Description

과산화수소수 분해를 이용한 산소발생 가습기Oxygen Generating Humidifier Using Hydrogen Peroxide Decomposition
본 발명은 과산화수소수를 열분해하여 얻어지는 산소와 수증기를 함께 배출하는 산소발생 가습기에 관한 것으로서, 특히 과산화수소수 저장통의 입구가 과산화수소수 분해기로 연결된 유로에 대해 하방을 향하도록 연결되어 있기 때문에 부가적인 액체펌프 등의 구성 없이도 열분해되는 과산화수소수의 양만큼 자동으로 과산화수소수가 공급되는 구조를 갖는 산소발생 가습기에 관한 것이다.The present invention relates to an oxygen generating humidifier for discharging oxygen and water vapor obtained by thermally decomposing hydrogen peroxide, and in particular, because the inlet of the hydrogen peroxide reservoir is connected downward to the flow path connected to the hydrogen peroxide decomposer. The present invention relates to an oxygen generating humidifier having a structure in which hydrogen peroxide water is automatically supplied by the amount of hydrogen peroxide water that is pyrolyzed without the configuration.
최근 대기 오염이 심해지고, 냉난방기의 보급에 따라 밀폐된 공간에서 주거하는 시간이 많아졌으며, 건강에 대한 관심이 증가함에 따라, 산소발생기가 주목을 받고 있다.In recent years, air pollution has become more severe, and in accordance with the spread of air conditioners, the time to dwell in an enclosed space has increased, and as interest in health increases, oxygen generators have attracted attention.
이러한 산소발생기에 적용할 수 있는 종래의 산소 발생방법으로는 1) 공기 중의 산소 기체에 대한 투과율이 그 외의 기체에 대한 투과율보다 높은 산소부화막 등의 얇은 막을 이용하여 통상의 공기에 비해 산소 농도가 높은 공기를 공급하는 방법, 2) 공기 중의 산소 이외의 가스에 대한 선택적 흡착성이 높은 제올라이트 등의 흡착제를 이용하여 통상의 공기에 비해 산소 농도가 높은 공기를 공급하는 방법, 3) 과산화수소 부가물을 주성분으로 하는 액체에 심지를 설치하고 모세관 현상을 이용하여 심지의 상부로 상기 액체를 공급하여 가열 증발시키면서 화학적으로 분해하여 산소를 발생시키는 방법, 4) 과산화수소 부가물과 효소 등을 주성분으로 하는 고체 분말을 물과 혼합할 때 일어나는 화학반응을 이용하여 산소를 발생시키는 방법 등이 주류를 이루고 있고, 이외에도 5) 통상적인 가열수단에 의한 열을 이용하여 과산화수소를 고온에서 분해하는 방법 또는 6) 촉매를 이용하여 과산화수소를 분해하는 방법 등이 공지되어 있다.Conventional oxygen generating methods applicable to such oxygen generators include: 1) using a thin film such as an oxygen enrichment membrane having a higher permeability to oxygen gas in air than a permeation rate to other gases. 2) A method of supplying high air, 2) A method of supplying air having a higher oxygen concentration than ordinary air by using an adsorbent such as zeolite having a high selective adsorption to a gas other than oxygen in the air, and 3) The main component of hydrogen peroxide adduct. Wick is installed in the liquid, and the capillary phenomenon is used to supply the liquid to the upper part of the wick to chemically decompose while heating and evaporating to generate oxygen. 4) A solid powder mainly composed of hydrogen peroxide adducts and enzymes, etc. The process of generating oxygen using a chemical reaction that occurs when mixing with water is the mainstream. In addition, 5) a method of decomposing hydrogen peroxide at high temperature using heat by conventional heating means, or 6) a method of decomposing hydrogen peroxide using a catalyst is known.
상기의 방법들 중에서 상기 1) 또는 2)의 방법은 공기 중에 포함되어 있는 산소를 농축하는 방법으로서, 엄밀한 의미에서는 산소발생방법이 아닌 산소농축방법이며, 산소 함량이 낮은 기체가 부산물로서 생성되므로 이것을 배출하기 위한 실외기의 설치가 필요할 뿐 아니라 인체에 유익하지 않은 부산물 기체를 실외로 배출하는데 따르는 2차 공해 또는 소음이 발생될 우려가 있고, 90% 이상의 고농도 산소를 발생시키기 어렵다는 문제점이 있다.Among the above methods, the method of 1) or 2) is a method of concentrating oxygen contained in air, and in an exact sense, it is not an oxygen generation method but an oxygen concentration method, and since a gas having a low oxygen content is generated as a by-product, In addition to the need for installation of an outdoor unit to discharge, there is a concern that secondary pollution or noise caused by discharging the by-product gas that is not beneficial to the human body to the outside may occur, and it is difficult to generate high concentration oxygen of more than 90%.
