Do-it-yourself oxygen concentrator. DIY hydrogen-oxygen generator

Is it stuffy in the city? I can not breathe? Herald K helps you solve the problem of oxygen starvation.

Oxygen at home. Make it simple and easy.

And super creative too! Connect your kids and loved ones. It's exciting!

And breathe deeply.

Tested on personal experience - mine. It works! Just finished testing!

So. Step one. We go to the pharmacy - any! - and buy there HYDROPERIT in tablets (in St. Petersburg it costs 18 rubles for a pack of 10 tablets) and potassium permanganate in crystals (50 rubles).

step two. We take a glass half-liter jar. Fill it three-quarters full with warm water.

Step Three. We take two tablets of hydroperit. We knead so that they dissolve faster (I wrapped the tablets in a napkin and tapped them a little with a hammer). Try not to get your hands dirty with hydroperite. Not the most useful thing in the world. Pour the powder into a jar and stir. At this stage... nothing happens.

Step Four. We take a teaspoon, pour 5-10 crystals of potassium permanganate into it. Carefully pour these crystals into a jar of diluted hydroperite and stir... it's started!

Well, it's a joke, of course. There will be no fountain. But the water will begin to boil, as if a jacuzzi was turned on inside. This is oxygen! Catch it with your nose!

The chemical reaction releases the purest O2. Do not overdo it. They say that if you actively breathe pure oxygen, then euphoria begins. Although, the devil knows, maybe it's fine?

A couple of sips of oxygen - and let the rest dissolve in the atmosphere of the room. You will become happier and more fun!

And when the seething in the jar ends, the water will turn brown with many floating small sediment crystals inside. Try stirring again - the reaction will continue. And when it ends completely, and all the oxygen comes out ...

Add more hydroperite! And then potassium permanganate!

Yes, it is a very cheap and effective way to get oxygen at home. Make your own oxygen!

Be careful:
1. Do not hold the jar in your hands: heat and hiss are released during the reaction.
2. Don't go overboard with ingredients. Experiment, but don't overdo it.
3. Don't drink this water. It won't do you any good, I guarantee it.

4. The vessel in which you dilute all these components and water should not be metal.

5. Keep matches - and hydroperite - out of the reach of children.

Happy swimming in oxygen!

This homemade oxygen generator may be needed only occasionally: when treating and adapting fish after a long transportation. However, it does not hurt to always have it on hand.

Why would an aquarist need an oxygen generator?

To provide emergency assistance to the fish. Fish can experience life-threatening oxygen deprivation in a number of ways:

You can help such fish if you raise the content of oxygen dissolved in water to a level close to the saturation limit. This can be done by aerating the water with pure oxygen. Oxygen is easy to get from pharmacy 3% hydrogen peroxide, like this:

Photo 1. We need a medicine bottle that closes with two caps: an internal plug and an external one on the thread. Air duct and non-galvanized carnation screws (non-galvanized rust). Shown here is a fairly large vial (100ml) as I was making an oxygen generator for a 250l aquarium. For a small aquarium, you can use a smaller vial (30 ml). The inscription "iodinol" has nothing to do with the case; any cleanly washed vial will do. I just have a lot of these bubbles.
Photo 2. We pierce a small hole in the plug cover, in the screw cover it is necessary to make a hole for the air tube. This can be done with a pointed branch of scissors, wielding it like an awl.
Photo 3. We insert an air tube into the hole of the screw cap, make a muff from chewing gum and ...
Photo 4. ... and seal the hole for the tube.
Photo 5. Pour into a vial fill it no more than two-thirds. We lay the catalyst (screw), close it with both caps and install it in the aquarium. Like this:
Video 1. The air tube must be pushed deeper into the sponge along the water intake tube of the pump. In the vial, the peroxide decomposes into oxygen and water. Oxygen enters the water intake of the pump through a tube and is released into the aquarium together with a jet of water in the form of very small bubbles. At the same time, the water in the aquarium is quickly saturated with oxygen.	Video is not visible, most likely your browser does not support HTML5 video

The amount of oxygen produced depends on the size of the peroxide-catalyst contact surface. Simply put, the more cloves, the more oxygen there will be, but the faster the supply of peroxide will be used up. If we want to saturate the water with oxygen as quickly as possible, then we use a large catalyst, like those screws shown in photo 1. For a long, moderate fall, only a small stump from such a screw is needed.
Security measures: When operating such a generator, one must be sure that the hole in the plug cap is not clogged and oxygen passes freely through it.
From this oxygen generator, a device for long-term metered supply of hydrogen peroxide to an aquarium is easily obtained, which can partly replace the famous one. To do this, remove the air tube, and fix the bubble in the aquarium with the neck down. The oxygen formed in the bubble will squeeze out the peroxide through a small hole in the stopper cap, and the screw cap will insure that the stopper does not accidentally fall out and the entire supply of peroxide does not end up in the aquarium at once. The outlet in the plug cap must be protected from clogging a piece of easily permeable foam rubber. If the peroxide cannot pass through it into the aquarium, then the bubble may explode! That is why hydrogen peroxide stronger than 3% cannot be poured into the vial, and care must be taken when working with this device.

