Abstract

Sea water is pumped up into tanks. It is filtered to reduce the salt content. It is cooled (sic) progressively as required for use. An Independent claim is included for corresponding equipment, sized for domestic use.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

Les appareils de désalinisation, utilisant la chaleur et l'évaporation, comme moyens, sont connus.  Desalination apparatuses, using heat and evaporation, as means, are known.

La présente proposition vise à produire de l'eau douce, à partir d'eau de mer, par le biais de la congélation.  The purpose of this proposal is to produce fresh water from sea water by freezing.

L'eau, élément vital pour l'homme, quel que soit son état : gazeux, liquide ou solide, devient une préoccupation écologique fondamentale.  Water, a vital element for man, whatever its state: gas, liquid or solid, becomes a fundamental ecological concern.

Le réchauffement de la planète et les sécheresses en résultant, la pollution des nappes phréatiques par les effluent industriels ou les traitements agricoles font craindre des difficultés d'approvisionnement en eau saine.  Global warming and the resulting droughts, pollution of groundwater by industrial effluent or agricultural treatments raise fears of problems with the supply of clean water.

Le présent procédé a pour ambition de répondre à d'éventuelles pénuries en eau, grâce à des installations simples, permettant les phases opératoires suivantes : - Pompage et transport par canalisation

Figure img00010001

- Stockage en bacs, - Filtrage afin de réduire le taux de sel - Transport par canalisations dans une centrale de répartition, en différents récipients de taille moyenne, - Roulage de ces bacs dans des chambres de congélation L'action du froid, produit par congélation ou par utilisation d'azote liquide, permet le détachement des molécules d'eau douce et leur reconstitution sous forme blocs de glace. The present process aims to respond to possible water shortages, thanks to simple installations, allowing the following operational phases: - Pumping and transport by pipeline
Figure img00010001

- Storage in tanks, - Filtering in order to reduce the salt rate - Transport by pipes in a distribution center, in different medium-sized containers, - Rolling of these tanks in freezing chambers The action of cold, produced by freezing or by using liquid nitrogen, allows the detachment of freshwater molecules and their reconstitution in the form of ice blocks.

Les blocs obtenus sont stockés après démoulage dans des réservoirs en vue de leur fonte.  The blocks obtained are stored after demoulding in tanks for melting.

Cette réflexion peut être poursuivie en vue de miniaturiser le dispositif permettant éventuellement de créer une méthode de désalinisation à usage domestique. This reflection can be continued with a view to miniaturizing the device, possibly making it possible to create a desalination method for domestic use.
