NOVELTY - The solar membrane distillation sea water desalting device comprises a hollow fiber membrane assembly (4), a filter (3), a raw water pump (1), a solar heater (5), a solar energy thermoelectric system (2), a water tank (6), and a connecting pipeline. The raw water pump is connected with an inlet of the filter. The filter is connected with a cold sea water inlet of the membrane assembly. A water outlet of the solar water heater is connected with a water inlet of the solar water heater. The solar water heater is connected with the membrane component.    USE - Used as a solar membrane distillation sea water desalting device.    ADVANTAGE - The solar membrane distillation sea water desalting device has simple structure, and high heat recovery rate, and does not need power during desalination of sea water.    DETAILED DESCRIPTION - The solar membrane distillation sea water desalting device comprises a hollow fiber membrane assembly (4), a filter (3), a raw water pump (1), a solar heater (5), a solar energy thermoelectric system (2), a water tank (6), and a connecting pipeline. The raw water pump is connected with an inlet of the filter. The filter is connected with a cold sea water inlet of the membrane assembly. A water outlet of the solar water heater is connected with a water inlet of the solar water heater. The solar water heater is connected with the membrane component. A hot sea water inlet of the membrane assembly is connected with a water tank. The membrane assembly is provided a hot sea water inlet, a hot water outlet, a sea water cooling inlet, a cold water outlet, an exhaust port and a water inlet. The hollow fiber membrane assembly has sheet-shaped curtain. The membrane assembly has an outer diameter of 2-2.5 mm, an inner diameter of 0.6-1.5 mm, an average aperture of 0.05-0.5 mu m, a porosity factor of 50-85% and a length of 0.6-1.5 m. The raw water pump is corrosion resistant water pump or water-gas mixing pump.
