Description

The invention relates to a device for obtaining drinking water from the air by condensing the moisture present in the air.

Such solutions for drinking water production are known.

In the DE 33 13 711 A1 a device for drinking water extraction is described in which the air is cooled to below the dew point, so that moisture contained in the air at least partially condenses. For this purpose, a cooling element is used. The water thus obtained is collected and then processed to drinking water quality.

From the DE 34 31 186 A1 It is known to use a honeycomb grid as the condensation surface and to control the process of condensation by processing measurement results from humidity and temperature sensors.

The DE 198 11 274 A1 proposes to carry out the condensation using regenerative energies. Ambient air is drawn in by convection, mixed with mineral particles and passed into a cooling channel. There, the humidity of the mineral particles condenses into water droplets and settles on cooling surfaces in the form of frost. It works with cooling temperatures of -20 °.

A change of cooling and tumble mode then produces water, which is treated to drinking water.

In the DE 198 50 557 A1 the air is condensed on a material having a certain pore structure to allow capillary condensation. In a second phase, this material is heated, so that the water vapor bound in the material emerges and is then converted into water in a subsequent condensation.

A disadvantage of these solutions is that the process implementation requires an energy supply, be it for the condenser cooling, be it for necessary heating processes or for the air supply. It would certainly be possible to cover this energy demand by wind or solar power, but this increases the expenditure on equipment.

The object of the invention is to provide a device for drinking water production, which operates essentially independently and without supply of electrical energy.

This object is achieved with the features of claim 1, advantageous embodiments are the subject of the dependent claims.

According to the invention, in a device for obtaining drinking water from the air, in which parts of the moisture contained in the air are removed by cooling on a condenser, wherein the condenser has an inlet and an exhaust duct and the condensed water is fed to a collecting container, proposed that the condenser and the collecting container are arranged in the depth of a water body, wherein the collecting container is located in greater depth, the inlet opening of the supply air duct and the outlet opening of the exhaust duct above the water level arranged in the opposite direction and the distance of the inlet opening from the water level greater is as the outlet opening.

Thus, the temperature difference between the air and the water is used for the condensation with this device.

In an advantageous embodiment, it is further provided that the condenser, which has condensation sheets, rods and / or channels arranged essentially transversely to the air flow, can be cooled by water introduced from a greater depth.

For cooling the condenser and / or its parts, a water circuit open on both sides to the water is preferably used, wherein the inlet is arranged at a greater depth than the outlet.

Preferably in the inlet channel of the cooling water circuit through the condenser, a suction pump may be additionally installed. In a preferred embodiment, this can be driven by a windmill towering above the water level.

In order to achieve an optimal air flow through the condenser, a further advantageous embodiment provides that
the levels of the inlet opening and / or the outlet opening are arranged perpendicular to the water level or with a deviation of up to 15 ° to the vertical and / or
the inlet channel and / or the outlet channel have a pivotable head part, so that the position of the inlet opening and the outlet opening is variable in a plane parallel to the water level.

The necessary pivoting forces for pivoting the head parts can be achieved by arranged on the head parts wind vanes.

By an appropriate arrangement of these wind vanes can also be achieved that the inlet opening of the inlet channel is always aligned against the wind direction, so that the air is blown directly into the inlet opening. When the exhaust duct, a corresponding wind vane causes the opposite position, so that the air is sucked out of the exhaust duct by the wind.

In a further advantageous embodiment, it is provided that the collecting container, which preferably consists of an elastic material, has a base support and in addition, preferably with ballast bodies, is weighted so that a stable position is ensured on the bottom of the water.

These ballast bodies are preferably arranged detachably on the collecting container.

The own weight of the collecting body, when used in salt water, can be further designed such that it floats with condensed water when the ballast bodies are removed or partially removed and at a predetermined degree of filling.

An embodiment and technical details of the apparatus for obtaining drinking water from the air is shown in the drawings. Show it:

1 the condenser with sump and

2 a coolable capacitor.

1 shows the main components of the device for obtaining drinking water from the air: the condenser 1 with supply air duct 12 and exhaust duct 13 and the collection container 20 for condensed water flowing over the pipe 19 with the capacitor 1 connected is.

The capacitor 1 and the collection container 20 are arranged in the depth of a body of water, the collecting container 20 is in greater depth. The inlet opening 15 of the supply air duct 12 and the outlet opening 16 the exhaust duct 13 are arranged above the water level and point in the opposite direction, wherein the distance of the inlet opening 15 from the water level is greater than that of the outlet opening 16 ,

The inlet channel 12 and the outlet channel 13 each have a pivoting headboard 12a . 13a on, so the location of the inlet opening 15 and the outlet opening 16 in a plane parallel to the water level is changeable.

The levels of the inlet opening 15 and the outlet opening 16 are arranged perpendicular to the water level.

For pivoting the head parts 12a . 13a serve at the headboards arranged wind vanes 17 , The arrangement of the wind vane 17 is done so that the inlet opening 15 of the intake channel 12 Always aligned against the wind direction, allowing the air directly into the inlet opening 15 is blown. At the outlet channel 13 causes a corresponding wind vane 17 the opposite position, allowing the air through the wind from the exhaust duct 13 is sucked out.

The collection container 20 made of an elastic material has a base pad 23 which, along with the ballast bodies 22 ensures a stable position on the bottom of the water.

About the hose 21 can air from the sump 20 escape when it fills with water. The water itself can be over the hose 24 from the collection container 20 pump out.

2 shows in a detailed view of a coolable capacitor 1 , The capacitor 1 , Which has substantially transverse to the air flow arranged condensation sheets, rods and / or channels is cooled by water introduced from greater depth. For this purpose, a water circuit open on both sides to the water is used, whereby the inlet is arranged at a greater depth than the outlet and in the inlet channel 2 a suction pump 3 is installed. The depth of the outlet from the outlet channel 10 is controlled by thermostats. The outlet channel 10 For this purpose, it may have staggered outlet openings in depth which are controlled by thermostats between an open or a closed state. The inlet and the outlet channel 2 . 10 are each with an insulation layer 11 coated or consist of such a material in order to achieve optimum cooling of the capacitor.

The suction pump 3 becomes via a windmill towering over the water level 6 driven.