상기 3) 또는 4)의 방법은 산소를 자체적으로 발생시키는 방법이므로, 상기의 2차 공해의 문제는 없으나, 3)의 경우는 산소의 발생량이 미미하여 적용에 한계가 있다는 문제점이 있고, 특히 4)의 방법은 산소 발생 지속 시간이 수 분 정도로 짧아서 지속적으로 산소를 발생시킬 수 없다는 문제점이 있다.Since the method of 3) or 4) generates oxygen by itself, there is no problem of the secondary pollution, but in the case of 3), there is a problem in that the amount of oxygen is insignificant and there is a limit in application. The method has a problem in that the oxygen generation duration is short enough to generate oxygen continuously.
또한, 상기 5)의 방법은 과산화수소의 분해 효율이 낮아서 미분해 상태인 대부분의 과산화수소가 외부로 배출되는 경우 과산화수소의 자극적인 냄새의 독성 성분으로 인하여 인체에 유해하다는 문제점이 있다. 그리고 상기 6)의 방법에서는 활성이 강력한 촉매(예를 들면, 이산화망간 등)를 사용하면 과산화수소는 단시간에 폭발적으로 분해되어 버리고, 활성이 약한 촉매(예를 들면, 숯 및 활성탄 등)를 사용하면 과산화수소의 분해반응이 매우 미약하게 진행되므로, 어느 경우에나 소정의 산소발생량을 장시간 일정하게 유지할 수 없다는 문제점이 있다.In addition, the method of 5) has a problem in that the decomposition efficiency of hydrogen peroxide is low and harmful to the human body due to the toxic components of the irritating smell of hydrogen peroxide when most of the hydrogen peroxide which is undecomposed is discharged to the outside. In the method of 6), hydrogen peroxide decomposes explosively in a short time when a catalyst having a strong activity (for example, manganese dioxide) is used, and hydrogen peroxide is used when a catalyst having a weak activity (for example, charcoal and activated carbon) is used. Since the decomposition reaction proceeds very weakly, there is a problem that the predetermined amount of oxygen cannot be kept constant for a long time in any case.
이에 본 출원인은 종래기술의 문제점들을 효율적으로 해결한 한국등록특허 제773121호의 "과산화수소 분해기 및 이것을 이용한 산소발생기"를 발명하였으며, 이 산소발생기의 구성은 도 1에 도시되어 있다.Accordingly, the present applicant has invented the "hydrogen peroxide decomposer and oxygen generator using the same" of Korean Patent No. 773121, which effectively solves the problems of the prior art, the configuration of the oxygen generator is shown in FIG.
도 1에 도시된 선행특허는 내부에 발포 알루미늄, 지르코니아볼, 알루미나볼, 망상의 스텐레스강, 알루미늄, 탄탈 및 지르코늄으로 이루어진 군으로부터 선택되는 과산화수소 분해용 금속제 충전재가 충전되고 히터가 구비된 과산화수소 분해기(14)를 포함하는 산소발생기(10)인데, 과산화수소 분해기(14)는 이에 연결된 과산화수소수 저장조(12)로부터 공급되는 과산화수소수(11)를 산소기체와 수증기로 분해한다. 그리고 배출되는 수증기는 소정량의 물이 채워져 있는 분리조(18)에서 기-액 분리됨으로써 산소기체만이 기포 형태로 외부로 배출된다. 또한 습도 조절을 위한 가습부(19)를 더 포함할 수 있는데, 가습부(19)는 분리조(18)로부터 배출되는 물을 가열 또는 초음파 진동 등을 이용해 무화시킨다.1 shows a hydrogen peroxide decomposer filled with a metal filler for hydrogen peroxide decomposition selected from the group consisting of expanded aluminum, zirconia balls, alumina balls, reticulated stainless steel, aluminum, tantalum and zirconium. It is an oxygen generator 10 comprising a 14), the hydrogen peroxide decomposer 14 decomposes hydrogen peroxide 11 supplied from the hydrogen peroxide storage tank 12 connected thereto with oxygen gas and water vapor. The discharged water vapor is gas-liquid separated in the separation tank 18 filled with a predetermined amount of water so that only the oxygen gas is discharged to the outside in the form of bubbles. In addition, the humidity control unit may further include a humidification unit 19. The humidifying unit 19 atomizes the water discharged from the separation tank 18 by heating or ultrasonic vibration.
