SALTWATER DISTILLATION HOUSING

摘要

The object of the present invention is to provide a saltwater distillation housing that uses solar energy for efficiently evaporating, condensing, and desalinating saltwater. A housing wall (3) of the saltwater distillation housing opposite an incident wall (2) of solar light (1) comprises an inner vapor current separating plate (6) inside the housing along an outer wall (5) and an outer vapor current separating plate (7) outside the housing; and at the exterior surface of the outer wall (5) covered with the outer vapor current separating plate (7), a water retentive material (8) of non-woven fabric or cotton cloth is attached; and cooling water from the ocean is dispensed on this material (8) from a piping (9) to promote condensation by evaporation. The water basin (4) inside the housing is partitioned into a plurality of water tanks by partitions (19); and a saltwater of a very high salt concentration of a lower layer from an opening (2) at a lower section of the partition (19) is made to flow to the surface of the next section. The air that includes vapor evaporated from the water basin (4) is cooled by the outer wall and is condensed to produce water condensate as it descends through a space between the outer wall (5) and the inner vapor current separating plate (6). By this type of structure, a desalination rate ten times the prior rate is achieved.
