Abstract

The utility model discloses an air-exhausting-then-hot-ejection type organic Rankine cycle (ORC) system comprising a working medium pump, a heat exchanger, an expansion machine, a condenser and an ejector, wherein the working medium pump, the heat exchanger, the expansion machine, the condenser and the ejector are sequentially connected, the expansion machine is provided with an air exhausting pipe, a heat exchange pipe connected with the air exhausting pipe is arranged in the heat exchanger, and a working medium outlet of the heat exchange pipe communicated with the air exhausting pipe is communicated with an ejection airflow inlet of the ejector. An inner cavity of the expansion machine or an outlet working medium of the expansion machine passes through the heat exchanger and is led to the ejector to serve as ejection airflow through the air-exhausting pipe, after the organic working medium absorbs thermal energy of a low-grade heat source, pressure is increased, the temperature is increased, ejection effects are good, force of the expansion machine can be increased, work ability of the organic working medium is improved, and output of power is increased. Meanwhile, the ejection working medium absorbs the low-grade heat source thermal energy in the heat exchanger, and the recycle rate of low-grade heat source thermal energy is improved. Therefore, the system is greatly improved in waste heat recycle efficiency and efficient power outlet rate, and technical breakthroughs are made.
