Description

The invention relates to the field of ecology and energy, in particular to the production of fresh water from atmospheric air and the generation of electricity.

A device for producing water from atmospheric air (RF patent for the invention No. 2290480, IPC EV 3/28, B01D 5/00, publ. 12/27/2006), containing an air chamber, the upper wall of which is made of water-absorbing hydrophobic material and an air pump for creating vacuum in the air chamber. Water vapor from the air is absorbed by a hydrophobic plate, water is poured from it to the bottom of the air chamber.

The disadvantages of this device are its low productivity for water and electricity consumption by an air pump.

The well-known energy tower operating on the Maysotsenko cycle with indirectly evaporative air cooling (http://sssrregion.ru/pics/Khalatov_Ukraina.pdf, A. Khalatov, I. Karp, B. Isakov. Maysotsenko cycle and prospects for its use in Ukraine) . It consists of two vertical concentric cylinders. The outer surface of the inner cylinder is covered with a thin layer of a hydrophobic capillary-porous surface wetted by water. Atmospheric air enters the inner cylinder - a dry channel, where it moves downward, being cooled from the cold wall of the channel, the temperature of which decreases due to the evaporation of water from the capillary-porous surface on the outside of the inner cylinder. The cold air emerging from it enters the annular wet channel and moves upward with an increase in its humidity due to the evaporation of water at the outlet of the wet channel. Due to the evaporation of water in the annular wet channel, the mass of the air stream at the outlet of the wet channel is greater than its mass at the entrance to the dry channel. The lowest air temperature close to the dew point is achieved in the lower part of the tower at the outlet of the dry channel. Due to humidification of the air in the wet channel, its pressure decreases and a lifting force arises, which provides air movement through the dry and wet channels with an increase in its speed. The kinetic energy of the air flow is used to generate electricity by a wind generator installed in the lower part of the dry channel.

The disadvantage of the described installation, adopted as a prototype of the invention, is the non-use in it of the extraction of moisture from atmospheric air and insufficient generation of electricity.

The aim of the invention is to obtain a device for extracting moisture from atmospheric air and increasing the generation of electricity. This goal is achieved due to the fact that the device, including two concentrically arranged vertical cylinders forming a "dry" and "wet" air channels, the "wet" channel is equipped with a hydrophobic capillary-porous surface wetted by water, a wind power installation, characterized in that " a wet "channel is located in the inner vertical cylinder, and a hydrophobic capillary-porous surface is attached to the inner wall of the inner cylinder, and a concentric" dry "channel is placed between With the external and internal vertical cylinders, in the lower part of the external cylinder, a water tank is installed to collect condensed moisture, a droplet trap mesh and several rows of moisture drain plates into the water tank with gaps between the plates for air flow passage, while the water tank is connected by an irrigation pipe to the pump with the upper part of the hydrophobic surface, and with the consumer it is connected by a freshwater discharge pipe, movable bearings are installed over the inner vertical cylinder with the help of bearings pus Venturi tube, provided with a wind vane and the central axis of the Venturi tube placed wind power plant with a wind wheel and a generator, wherein the venturi tube body is surrounded by a stationary annular air nozzle, fixed to the inner vertical cylinder.

The invention is illustrated by the following drawings, where:

A device for receiving water from atmospheric air and generating electricity comprises a coaxially mounted external vertical cylinder 7 and an internal vertical cylinder 6, forming a “dry” channel 9 and a “wet” channel 10. The inner surface of the inner vertical cylinder 6 is coated with a hydrophobic capillary-porous surface 8 that is wettable water. In the lower part of the outer vertical cylinder 7 there is a water tank 14 for collecting condensed moisture, a drop catcher 12 and several rows of moisture drain plates 13 with gaps between them for the passage of air flow. The water tank 14 is connected by one pipe 11 to the pump with the upper part of the hydrophobic surface 8, and the second freshwater discharge pipe 15 is connected to the consumer. A movable venturi 3 body, equipped with an air vane 1, is mounted on bearings 5 above the inner vertical cylinder 6. The venturi 3 body is surrounded by a fixed annular air nozzle 2 mounted on the inner vertical cylinder 6. A wind turbine 4 with a wind wheel is placed on the central axis of the venturi 3 and an electric generator.

A device for receiving water from atmospheric air and generating electricity works as follows. Atmospheric air enters the outer vertical cylinder 7 and moves downward through the “dry” channel 9, cooling due to contact with the cold wall of the inner vertical cylinder 6 of the “wet” channel 10. Due to the evaporation of water from the hydrophobic capillary-porous surface 8 covering the inner side of the inner cylinder 6, the temperature in the lower part of its cold wall decreases to a temperature close to the dew point temperature. In this case, condensation of moisture vapor contained in the atmospheric air occurs, droplets of condensate of these vapor are collected on a drip trap 12, and condensate stream flows through the moisture drain plates 13 to a water tank 14. A smaller part of this condensate is pumped through a pipe 11 to the upper part of the hydrophobic surface 8 for wetting it with water, and most of the condensate from the water tank 14 is fed to the consumer through a second condensed fresh water discharge pipe 15. The flowing moisture drain plate 13 is cooled yx is rotated and moves up the "wet" channel 10. Due to the evaporation of water in humid air from the hydrophobic capillary-porous surface 8 covering the inside of the inner vertical cylinder 6 and the relative humidity approaches 100%. In this case, when the humidified air moves through the “wet” channel 10, its mass increases and its density decreases. Therefore, the pressure of the moist air at the outlet of the “wet” channel 10 becomes lower than the pressure of atmospheric air, which increases the vacuum in the narrow section of the venturi 3. The increasing difference in the density of atmospheric air at the entrance to the annular air nozzle 2 and in the narrow section of the venturi 3 provides an increase in the air flow rate in the “dry” 9 and wet 10 channels, and also leads to an additional acceleration of the air velocity in the Venturi 3 pipe and to an increase in the generation of electricity by a wind power generator 4 cal installation.

Compared with the prototype, the proposed device allows, with the same dimensions of the coaxial vertical cylinders, to obtain fresh water from water vapor contained in the atmospheric air, to increase the capacity of the wind power installation and generate more electricity. Wherein:

- atmospheric air enters the "dry" concentric channel, located, in contrast to the prototype, between the outer and inner vertical cylinders;

- the wet channel is located inside the inner vertical cylinder, and the hydrophobic capillary-porous surface covers the inner, and not the outer, as in the prototype, side of the inner vertical cylinder;

- the use in the installation of a fixed annular air nozzle and mounted on the bearings of the movable Venturi pipe with a wind power installation located in it allows you to:

используя кинетическую энергию ветрового потока атмосферного воздуха и повышенную разность давлений атмосферного воздуха и влажного воздуха, поступающего в узкое сечение трубы Вентури, увеличить электрическую мощность и выработку электроэнергии в ветроэнергетической установке;

using the kinetic energy of the wind flow of atmospheric air and the increased pressure difference between atmospheric air and moist air entering a narrow section of the venturi, increase the electric power and power generation in the wind power installation;

использовать получаемую в установке из атмосферного воздуха пресную воду как для водоснабжения внешних потребителей, так и для повышения влажности капиллярно-пористой поверхности, покрывающей стенку влажного канала.

use fresh water obtained in the installation from atmospheric air both for water supply to external consumers and for increasing the humidity of the capillary-porous surface covering the wall of the wet channel.
