Definitions
- the present invention is related to a saltwater distillation housing for extracting distilled freshwater from saltwater using natural renewable energy in desert, isolated islands, other areas where obtaining freshwater is difficult.
- Desalination of ocean water and underground saline water is one of the most important topics in desert and other areas where fresh, life— sustaining water is in short supply.
- desalination is achieved generally by burning oil or using reverse osmosis technology in a large facility where a tremendous amount of non-recyclable energy is required.
- a basin evaporation method that involves a small self-sufficient facility utilizing natural energy such as thermal energy from the sun.
- the basin evaporation method requires placing a basin containing a certain amount of saltwater in a housing and collecting the resultant condensate cooled and condensed on the housing wall by the outside air.
- efficiency ' i this method is very low; for instance, a basin with an open surface area of 400 m 2 would lead to extracting only 1 m 3 of distilled freshwater per day.
- the aforementioned method using solar heat has an extremely bad condensation rate because the vapor evaporated from the basin containing the saltwater can freely disperse away from the housing wall without being adequately cooled for condensation. Furthermore, there is a problem of a higher temperature saltwater of a very high salt concentration having an efficient evaporation rate being layered over by a lower temperature saltwater of a very low salt concentration having an inefficient evaporation rate, resulting in overall an inefficient evaporation of the saltwater.
- the object of the present invention is to solve the problem as described above by using solar heat to efficiently evaporate saltwater as well as to present a saltwater distillation housing that can efficiently condense and desalinate saltwater.
- a saltwater distillation housing of the present invention uses the following means.
- the invention provides a saltwater distillation housing for extracting freshwater from water vapor of saltwater evaporated within the housing, characterized in that an inner plate inside the housing is placed along the outer wall of the housing with a space between the outer wall and the inner plate, and freshwater is extracted by cooling a vapor current passing through the space within the housing.
- the vapor current of the inner housing is cooled within the space between the inner plate and the outer wall by the outer wall; and since this cooled vapor current is prevented from dissipating by the inner plate, cooling and condensation processes are facilitated in the formation of water condensate for desalinating the saltwater.
- the present invention further comprises means for adjusting the flow rate of the vapor current at a current outlet at which the vapor current flows through the space between the inner plate and the outer wall and out into the housing.
- the speed of the vapor current passing through the space between the inner plate and the outer wall can be selectively set, and thereby, effectively executing cooling and condensation processes.
- the present invention is further characterized in that an outer plate is placed along the outer wall at an exterior side of the housing with a space between the outer wall and the outer plate, and outside air made light in weight by being warmed by a heat exchange process between the interior and exterior sides of the outer wall becomes a rising vapor current that passes through the space between the outer wall and the outer plate to further promote heat exchange between inside and outside of the housing through the outer wall.
- the present invention further comprises water dispersing means for dispersing cooling water on an exterior surface of the outer wall to cool the outer wall effectively.
- the present invention further comprises a water retentive material of non-woven fabric or cotton cloth for absorbing the cooling water at the exterior surface of the outer wall.
- the present invention is further characterized in that a basin having a plurality of water tanks connected together by water passage channels are placed inside the housing, have the water passage channels positioned at a lower part of the water tank, and let pass saltwater of a lower layer of the water tank. According to this construction, a heated reserved water of a high salt concentration at the lower layer is progressively brought to the surface as the water is transferred to the next tank.
- the present invention is further characterized in that the basin is divided into the plurality of water tanks by partitions, each having an opening at a lower part of the basin, and these water tanks constituting the basin are integrally constructed. In this way, the water tanks are constructed with relative ease.
- a housing wall panel of a saltwater distillation housing for extracting freshwater from water vapor of saltwater evaporated inside the housing, comprising a wall plate that separates inside and outside of the housing, an inner plate placed at a predetermined spacing along the wall plate and at an interior surface side of the housing, and an outer plate placed at a predetermined spacing along the wall plate and at an exterior surface side of the housing, and these components are integrally constructed.
