Optimization of SCO₂ Brayton Cycle Coupled Seawater Desalination System

超临界二氧化碳布雷顿循环由于其紧凑的系统布置和较高的热电转换效率,是非常有前景的新型核动力系统热电转换装置的技术方案。在传统的布雷顿循环中,超临界二氧化碳在进入压缩机前需要冷却,因此在系统中存在废热。本文研究用于小型铅冷快堆的能量转换系统,将海水淡化装置与超临界二氧化碳布雷顿循环耦合,进行废热利用,扩展能量转换系统的多用途应用方向,实现淡水生产,提高系统总体的效率。

Supercritical carbon dioxide Brayton cycle is a promising technical scheme for the thermoelectric conversion device of new nuclear power system due to its compact system layout and high thermoelectric conversion efficiency. In the traditional Brayton cycle, supercritical carbon dioxide needs to be cooled before entering the compressor, so there is waste heat in the system. In this paper, the energy conversion system for small lead-cooled fast reactor is studied. The seawater desalination device is coupled with the SCO2 Brayton cycle to carry out waste heat utilization, expand the multi-purpose application direction of the energy conversion system, realize freshwater production, and improve the overall efficiency of the system.
