Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an oxygen generating device that generates oxygen by decomposing hydrogen peroxide using a catalyst.

[Background of the invention] Generally, angina pectoris, myocardial infarction, asthma, emphysema.

Oxygen inhalation is said to be effective against heart attacks caused by lung cancer, Kawasaki disease, etc. This is especially important as we age, and oxygen inhalation is said to be effective in recovering from fatigue after sports or hard labor, and in activating a tired brain.

For this reason.

Various oxygen generators are being developed.

However, all of these methods are expensive, generate only a small amount of oxygen, and take only a short time to generate oxygen.

There have been various problems such as the inability to increase or decrease the amount of oxygen generated, the generation being interrupted midway through generation, and the generation being unable to be restarted.

[Purpose of the invention]

The present invention is intended to solve the various problems mentioned above.It uses hydrogen peroxide, which is available at a low price, as a generation source, generates a large amount of oxygen, and can be ordered continuously for a long time. It is an object of the present invention to provide an oxygen generating device that can not only freely adjust the amount of oxygen generated depending on the situation, but also can interrupt oxygen generation midway through and restart oxygen generation. Another object of the present invention is to provide a highly convenient oxygen generator that can be attached as is without the need to replace the hydrogen peroxide bottle with another supply tray or the like.

[Structure of the invention]

In order to achieve the above object, the present invention provides an oxygen generating device that generates oxygen through a decomposition reaction of hydrogen peroxide using a catalyst; A supply means for dropping hydrogen peroxide onto the powdered catalyst housed in the decomposition reaction cylinder, and a cooler for cooling water vapor oxygen generated in the decomposition reaction cylinder and dissipated from the cylinder wall, are provided. It is constructed so that it can be obtained at low cost.

Incidentally, it is known that oxygen is generated by a decomposition reaction of hydrogen peroxide using a catalyst.

The situation in which it occurs varies greatly depending on the concentration of hydrogen peroxide and the degree of activation of the catalyst.

In the case of the present invention.

329 (!l 41), it is a strong exothermic reaction, but if you drop natural manganese dioxide powder with low activation into hydrogen peroxide at an extremely low concentration of about 5%, as in the curriculum guidelines for elementary and junior high schools. , it gradually decomposes and generates oxygen, but the heat generated is absorbed by the 95% large amount of diluted water, and the decomposition reaction is so gentle that there is hardly any temperature rise of the decomposed water and the generated oxygen gas.

In addition, on top of the highly purified and highly activated manganese dioxide powder obtained by electrolysis, a relatively high concentration of 35% hydrogen peroxide (noodles), which is widely commercially available as a food additive, is added.

For bleaching fish for surimi, pickled vegetables, etc.) or vice versa,
Adding manganese dioxide powder to hydrogen peroxide 0 An explosive decomposition reaction occurs the moment the two come into contact, and a large amount of water vapor and oxygen generated by the decomposition heat blows up along with the catalyst powder, and the decomposition reaction ends instantly. do. The liquid remaining in the container is in a boiling state.

There are great differences in decomposition ability and rate 1 generation depending on the concentration of hydrogen peroxide, particle size, activation, and purity of manganese dioxide.

〔Example〕

Next, an embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an overall view of the device of the present invention.

In the figure, l is the main body, 2 is a decomposition reaction cylinder that generates oxygen by dropping hydrogen peroxide onto the catalyst contained in it to cause a decomposition reaction, 3 is a hydrogen peroxide supply pump, and 4 is a hydrogen peroxide bottle. , 5 is a rising pipe and cooler for the high temperature oxygen gas and water vapor generated in the decomposition reactor 2, 6 is a cooler consisting of a spiral tube communicating with the rising pipe 5, 7 is a reservoir for collecting condensed water, and 8 is an intake pipe. 9 is a cooling fan for the coolers 5 and 6; 10 is a cock for draining water from the main body 1 and the reservoir 7;

The decomposition reaction column 2 is made of ceramic soy which has a fine porous filtration structure as shown in FIG. Alternatively, a cylindrical shape with a bottom is formed using a hydrogen peroxide-resistant and heat-resistant filter material 11 such as a glass filter, a highly activated powder catalyst 12 is placed in the bottom part, and the lower end of the hydrogen peroxide supply pipe 13 is placed on top of the highly activated powder catalyst 12. The dispersion plate 14 attached to the dispersion plate 14 is positioned, the top thereof is covered with glass wool or other filter material 15 for preventing scattering of the powdered catalyst 12, and the top thereof is further lightly pressed with a porous plate 16. The decomposition reactor cylinder 2 has a capacity several times larger than the capacity of the powder catalyst 12 required to generate a certain amount of oxygen, and can be provided with a large space for temporarily retaining the water vapor and oxygen generated within the cylinder. This is how it was done. Further, a holder 18 through which the hydrogen peroxide supply pipe 13 passes is fitted in the center of the open top of the decomposition reaction cylinder 2 containing the powdered catalyst 12.

