Description

[Detailed Description of the Invention] (Industrial Application Field) In arid, semi-arid, or coastal lands, only water with high salinity, such as fossil water or seawater pumped up from deep underground, is available, making it difficult for crops to grow. Although cultivation is not possible, this invention relates to a pure water production device using solar heat to make it possible to supply water to crops in the above-mentioned land.

(Prior Art) FIG. 5 is a block diagram of a conventional pure water production apparatus using solar heat. The deionized water production device 30 has a transparent cover 31 made of glass or a vinyl sheet, etc. installed obliquely toward sunlight, a two-leaf house 32, a distilled water receiver 33 attached to the lower end of the transparent cover 31, and deionized water. It consists of a storage tank 34. By the way, in order to make the vinyl house 32, it is necessary to assemble the frame 35 and stretch the vinyl sheet. Note that 36 indicates raw water such as fossil water or seawater, and 37 indicates high temperature humid air.

(Problem to be solved by the invention) A conventional pure water production device using solar heat has a transparent cover 31.
raw water by the thermal energy of sunlight collected through
6 is heated and evaporated to generate high-temperature humid air 37, the condensed water generated by the condensation of the humid air 37 is transmitted diagonally downward along the lower surface of the transparent cover 31, and the condensed water is transferred to the distilled water receiver 33. The principle is simple, but collecting a large amount of pure water requires a vast area and is a large-scale device, so consideration must be given to the effects of typhoons, etc. This makes construction extremely difficult.

Therefore, it can only be applied to extremely small-scale operations such as obtaining a small amount of drinking water or conducting science experiments. Therefore, it is an object of the present invention to enable the construction of a pure water production apparatus using solar heat to be easily carried out without being affected by the size of the area.

(Means for Solving the Problems) A feature of the solar heat-utilizing pure water production device according to the present invention is that the plurality of connected covers that transmit sunlight are made of transparent and light-resistant material. The rectangular plate is bent to form a chevron shape, and a gutter is integrally formed inside both lower edges to collect the distilled water that flows down, and the raw water storage part is made of a black color with many protrusions on the surface. The reason is that it is formed using a plastic evaporation plate.

(Function) Raw water, such as water with a high salt concentration, stored in the storage section is evaporated by the thermal energy of sunlight, becomes condensed water on the lower surface of the transparent chevron cover, and is integrated into the lower end of the chevron cover. The distilled water flows down into the formed distilled water collection trough, from which pure water is collected.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

Figure 1 is a perspective view of a transparent plastic or glass chevron-shaped cover formed by bending a square plate approximately along the center line, and distilled water collection gutter IA is located along the inside of both lower edges of the chevron-shaped cover 1-. Inset projections IB and I for continuous installation along the outside
C are each integrally molded.

Fig. 2 is a perspective view of a solar heat-utilizing pure water production device that is connected on the chevron-shaped cover, in which 2, 2'' are columns erected on the ground, and column 2 at the front end is a column at the rear end. It should be shorter than 2゛. Therefore, the support plate 3 placed and fixed on the pillars 2, 2'' is installed at an angle.The surface of the support plate 3 is covered with a water-impermeable sheet 4 such as aluminum foil, and a suitable thickness is A black fiber sheet 5 such as an inorganic yarn having a thickness of It is covered with a shielding plate 6, and the lower side thereof is covered with a secondary distilled water wall board 7 which also serves as a shield. 7A indicates a secondary distilled water collection gutter, and an excess salt water collection gutter 8 is provided inside it. 9 is a pipe for supplying raw water such as salt water by a pump or by gravity flow, and is installed at the uppermost end of the water purifier, and has a large number of tubes 10 branching from the pipe 9.

The tip of the tube 10 is opened toward the upper end of the black fiber sheath 1 and 4. Note that 11 indicates a pipe support.

FIG. 3 shows a sectional view of the pure water production apparatus using solar heat shown in FIG. 2.

Since the present embodiment is as described above, when raw water such as salt water is supplied to the pipe 9 by a pump or gravity flow, it drips onto the upper end of the black fiber sheet 5 through the many tubes 10, and drips onto the entire surface of the sheet 5. Moisturize. Then, the raw water is heated by the black fiber sheet 5 that absorbs solar heat, evaporates, and becomes condensed water on the upper and lower surfaces of the above-mentioned chevron covers, which are connected in series.
The distilled water flows down into the distilled water collection gutter IA, from which pure water can be recovered via the secondary distilled water gutter 7A.

Incidentally, the surplus salt water on the black fiber sheet 5 flows down into the salt water collection gutter 8 and is collected.

In addition to the raw water storage section of this embodiment, which is composed of the above-mentioned water-impermeable sheet 4 and the black fiber sheet 5 laid thereon, a raw water storage section using a black plastic evaporation plate shown in Fig. 4 is adopted. You can also.

That is, in FIG. 4, the bottom of the shallow box-shaped container piece is made of a black plastic evaporation plate 13, and a large number of protrusions 13A are formed on the surface of the evaporation plate 13 to uniformly flow raw water such as salt water. Reference numeral 4 is an elastic stopper for attaching the above-mentioned box case to the transparent chevron-shaped cover, and the reference numeral 15 indicates an elastic stopper that is snapped into the distilled water collection gutter IA. Since the container fertilizer can be easily attached and detached from below on the transparent chevron-shaped cover, it can be easily replaced if salt is stuck and accumulated on the evaporation plate 13.

Note that this embodiment is most suitable for drip irrigation in agriculture, and generally for the production of drinking water.

(Effect of the invention) According to this invention, the following effects can be achieved.

■There is no need to install a frame, cover the frame with glass or vinyl, or install a gutter to collect distilled water, which was conventionally done to collect distilled water above the water surface. be.

■In terms of construction and cost, compared to the conventional method of storing salt water in a shallow aquarium and installing a frame on top of it, the present invention uses plates, opaque sheets, inorganic threads, etc. based on the adoption of a chevron cover. It is more advantageous to use a black fiber seal l- or a black plastic ink, iJ evaporation plate, which has a large number of protrusions on its surface.

■By connecting chevron-shaped covers in series, it is possible to create a device with any area, and in addition, no complicated technology is required for construction.
