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. Purpose of the invention is to increase the efficiency of using the thermal potential of sea water, as well as increase the useful operating time of the device. Device consists of a pool filled with sea water at high tide, in the lower part of which there are weirs initially closed by doors. To the side surface of the pool along its perimeter in the immediate vicinity of the weirs and above them, shields are installed at an inclination by means of fasteners so that their ends, opposite to the fixed ones, are in a free state above the tank for collection of fresh water. Shields made in the form of two planes forming a dihedral angle in range of 90° up to 160°, act as a cooled partition separating the condensation zone of water vapor and cooling water. Discharge of condensed fresh water from the condensation zone is carried out into the tank for collecting fresh water. In order to impart strength of attachment of shields, supports are additionally provided in their central part, which are dug into the ground. Shields on sides have limiting surfaces from low-heat-conductivity material, which prevent leakage of sea water beyond the limits of water conduits formed by them, shields and surface of the earth. Weirs are equipped with pressure regulators of the outflowing sea water.

EFFECT: higher efficiency of use of thermal potential of sea water, as well as increase in effective operating time of the device.

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, wherein the cooled partition is made in the form of shields fixed around the perimeter and located at an angle in the direction from the pool, 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. To provide strength to the fastening of the shields, additional supports are provided in their central part, dug into the ground, and the ends of the shields attached to the pool are located in close proximity to the spillways.

The disadvantage of the device is that when cooling the shields with sea water, only part of its thermal potential is used, since when the pool is emptied, sea water flows from the weirs not only under the shields, but also to the sides of them. In addition, the high flow rate of sea water reduces the useful operating time of the device (the time it takes to obtain fresh water) by accelerating the process of emptying the pool.

The purpose of the invention is to increase the efficiency of using the thermal potential of sea water, as well as to increase the useful operating time of the device.

The goal is achieved by the fact that all the shields are made in the form of two planes, forming a dihedral angle in the range from 90° to 160°, on the sides they have restrictive surfaces made of low thermal conductivity material that prevent sea water from flowing out beyond the water conduits formed by them, the shields and the surface of the earth. The spillways are equipped with pressure regulators for flowing seawater.

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, the shields 5 are installed at an angle so that their ends, opposite to the fixed ones, are in a free state above the container for collecting fresh water 6. The shields 5, made in the form of two planes forming a dihedral angle in the range from 90° to 160°, carry out the role a cooled partition separating the condensation zone of water vapor and cooling water. The flow of condensed fresh water from the condensation zone is carried out into a container for collecting fresh water 6. To add strength to the fastening of the panels 5, supports 7 are additionally provided in their central part, dug into the ground. The shields 5 on the sides have restrictive surfaces made of low thermal conductivity material that prevent the flow of sea water beyond the limits of the water conduits formed by them, the shields 5 and the surface of the earth. The spillways are equipped with pressure regulators for flowing sea water 8.

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 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. The presence of water conduits formed by shields 5, restrictive surfaces and the surface of the earth will allow more efficient use of the thermal potential of sea water, this is also facilitated by the manufacture of shields 5 in the form of two planes forming a dihedral angle in the range from 90° to 160°, increasing the contact area of shields 5 and sea water. The use of sea water pressure regulators 8 makes it possible to increase the useful operating time of the device.