그 밖에 산소발생기(10)의 구동을 중단하는 경우에 분해기(14) 내부의 온도가 감소됨에 따라 기체의 수축으로 분리조(18) 내부의 물이 과산화수소 분해기(14)로 역류할 가능성을 차단하기 위해 분리조(18) 입구에 저수통과 같은 역류방지부재(16)가 설치될 수 있으며, 산소기체가 기-액 분리되는 분리조(18)의 수온이 물의 비등점 이상으로 과다하게 높아지면 물이 끓는 소리로 인한 소음 발생이 문제되므로 과산화수소 분해기(14)와 분리조(18) 사이에 수증기(또는 물)를 냉각시키기 위한 별도의 냉각장치(15)가 설치될 수 있다.In addition, when the operation of the oxygen generator 10 is stopped, the temperature inside the decomposer 14 decreases to block the possibility that water inside the separation tank 18 flows back to the hydrogen peroxide decomposer 14 due to contraction of gas. In order to prevent the backflow member 16, such as a reservoir, at the inlet of the separation tank 18, if the water temperature of the separation tank 18 in which the oxygen gas is gas-liquidly separated becomes excessively higher than the boiling point of water, Since the noise generated by the boiling sound is a problem, a separate cooling device 15 for cooling water vapor (or water) may be installed between the hydrogen peroxide decomposer 14 and the separation tank 18.
이와 같은 구성을 가진 도 1의 산소발생기는 과산화수소 분해 촉진용 충전재의 교체 없이도 과산화수소의 완전분해가 가능하고, 고순도의 산소를 장시간 지속적으로 발생시킬 수 있으며, 산소의 발생량을 용이하게 제어할 수 있다는 점 등에 있어서 종래의 산소발생기에 비해 우수한 성능을 가진다.The oxygen generator of FIG. 1 having such a configuration can completely decompose hydrogen peroxide without replacing the hydrogen peroxide decomposition promoting filler, can generate high purity oxygen continuously for a long time, and can easily control the generation of oxygen. It has superior performance in comparison with the conventional oxygen generator.
그렇지만 위 산소발생기는 기본적으로 액체펌프(13A)로 과산화수소수를 과산화수소 분해기(14)에 압송하고, 분리조(18)의 구성을 구비함에 따라 부수적으로 냉각장치(15)와 역류방지부재(16)가 필요하며, 가습부(19)가 추가될 경우 물을 공급하기 위한 또 하나의 액체펌프(13B)와 초음파 진동판 등의 무화수단이 더 필요해진다. 즉 산소 및/또는 수분을 공급하는 구성이 다소 복잡해지기 때문에, 탁상에서 개인용으로 사용하기에는 가격이 다소 비싸고 유지·보수가 쉽지 않은 단점이 있다.However, the oxygen generator is basically a liquid pump (13A) to pressurize the hydrogen peroxide water to the hydrogen peroxide decomposer (14), and as a constitution of the separation tank 18, incidentally the cooling device 15 and the backflow prevention member (16) When the humidifying unit 19 is added, another liquid pump 13B and an atomization means such as an ultrasonic diaphragm for supplying water are needed. That is, since the configuration for supplying oxygen and / or moisture becomes more complicated, there is a disadvantage that the price is rather expensive and not easy to maintain and maintain for personal use on the table.
또한 도 1의 산소발생기는 35% 정도의 농도를 갖는 과산화수소수를 열분해하는 것을 상정한 장치인데, 이런 정도의 고농도 과산화수소수는 위험물 또는 유독물로 취급되기 때문에 개인이 구입하여 사용하기에는 적당하지 않다는 점에서도 개인용 산소발생기로서는 한계가 있다.In addition, the oxygen generator of FIG. 1 is assumed to pyrolyze hydrogen peroxide water having a concentration of about 35%, and this high concentration of hydrogen peroxide water is treated as a dangerous or toxic material, so it is not suitable for individual purchase and use. There is a limit as a personal oxygen generator.
