DEVICE FOR FRESH WATER PRODUCTION FROM ATMOSPHERIC AIR Russian patent published in 2021 - IPC E03B3/28 C02F1/14 

FIELD: chemistry.

SUBSTANCE: invention relates to devices for the fresh water production from water vapours contained in ambient atmospheric air, and can be used to produce fresh water mainly in the coastal with the seas regions. Device consists of container with open top submerged into water reservoir with sea water so that its walls extend beyond water surface. Upper edge of container is equipped with caps to prevent ingress of splashes from sea waves, which are directed to centre of container at an angle to horizontal plane. Inside the vessel there is a through passage for sea water flow, located between two opposite walls of the reservoir and arranged so that one end of the path is located at the water surface, and the other one is below with an inclination, which is within 20–45°. In its cross-section the path has the shape of a triangle, the base of which faces the reservoir bottom, and the vertex faces the surface of the reservoir. Length of base of triangle is less than width of container in direction perpendicular to arrangement of path. Angle between lateral ribs of the triangle is within 90–140°. Above the path there is a solar collector fixed on side surfaces of the reservoir, having through holes in vertical direction. Solar collector is arranged so that between its lower surface and the upper surface of the path there is an air gap. In close proximity to the above end of the channel in the sea water there is an actuator of the wind energy converter, which is a rotating shaft with a blade mechanism for injecting sea water into the path. Wind energy converter is attached from the outside to the container side surface due to the fastening device. Fresh water vessel is located at reservoir bottom. Container location at the water body surface is ensured by the floats.

EFFECT: technical result: avoiding the risk of ingress of sea water into a vessel with fresh water, high degree of warming the air above the surface of the path, which intensifies the process of condensation of fresh water.
