Description

Technology area

This invention relates to a disinfection system and, in particular, to a system and equipment for the disinfection of various media using ozone.

State of the art

As a result of global growth and expansion of cities and towns, society generates significant volumes of domestic and industrial wastewater.

The problems of pumping stations for the disinfection of wastewater and wastewater treatment plants (for industrial and private use) and the neutralization of unpleasant odors are of increasing concern. Residents complain of deteriorating health, persistent headaches, nausea, an increase in cases of depression and sudden mood swings. This is quite understandable and is supported by scientific research [Associate Professor Dr. Dainius Paliulis and Dr. Egle Zuokaite, Guidelines for deodorization]. Sewage pumping stations and industrial and domestic wastewater, as well as their contents in wastewater treatment plants, become a medium for the growth of microorganisms (especially at high temperatures), which leads to the creation of additional pollutants such as bacteria, protozoa, molds, etc. which in turn produce other organic pollutants. Fungi, bacteria and gases not only accumulate in sewage pumping stations and wastewater treatment plants, but are also transmitted through the air, especially within areas where residential buildings are located near sewage pumping stations. Therefore, there is a significant risk to human and animal health. When disinfection is carried out using water and chemicals, the disinfectant mixture does not always sink into all crevices and gaps in the wastewater collection and treatment system, which may contain sources of odor and contamination.

Another source of odor and pollution is municipal waste storage facilities in residential buildings, where significant amounts of waste accumulate. Such waste in repositories typically includes non-food, inorganic, food and other organic waste. Some of these wastes and their contents rot, become a breeding ground for pests, and also contain unwanted contaminants such as bacteria, protozoa, fungi, molds and other organic pollutants. In addition, fungi and bacteria not only accumulate in storage but can also be transmitted through the air. Therefore, waste storage poses a health risk, poorly controlled waste storage can lead to the transmission of infection by pests and the onset of the spread of unpleasant odors. Likewise, the aforementioned problems often occur in buildings that have chutes installed to discharge waste from other floors of the building into a waste storage facility.

A similar problem occurs in rooms and equipment, where certain conditions can give rise to fungi and / or bacteria that can pose a risk to human health by spreading in the atmosphere, or at least cause unwanted / unpleasant odors. Such rooms and equipment may include ventilation air ducts, for example:

1) premises for storing food and non-food products;

2) rooms for used collection containers, equipped with vending machines that recycle packaging;

3) refrigerators (for industrial use and for individual use);

4) refrigerators for storing food in seaports and airports;

5) premises for storing products, raw materials and finished products of the food industry (meat, fish, milk, etc.);

6) premises of healthcare institutions requiring disinfection;

7) rooms and other premises of hotels (especially after smoking clients stay in them);

8) smoking rooms;

9) public catering facilities;

10) sanitary facilities for public and private use;

11) premises and equipment (for industrial use and for individual use) for collecting or pumping out household and industrial wastewater, ventilation systems and stations for limiting the spread of recycling wastewater;

12) ventilation systems for residential, industrial buildings and buildings for other purposes;

13) public transport and transport for freight traffic;

14) commercial buildings with adjacent buildings and plots;

15) changing rooms in gymnasiums and swimming pools.

Disinfection systems are available in automated sewage pumping stations and wastewater treatment plants (industrial and municipal) that neutralize and destroy molds, bacteria and other harmful microorganisms, as well as biogas found on surfaces or in the air. One such system is disclosed in the patent specification no. LT5977B (patent no. 5977, publication date 12/27/2013), also disclosed in patent application no. 017228 (application no. 2016110902, Russian Federation, publication date 03/24/2016), which especially focuses on the prevention of bad odor from sewage to residential buildings. Based

- 1,036680 patent applications No. LT5977B (patent No. 5977, publication date 12/27/2013), No. 017228 (application No. 2016110902, Russian Federation, publication date 03/24/2016) the approach to solving the problem is carried out only superficially, i.e. they deal with the effects of unpleasant odors rather than their causes. On the basis of application No. 017228, the approach to the problem of a sewage pumping station is carried out by installing a methane sensor, and when an increase in the concentration of methane is detected, an ozone generator in the sewage pumping station is activated. Ozone is an effective disinfection gas and can effectively disinfect a large volume of air to prevent the accumulation of biofilms, bacteria, fungi and biogas in the sewage pumping station. The use of an ozone generator in a sewage pumping station is an effective means of neutralizing unpleasant odors and reducing the incidence rate of diseases such as allergies, rashes, viral infection of the upper respiratory tract, legionellosis. It is also known that ozone prevents the spread of fungi and parasites and destroys most of the biogas. Therefore, the system described in applications nos. LT5977B and 017228 can significantly improve sanitation.

