Abstract

The apparatus uses a centrifugal pump (1) to create cavitation and disperse the CO2 fed into its section side in fine bubbles which dissolve immediately into the water as it passes into a tank (2) where it is homogenized. The amount of CO2 injected is controlled by the volume of water, which is monitored by a meter (3) with an emitting head connected to timers (5, 7), and a gas flow meter (6).

Description

La présente invention concerne un dispositif permettant la dissolution du gaz carbonique dans l'eau. The present invention relates to a device for dissolving carbon dioxide in water.

Le gaz carbonique (C02)est fréquemment utilisé pour acidifier l'eau utilisée dans certaines applications industrielles ou agricoles. Cet abaissement du<B>pH.</B> évite certains inconvénients dus<B>à</B> la présence de calcaire dans la plupart des eaux naturelles: incrustations, alcalinité trop élevée des eaux de boisson en élevage, etc. Carbon dioxide (CO2) is frequently used to acidify water used in certain industrial or agricultural applications. This lowering of <B> pH. </ B> avoids certain disadvantages due to the presence of limestone in most natural waters: incrustations, too high alkalinity of drinking water in livestock, and so on.

Le dispositif, objet de la présente invention, pen-net de dissoudre du<B>C02</B> dans ]'eau, tout en dosant sa concentration avec précision, Pour dissoudre éfficacernent du<B>C02</B> dans l'eau,<B>il</B> faut obtenir un bon contact entre les 2 phases, liquide et gazeuse. La dispersion du gaz petit être obtenue par une forte perte de charge locale dans le circuit, un venturi, les chicanes d'une chambre de contact, etc. The device, object of the present invention, pen-net to dissolve <B> CO 2 </ B> in water, while dosing its concentration with precision, To dissolve effec <B> C02 </ B> in the water, <B> it </ B> must get a good contact between the two phases, liquid and gaseous. The dispersion of the gas can be obtained by a large local pressure drop in the circuit, a venturi, the baffles of a contact chamber, etc.

Dans le dispositif décrit ici, le gaz est dispersé dans le liquide par une pompe centrifuge qui assure en même temps l'homogénéité du mélange sortant de l'appareil. Le gaz est injecté<B>à</B> l'aspiration de la pompe<B>1</B> ce qui provoque une cavitation le dispersant en très fines bulles entraînant sa dissolution immédiate.La pompe refoule l'eau ainsi chargée en<B>C02</B> dans le réservoir d'homogénéisation 2 d'ou elle part vers le circuit d'utilisation. In the device described here, the gas is dispersed in the liquid by a centrifugal pump which ensures at the same time the homogeneity of the mixture leaving the apparatus. The gas is injected <B> to </ B> the suction of the pump <B> 1 </ B> which causes a cavitation dispersant in very fine bubbles causing its immediate dissolution. The pump discharges the water so charged in <B> C02 </ B> in the homogenization tank 2 where it goes to the circuit of use.

La quantité de<B>C02</B> injecté est asservie au volume d'eau<B>à</B> traiter grâce<B>à</B> un compteur d'eau<B>à</B> tête émettrice<B>3</B> qui, en ferrnant un contact électrique tous les<B>5</B> litres par exemple, déclenche l'ouverture de Vélectrovanne 4 qui permet l'injection du<B>C02</B> stocké sous pression dans un réservoir. La durée de cette injection est déten-ninée par le temporisateur<B>5</B> dont le règlage permet ainsi de quantifier le volume de gaz admis<B>à</B> chaque impulsion, le débit du gaz étant mesuré par le débimètre <B>6.</B> La ferrneture du contact du compteur met également en route la pompe<B>1,</B> mais pour éviter son fonctionnement en It courts cycles" un deuxième temporisateur<B>7</B> n'en provoque l'arrêt qu'après 2 minutes,par exemple, après la dernière impulsion.The amount of <B> C02 </ B> injected is slaved to the volume of water <B> to </ B> treated by <B> to </ B> a water meter <B> to </ B> transmitting head <B> 3 </ B> which, by ferreting an electrical contact every <B> 5 </ B> liters for example, triggers the opening of solenoid valve 4 which allows the injection of <B> C02 </ B> stored under pressure in a tank. The duration of this injection is held by the timer <B> 5 </ B> whose adjustment allows to quantify the volume of gas admitted <B> to </ B> each pulse, the gas flow rate being measured by the flowmeter <B> 6. </ B> The ferrneture of the contact of the meter also starts the pump <B> 1, </ B> but to avoid its operation in It short cycles "a second timer <B> 7 < / B> stops it only after 2 minutes, for example after the last pulse.
