Problems solved by technology

This structure is very complex
In addition, due to the hanging arrangement of the film bag, only small size bags can be manufactured, because otherwise the weight of the water to be purified would be too heavy and the film bag would become leaky or even rupture
In addition, the film bag must be emptied and removed of residue periodically, so this unit is only suitable for short-duration applications

Embodiment Construction

[0032] According to FIG. 1 , the evaporation container 1 according to the invention containing the water to be purified is arranged under a roof 6 which can be penetrated by the rays of the sun 4 . At least a part of the evaporation vessel 1 is formed by a laminate (not shown) comprising a watertight, non-porous and water vapor permeable membrane. The film in contact with the water to be purified releases water vapor 5 due to the permeability of water vapor, and then the water vapor 5 condenses on the top cover 6 and drops into the tank 8 in the form of water droplets 7, where it gathers into The resulting purified water 9 .

[0033] As shown in Figure 2, the evaporation vessel 1 can be equipped with an input 2 and an output 3 for the water to be purified. If the bottom of the evaporation vessel 1 also has a laminate with a watertight, non-porous and water vapor permeable film, it can be placed directly on the ground to moisten the ground, as for example in WO 01 / 10192 as sh...

Abstract

Evaporation reservoir for recovering purified water, with an interior for holding water to be purified, the interior enclosed by walls that are watertight and joined to each other in a watertight manner, at least one wall consisting at least partially of a laminate that has a textile fabric and a watertight, non-porous, and water-vapor permeable membrane, and with an opening for filling the interior, characterized in that at least one edge of the laminate is joined to an edge of the adjacent wall via a tensile-resistant, watertight tape in such a manner that the tensile-resistant, watertight tape is joined on the one hand to the textile fabric and on the other hand watertight to the membrane and extends beyond the edge of the laminate, and the watertight joint with the edge of the adjacent wall is formed exclusively by the part of the watertight tape that extends beyond the laminate. The water evaporating from the reservoir is condensed at a condensation surface arranged above the reservoir and the condensed water is collected.

Description

technical field [0001] The invention relates to an evaporation container for obtaining purified water, the evaporation container has an inner cavity for holding the water to be purified, the inner cavity is surrounded by watertight walls connected to each other in a watertight manner, wherein at least One wall is formed at least partially from a laminate / laminated plastic with a textile surface structure (textilen Flchengebilden) and a watertight, non-porous and water vapor permeable film, the evaporation container Also having a cavity filling opening, the invention also relates to a purified water extraction device / water purification device having at least one such evaporation vessel. Background technique [0002] Evaporation vessels are known, for example, from US 5595662 or WO 00 / 28807. These evaporation containers are used for the purification of water, wherein in use the water is evaporated by a film which closes the container filled with the water to be purified, is ...
