Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat recovery of air compressors, in particular to a heat recovery pipeline device for a screw air compressor. Background Art
[0002] Screw air compressors are pre-assembled screw-type air compressors that only require a single power connection and compressed air connection, and have a built-in cooling system. Screw air compressors have the advantages of high performance, high efficiency, and maintenance-free. During operation, screw air compressors generate a large amount of heat, which is discharged into the air through air cooling or water cooling, resulting in energy waste. By recovering the heat generated by the air compressor, this "excess" heat can be utilized to reduce energy consumption and achieve the effect of energy conservation and emission reduction.
[0003] An existing heat recovery mechanism for a screw air compressor (Announcement No.: CN220748531U) transfers the heat generated during the operation of the screw air compressor body to the water in the heat exchange box through a heat conduction plate, a heat conduction sheet, and a heat conduction block. A temperature monitor monitors the water temperature in the heat exchange box. Although the water in the heat exchange box can be stirred by a stirring rod to increase the contact area between the water and the heat conduction sheet, the heat conduction sheet still cannot fully contact the water during the heat conduction process, resulting in less than ideal heat transfer to the water, which in turn affects the heat recovery efficiency of the air compressor.
