Abstract

Electrolysis is a method to cause a chemical reaction, which is widely used in factories or at home. Advancing a chemical reaction via electrolysis is environmentally friendly. A safe application onto a human body is possible, since electrons or electric energy, instead of chemical matters, are used to convert harmful chemicals into less harmful chemicals. Based on the principle, in which the amount of chemicals generated as a result of the electrolysis is proportional to the amount of input electrons, the present invention includes: (1) a step of generating oxygen and hydrogen by electrolyzing water; (2) a step of supplying the oxygen to the indoors, and hydrogen into hydrogen inlets (1-8), so as to cause a chemical reaction with the oxygen, in order to re-utilize electricity, thereby increasing the efficiency of the oxygen generation; (3) a step of detecting the concentration of oxygen using an oxygen sensor, and stopping the water electrolysis device, or decreasing the amount of oxygen generation so as not to increase the concentration of oxygen further, when the concentration of oxygen exceeds a predetermined level.

Description

Automatic Oxygen Generator By Water Electrolysis and Hydrogen Fuel Cell}

Oxygen generator, electrolysis.

Peroxides and superoxides are also used as oxygen generators. They belong to peroxides, such as sodium peroxide (Na2O2) and potassium peroxide (K2O2). Calcium peroxide,

CaO2) and lithium peroxide (Lithium peroxide, Li2O2), and belong to the superoxide is sodium superoxide (sodium superoxide, NaO2) and potassium peroxide (potassium peroxide, KO2). Such an oxygen generating pack is also used in the form of an oxygen generating pack composition containing a component for improving other functions although it is also used in a pure form. Among the various kinds of oxygen generating materials described above, potassium acetate and sodium peroxide have been used as air revitalization materials, which fix the carbon dioxide contained in the air by the reaction shown in the following formulas (1) to (4). This is because oxygen is generated.

Formula 1

Na2O2 + H2O - > 2NAOH + 1 / 2O2

(2)

Na2O2 + CO2 → Na2CO3 + 1 / 2O2

(3)

2KO 2 + H 2 O → 2KOH + 3 / 2O 2

Formula 4

2KO2 + CO2 → K2CO3 + 3 / 2O2

 Of course, air purifiers that remove carbon dioxide contained in the air include soda lime, which is a mixture of calcium hydroxide (Ca (OH) 2) and sodium hydroxide. In addition, lithium hydroxide is widely used, The substance does not generate oxygen, and it removes only carbon dioxide, so air purification efficiency is lower than that of sodium peroxide or potassium oxide. Since powder or pellets can generate a certain amount of dust, it is preferable to install them in a possible container.

The container in which the oxygen generating pack is packed is most commonly a plastic injection molded article. The container is designed to have a nonwoven fabric at the top of the container so that external air can flow into the container. Such a container has a shape similar to a conventional perfume.

Unlike this chemically oxygen-generating method, electrolysis is used for the simple task of charging the battery in daily life, but it is also used in plants to produce chlorine gas (Cl ₂ (g)) or to produce aluminum or copper. It also uses electrolysis to instantaneously produce the necessary oxygen in a confined space such as a submarine or space ship. What is electrolysis, what equipment is needed for electrolysis, and what happens.

Electrolysis refers to any reaction that induces decomposition or conversion of a substance by applying electrical energy to a reaction cell. Electrical energy required for electrolysis is supplied through the electrode. The electrode to be used may be any electrically conductive material. Therefore, not only all metals, but also conductors such as graphite (pencil lead) can be used as electrodes. Electrical energy is supplied from the external power source to the chemicals in contact with the electrodes. As a result, chemicals (molecules or ions) accept electrons through the electrodes, or when they give the electrons to the electrodes, they become oxidized or converted into new chemicals. What is particularly noteworthy is that the chemical reaction in electrolysis is not a homogeneous reaction as a whole, but a heterogeneous reaction that only proceeds around the electrode.

Pure water can not be electrolyzed because electricity does not flow. Therefore, electrolysis of water requires an aqueous solution in which electrolyte is dissolved. For example, an electrolyte solution containing sodium ions (Na ⁺ ) and sulfate ions (SO ₄ ^2- ) is dissolved in water in which sodium sulfate (Na ₂ SO ₄ ) is dissolved. Therefore, when two electrodes are immersed and electric energy is supplied, water abundantly existing around the electrodes is electrolyzed. Likewise, electrolysis of water occurs in a dilute sulfuric acid solution containing concentrated sulfuric acid in water. In this case, sulfuric acid also acts as an 'electrolyte', but also acts as a 'chemical' because the hydrogen ions generated by dissociation of sulfuric acid directly participate in the reaction. Hence, hydrogen gas (H ₂ (g)) and oxygen gas (O ₂ (g)) are generated at each electrode by immersing two carbon (or metal) electrodes in a dilute sulfuric acid solution or an aqueous solution of sodium sulfate.

If the solution is neutral or basic, hydrogen (H ₂ (g)) is generated in the electrode and hydroxide ion (OH ^- ) is generated at the same time. If the solution is acidic, hydrogen ions are reduced and hydrogen is generated. Oxygen (O ₂ (g)) is generated and hydrogen ions are generated at the + electrode. If the electrolysis is continued without shaking the solution, the periphery of the electrode is changed to basic and the periphery of the + electrode is changed to acidic. However, if the solution is well stirred, the hydroxide ion generated by electrolysis reacts with the hydrogen ion to form water, so that the pH of the whole solution does not change. Eventually, electrolysis of water generates hydrogen at the electrode and oxygen at the + electrode. Using this, the oxygen needed in a submarine or spacecraft can be produced on the spot. Hydrogen produced in the process of making oxygen through electrolysis is an additive product.

(- electrode) 2 H ₂ O (1) + 2e → H ₂ (g) + 2 OH ^- ( aq ) (Basic) (- electrode) 2H ⁺ ( aq ) + 2e → H ₂ (g) (+ electrode) 2 H ₂ O (1) - > O ₂ (g) + 4H ⁺ ( aq ) + 4e (acidic)

The present invention has been made to solve the problem of generating a number of adducts when oxygen is chemically generated, the object of the present invention is the electrolysis of water to generate hydrogen at the electrode, oxygen at the + electrode. By using this, there is an advantage that oxygen can be produced on the fly in an enclosed space or a space requiring a high concentration of oxygen. The invention is to invent an oxygen generator equipped with an electrolysis device of high efficiency water that can generate oxygen.

Electrolysis of water to obtain a mixed gas of hydrogen and oxygen by electrolysis of water. The present invention relates to a hydrogen generator and oxygen generators. The water electrolyzer is coupled to the inside, and the end face of the rod-shaped pin is spaced apart from the inner surface and fixed by connecting the insulator rods to the four corners of the positive and negative plates to maintain the space between the space and the pins. It is an invention that is fixed and installed in a water decomposition tank.

Electrolysis is a method of causing chemical reactions that are used throughout the factory or at home. It is environmentally friendly to conduct chemical reactions through electrolysis. It is very safe to apply to the human body in that it uses electrons (electrical energy) instead of chemicals to convert harmful chemicals into useful and less harmful chemicals. The amount of chemical produced as a result of electrolysis and the amount of electricity injected into the vessel are proportional. This is Faraday's Faraday's law of electrolysis. It is possible to synthesize as much purity oxygen as needed from water, and it is more compact than the other oxygen production methods, produces only the required amount of oxygen, Hydrogen can be reused in the hydrogen fuel cell to increase the oxygen generation efficiency.
