RU2823316C1 - Device for obtaining fresh water from atmospheric air in areas with high tide intensity - Google Patents

Abstract

FIELD: methods and apparatus for producing or collecting water.

SUBSTANCE: invention relates to devices for producing fresh water from water vapours contained in ambient air, and can be used to produce fresh water mainly in coastal areas with high tide intensity. Device consists of a pool filled with sea water at high tide, in the lower part of which there are weirs closed by doors. Shields are installed to the side surface of the pool along its perimeter in the immediate vicinity of the weirs and above them with the help of fasteners. Shields are fixed on the side surface of the pool from its outer side so that they can be pulled out during low tide and located at angle of 100 to 150 degrees relative to the vertical plane with rigid fixation, and move in until it touches the outer side surface of the pool when the pool is filled with sea water at high tide. Ends of shields in extended state are in free state above reservoir for collection of fresh water. Pool is fenced along the entire side and upper surface with a fine-mesh structure spaced from the side and upper surface of the pool at distance of 1 to 1.5 meters, which is fixed on supports made in the form of pillars having a height greater than the height of the pool, and installed along its perimeter.

EFFECT: reducing the area occupied by shields when filling the pool with sea water, as well as eliminating the negative effect of the device during operation on the state of coastal flora and fauna.

Description

The invention relates to devices for obtaining fresh water from water vapor contained in the surrounding atmospheric air, and can be used to obtain fresh water mainly in coastal areas with high tides and low tides.

The prototype of the invention is the device described in [1].

The device contains a cooled partition separating the condensation zone of water vapor and cooling water. The cooled partition is made in the form of shields fixed around the perimeter of the pool, which is filled with sea water during high tide and emptied during low tide. The pool is equipped in the lower part with spillways with opening and closing doors so that their ends, opposite the fixed ones, are in a free state above the container for collecting fresh water.

The disadvantage of the device is that the shields occupy a fairly large area and prevent any objects from being located or moving near the pool. Another disadvantage of the device is the negative impact on coastal flora and fauna, since at the moment of high tide and the pool is filled with seawater, both living organisms (fish, shellfish, crustaceans, corals, etc.) and marine vegetation (phytoplankton, seaweed) can get there etc.), which can lead to their death.

The technical result of the invention is to reduce the area occupied by the shields when filling the pool with sea water, as well as to eliminate the negative impact of the device during its operation on the state of coastal flora and fauna.

The technical result is achieved by the fact that the shields are fixed so that they can be pulled out during low tide and positioned at an angle of 100 to 150 degrees relative to the vertical plane with rigid fixation, and moved in until they come into contact with the outer side surface of the pool when the pool is filled with sea water at high tide. The pool is fenced along the entire side and top surface with a fine-mesh mesh structure, spaced from the side and top surface of the pool at a distance of 1 to 1.5 meters, mounted on supports made in the form of pillars having a height greater than the height of the pool and installed along its perimeter.

The design of the device is shown in Fig. 1.

The device consists of a pool 1, filled with sea water during high tide, in the lower part of which there are spillways 2, initially closed with special doors 3. To the side surface of the pool 1 along its perimeter in the immediate vicinity of the spillways 2 and above them using fastening devices 4, shields 5 are installed. Shields 5 are fixed on the side surface of the pool 1 from its outer side so that they can be pulled out during low tide and positioned at an angle of 100 to 150 degrees relative to the vertical plane with rigid fixation, and moved in until they come into contact with the outer the side surface of the pool while filling pool 1 with seawater at high tide. The ends of the shields 5 in the extended state are in a free state above the container for collecting fresh water 6. The pool 1 is fenced along the entire side and top surface with a fine mesh structure 7, spaced from the side and top surface of the pool at a distance of 1 to 1.5 meters, attached on supports 8, made in the form of pillars having a height greater than the height of the pool 1 and installed along its perimeter.

The device works as follows. At high tide, pool 1 is filled with seawater at a temperature below ambient temperature, which is typical for almost all regions in the summer. In this case, the spillways 2 are in their original position (closed by doors 3). After low tide, when the level of sea water outside the pool is significantly lower than the level of the spillways 2 doors 3 open - the outflow of sea water into the environment begins. The cold sea water flowing through the weirs 2 will cool the extended shields 5, thereby creating a condensation zone on their upper surface. Due to their inclination, the moisture condensed on this surface of the shields 5 will flow into the fresh water collection container 6, from where it will be removed for further use before the next tide. Folding the panels 5 during the process of filling the pool 1 with sea water will reduce the area occupied by the structure. A fine mesh structure 7 enclosing the pool 1 with the help of supports 8 limits the entry of representatives of coastal flora and fauna into the pool during high tide.