Hey brain inventors! Today's project will create an electric generator from scratch that converts ordinary water into fuel.

Step 1: What is a hydrogen-oxygen generator

An oxy-hydrogen generator, similar to this one, uses electricity from a car battery to split water into hydrogen gas and oxygen. (Electricity + 2H20 -> 2H2 + O2). The result is a fuel that is much more powerful than gasoline, and only water is released as a result of emissions!

It is a completely clean type of fuel, like solar, wind or water energy, electricity is used only to form gas.

The video shows the step-by-step creation of this generator.

NOTE: The amount of electrical energy required to generate the gas is greater than the energy that can eventually be obtained from the generator. This is NOT an energy generator, but a simple energy converter.

Step 2: Preparing metal blanks for generator plates

For this project, we will need stainless steel parts and plastic pipe fittings. You can purchase them at your nearest hardware store.

I used 20 gauge stainless steel (0.8mm) and using a hydraulic puncher punched the required holes in the top and bottom of the plates. As a result, we got 12 plates measuring 7.6 x 15.2 cm, 4 plates 3.8 x 15.2 cm, and 3 connecting strips 2.54 cm, 4 - 1.27 cm and 3 - 0.62 cm. A belt grinder is used to smooth out jagged edges around holes.

Step 3: Increasing the plane of contact between the plates

Next, I used 100 grit sandpaper to sand the plates diagonally. An "X" can be seen on both sides of the plate. This increases the contact area of ​​the plate and promotes the formation of more gas.

Step 4: Configuring Plate Assemblies

The plates are connected in such a way that the 2 inner plates are connected to one electrical terminal and the 2 upper plates are connected to the other terminal. Plastic rods, plastic washers and stainless steel nuts help to make reliable electrical connections.

The alternator plates are assembled in the following order - plate, plastic washers, plate, stainless steel lock nut and so on until all 8 plates are connected.

A step-by-step video instruction for assembling the generator plate is shown.

After assembling the plates, a 10.1 cm plastic plug must be installed, which is attached at the top with several stainless steel screws.

Step 5: Making the Generator Case

The case consists of two 10.1 cm plastic adapters, with an inverted 10.1 cm plug at the bottom. The basis of the case is an acrylic or plastic pipe with a diameter of 10.1 cm. The generator plates and the cover are screwed into the upper part.

The water faucet is made in the same manner from an acrylic pipe with a diameter of 5 cm. It must be attached to the side of the device.

Step 6: Making Faucet Clamps

Clips can be made from the remains of an acrylic or plastic pipe, and subsequently glued with glue to the side of the case.

To make the clamps, I cut 1.9 cm blanks from a 5 cm pipe and cut off the top 0.8 cm to form a grip. Next, I attached the resulting blank to an acrylic rod and attached it to the side of the generator.

Step 7: Installing the Check Valve

A transparent tube and a one-way check valve are installed in the upper elbow. Make sure the valve bleeds the gas and it does not return back into the device.

Step 8: Preparing the electrolyte

To prepare the electrolyte, distilled water and 2-4 tablespoons of KOH (potassium hydroxide) are used. Salt or baking soda are also suitable, but over time they can cause fouling and corrosion of the plates.

I stirred flakes of potassium hydroxide into water, then used a filter to feed the solution into the generator housing (after thorough cleaning).

Note: Potassium hydroxide is caustic and therefore may cause skin burns. Avoid direct contact!

Step 9: Finishing touches

I tested the device using a 12V car battery and jumper cables. The resulting gas is collected in a small water bottle and ignited with a flame.

With a voltage of 12 volts, we get 1.5 liters of gas per minute. If you connect 2 batteries in series, then at a voltage of 24 volts we have 5 liters of gas per minute at the output. That's enough to fill a 4 gallon (15 liter) container in 38 seconds!

Note: At higher voltages, more current is present in the system, resulting in significant heating. In this case, there is a risk that the plastic housing will melt due to high temperatures.

Step 10: How much power is under the hood of our generator?

This system is not intended to be used on a vehicle, but simply demonstrates the process of electrolysis of water and the formation of gas.

Watch the video, which shows experiments on gas ignition, as well as some useful characteristics of the generator.

