the recoverable heat and the investment cost, and points out the economic and environmental protection of waste heat recovery system design.

Key words: fuel injection screw air compressor station; waste heat recovery; plate heat exchanger; adsorbent regeneration
