The invention provides a sea water desalination method and a sea water desalination device for portable marine rescue. The device comprises a water production module, an energy supply module, an automatic control module and an auxiliary module, wherein the water production module comprises a water intaking device, a pretreatment device, a sea water desalination device and a water storage device; the energy supply module comprises a solar panel and a storage battery; the automatic control module comprises a sensor, a PLC control board, a switch and an indicator light; the auxiliary modular comprises a buoyancy increase device, a draw bar and wheels. Sea water enters the pretreatment device through the water intaking device, enters the sea water desalination device for heating after being pretreated, and then enters a hydrophobic membrane element, wherein generated water vapor penetrates through the hydrophobic membrane element, fresh water is obtained after cooling and enters the water storage device. The sea