To get the necessary dose of oxygen, you often have to run to the doctors, knocking out a referral.

Oxygen apparatus for breathing at home: to whom and why it is needed

Such a device is necessary for people suffering from the following ailments:

• bronchial asthma;
• chronic obstructive pulmonary disease (COPD);
• cystic fibrosis;
• heart or respiratory failure;
• pulmonary hypertension.

It is these diseases that prevent the normal saturation of the cells of the human body with oxygen. But even if there are no pulmonary or cardiovascular diseases, an oxygen concentrator for the home can be useful. In the conditions of gas contamination of modern large cities, oxygen starvation begins in a person. It is not clearly felt, but the state of the body can be judged by frequent headaches, chronic fatigue, irritability. In this case, oxygen therapy will not hurt. It will become a source of good mood and a surge of strength. An oxygen plant for the home can help in one more way: it makes delicious and healthy cocktails, but more on that later. First, let's figure out what effect oxygen has on a person.

But such concentrators, in addition to inhalations, can also provide the most useful oxygen cocktails

Oxygen produced by a concentrator: effects on body cells

The oxygen produced by the device helps with recovery after operations, has a tonic effect on the body. It is especially useful for a growing child's body. Doctors say that oxygen cocktails and inhalations are shown to everyone without exception. There is no dispute about the benefits and harms of oxygen concentrators - there is no information about the negative impact.

Oxygen generator for home: device and principle of operation

The device device can be called quite simple. These are two cylinders filled with zeolite balls. The principle of operation of the oxygen concentrator is as follows: the zeolite separates the nitrogen molecules, passing only pure oxygen into the diffuser. The gas mixture produced by the device contains about 95% oxygen, which is more than enough to saturate the cells of the body. In the scheme of such a device, it is necessary to have a compressor that drives air through the cylinders, a dehumidifier, air filters and a humidifier. If desired, you can assemble an oxygen concentrator with your own hands. It is only necessary to find the zeolite with which the cylinders will be filled.

Such devices are powered by batteries or from the mains. The separated nitrogen is thrown back by the device, but its amount is so negligible that it cannot harm others.

Having figured out how an oxygen concentrator works, let's try to consider the various types of such devices and their properties.

Types of oxygen concentrators and their inherent properties

Such devices can be divided into 3 types, each of which has certain properties. Let's list them:

1. Universal or therapeutic oxygen concentrator.
2. Devices for home use.
3. Portable devices.

Let's try to figure out in detail what features each of the types has, how they differ from each other.

Medical (medical) oxygen concentrators: purpose, scope

Medical devices are quite diverse - for first aid in case of emergency, long-term pulmonary therapy. There are also devices for stationary installation. These are mounted in the therapeutic departments of hospitals and produce 5-10 liters of oxygen per minute.

Portable oxygen concentrators: what is it and who uses it

Ambulances are equipped with portable devices to be able to respond in emergency cases. Also, such devices are used by people who are shown daily inhalations, but at the same time a person leads an active lifestyle - goes to the forest, to the lake, to the river. In this case, a portable generator of much-needed gas will be simply indispensable. Even though it produces less than 5 liters of oxygen mixture per minute, in pulsed mode this figure can rise to 6-7 liters.

GOOD TO KNOW!

Pulse - the mode of return of oxygen accumulated in a special reservoir, which is given by the device when inhaling.

Universal device: how does it differ from a medical one

Medium power device (productivity - 5-6 l / min). Suitable for both home and medical use. Used in fitness centers, beauty salons.

Oxygen concentrator for home use: equipment features

The most underpowered of the listed types. Productivity - only 1-3l / min. Suitable for inhalation at home, preparation of oxygen cocktails. They are quite compact, the design is modern and aesthetic, and they are quite convenient to use.

Which oxygen concentrator is better to buy for home use: expert advice

When choosing a similar device and thinking about which oxygen concentrator for home use is better, you should pay attention to its performance and saturation of the gas flow. It must contain at least 70% oxygen. Otherwise, he is worthless.

The next parameter to pay attention to is the size of the device. This is important for its proper placement. There is a rule - the concentrator cannot be placed closer than 30 cm from walls and heaters.

Next, let's look at noise. Low-power devices are practically inaudible during operation, but those with a higher power rating are not so convenient in this regard. In any case, a device with a noise level above 35dB is not worth buying.

Hubs can be very compact - they are easy to transport in a car

Oxygen cocktail at home: what is it for and how to make it

An oxygen cocktail can be consumed daily as a preventive measure. It is very well suited for children who find it difficult to sit still during inhalation. The cocktail has almost the same effect on the cells of the body. If the concentrator has the function of preparing it, the process will not be difficult. Any juice without pulp is poured into a glass up to half, after which the tube of the device is lowered into it. The device turns on, and nothing else needs to be done: after 3-4 minutes, an oxygenated cocktail is ready.

