L'objet de l'invention est la production d'eau douce à partir de l'eau de mer. Le procédé consiste avec la seule énergie des vagues à comprimer de l'air dans un réservoir (1) ouvert sur la mer, par le bas. La hausse et baisse du niveau de l'eau dans le réservoir (1), provoquée par les vagues agit comme un gigantesque piston et comprime l'air. Puis cet air est détendu dans le réservoir (4) après avoir été saturé d'eau dans le réservoir (3 ). La détente provoque de la pluie d'eau douce dans le réservoir (4).The object of the invention is the production of fresh water from sea water. The method consists with the sole energy of the waves in compressing air in a reservoir (1) open on the sea, by the bottom. The rise and fall of the water level in the tank (1), caused by the waves acts like a gigantic piston and compresses the air. Then this air is expanded in the tank (4) after being saturated with water in the tank (3). The trigger causes rain of fresh water in the tank (4).
L'énergie produite par la mer est immense mais est peu exploitée car très dispersée . La houle monte et descend par vagues avec une fréquence de l'ordre de 100 secondes selon le lieu. L'invention consiste à utiliser ces mouvements de hausse et baisse pour comprimer de l'air dans un réservoir ( 1) et ensuite dans un autre réservoir (4)de provoquer par détente une pluie d'eau douce.The energy produced by the sea is immense but is little exploited because it is very dispersed. The swell rises and falls in waves with a frequency of the order of 100 seconds depending on the location. The invention consists in using these upward and downward movements to compress the air in a tank (1) and then in another tank (4) to cause by relaxation a rain of fresh water.
Pour obtenir un débit continu 1' air qui a été comprimé au rythme des vagues alternativement, dans le réservoir (1) est transféré dans le réservoir tampon (2 ) qui ensuite débite dans le réservoir(3) pour y être saturé par barbotage au passage dans l'eau de mer qui y circule doucement. L'air obtenu ainsi est saturé en vapeur d'eau et à une pression de quelques bars . Quand il est injecté dans le réservoir ( 4) qui est maintenu en dépression par l'aspiration alternative du réservoir ( 5) agissant comme une pompe à air, la chute de pression y provoque une pluie d'eau douce.To obtain a continuous flow, the air which has been compressed alternately with the rhythm of the waves, in the tank (1) is transferred to the buffer tank (2) which then flows into the tank (3) to be saturated there by bubbling in the passage in the sea water which circulates there gently. The air thus obtained is saturated with water vapor and at a pressure of a few bars. When it is injected into the tank (4) which is maintained in depression by the alternative suction of the tank (5) acting as an air pump, the pressure drop causes a rain of fresh water.
L'ouverture de la valve (o) pour Γ entrée d'air à pression ambiante dans la chambre (13) du réservoir ( 1) pour y être comprimé et suivie de ,'ouverture de la valve (9) pour le transfert de cet air une fois comprimé dans le réservoir x tampon (2) sont provoquées par les variations de niveau du flotteur (11).The opening of the valve (o) for Γ entry of air at ambient pressure into the chamber (13) of the tank (1) to be compressed and followed by, 'opening of the valve (9) for the transfer of this Once compressed air in the tank x buffer (2) are caused by variations in the level of the float (11).
Le réservoir (2) est relié par le bas à un autre réservoir (3) où on fait barboter l’air dans le fond de ce réservoir (3) où coule doucement de l'eau de mer salée. Les bulles qui émergent ainsi à la surface de l’eau sont chargées de vapeur en quantité en fonction de la température de l'eau.The tank (2) is connected from below to another tank (3) where the air is bubbled through the bottom of this tank (3) where salt sea water flows gently. The bubbles which thus emerge on the surface of the water are charged with steam in quantity depending on the temperature of the water.
A la partie supérieure de ce réservoir une conduite dirige l'air ainsi chargé d'eau et à une pression de quelques bars vers un réservoir (4) où se produisent la détente et la pluie d'eau douce. Pour que cette détente soit suffisante à partir d'un cinquième réservoir (5) on pompe l'air du réservoir (4) alternativement au rythme des vagues sous commande du flotteur( 11) de ce réservoir( 5).At the upper part of this tank a pipe directs the air thus charged with water and at a pressure of a few bars towards a tank (4) where the expansion and the rain of fresh water occur. For this expansion to be sufficient from a fifth tank (5), the air from the tank (4) is pumped alternately at the rate of the waves under the control of the float (11) of this tank (5).
L'eau douce du réservoir (4) se prélève par la conduite (10).Fresh water from the reservoir (4) is drawn off through the line (10).