Despite this, the typical wastewater odor control system described in Application No. LT5977B has its drawbacks. First, it generates ozone only when an increase in methane concentration is detected in the sewage pumping station. With such a system, the problem of other contaminants in the sewage pumping station is not directly addressed. For example, there may be periods when the processes of decomposition and enzymatic decomposition of wastewater take longer due to low temperatures of the atmosphere. In such cases, the relative amount of methane decreases, so the system becomes less effective in solving the problems of residual biofilms, fungi and other pests, as well as biogas. In addition, while the system is an effective means of preventing the spread of unpleasant odors from wastewater, the ozone itself may smell, which is quite pungent and toxic. Ozone is also a hazardous substance, and its high concentration in a sewage pumping station can be unpleasant for people nearby. Exposure to high concentrations of ozone can also cause headaches, respiratory and eye irritation, and even longer-term adverse effects, including lung damage. In the description of the system, there are no proposals for modifications to regulate the amount of ozone produced, on the use of ozone sensors to monitor the ozone level in a sewage pumping station and an ozone generator when the ozone concentration exceeds a predetermined threshold. Although such a simplified safety deactivation mechanism can prevent the occurrence of a hazardous ozone level, other factors have not been taken into account in identifying an acceptable ozone concentration level.

There are automatic decontamination systems for waste container storages that neutralize and destroy mold, bacteria and other harmful microorganisms, as well as biogas found on surfaces or in the air. One such system is described in patent application US 14/532867 (US publication number 2015/0157753), which focuses on preventing unpleasant waste odors from entering residential floors through chute openings on each floor of the house. Based on patent application US 14/532867, the upper part of the garbage chute is equipped with a methane sensor, and when the methane concentration rises, an ozone generator in the waste storage is turned on. Ozone is an effective decontamination gas and can effectively decontaminate large volumes of air to prevent the accumulation of biofilms, bacteria, fungi and biogas in waste storage and associated refuse chutes. The use of an ozone generator in a waste storage is an effective means of neutralizing unpleasant odors and reducing the incidence rate of diseases such as allergies, rashes, viral infection of the upper respiratory tract, other viral diseases, legionellosis. It is also known that ozone prevents the spread of fungi and parasites. Therefore, the system described in applications nos. LT5977B and 017228 can significantly improve sanitation.

The typical wastewater odor control system described in US 14/532867 has its drawbacks. First, the system based on patent application US 14/532867 generates ozone only when an increase in methane concentration is detected at the top of the chute. The system based on patent application US 14/532867 is suitable for waste collection only in systems with waste chutes. When the system is used in accordance with patent application US 14/532867, the problem of other contaminants present in the same system may not be directly addressed. For example, there may be periods when the processes of decomposition and enzymatic decomposition of wastewater take longer due to low temperatures of the atmosphere. In such cases, the amount of methane released is correspondingly reduced, so the system according to patent application US 14/532867 becomes less effective in solving the problems of residual biofilms, fungi and other pests present in the waste storage.

While the system described in US Patent Application No. 14/532867 is an effective means of preventing the spread of unpleasant odors from chute openings, an ozone odor can be generated that is quite pungent in itself. Ozone is also a hazardous substance and

- 2 036680 high concentration in a repository can be unpleasant for people living nearby, or for those who often visit the repository, for example to empty waste containers. Exposure to high concentrations of ozone can also cause headaches, respiratory and eye irritation, and even longer-term adverse effects, including lung damage. To control the amount of generated ozone, modifications have been proposed in accordance with patent application US 14/532867, proposing the use of ozone sensors to monitor ozone levels in garbage chutes and storages and turning off ozone generators when the concentration exceeds a predetermined threshold. Although such a simplified safety deactivation mechanism can prevent the occurrence of a hazardous ozone level, other factors have not been taken into account in identifying an acceptable ozone concentration level.

