Organic Rankine cycle power generation system based on gas-liquid separation and double-level evaporation

Abstract

The invention provides an organic Rankine cycle power generation system based on gas-liquid separation and double-level evaporation. The organic Rankine cycle power generation system comprises an organic Rankine cycle power generation system body and a gas-liquid separator system; the gas-liquid separator system comprises a first heat exchanger, a second heat exchanger, a condenser, a first pump,a second pump and a gas-liquid separator; the first pump is in close-loop connection with the first heat exchanger, the gas-liquid separator, the second pump, the second heat exchanger, the organic Rankine cycle power generation system body and the condenser in sequence through a pipe; a gas outlet of the gas-liquid separator is connected with the input end of another organic Rankine cycle power generation system body, and the output end of another organic Rankine cycle power generation system body is connected with the condenser; the pipe is filled and mixed with an organic working medium. The mixing concentration of the mixing worked medium can be changed, even if heat source temperature of working medium of the working medium changes, the system optimal heat efficiency matched with theheat source temperature can be obtained, and thus the utilization rate of energy is increased.

Description

technical field [0001] The invention relates to the field of thermal power generation, in particular to an organic Rankine cycle power generation system based on gas-liquid separation and double-stage evaporation. Background technique [0002] Energy shortage and environmental pollution have become major problems restricting the development of the world economy, and improving energy utilization efficiency and developing new energy have become important measures to solve this problem. [0003] At present, energy mainly comes from oil, natural gas, coal, etc. These energy sources are on the verge of exhaustion, and have also caused serious environmental pollution. As we all know, sulfur dioxide emitted from burning fossil fuels is the main cause of acid rain, and carbon dioxide emitted is the main cause of global warming. Therefore, finding a cheap, renewable energy source that does not cause environmental pollution is the only choice that human beings must face. [0004] Am...

Problems solved by technology

In practical applications, because the generated industrial waste heat is unstable and fluctuating, that is, the temperature of the heat source is easy to change, but at the same time, the optimal heat source temperature corresponding to each working fluid is not the same, so when the temperature of the heat source changes, it cannot Satisfied that the system operates within the working condition of the best thermal efficiency