Hub models that are the best according to the editorial site

After reviewing a lot of reviews on the Web, having considered the technical characteristics of many models, the site's editorial team chose several of the best models. This should help our dear reader to make the right choice without unnecessary hassle and many hours of shoveling the Internet in search of a good device.

"ARMED 7F-3L" - an oxygen concentrator with good functionality

"ARMED 7F-3L" is recommended not only for home use, but also for use in a kindergarten, school, fitness center. The productivity of the device is up to 3 l / min at an oxygen concentration of 93%. The dimensions of the device are 480 × 280 × 560 mm, weight - 26.5 kg. Suitable for preparing oxygen cocktails. Here are some of its characteristics.

A little noisy, but overall a pretty decent unit. Here's what netizens are saying about him.

ARMED 7F-3L

"OXYbar Auto" is a product from the very famous brand "Atmung"

Very quiet, light and compact device. The kit includes an adapter for connecting in the car, which is very important for many on long trips. Weight is only 5.2 kg. To date, there are no such light devices on the Russian market. The manufacturer claims that the device can work around the clock. The maximum capacity of the unit is 6 l / min, however, the oxygen concentration will be only 30%, which cannot please. With performance settings of 1l/min, the concentration is acceptable - 90%. Consider the characteristics of the device.

Thus, the device can be called not only the smallest, but also one of the quietest.

Atmung OXYbar Auto

"BITMOS OXY-6000" - a device with fairly good performance

"BITMOS OXY-6000" is the brainchild of German manufacturers. And, like any German technique, it is made very high quality. It has a very convenient shape - it is a "suitcase" on wheels, which is very convenient with a weight of 19.8 kg. The dimensions of the device are 520 × 203 × 535mm. There is a function for preparing oxygen phytococktails. In case of temperature increase, flow rate drop, oxygen concentration drop, network disconnection and microprocessor errors, the device beeps. With a capacity of 1-4l / min, the oxygen concentration reaches 95%. And what about the characteristics?

HELPFUL INFORMATION!

The cost of such devices is quite high and not everyone can afford. That is why today you can find many companies offering an oxygen concentrator for home use for rent at quite reasonable prices.

The most well-known manufacturers of concentrators on the Russian market

The most famous brands on the Russian market are: Bitmos, Armed, Atmung. We could also consider the Russian manufacturer of oxygen concentrators - Mediaflex, but there are no reviews of the owners on large Internet resources about it, which means that we cannot realistically evaluate it. Let's try to consider the other three manufacturers with their best models.

Rules for using an oxygen breathing apparatus at home

The rules for using the device are quite simple. Let's try to consider the algorithm of actions.

1. Pour water into the humidifier (special container). Where it is located - you can easily find out from the technical passport.
2. We attach a special mask or nasal cannula to the device.
3. Turn on the device, put on the mask.
4. We regulate the flow of oxygen, according to the indications of the doctor.
5. We breathe for the required time.

HELPFUL INFORMATION!

If for the prevention of diseases the duration of inhalations of 20-30 minutes a day is sufficient, then in severe forms of COPD, patients should be in an oxygen mask up to 15 hours a day.

Advantages of a concentrator over an oxygen canister for breathing

In fact, the balloon and the concentrator perform the same function - replenishing the lack of oxygen. However, the cartridge has one very big drawback - the limited gas mixture, while the concentrator is capable of performing more fundamental treatment tasks. However, we must pay tribute to the spray can - sometimes, in certain situations, it can help out a lot, and its compactness allows you to take it with you anywhere.

An oxygen tank will not replace a concentrator, but can help out in an emergency

Oxygen concentrator for home use: owner reviews

You might get the impression that all the famous brand name home oxygen concentrator reviews are perfect. Believe it or not, it's up to you.

Oxymed F7-1

The problem lies precisely in the fact that the cost of devices of this type is quite high. This is precisely the reason for such a small number of reviews about oxygen concentrators on the Web.

Finally

Oxygen concentrators are equipment that will be useful to everyone. Of course, not everyone can afford such devices. Let's hope that in the near future the situation with prices will change for the better. In the meantime, you can try to find zeolite on sale and try to make this miracle of technology, which gives youth and health, with your own hands. This will obviously come out cheaper than purchasing a factory-made unit.

We hope that the information was presented in the article clearly and intelligibly. If after reading you still have any questions, the editorial team website will gladly answer them. You are only required to state the essence of the issue in the discussion below. Do you have an oxygen concentrator at home and use it extensively?