European patent application 12795746.2 discloses a method for decontaminating one or more surfaces and / or sterilizing air and a device for use in said method. The method includes a safety process for isolating surfaces to be disinfected, the disinfection operation includes emission of UV radiation to generate ozone and / or sterilize air from one or more UV sources, adding generated ozone to the specified zone of said isolation, and also the operation of interrupting the process to stop generating ozone and stopping the safety process. The method and apparatus have insufficient safety and insufficient stability.

US patent application 10/783665 discloses a bio-air sterilization system for removing harmful contaminants and particles such as bacteria, viruses and fungi from the air of an enclosed area, as well as from surfaces within the enclosed area, while maintaining a safe workplace for people. The bio-air sterilization system uses a compressor to circulate room air through a pre-ionized space and contains a dual UV irradiation system within the bio-air sterilization system. This system also lacks security and stability.

The aim of the invention is to solve the problems arising from the use of typical disinfection systems aimed at disinfecting various environments using ozone.

Other features and advantages of the invention are set forth in the description with reference to the drawings.

FIG. 1 depicts a system for the disinfection of wastewater pumping stations using ozone based on the first modification of the present invention.

FIG. 2 shows a system for the disinfection of wastewater treatment plants (open systems for collecting and treating wastewater) using ozone based on the second modification of the present invention.

FIG. 3 shows a system for decontamination of premises using ozone based on the third modification of the present invention.

FIG. 4 depicts a system for decontaminating premises using ozone based on the fourth modification of the present invention.

Turning to a detailed description of examples of implementation of the invention, we draw attention to the fact that identical elements are designated in the drawings by the same reference numbers.

Detailed description of the invention

A system for disinfecting at least one medium, including a vent, at least one ozone generator, a first ozone sensor for measuring the ozone concentration near at least one ozone sensor, a second ozone generator for measuring the ozone concentration in the vent in the case of a closed environment , a control relay in the case of a closed environment, an air flow sensor in the case of a closed environment, an intermediate controller, at least one intermediate controller for collecting and transmitting data, and a central controller for controlling the ozone generator to generate ozone depending on the measured ozone concentration and the target time of day, filling sensor.

The system monitors the amount of ozone in the disinfected environment around the clock to ensure an optimal balance between effective disinfection and a safe user environment. For example, when the ozone concentration is higher, decontamination is more effective, but maintaining such a high ozone concentration during a time of day when it can affect people creates a higher risk of unpleasant or harmful ozone exposure. This can be avoided, for example, by maintaining a higher ozone concentration at night or at any other time when there are no people in or near the environment to be decontaminated. This can increase the efficiency of ozone generation when controlling microorganisms and pests, but at the same time it must be ensured that the relevant legal thresholds are not exceeded.

The time of day is determined using a timer; the central controller uses its data to control the ozone generators. This is an easy way to control your daily schedule, but other methods can be used. For example, daylight and / or temperature sensors can be installed to distinguish between daytime and nighttime.

The central controller controls the ozone generators according to a programmed schedule and a specified time of day. When programming a time schedule, one or more components are taken into account: season, weekdays, holidays. In this way, the amount of generated ozone is varied depending on the season or the type of employment. For example, at lower temperatures in winter, unpleasant odors from wastewater are less of a problem than in the summer months.

The central controller stops generating ozone in the ozone generator when the ozone sensor detects that the ozone concentration exceeds the calculated stop value in the environment to be disinfected. In this way, excessive ozone generation is avoided, for example, legal thresholds are not exceeded, above which ozone has a noticeable effect on humans.

The concentration thresholds vary with the time of day. When the ozone concentration is high, the concentration threshold is determined in accordance with the statutory threshold values, taking into account the time of day when the ozone concentration is low; the threshold is set so as to prevent human exposure to ozone.

The first ozone sensor is positioned at such a distance from the ozone generator that the ozone can be mixed with the air before the concentration is measured. This achieves a more accurate measurement of the ozone concentration.

In addition, the disinfection system includes a presence sensor designed to detect the presence of people in the environment to be disinfected. As soon as the sensor detects the presence of a person within the disinfected environment, the central controller stops the ozone generators. it

- 4 036680 serves as an additional safety measure: even if ozone is still in the air, it will not be actively generated and will dissipate. Thus, a person present in a disinfected environment can avoid prolonged exposure to high ozone concentrations, which can be harmful to his health. The function of the presence sensor can be performed by at least one motion detector. Various motion detectors can be used, such as infrared, microwave, ultrasonic or tomographic. Other types of motion detectors can be used, such as door-opening sensors, which are triggered when doors in sewage pumping stations are opened. In addition, combined sensors can be used to improve the accuracy of presence detection.

