ことにあり、そうすることによつて下記の如き多
くの優れた作用および効果が発現される。 As described above, the present invention is characterized by using an oxygen enricher that uses an adsorbent as a means to increase the oxygen concentration in the indoor atmosphere, and by mixing the oxygen-enriched air with air and blowing it indoors at a constant wind speed. By doing so, many excellent functions and effects such as those described below will be realized.

給する方法では危険であり、しかも安定供給性
に欠け、高価でありしかも供給場所に制限があ
る。(a) The oxygen-enriched air taken into the room is produced using an oxygen enricher that uses an adsorbent, so cheap atmospheric air is the raw material and can be stably supplied at all times. On the other hand, the method of supplying oxygen from a high-pressure oxygen cylinder is dangerous, lacks a stable supply, is expensive, and has limitations on supply locations.
(b) 吸着剤を使用する酸素富化器を用いるので大
気空気中の汚染ガス例えば窒素酸化物、硫黄酸

すことができる。(c) The living environment, especially the indoor atmosphere, has a high oxygen concentration at most.
30% is sufficient, and to achieve this, the oxygen concentration needs to be slightly higher than that of normal atmospheric air, so the oxygen enricher described above, which uses atmospheric air as a raw material, is optimal, and a small device can sufficiently perform its function. be able to.

常時良好な酸素状態に保持することができる。(e) the oxygenated air introduced into the room from said oxygen enricher is mixed with a further air flow of at least 0.1 m/s, preferably from 0.2 to 10 m/s;
More preferably, since the air is blown into the room at a wind speed of 0.2 to 4 m/sec, the atmosphere in the room can be uniformly maintained at the desired oxygen concentration throughout the room, making the entire room a safe and sanitary environment. It becomes possible to maintain. Therefore, in addition to easily maintaining the indoor atmosphere at a high oxygen concentration of 21 to 30% (by volume), it is also possible to prevent oxygen deficiency in rooms where a fire or heater is used or where many people are present. Not only can this condition be prevented, but the atmosphere can also be maintained in a good oxygen condition at all times.
以上説明した本発明方法により、室内の雰囲気
における酸素濃度は30％（容量）以下に維持する
ことが好ましく、特に21〜30％（容量）の範囲が
好ましい。 According to the method of the present invention described above, the oxygen concentration in the indoor atmosphere is preferably maintained at 30% (by volume) or less, particularly preferably in the range of 21 to 30% (by volume).
30％（容量）以上の高酸素濃度雰囲気は、呼吸

