METHOD AND INSTALLATION FOR EXTRACTION OF WATER FROM AIR WITH HYDRO-ENRICHMENT OF AIR FLOW (EMBODIMENTS) Russian patent published in 2025 - IPC E03B3/28 

FIELD: chemistry; physics.

SUBSTANCE: group of inventions relates to production of fresh water from atmospheric air with hydro-enrichment of air flow. Method consists in the fact that external air is drawn into the adsorption chamber, moisture is adsorbed on the sorbent material, desorption of moisture by means of heating, removal of dried air, moisture condensation, collection and storage of water. Main channel and discharge channel are formed for passage of air flow through adsorption rotor. Outer air is drawn into the main channel and the discharge channel of the adsorption chamber through inlet openings. Outer air is passed through adsorption rotor. Moisture is adsorbed in the main adsorption channel and by rotation of the rotor the adsorbed moisture is transferred to the unloading channel. Outside air is heated when drawn into the discharge channel. Heated air is passed through adsorption rotor. Heated air is enriched with moisture adsorbed on the adsorption rotor in the main channel, and the hydro-enriched and heated air flow from the unloading channel of the adsorption chamber is directed into the mixing chamber, into which outside air is drawn in and outside air and heated air enriched with moisture are mixed. Then mixed air flow is directed into condensation chamber for extraction of water from air. Process of drawing in external air and withdrawing dried air, adsorption of air, enrichment, mixing of air flows, condensation and extraction of water from the hydro-enriched air flow is carried out continuously. When moisture content of external air increases to 15 g/m³, external air is drawn into condensation chamber through mixing chamber with closed inlet openings. In compliance with first embodiment, proposed plant comprises adsorption chamber, condensation chamber, heater, heat exchanger, exhaust fan and water collector. In compliance with first embodiment, plant is additionally equipped with main channel and discharge channel, adsorption rotor, first inlet opening, second inlet opening, first outlet opening, a first exhaust fan, a second outlet window and a second exhaust fan, a mixing chamber with a flap for controlling the intake of external air into the mixing chamber, set of environmental parameters metering devices installed outside the adsorption chamber. Heating device for heating of external air is a radiator located in front of the adsorption rotor in the discharge channel. In compliance with second embodiment, proposed plant comprises adsorption chamber, condensation chamber, heater, heat exchanger, exhaust fan and water collector. According to the second embodiment, the plant is additionally equipped with a main channel and an unloading channel, an adsorption rotor, a first inlet window, a second inlet window, a first outlet window, Second outlet opening, mixing chamber with damper to adjust ambient air intake into mixing chamber, set of ambient parameters metering devices arranged outside the adsorption chamber. Heating device is a cylindrical heat energy accumulator, and the heat exchange device is in the form of an anti-gravity heat pipe. In compliance with second embodiment, plant is additionally equipped with first and second air ducts, first air blower, second air blower, solar module and solar radiation concentrator.