The decontamination system further includes an air flow sensor for measuring the air flow escaping from the environment to be disinfected, for example, in an air vent or an opening with a similar function, and the central controller stops ozone generation if the air flow sensor detects that the air flow falls below a threshold value. Thus, it is possible to quickly determine that the ventilation device for the environment to be disinfected is clogged and to prevent the rapid accumulation of ozone.

The decontamination system further includes a second ozone sensor for measuring the ozone concentration in the vent of the closed environment, and the central controller stops ozone generation if the second ozone sensor determines that the second concentration threshold has been exceeded. This is an additional means of protecting against the formation of excessive ozone concentration in the outlet of the ventilation system.

Preferably, depending on the time of day, it is possible to determine different concentration values for the second threshold value.

The disinfection system additionally includes an intermediate controller that transmits the data received from the system elements directly to the central controller. The central controller provides remote control and management of the disinfection system. The central controller includes an input for receiving feedback data from several different disinfection systems through several intermediate controllers. In this way, data from several sewage pumping stations can be monitored and compared.

Feedback data can be transferred from the intermediate controller to the central controller via cable, GSM module or internet connection.

Examples of

It is understood that many specific parts are presented to provide a complete and detailed description of exemplary embodiments of the invention. However, those skilled in the art can clearly understand that the specific details of the exemplary embodiments of the invention do not limit the use of the invention, which can be used even without such specific instructions. Well-known methods, procedures and components are not described in detail so that examples of the invention are not misleading. In addition, this description should not be considered as limiting the given examples of implementation of the invention, but it should be understood only as a representation of their implementation.

FIG. 1 shows the proposed disinfection system intended for installation in the premises of sewage pumping stations (3). The system includes at least three ozone generators (5, 18), of which at least one ozone generator (18) is suitable for supplying ozone to waste water (17), the first ozone sensor (6), designed to measure the ozone concentration in the waste storage room. water (3), and a second ozone sensor (7), designed to measure the ozone concentration at sewage pumping stations, located in the ventilation hole (1) of the system, an air flow sensor (9), at least one intermediate controller (11) for collecting data and their transmission to the central controller (13), at least one intermediate controller (12) for other rooms, designed to collect data from other identical disinfection systems and transfer them to the central controller (13), the central controller (13), designed to control ozone generators in order to generate ozone depending on the measured ozone concentration and the set time of day, control relay (8), timer (10), at least m There is one presence detector (14), ozone-resistant ozone supply lines (19), holes with reversing valves (21), reversing valves (22).

The disinfection system in accordance with the first modification of the implementation of the invention includes ozone generators (5, 18), which supply ozone to the premises (3) to be disinfected, into the wastewater collection well (16), and also directly into the wastewater (17), and which controlled through a central controller (13). The ozone outlet opening of at least one ozone generator (5) is adapted to direct the ozone flow to the room (3) to be disinfected and / or to the object (4) inside this room to be disinfected. The ozone generated by the increased capacity of the generators (18) exits through ozone-resistant pipelines (19), which can be connected to the ozone outlet head (20) equipped with two openings (21) with reversing valves (22) for the ozone outlet so that these openings do not were clogged with waste water if the ozone generators (18) are shut down.

- 5 036680

In this modification, the central controller (13) is designed to receive control data through the intermediate controller (11) from the timer (10), ozone sensors (6, 7) and the presence sensor (14), as well as through other identical intermediate controllers (12), intended for use in disinfection systems. The central controller (13) is designed to monitor incoming control data and adjust settings centrally by sending commands through intermediate controllers (11, 12) to control ozone generators (5, 18). The central controller (13) provides control and remote control of the disinfection system in sewage pumping stations. The central controller (13) is equipped with an input to receive feedback data from more than one intermediate controllers (11, 12) from many sewage pumping stations. In this way, data from several sewage pumping stations can be monitored and compared. Feedback data can be transferred from more than one intermediate controllers (11, 12) to a central controller (13) using a cable, GSM module or internet connection.

