Solar thermoacoustic rotary power generator

Abstract

The invention relates to a solar thermoacoustic rotary power generator, which comprises a heat collecting cavity used for collecting solar energy collected on a condensing reflecting plane, a thermoacoustic engine used for converting the solar energy into sound wave energy in order to convert the alternating flow of oscillating current into the rotary power for output, and a rotary generator used for generating power by the energy output by the rotary power, wherein the thermoacoustic engine comprises a self-rectifying air turbine device used for converting the alternating flow of the oscillating current into the rotary motion. The solar thermoacoustic rotary power generator drives the thermoacoustic engine with the self-rectifying air turbine device by collecting the solar energy, converts the alternating flow of the oscillating current into the rotary motion to drive the rotary type generator to work and has small abrasion, high efficiency, good controllability and other excellent properties and wide applicability.

Description

technical field [0001] The invention relates to a thermoacoustic power generation system, in particular to a solar thermoacoustic rotary power generator. Background technique [0002] In the prior art, there are two ways to convert the alternating flow generated by the thermoacoustic engine into rotary motion to drive the generator to generate electricity. One is to use the piston to push the connecting rod mechanism. Such as figure 1 As shown, it is a structural schematic diagram of an existing thermoacoustic engine. Heat is added to the hot-end heat exchanger 1, and a temperature gradient is formed on the hot-end heat exchanger 1 and the cold-end heat exchanger 3 on both sides of the plate stack 2; when the temperature When the gradient exceeds the critical temperature gradient, the system starts to work, generating a pressure wave; driven by the pressure wave, the piston 51 in the resonant tube 4 reciprocates, and the crankshaft 53 is driven to rotate through the connect...