따라서 본 발명은 선행특허 제773121호에 포함된 액체펌프나 분리조, 냉각장치와 가습부, 그리고 역류방지부재 등의 복잡한 구성을 모두 생략한 단순한 구조를 가짐으로써 생산이 용이하고 가격 역시 저렴하여 개인용으로 사용하기에 적합한 과산화수소수 분해를 이용한 산소발생 가습기를 제공하는 것에 그 목적이 있다.Therefore, the present invention has a simple structure that omits all the complicated configurations such as the liquid pump or the separation tank, the cooling device and the humidification unit, and the backflow prevention member included in the prior patent No. 773121 is easy to produce and the price is also low It is an object of the present invention to provide an oxygen generating humidifier using hydrogen peroxide decomposition suitable for use as a.

도 2는 본 발명에 따른 산소발생 가습기(1)의 전체적인 구성을 보여주는 도면이다. 도시된 바와 같이, 본 발명의 산소발생 가습기(1)는 가습기 본체(100), 과산화수소수 분해기(200), 과산화수소수 저장통(300) 및 전원장치(400)를 포함한다.2 is a view showing the overall configuration of the oxygen generating humidifier 1 according to the present invention. As shown, the oxygen generating humidifier 1 of the present invention includes a humidifier body 100, a hydrogen peroxide decomposer 200, a hydrogen peroxide water reservoir 300 and a power supply 400.
가습기 본체(100)는 다른 구성요소, 즉 과산화수소수 분해기(200)와 과산화수소수 저장통(300) 및 전원장치(400)가 결합되는 부분인데, 특히 과산화수소수 주입구(110) 및 산소/수증기 배출구(120)를 구비하고 있고, 또한 주입구(110) 및 배출구(120)를 연결하는 유로(130)가 구비되어 있다. 이 유로(130)는 주입구(110)와 배출구(120)를 연결하는 호스로 구성될 수 있다.The humidifier main body 100 is a part to which other components, that is, the hydrogen peroxide decomposer 200, the hydrogen peroxide storage tank 300 and the power supply 400, in particular, the hydrogen peroxide water inlet 110 and the oxygen / vapor outlet 120 ), And a flow path 130 connecting the inlet 110 and the outlet 120 is provided. The flow path 130 may be configured as a hose connecting the inlet 110 and the outlet 120.
그리고 과산화수소수 분해기(200)는 과산화수소수(320)를 가열하여 2H2O2 → 2H2O + O2 로 분해시켜 산소와 물(수증기)을 만들어내는 부분이다. 이 과산화수소수 분해기(200)는 히터(210) 및 히터(210)에 의해 가열되는 분해촉진기(220)를 포함하는 구성을 가지며, 유로(130) 상에 설치되어 연속적으로 공급되는 과산화수소수(320)를 열분해하여 산소/수증기 배출구(120)로 산소와 수증기를 동시에 배출한다. 따라서 본 발명은 초음파 진동판과 같은 별도의 가습부가 필요 없고, 기-액 분리조 등과 같은 구성도 필요치 않다. Hydrogen peroxide decomposer 200 is a part that generates hydrogen and water (steam) by heating hydrogen peroxide 320 to decompose into 2H 2 O 2 → 2H 2 O + O 2 . The hydrogen peroxide decomposer 200 has a configuration including a heater 210 and a decomposition accelerator 220 that is heated by the heater 210, and is installed on the flow path 130 to supply hydrogen peroxide 320 continuously. Pyrolysis to simultaneously discharge oxygen and water vapor to the oxygen / steam outlet 120. Therefore, the present invention does not require a separate humidifying part such as an ultrasonic diaphragm, and does not require a configuration such as a gas-liquid separation tank.
히터(210)는 전원장치(400)로부터 전기에너지를 공급받아 열에너지로 변환시키는 구성이며, 이 열에너지는 과산화수소수(320)에 직접 접촉되는 분해촉진기(220)로 전달된다. 히터(210)의 가열온도는 100∼400℃인 것이 바람직한데, 이런 히터(210)의 온도범위는 실제 분해촉진기(220)에서의 온도가 과산화수소수(320)의 열분해에 적합한 온도를 가지도록 하기에 적합하다.The heater 210 is configured to receive electrical energy from the power supply device 400 and convert the electrical energy into thermal energy, and the thermal energy is transferred to the decomposition promoter 220 which is in direct contact with the hydrogen peroxide water 320. The heating temperature of the heater 210 is preferably 100 ~ 400 ℃, such that the temperature range of the heater 210 so that the actual temperature in the decomposition accelerator 220 has a temperature suitable for the thermal decomposition of the hydrogen peroxide (320) Suitable for
분해촉진기(220)는 과산화수소수(320)와 반응하지 않는 소재로 이루어지는데, 특히 체적에 비해 표면적이 넓도록 함으로써 과산화수소수(320)와의 접촉면적을 키워 열분해를 촉진하는 형상을 갖는 것이 바람직하다. 예를 든다면, 망상구조를 갖거나 또는 다수 입자의 집합체로 구성될 수 있다.The decomposition accelerator 220 is made of a material that does not react with the hydrogen peroxide 320, in particular, it is preferable to have a shape that promotes thermal decomposition by increasing the contact area with the hydrogen peroxide 320 by making the surface area wider than the volume. For example, it may have a network structure or be composed of an aggregate of a plurality of particles.
