Title (EN) A COOLING TOWER FOR COOLING A LIQUID WITH A GAS
(FR) TOUR DE REFROIDISSEMENT POUR REFROIDIR UN LIQUIDE AU MOYEN D'UN GAZ
Abstract:
(EN) A cooling tower (2) for cooling a liquid (4) with a gas (6), which cooling tower (2) comprises: (i) a vessel (8) for receiving the gas (6) passing upwardly and the liquid (4) passing downwardly, with the liquid (4) being hotter than the gas (6); (ii) a gas outlet (14) which is at a top portion (16) of the vessel (8) and which is for allowing the gas (6) to pass out of the vessel (8); (iii) a support member (20) which is positioned across a bottom portion (22) of the vessel (8); (iv) a plurality of apertures (24) which are in the support member (20) and through which the gas (6) and the liquid (4) are able to pass; (v) a fluidised bed (26) of packing elements (28) on the support member (20); (vi) liquid emitting means (30) which is positioned in the vessel (8) above the fluidised bed (26), and which is for emitting the liquid (4) to be cooled such the liquid (4) passes downwardly towards the fluidised bed (26); (vii) pump means (32) for pumping the liquid to the liquid emitting means (30); and (viii) a fan (34) for blowing the gas upwardly through the fluidised bed (26), and the cooling tower (2) being such that it includes: (ix) control means (31) for controlling (a) the velocity of the gas through the vessel (8), and (b) the liquid to gas ratio in the vessel (8), whereby the fluidised bed (26) is caused to operate at a tumbling rate which when combined with the selected pre- fluidised packing height causes an approach temperature of below 10°F (5.6°C); (x) wherein the tumbling rate is controlled by a combination of controlled gas velocity and liquid to gas ratio creating turbulent mixing and tumbling of packing elements (28) in the fluidised bed (26); (xi) and wherein the pre-fluidised height of the fluidised bed (26) is from 0.15 - 1.0m.
(FR) L'invention concerne une tour de refroidissement (2) pour refroidir un liquide (4) au moyen d'un gaz (6), laquelle tour de refroidissement (2) comprend : (i) une cuve (8) pour recevoir le gaz (6) passant vers le haut et le liquide (4) passant vers le bas, le liquide (4) étant plus chaud que le gaz (6) ; (ii) une sortie de gaz (14) qui se trouve au niveau d'une partie supérieure (16) de la cuve (8) et qui sert à permettre au gaz (6) de sortir de la cuve (8) ; (iii) un élément de support (20) qui est positionné à travers une partie inférieure (22) de la cuve (8) ; (iv) une pluralité d'ouvertures (24) qui se trouvent dans l'élément de support (20), et à travers lesquelles le gaz (6) et le liquide (4) peuvent passer ; (v) un lit fluidisé (26) d'éléments de conditionnement (28) sur l'élément de support (20) ; (vi) un moyen d'émission de liquide (30) qui est positionné dans la cuve (8) au-dessus du lit fluidisé (26), et qui sert à émettre le liquide (4) à refroidir de telle sorte que le liquide (4) passe vers le bas vers le lit fluidisé (26) ; (vii) un moyen de pompe (32) pour pomper le liquide vers le moyen d'émission de liquide (30) ; et (viii) un ventilateur (34) pour souffler le gaz vers le haut à travers le lit fluidisé (26), et la tour de refroidissement (2) étant telle qu'elle comprend : (ix) un moyen de commande (31) pour commander (a) la vitesse du gaz à travers la cuve (8), et (b) le rapport liquide/gaz dans la cuve (8), le lit fluidisé (26) étant amené à fonctionner à une vitesse de rotation qui, lorsqu'elle est combinée à la hauteur de conditionnement pré-fluidisée sélectionnée, entraîne une température d'approche inférieure à 10 °F (5,6 °C) ; (x) la vitesse de rotation étant commandée par une combinaison de la vitesse de gaz commandée et du rapport liquide/gaz créant un mélange turbulent et une rotation d'éléments de conditionnement (28) dans le lit fluidisé (26) ; (xi) et la hauteur pré-fluidisée du lit fluidisé (26) étant comprise entre 0,15 et 1,0 m.
