    BACKGROUND OF THE INVENTION
    At present, it is purified with dilute hydrogen peroxide by spraying. the substance directly into the object (s) to be cleaned.
    The problem is immobility, not migration everywhere. Corrosion effect because hydrogen peroxide is corrosive in liquid form. It is difficult to adjust the amount of hydrogen peroxide 25 because it is impossible to apply hydrogen peroxide evenly to the surface to be cleaned. The concentration of hydrogen peroxide is uneven, resulting in varying purification times. Inaccurate dosing near the humidity point results in condensation of hydrogen peroxide back into a liquid, leaving liquid hydrogen peroxide in the object to be cleaned, which corrodes the object to be cleaned. Today, purification with hydrogen30 peroxide is a slow, inaccurate and therefore expensive job. In addition, part of the object to be cleaned is not cleaned evenly or at all.

    20187128 PRH 09 -09- 2018 hydrogen peroxide is sprayed from the tank with the liquid pressure caused by the pump through the spraying member to the evaporator, to which a hot carrier gas stream is also led. In the evaporator, hydrogen peroxide is converted to hydrogen peroxide gas. A blower is used to blow the carrier gas stream. In JP 2003339820 A, the evaporating member consists of a long, straight open space enclosed in a wall, which is referred to in the publication as a rinsing area / zone into which the rinsing area / zone From the machine translation, “rinsing area / zone with 10 electric heaters downstream of the spray nozzle mounted on the increased diameter rinsing area / zone, the electric heater is long enough, the hydrogen peroxide solution evaporates into fine particles. In addition, the rinsing area / zone has a cylindrical or trumpet-shaped side view and is preferably mounted vertically or horizontally. There is no evaporation surface in the rinsing area / zone.
    From EP2650023 A1 (entire publication; in particular paragraphs 40024); pictures) a disinfection method and a disinfection device for use in cleaning are known. In the method, hydrogen peroxide is atomized from the tank by the liquid pressure caused by the pump through the atomizing member to the evaporating member, to which a hot gas stream is also introduced. In the evaporator, hydrogen peroxide is converted to hydrogen peroxide gas. In particular, it can be seen from Figure 4 that the evaporating member is a closed container with no evaporating surface inside.
    From US2004265459A1 (paragraphs [0006] to [0009j], [0065] to [0068]; The image is known as a disinfection method and disinfection device for use in cleaning. In the method, a disinfectant (e.g., hydrogen peroxide) is sprayed from the tank by the liquid pressure generated by the pump through the spray means into the evaporator, to which a hot carrier gas stream is also introduced. In the evaporator, hydrogen peroxide is evaporated. The publication does not mention that a blower is specifically used to blow the hot carrier gas. In particular, it can be seen from Figure 1 that the evaporator is a closed container with no evaporator surface inside, only baffles for mixing the carrier gas and acetic acid.

    OBJECT OF THE INVENTION
    It is intended that the disinfection be performed with hydrogen peroxide gas (H2O2) so that no corrosion occurs because hydrogen peroxide (H2O2) is not corrosive in the gaseous state.
    The above drawbacks can be eliminated and the above-mentioned object is achieved by the disinfection method according to the invention, which is characterized by what is defined in the characterizing part of claim 1 and preferred embodiments of the method are the subject of claims 2-8. The disinfection device according to the invention is characterized by what is defined in the characterizing part of claim 9, and preferred embodiments of the fastening member are the subject of dependent claims 10-13.
    The main advantages of the invention are that the disinfection method according to the invention provides an accurate dosing of hydrogen peroxide gas to the object to be cleaned. The exact amount of hydrogen20 peroxide can be accurately metered by draining the hydrogen peroxide from one or more nozzles as a liquid stream to one or more heating / heating devices having one or more evaporators, which is an evaporator. The evaporator is the uppermost part of the heating / heating device, on the upper surface of which hydrogen peroxide is drained from one or more drains. The Haih25 duct member consists of a fiberglass braid.

The cross-sectional shape of the blow duct may be other than circular, the cross-section may be of some known shape, e.g. square, rectangular, oval, triangular, polygonal, etc. At the evaporation surface, hydrogen peroxide evaporates rapidly to hydrogen peroxide gas under the heating element below the evaporation surface.
    20187128 PRH 09 -09- 2018 evaporation surface. The air flow above the evaporation surface is faster than the air flow below, whereby hydrogen peroxide gasifies rapidly because the faster air flow above tends to absorb evaporating hydrogen peroxide. The air flow above the evaporation surface is colder than the air flow below, which creates air flow vortices above the evaporator of the support. turbulence that accelerates the gasification of hydrogen peroxide. It is clear that the use of the invented disinfection method achieves great cost savings in cleaning.
    GENERAL INFORMATION ABOUT HYDROGEN PEROXIDE (Wikipedia) https: //f1.wikipedia.0rg/wiki/Hydrogenper0oxide#Theme_other
    Hydrogen peroxide (sometimes hydrogen peroxide) H 2 O 2 is another oxide of hydrogen with CAS number 7722-84-1. Another, more familiar hydrogen oxide is water (H 2 O). Features [edit | edit wiki text]
    Hydrogen peroxide is a strong oxidizing agent. It decomposes into water and oxygen when heated, releasing energy in the process at the same time. Some metals and impurities act as catalysts in the decomposition process. Hydrogen peroxide fluid can be stabilized with, for example, phosphoric, sulfuric, boric or citric acid, acetanilide or acetophenethidine when it is desired to slow down the decomposition process.
    Hydrogen peroxide below 85% does not burn, but is a highly oxidizing substance, as hydrogen peroxide together with a combustible substance poses a serious risk of combustion or explosion. Hydrogen peroxide above 85% burns on decomposition with a blue flame, i.e. its decomposition reaction is different from that of more dilute hydrogen peroxide solutions.
    Upon decomposition, hydrogen peroxide is converted to water and oxygen:
    H 2 O 2 2 H 2 O + O 2 .
    Hydrogen peroxide is unstable and decomposes spontaneously, but the reaction is very slow. The reaction can be accelerated by using a catalyst (e.g. manganese dioxide). In hydrogen peroxide the oxygen oxidation number is -I, in the decomposition products 0 (O 2 ) and -II (H 2 O). Thus, a disproportionation occurs in the reaction, in which the oxidation number both increases and decreases.
    The bleaching and disinfecting ability of hydrogen peroxide is based on the 30 highly reactive free oxygen atoms formed in the decomposition reaction.
    Applications
    Hydrogen peroxide has been used, among other things, as a fuel oxidizer for launch vehicles.
    20187128 PRH 09 -09- 2018
    In industry, hydrogen peroxide is used, among other things, for bleaching pulp and textiles and as a disinfectant in the pharmaceutical and food industries. Hydrogen peroxide used by industry usually contains either 35 or 50 percent hydrogen peroxide, but other strengths are available. Hydrogen peroxide from 30 to 59 percent can be in the lower 5 transport classes. 100% hydrogen peroxide can also be used for disinfection.
    At low concentrations (less than 5%), hydrogen peroxide is used in cosmetics, for example, in hair bleaching, and, for example, as contact lens cleaning solutions and in wound disinfection. The disinfectability is based on the decomposition of hydrogen peroxide when the blood acts as a catalyst. The oxygen released kills bacteria. 121.31
    Hydrogen peroxide is used quite extensively today because its potential release into the air or otherwise into nature causes only short-term harm. Once released, it decomposes fairly quickly into water and oxygen, and thus does not cause long-term problems for the environment or the population.