본 발명의 실시예에서, 분해촉진기(220)로는 발포 알루미늄, 망상의 스텐레스강, 알루미늄, 탄탈 및 지르코늄으로 이루어진 군으로부터 선택되는 과산화수소 분해용 금속제 충전재일 수 있다.In the embodiment of the present invention, the decomposition accelerator 220 may be a metal filler for hydrogen peroxide decomposition selected from the group consisting of foamed aluminum, mesh stainless steel, aluminum, tantalum and zirconium.
또한 분해촉진기(220)는 금속재질 이외에도 과산화수소수(320)와 반응하지 않는 세라믹 재질도 가능하며, 구체적으로는 망상의 세라믹 또는 세라믹볼의 형상을 가질 수 있다.In addition, the decomposition accelerator 220 may be a ceramic material that does not react with the hydrogen peroxide 320 in addition to the metal material, and specifically may have a shape of a network ceramic or ceramic ball.
과산화수소수 분해기(200)로 공급되는 과산화수소수(320)는 과산화수소수 주입구(110)에 연결되는 과산화수소수 저장통(300) 안에 소정량 저장된다. 특히 본 발명은 과산화수소수 저장통(300)의 입구(310)가 과산화수소수 주입구(110)에 대해 하방을 향하도록 결합되는데, 이에 따라 본 발명은 별도의 액체펌프 없이도 과산화수소수 분해기(200)에서 열분해로 소모된 양만큼의 과산화수소수(320)가 연속적으로 공급될 수 있다. 이러한 구조의 장점은 단순하면서도 과산화수소수 분해기(200)의 열분해 용량에 따라 자동으로 공급량이 맞춰지게 되며, 과산화수소수 분해기(200)가 식더라도 과산화수소수(320)가 역류할 염려가 없어 역류방지부재와 같은 복잡한 부대구성이 필요치 않다는 것이다.The hydrogen peroxide water 320 supplied to the hydrogen peroxide decomposer 200 is stored in a hydrogen peroxide storage container 300 connected to the hydrogen peroxide water inlet 110. In particular, the present invention is coupled so that the inlet 310 of the hydrogen peroxide storage container 300 is directed downward toward the hydrogen peroxide water inlet 110, according to the present invention is pyrolysis in the hydrogen peroxide decomposition device 200 without a separate liquid pump As much as the consumed amount of hydrogen peroxide water 320 may be continuously supplied. The advantages of this structure are simple, but the supply amount is automatically adjusted according to the pyrolysis capacity of the hydrogen peroxide decomposer 200, even if the hydrogen peroxide decomposer 200 cools, there is no fear that the hydrogen peroxide 320 will flow back, and the backflow prevention member and The same complex configuration is not necessary.
그리고 전원장치(400)는 과산화수소수 분해기(200)의 히터(210)에 전원을 공급하는 구성으로서, 건전지와 같은 내부전원도 가능하지만 전열기구인 히터(210)의 전력소모량을 고려한다면 콘센트로 공급되는 외부전원을 적용하는 것이 바람직할 것이다.In addition, the power supply unit 400 is configured to supply power to the heater 210 of the hydrogen peroxide decomposer 200, and internal power such as a battery may be used, but considering the power consumption of the heater 210 which is a heating device, It would be desirable to apply an external power source.
