ORC (organic Rankine cycle) system for recycling waste heat of electric generator

Abstract

The invention relates to an ORC (organic Rankine cycle) system for recycling waste heat of an electric generator. The ORC system comprises a working medium circulating system connected with the electric generator, and further comprises an electric generator waste heat recovery system and a steam jet cooling system, the electric generator waste heat recovery system is configured for distributing aworking medium in the working medium circulating system and introducing the working medium into the electric generator to absorb the waste heat produced during working of the electric generator; and the steam jet cooling system is configured for boosting the working medium absorbing the waste heat of the electric generator, carrying out jet cooling and decompression, sucking the gaseous working medium in the working medium circulating system and reducing condensing temperature of the ORC system. According to the ORC system, the working medium is not required to be increased, besides, the structure is simple, no moving parts are arranged, the waste heat of the electric generator is recycled, the output power of an expansion machine is increased, and the energy utilization efficiency of thewhole system is improved.

Description

technical field [0001] The invention relates to the field of low-temperature waste heat power generation systems, and more particularly relates to an ORC system for recovering and utilizing waste heat of a generator. Background technique [0002] With the gradual depletion of primary energy, people pay more and more attention to the utilization of low-grade heat energy such as solar energy, geothermal heat, and factory waste heat. Reducing energy consumption, saving energy and reducing emissions, and improving energy utilization are the fundamental ways to solve the problem of energy shortage. The Organic Rankine Cycle (ORC) system can convert low-grade thermal energy into high-grade electrical energy, which can improve the comprehensive utilization rate of energy. [0003] The ORC system completes the entire cycle through low-boiling organic working fluid, which is mainly composed of evaporators, expanders, generators, condensers, working fluid pumps and other equipment.
