Description
Procédé de production d'eau potable et- installation pour sa mise en oeuvre.Process for the production of drinking water and installation for its implementation.
Les procédés actuellement connus de production d'eau potable sont basé sur une distillation, sur des procédés de diffusion osmotique ou autres procédés analogues qui tous exigent la mise en oeuvre d'une eau impure, saumâtre ou salée constituant la matière première de départ et qui sont des procédés chers.The currently known processes for producing drinking water are based on distillation, on osmotic diffusion processes or other similar processes which all require the use of impure, brackish or salt water constituting the starting raw material and which are expensive processes.
La présente invention utilise le phénomène connu de la condensation à savoir le fait que lorsqu'un mélange d'un gaz non condensable et d'une vapeur arrive au contact d'une paroi dont la température est inférieure au point de rosée du mélange, il y a formation d'un condensat sur cette paroi. Ce phénomène est déjà utilisé pour la déshumidification industrielle de l'air d'un local, l'air du local plus ou moins chargé en vapeur d'eau étant amené à circuler en contact avec la paroi d'un échangeur parcouru par un fluide froid. Dans toutes les installations de déshumidifica- tion existantes,l'eau de condensation est purement et simplement rejetée à l'égout et est considérée comme un déchet à a éliminer.The present invention uses the known phenomenon of condensation, namely the fact that when a mixture of a non-condensable gas and a vapor comes into contact with a wall whose temperature is below the dew point of the mixture, it there is formation of a condensate on this wall. This phenomenon is already used for industrial dehumidification of the air in a room, the air in the room more or less charged with water vapor being caused to circulate in contact with the wall of an exchanger traversed by a cold fluid. . In all existing dehumidification installations, the condensed water is simply discharged into the sewer and is considered as waste to be eliminated.
La présente invention est basée sur la constatation qu'à contrario des idées reçues et d'une manière surprenante, la vapeur d'eau atmosphérique condensée dans un déshumidifica teur à échangeur réfrigéré peut constituer une source d'eau potable économiquement intéressante, non seulement dans les pays dépourvus d'eau saumatre ou salée mais en général dans tous les pays où se pose le problème de l'eau potable L'eau obtenue par condensation de l'humidité atmosphérique,# la différence des eaux distillées ou purifiées par diffusion osmotique, est très chargée en micro-organismes, en produits minéraux tels que notamment la silice et en gaz dissous tels que le C02 en raison de la concentration dans le volume d'eau condensé des impuretés et autres contenues dans le volume d'air extremement important traité par litre d'eau récupéré.The present invention is based on the observation that, contrary to popular belief and surprisingly, atmospheric water vapor condensed in a dehumidifier with refrigerated exchanger can constitute an economically advantageous source of drinking water, not only in countries without salty or salty water but in general in all countries where the problem of drinking water is posed Water obtained by condensation of atmospheric humidity, # unlike water distilled or purified by osmotic diffusion, is very loaded with micro-organisms, mineral products such as in particular silica and dissolved gases such as C02 due to the concentration in the volume of condensed water of impurities and others contained in the volume of extremely large air treated per liter of water recovered.
Le procédé de production d'eau potable conforme à l'invention est caractérisé en ce que l'on soumet à un processus de purification l'eau de condensation d'un déshumidificateur d'air. Plus précisément le procédé consiste à faire circuler l'air atmosphérique au contact d'une paroi réfrigérée de manière à condenser sur cette paroi l'humidité qu'il contient en contrôlant le débit du fluide réfrigérant et/ou de l'air atmosphérique pour éviter le givrage recueillir l'eau cohdensee, à la filtrer pour en extraire les matières en suspension, à la stériliser et a améliorer ses qualités organo-leptiques par filtration sur un adsorbant tel que du charbon actif.Le procédé conforme à l'invention est ca ractérisé par la combinaison nouvelle de processus connus en eux-mêmes pour donner naissance à un produit, l'eau de condensation, qui est dans l'art antérieur considérée comme un déchet à éliminer d'un processus de déshumidification de l'air d'un local et transformer ce déchet en un produit économiquement utile.The process for producing drinking water in accordance with the invention is characterized in that the condensation water of an air dehumidifier is subjected to a purification process. More precisely, the method consists in circulating the atmospheric air in contact with a refrigerated wall so as to condense on this wall the moisture which it contains by controlling the flow rate of the refrigerant fluid and / or atmospheric air to avoid icing collect the cohdensee water, to filter it to extract the suspended matter, to sterilize it and to improve its organo-leptic qualities by filtration on an adsorbent such as activated carbon. The process according to the invention is ca reacted by the new combination of processes known in themselves to give rise to a product, water of condensation, which is in the prior art considered as a waste to be eliminated from a process of dehumidification of the air of a room and transform this waste into an economically useful product.
