Description
図1は、本発明の第1の実施形態に係る気液接触装置を備えたCO2回収装置の概略図である。図1に示すように、このCO2回収装置10は、ボイラやガスタービンなどの産業設備から排出されたCO2を含有する排ガス11中のCO2を回収して高濃度のCO2ガス55として排出する装置である。このCO2回収装置10は、CO2を含有する排ガス11が導入される冷却塔13と、この冷却塔13の後段に設けられたCO2吸収塔15と、このCO2吸収塔15の後段に設けられた再生塔17とを具備する。
次に、本発明の第2の実施の形態について説明する。なお、以下においては、上述した第1の実施の形態に係る気液接触装置100と共通する構成要素には同一の符号を付し、説明の重複を避ける。
図5は、本発明の第3の実施の形態に係る気液接触装置100における単位ユニット301の模式的な斜視図である。なお、図5においては、説明の便宜上、第1充填材層311、第2充填材層312及び第3充填材層313を離間して示している。図5に示すように、本実施の形態においては、液分散器120の下方に充填材部310が配置される。この充填材部310は、第1充填材層311、第2充填材層312及び第3充填材層313が積層されて構成される。充填材部310の第1充填材層311、第2充填材層312及び第3充填材層313は、それぞれ概して略直方体形状の板状部材として構成されている。第1充填材層311、第2充填材層312及び第3充填材層313は、それぞれ複数の波板状の板状部材が斜めに積層して構成され、各板状部材の間にCO2吸収液14の流路311a、312a、313aが設けられている。すなわち、本実施の形態においては、CO2吸収液14の流路311a、312a、313aが排ガス11の流路311a、312a、313aの延在方向D2,D3に対して波状に設けられている。その他の構成については、上述した第1の実施の形態に係る気液接触装置100と同一の構成を有するので説明を省略する。
図6は、本発明の第4の実施の形態に係る気液接触装置400の模式的な斜視図である。図6に示すように、本実施の形態に係る気液接触装置400は、内部に排ガス11が通過する充填材部110と、この充填材部110上にそれぞれ設けられた液分散器120とを有する単位ユニット101が複数並設(本実施の形態では8つ)して配置されている。各単位ユニット101の間には、各単位ユニット101を仕切る仕切部材401が設けられている。その他の構成については、上述した第1の実施の形態に係る気液接触装置100と同一の構成を有するので説明を省略する。
次に、本発明の効果を明確にするために行った実施例について説明する。本発明者らは、上述した第1の実施の形態に係る気液接触装置100(実施例1)及び第4の実施の形態に係る気液接触装置400(実施例2)について、従来の気液接触装置(比較例)を基準としてCO2吸収率比を評価した。その結果を図7に示す。図7に示すように、充填材部110及び液分散器120を備えた単位ユニット101を複数設けた上記第1の実施の形態に係る気液接触装置100は、従来の気液接触装置に対して約1.04倍のCO2吸収率比を示した。この結果は、液分散器120での液偏流、複数の充填材部110内における気液偏流及び隣接する充填材部110への気液偏流の拡大を防ぐことができたためと考えられる。また、複数の単位ユニット101間に仕切部材401を配置した上記第4の実施の形態に係る気液接触装置400は、従来の気液接触装置に対して約1.05倍のCO2吸収率比を示した。この結果は、仕切部材401によって複数の充填材部110が区分されるので、隣接する充填材部110への気液偏流の拡大をより一層防ぐことができたためと考えられる。