- the housing wall panel of a vapor current separating construction leads to cooling the vapor current between the inner plate and the outer wall by utilizing effectively the outside air that rises between the outer plate and the outer wall; and by prefabricating these plates, they can be used to easily construct the saltwater distillation housings anywhere.
- the present invention further comprises a piping for dispersing cooling water on an exterior surface of the wall plate. By the dispersion of the cooling water, the wall plate can be effectively cooled.
- the present invention further comprises a water retentive material of non-woven fabric or cotton cloth placed on the exterior side of the wall plate. The process of evaporation is promoted by letting cooling water absorb into this water retentive material.
- Still another embodiment of the present invention is a basin, including a plurality of water tanks for letting pass saltwater, for evaporating a water component of the saltwater in the water tanks by solar heat, characterized in that the basin has water passage outlets for progressively transporting between the water tanks, saltwater of a lower layer of the water tanks. In this way, water tanks can be presented that progressively transfer the heated water of a high salt concentration of the lower layer to the surface and evaporate the water component.
- the present invention is further characterized in that the water tanks constituting the basin are integrally constructed with partitions that divide the water tanks, and an opening for letting pass saltwater of the lower layer is provided at a lower part of each partition. In this way, a plurality of water tanks having a very simple structure that effectively evaporate saltwater can be easily constructed.

- FIG. 3 is a cross-sectional view of arrow III-
- the saltwater distillation housing uses the vapor current separating structure in a housing wall 3 opposite an incident wall 2 where solar light 1 irradiates on it. Furthermore, a basin 4 is provided r D in the housing for holding saltwater to be evaporated by solar heat.
- the vapor current separating structure of the housing wall 3 includes an inner vapor current separating plate 6 along an outer wall 5 and inside the housing.
- the saltwater vapor current that passes through an inner space 26 provided between the inner vapor current separating plate 6 and the outer wall 5 is cooled and condensed while descending the space and turns into liquid to produce freshwater.
- descending speed of the saltwater vapor current is made to be adjustable by providing current rate adjustment means 28 comprising a structure such as an adjustment valve for constricting an opening for adjusting the current rate at an exit mouth in the lower section where the vapor current of the inner space 26 circulates out into the interior of the housing.
- an outer vapor current separating plate 7 is provided along the exterior side of the outer wall 5. Still further, a water retentive material 8 of non-woven fabric or cotton cloth is placed on an exterior surface of the outer wall 5 which is further covered by the outer vapor current separating plate 7; and by dispersing cooling water such as saltwater from a piping 9, this water retentive material 8 is made to absorb the cooling saltwater. As this cooling saltwater evaporates, the outer wall is cooled and the cooling of the vapor current in the inner space 26 is promoted to achieve efficient condensation. On the other hand, outside air, warmed and made light in weight by heat exchanging with the inner housing through the outer wall 5.
- a freshwater collecting channel 10 is provided on the floor of the inner housing for collecting the water condensate produced within the inner space 26.
- a water drainage channel 11 for the cooling water dispersed within the outer space 27 is provided.
- the vapor current separating structure of the housing wall 3 is, as shown in FIGS. 2 and 3, provided with the inner and outer vapor current separating plates 6 and 7 held in place by, for example, an acrylic plate fixing support material 15. Predetermined spaces set by interval adjustment materials 13 and 14 are provided between the plates 6 and 7 respectively with respect to the outer wall 5, which is placed on rafters or hanging wood 12 with a packing material 16 therebetween.
- the outer wall 5 and the inner and outer vapor current separating plates 6 and 7 are acrylic plates, but the present invention does not need to be limited to acrylic material. Glass, plastic or other transparent material may also be used. That is, a preference is made to a material that is easily handled, does not break easily, and has excellent durability.
- the inner and outer spaces 26 and 27 of the outer wall do not need to be equally spaced apart, and although in the present structural embodiment, for example, theses spaces appear to have equal spacing above and below the wall but this is not always necessary to conduct desalination.
