Abstract

<P>PROBLEM TO BE SOLVED: To provide a seawater desalination system which effectively functions as a countermeasure for draught and a countermeasure for afforestation of desert in a system of desalting and utilizing nearly the infinite seawater and is helpful for water shortage at a low cost. <P>SOLUTION: The sea water desalination system is a mechanism of allowing the seawater to dive into multiple layers of the sand as a practical filter, so as to stick its salt component to the particles of the sand, then once pouring the water into a river installed under the ground and moving the seawater, then pumping up the water from a well after carrying the water to a necessary place by noticing the performance of the sand to stick the salt component in a salt making process in a salt farm. At this time, the separation of the moisture and the salt component is made thorough by covering the ceiling of the river under the ground with cloth or materials, such as spongy materials, and using the ceiling materials which do not allow the permeation of the sand and allows the permeation of the water. The water is pumped up by utilizing wind power generation in continuously supplying a large volume of the seawater from the inside of the sea and therefore the desaaliation is made possible at the extremely low cost. According to the present invention, the system is greatly helpful for the countermeasure for the drought of the earth. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

BACKGROUND OF THE INVENTION Conventional seawater desalination methods have required the use of different energies to separate seawater into water and salinity. In other words, seawater is boiled at a high temperature to evaporate water, and the water vapor is collected and cooled to be used as water. Therefore, there is a problem in continuously producing a large amount of extra cost and water.
[Solution to solve the problem] This seawater desalination technology focuses on the fact that sand itself has the property of adhering salt from seawater from the salt production method using salt fields, and seawater is immersed in multiple layers of sand to remove salt and moisture. We succeeded in solving the problem by separating large quantities of water from seawater at low cost and continuously using it by separating the water and creating an underground river and pumping and using the accumulated water. Way.
[Action] It is very useful for environmental measures such as drought control and greening of desert.

The sand acts as a filter to convert seawater into freshwater and separates it into salt and water. Create a river surrounded by rocks or concrete of high strength under the sand, and cover with a cloth or sponge-like material that does not allow sand particles but allow water to flow, so that water is collected in the river and water flows underground. To Water is pumped from the seawater by a wind power generator using a motor, carried by a gutter to a sand field, and the seawater is poured on the sand. ， A mechanism to pump and use the water.
