Carbon-dioxide-containing gas recovery device

The invention provides a carbon-dioxide-containing gas recovery device that is inexpensive and in which the efficiency of recovering carbon-dioxide-containing gas is improved. A pump housing 11 of a carbon-dioxide-containing gas recovery device 10 has formed therein a first chamber 23 and a second chamber 26 divided by a partition wall 20a. The first chamber and the second chamber communicate through a third chamber 20. The first chamber communicates with a water supply port and a gas inlet for a carbon-dioxide-containing gas. When the carbon-dioxide-containing gas is blown into water fillingthe first chamber, the carbon-dioxide-containing gas dissolves into the water, and the carbon-dioxide- containing gas that did not dissolve in the water is present as bubbles A in the water. When a pair of six-leaf rotors 40, 40 disposed in the third chamber 20 on two shafts 41a, 41b so as to face each other compress the bubbles A and atomize the bubbles A into bubbles B, the carbon-dioxide-containing gas can be made to f
