Waste Heat Recovery For Screw Compressors
Screw compressor is a kind of compressor equipment which is widely used in the industrial field. It compresses the gas through the rotary movement of the screw and produces high pressure gas. In this process, the screw compressor generates a large amount of waste heat. Through the waste heat recovery technology, these waste heat can be effectively utilised to improve the efficiency of energy utilisation.
A common way to recover waste heat from screw air compressors is to use heat exchangers or heat pipe heat exchangers. The specific working principles are as follows:
Waste heat recovery system: During the working process of screw air compressor, the waste heat generated is collected and recovered through the waste heat recovery system. This system usually consists of a heat exchanger or heat pipe heat exchanger, a cooling medium (e.g. water or lubricating oil) and a pipework connection system.
Heat exchanger or heat pipe heat exchanger: The waste heat is exchanged with the cooling medium through a heat exchanger or heat pipe heat exchanger. During the heat transfer process, the thermal energy of the waste heat is transferred to the cooling medium, raising its temperature.
Utilisation of the cooling medium: The cooled medium after the heat exchange can be used for other energy requirements, e.g. for heating water, heating systems, processes etc. By utilising the cooling medium from waste heat recovery, the consumption of other energy sources can be reduced and the efficiency of energy use can be improved.
The advantages of waste heat recovery for screw air compressors include:
Energy saving: by recycling waste heat, the demand for other energy sources can be reduced, reducing energy consumption and achieving energy saving.
Environmentally friendly: Waste heat recovery reduces the emission of waste heat, reducing the negative impact on the environment and helping to reduce greenhouse gas emissions.
Economic benefits: By improving energy use efficiency and reducing energy consumption, screw air compressor waste heat recovery can bring economic benefits and cost savings.
