DEVICE FOR OBTAINING FRESH WATER FROM ATMOSPHERIC AIR Russian patent published in 2024 - IPC E03B3/28 B01D5/00 

FIELD: methods and apparatus for producing or collecting water.

SUBSTANCE: invention relates to production of fresh water from water vapours contained in ambient air. Device contains an open-top container immersed into a reservoir with sea water so that its walls extend beyond the water surface. Inside the container there is a through channel for sea water flow, located between two opposite walls of the container and arranged so that one end of the channel is located at the water surface, and the other one is lower with an inclination within range of 20–45°. Cross-section of the channel has the shape of a triangle, the base of which faces the bottom of the container, and the top faces the surface of the water reservoir. Length of the triangle base is less than the width of the container in the direction perpendicular to the arrangement of the channel. Angle between the lateral edges of the triangle lies in range of 90–140°. In the immediate vicinity of the above end of the channel in the sea water there is an actuating mechanism of a wind energy converter. Latter is composed of a rotating shaft with a blade mechanism for injecting sea water into the channel attached from the outside to the side surface of the container by means of a fastening device. Container is located at the surface of the water reservoir by floats. Upper edge of the container is equipped with visors facing the centre of the container at an angle to the horizontal plane. Above the channel there is a solar collector fixed on the side surfaces of the container, having through holes in the vertical direction, which is located so that there is an air gap between its lower surface and the upper surface of the channel. Additional through channel for sea water flow, identical in shape and size to the first one, is located in addition to the through channel for sea water flow and is mirror to it with respect to the central vertical plane, in the immediate vicinity of which at its end, which is located above, there is an additional wind energy converter fixed from the outside to the side surface of the container due to an additional fastening device. In the area of channels intersection, they have a common volumetric part. Solar collector is also located above the additional through channel for sea water flow.

EFFECT: increased area of condensation of the device and increased volume of produced fresh water.
