Abstract

The invention relates to a medium-and-low temperature heat recovery technology, and provides an ORC compressed air preparation device and method. The device comprises an evaporator, a secondary heat exchanger, a turbine coaxial integrated machine, a condenser and a working medium pump. The turbine coaxial integrated machine is formed by coaxially and directly connecting a turbine expander with a turbine compressor, the turbine expander is used for doing work by expansion, and the turbine compressor is used for preparing compressed air. All the devices are connected through pipelines. The outlet end of the working medium pump is connected with a working medium inlet of the evaporator, and a working medium outlet of the evaporator is connected to a working medium inlet of the turbine expander through the secondary heat exchanger. A working medium outlet of the turbine expander is connected to the inlet end of the working medium pump through the condenser. A compressed air outlet of the turbine compressor is connected to a compressed air inlet of the secondary heat exchanger. Medium-and-low temperature waste heat recovery is achieved through ORC, the compressed air is directly prepared, the inlet temperature and pressure of the expander are increased through compression heat recovery, and the recovery efficiency of waste heat energy is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medium and low temperature waste heat recovery and utilization, in particular to an ORC device and method for producing compressed air. Background technique [0002] In iron and steel, non-ferrous metals, petrochemical, building materials, light industry and many other industries, production enterprises have a large amount of low-grade waste heat, including flue gas, steam and hot water, which are low in grade, large in quantity, and scattered, and basically cannot be used for Production reuse. Under the background of the current policy of energy saving and emission reduction, waste heat utilization technology has attracted more and more attention from the industry and academia. The promotion of medium and low temperature waste heat power generation or the recovery of medium and low temperature waste heat to produce compressed air is an important way to utilize low-grade waste heat. . [0003] At presen...
