Abstract

A pump housing of the carbon dioxide-containing gas recovery apparatus is formed with a first chamber and a second chamber partitioned by a partition wall. The first and second chambers and communicate with each other through a third chamber. The first chamber 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 in the water. When a pair of six-blade rotors oppositely disposed on two axes and in the third chamber compress the bubbles to be refined into different bubbles, 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.

Claims2

Dependent claims

A carbon dioxide-containing gas recovery apparatus which dissolves a carbon dioxide-containing gas in water thereby to recover the carbon dioxide-containing gas, the apparatus comprising:

a pump housing having a first chamber provided with a water supply opening at a side of the first chamber and a carbon dioxide-containing gas inlet, a second chamber provided with a water outlet, and a third chamber communicating between the first and second chambers;
and
a rotary mixing section including a pair of multiblade rotors and an electric motor driving the rotors, the electric motor being installed at an upper side of the pump housing,
wherein water is supplied through the water supply opening into the first chamber and a carbon dioxide-containing gas is supplied through the inlet into the first chamber to be dissolved in the water;
and
wherein the water in which the carbon dioxide-containing gas is dissolved is pressure-fed from the first chamber to the third chamber by the rotary mixing section to be discharged through the water outlet.
