It is well known that breathing air with high levels of oxygen can be used for recovery, and the present invention relates to an oxygen cylinder containing oxygen used for this purpose.

Since it is filled with 150 Kg/cm 2 G of compressed gas, it is guaranteed by the calculated wall thickness that it will not break under pressure and is therefore extremely heavy. For example, 50 for 6 containers

For example, there have been reports of fires caused by toxic gases, which can be avoided by escaping while breathing oxygen or air even for a short time, but the cylinders mentioned above are too heavy, and chemically reactive oxygen products are does not operate in an emergency due to handling reasons.

も大量生産されており割安である。Means for Solving the Problem When compressing and filling oxygen gas, etc., the filling capacity is determined by this pressure. For example, 150Kg/cm 2 G
The gas released from a container filled with pressure is
It is 150. Compressed gas of 10 kg/cm 2 G or more is subject to the High Pressure Gas Control Law, so the specifications, pressure testing, storage, etc. of the container are complicated, and the gas becomes heavy and expensive. If we use pressure-resistant aerosol cans, which are not covered by this law and are currently mass-produced, we can expect a significant cost reduction.Currently in Japan, the canister size is 500ml (in the United States, it is 1000ml, and it is expected to expand in Japan as well). The maximum amount of gas is 10 kg/cm 2 G, and the amount of gas that can be released is 5, which is small in quantity. Incidentally, commercially available aerosol cans are guaranteed to have a pressure resistance of 13 kg/cm 2 G, and the release valve mechanism that seals the cans, the Mauten Cup, is also mass-produced and inexpensive.

As the standard for firefighting disaster prevention equipment is approximately 4 minutes per minute, it is desirable to have a storage capacity of approximately 10 minutes or more. When used for the purpose of refreshing the mood, such as simply inhaling fresh air, for example, aromatherapy containing fragrances, the amount may not necessarily be limited to 10 kg/cm 2 when using the above aerosol can. The following gas filling is insufficient.

充する方法を採用した。 In the present invention, we have invented a means to store as much oxygen as possible within the legal regulations using the above-mentioned general distribution can. That is, the present invention focuses on the fact that activated carbon stores oxygen, and adopts a method of storing activated carbon in the aerosol can and pressurizing it with oxygen gas or oxygen-enriched air.

に充填した場合実線は活性炭なしの場合を示す。 For example, granular activated carbon is stored in an AE420 can (inner volume: 420 ml), and oxygen is pressurized at 20°C up to 10 kg/cm 2 G. When this was released by opening the valve, 10.5% of oxygen was obtained. In other words, 2.5 times more oxygen was stored per space volume. The volume of compressed gas is supposed to be determined by Boyle-Schard's law, but this relationship no longer holds if activated carbon is present. Figure 1 shows O 2 :N 2 in a 480ml volume can.
The amount of gas that can be released when pressurizing gas at =65:35 (V%) shows the relationship with the internal pressure of the tank.The dotted line is dry activated carbon, and the chain line is when wet activated carbon is filled to 90% volume. The solid line shows the case without activated carbon.

においても安全であつた。 For example, it is known that when gas is pressurized into a container filled with activated carbon, the amount of compressed gas stored increases.
day). According to this report, it is possible to use methane, natural gas (propane, propylene, isobutane, isoztyrene, etc.), ethylene, nitrogen, and hydrogen. The reason why there is no mention of oxygen is presumed to be because in the past, compressed oxygen gas mixed with organic matter, carbon, etc. was considered extremely dangerous and taboo. In fact, in the inventor's experiments, when activated carbon was present, it exploded at 57 kg/cm 2 when it was sequentially pressurized and filled at 40°C. However, at the upper limit of the range of the present invention, that is, 10Kg/ cm2, the temperature is 100℃.
It was also safe.
次に問題になると考える点は、圧力下において
酸素が活性炭と反応しCOまたはCO2を生成する
ことである。これらのガスは人間の呼吸に望まし
くない生理作用があるので、注意すべきことであ
る。実験的に求めると、図面第２図に示す様に、
圧力が10Kg／cm2を超えると急速に活性炭の酸化に
よるCO＋CO2ガスが増えることが判る。従つて
10Kg／cm2Ｇ以下の圧入とする条件が重要である。 The next point that we think is problematic is that under pressure oxygen reacts with activated carbon to produce CO or CO 2 . Caution should be taken as these gases have undesirable physiological effects on human respiration. When experimentally determined, as shown in Figure 2 of the drawing,
It can be seen that when the pressure exceeds 10Kg/cm 2 , the amount of CO + CO 2 gas increases rapidly due to the oxidation of activated carbon. accordingly
It is important to maintain a press fit of 10 kg/cm 2 G or less.
高圧ガス取締法によれば、容器が30ml以下の場
合圧力は限定されてないし、また逆に10Kg／cm2以
下であれば容器の大きさは制限されることはな
い。本発明は、法的規定による経済性の制約を避
けるために請求の範囲の設定を行つたと同時に、
偶然上述の活性炭の酸化性を避ける条件でもあ
る。活性炭の有効表面積が高い程充填酸素量が多
いが、酸化ガスも多くなるのでその兼合が重要
で、チヤコール、木炭も代用し得る資源である。 According to the High Pressure Gas Control Law, there are no restrictions on the pressure if the container is 30ml or less, and conversely, there are no restrictions on the size of the container if it is 10Kg/cm 2 or less. The scope of the present invention has been defined in order to avoid economical constraints due to legal provisions, and at the same time,
This also happens to be a condition that avoids the oxidizing properties of activated carbon mentioned above. The higher the effective surface area of activated carbon, the greater the amount of oxygen it can fill, but since the amount of oxidizing gas also increases, it is important to balance these two aspects, and charcoal and charcoal are also resources that can be substituted.
次に問題になると考えられる第三の検討事項
は、富化空気においてN2が混在したとき活性炭
に対する吸蔵はO2の方が活性なため、初期放出
ガスはN2リツチになるのではないかと考えられ
るが、N2：O2＝50：50V％のガスを圧入し、初
期噴出のガスを分析したときO2＝48.0V％で実用
上問題にならないことが判つた。 The third consideration that is considered to be a problem is that when N 2 is mixed in enriched air, O 2 is more active in occluding O 2 in activated carbon, so the initial released gas may be rich in N 2 . However, when gas was injected at a ratio of N 2 :O 2 =50:50V% and the initial ejected gas was analyzed, it was found that O2 = 48.0V%, which was not a practical problem.
従つて本発明において適用する酸素富化空気と
は、空気の21V％以上のO2濃度のガスである。 Therefore, the oxygen-enriched air applied in the present invention is a gas with an O 2 concentration of 21 V% or more of air.
