Current state of the art

A polluted atmosphere greatly affects public health. It causes the sudden appearance of diseases such as cancer, asthma, allergies or irritations, colds and the viruses of COVID, SARS and MERS. Since people spend up to 70% of their time in closed interiors (in apartments, at work, at school, etc.), their pollution poses a great threat to human health. When a person's immune system encounters these harmful elements, it defends itself and produces an excessive amount of white blood cells, which exhausts the body and puts its health at risk. The cause of an overloaded immune system is most often fatigue, allergies and diseases. Air pollution in closed spaces tends to be large, small and gaseous particles.

Large particles are carried, especially on clothing and shoes or blown through doors or windows, or from the decomposition of building materials, carpets, clothing and sewn materials. They are also a by-product of humans, animals and plants (falling off particles of dead skin, hair, pollen, etc.). They are also found in the internal environment created by human activity, such as vacuuming, cutting, grinding, cooking (flour - baking...) or powdering, etc. Small particles are carried and blown in the form of smoke, pollen, bacteria, viruses, spores, molds and the like. They are also created by smoking, cooking, burning in fireplaces and fireplaces, burning candles, etc.

Gas particles are found in the air in the form of molecules (formaldehyde, odors, benzenes, phthalates...), which are carried by currents during the movement of people, changes in temperature or pressure. They are created by release from materials and human activity.

Commonly known are filter devices that can filter coarse dirt with the help of a filter cloth, but cannot filter out fine and gaseous pollution.

Other commonly known devices are devices that can filter fine and coarse particles using the electrostatic effect, but cannot filter gases, producing ozone harmful to human health, which remains in the space, and is therefore used mostly in industry to filter the air discharge from the premises.

Other known filter devices based on the absorption of activated carbon remove harmful gaseous particles from the air, but cannot or are only insufficiently able to absorb fine particles and viruses.

Devices are also known that use ultraviolet radiation to destroy living fine particles such as viruses and bacteria in the air and on the surfaces of various objects, but have no effect on other large, small and gaseous particles.

Ozonizers are also known, which use high electrical voltage to produce ozone indoors for the purpose of removing viruses, bacteria and spores from the surfaces of objects. However, ozone is dangerous to life at a certain concentration, so after application it is necessary to ventilate the premises for a long time.

There are also various devices described below that combine several of the previously mentioned procedures.

A technical solution according to DE19902825 is known, which concerns a reactor for the decomposition of ozone (O3), consisting of e.g. in photocopiers, ultraviolet sterilizers and similar electrical equipment. The solution is also intended to remove O3 from room air (e.g. swimming pools disinfected with O3), by introducing manganese dioxide (MnO2) and/or lead oxide (PbO2) into air conditioning and ventilation systems, and/or a similar catalyst suitable for the catalytic conversion of O3 to oxygen (O2). The disadvantage of the technical solution is that it does not allow cleaning of mechanical impurities and gases from the air.

According to patent KR200399653, a sterilizer for air purification, or of air flowing through this sterilizer to the outside environment through a photocatalytic filter and an ultraviolet lamp for sterilization purposes, and odor removal. In the absence of ozone, the sterilizer sterilizes and cleans the air, or air e.g. in a motor vehicle, while it can sterilize bacteria stuck to objects with ozone. The sterilizer consists of an ozone generation module with a safety device located on one side of the air outlet; the anion generation module located on its other side and the operation button unit electrically connecting the ozone generation module and the ozone sensor. It contains a large-capacity battery that is portable, such as in a vehicle, and a motor-driven fan. The disadvantage of the mentioned technical solution is its structural complexity and the impossibility of cleaning mechanical impurities and gases from the air.

According to patent US2005207951, a known device for ozone effective deodorization or sterilization of a target space that is contaminated with virus, bacteria, fungi and the like above the reference value, without adversely affecting the human body. This invention includes an ozone generating unit subject to ON/OFF control, a control unit for controlling a number of safety devices that have an effect on the effective control of ozone concentration in a target space, an air filter functional unit that has the function of air purification and removal of residual ozone, and a circulation fan air in the target area. According to this invention, viruses, bacteria and fungi floating in the air can be removed more effectively than a conventional air purifier, even with the removal of odor. The disadvantage of this technical solution is that it does not allow the purification of gases from the air.

