<p>PROBLEM TO BE SOLVED: To prevent the blow-through of CO2-containing exhaust gas in a packed bed when CO2 in the CO2-containing exhaust gas is absorbed and fixed by solid particles containing non-carbonated Ca by introducing the CO2-containing exhaust gas into a reaction tank packed with an aggregate of solid particles containing non- carbonated Ca in a moisture-containing state. SOLUTION: In a reaction apparatus for discharged carbon dioxide absorbing reaction, having the reaction tank packed with the aggregate of the solid particles containing non-carbonated Ca, the reaction tank has at least one constitution selected from constitution (a) such that a vibrator is provided in the reaction tank to apply vibration to the side wall thereof, constitution (b) such that inclination reducing the horizontal cross-sectional area in the reaction tank downwardly is applied to the inner wall surface of the reaction tank, constitution (c) such that the horizontal cross section of the reaction tank is formed into a circular or oval shape or the inner corner part of the reaction tank is formed into an arcuate or oval arcuate shape and constitution (d) such that an exhaust gas introducing part is provided in the upper part of the reaction tank and an exhaust gas discharge part is provided in the bottom part thereof.</p> |
