METHOD FOR OBTAINING SEA BRINE IN SALT FIELD, AND STRUCTURE OF SALT FIELD

摘要

PROBLEM TO BE SOLVED: To provide an efficient method and a structure of a salt field, which reduce a large amount of effort.;SOLUTION: In a salt field 1, an impermeable sheet 4 is placed on an inclined surface 3 formed, wherein a sand layer or a pebble layer 5 is formed on the impermeable sheet 4. Sea water is spread on the pebble layer 5 to immerse the pebble layer, and then its water content is vaporized by sunlight to form crystals of salt on a surface of the sand. Thereafter, sea water for dissolving the crystals of salt is spread, and then the sea water flowing on the impermeable sheet 4, in which the crystals of salt are dissolved, is collected as sea brine.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2020,JPO&INPIT
