摘要： PURPOSE:To efficiently take out fresh water from sea water, by use of a compact equipment, by cooling from the outside by sea water, jetting hot sea water from the upper part of a separating chamber in a hollow frame which is made vacuum, converting a mistlike substance of light specific gravity, having no salt to a water drop, and catching it by a gutter. CONSTITUTION:The inside of a separating chamber 2 is made vacuum by a vacuum pump 3, also cooled sea water is jetter 8 and is made to flow down onto a hollow frame 1, and the frame 1 is cooled. In this state, sea water in a sea water reservoir 6 is supplied 10 to a heater 12 by a pump 11, and for instance, it is heated to 80 deg.C, and is jetted into the chamber 2 from an ultrasonic shower 9. A mistlike substance generated by this jet is separated by specific gravity in the chamber 2, and a substance of heavy specific gravity, having salt is dropped as it is and is dishcarged. On the other hand, a mistlike substance of light specific gravity, having no salt is floated in the chamber 2, also a water drop generated by cooling is made produced water, is caught by a gutter 13, and is taken out through a take-out pipe 15. Also, the mistlike substance of light specific gravity, which is floating in the center part is caught by an inside gutter 16.

摘要： PURPOSE:To enable to perform efficient desalination, by mixing sea water with lime to stick a slat part to the lime, supplying the mixed liquid to the smaller- diameter side of a rotary die whose inner surface is tapered, centrifugally separating it in the rotary die, and withdrawing product water from the inside. CONSTITUTION:Sea water and lime are mixed together in a pool 12 to stick a salt part to the lime. The mixed liquid is sucked up into a supply pipe 19 by the operation of a pump 18, supplied to the smaller-diameter side of a rotary die 1 whose inner surface is tapered, and centrifugally separated in the rotary die 1. On this occasion, the sea water is reformed into fresh water since the salt part adheres to the lime. consequently, the sea water is centrifugally separated into fresh water as product water and lime sludge. The lime sludge is discharged in a lime-receiving duct 11 through a withdrawing passage 8 at the outside of a larger-diameter side, while the product water is withdrawn in a product water- receiving duct 10 through another withdrawing passage 7 at the inside. In succession, the lime sludge withdrawn in the duct 11 is separated by a means 21, and sea water near akin to the procduct water is returned through a pipe 23 to the pool 12.

摘要： PURPOSE:To enable to perform inexpensive desalination, by laying a water- proof membrane under a film buried near the surface of a desert, evaporating the water part of sea water supplied onto the water-proof membrane by solar heat, sucking the evaporated water by a suction pipe between the film and the water-proof membrane, and then cooling it. CONSTITUTION:A film 2 is buried near the surface of a desert 1, and a water- proof membrane 3 is laid under the film 2. Under the condition that a suction pipe 4 is provided near the film 2 between the film 2 and the water-proof membrane 3, sea water is supplied onto the water-proof membrane 3, its water part is evaporated by solar heat, and the resulting steam is sucked by the pipe 4 and cooled to make product water. With the laps of a desalinating time, sea water having the high concentration of salts accumulated on the membrane 3 is discharged through a pump 15 and a pipe 16. In this desalination method, the whole of arrangements can be made small in size since several pumps 5, 8, 10, 13 and piping only are necessitated, and the running cost can be lowered since solar heat is utilized as the heat source to separate the water part from sea water.

CONSTITUTION:By a vacuum pump 3, the inside of a separating chamber 2 is made vacuum, also cooled sea water is jetted 8 and is made to flow down, and a hollow frame 1 is cooled. In this state, sea water in a sea water reservoir 6 is fed 10 to a heater 12, and for instance, it is heated to 80 deg.C, and is jetted from an ultrasonic shower 9. Subsequently, a generated mistlike substance is separated in the chamber 2, and a substance of heavy specific gravity, having salt is dropped to the lower part and is discharged 22. On the other hand, a mistlike substance of light specific gravity, having no salt is converted to vapor in the chamber 2, and to the losely fitted mistlike substance of light specific gravity, the magnetic powder converted to a water solution is jetted 23. Subsequently, this magnetic powder body is made to a nucleus, to which the mistlike substance of light specific gravity is made to adhere, it is made to a small water drop, is adsorbed to the inside surface of the frame 1, is cooled and is converted to a large water drop. This large water drop is made to producing water, is caught by a gutter 13, is taken out to a pipe 15, and thereafter, both of them are separated by a magnetic powder separating device 26.