Selon une autre caractéristique du procédé l'eau pure obtenue est reminéraliée avant, pendant ou après son stockage.According to another characteristic of the process, the pure water obtained is remineralized before, during or after its storage.
L'installation pour la mise en oeuvre de l'invention est caractérisée par la combinaison nouvelle d'un ensemble de déshumidification de l'air comportant un groupe frigorifique, un échangeur alimenté par ce groupe frigorifique et un ventilateur pour forcer l'air atmosphérique à circuler au contact des parois de l'échangeur, d'un bac de réception de l'eau condensée sur les parois de l'échangeur, d'un filtre mécani- que, d'un dispositif à lit adsorbant, d'un stérilisateur, de moyens pour faire circuler l'eau recueillie dans le bac à travers ces trois derniers dispositifs et d'un réservoir de stockage de l'eau produite.The installation for implementing the invention is characterized by the new combination of an air dehumidification assembly comprising a refrigeration unit, an exchanger supplied by this refrigeration unit and a fan for forcing atmospheric air to circulate in contact with the walls of the exchanger, a tank for receiving condensed water on the walls of the exchanger, a mechanical filter, an adsorbent bed device, a sterilizer, means for circulating the water collected in the tank through these last three devices and a storage tank for the water produced.
Selon une autre caractéristique l'installation comporte un dispositif d'analyse des caractéristiques physico-chimiques de l'eau obtenue contrôlant un dispositif de reminéralisation. According to another characteristic, the installation includes a device for analyzing the physico-chemical characteristics of the water obtained, controlling a remineralization device.
De préférence le filtre mécanique retient au moins les particules d'une granulométrie supérieure à 5 microns, le dispositif à lit adsorbant est un filtre à charbon actif et le stérilisateur est un dispositif connu à rayonnement ultraviolet.Preferably the mechanical filter retains at least particles with a particle size greater than 5 microns, the adsorbent bed device is an activated carbon filter and the sterilizer is a known device with ultraviolet radiation.
D'autres caractéristiques de la présente invention apparai- tront à la lecture de la description d'une installation de production d'eau potable conforme à l'invention et de son fonctionnement, faite ci-après avec référence au dessin ciannexé dans lequel
La figure unique est un plan schématique de
l'installation,
L'ensemble de l'installation est contrôlé par un ordinateur simplifié 1 recevant les informations de différents détecteurs qui seront décrits ci-après et transmettant des ordres aux différents moteurs et autres éléments de l'installation.Other characteristics of the present invention will appear on reading the description of a drinking water production installation according to the invention and its operation, given below with reference to the attached drawing in which
The single figure is a schematic plan of
installation,
The entire installation is controlled by a simplified computer 1 receiving the information from different detectors which will be described below and transmitting orders to the various motors and other elements of the installation.
L'installation comporte un groupe frigorifique 2 entraîné par un moteur 3, groupe qui envoie le fluide réfrigérant dans un serpentin 4 garni d'ailettes au contact desquelles circule, en étant entraîné par une hélice de ventilateur 5 elle-même entrailnée par un moteur 6, l'air atmosphérique qui est renouvelé en permanence et non recyclé comme dans une installation de déshumidification connue.The installation comprises a refrigeration unit 2 driven by a motor 3, group which sends the refrigerant fluid in a coil 4 provided with fins in contact with which circulates, being driven by a fan propeller 5 itself driven by a motor 6 , atmospheric air which is constantly renewed and not recycled as in a known dehumidification installation.
