Abstract

PROBLEM TO BE SOLVED: To drastically reduce water and the period of time required for remov ing the salt content when washing sea with water by forcibly sucking washing water from the bottom part of a pool. SOLUTION: Sea sand S is placed on a water-passable tank 14 consisting of gravel, a drain material and the like and water is sprinkled over the sea sand by a shower device 12. The shower device 12 is not specially limited. Water sprinkled from the shower device 12 falls downward from above between the sea sands S as shown by the arrows. At this time, suction pressure from vacuum pumps P is applied to the bottom part of a pool 11 through plural drain members 13 to make the tank 14 around the drain members 13 in a negative pressure state. And by this negative pressure, sea water falling from above downward through sea sand S is forcibly sucked. On account of this, salt content removing efficiency and falling velocity of washing water when passing through the sea sand S are doubled, allowing water and a period required for removing the salt content to be sharply reduced.

As shown in FIG. 1, the sea sand S is washed with a shower device 12 from above the sea sand S put into the pool 11.
It is performed when water is applied by using water or the like, and the water falls between the sea sands S from above to below as shown by arrows in the figure. That is, the water falls while contacting the sea sand in the process of passing between the sea sands S. At this time, the salt and silt contained in the sea sand dissolve into the water, and the sea sand S is washed with water.

The sea sand S is placed on the permeable layer 14 and sprinkled on the sea sand S by the shower device 12. The shower device 12 is not particularly limited, and any conventionally known device can be used. Preferably, the embodiment shown in FIG. 1 and FIG. 5 can be mentioned. The water sprinkled from the shower device 12 is originally applied to sea sand, but the water droplets from the shower device are also small,
When it becomes mist, or when it is fanned by a strong wind, it may be scattered around the pool 11 without being sprayed into the pool 11. When the water droplets become mist, a part of the sprinkled water sometimes evaporates on the way.

Therefore, in the embodiment shown in FIG. 1 and FIG. 5, even if the sprinkled water droplets are enlarged and fanned by the wind, they do not scatter around the pool 11 and do not evaporate. That is, the shower device shown in FIGS. 1 and 5 includes a shower nozzle 20 connected to a water source, a nozzle 2
0, and a net body 21 for receiving water spouted from the nozzle. The water from the nozzle 20 is once received by the net body 21, where the water drops into sea sand S as large water droplets. It has become. The size of the water droplet can be adjusted by appropriately adjusting the size of the eyes of the net body 21 and the thickness of a wire (preferably a hydrophilic string, thread, or rope) constituting the net body 21. In the case of this mode, the shower nozzle 21
