Solar disc-type air turbine power generation system

Abstract

The invention relates to a solar disc-type air turbine power generation system, which comprises a double-shaft tracking solar disc-type focusing reflection mirror surface system, an air compressor, a solar absorber, an air turbine and a generator, and is characterized in that one end of the solar absorber is connected with the air compressor; the other end is connected with the air turbine; an air turbine shaft is connected with a generator shaft; a thermal power cycle adopts an ideal turbine motor constant pressure heating cycle; air is used as a working medium; the air passes the air compressor to generate high-pressure air to be provided for the solar absorber; the solar absorber absorbs solar energy to complete the constant pressure heating; the high-pressure air is supplied for the air turbine to produce mechanical energy which is used for driving the generator to generate electric energy. The solar disc-type air turbine power generation system has the advantages that the working medium is air, no hydrogen and water are used as the working medium, the solar constant pressure heating cycle mode is adopted, and the air turbine is longer in service life than a piston type generator, small in vibration, simple in lubrication, higher in rotation speed, and smaller is size; as the air is adopted as the working medium, the water resource lack restriction of a desert photo-thermal CSP (concentrating solar power) power station does not exist.

Description

technical field [0001] The invention relates to a solar dish type air turbine power generation system, which belongs to the field of solar thermal power generation. Background technique [0002] Based on the study of the global energy situation, the International Renewable Energy Agency (IRENA) published a work report "Doubling the Proportion of Renewable Energy: Roadmap for 2030" in January 2014. The report pointed out that under the premise of strengthening global regional cooperation, by 2030 , the proportion of renewable energy can be doubled; under the influence of existing national renewable energy plans, there will be significant differences in the proportion of global renewable energy between different countries, improving energy efficiency and increasing broad access to energy will bridge this difference. IRENA defines traditional biomass energy as: in the residential sector, the energy used for cooking and heating using wood, charcoal, agricultural waste and anima...
