<p>PURPOSE:To provide an apparatus in which a large vibration of the froth layer in a liquid tank caused by gas ejection from gas exhaust gas exhaust into liquid is prevented in advance in a miltitubular gas-liquid contact apparatus in which a lot of gas introduction pipes having the exhaust nozzle on the lower side wall are installed in liquid. CONSTITUTION:In a gas-liquid contact apparatus in which a lot of gas introduction pipes 1 having a gas exhaust nozzle 2 on the lower side wall are installed in a large liquid tank so that the exhaust nozzles 2 are located below the stationary level in the liquid tank, more than one partition member 3 is installed in the liquid tank in such a way that its lower end is positioned at the same level with the exhaust nozzle 2 of the gas introduction pipe 1, or close to or below the nozzle 2, while its upper end is located close to the surface of the froth layer, and the partition member 3 is supported by a plurality of gas introduction pipes 1, so that a plurality of bubble passage areas (a) surrounded by the partition members 3 are formed in the liquid tank.</p> |
