10. based on the desalination method of bar shaped mirror surface collection thermoelectric described in claim 1 energy supply microwave heating desalination plant,
It is characterized in that, comprising:
Light gathering reflector to cogeneration absorber is carried out photovoltaic power generation by several bar shaped specular reflective mirrors；
Photovoltaic power generation reaches the operating voltage of microwave heating steam and pressure stabilizing energy storage device after inversion and boosting and provides electricity
Energy；
Thermal energy caused by cogeneration absorber is heated into superheated steam to pure water during photovoltaic power generation；
Superheated steam boosts to steam heat temperature raising by microwave heating steam and pressure stabilizing energy storage device, stores up into air accumulator pressure stabilizing
Can, reverse osmosis pressure needed for being suitable for different salinity seawater is matched by control valve；
When the steam in steam drive seawater boost device reaches certain pressure, Steam Actuation gas drive liquid piston is to compress sea
Water enters reverse osmosis seawater desalting and pressure energy recyclable device generation fresh water and strong brine by pressurized seawater and is pressed
