JP 2003339829 A (figure; machine translation paragraphs [001 3] to [0024]) discloses a disinfection method and a disinfection device for use in cleaning. In the method, hydrogen peroxide is atomized from the tank by the liquid pressure caused by the pump through the atomizing member to the evaporator, to which a hot carrier gas stream is also introduced. In the evaporator, hydrogen peroxide is converted to hydrogen peroxide gas. A blower is used to blow the carrier gas stream. In JP 2003339829 A, the evaporating member consists of a long straight open space with a closed wall, which is referred to in the publication as a rinsing area / zone into which the rinsing area / zone is warmed with air and hydrogen peroxide solution is sprayed together. From the machine translation, “rinsing area / zone with downstream side of the spray nozzle has - an electric heater mounted on an increased diameter rinsing area / zone, the electric heater is long enough, the hydrogen peroxide solution evaporates into fine particles. In addition, the flushing 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 EP2650023A1 (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 sprayed from the tank with the liquid pressure caused by the pump through the atomizing member to the evaporator, 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 evaporator is a closed container with no evaporation surface inside. From US2004265459A1 (paragraphs [0006] to [0009j, [0011], [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 with the liquid pressure generated by the pump through the spray means into the evaporator, to which = a hot carrier gas stream is also led. In the evaporator, hydrogen peroxide is evaporated. Publication 7 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 evaporating member is a closed container in which there is no evaporating surface A 30 only guide plates for mixing the carrier gas and acetic acid.

N In all publications JP 2003339829 A, EP2650023A1 and US2004265459A1, the evaporating member consists of a closed tank-like structure with no evaporating surface or means inside the tank-like structure. In all publications JP 2003339829 A, EP2650023A1 and US2004265459A1, hydrogen peroxide is sprayed with a liquid pressure generated by a pump into an evaporator in which hydrogen peroxide is evaporated.

—IN OBJECT OF THE INVENTION It is intended that the disinfection be performed with hydrogen peroxide gas (H 2 O 2) so that no corrosion occurs because hydrogen peroxide (H 2 O 2) 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 to 9. The disinfection device according to the invention is characterized by what is defined in the characterizing part of claim 10, and preferred embodiments of the fastening member are the subject of dependent claims 11 to 14.

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 hydrogen peroxide can be accurately metered by draining hydrogen peroxide from one or more nozzles as a liquid stream to one or more heating / heating devices having one or more evaporating means, which is an evaporating means. 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 drainage devices to the drain end. The evaporating member consists of a fiberglass braid. The evaporating top surface of the evaporator 4 is at an angle of 1 to 30 ° A when viewed from the side so that the evaporating drain head is higher than the evaporating gas head, the hydrogen peroxide flows downhill - the installation is best performed in a controlled manner by one or more blow ducts / blow pipes. The cross-sectional shape of the blow duct may be other than N circular, the cross-section may be of a known shape, e.g. square rectangle, oval, triangle, polygon, etc. At the evaporation surface, hydrogen peroxide rapidly evaporates into hydrogen peroxide gas below the heating surface below the evaporation surface.

The airflow above the evaporation surface is faster than the airflow below, whereby hydrogen peroxide gasifies rapidly because the faster airflow above tends to absorb evaporating hydrogen peroxide.

The air flow above the evaporation surface is colder than the air flow below, which results in 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://en.wikipedia.org/wiki/Hydrogen peroxide Elsewhere on the topic Hydrogen peroxide (sometimes hydrogen peroxide) H2O2 is another oxide of hydrogen with CAS number 7722-84-1. Another, more familiar hydrogen oxide is water (HO). Features [edit | edit peroxide] Hydrogen peroxide is a highly oxidizing agent.

It decomposes on heating into water ... and oxygen, releasing energy in the process.

Some metals and impurities act as catalysts in the decomposition process.

Hydrogen peroxide liquid can be stabilized with, for example, phosphoric, sulfuric, boric or citric acid, acetanilide or acetophenidine when it is desired to slow down the decomposition process.

Hydrogen peroxide below 85% does not burn, but it is a highly oxidizing agent, so 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.

On decomposition, hydrogen peroxide is converted to water and oxygen: 2 HO; > 2 HO + O). = 25 - Hydrogen peroxide is unstable and decomposes spontaneously, but the reaction is very slow.

Reaction 3 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>) and -II (HO). Thus, in the reaction, a 7-proportionalization occurs in which the oxidation number both increases and decreases.

S The bleaching and disinfecting capacity of hydrogen peroxide is based on the A 30 - highly reactive free oxygen atom formed in the decomposition reaction. = N Applications Hydrogen peroxide has been used, among other things, as a fuel oxidizer for launch vehicles.

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% hydrogen peroxide, but other strengths are available. Hydrogen peroxide from 30 to 59% can be in the lower transport category. 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 disinfecting ability is based on the decomposition of hydrogen peroxide when the blood acts - as a catalyst. The oxygen released kills bacteria PI Hydrogen peroxide is used quite widely today because its possible 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.
