Abstract

FIELD: water treatment.

SUBSTANCE: invention relates to devices for producing fresh water from water vapours contained in ambient air. Device contains an open-top container immersed into a reservoir with sea water so that its walls extend beyond the water surface. Inside the container there is a through channel for sea water flow, which is located between two opposite walls of the container and arranged so that one end of the channel is located at the water surface, and the other one is below with an inclination within range of 20–45°. Cross-section of the channel has the shape of a triangle, the base of which faces the bottom of the container, and the top faces the surface of the water body. Length of the triangle base is less than the width of the container in the direction perpendicular to the arrangement of the channel. Angle between lateral ribs of triangle is within 90–140°. In the immediate vicinity of the above end of the channel in the sea water there is an actuating mechanism of a wind energy converter, which is a rotating shaft with a blade mechanism for injecting sea water into a channel fixed from the outside to the side surface of the container by means of a fastening device. Container is located at the surface of the water body by floats. From the end of the channel, located at the surface of sea water, there are through branches ending at the opposite wall of the container, which are identical in shape and size to the channel itself, number of which varies from one to three, located at angles of 5, 10 and 15° to its lower surface, respectively.

EFFECT: increased area of condensation of the device and increased volume of produced fresh water.

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 seas.

The prototype of the invention is the device described in [1]. The device contains a container with an open top, immersed in a body of sea water so that its walls extend beyond the surface of the water. Inside the container there is a through path for the flow of sea water, located between two opposite walls of the container and placed so that one end of the path is at the surface of the water, and the other is lower with an inclination in the range of 20-45°. The tract in cross section has the shape of a triangle, the base of which faces the bottom of the container, and the apex faces the surface of the reservoir, and the length of the base of the triangle is less than the width of the container in the direction perpendicular to the placement of the tract, and the angle between the side edges of the triangle lies in the range of 90-140°. In the immediate vicinity of the upper end of the path in sea water there is an actuator of the wind energy converter, which is a rotating shaft with a blade mechanism for pumping sea water into the path, fixed externally to the side surface of the container due to a fastening device. The location of the container at the surface of the reservoir is ensured by floats.

The disadvantage of such a device is the insufficient condensation surface area, which limits the production of a large volume of fresh water.

The purpose of the invention is to increase the condensation area of the device and increase the volume of fresh water produced.

The goal is achieved by the fact that from the end of the tract, located at the surface of sea water, there are through branches ending at the opposite wall of the container, identical in shape and size to the tract itself, the number of which varies from one to three. Through branches are located at angles of 5, 10 and 15 degrees, respectively, to the lower surface of the tract.

The block diagram of the device is shown in Fig. 1.

The device consists of a container 1 with an open top, immersed in a reservoir of sea water so that its walls extend beyond the surface of the water and prevent splashes from its waves from entering the container 1. Inside the container 1 there is a through path 2 for the flow of sea water, located between two opposite walls of the container 1 and placed so that one end of the path is at the surface of the water, and the other below with an inclination in the range of 20-45°. The path is shown in Fig. 2 and in cross section has the shape of a triangle, the base 3 of which faces the bottom of the container 1, and the top 4 faces the surface of the reservoir. The length of the base of the triangle is less than the width of the container 1 in the direction perpendicular to the placement of the tract 2. The angle between the side ribs 5 of the triangle lies in the range of 90-140°. In the immediate vicinity of the upper end of path 2 in sea water there is an actuator of the wind energy converter 6, which is a rotating shaft with a blade mechanism for pumping sea water into path 2. The wind energy converter 6 is attached externally to the side surface of the tank 1 due to a fastening device 7. At the bottom of container 1 there is a vessel for fresh water 8. The location of container 1 at the surface of the reservoir is ensured by floats (not shown in the figures). From the end of path 2, located at the surface of sea water, there are through branches 9, ending at the opposite wall of the tank, identical in shape and size to the path itself, the number of which varies from one to three. Through branches 9 are located at angles of 5, 10 and 15 degrees, respectively, to the lower surface of the tract.

Container 1 is placed in the reservoir and fixed in the required position using appropriate clamps (not shown in the figures). After container 1 is immersed in the reservoir, sea water will begin to flow through path 2 and its through branches 9 due to their tilt at the appropriate angle under the influence of gravitational forces. Sea water will cool path 2 and its through branches 9 in general and in particular their upper surface, thereby forming a moisture condensation zone. The continuous movement of sea water along path 2 and its through branches 9 is carried out by a wind energy converter 6, ensuring its constant injection into path 2 and its through branches 9 from the side located near the surface of the reservoir. Moisture condensed from the air will flow into a vessel for collecting fresh water 8 due to the action of gravitational forces and the special design of tract 2 and its through branches 9, in cross-section having the shape of a triangle with a base 3, apex 4 and side ribs 5, inclined relative to horizontal axis. Floats ensure that container 1 is always located at the surface of the reservoir. The volume of fresh water produced is increased by increasing the condensation surface area.
