Description

The oxygen generation module and the manufacturing method thereof using respiration

The present invention relates to an oxygen generation module using respiration and a manufacturing method thereof, and more particularly, CO ₂ and H ₂ O generated during respiration and KO ₂ filled in a cartridge, Ca(OH) ₂ , LiOH, porous silica, etc. It relates to an oxygen generation module using respiration capable of generating and controlling oxygen by using and a manufacturing method thereof.

Oxygen is the most abundant element on Earth and is most often dissolved in water. A person breathes about 15 kg of air a day, and a very large amount is needed, about 250 to 500 liters in terms of volume. A typical symptom of oxygen deficiency is a headache. Headache has many causes, but the biggest cause is lack of oxygen. The brain uses more than 30% of total oxygen consumption. Therefore, if you are under a lot of stress or have a lot of nerves, the consumption of oxygen increases, and when it becomes difficult to supply it, a headache occurs. In addition, if you consume a lot of energy, you often yawn to replenish oxygen. For this oxygen supply, about 2,000 liters of blood go to the brain during the day, which is about 400 times the total blood volume. The concentration of oxygen in the air is also important. If the oxygen concentration falls below 20.5%, you will feel a headache.

As the use of masks has become mandatory in countries around the world due to the coronavirus pandemic, the use of masks has become mandatory not only for medical staff but also for the general public. In addition, as the mask use time increases, research papers are being published that headaches and oxygen deprivation of the brain are occurring due to an increase in CO ₂ and lack of oxygen.

Oxygen production technology has the following methods. There are physical methods for separating oxygen from air and chemical methods using chemical reactions. Physical methods for separating oxygen from air include cryogenic distillation, membrane separation, and pressure swing adsorption (PSA).

Cryogenic distillation is a method of separating O ₂ , N ₂ , and Ar by liquefying and distilling air. Disadvantages are that large equipment is required, and liquid oxygen evaporates over time.

Membrane separation is a technology that selectively separates O ₂ , N ₂ , and Ar in the air by using a difference in the permeation rate of materials through the hollow fiber membrane using a membrane, and injecting compressed air into the hollow fiber membrane to release oxygen from the hollow fiber membrane. It releases oxygen by letting it come out. This method is a structure that can be used semi-permanently, and is easy to install and has a wide range of uses. It is strong against moisture and has no reaction with other media, so it is a great advantage that there is almost no repair. It is mainly used for industrial purposes. The disadvantage is that the specific surface area of the membrane must be wide for high-speed production, and when the pressure is high, stability problems and a large-capacity compressor are required. In addition, since the sizes of oxygen molecules and argon molecules are similar, there is a problem in that the purity of oxygen is low.

The pressure swing adsorption method (PSA) is a method to separate oxygen from air by injecting compressed air into two adsorption towers filled with adsorbents such as zeolite and nanotubes to adsorb nitrogen and argon and pass only oxygen to increase the concentration of oxygen. , which is currently the most used. However, the raw material used as an adsorbent is weak against moisture, so there remains a disadvantage that great attention must be paid to moisture prevention.

Chemical oxygen generating technology is a technology that generates oxygen by chemical reaction, and superoxide, chloric acid, and perchloric acid are mainly used as oxygen generating sources.

Chloric acid and perchloric acid: Chloric acid (LiClO ₃ , NaClO ₃ , KClO ₃ ) and perchloric acid (LiClO ₄ , NaClO ₄ , KClO ₄ ) containing Li, Na, and K are put into a cylinder together with iron powder to form a perchloric acid candle or an oxygen candle. do. When these oxygen candles are ignited, oxygen is generated by the reaction of 2NaClO ₃ -> 2NaCL + 3O ₂ . The generated oxygen is filtered by the filter and transported to the mask through a hose to be inhaled by the user. The solid oxygen candle consists of a block of sodium chlorate packed inside an insulated stainless steel housing to control the heat generated when activated. There are spring operated ignition pin ignition method and induction electric high temperature electric ignition method. Once ignited, the solid chlorine oxygen generation module cannot be digested and generally generates breathable oxygen for 10 to 20 minutes. The use of solid oxygen can significantly increase costs because it must be replaced once used. Moreover, chemical oxygen cans are hazardous materials and require special care and must be properly packaged and inactivated when transported.

Superoxide, Superoxide: Potassium superoxide KO ₂ has been used in mines, firefighters, high altitude mountaineering, submarines and spacecraft. Superoxides (NaO ₂ , Ca(O ₂ ) ₂ ) and peroxides (Li ₂ O ₂ , Na ₂ O ₂ ) can be used instead of KO ₂ , but KO ₂ is mainly used due to reactivity, stability and sample preparation problems. . When the package containing KO ₂ connected to the mask is opened in an emergency situation where oxygen is needed, oxygen is generated by CO ₂ and moisture by exhalation, and oxygen generated in this way is inhaled by inhalation. At this time, the reaction is rapid, and the inhaled air is extremely hot and dry, resulting in difficulty in breathing.

As another method, the oxygen generation method using a catalyst is a principle of generating oxygen by reacting with water with a catalyst using a bleach, and has a very simple structure and generates high-purity oxygen. However, it has a disadvantage that the catalyst must be exchanged every time. In addition, the electrolysis method is the principle of generating oxygen and hydrogen by electrolysis of water. It has a very simple structure and is the most basic and most open technology as a method of generating high-purity oxygen, but it is not commercially used. The post-processing process is complicated because highly explosive hydrogen is generated, which is dangerous and requires separate treatment of hydrogen.

The present invention is a device capable of inhaling oxygen by oral respiration, and is characterized by a CO ₂ adsorbent and a material and structure capable of controlling moisture so as to suppress a rapid reaction and supply oxygen constantly.

