Nuclear thermoacoustic power generation system

Abstract

The invention relates to the technical field of thermoacoustic power generation and high-temperature gas-cooled reactors, and discloses a nuclear thermoacoustic power generation system, comprising a reactor core, a regenerator, a cold-end heat exchanger, a phaser, a linear motor, and a phaser. It includes a phase adjustment cylinder and a phase adjustment piston arranged in the phase adjustment cylinder; the gas flow channel in the reactor core is connected to one end of the phase adjustment cylinder to form an expansion chamber; the other end of the phase adjustment cylinder, the cylinder body of the linear motor and the The inlets of the gas heat exchange side of the cold end heat exchanger are connected to each other to form a compression cavity; the outlet of the gas heat exchange side of the cold end heat exchanger, the regenerator and the gas flow channel in the reactor core are connected in sequence; the reactor The reactor core and the phase modulator are arranged at intervals, and shielding layers are arranged between the reactor core and the phase modulator, and outside the reactor core, the expansion chamber, the regenerator and the cold end heat exchanger. The nuclear thermothermoacoustic power generation system has the advantages of long service life and compact structure, and can realize a portable nuclear power supply ranging from 100 kilowatts to megawatts.

Description

technical field [0001] The invention relates to the technical field of thermoacoustic power generation and high temperature gas-cooled reactors, in particular to a nuclear thermoacoustic power generation system. Background technique [0002] The compact thermoacoustic power generation system has the advantages of high efficiency, high reliability, long life, maintenance-free, mute, high specific volume power in the power generation range of MW level and below, and has unique advantages in the development of mobile and distributed power technology. . It has great application potential in underwater and space power, solar power generation, and household cogeneration. Thermoacoustic power generation is based on the generation and maintenance of acoustic oscillations by a compressible working medium under the action of a temperature gradient, thereby promoting the final conversion of acoustoelectric transducers into electrical energy. [0003] The thermal energy of the thermoa...