Further, according to patent JP2013188447, sterilization in ordinary factories of food or similar products using organic acids is known. During such long-term operation, resistant bacteria or similar substances appear, as well as dust and bacteria in the atmosphere settled on the air filter, circulating air in the room, whereby such bacteria grow and lead to secondary contamination. An air filter for solid dust particles is built into the sterilizer, which also has a sterilizing effect. Dust and bacteria from the atmosphere settle on its air filter. Settled bacteria are further sterilized by the sterilizing effect of the air filter. At the same time, the clean air passed through the air filter is mixed with ozone and sprayed by rotating the discharge hole 360 degrees to sterilize airborne bacteria and adhesive bacteria. The disadvantage of this technical solution is that it does not allow the purification of gases from the air.

The common disadvantage of all mentioned technical solutions is that they do not allow the removal of coarse, fine and gaseous particles and at the same time remove viruses, bacteria and spores from the air and material surfaces without the need for ventilation.

According to CN204153877U, a technical solution for a high-voltage electrostatic plasma air purifier is known, the principle of which consists in the two-sided suction of polluted air by a fan, which after mechanical filtration with a coarse filter is ionized in the equipment, then filtered with a HEPA filter, before a layer of activated carbon, a photocatalyst filter and after treatment with ultraviolet with a germicidal lamp and a non-ionizing device in the form of purified air, it exits through the upper opening into the air. So it is a single-purpose special device for cleaning the air. This device does not contain an electrostatic filter, but only ionization devices, therefore it must additionally contain several filter layers behind them. However, the vertical placement of coarse mechanical filters close to the floor causes these filters to quickly become clogged with coarse dirt that rapidly settles from the bottom up, which reduces the suction of the device and cleans the space horizontally at an increasing height from the floor, therefore it is not even suitable for cleaning objects placed on the floor and cannot be used near the corners of rooms or their walls without a larger distance free on both sides, which is, however, space-consuming. It is necessary to use up to seven double filter segments for air purification according to CN204153877U, which is financially expensive. In addition, such a device does not allow more variants of different economical cleaning solutions.

From the invention JPH1176762A, an air purifier is known, which is formed by a closed box, in the lower part of which a lower fan is mounted behind the suction opening in front of an antibacterial prefilter, above which an ultraviolet lamp, a lower photocatalyst filter, a photocatalyst excitation lamp and an upper photocatalyst filter are mounted in parallel, horizontally. which is located below the ozone generator, formed by the sterilizing ozone generator and the deodorizing ozone generator. Above the ozone generator, a sliding damper with a blocking plate, a motor, an arm, a coupling, a rocking rod, pivoting rods, a support, a plug and a sealing member is installed in the cabinet. The sliding flap is located on the side of the cabinet under the upper fan, photocatalyst, electric dust collector and ozone decomposition catalyst device. The device also includes an ozone sensor and a heater. If there is a human body in the room, sterilization and deodorization is carried out by bringing the air in the room to the air cleaning device from the lower fan, moving the switch flap to the position of the dotted line and decomposing the ozone generated in the ozonizer by the upper fan through the catalytic device, dust collector and ozone depletion catalyst equipment. This sterilized and deodorized air is brought into the room after the remaining ozone in the air is naturally decomposed by strong pressure and strong fan blowing to make it harmless and odorless. On the other hand, in the absence of a human body in the room, the switch flap moves to a continuous line, the ozonizer is activated, and only air containing ozone is brought into the room by the lower fan. After that, the operation of the upper fan is also started, and after the air in the room has been sterilized and deodorized, the switch flap moves to the position of the dotted line. As a result, the air in the room circulates and the ozone is decomposed by the action of the ozone decomposition catalytic device until the air in the room is completely purified. The disadvantage of the technical solution is the content of a large number of air cleaning segments and its overall technical complexity, as well as the fact that it allows the use of only two basic variants of the air cleaning solution.

