PURPOSE OF THE INVENTION

The purpose is that the disinfection is carried out with hydrogen peroxide gas (H202), in which case corrosion does not occur, because hydrogen peroxide (H202) is not corrosive in its gaseous — state.

The above disadvantages can be eliminated and the above-mentioned goal is achieved with the disinfection method according to the invention, which is characterized by what is defined in the characterizing part of claim 1 and the preferred embodiments of the method are — the object of patent claims 2 to 9. The disinfecting device according to the invention is characterized by what is defined in the distinguishing part of claim 10, and the advantageous embodiments of the fastening element are the subject of independent claims 11 to 14. — As the most important advantages of the invention, it can be mentioned that with the invented disinfection method, a precise dosing of hydrogen peroxide gas is obtained for the object to be cleaned. The exact amount of hydrogen peroxide can be accurately dosed by pouring hydrogen peroxide from one or more nozzles as a liquid stream to one or more heating/heating devices that have one or more evaporation elements, which are evaporation elements.

N 25 — The evaporation element is the upper part of the heating/heating device, on the top surface of which

At the draining end, hydrogen peroxide is drained from one or more draining devices. The evaporator 2 cell consists of fiberglass braid. The evaporation upper surface of the evaporation element is at an evaporation angle of 1 — 30 > degrees when viewed from the side, so that the evaporation drain end is higher a than the evaporation gas end, in which case the hydrogen peroxide flows downhill and spreads evenly throughout

railing, oval, triangle, polygon, etc. On the upper evaporation surface, hydrogen peroxide quickly evaporates into hydrogen peroxide gas as the heating element below the evaporation surface heats the evaporation surface. The air flow above the evaporation surface is faster than the air flow below, so the hydrogen peroxide vaporizes quickly, because the faster air flow above tends to absorb the vaporizing hydrogen peroxide with it. The air flow above the evaporation surface is colder than the air flow below, which results in the formation of airflow vortices above the evaporation element. turbulence, which accelerates the gasification of hydrogen peroxide. It is clear that the use of the invented disinfection method achieves a large cost saving in cleaning.

GENERAL INFORMATION ABOUT HYDROGEN PEROXIDE (Wikipedia) https://fi.wikipedia.org/wiki/Vetyperoxidiff On the topic elsewhere

Hydrogen peroxide (sometimes hydrogen peroxide) H,O2 is the second oxide of hydrogen, whose CAS number is 7722-84-1. Another, more familiar hydrogen oxide is water (HO). Features[edit | edit wiki text]

Hydrogen peroxide is a strong oxidizing agent. When heated, it breaks down into water — — and oxygen, releasing energy in the process. Some metals and impurities act as catalysts for the decomposition process. Hydrogen peroxide liquid can be stabilized with, for example, phosphoric, sulfuric, boric or citric acid, acetanilide or acetophenetidine, when — you want to slow down the decomposition process.

Hydrogen peroxide below 85% does not burn, but it is a strongly oxidizing substance, so hydrogen peroxide together with a combustible substance causes a serious risk of burning or explosion. More than 85% hydrogen peroxide burns with a blue flame when it decomposes, i.e. its decomposition reaction is different from dilute hydrogen peroxide solutions.

S 25 — When decomposed, hydrogen peroxide turns into water and oxygen:

N 2 H,0, > 2 PLO + Os. 2 Hydrogen peroxide is unstable and decomposes by itself, but the reaction is very slow. The reaction > can be accelerated by using a catalyst (e.g. manganese dioxide). Oxygen in hydrogen peroxide

S oxidation number is -I, in decomposition products 0 (O,) and -II (H>O). In the reaction, therefore,

N 30 — tweed proportioning, where the oxidation number both increases and decreases. o The bleaching and disinfecting ability of hydrogen peroxide is based on the highly reactive free oxygen atom formed in the decomposition reaction.

Applications

Hydrogen peroxide has been used, among other things, as an oxidizer for fuel in launch vehicles.

In industry, hydrogen peroxide is used, for example, to bleach pulp and textiles and as a disinfectant in the pharmaceutical and food industries. The hydrogen peroxide used by industry usually contains either 35 or 50 percent hydrogen peroxide, but other strengths are also available. Hydrogen peroxide from 30 to 59 percent can be used in a lower transport class. 100 percent hydrogen peroxide can also be used for disinfection.

In small concentrations (less than 5 percent), hydrogen peroxide is used in cosmetics, among other things — for hair bleaching, and for example as cleaning solutions for contact lenses and for disinfecting wounds. Disinfecting ability is based on the decomposition of hydrogen peroxide with blood acting as a catalyst. The released oxygen kills bacteria PI

Hydrogen peroxide is used quite widely today, because its possible entry into the air or otherwise into nature only causes short-term harm. Once released, it breaks down — quite quickly into water and oxygen, and thus does not cause long-term problems for the environment or the population.
