METHOD OF FRESH WATER PRODUCTION AND DESALTER FOR ITS EMBODIMENT Russian patent published in 2002 - IPC

FIELD: methods and desalters for production of fresh water from sea and mineralized waters and industrial waste water. SUBSTANCE: method includes supply of preliminarily heated saline water to evaporation chamber, its evaporation, condensation and collection for user. Additionally performed parallel supply of fresh water to condensation chamber where it is used for catching and condensation of saline water steam and separation of excessive amount of fresh water for user. In so doing, supply of saline and fresh waters to evaporation chamber is carried out in two stages including rarefaction and pressing. Volume of supply of fresh water exceeds that of supply of saline water. Temperature of saline water, in this case, exceeds temperature of cold water at least by 18 C. Desalter has an evaporation chamber, condensation chamber and system of pipelines with valves for supply and discharge of saline and fresh water, fresh water tank with system of its cooling and supply to condensation chamber, and body whose bottom and cover accommodate partitions separating saline and fresh waters. Located between body and cover are panels with holes or injectors through which saline and fresh waters in the form of drops run off into evaporation and condensation chambers separated by a separator. Located inside condensation chamber are vacuum header connected with a vacuum pump via shutoff valve, and also cooler, reservoir for heating of saline water and tank accumulating saline water. Desalter is also provided with indicators of levels of filling the evaporation chamber, condensation chamber and tanks of fresh water. System of pipelines with valves for supply and discharge of saline and fresh waters includes pump valves, flow meters and filters. EFFECT: reduced energy consumption per unit of volume of product - fresh water due to simple method and desalter reliable in operation and simple servicing of desalter and process. 14 cl