From the technical solution CN203454285U, a multi-functional air purifier is known using the technology of cleaning polluted air with viruses, bacteria and most toxic and harmful volatile gases using various sedimentation filters with a carbon foam filter and a disinfection and sterilization system, composed of an ultraviolet lamp, a nanotube filter and a filter with activated carbon. In addition, it includes a damping cleaning system, a sound dampening system and a lighting system. The basic function of a virus and bacteria removal system is to kill viruses, bacteria and decompose volatile toxic and harmful gases. Activated carbon filter can absorb and enrich viruses, bacteria and volatile toxic and harmful gases; nano-TiO2 particles on the nanotube filter produce energy band transitions under ultraviolet light excitation, producing photogenerated electrons (e-) and holes (h+). At this time, the dissolved oxygen adsorbed on the nanoparticle surface captures electrons to form superoxide anions, while the holes oxidize hydroxide ions and water adsorbed on the catalyst surface into -OH hydroxyl radicals. Superoxide negative ions and hydroxyl radicals have strong oxidizing properties and can oxidize viruses, bacteria and most toxic and harmful volatile gases to the end products CO2 and H2O. The equipment is complex and expensive, while it does not produce ozone and other secondary pollution during treatment. Moreover, such a device does not allow more different variants of economical cleaning solutions.

It is also advantageous if an additional cabinet is attached to at least one outer side of the cabinet with an installed operating control unit, display member and router.

In addition to the costly use of the entire automatic cleaning, the invention with one air-handling device enables cheaper two stages of a shortened automatic cleaning cycle and with its technical simplicity fulfills the function of a universal device essentially replacing several single-purpose devices with lower costs, which is significantly more financially advantageous for users in terms of procurement and operation of cleaning .

The aim of the invention is to remove large, small and gaseous harmful particles from the air in indoor spaces with one air-conditioning device, and at the same time, at the necessary intervals without the presence of people, to remove viruses, bacteria and spores from surfaces with the help of ozone without the need for ventilation, and at the same time to prevent danger to people and animals from residual gases from ozonation.

Examples of implementation of the invention

In the basic embodiment, the invention is shown in fig. 1 to 6. The ozone sterilizer with air regeneration in the shown basic embodiment is composed of a cabinet 1, a radial fan 3 with suction from the side and an outlet upwards, a suction inlet 4, located in the lower part of the cabinet 1, and an outlet 10, located in the upper part of the cabinet 1 , which are terminated by an unmarked, commonly used wall grid, of a dust filter 5, consisting of e.g. filter fabric G3/G4 according to EN779 installed in the frame, electrostatic filter 6, ultraviolet emitter 7, e.g. formed by some product of the UV-FAN type series, catalytic filter 8, e.g. formed from a catalyst based on MnO2+CuO in the weave of the frame, gas filter 9, e.g. formed by activated carbon in the form of pellets with larger dimensions than the mesh openings of the gas filter 9 mounted in the frame, the switching valve 16 with the servo drive 11, the combined sensor 15 of temperature, humidity, CO2 content and ozone content of the treated air, the display member 13, the operational control unit of the control unit 12 with supply 17 connected to the source of electric current, preferably e.g. to a regular electrical network with an alternating voltage of 230 V/50 Hz and a remote management router 14. The fan 3, electrically connected according to fig. 9 with the operational control unit 12 and the display member 13 fixed from the side on the wall of the cabinet 1, while under the intake of the fan 3, a dust filter 5, an electrostatic filter 6 and an ultraviolet emitter 7 are located in the lower part of the cabinet 1 behind at least one of the intake inlets 4. Above the fan 3 is located in its printing part, e.g. obliquely downwards at an acute angle of 15 to 85 angular degrees, a catalytic filter 8 in front of the discharge outlet 10 located in the upper part of the cabinet 1, a sensor 15 of temperature, humidity, CO2 content and ozone content in the conditioned air and at least one gas filter 9, while in front of the catalytic filter 8, the switching valve 16 with servo drive 11 is installed. According to fig. 9 is a sensor 15 of temperature, humidity, CO2 content and ozone content in the treated air via the operational control unit 12 electrically separately connected to the fan 3, the electrostatic filter 6, the ultraviolet emitter 7 and the servo drive 11.