- the solar light incident wall 2 of the housing has an acrylic plate 17 on the hanging wood 12 with the packing material 16 therebetween and is held in place by screws 18.
- a known structure may be used so long as solar heat irradiates on the wall adequately.
- FIG. 4 is a planar view of one structural embodiment of the basin 4 of the present invention.
- FIG. 5 is a detailed view of arrow V-V in FIG. 4.
- the basin 4 placed on the ground inside the housing is divided into a plurality of water tanks having oblong and large length to breath ratio (figure shows 9 tanks); and an opening 20 for transporting a saltwater of a very high salt concentration from one tank to the next is provided at the lower part of each partition 19. Two openings for every one tank are placed at the farthest ends.
- the basin 4 in the present structural embodiment has a waterproof sheet 22 overlaid on a bottom plate 21 and is divided by the partitions 19 and processed to prevent water leakage by a caulking 23. It is a structure that can be easily manufactured.
- the air current containing water vapor warmed in the housing, as shown as arrow 24 in FIGS. 1 and 2, is cooled while descending through the inner space 26 provided between the inner vapor current separating plate 6 and the outer wall 5, and then the vapor phase and the liquid phase are separated by condensation because of cooling.
- the liquid phase results into water condensate which drips into the water collecting channel 10 used for collecting freshwater, and the vapor phase travels down as it loses moisture and circulates into the interior of the housing from the outlet at the lower section. In this way, evaporation of saltwater within the basin 4 is promoted.
- the descending speed of the vapor current within the inner space 26 can be selectively set to execute the condensation process effectively.
- the outside air is warmed and made light in weight as the weight of the vapor evaporated at the outer wall 5 is less than half that of the air (air to vapor ratio is approximately 0.45).
- This air as is contained within the outer space 27 formed by the outer vapor current separating plate 7 and as shown as arrow 25 in FIGS. 1 and 2, becomes a strong rising current, and the air sucked from the bottom of the outer vapor current separating plate 7 promotes evaporation as it passes over the exterior surface of the outer wall 5.
- the water retentive material 8 of non-woven fabric or cotton cloth — materials that can absorb water easily — is attached on the exterior side of the outer wall 5 and saltwater is dispensed to moisturize the material 8.
- the saltwater for cooling purposes dispersed on the exterior surface of the outer wall 5 is drained through a water drainage channel 11 before any salt crystals can form. It is also possible to extract salt from the saltwater to be drained.
- the inventor therefore, used a plurality of long water channels in the water tanks 4, where each tank is made to have an opening 20 to let flow the saltwater in or out of the lower layer.
- the openings 20 at the lower sections of the partitions 19 were positioned alternately and diagonally with each other.
- a heat reserved water of a high salt concentration of the lower layer in one tank flows into the adjacent tank through the opening 20 to form an upper layer.
- the supplied saltwater passes through the oblong tank while evaporating; the saltwater of the lower layer flows through progressively through the openings such that the heated water of a very high salt concentration of the previous tank comes up progressively to the surface of the next tank to have the water component evaporated.
- the water of the lower layer from the previous tank rises to the surface of the next tank because it is assumed that the salt concentration is higher in the next tank owning to continuing evaporation.
- An air current that includes water vapor inside the housing turns to liquid according to the condensation process while descending through the space between the inner vapor current separating plate and the outer wall and forms water condensate which drips off below.
- Outside air warmed by the heat exchange between inside and outside of the outer wall, becomes light in weight and turns into a rising air current, rising from the lower section of the outer vapor current separating plate, and promotes evaporation by passing over the exterior surface of the outer wall. This evaporation causes the housing inside to be cooled as heat exchange occurs.
- the outer wall is cooled by having water evaporate from the water retentive material, which is attached onto the exterior side of the outer wall, previously soaked with cooling water.
- the inner housing side of the outer wall is cooled to promote condensation.
- the water basin is partitioned into several tanks by the partitions that have openings at the lower part, the heat reserved water of a very high salt concentration of the lower section progressively passes through each of the tanks through the openings to come up to the surface to have the water component evaporated.
