▎ 摘　　要

NOVELTY - Portable self-driven solar desalination device comprises an evaporator (1), a condenser pipe (2), a condenser (3), a pontoon (4), an exhaust valve (5), a graphene foam panel, an evaporation tank, a water outlet, a condensing tank, a purified water collection tank, a bottom panel, a radiating fin and a water intake. A hydrophilic layer, a reverse dialysis layer and a photo-thermal conversion layer are combined. The graphene foam panel, the water outlet and the transparent flexible collapsible evaporation tank are combined into an evaporator. The condensing tank, the purified water collection tank, the bottom panel, the radiating fin and the water intake port are combined into a heat dissipating flexible foldable film condenser pipe. The condenser pipe is a transparent heat dissipation flexible foldable film tube, connects the upper tank port of the graphene foam panel of the evaporator with the upper tank port of the condensing tank of the condenser. USE - The device is useful in South China Sea island (claimed). ADVANTAGE - The device is convenient to carry and economical; and has simple structure, quick assembly and disassembly and self-driving effect. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the portable self-driven solar desalination device.