According to fig. 7 and fig. 8, the ozone sterilizer with air regeneration is activated by a command from the operational control unit 12 after connecting it to the source of electric current and mechanically setting its operation by the operator, either to its automatic full or one of the two shortened cycles of air cleaning, which are controlled by control signals from the combined sensor 15, i.e. i., if it detects that there is some data in the external environment of the ozone sterilizer with air regeneration, e.g. temperature, humidity, CO2 content and ozone content, outside the set reference safe concentration.

In the case of a connection in the operational control unit 12 for the entire automatic cleaning cycle, according to fig. 2 and fig. 5 to fig. 8, the operational control unit 12 simultaneously activates the fan 3, the electrostatic filter 6, the ultraviolet emitter 7 and the servo drive 11 by means of an electric command (current), which swings the switching flap 16 away from the catalytic filter 8 - see fig. 5 and fig. 6. The air is cleaned by suction with a fan 3 through the air intake inlet 4 and a dust filter 5, which captures large particles of pollution from the cleaned air. Then the air is cleaned by an electrostatic filter 6, where small particles are negatively charged by a high electric voltage and attached to its grounded tubular frame, which is preferably made of stainless steel. The purified air then passes through the ultraviolet emitter 7, where the next level of elimination of viruses, bacteria and spores occurs. The air freed from large and small particles, including viruses, bacteria and spores, is further pushed by the fan 3 through the catalytic filter 8, which modifies ozone into oxygen, and the gas filter 9 with activated carbon, which removes gaseous harmful substances contained in the air, and the mechanically adjustable directional exhaust air outlet 10 back to the outside space. During the entire filtration cycle, the temperature, humidity, CO2 content and ozone content in the air are sensed by the sensor 15. The measured values are simultaneously displayed by the display member 13 and evaluated with their set reference value by the control program in the form of a recommendation for the operator.

In the case of connection in the control unit 12 to the 1st stage of the shortened automatic cleaning cycle according to fig. 3, fig. 4, fig. 7 and fig. 8, intended for the need for only ozonation of air and/or the surfaces of things, the fan 3, the electrostatic filter 6, the ultraviolet emitter 7 and the servo drive 11, which folds the switching flap 16 towards to the catalytic filter 8 - see fig. 3 and fig. 4. Servo drive 11 changes the air path in the ozone sterilizer with air regeneration. Intake air containing oxygen continues through the mechanically adjustable directional supply air inlets 4 and dust filter 5, where large particles are captured, to the electrostatic filter 6, where the so-called corona discharges are created due to the action of high electric voltage, which decompose oxygen into ozone. Further, the purified air in the ozone sterilizer with air regeneration passes through the ultraviolet emitter 7, where the next level of elimination of viruses, bacteria and spores occurs. The air freed from large and small particles, including viruses, bacteria and spores, is subsequently led out through the mechanically adjustable directional air outlet 10 back to the outside space. Temperature, humidity, CO2 content and ozone content are measured during the entire cycle of oxygen to ozone conversion. The values are displayed by the display member 13, evaluated with the set reference value by the control program in the operational control unit 12, and based on them, the air cleaning cycle in the ozone sterilizer with air regeneration continues only after reaching the set reference concentration required for ozonization of surfaces in closed spaces. In order to avoid endangering people and animals by ozone poisoning, this cleaning phase is done without their presence. Then, in the ozone sterilizer with air regeneration, the air duct is automatically switched by the servo drive 11, by tilting the switching flap 16 away from the catalytic filter 8, and the previously described automatic cleaning cycle according to fig. 3 and fig. 6 to fig. 9. Subsequently, after reducing the ozone concentration in the space to the set reference level, which does not endanger people and animals, the ozone sterilizer with air regeneration in the control unit 12 turns off.

