Title (EN) GAS DISSOLVING APPARATUS AND METHOD
(FR) APPAREIL ET PROCEDE DE DISSOLUTION DE GAZ
Abstract: front page image
(EN)An apparatus (10) for dissolving a gas into a fluid which may contain at least one dissolved gas. The apparatus (10) includes a first vertically oriented tube (2) defining a first inner space (32) and a second vertically oriented tube (12). The space between the first and second tubes is referred to as the second inner space (40). The gas is introduced through an inlet (18) into the second inner space (40). The apparatus (10) includes an acceleration device (20) for accelerating the flow of fluid through the second inner space (40). The apparatus includes a helix-shaped bubble harvester (22) which removes fugitive (undissolved) bubbles from the fluid flow and returns them to the second inner space (40) to increase the probability that those bubbles will be dissolved into the fluid.
(FR)L'invention concerne un appareil (10) de dissolution d'un gaz dans un liquide pouvant contenir au moins un gaz dissous. L'appareil (10) comprend un premier tube (2) orienté verticalement définissant un premier espace intérieur (32) et un second tube (14) orienté verticalement d'un diamètre plus large que le premier tube (12) et orienté de manière concentrique autour du premier tube (12). L'espace entre le premier et le second tube correspond à un second espace intérieur (40). Le gaz est introduit par une entrée (18) dans le second espace intérieur (40). L'appareil (10) comprend un dispositif (20) d'accélération servant à accélérer le flux de liquide dans le second espace intérieur (40). L'appareil comprend un collecteur (22) de bulles hélicoïdal servant à enlever les bulles fugitives (non dissoutes) du flux liquide et à les renvoyer dans le second espace intérieur (40) afin d'augmenter la probabilité de dissolution des bulles dans le liquide.