The holder 18 includes a central ring 18a through which the hydrogen peroxide supply pipe 13 passes, and an outer peripheral portion 1 that can fit into the top of the 9-decomposition reaction cylinder 2.
8b is connected by a rim 17.

This is for holding the hydrogen peroxide supply pipe 13 and the decomposition reaction tube 2 firmly together.

19 is a filter attached to the lower part of the holder 18.

When hydrogen peroxide is supplied through the hydrogen peroxide supply pipe 13 onto the powder catalyst 12 housed in the decomposition reactor 2 configured as described above, the hydrogen peroxide is dispersed into the catalyst 1 by the dispersion Fi 14.
It is widely dropped onto 2 and comes into contact with the catalyst, causing a decomposition reaction at the same time. A large amount of water vapor and oxygen generated by the heat of the decomposition reaction are transferred to the large 1. ri, overstructure 9 ie.

It spreads in the space surrounded by the filter material 15 and the filter 19, and easily releases a large amount of water vapor and oxygen to the outside of the decomposition reaction cylinder 2 (inside the main body 1), thereby reducing the pressure inside the decomposition reaction cylinder 2.
The water of hydrogen peroxide that did not participate in the decomposition reaction and a part of the hydrogen peroxide undergo a decomposition reaction while descending down the catalyst layer, and the separated water becomes water droplets from the bottom of the decomposition reaction cylinder 2 to the inner bottom of the main body 1. and fall.

The catalyst powder that diffuses upward during the 1-decomposition reaction is captured by the glass wool that also serves as a filter 15 on the catalyst, and the extremely small amount of catalyst powder that has passed through this is captured by the inner surface of the decomposition reaction tube 2 and is removed from the 1-decomposition reaction tube. 2.

As mentioned above, the amount of oxygen generated during the 1 decomposition reaction is 68g (volume: 68g/specific gravity: 1.465 = 4), as shown in the previous equation.
6.4cc) in terms of volume.

22.400cc/46.4cc=483 times the amount.

however.

This is the amount in mercury at 0°C and 760 m.

At a temperature of 90℃ or higher during the decomposition reaction, 36g of decomposition occurred.
Water is generated as water vapor, and the temperature of oxygen is also calculated as 90℃.

16 from just one drop of hydrogen peroxide
Generates 00 times the amount of high temperature water vapor and oxygen. Similarly 35
% For 100g of hydrogen peroxide, 211□0□→211
In the above equation at zO+ O□, only 18.53 g of water was generated due to the decomposition reaction.
．． Assuming that it is generated at 90°C with 531 oxygen, its volume ratio is.

That is, even with 35% hydrogen peroxide, the volume ratio is approximately 400.
It's double.

At the beginning of the research, attempts were made to generate catalyst in a small-volume decomposition reactor using various filter media, but due to the pressure caused by the large volume of generated gas, bubbles of gas accompanied by fine catalyst powder spewed out from the entire surface of the cylinder. Often, they break and the contents spill out and fall into the generator, causing the entire liquid to boil, and the large amount of water vapor generated cannot be cooled down completely by the cooler, resulting in water droplets reaching the inhalation mask. Considering the increase in volume shown in the chemical formula, hydrogen peroxide is placed on top of the catalyst covered with a scattering prevention filter in the decomposition reaction cylinder, which has a large filtration structure surface larger than the volume that can accommodate the catalyst as shown in Figure 3. This figure shows a decomposition reaction column 2 that can be used continuously for a long period of time by dropping the catalyst and leaving it in the decomposition reaction column.

Next, the supply pump 3 and hydrogen peroxide bottle 4 that supply hydrogen peroxide to the decomposition reaction column 2 will be explained.

The supply pump 3 has a circular recess 20 on the inner wall surface as shown in the first figure.
A flexible and elastic silicone tube 21 having hydrogen peroxide resistance is disposed along the inner circumference of the recess 20, and the outer circumference of two discs 23 rotated by a motor 22 is attached to the tube 21. Pressure rollers 24 rotatably attached at equal intervals (3 or more) are inscribed in between, and hydrogen peroxide is sucked into the tube 21 by the pressure of the pressure rollers 24, and is supplied into the decomposition reaction tube 2. The suction side of the pump 3 is in communication with a silicone tube that communicates with a suction needle 27 installed upward in the center of a gripping means 26 that holds and grips the neck 25 of the hydrogen peroxide bottle 4. There is.

