Abstract

The invention relates to a solar constant pressure heating hot airflow engine generation system which comprises a double-shaft tracking solar focusing reflector surface system, a solar constant pressure heating power conversion unit (i.e. a hot airflow engine) and a generator, and is characterized in that: the solar constant pressure heating power conversion unit comprises an air compressor, an air storage tank, a solar energy absorber and an output shaft power cylinder component; the output shaft power cylinder component comprises a cylinder, a piston, a connecting rod and a crank; an air inlet and an exhaust port which are arranged on the cylinder, an air inlet valve which is arranged on the air inlet, an exhaust valve which is arranged on the exhaust port, the air compressor, the air storage tank and the solar energy absorber are sequentially and serially connected by an air transmission pipe and then are connected with the air inlet; the piston is connected with the crank through the connecting rod; ; and a crank shaft is coupled with the generator. The solar constant pressure heating hot airflow engine generation system has the advantages that: the air serves as a working substance, no water needs to serve as the working substance, no tower tube (or chimney) is needed, a huge radiating mechanism of a Stirling engine is cancelled, the cost is low, the generation efficiencyis high and the stability is good.

Description

technical field [0001] The invention relates to a solar energy constant pressure heating hot air flow engine power generation system, which belongs to the field of solar thermal power generation. Background technique [0002] Solar thermal power generation and solar photovoltaic power generation are two different types of power generation methods for solar power generation. Solar thermal power generation mainly includes tower type, trough type, dish type, strip type, tower tube thermal airflow power generation and other methods. [0003] Tower, trough and strip solar thermal power generation requires water as a working medium, and tower (chimney) hot air solar power generation requires a very high tower (chimney). [0004] Disc (or disc) solar power generation does not require a tower or water as a working medium. Disc power generation uses a Stirling cycle. Since the working medium does not require water, the solar disc Stirling engine is also called For a hot gas engine,...
