<P>PROBLEM TO BE SOLVED: To solve the following problems: a small-scale solar salt production method can not stably remove water contained in seawater because of the influence of weather nor remove water contained in seawater during nighttime when there is no irradiation with sunlight, and requires large-scale equipment in order to stably produce salt for 24 hours, whereas a large-scale production method consumes a large amount of other energy in a salt production process, resulting in global environmental destruction. <P>SOLUTION: A nonconventional, epoch-making salt production technology is provided by which water contained in seawater can be stably removed for 24 hours without being influenced by weather by utilizing geothermal heat. The salt production technology does not require a large-scale equipment in order to stably produce salt for 24 hours, and by the technology, salt can be produced with a drastically reduced consumption of energy other than geothermal heat energy without almost causing an adverse effect on natural environment, and the problems wherein time, labor and cost are most required for removing water contained in seawater in an amount of 97% in a conventional salt production method and the like can be solved. <P>COPYRIGHT: (C)2009,JPO&INPIT |