Hydrogen peroxide passing through the pump 3 passes only through the tube 27. With this pump 3, hydrogen peroxide does not come in contact with the inside of the pump body like a general pump, so there is no risk of contamination of foreign matter that causes a decomposition reaction in the hydrogen peroxide or damage to the pump due to hydrogen peroxide ( , when the rotation of the pump is interrupted, at least two of the pressure rollers 24 are pressed against the tube 2.
Press 1 to stop the flow. Therefore, unlike general pumps, when the pump stops, the water in the pipes above and below the pump does not flow out due to the difference in head, and the water stops while retaining the hydrogen peroxide in the tube 21. This pump is extremely effective in that it interrupts the generation of gas and enables the generation of gas at the same time as restarting the pump.

As shown in the figure, the hydrogen peroxide bottle 4 has a neck 25 with a slightly long neck, and a cap 28 that seals the mouth of the bottle is made of silicone rubber. There is positive pressure inside the bottle in at least one place outside.
It has a vent hole 30 with a small cut that allows gas to pass through when the pressure is negative, but does not allow liquid to pass through.

This vent hole 30 is used to escape oxygen decomposed by light and temperature during storage.A suction needle 27 is inserted into the cap 28 of the bottle 4, and the suction needle 27 is passed through the cap 28 of the bottle 4, and the hydrogen peroxide inside the bottle is passed through. When the inside of the bottle becomes negative pressure by suctioning it, it serves to introduce air into the bottle 4. In other words, it plays a dual role of smoothing the suction of the pump.

This makes it possible to omit the dangerous work of replacing hydrogen peroxide, which is a deleterious substance, in a tank, which is likely to be contaminated with decomposition function, as in conventional generators using hydrogen peroxide as a generation source. In addition, this bottle 4 serves not only as a container but also as a supply tank to the generator 1, and also allows the piping from the tank to the pump to be maintained to minimize the shortest route. It combines a container and a tank that can save time.

The above-mentioned role of the vent hole 30 is that the manufacturer, before bottling hydrogen peroxide, washes it with detergent, alkaline washing, acid washing, and finally pure water to remove oils and fats that may be decomposed, metal ions, etc.
Even if alkalis, etc. are completely removed and phosphoric acid is added as a stabilizer to make the bottle acidic, it provides an escape port for oxygen gas decomposed due to light and temperature during storage, thereby preventing the bottle from bursting. It is something.

A large amount of high-temperature steam and oxygen generated as described above enters the riser/cooler 5 from the main body 1. This cooler 5 is the second
As is clear from the illustration, a heat sink 31 is provided radially around the outer periphery of the cooler tube 32. The high temperature water vapor and oxygen entering the vertical cooler tube 32 enter the cooler 6 spirally descending at its top. The outside of the coolers 5 and 6 is surrounded by a wind pipe 33, and a cooling fan 9 at the bottom blows air into the wind pipe 33 to cool the coolers 5 and 6 and condense water vapor in the gas, and the water is distributed between the main body l and the spiral cooler. It is made to fall into the reservoir 7 provided below 6. The reason for increasing the capacity of the cooler so much that it seems excessive is to forcefully blow outside air, cool the oxygen that comes out below the outside air temperature, and send the oxygen without water droplets to the mask part from the supply pipe 8. The reason for this is to prevent food poisoning due to incomplete washing with water after bleaching food with hydrogen peroxide.
If the decomposition reactor in the early stage of this generation research ruptures and the entire liquid boils and a large amount of water vapor is generated, if a large amount of oxygen is generated at a rate of 5N/min or more due to the large amount of hydrogen peroxide supplied, the condensed liquid of the generated water vapor may be This is because the experience of detecting the presence of hydrogen peroxide, albeit in a small amount, in the inhalation of hot oxygen leads to confusion about safety and the freshness of inhaling colder oxygen than hot oxygen.

An example of this generator is shown in FIG.

A converter 34 that converts household alternating current into direct current is used to convert the current into direct current. Contacts 36 are provided in which resistances 35 are arranged in order from the largest to the smallest. The contact with the largest resistance 35 has a rate of 11/min, and the contact with the second largest has a rate of 1. 57! The fifth contact with the lowest resistance displays the amount of generation, such as 31/min, so that the user can freely select the desired amount of generation by adjusting the position of the contact 36 and the dial 37. As a result of luck, you can of course change the amount of 1 generation, interrupt 1 generation, or re-occur by turning off the selector switch 38.
, when going to the hospital due to "re-injection" or when the patient's condition suddenly changes,
Alternatively, for use in outdoor sports, etc., the selector switch 38 is switched to the battery side 39.

〔Effect of the invention〕

As explained above, according to the present invention, not only can it be used indoors and outdoors, but also it is possible to generate oxygen instantly and over a long period of time by simply inserting a hydrogen peroxide storage tray into the main body. It has various excellent effects, such as being able to freely select the
