RU2020109747A - METHOD AND PLANT FOR ROUND-THE-CLOCK SEA WATER DESALINATION - Google Patents

Claims (2)

1. A method for round-the-clock desalination of seawater using solar energy, including the following processes, namely, heating water, evaporating it, superheating steam, decomposing superheated steam into hydrogen and oxygen, accumulating and storing these gases, burning hydrogen in oxygen, obtaining molten salt in as a heat accumulator for desalination of sea water at night, cooling of salt melt and unloading of salt, condensation of water vapor, generation of electricity, characterized in that the accumulated hydrogen is divided into two streams before it is burned in oxygen, one of which is first used to generate electricity, after which these two streams of hydrogen are mixed with each other. 2. Installation of round-the-clock seawater desalination, designed to implement the method according to claim 1, containing a solar battery, an electric power accumulator with a transformer, a water intake pump, a storage tank for water, a hydro turbine, a water heating unit, a water evaporation unit, a steam superheating unit, a unit decomposition of water vapor into hydrogen and oxygen, a unit for condensation of water vapor, a tank for collecting condensate, a steam turbine with an electric generator, units for accumulation and storage of hydrogen and oxygen, a unit for burning hydrogen in oxygen, a unit for flash water evaporation, a unit for obtaining a salt melt and storing it in as a source of thermal energy, a salt melt cooling unit and salt unloading, characterized in that between the hydrogen storage and storage unit and the unit for its combustion in oxygen there are a unit for using part of the hydrogen to generate electricity and a unit for mixing and equalizing the pressures of two hydrogen streams: one supplied direct directly from the block of its accumulation and storage and another, coming from the block of its use for generating electricity.
