CARBONATION DEVICE FOR CEMENT-CONTAINING MATERIAL, AND CARBONATION METHOD FOR CEMENT-CONTAINING MATERIAL
To provide a carbonation device for a cement-containing material capable of increasing the quantity of a carbonated cement-containing material to be mixed into concrete, etc., more than the prior arts.SOLUTION: A carbonation device for a cement-containing material comprises: a first heat exchanger chamber; a raw material introduction port which introduces a granular cement-containing material into the first heat exchange chamber; a first introduction port which introduces a high-temperature first gas containing CO2 into the first heat exchange chamber; a first exhaust port which is disposed at a vertically higher position than the first introduction port and through which the gas in the first heat exchange chamber is exhausted; a second heat exchange chamber which is disposed while communicating with the first heat exchange chamber vertically lower than the first heat exchange chamber and through which the cement-containing material flows in from the first heat exchange chamber; a second introduction port through which a second gas at a lower temperature than the first gas is introduced into the second heat exchange chamber; a second exhaust port which is disposed at a vertically higher position than the second introduction port and through which the gas in the second heat exchange chamber is exhausted; and a raw material discharge port for discharging the cement-containing material passing the inside of the second heat exchange chamber in which the second gas is circulated.SELECTED DRAWING: Figure 1
【課題】炭酸化後のセメント含有物のコンクリート等への混合量を従来よりも高めることのできる、セメント含有物の炭酸化装置を提供する。【解決手段】セメント含有物の炭酸化装置は、第一熱交換室と、第一熱交換室内に粒状のセメント含有物を導入する原料導入口と、第一熱交換室内にＣＯ2を含有する高温の第一ガスを導入する第一導入口と、第一導入口よりも鉛直上方の位置に配置され第一熱交換室内のガスを排出する第一排出口と、第一熱交換室よりも鉛直下方において第一熱交換室と連絡して配置され第一熱交換室からセメント含有物が流入される第二熱交換室と、第二熱交換室内に第一ガスよりも低温の第二ガスを導入する第二導入口と、第二導入口よりも鉛直上方の位置に配置されて第二熱交換室内のガスを排出する第二排出口と、第二ガスが通流する第二熱交換室内を通過した後のセメント含有物を排出する原料排出口とを備える。【選択図】図１
