DEVICE FOR THE PRODUCTION OF POTABLE WATER BY SOLAR MEANS FROM SEAWATER OR BRACKISH WATER

摘要

The invention relates to a device for the production of potable water by solar means from seawater or brackish water, comprising a housing (2), arranged at an angle, completely enclosed and thermally well-insulated. The front surface (13) thereof, facing the sun, is enclosed by a transparent sheet. An evaporation surface (3) is situated in the housing (2), dividing the interior of the housing into an upper evaporation chamber (4) and a lower condensation chamber (5). Said evaporation chamber (4) and condensation chamber (5) are connected at the lower end of the evaporating surface such that the air mass enclosed in the housing can circulate. A brine pan (6) is arranged at the lower end of the evaporation surface (3), which catches brine (14) dropping from the evaporation surface (3) and is equipped with an overflow (7). A potable water outlet (8) is arranged at the lower end of the condensation chamber (5), in which at least one first condenser (9) is arranged. According to the invention, a feed line (20), with integrated pump (21), goes from the brine pan (6) to the inlet of the at least one first condenser (9), a line (22) goes from the outlet of the at least one first condenser (9) to the upper end of the evaporation surface (3) and an inlet for the dosed feed of salty water (26) is connected to the brine pan (6).
