METHOD AND DEVICE FOR FRESH WATER EXTRACTION FROM ATMOSPHERIC AIR Russian patent published in 2018 - IPC E03B3/28 

FIELD: machine engineering.

SUBSTANCE: form a stream of atmospheric air and cool the formed airflow by means of a vortex effect. Generate the airflow entering with the speed of 2 to 20 m/s, passing through an air intake (7) of the "vortex generators". A laminarized swirling flow cooled to the dew point is formed at a speed exceeding the initial wind speed by 5 to 7 times, and thereby injecting a single swirling flow of air environment into a water collector filled with a dew condenser in which the fresh water is extracted. Create an exhaust draft with an exhaust "vortex generator" and drain the dried air out of the water collector. The device contains a water collector with a dew condenser and an input and an exhaust "vortex generators". The input "vortex generators" consist of n+1 module located devices to generate the airflow, incoming at a speed from 2 to 20 m/s. Each "vortex generator" is executed in the form of at least two hollow elements (10 and 11) coaxially installed in the device, placed one in another. The lower and the upper hollow elements (10 and 11) are in the form of truncated cone-shaped hyperboloids of rotation. The internal radiuses of each hollow element are referred to as r_lower=⋅ 0.4375r_upper, where r_lower is the radius of the lower element, r_upper is the radius of the upper element. The external radiuses of the elements forming the air intake (7) are referred to as R_ai = 5⋅r_upper, where R_ai is the external radius of the hollow element, r_upper is the radius of the upper element. In the cavity of each hollow element (10 and 11) vertical blade-walls (12) are placed, curved along the spiral of Archimedes, to generate cooled laminarized swirling flow to the dew point in the spiral vortex-forming channels (13). The channels (13) have a spiral shape and taper as they approach the cylindrical channel (14) and form a single cooled swirling flow in the cylindrical channel. The input "vortex generators" are connected by the air ducts to the water collector and inject the cooled air to the dew point into the water collector filled with the dew condenser. The exhaust "vortex generator" pulls the dehumidified air into the environment through the air duct connected to the water collector. The water collector with the dew condenser is placed under a bulkhead above the ground line at a height equal to the depth of soil warming, depending on the climatic conditions of the specific area.

EFFECT: increase the reliability and durability of the device.
