Abstract

The invention discloses an ORC pressurization and energy-saving air compressor. The air compressor comprises an evaporator, a rear-end heat exchanger, a turbo expander, a condenser, a liquid working medium pump, a pre-heat exchanger, a preceding-stage air compressor and a two-stage air compressor. According to the air compressor, heat of hot air generated by one-stage compression of the air compressor is recycled through ORC circulation; driving power generated in the ORC circulation drives the turbo expander-compressor to compress primarily cooled air after one-stage compression, and therefore the purpose of pressurization is achieved; the air after pressurization exchanges heat with an organic working medium of the ORC circulation twice so as to achieve the purpose of cooling; and the whole air compressor is ingenious in structure, air compression waste heat is fully utilized, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to an air compressor, in particular to an ORC supercharging and energy-saving air compressor. Background technique [0002] Organic Rankine Cycle (ORC for short) is a Rankine cycle that uses low-boiling point organic substances as working fluids. It is mainly composed of waste heat boiler (or heat exchanger), turbine, condenser and working fluid pump. The organic working medium absorbs heat from the waste heat flow in the heat exchanger to generate steam with a certain pressure and temperature, and the steam enters the turbomachine to expand and do work, thereby driving the generator or dragging other power machinery. The steam discharged from the turbine releases heat to the cooling water in the condenser, condenses into a liquid state, and finally returns to the heat exchanger with the help of the working medium pump, and the cycle continues in this way. [0003] At present, domestic ORC is only used in geothermal power genera...
