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

FIELD: various technological processes.

SUBSTANCE: invention relates to devices for producing 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 reservoir. 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. From the end of the channel, located at the surface of sea water, there are through branches ending at the opposite wall of the container, which are identical in shape and size to the channel itself, number of which varies from one to three, located at angles of 5, 10 and 15°, respectively to its lower surface.

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