The room to be disinfected (3) contains an ozone sensor (6) designed to measure the ozone concentration inside the room (3), a presence sensor (14) to detect the presence of people in the room (3) and a timer (10). All sensors (6, 7, 14) transmit the collected data to the central controller (13). The first ozone sensor (6) is installed separately from the ozone generator (5) and placed on the wall of the room (3), preferably on the opposite wall of the room (3) from the ozone generator, so that these two devices are located as far from each other as possible. The purpose of this placement is to mix the ozone with room air before the ozone enters the detector. Thus, the ozone sensor (6) installed in the room more accurately measures the ozone concentration.

When the first ozone sensor (6) detects that the ozone concentration in the environment exceeds the calculated shutdown value, the central controller (13) stops the ozone generators (5, 18). With such modifications, there will be no excess ozone generation. This opportunity can be used, for example, to stay within the legal limit values above which ozone is significantly exposed to humans. Preferably, different concentration limits are set depending on the time of day. When the ozone concentration is high, the concentration threshold is determined in accordance with the statutory threshold values, taking into account the time of day when the ozone concentration is low; the threshold is set so as to prevent human exposure to ozone. The first ozone sensor (6) is installed at such a distance from the ozone generators (5, 8) that ozone can be mixed with air before measuring the concentration. This achieves a more accurate measurement of the ozone concentration.

The presence sensor (14) is installed on the wall of the room (3) to be disinfected. The presence sensor (14) is directed to the place where persons entering the room (3) to be disinfected can be fixed. When the presence of a person is detected, the central controller (13) stops the operation of the ozone generators (5, 18). This serves as an additional safety measure, since even if ozone is still in the air, it will no longer be actively generated and will dissipate. Thus, a person present in a disinfected environment can avoid prolonged exposure to high ozone concentrations, which can be harmful to his / her health. The function of the presence sensor (14) can be performed by at least one motion detector. In this way, the presence of people in the room can be recorded by their movements. Various motion detectors can be used, such as infrared, microwave, ultrasonic or tomographic. Other types of motion detectors can be used, such as door-opening sensors, which are triggered when doors in sewage pumping stations are opened. In addition, combined sensors can be used to improve the accuracy of presence detection.

An air flow sensor (9) is mounted on top of the vent (1), attaching it to the vent pipe and used to measure the air flow exiting through the vent (1). As soon as the air flow sensor (9) detects the drop in air flow below the threshold value, the central controller (13) stops the operation of the ozone generators (5, 18). In this way, it is possible to quickly determine that the ventilation system in the sewage pumping station is clogged and prevent the rapid accumulation of ozone.

The system additionally includes an ozone sensor (7) designed to measure the concentration of ozone in the air exiting the vent. It can be installed to measure the ozone level in the air exiting the air flow sensor (9). The control relay (8) is installed to transmit the received data to the intermediate controller (11, 12). The central controller stops the ozone generators (5, 18) when the second ozone sensor (7) detects that the second concentration threshold has been exceeded. This is a second measure of protection against the formation of an unnecessarily high concentration of ozone penetrating through the exhaust port of the building's sewage pumping station. It sets a different second threshold value depending on the time of day. In this way, the system operates more actively at times of day when the ventilation is less likely to open.

- 6,036,680 openings of sewage pumping stations, therefore a higher ozone concentration is created.

The timer (10) is used to control the time of day and control operation based on a time schedule, as well as to transmit data to the central controller (13) to control ozone generators (5, 18) depending on the time of day. The timer of this modification includes a touch screen for entering control options and setting the time schedule program. This is a simple way to control time of day operation according to a programmed schedule and a set time of day. When programming a time schedule, one or more components are taken into account: season, weekdays, holidays. This method provides for variation of ozone generation during the day depending on the season and taking into account the factor of presence. For example, at lower temperatures in winter, unpleasant odors from wastewater are less of a problem than in the summer months.

FIG. 2 shows a disinfection system for installation in wastewater treatment plants (open sump wastewater treatment plants), where certain conditions can lead to the appearance of fungi and / or bacteria and biogas, which can harm human health by spreading in the atmosphere or cause unwanted / unpleasant odors ... The disinfection system of such a modification is installed in the environment to be disinfected, that is, in the wastewater collection and disposal tank and its environment near the collection points.

