Abstract

This invention relates to coupling apparatus and method for desalting seawater by using nuclear energy. The apparatus comprises: a small-scale nuclear thermal reactor, a reverse osmosis seawater desalting system, a distillation seawater desalting system, and auxiliary apparatus. The method comprises: (1) transferring the heat generated from the small-scale nuclear thermal reactor to the steam generator, and driving the reverse osmosis high-pressure pump with the generated saturated steam in the turbine for seawater desalting; (2) introducing the saturated steam exhausted from the end stage of the turbine to the distillation seawater desalting system for seawater desalting; (3) returning the condensed water to the steam generator; (4) introducing seawater into the distillation seawater desalting system, cooling at the heat discharge section, sending to the reverse osmosis high-pressure pump, pressurizing, sending to the reverse osmosis seawater desalting system, storing the product water in a desalted water tank, and utilizing the condensed seawater or discharging into sea. The method has such advantages as advanced technology, high heat utility, high water productivity and high water quality.

Description

technical field [0001] The invention belongs to the technical field of nuclear energy application and seawater utilization, and in particular relates to a coupling method between a nuclear heating reactor and a seawater desalination system. Background technique [0002] Desalination of seawater using nuclear reactors as an energy source is an important field of nuclear energy applications. Many countries in the world have carried out research on the coupling technology of nuclear reactors and seawater desalination systems, and achieved many phased results. So far, Kazakhstan and Japan have established practical industrial-scale nuclear desalination plants, and India's nuclear desalination demonstration plant is under construction. These seawater desalination plants are all coupling seawater desalination technology with power generation nuclear reactors for cogeneration of electricity and water. Some countries in the world have also carried out technical research on the cou...