이때 과산화수소수 저장통(300)으로부터 과산화수소수 분해기(200)로 연결되는 상기 유로(130)에는 그 안의 과산화수소수(320)의 수위가 사전에 설정된 하한치에 도달했는지를 감지하는 레벨센서(140)가 더 포함될 수 있다. 그리고 레벨센서(140)가 설정된 하한치를 감지하면 히터(210)에 공급되는 전원을 차단함으로써 과산화수소수(320)의 소진에 의한 히터(210)의 과열을 방지할 수 있다. 레벨센서(140)는 유로(130) 안의 과산화수소수(320)의 수위가 하한치에 도달했는지만을 판단하면 충분하기 때문에 수위가 어느 레벨에 있는지를 연속적으로 측정할 필요는 없으며, 예를 들어 유로(130)의 일정 지점(=수위의 하한치 지점)에 레벨센서(140)를 설치하고 그 설치 위치 아래로 수위가 떨어졌는지만 판단할 수 있으면 충분하다.At this time, in the flow path 130 connected to the hydrogen peroxide decomposer 200 from the hydrogen peroxide water reservoir 300, a level sensor 140 for detecting whether the water level of the hydrogen peroxide 320 therein has reached a preset lower limit is further included. May be included. When the level sensor 140 senses the set lower limit value, the power supply to the heater 210 is cut off to prevent overheating of the heater 210 due to exhaustion of the hydrogen peroxide water 320. Since the level sensor 140 only needs to determine whether the level of the hydrogen peroxide 320 in the flow path 130 has reached the lower limit, it is not necessary to continuously measure which level the water level is at, for example, the flow path 130. It is sufficient if the level sensor 140 is installed at a certain point (= lower limit point of the water level) and the water level has dropped below the installation position.
그리고 과산화수소수 저장통(300)은 시중에 유통되는 PET 용기 중의 어느 하나를 사용할 수도 있다. 음료용기로 사용되는 PET 용기의 마개부 나사규격은 KS 규격으로 표준화되어 있지는 않지만 통상적으로 널리 쓰이는 규격은 있으므로, 이런 보편적인 규격에 맞춰 과산화수소수 주입구(110)를 형성하거나 별도의 연결구를 사용하여 결합시키는 것이 가능하다. 시중에 유통되는 PET 용기를 과산화수소수 저장통(300)으로 사용하면 생산원가 절감에 도움이 되며, 과산화수소수 저장통(300)을 세척하여 사용할 필요 없이 적당한 기간 동안만 사용한 후 교체하여 사용할 수 있다는 점에서 편리하다.And the hydrogen peroxide storage container 300 may use any one of the PET containers in the market. The stopper screw standard of PET container used as beverage container is not standardized by KS standard, but there is a widely used standard, so the hydrogen peroxide water inlet 110 is formed in accordance with this universal standard or combined using a separate connector. It is possible to let. The use of commercially available PET containers as the hydrogen peroxide reservoir 300 helps to reduce production costs, and is convenient in that the hydrogen peroxide reservoir 300 can be used after only a suitable period of time without being washed and used. Do.
한편 상기 과산화수소수(320)의 농도는 5.9% 이하인 것이 바람직하다. 5.9% 이하 농도의 과산화수소수(320)는 일반물로 시판되기 때문에 개인이 용이하게 입수하기 쉽다. 참고로 약국에서 소독용으로 판매하는 과산화수소수는 3∼5% 농도를 갖는다. 이에 비해 6∼34.9% 농도의 과산화수소수는 위험물로 취급되고, 35% 농도 이상의 과산화수소수는 유독물로 관리되기 때문에 일반 개인이 사용하기에는 제한이 따른다.On the other hand, the concentration of the hydrogen peroxide 320 is preferably 5.9% or less. Hydrogen peroxide water 320 at a concentration of 5.9% or less is easily available to individuals because it is commercially available. For reference, the hydrogen peroxide solution sold at the pharmacy for disinfection has a concentration of 3-5%. On the other hand, 6 to 34.9% hydrogen peroxide water is treated as dangerous goods, and more than 35% hydrogen peroxide water is managed as a toxic substance, so there is a limit for use by the general public.
또한 5.9% 농도의 과산화수소수(320)라도 액체부피의 약 20배의 100% 산소가 만들어지기 때문에 산소공급원으로서 충분한 효과를 얻을 수 있다는 점에서 본 발명의 실시예에 적용되기에 적합하다.In addition, even in the case of hydrogen peroxide 320 having a concentration of 5.9%, since 20% of the liquid volume is made of 100% oxygen, it is suitable for the embodiment of the present invention in that a sufficient effect can be obtained as an oxygen source.
이상 도면에 도시된 실시예를 참고로 하여 본 발명이 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 기술적 보호범위는 특허청구범위에 의해서 정하여져야 할 것이다.Although the present invention has been described with reference to the embodiments shown in the drawings, it is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims.
