〔産業上の利用分野〕
本発明は、気体中の二酸化炭素から酸素を得る方法に係
り、特に空気中の二酸化炭素を分離回収し、生化学的に
酸素を得る方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method of obtaining oxygen from carbon dioxide in a gas, and particularly a method of separating and recovering carbon dioxide in the air and biochemically obtaining oxygen. Regarding.
本発明の方法は、密閉空間例えば地下空間、海洋開発に
おける空間、宇宙産業における空間及び潜水艦内等にお
ける空気中の二酸化炭素の除去、回収及び酸素の製造に
、家庭、病院における空気の浄化に、また、各種産業に
おける酸素の製造用に利用できる。The method of the present invention is useful for removing and recovering carbon dioxide from the air and producing oxygen in closed spaces such as underground spaces, spaces in ocean development, spaces in the space industry, and inside submarines, and for air purification in homes and hospitals. It can also be used for producing oxygen in various industries.
まず、密閉空間における空気中二酸化炭素の除去・回収
および酸素の製造について述べる。First, we will discuss the removal and recovery of atmospheric carbon dioxide and the production of oxygen in a closed space.
密閉空間としての地下空間の利用は、今後土地の有効利
用の観点で一層重要となると予想され、現在その開発が
進行している。The use of underground space as a closed space is expected to become even more important in the future from the perspective of effective land use, and its development is currently underway.
一方、地下空間では、人の活動により発生する二酸化炭
素(以下C02)の浄化(空気浄化)をいかに有効に行
うかが課題になっている。On the other hand, in underground spaces, the challenge is how to effectively purify carbon dioxide (hereinafter referred to as C02) (hereinafter referred to as C02) generated by human activities (air purification).
空気浄化の現状技術は、通常空気中のC02濃度をモニ
ターし、該濃度が一定濃度以上に達しない様に地上の大
気中に高濃度CD,を含む空気?放出し、代わりに地上
から清浄空気の導入が行われている。Current air purification technology usually monitors the CO2 concentration in the air, and prevents the concentration from reaching a certain level by cleaning air that contains high concentrations of CD in the air above the ground. Instead, clean air is introduced from the ground.
この方法は、地上大気に高濃度CD2を放出するので、
地上大気中のCO2a度を高めることや、導入空気が清
浄でない場合(例えば、都心部では特に夏期においては
“いわゆる大気汚染”のために導入空気が汚染されてい
る)、該空気の清浄化を行う必要があり課題であった。This method releases high concentrations of CD2 into the surface atmosphere, so
Increasing the level of CO2a in the ground atmosphere, and in cases where the introduced air is not clean (for example, in urban areas, especially in the summer, the introduced air is polluted due to "so-called air pollution"), the air should be purified. This was an issue that needed to be done.
特に、近年放出CD■による地球規模の環境問題が深刻
化しており人間活動に伴い放出されるCO,は、地球の
温暖化現象の主因と言われており、新規な環境破壊物質
として注目されており、大気へのCD2放出に対し見直
しが行われている。In particular, in recent years, global environmental problems due to emitted CD■ have become increasingly serious, and CO, released due to human activities, is said to be the main cause of global warming and is attracting attention as a new environmentally destructive substance. As a result, CD2 emissions into the atmosphere are being reviewed.
又、海洋開発や潜水艦等の密閉空間において人の活動に
より発生したCOiは、薬剤を用い吸収除去を行い、人
の生命維持に必要な酸素(以下0,)は海水の電気分解
により得ている。ここでは、廃棄物が副生(二次公害)
することやエネルギコストが高いことからCO■の処理
や02の入手法が課題であった。In addition, COi generated by human activities in ocean development and closed spaces such as submarines is absorbed and removed using chemicals, and the oxygen (hereinafter referred to as 0) required to sustain human life is obtained by electrolysis of seawater. . Here, waste is a byproduct (secondary pollution)
Because of the high energy cost and the high cost of CO2, the treatment of CO2 and the method of obtaining 02 have been issues.
このように、放出CD,は、最近特に地球規模の環境問
題に対する汚染物質として注目されてきているが、従来
の処理方法は種々の課題があり、満足すべき放出CO2
の利用法はなかった。As described above, emitted CO2 has recently been attracting attention as a pollutant, especially for global environmental problems, but conventional treatment methods have various problems, and it is difficult to achieve a satisfactory level of emitted CO2.
There was no way to use it.
そこで、本発明は、気体中に放出されるCD2を有効に
回収して、それから、経済的に酸素を取得する方法を提
供することを目的とする。Therefore, an object of the present invention is to provide a method for effectively recovering CD2 released into a gas and economically obtaining oxygen from it.
上記目的を達戒するために、本発明では、気体中の二酸

酸素を得ることを特徴とする気体中の二酸化炭素から酸
素を得る方法としたものである。In order to achieve the above object, the present invention separates and recovers carbon dioxide in gas by one or more methods selected from membrane separation method, pressure fluctuation type adsorption separation method, or separation method using ion exchanger. This is a method for obtaining oxygen from carbon dioxide in a gas, which is characterized by supplying the recovered carbon dioxide to a reactor made of plants growing in a culture solution and obtaining oxygen through photosynthesis or reaction.
次に、本発明を詳しく説明する。Next, the present invention will be explained in detail.
第1図は、地下空間における空気中のCO2を除去、回
収し、酸素を製造するための工程図の一例である。FIG. 1 is an example of a process diagram for removing and recovering CO2 from the air in an underground space and producing oxygen.
ここでは、CD2の分離・回収は膜分離法、C02から
02への変換は微細藻類を用いた場合である。Here, the separation and recovery of CD2 is performed using a membrane separation method, and the conversion of CO2 to 02 is performed using microalgae.
