Description

The The invention relates to a device for recovering water atmospheric Air according to the preamble of claim 1.

At many places on earth, especially in semi-arid or arid areas such as. in parts of Israel, Egypt, the Sahel or numerous hot deserts, which in a clear Distance to the sea are, at least throughout the year no drinking water supplies available. In addition to the transport of drinking water here is only the possibility of this from humid air.

In many ways, condensers for obtaining condensable water from atmospheric air with a coolable cold storage already known, the relatively humid atmospheric air is cooled below the dew point (see, DE-PS 28 10 241, DD 285 142 A5 ).

In addition, devices are also known which bind by means of an adsorptive or absorptive material such as a salt, for example sodium chloride, or the like atmospheric water in an absorption phase. Here, the salt or the corresponding brine solution is generally stored in a liquid container, wherein the water level or viewed in the vertical direction upper side of the salt or brine is to be regarded as water adsorbing or absorbing surface. In a desorption phase, this salt-water solution or brine is dehumidified to recover the drinking water and the salt is again made available for absorption (cf., for example, DE-PS 2 660 068, US Pat. DE 198 50 557 A1 ).

Furthermore, from the DE 10 2004 026 334 Already a device known, the guide elements, in particular as a bead formed guide element disclosed, wherein the brine solution flows along the guide elements by means of gravity from top to bottom. Dis is an extremely innovative measure to significantly improve absorption and adsorption. Here are also baffles disclosed that collect the wind or the atmospheric air and the absorption or adsorption path or the guide elements perform.

adversely In this case, however, that the absorption or adsorption only can be realized in cross-flow operation. The wind blows in essence horizontally and the brine flows essentially vertically down.

task the invention it is in contrast, a Apparatus for recovering water from atmospheric air with a flowable adsorbent Absorbent, in particular a brine solution with a hygroscopic Salt, for adsorption or absorption of water, at least along an adsorption or absorption path adsorption or absorption provided and wherein at least one Windleitvorrichtung for guiding the Wind to the absorption line is provided to propose the improved the state of the art.

These Task is, starting from a device of the introduction mentioned Art, by the characterizing features of claims 1 or 7 solved. By in the subclaims mentioned measures are advantageous embodiments and further developments of the invention possible.

Accordingly a device according to the invention is characterized in particular characterized in that the wind deflector at least a Trombenerzeuger for generating a rotating about an axis of rotation Whirlwind or air column comprises.

in the Related to atmospheric, in particular moving air generally becomes basically under trunks spatially tight understood limited vortices or whirlwinds or storms of different size and strength, consisting of an air column rotating about a vertical axis.

According to the invention can a more or less permeable housing to the air column or the whirlwind may or may not be present. Preferably a housing present, which has vanes that the formation of the whirlwind promote. Advantageously, these are adjustable, in particular rotatable educated. Hereby, at least in sections, a nearly closed housing be realized, especially on the leeward side or in the lee.

With a Trombenerzeuger invention is achieved that the essentially horizontally oriented wind without big ones Expense by e.g. deflected about 90 ° can be.

Preferably, the wind or the atmospheric air is deflected in such a way that it flows substantially vertically. With this variant of the invention, a direct current or countercurrent principle with respect to the absorbent or the adsorbent or the brine solution and the air or the wind can be realized in an advantageous manner. Hiwerduch ver In particular, the yield of recoverable water improves considerably.

Just With the production of a trombone is achieved that the diversion is particularly compact feasible. In addition, it is achieved that an adaptation to the different occurring wind directions without a big one Effort is realizable.

alternative or in combination with this is a wind energy unit or a Wind turbine provided, preferably as a tangential converter is trained. As a result, for example, the reactor or the absorption or Adsorptionstrecke inside the converter to be ordered. this makes possible a particularly compact unit with a relatively large wind-relevant area.

Farther the reactor can be used as a support unit and / or Carrying unit of the converter can be used twice. This reduces the design effort. In addition, relatively large torques or Lever realized, which improves the energy yield.

For example The generated mechanical and / or electrical energy is pumped the brine solution, a fan or fan or the like is used.

One embodiment The invention is illustrated in the drawing and is based on the Figures in more detail below explained.

In 1 schematically a device according to the invention is shown in the side view. This includes a reactor 1 with the absorption or absorption section and with very schematically illustrated "pearl strings" 2 according to the DE 10 2004 026 334 ,

The reactor 1 is from one to a rotation axis 5 rotating tangential converter 3 jacketed. This includes Windlammelen 4 , For illustration 4 one transverse to the axis of rotation 5 Cut and 7 a schematic plan view. The converter is stored 3 above by means of a bearing 6 and below by means of a support bearing 7 , which is conducted on the reactor jacket.

Optionally, the slats 4 rotatable or adjustable, for example, to allow adaptation to the wind force or possibly to produce a nearly closed shell, for example, in a sandstorm.

A sail 8th covers the lee side or the leeward side.

The sail extends vertically over the converter 3 especially down. At the lower portion of the device according to the invention is a Trombenerzeuger 10 arranged a whirlwind 9 or a rotating air column 9 generated.
