Definitions
- the claimed invention relates to microbiology and can be used in installations for the disinfection of clothes, shoes, wearable items on people, human skin and hair, by using the "Heavenly Shield” technology, which consists in supplying an air-ozone mixture to the disinfection object in combination with scattered ultraviolet radiation.
- the claimed method of disinfection can be implemented in hygienic equipment for servicing passenger facilities of railway, air and water transport, subway, hotels and medical, educational, sports and other institutions of various profiles.
- the invention can be used for disinfection, sterilization, premises, as well as sanitization of various equipment - containers, inventory, raw materials, finished products and overalls for personnel, including medical institutions.
- the device contains a microwave path, one section of which is equipped with a microwave energy emitter in the form of a microwave-transparent slot and a source of ultraviolet (UV) optical radiation, placed coaxially with the path and made in the form of an axisymmetric electrodeless microwave gas-discharge lamp, in microwave and UV transparent vacuum-tight shell of which a through vacuum cavity is formed along the axis of symmetry.
- a microwave energy emitter in the form of a microwave-transparent slot and a source of ultraviolet (UV) optical radiation
- a device for air disinfection in buildings in which a method for air disinfection is implemented (patent No. 2 475 270, RU, 02.06.2006) using a plurality of photocatalytic reactors installed in ventilation ducts and containing at least one to the first and second outputs of the high-voltage pulse shaper.
- a method is known in which excited atomic and molecular oxygen is used to sterilize an object, obtained from a mixture of air with ozone by irradiating it with light quanta with a wavelength of 1 OO-3OBO A and an energy hv> 5.26 eV.
- the listed methods are distinguished by the technical complexity of their implementation, their labor-intensive applicability to the disinfection of clothes, shoes, wearable things in public, human skin and hair, and the duration of disinfection.
- the aim of the invention is to eliminate the above disadvantages by using the "Heavenly Shield” technology, in which a mixture consisting of air and ozone in combination with scattered ultraviolet radiation is used as a disinfectant.
- the technical result of the claimed invention is to improve the reliability and quality of surface disinfection, including the ability to process clothing, shoes, wearable items, human skin and hair, and reduce the time for disinfection.
- the disinfection of objects occurs as follows.
- the disinfection object is blown from all sides with a mixture of air and ozone with a low ozone content, and at the same time the bactericidal emitter generates ultraviolet radiation, which is scattered through special deflectors.
- the disinfection time is 30-40 seconds, which allows for a high throughput of the disinfection unit and does not cause any harm to human health.
- the disinfection time is 30-40 seconds, which allows for a high throughput of the disinfection unit and does not cause any harm to human health.
- the amount of ozone in the mixture during the treatment of objects is required to be insignificant (10-25 times less than during long-term treatment of objects and the atmosphere with a simple ozone-air mixture, i.e. with a capacity of not more than 10 mg/m3, but not exceeding the MPC value of 0.16 mg/m3, instead of 15-25 mg/m 3).
- Ozone The direct cause of bacterial death under the action of ozone is local damage to the plasma membrane, leading to the loss of bacterial cell viability and/or its ability to reproduce.
- Ozone molecules interact not only with the components of the surface membrane, but, by changing its permeability, lead to the destruction of intracellular organelles in 10-20 minutes.
- ozone is able to kill all known types of gram-positive and gram-negative bacteria, including Pseudomonas aeruginosa and Legionella, all lipo- and hydrophilic viruses, including hepatitis A, B, C viruses, spores and vegetative forms, all known pathogenic fungi and protozoa.
- the disinfection method must be implemented in a closed space with a supply and exhaust ventilation system equipped with fans to control the movement of gases in the device.
- a variant of the device for disinfecting objects, in which the proposed method of disinfection can be implemented, is shown in Fig. 1.
- the unit consists of a housing 1 equipped with a supply ventilation system, including a ventilation duct 2 with deflectors 3, fans 4, filters 5.
- the supply ventilation system also includes a ventilation duct 6 with deflectors 7 for supplying an air-ozone mixture.
- the device is equipped with an ozone generator 10 with an air-ozone mixture creation fan 11 and distribution fans 12.
- the exhaust ventilation system consists of a duct 13 with ventilation grilles 14. Exhaust gases are emitted through the exhaust pipes 15, it is possible to connect to the exhaust ventilation of the building, if the device is placed internally.
- a bactericidal irradiator 16 is placed in the ceiling of the building 1.
- the bactericidal irradiator is placed in a ceiling 17 with deflectors 18.
- the device operates as follows. An object of disinfection is placed inside the housing 1 or a person enters. Next, the disinfection process begins. Air is supplied through the ventilation duct 2 through deflectors 3, which passes through filters 5 for cleaning, and is blown by fans 4. Air is supplied mainly to the upper part of the chamber.
- the ozone generator 10 produces ozone, which is mixed with the air passing through the filters 5 by means of a fan 11, forming an air-ozone mixture. With the help of fans 12, this mixture is directed through the ventilation duct 6 and through deflectors 7 is sent to the object of disinfection, including the body, clothes and shoes of a person inside the device.
- the bactericidal irradiator 16 generates ultraviolet radiation, which is scattered through the deflectors 18 of the ceiling 17. Simultaneously with the supply of gases, the system also functions exhaust ventilation, where the gas from the chamber is discharged through the duct 13 through the grates 14 and exhaust pipes 15.
- the released gas mixture contains ozone, which is an unstable gas, and within 10 to 20 minutes returns to its natural state Og, and thus thus does not harm the environment.
- the object of disinfection can be removed from the chamber.
- the uniform distribution of the ozone-air mixture with ultraviolet irradiation provides a uniform coating of clothes, shoes, wearable things of a person, his skin and hair, and, therefore, guarantees fast and high quality disinfection.
- the method at least up to 80% of all viruses, microbes carried on clothes and shoes are destroyed. It is environmentally friendly.

Abstract
L'invention peut être utilisée dans des installations de désinfection de vêtements, de chaussures, d'affaires portables par des personnes, de manteaux en cuir ou en pelage d'une personne, ceci en utilisant en utilisant la technologie "Bouclier céleste", qui consiste à envoyer vers un objet à désinfecter un mélange d'air et d'ozone en combinaison avec la diffusion d'un rayonnement ultraviolet. L'objet à décontaminer est soufflé de tous les côtés avec un mélange d'air et d'ozone avec une faible teneur en ozone, et un émetteur bactéricide génère simultanément un rayonnement ultraviolet qui est diffusé à travers des déflecteurs spéciaux. Le temps de désinfection est de 30-40 secondes, ce qui permet d'assurer une grande vitesse de passage de l'installation de désinfection et d'exclure tout danger pour la santé humaine. Ce procédé de désinfection peut être mis en oeuvre dans des techniques d'hygiène afin de desservir des lieux de passagers de transport ferroviaire, aérien ou maritime, le métro, les hôtels et les établissements de soins et de prévention, d'enseignement, sportifs et autres ayant des profils divers. L'invention a pour but d'augmenter la qualité et la fiabilité de désinfection des surfaces à traiter.
