Abstract

The invention belongs to the technical field of energy and power, in particular to a Stirling heat regenerator-organic Rankine cycle system and a use method thereof. According to the Stirling heat regenerator-organic Rankine cycle system, a working medium liquid storage tank, a working medium pump, a Stirling cold-cavity heat exchanger, a working medium evaporator, a thermal power conversion device, a Stirling thermal-cavity heat exchanger, a working medium condenser and a working medium liquid storage tank are connected in sequence to form a circulation loop; the Stirling cold-cavity heat exchanger and Stirling thermal-cavity heat exchanger are respectively connected with a Stirling engine; each of the thermal power conversion device and Stirling engine is connected with a corresponding generator. The Stirling heat regenerator-organic Rankine cycle system fully combines the existing organic Rankine cycle technology with the Stirling engine, steam exhaust from the outlet of the thermal power conversion device is converted into high-quality electric energy through the Stirling engine, the heat is transmitted to low-temperature working medium at the outlet of the working medium pump in the process to serve as the heat regenerator of the system, the thermal efficiency of the system is improved, and energy saving and consumption reducing are realized.

Description

technical field [0001] The invention belongs to the technical field of energy and power, and in particular relates to a Stirling machine regenerator-organic Rankine cycle system and a using method thereof. Background technique [0002] The Stirling engine was invented in 1816 by Robert Stirling, a pastor in London, so it was named "Stirling engine". Stirling engines are unique heat engines in that their practical efficiency is nearly equal to the theoretical maximum efficiency, known as the Carnot cycle efficiency. The Stirling engine generates power by expanding the gas when it is heated and compressing it when it is cooled. This is an external combustion engine that burns the fuel continuously, the evaporated expanded hydrogen (or helium) is used as the power gas to move the piston, and the expanded gas is cooled in the cold air chamber, and this cycle process is repeated. Stirling machine is accompanied by endothermic and exothermic process in the process of pushing the...
