Concerning gas masks for protecting the human body from CO).
（従来の技術）
炭鉱、鉱山などの坑内に於ては、火災、爆発に
よつて高濃度のCOが充満する場合が多く、その
雰囲気から人間の生命を守るために、従来は例え
ば酸化マンガン、酸化銅を主体とする金属酸化物
系の触媒であるホプカライト（主成分MnO2−
CuO）が知られている。(Prior art) The mines of coal mines, mines, etc. are often filled with high concentrations of CO due to fires and explosions. Conventionally, in order to protect human life from this atmosphere, for example, manganese oxide, Hopcalite (main component MnO 2 −
CuO) is known.
しかしこのホプカライト触媒は室温に於てCO
からCO2へ酸化するが水分によつて酸化能力が低
下することから貴金属触媒等を単独もしくはホプ
カライトと併用して用いることも考えられCOの
酸化自体はほヾ満足するに至つている。 However, this hopcalite catalyst does not react with CO at room temperature.
However , since the oxidation ability is reduced by moisture, the use of precious metal catalysts alone or in combination with hopcalite has been considered, and the oxidation of CO itself has become more or less satisfactory.
（解決すべき問題点）
ところがその反応形態を考えると、
CO＋１／２O2→CO2＋Ｑ（Ｑ≒94.1Kcal／mol）
で、その反応の際に100℃前後の高熱を発生し、
これにより高熱となつた空気を人間が吸うことに
より火傷を負つたり、余りの高熱に耐えられなく
なつて、防毒マスクを取り外し、結局CO中毒に
なる等の事故が発生している。(Problems to be solved) However, when considering the reaction form, CO + 1/2O 2 → CO 2 + Q (Q≒94.1Kcal/mol), high heat of around 100℃ is generated during the reaction.
This has resulted in accidents such as people suffering burns from breathing in the highly heated air, or people becoming unable to withstand the excessive heat and removing their gas masks, resulting in CO poisoning.
（問題点を解決するための手段）
本発明はこのような難点を解決すべく種々検討
の結果なされたもので、酸化触媒によつて生じる
熱量を、CO2と吸熱反応する物質によつて除熱す
るものである。(Means for Solving the Problems) The present invention was developed as a result of various studies to solve these difficulties, and it eliminates the amount of heat generated by the oxidation catalyst using a substance that undergoes an endothermic reaction with CO 2 . It is something that heats up.
（作用）
上記の酸化と吸熱の２つの作用によつてCOは
CO2となりかつ吸気は低温化されるものである。(Action) Due to the two actions of oxidation and endotherm mentioned above, CO
It becomes CO 2 and the temperature of the intake air is lowered.
（実施例） 以下本発明の実施例について説明する。(Example) Examples of the present invention will be described below.

５は低温化された空気で６は防毒マスク１の頭部
装着用ひもである。 The figure is a cross-sectional view of the main parts of a gas mask. 1 is a gas mask, 2 is an oxidation catalyst, 3 is a substance that has an endothermic reaction with CO 2 , and 4 is air containing CO that flows in the direction of the arrow.
5 is cooled air, and 6 is a string for attaching the gas mask 1 to the head.

の口、鼻に供給するようになる。 If you put such a gas mask on your face and tighten the head strap properly, the mask will be fixed to cover your face, and the air 4 containing CO will be released into the oxidation catalyst 2.
It is oxidized to become CO 2 , and when it reacts with this CO 2 , it absorbs heat by the substance 3 that undergoes an endothermic reaction and becomes cooled air 5, which is then supplied to the human mouth and nose. .

に担持させて使用する。 Here, the oxidation catalyst is MnO 2 :CuO = 60:40 (ωt%)
hopcalite, a platinum catalyst, a palladium catalyst, etc. may be used. Such an oxidation catalyst is generally supported on powdered or fluid activated carbon, γ-alumina powder, or the like.
次にCO2と吸熱反応する物質は例えば酸化マグ
ネシウム（MgO）、酸化カルシウム（CaO）があ
り、その反応式は次のとおりである。 Next, substances that undergo an endothermic reaction with CO 2 include, for example, magnesium oxide (MgO) and calcium oxide (CaO), and the reaction formula is as follows.
MgO＋CO2→MgCO3 −2671KJ／CO2−mol
CaO＋CO2→CaCO3 −4066KJ／CO2−mol
これらの反応は常温から100℃近くで円滑に行
なわれ、吸熱反応であり、CO2生成に際し発生し
た高熱をここで消費し吸気を低温とし無害化する
ことができる。MgO＋CO 2 →MgCO 3 −2671KJ/CO 2 −mol CaO＋CO 2 →CaCO 3 −4066KJ/CO 2 −mol These reactions occur smoothly from room temperature to around 100°C and are endothermic reactions, meaning that the The high heat is consumed here, making the intake air cold and harmless.
（発明の効果）

COを無害なCO2とするとともに、このCO2を引
きつづいて吸熱反応する物質により、炭酸塩に変
換するので、吸気中にはCOがなく低温でしかも
酸素含有量の大きい空気を吸うことができるの
で、その間に危地を脱出する余裕を得ることがで
きる。(Effect of the invention) As described above, the present invention uses an oxidation catalyst to
In addition to converting CO into harmless CO 2 , this CO 2 is subsequently converted into carbonate by a substance that undergoes an endothermic reaction, so there is no CO in the inhaled air, making it possible to breathe in low-temperature air with a high oxygen content. This gives you time to escape from the dangerous situation.
