摘要

PPROBLEM TO BE SOLVED: To provide a method which adjusts the amount of a solute contained corresponding to the use of obtained fresh water or concentrated seawater when fresh water or concentrated seawater obtained from deep seawater is utilized for various commodities and performs the efficient desalting and concentration of seawater at normal pressures, and also to provide an apparatus therefor. PSOLUTION: Seawater sampled from deep sea is injected in the vacuum chamber of a vacuum tank wherein a steam chamber is provided around the vacuum chamber through a heat transfer wall and steam overheated to a boiling temperature or higher by high frequency heating under atmospheric pressure is supplied to the steam chamber to heat seawater in the vacuum chamber. Thereby, moisture in seawater is evaporated and condensed to obtain fresh water. Further, concentrated seawater remaining in the vacuum chamber is taken out and, if necessary, moisture of concentrated seawater is further evapolated to obtain salt. Moisture of seawater can be separated in a short time. The content of a solute in distilled water is increased when the vacuum degree of the vacuum chamber is raised, and reduced when lowered. By utlizing such operation, a ratio of a mineral component in the obtained fresh water or concentrated seawater can be changed. PCOPYRIGHT: (C)2004,JPO

要解决的问题：提供一种方法，当深海水中获得的淡水或浓海水用于各种商品时，可以根据所获得的淡水或浓海水的使用来调整所含溶质的量，并能有效地解决上述问题。在常压下对海水进行脱盐和浓缩，并为此提供一种设备。

解决方案：从深海中抽取的海水注入到真空箱的真空室中，其中通过传热壁在真空室周围提供一个蒸汽室，并且在大气压下通过高频加热将蒸汽过热至沸腾温度或更高向蒸汽室提供压力以加热真空室中的海水。从而，海水中的水分蒸发并冷凝以获得淡水。此外，将残留在真空室中的浓缩海水取出，并且如果需要，进一步蒸发浓缩海水的水分以获得盐。可以在短时间内分离出海水中的水分。升高真空室的真空度时，蒸馏水中的溶质含量增加，降低时，溶质含量降低。通过进行这样的操作，可以改变所获得的淡水或浓缩海水中的矿物质成分的比例。
