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 below 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. In addition to the through channel for sea water flow under it in the same way as it, additional channels of similar shape and size are made in number from three to five, arranged one above the other at distance of 10 to 15 cm from the lower surface of the previous one to the top of the next one. Distance from the lower surface of the lower channel for sea water flow to the lower surface of the container is not less than half of its height. Wave energy converter is equipped with a device providing sea water pressure in all channels for sea water flow.

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