System and method for supplying energy and storing energy by utilizing waste heat of air compressor

Abstract

The invention relates to a system and a method for supplying energy and storing energy by utilizing waste heat of an air compressor. The air compressor commonly adopts cooling coil for bringing out and directly introducing heat generated by a machine into air, and causes heat pollution on environment. The system is characterized in that a cooling oil outlet of the air compressor is connected to an oil side inlet of an oil-water heat exchanger through a cooling oil outlet tube of the air compressor, wherein a water side outlet of the oil-water heat exchanger is connected to a heat source inlet of a generator through a closed type circulating water outlet tube; a heat source outlet of the generator is connected to a water side inlet of the oil-water heat exchanger through a closed type circulating water inlet tube; a refrigerant steam outlet of the generator is connected to a refrigerant steam inlet of a condenser through a condensing steam pipeline; a thin solution outlet of an absorber is connected to a solution inlet of the generator through a thin solution pipeline; and a thick solution inlet of the absorber is connected to a thick solution outlet of the generator through a thick solution pipeline. By virtue of the system, waste heat utilization range of the air compressor is wider, and heating and refrigerating performances are better.

Description

technical field [0001] The invention relates to a system and method for energy supply and storage by using waste heat of an air compressor, which is a system capable of supplying cold energy and heat energy and can store energy, and belongs to the technical field of waste heat utilization. Background technique [0002] During the operation of the air compressor, due to the need to cool the high-pressure air, a large amount of medium and low temperature waste heat will be generated. At the same time, the internal rotating mechanism of the air compressor will also generate friction and heat, which needs to be cooled in time. This situation widely exists in centrifugal, screw Type and other types of air compressor units. Air compressors generally use cooling oil to take out the heat generated by the machine, and directly enter the air for cooling, which not only wastes heat, but also causes thermal pollution to the environment. With the gradual increase of our country's requir...

Problems solved by technology

Although this waste heat utilization method is simple, there are still many shortcomings, such as the inability to convert the waste heat into different forms of energy, the inability to effectively store the discharged waste heat, and the inability to realize the working condition that the heating capacity is higher than the waste heat.
