Description
technical field [0001] The invention relates to a seawater desalination device and a seawater desalination method using the seawater device, in particular to a seawater desalination device using centrifugal fogging technology and solar energy. Background technique [0002] At present, there are dozens of seawater desalination technologies. The main industrial applications include reverse osmosis, multi-stage flash evaporation, and multi-effect evaporation. Multi-stage flash seawater desalination is to evaporate the heated seawater in a plurality of flash chambers where the pressure is gradually reduced, and condense the steam to obtain fresh water. Reverse osmosis is a desalination technology that pressurizes seawater to make fresh water pass through a semi-permeable membrane. Multi-effect evaporation is to evaporate heated seawater in multiple evaporators in series, and the steam evaporated from the previous evaporator is used as the next evaporator. The heat source ...