範囲である。 An atmosphere with a high oxygen concentration of 30% (by volume) or more may be effective and necessary for the treatment of patients with diseases such as those of the respiratory tract or the heart tract, but if a healthy person spends a long time in that atmosphere, Since human body tissues are adapted to an atmosphere with an oxygen concentration of approximately 21% (by volume), this applicability may not be achieved smoothly when the atmosphere changes from a high oxygen concentration to a normal atmosphere. This is not desirable. On the other hand, as the oxygen concentration increases, common members become more flammable, and an atmosphere with an excessively high oxygen concentration poses a problem in terms of fire prevention. A particularly preferable oxygen concentration is in the range of 22% to 25% (by volume), which is effective and poses no particular problem in terms of human health and fire prevention measures.
本発明の酸素富化器に用いられる酸素と窒素と
の選択吸着剤としては大きく分けて２種類ありそ
の一つは酸素より窒素の方が吸着しやすい吸着剤
であり例えばゼオライトである。ゼオライトには
天然と合成の２種類があるが、いづれの種類も使
用できる。 There are roughly two types of selective adsorbents for oxygen and nitrogen used in the oxygen enricher of the present invention, one of which is an adsorbent that more easily adsorbs nitrogen than oxygen, such as zeolite. There are two types of zeolite: natural and synthetic, and either type can be used.
他の一つは酸素の方が窒素より吸着しやすい吸
着剤であり、例えば活性炭等のような炭素粒子等
である。 The other is an adsorbent that adsorbs oxygen more easily than nitrogen, such as carbon particles such as activated carbon.
酸素濃縮の操作としては、一般には大気空気を
加圧して吸着剤の充填しているタンク類へ入れ
る。窒素の方が酸素より吸着されやすい では、
大気中の窒素がはやく吸着され、残つた気体が酸
素に富んだ気体となり、これが酸素濃縮空気とし
て利用できる。 Oxygen concentration is generally performed by pressurizing atmospheric air and introducing it into tanks filled with adsorbent. Since nitrogen is more easily adsorbed than oxygen,
Nitrogen in the atmosphere is quickly adsorbed, and the remaining gas becomes oxygen-rich gas, which can be used as oxygen-enriched air.
吸着剤の再生は、一般には常圧に戻したりある
いは減圧にして吸着気体を脱着する。 The adsorbent is generally regenerated by returning it to normal pressure or reducing the pressure to desorb the adsorbed gas.
一方酸素の方が吸着されやすい では、吸着剤
により多くの酸素が吸着されており、吸着剤を減
圧などで再生するとき脱着気体が酸素濃縮気体と
なる。 On the other hand, in the case where oxygen is more easily adsorbed, a large amount of oxygen is adsorbed by the adsorbent, and when the adsorbent is regenerated under reduced pressure, the desorbed gas becomes an oxygen-enriched gas.
いずれにしても、この吸着−脱着をくりかえす
ことにより酸素濃縮空気が製造されるが、操作方
法として、圧力変動をくりかえす圧力スウイング
方式が、装置としてポンプだけであり、簡便であ
り、好ましく採用されている。場合によつては脱
着をはやめるために脱着時加熱することもある。 In any case, oxygen-enriched air is produced by repeating this adsorption-desorption process, but the pressure swing method, which repeats pressure fluctuations, is the preferred method of operation because it is simple and requires only a pump. There is. In some cases, heating may be applied during desorption to speed up desorption.
連続的に酸素濃縮空気を得ようとする場合、貯
蔵タンク等を設け、そこに一旦貯めて除々にとり
だすこともできるが多くは少くとも２つの吸着剤
充填タンク類を用い吸着工程と脱着工程をずらし
て、連続的にとりだせるように操作している。も
ちろんこの場合も貯蔵タンク等を設け流量の安定
化をはかることも行うことができる。 When trying to obtain oxygen-enriched air continuously, it is possible to set up a storage tank, etc., store it there and then take it out gradually, but in most cases at least two adsorbent-filled tanks are used to carry out the adsorption process and desorption process. It is operated so that it can be taken out continuously by shifting it. Of course, in this case as well, a storage tank or the like may be provided to stabilize the flow rate.
吸着剤の種類としては、ゼオライト等の吸着剤
を用いた場合、大気中のSOx、NOx、CO2、水
蒸気などの気体も酸素に比べてはやく吸着され、
酸素濃縮空気中よりとり除かれる。特にSOx、
NOxなどは人体にとつて有害であり、それゆえ
ゼオライト等は好ましい吸着剤である。 As for the type of adsorbent, when using an adsorbent such as zeolite, gases such as SOx, NOx, CO 2 and water vapor in the atmosphere are adsorbed more quickly than oxygen.
Removed from oxygen-enriched air. Especially SOx,
NOx and the like are harmful to the human body, so zeolites and the like are preferred adsorbents.
酸素濃縮空気中の酸素濃圧は、使用される吸着
剤の種類操作条件によつて異なるが、この吸着剤
を用いる酸素濃縮法は、はばひろく酸素濃度をか
えることができるのが特徴であり、一般には酸素
濃度は30〜99％の範囲である。 The oxygen concentration pressure in oxygen-enriched air varies depending on the type of adsorbent used and the operating conditions, but the oxygen concentration method using this adsorbent is characterized by the ability to vary the oxygen concentration over a wide range of conditions. , generally the oxygen concentration ranges from 30 to 99%.
かくして選択吸着剤を用いた酸素濃縮装置より
発生した酸素濃縮空気を部屋に導くことにより高
酸素濃度雰囲気が作られる。 In this way, a high oxygen concentration atmosphere is created by introducing oxygen-enriched air generated from an oxygen concentrator using a selective adsorbent into the room.

There is. Therefore, regardless of whether the oxygen enricher is installed indoors, outdoors, or at the interface between the two, atmospheric air flows from the outdoors to the intake of the oxygen enricher.
The nitrogen-enriched air discharged from the outlet may be installed and piped so as to be introduced into the room.
