A system for coupled cogeneration of nuclear power and low-temperature multi-effect seawater desalination

Abstract

The invention discloses a nuclear power and low temperature multi-effect sea water desalination coupling cogeneration system, belonging to the technical field of nuclear power utilization and low temperature multi-effect sea water desalination. The system comprises a small-sized nuclear reactor, a vapor generator, a turbine, a vapor converter, a vapor thermal compressor, a low temperature multi-effect evaporator and auxiliary equipment. In the system, the nuclear reactor provides energy so as to drive the vapor generator to generate high pressure vapor, the high pressure vapor enters the turbine and generates electricity through working, part of vapor is extracted out from the turbine to be offered to the vapor converter, the vapor converter heats up internal demineralized water through the heat of the vapor so as to generate secondary vapor, and the secondary vapor drives the vapor thermal compressor and the low temperature multi-effect sea water desalination system to generate fresh water. The system has the advantages that nuclear energy utilization is high in safety, the quality of generated fresh water is good, and electricity-water cogeneration is economic.

Description

technical field [0001] The invention relates to a coupled cogeneration system of nuclear power and low-temperature multi-effect seawater desalination, which belongs to the technical field of nuclear energy utilization and low-temperature multi-effect seawater desalination. Background technique [0002] Seawater desalination is an important way to solve the global freshwater crisis in the 21st century, but for now, it is still an energy-intensive industry. At present, the large-scale mature commercial seawater desalination process mainly includes multi-stage flash evaporation, multi-effect evaporation and reverse osmosis. Multi-stage flash evaporation and multi-effect evaporation need to consume a lot of heat energy and a small amount of electric energy, while the membrane method needs to consume more electric energy. Using traditional fossil fuels to generate heat and electricity for desalination of seawater will inevitably release a large amount of greenhouse gases and hav...