[Principle of Oxygen Generation]

The principle of oxygen generation and CO ₂ adsorption using potassium peroxide (KO ₂ ) is represented by the following three equations. KO ₂ reacts with water (H ₂ O) in the air to generate KOH and O ₂ , and KOH reacts with carbon dioxide (CO ₂ ) in the air to generate K ₂ CO ₂ , KHCO ₃ and H ₂ O. This reaction is repeated until all KO ₂ are consumed.

2KO ₂ + H ₂ O --> 2KOH + 1.5O ₂ + Q

2KOH + CO ₂ --> K ₂ CO ₃ + H ₂ O + Q

KOH + CO ₂ --> KHCO ₃ + Q

Oxygen masks used in emergency situations contain potassium superoxide, KO ₂ . Potassium superoxide reacts with carbon dioxide and water vapor in the exhaled breath to generate oxygen. At this time, potassium bicarbonate, which is not harmful to the human body, is also produced. When a person exhales, the chemical reaction with potassium superoxide is as follows: 4KO ₂ + 2H ₂ O + 4CO ₂ → 4KHCO ₃ + 3O ₂

If a person wearing an oxygen mask breathes out 0.70 g of carbon dioxide per minute, then an hour's oxygen mask must contain at least 68 g of potassium superoxide. That is, it has the disadvantage of requiring a large amount of potassium superoxide and thus requires a retardant (regulator).

Therefore, per hour is 1.1309g KO ₂ * 60 min = 68g KO ₂ (per hour)

A person wearing an oxygen mask exhaling 0.702 g of carbon dioxide per minute can produce 1.92 g of oxygen in 5 minutes if the material is sufficient.

Therefore, 0.383 g O ₂ * 5 min = 1.92 g O ₂ at 5 min.

[CO ₂ adsorption principle]

Lithium hydroxide (LiOH) has been used as a CO ₂ adsorbent, and LiOH reacts with H ₂ O and CO ₂ as follows.

2LiOH + 2H ₂ O --> 2LiOH * H ₂ O

2LiOH*H ₂ O + CO ₂ --> Li ₂ CO3 + 3H ₂ O

LiOH requires water vapor to initiate CO ₂ adsorption, and the water vapor generated in the second reaction can be consumed again in the first reaction. Some water vapor will be present in the bed to continue adsorption of CO ₂ .

[Principle of moisture control]

Silica gel can be used for moisture control. Silica gel releases moisture when the humidity is low and absorbs moisture when the ambient humidity is high, so that the ambient humidity can be controlled. The silica gel used is grade 44, 3-8 mesh.

The oxygen generation module and manufacturing method using respiration according to the present invention are as follows. Potassium superoxide (KO ₂ ), granular powder, and LiOH, which are starting materials, are each molded into a cylindrical shape using a uniaxial press, and silica gel is separately put into a cartridge and arranged. Alternatively, these starting materials are mixed together to form a cylinder formed by a single screw press.

<Example 1>

5 g of potassium peroxide powder (KO ₂ ) is weighed and a cylindrical molded body having a diameter of 12 mm is prepared using a uniaxial press, and then put into a cartridge to produce an oxygen generating module.

<Example 2>

After weighing and mixing 5 g of potassium peroxide powder (KO ₂ ) and 2 g of adsorbent Ca(OH) ₂ , a cylindrical molded body having a diameter of 12 mm is prepared using a single screw press, and then inserted into a cartridge to produce an oxygen generating module.

<Example 3>

After weighing and mixing 5g of potassium peroxide powder (KO ₂ ), 2g of adsorbent Ca(OH) ₂ and 2g of silicone resin, a cylindrical molded body with a diameter of 12mm is prepared using a single screw press, and then inserted into a cartridge to produce an oxygen generating module. do.

<Example 4>

In Example 3, the silicone resin, the adsorbent, and the potassium peroxide are each manufactured in a cylindrical shape and arranged in series to manufacture an oxygen generating module.

<Example 5>

An oxygen generation module composed of potassium superoxide and silica gel was fabricated, and the relative humidity change and oxygen generation delay according to the thickness of the silica gel (1X, 2X, 3X) are shown in FIG. 5. It can be seen that oxygen generation is delayed as the thickness of the silica gel increases. In addition, it can be seen that the relative humidity decreases as the thickness of the silica gel increases.

<Example 6>

An oxygen generation module composed of potassium superoxide and lithium hydroxide was manufactured, and the change in CO ₂ concentration and the delay in oxygen generation according to the thickness of lithium hydroxide (1X, 2X, 3X) are shown in FIG. 6 . It can be seen that as the thickness of lithium hydroxide increases, oxygen generation is delayed. In addition, it can be seen that the CO ₂ concentration decreases as the thickness of the lithium hydroxide increases.

<Example 7>

An oxygen generating module composed of only potassium superoxide and an oxygen generating module composed of lithium hydroxide, silica gel and potassium superoxide were fabricated, and the change in oxygen generation rate is shown in FIG. 7 . The rate of oxygen generation can be controlled by adding lithium hydroxide and silica gel and adjusting the length. That is, in the case of an oxygen generating module composed of potassium superoxide alone, there is a limit to adjusting the oxygen generating rate, but in the case of an oxygen generating module composed of lithium hydroxide, silica gel and potassium superoxide, the oxygen generating rate is controlled by adjusting the two limits (length). can be adjusted. Therefore, the present invention proposes an oxygen generating module composed of lithium hydroxide, silica gel and potassium superoxide instead of an oxygen generating module composed of potassium superoxide alone.
