GAS-LIQUID CONTACT DEVICE AND CO2 RECOVERY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a gas-liquid contact device that can not only bring gas and liquid supplied into a tower to be efficiently in contact with each other by almost equally diffusing the liquid to the inside of the tower and by reducing the amount of the liquid which is in contact with a wall surface of the tower but also reduce the cost and to provide a CO2recovery device.

SOLUTION: The gas-liquid contact device related to this embodiment includes a plurality of spray nozzles 22A which is disposed in a CO2absorption tower, allows the CO2absorption liquid to spray downward in the CO2absorption tower through which exhaust gas moves upward to be passed; and allows the upwardly moving exhaust gas and CO2absorption liquid to be in contact with each other. The spray nozzle 22A includes: a liquid diffusion nozzle 25 disposed nearer to the inside than to a dedicated wall surface nozzle 26 in the CO2absorption tower; and the dedicated wall surface nozzle 26 disposed along a wall surface 27 of the CO2absorption tower.
