METHOD FOR PRODUCING WATER FROM AIR Russian patent published in 2017 - IPC E03B3/28 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of autonomous production of fresh drinking water from the moisture of surrounding maritime atmospheric air and can also be used for domestic and economic needs. The method includes the use of generators (11) of pneumatic energy. The compressed air flow after the generators (11) is cooled in the condensers (6) with precipitation and moisture intake. Atmospheric air sampling is carried out in the vicinity of the sea surface, where its humidity is maximum. The generators (11) of pneumatic energy are actuated with the tidal energy. The generators (11) are made in the form of hydraulic units which are placed in the tidal zone ensuring the seawater banking in front of them. On the hydraulic units having radially movable walls in the form of membranes (1) the air compression chambers (3) with suction and discharge valves are mounted. In the hydraulic units the periodic hydraulic shock is initiated, which results in reciprocating motion of the membrane of the air compression chambers (3) and generating the pneumatic energy in the compression chambers (3). After the condensers (6) the air is directed to the air expanders made in the form of throttles or pneumatic motors (10). The pneumatic motors (10) are connected to the electric generators (11). The obtained electrical energy is used to drive the pumps (14) for pumping the settled fresh water from the condensers (6) and moisture-receivers (12) of the air expanders. When throttles are used as air expanders the fresh water is pumped from the moisture-receivers (12) by ejecting it with fresh water under pressure located in the condensers (6). The condensers of moisture (6) are placed under the sea level and cooled with sea water.

EFFECT: conversion of hydraulic energy of sea tides into pneumatic energy necessary to extract the moisture contained in the atmospheric maritime air.