The disinfection system includes more than one ozone generator (18) suitable for supplying ozone to wastewater (17), ozone sensors (6 ') designed to measure the ozone concentration around the perimeter (3) of the wastewater treatment tank (3'), at least one intermediate controller (11) for collecting data and transmitting it to the central controller (13), at least one intermediate controller (12) for collecting data from other identical disinfection systems and transferring them to the central controller (13), central controller (13 ), designed to control ozone generators to generate ozone depending on the measured ozone concentration and the set time of day, timer (10), at least one presence sensor (14), ozone-resistant ozone supply pipelines (19), ozone outlet head (23) with outlets (21) and reversing valves (22).

The ozone generators (18) supply ozone to the wastewater collection or disposal tank (3 ') to be disinfected, while the central controller (13) controls the ozone generators. Ozone generated by ozone generators (18) is sent directly to waste water (17). Ozone exits through ozone-resistant pipelines (19), which are connected to the ozone outlet head (23), equipped with two openings (21) with reversing valves (22) for the ozone outlet, so that these openings are not clogged with waste water if the ozone generators (18) are shut down work. It is preferable that the ozone generators (18) are made in accordance with the dimensions, atmospheric temperature and humidity of the environment to be disinfected in order to increase the efficiency of the generated ozone in influencing the microorganisms in this environment. At the same time, the effectiveness of ozone as a disinfectant depends on several factors, including the amount of ozone used, the residual ozone content in the environment and other environmental factors such as pH, temperature, amount of organic substances, etc.

The central controller (13) is designed to receive control data through the intermediate controller (11, 12) from the timer (10), the ozone sensor (6) and the presence sensor (14), as well as through the intermediate controllers (12) of other environments where identical disinfection systems. The central controller (13) is designed to monitor incoming control data and adjust settings centrally by sending commands through intermediate controllers (11, 12) to control the ozone generator (8). The central controller (13) provides control of the disinfection system in sewage pumping stations and their remote control. The central controller (13) is equipped with an input for receiving feedback data from more than one intermediate controllers (11, 12). In this way, data from several wastewater treatment plants can be monitored and compared. Feedback data can be transferred from more than one intermediate controllers (11, 12) to a central controller (13) using a cable, GSM module or internet connection.

Ozone sensors (6 ') are designed to measure the ozone concentration in the ambient air and around the protection perimeter, transmitting the received data to the central controller (13). The ozone sensors (6 ') are installed separately from the ozone generators (18) to keep the devices as far apart as possible. This is done so that the produced and not fully consumed ozone, which is intended for the disinfection of wastewater and can potentially enter the surrounding atmosphere, is mixed with the ambient air before entering the ozone sensors (6 '). In this way the ozone sensors (6 ') more accurately measure the ozone concentration. When at least one ozone sensor (6 ') detects that the ozone concentration in the monitored environment exceeds the stop setpoint, the central controller (13) stops the ozone generator (18). This avoids generating excess ozone. Preferably, different concentration limits are set depending on the time of day. Thus, the legal thresholds are not exceeded, above which ozone significantly affects people.

- 7 036680

At least one presence sensor (14) is installed in the environment of the waste water treatment tank (3 '). The presence sensor (14) is directed to the place where the movements of people can be detected. When a person is detected, the central controller (13) stops the ozone generators (18). Thus, a person present in a disinfected environment can avoid prolonged exposure to high ozone concentrations, which can be harmful to his / her health. The function of the presence sensor (14) can be performed by at least one motion detector. Various motion detectors can be used, such as infrared, microwave, ultrasonic or tomographic. In addition, combined sensors can be used to improve the accuracy of presence detection.

The timer (10) is designed to control the time of day and control operation based on a time schedule, as well as to transmit data to the central controller (13) through intermediate controllers (11, 12) to control ozone generators (5, 18) depending on the time of day ... The timer of this modification includes a touch screen for entering control options and setting the time schedule program. This is a simple way to control time of day operation according to a programmed schedule and a set time of day. When programming a time schedule, one or more components are taken into account: season, weekdays, holidays. This method provides for variation of ozone generation during the day depending on the season and taking into account the factor of presence. For example, at lower temperatures in winter, unpleasant odors from wastewater are less of a problem than in the summer months.

