Abstract

The invention relates to the technical field of thermal energy power generation and discloses a supercritical carbon dioxide circulating system. The system comprises a compressing module, a heat source module, a turbine power generation module and a cooling module which are connected sequentially. The system further comprises a constant-temperature and constant-pressure module. The cooling moduleis connected with the compressing module through the constant-temperature and constant-pressure module. The constant-temperature and constant-pressure module comprises a constant-temperature chamber and a pressure stabilizing channel arranged in the manner of penetrating through the constant-temperature chamber. A heat exchange fin is arranged on the outer side wall face of the pressure stabilizing channel. The heat exchange fin is located in the constant-temperature chamber. The pressure stabilizing channel is filled with multiple damping balls. A circulating working medium outlet of the cooling module is connected with a circulating working medium inlet of the compressing module through the pressure stabilizing channel. According to the supercritical carbon dioxide circulating system, the constant-temperature and constant-pressure module replaces a large-capacity buffering tank, temperature and pressure fluctuation of circulating working media in the ocean jolting environment is reduced, and the ability of the circulating working media to maintain constant-temperature and constant-pressure parameters at an inlet of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a supercritical carbon dioxide circulation system. Background technique [0002] With the gradual deepening of my country's marine development, the development of advanced marine equipment is imperative, and the power system is the "heart" of marine equipment such as ships, and is the key to determining the overall performance of ships. Supercritical carbon dioxide (S-CO 2 ) Brayton cycle, as an emerging power system, has significant advantages such as compact structure, high efficiency, small size, light weight, and low noise, and is an ideal choice for ship power systems. [0003] S-CO 2 cycle is a CO in a supercritical state 2 Brayton cycle as working fluid, compressor as S-CO 2 The main prime mover in the cycle is the core equipment for maintaining efficient and stable operation of the cycle. Due to S-CO 2 It has excellent compressibility near the criti...
