Abstract
A method and apparatus for desalinization of salt water to render it potable, wherein the salt water at ambient temperatures is forced through multi-stages at high centrifugal velocities, generating heat to vaporize the water to water vapor, and separating and suspending the salt and other minerals in the water vapor. The centrifugal force separates the salt and other minerals for discharge separately from the water vapor or steam so that the water vapor may be condensed to essentially mineral-free potable water.
Claims5
A method for removing dissolved salt and other minerals from water, comprising the steps of:
- introducing water having dissolved salt and other minerals therewith into a housing;
- flowing the water having dissolved salt and other minerals therewith through a series of stages formed of a series of rotatable trays alternately separated by a series of fixed stop plates in the housing;
- heating the water in each successive tray and stop plate stage to effect the vaporization of the water to produce water vapor having at least some of the dissolved salt and other minerals separated from and suspended in the water vapor, substantially solely by rotating the trays at a sufficiently high velocity;
- swirling the water vapor, salt and minerals to exert a centrifugal force on the water vapor and the salt and minerals to physically separate the salt and minerals from the water vapor within the housing;
- and,
- thereafter removing the separated salt and minerals from the housing apart from the water vapor.