Un détecteur 7 détecte l'apparition d'un givrage du serpentin 4 et transmet un signal à l'ordinateur 1 qui coupe l'alimentation du moteur 3 lequel est remis en route après fonte du givre. Sous les ailettes du serpentin 4 est placé un bassin 8 de récupération de l'eau de condensation. Ce bassin comporte de préférence des détecteurs de niveau haut et bas 9 qui contrôlent l'alimentation d'un moteur 10 entraînant une pompe Il qui reprend l'eau du bassin 8 pour l'envoyer dans le système de purification décrit ci-après.A detector 7 detects the appearance of an icing of the coil 4 and transmits a signal to the computer 1 which cuts the power to the motor 3 which is restarted after the frost has melted. Under the fins of the coil 4 is placed a basin 8 for recovering the condensation water. This basin preferably comprises high and low level detectors 9 which control the supply of a motor 10 driving a pump II which takes up the water from the basin 8 to send it to the purification system described below.
Le système de purification comporte un filtre-12 qui,de pré férence,combine un filtre coton-silex susceptible de retenir au moins les matières minérales ayant une granulométrie supé- rieure à 5 microns et un filtre adsorbant à charbon actif. Le colmatage du filtre est détecté par la chute de pression entre deux manomètres d'entrée et de sortie 13, le filtre 12 étant changé ou permuté avec un autre filtre lors du colmatage. L'eau filtre passe ensuite dans un stérilisateur à rayonnement ultra-violet 14 avant d'être envoyée dans un réservoir de stockage 15 comportant au moins un détecteur de niveau haut 16 qui arrête l'installation.The purification system comprises a filter-12 which, preferably, combines a cotton-flint filter capable of retaining at least the mineral matters having a particle size greater than 5 microns and an adsorbent filter with activated carbon. The clogging of the filter is detected by the pressure drop between two inlet and outlet pressure gauges 13, the filter 12 being changed or swapped with another filter during clogging. The filter water then passes through a sterilizer with ultraviolet radiation 14 before being sent to a storage tank 15 comprising at least one high level detector 16 which stops the installation.
Un moteur 17 entraîne une pompe de reprise 18 qui envoie l'eau dans un débitmètre 19 qui peut également mesurer les caractéristiques physico-chimiques de l'eau et le résultat de ces mesures est utilisé pour contrôler les moteurs 20 de pompes doseuses 21 qui introduisent dans la canalisation d'eau les produits destinés à reminéraliser l'eau. 22 désigne un robinet de contrôle du débit. A motor 17 drives a recovery pump 18 which sends the water into a flow meter 19 which can also measure the physico-chemical characteristics of the water and the result of these measurements is used to control the motors 20 of metering pumps 21 which introduce products intended to remineralize water in the water pipe. 22 designates a flow control valve.
Le rendement énergétique de l'installation peut être accru en récupérant les calories dans la mesure où elles sont utilisables. The energy efficiency of the installation can be increased by recovering calories as long as they are usable.
Le mode de réalisation ci-dessus décrit à titre d'exemple est susceptible de recevoir de nombreuses modifications.The embodiment described above by way of example is capable of receiving numerous modifications.
C'est ainsi notamment que la circulation de l'eau peut être assurée par gravité sur tout ou partie de la longueur de l'installation, le dispositif de stérilisation peut être du type a injection de produits stérilisants, le dispositif reminéralisateur peut fonctionner par injection d'un mélange prédosé, etc. Pour lutter contre le givrage de l'échangeur, un capteur de type chrono-thermostat peut aussi, dès détection d'un début de givrage, commander une injection de gaz chaud dans l'évaporateur pendant un laps de temps adéquat, et réenclencher le cycle normal aussitôt après. En outre, pour éviter des appels d'intensité trop importants au démarrage électrique du compresseur, un système de by-pass peut y être adjoint et être commandé par un temporisateur, de manière à retarder la compression. Thus, in particular that the circulation of water can be ensured by gravity over all or part of the length of the installation, the sterilization device can be of the type with injection of sterilizing products, the remineralizing device can operate by injection. a predosed mixture, etc. To combat the icing of the exchanger, a chrono-thermostat type sensor can also, upon detection of the beginning of icing, order an injection of hot gas into the evaporator for an adequate period of time, and restart the cycle. normal immediately after. In addition, to avoid excessive intensity calls at the electrical start of the compressor, a bypass system can be added to it and be controlled by a timer, so as to delay compression.
