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 at the surface of the water, and the other 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 body. Length of the base of the triangle is less than the width of the container in the direction perpendicular to the arrangement of the channel, while the angle between the lateral ribs of the triangle lies within 90–140°. In the immediate vicinity of the above end of the channel in the sea water there is a wave energy converter fixed 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 body 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. In addition to the through channel for the sea water flow, an additional through channel for the sea water flow, identical in its shape and dimensions to the first, is located mirrored to it in relation to the central vertical plane, in the immediate vicinity of which at its end located above the wind energy converter actuator is located, which is composed of a rotary 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 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.
