CARBON DIOXIDE-CONTAINING GAS RECOVERY APPARATUS

[Overcoming Means] A pump housing 11 of the carbon dioxide-containing gas recovery apparatus 10 is formed with a first chamber 23 and a second chamber 26 partitioned by a partition wall 20a. The first and second chambers 23 and 26 communicate with each other through a third chamber 20. The first chamber 23 communicates with a water supply opening and a carbon dioxide-containing gas inlet. When blown against water filling the first chamber, a carbon dioxide-containing gas is dissolved in the water, and the carbon dioxide-containing gas remaining undissolved exists as bubbles A in the water. When a pair of six-blade rotors 40 oppositely disposed on two axes 41a and 41b in the third chamber 20 compress the bubbles A to be refined into bubbles B, the carbon dioxide-containing gas can further be dissolved in the water by a compression action. An aqueous solution of carbon dioxide-containing gas is discharged from a water outlet communicating with the second chamber.
