AUTONOMOUS ATMOSPHERIC MOISTURE EXTRACTOR Russian patent published in 2021 - IPC E03B3/28 

FIELD: fresh water producing devices.

SUBSTANCE: invention relates to the field of devices for producing fresh water from atmospheric air using renewable energy sources. Autonomous extractor of atmospheric moisture consists of a vertical-axial wind turbine in the form of an inlet vortex ejector, a collector with condensed moisture. The device additionally contains a vortex cooler, a condensation chamber, a radiator-heat exchanger for air cooling. The vertical-axial wind turbine is made in the form of an inlet vortex ejector designed to form a swirling laminarized air flow and pump it through an air duct into a vortex cooler, where the air flow is divided into hot and cold streams. The vortex cooler has one air duct for supplying the hot flow to the radiator-heat exchanger of the condensation chamber, and the other air duct also supplies cooled air to the radiator-heat exchanger of the condensation chamber. The moisture condensed in the radiator-heat exchanger enters the water collector, where the cold accumulator is installed, made of a composite material with low thermal conductivity. A condensation chamber with a vortex cooler, an air-cooling radiator and a water collector located in it is installed under the fill mound above the ground line. In the vortex inlet ejector, the vortex generator modules are located one above the other, and the inner radii of each module, starting from the upper one, are reduced by 10% and are set so that the air flow oncoming at a speed of 2 to 20 m/s passing through the air intake of each vortex module ejector, forms its swirling laminarized flow in the form of thin-walled air cylinders that do not mix with each other and are pumped through the air duct into the vortex cooler. In a vortex cooler, the flow is split, forming a hot air stream enriched with moisture and a cooled stream that enters the radiator-heat exchanger for cooling. Saturated hot air enters the condensation chamber, where it condenses on cooled radiators, and then the condensed moisture enters the water collector, where an additional cold accumulator is a block made of composite material with low thermal conductivity. The air dehumidified from moisture and cold air from the extraction chamber are discharged through the exhaust air ducts into the exhaust vortex ejector, and then into the environment. A water collector with a moisture condenser is installed under the embankment above the ground line. The exhaust vortex ejector is structurally similar to the inlet vortex ejector of atmospheric air.

EFFECT: invention increases efficiency of extraction of fresh water from atmospheric air.
