WELL FOR RECOVERING WATER FROM ATMOSPHERIC AIR Russian patent published in 2018 - IPC E03B3/28 

FIELD: water supply.

SUBSTANCE: invention relates to water supply and can be used to obtain water in arid areas to provide the population with drinking and domestic water. Well includes an inlet device, a condensation tank (1) and a water collecting tank (20), a device for drawing water from the water collecting tank (20). Device is used to produce water through ventilation, which forms a stream of air containing water. Condensation tank (1) and outlet device (4) are arranged so that the air flow is cooled when passing tank (1), and water vapor condenses and the resulting fresh condensate water drains into tank (20). For supplying cold air and creating an active convention zone, the well is equipped with a vertical air pressure pipe (11) introduced into a fiberglass-reinforced well. Pipe (11) extends to air-permeable granite rubble in the form of granules and is a perforated pipe of a smaller diameter (8), through which cold compressed air is supplied. Pipeline (8) is placed in the cavity of the main pipeline of larger diameter (7), made in the form of a perforated casing. Main pipeline is made of polyethylene material. Pipe inlet (11) is connected to the injection device in the form of an impeller (12), from which cold compressed air is fed into the pipe (11) with a check valve (13) installed at the beginning of the pipe (11). Condensation tank (1), filled with granite rubble (6) in the form of granules, plays the role of increasing contact with cold compressed air. Lower part of the well is made in the form of a water collecting tank (20) and is equipped with a closed arch-type structure on top of it with a hemispherical vault with a perforated coating in the form of mesh partitions above (21) and below (22) the closed structure, inside which a geotextile filter material (23) is placed.

EFFECT: simplicity and reliability of design, constant and/or adjustable supply of cold compressed air.