In the case of connection in the control unit 12 to the 2nd stage of the shortened automatic cleaning cycle according to fig. 3, fig. 4, fig. 7 and fig. 8, if the use of an electrostatic filter 6 is not required in the case of the need for rapid air purification with a small elimination of viruses, bacteria and spores, where the so-called corona discharges, which decompose oxygen into ozone, and an ultraviolet emitter 7, where the next stage occurs, are created by the action of high electric voltage elimination of viruses, bacteria and spores, the fan 3 and the servo drive 11 are simultaneously activated by means of the operational control unit 12 with an electrical command (current), which folds the switching flap 16 towards the catalytic filter 8 - see fig. 3 and fig. 4. Servo drive 11 changes the air path in the ozone sterilizer with air regeneration. The oxygen-containing air taken in through the mechanically adjustable directional supply air inlets 4 continues through the dust filter 5, where large particles are captured, and the mechanically adjustable directional exhaust air outlet 10 back to the outside space. Temperature, humidity, CO2 content and ozone content are measured during the entire cycle of oxygen to ozone conversion. The values are displayed by the display member 13, evaluated with the set reference value by the control program in the control unit 12, and based on them, the air cleaning cycle in the ozone sterilizer with air regeneration continues only after reaching the set reference concentration necessary for ozonization of surfaces in closed spaces. In order to subsequently prevent danger to people and animals from ozone poisoning, in the ozone sterilizer with air regeneration, the air-handling path is automatically switched by the servo drive 11 by tilting the switching flap 16 away from the catalytic filter 8, and the previously described automatic cleaning cycle occurs according to fig. 2 and fig. 5 to fig. 8. After reducing the ozone concentration in the space to a level that does not endanger people and animals, the ozone sterilizer with air regeneration in the operational control unit 12 is turned off.

Further embodiments of the subject of the invention are shown in fig. 9, where an ozone sterilizer with air regeneration is shown, whose cabinet 1 has rotating wheels 2 attached from below and is made of two parts that are mutually air-tight and coaxially connected at the front with attached two additional cabinets 18. The internal structure and working operation of this ozone sterilizer with air regeneration is identical to its already described basic design. In this embodiment of the invention, the suction inlet 4 is mounted horizontally at the bottom and vertically at the side. At the same time, the gas filter 9 is horizontally from the top and vertically from the side behind the discharge outlets 10. The second lower additional box 18 is mainly used for fitting the various safety devices of the ozone sterilizer with air regeneration according to the invention, which are not specified in the description.

The described and illustrated embodiments are not the only possible embodiments of the present invention, because the number of suction points may be different from those illustrated, the box 1 may be equipped with a different number of rotating wheels 2, not shown, the dust filter 5 may be equipped with several suction inlets 4 and may be formed with them in the form of a block. Also, the catalytic filter 8 does not have to be placed diagonally above the fan 3 in its discharge part. The operational control unit 12 can be remotely connected to the display member 13 and the router 14. Alternatively, the operational control unit 12 can be installed outside the cabinet 1 in some additional cabinet 18. The fan 3 can be of a different construction and its discharge part and the switching flap 16 can have a different shape and placement position as shown. Also, the shape, the central exhaust pipe from the production machines can be led through the ozone sterilizer with air regeneration directly into the atmosphere, etc.

Industrial applicability

The ozone sterilizer with air regeneration according to the invention can be used in many ways in various closed spaces, which are intended for cleaning the air from harmful substances, odors, viruses, bacteria and the like, e.g. in military facilities and means of transport, in hospitals, waiting rooms, conference and production halls, offices, schools, in personal transport vehicles, e.g. in planes, ships, long-distance and urban means of mass transportation of people, etc. Also, the invention can be applied to cleaning the surfaces of objects with ozone followed by the removal of harmful substances on their surface after cleaning without the presence and intervention of persons and operators.
