Description

technical field [0001] The invention relates to the field of air compressor waste heat recovery, in particular to an air-cooled air compressor waste heat recovery system and control method. Background technique [0002] The air compressor is a common power equipment, which is a device that converts mechanical energy into gas pressure energy. Simply speaking, it is a pressure generating device for compressing air. The main function of the air compressor is to supply air and provide the gas required for production. [0003] Air compressors are widely used in my country, especially the market share of air-cooled air compressors is particularly prominent. For example, air-cooled air compressors are used in biochemical projects, waste power plant projects and gas turbine projects. Among them, in the existing large and medium-sized projects, The waste heat sampling and heat exchange centralized processing and distribution of air-cooled air compressors requires a complete set of ven...

[0003] Air compressors are widely used in my country, especially the market share of air-cooled air compressors is particularly prominent. For example, air-cooled air compressors are used in biochemical projects, waste power plant projects and gas turbine projects. Among them, in the existing large and medium-sized projects, The waste heat sampling and heat exchange centralized processing and distribution of air-cooled air compressors requires a complete set of ventilation and air-conditioning systems, which are expensive. Among them, the existing air-cooled air compressors for small and medium-sized projects directly suck air from the room, and the wind sucked by mechanical energy is followed by The fluidity of the air carries the heat out of the room, so that the working environment of the air compressor can be kept within a suitable working range. If the factory is located in a severe cold area, when heating facilities need to be installed in winter, it is necessary to build heating facilities in the air compressor workshop, such as ventilation Air conditioners, radiators, etc., as well as the existing air-cooled air compressor waste heat recovery system, the control system is not highly automated, and the control process is not perfect. Therefore, the existing heat energy is not used, resulting in human resources, capital costs and resources. waste
