<P>PROBLEM TO BE SOLVED: To provide a small-sized carbon dioxide gas recovery device which can easily recover a carbon dioxide gas discharged from a steel plant or the like at low cost. <P>SOLUTION: The carbon dioxide gas recovery device is equipped with a roots pump 3 which can freely rotate a pair of roots rotors 26 accommodated in a pump casing 4 by a drive motor 38, has a collision member 50 which makes an air introduction port 46 collide with sucked water at a pipe conduit communicating with a suction pipe 45, sucks water from the suction pipe 45 by the operation of the roots pump 3 and generates a large volume of bubbles by making water mixed with air taken in from the air introduction port 46 collide with the collision member 50, makes fine the bubbles by compression action by the roots pump 3, and dissolves the carbon dioxide gas by discharging the water containing the fined bubbles from a discharging pipe 55 into the water of a purification tank, a river or the like. <P>COPYRIGHT: (C)2012,JPO&INPIT |
