  • the combined desalt-hydroelectric power plant is an electricity power plant that combines the potential energy of water, the deference of pressure between the atmosphere and vacuum and finally the heat reservoir of the atmosphere in order to produce electricity and fresh water.
  • Hydroelectric power plants can guaranty constant production of energy at a very low cost per kWh. Also they do not emit to the environment any green gas so they do not contribute to the global worming of our planet. But this method has some major disadvantages. First, its application is limited to the morphology of the surrounding area. Hydroelectric power plants can be installed only were there is water stored in a lake, natural or artificial. Also it requires the construction of a dam witch is very costly and it alters the morphology of the surrounding area by raising the water level in that area.
  • Power plants using renewable energy sources such as solar, have a major disadvantage. They cannot guarantee stable production because they cannot store the energy efficiently. So when the natural energy source is not available, for example at night production stops.
  • the combined desalt-hydroelectric power plant is a production method of electric energy and fresh water using the energy of gravity to produce electric energy and the atmospheric pressure to elevate water in the form of saturated steam up to the desired height.

  • Heat pump device is installed close to the lower part of the vacuum chamber supplying sufficient heat to the water in order to evaporate.
  • the heat pump device is a close circuit reverse air- condition device well known to the industry. Napor is raised inexpensively, to the desired height, using the pressure deference between the atmospheric pressure, outside the vacuum chamber, and the vacuum inside the vertical vacuum chamber.

So condensed water is supplied in the top of the hydrostatic tube and same quantity of water is leaving the hydrostatic tube in the lower part since the water level inside the hydrostatic tube can not be altered. Then water falls down to the turbine through a pipe to produce work.
  • the above-mentioned combined desalt-hydroelectric power plant combines production of electricity and fresh water using renewable energy sources such as gravitation and deference of pressure between the atmosphere and vacuum and finally the environment as heat source.
  • thermodynamic system witch converts water in to steam in vacuum pressure and vice versa, consuming electric energy produced from the plants generator and extracting / absorbing heat to and from the environment.

Abstract

Cette centrale combinant dessalement et production hydroélectrique est un procédé de production d'électricité et d'eau potable au moyen de sources d'énergies renouvelables. A cet effet, on fait évaporer de l'eau de mer à l'intérieur d'une chambre à vide (5) avec suffisamment de hauteur, à basse température, et on fournit la chaleur requise de façon à évaporer l'eau au moyen du condenseur (4) des pompes à chaleur. La pression atmosphérique appliquée sur la surface des eaux élève la vapeur à l'intérieur de la chambre à vide étant donné que la pression à l'intérieur de la chambre est moins élevée et que la densité de la vapeur est également moins élevée. Lorsque la vapeur atteint la hauteur désirée, elle se condense à l'intérieur du condenseur. L'eau condensée est évacuée à bon compte de la chambre à vide vers l'environnement au moyen du tube hydrostatique (7). L'eau extraite du condenseur est amenée par gravité au moyen d'un tuyau sur une turbine (9) placée moins haut pour produire le travail. Cette centrale convient pour la production d'eau potable et d'électricité sans nécessiter de combustible fossile ou de ressources naturelles telles que les rivières et les lacs.
