Abstract
A water purification and/or desalination plant for producing drinking water from a polluted water source or sea water with the aid of sunlight, which plant includes an evaporator (1) having a roof part (2) made of a light-penetrable material, and an underlying basin part (3) containing the water that is to be purified, which basin part (3) includes channels (17) for collecting water vapor that has been condensed on the inside of the roof part (2), and a reservoir (10) for purified water. The plant also includes a device for removing moist air or vapor from the evaporator and a device for condensation of the moist air or vapor outside the evaporator.
Claims7
A water purification and/or desalination plant for producing drinking water from a polluted water source or sea water with the aid of sunlight comprising:
- an evaporator unit (1) having a roof part (2) consisting of a light-penetrable material
- an underlying basin part (3) containing water (12) that is to be purified;
- which basin part (3) includes means (17) for collecting water that has been condensed on the inside of the roof part (2) and a reservoir (10) for purified water unit, means for removing moist air or vapor from the evaporator, and means for condensing the moist air or vapor outside the evaporator unit;
- wherein the basin part (3) further includes means for increasing the absorption of heat, said means for increasing the absorption of heat comprising a plate-shaped body (14) and buoyancy bodies or floats (15) which maintain the plate-shaped body a constant distance from a surface (13) of the water (12) in the basin part;
- which plate-shaped body has a dark, heat-absorbent surface and includes a thermal insulation material.