FIG. 3 shows a system for the decontamination of a waste storage with garbage chutes. The system includes at least one ozone generator (5), the first ozone sensor (6) designed to measure the ozone concentration in the wastewater storage (3), the second ozone sensor (7), designed to measure the ozone concentration in the ventilation ducts (2) of the storage waste, air flow sensor (9), at least one intermediate controller (11) for collecting data and transmitting it to the central controller (13), at least one intermediate controller (12) for other rooms to collect data from identical disinfection systems and their transmission to the central controller (13), the central controller (13) designed to control the ozone generators to generate ozone depending on the measured ozone concentration and the set time of day, a control relay (8), a timer (10), at least one presence sensor (14).

The disinfection system of this modification is installed in the waste storage (3), connected to the garbage chute (2), which can be accessed through the loading valve (1 '). The ventilation pipe is located on top of the refuse chute (2). When using a waste collection system, the user throws debris through the loading valve (1 ') and it falls down the chute (2) into the waste storage container (4).

The ozone generator (5) releases ozone into the waste storage (3), the central controller (13) controls the ozone generator based on data from the intermediate controller (11). Such data includes data from a timer (10), an ozone sensor (6, 7), and a presence sensor (14). The ozone output of the ozone generator (5) is preferably adjusted to direct the ozone to the waste container (4). The timer (10) must operate on the basis of the time schedule program (13) and transmit data to the central controller (11) to control the ozone generator depending on the time of day. The timer of this modification includes a touch screen for entering control options and setting the time schedule program.

In this modification, the central controller (13) receives control data from the intermediate controller (11) and other intermediate controllers in neighboring identical waste collection systems (12) connected to other disinfection systems located in other waste storage facilities, for example, in the storage facilities of the same building. or a complex of buildings. The central controller (13) monitors the incoming control data and centrally adjusts the settings by sending feedback commands through the intermediate controller (11) to control the ozone generator. As soon as the ozone concentration measured by the ozone sensors (6, 7) falls below the permissible threshold value, the central generator (13) can command the ozone generator (5) to start generating more ozone. This prevents the formation of excessively high ozone concentrations. The central controller (13) is provided with an input for receiving feedback data from more than one intermediate controllers from several waste storage facilities. In this way, data from several waste storage sites can be monitored and compared. Feedback data can be transferred from the intermediate controller (11, 12) to the central controller via cable, via a GSM module or an Internet connection.

All sensors (6, 7, 14) transmit the collected data to the intermediate controller (11), which transmits this data to the central controller (13). The ozone sensor (6) is installed separately from the ozone generator (5) and fixed on the wall of the waste storage (3), farther from the ozone generator and preferably on the opposite wall of the waste storage, so that these devices are as far apart as possible. The purpose of this placement is to mix the ozone with room air before the ozone enters the detector. In this way, the ozone sensor measures the ozone concentration more accurately.

The presence detector (14) is mounted on the wall / ceiling of the waste storage and is designed to minimize the possibility of false alarms such as falling waste or rodent movement. In this modification, this is realized by directing the motion detector to the place where the movement of a person entering the waste storage can be determined. In addition, other technical solutions can be used, such as infrared detectors configured to ignore thermal detection zones that are smaller than those created by human presence. In such cases, only the presence of a person is detected, and the thermal radiation generated by rodents is ignored. The presence sensor (14) is used to detect people entering the waste storage (3): as soon as it is activated, the ozone generator (5) turns off. Although there is still some ozone in the air of the waste storage (3), it is no longer generated; therefore, a person can use the premises safely. In addition, people usually enter the waste storage through the front door, and ozone is released outside when it is opened. Thus, the concentration of ozone in the waste storage decreases even more, and this happens when a person's entrance into the room is detected and ozone is no longer generated. In this way, the concentration of ozone is reduced in the waste storage (3) when people enter the waste storage, for example to empty a container (4) or manually clean the room. This prevents exposure to high ozone concentrations, which can be harmful to human health. With this in mind, the rate at which the ozone concentration declines after opening the front door can help decide which concentration limit should be set. For example, factors such as opening doors to the outside or too large entrance doors of the waste storage facility can cause ozone dispersion from the waste storage facility. Therefore, in the central controller (13), it is possible to set a higher threshold value for the ozone concentration in order to increase the ozone concentration in the waste storage and thus ensure a higher decontamination efficiency. Once people enter the storage facility, the ozone concentration drops to an acceptable level so that they are not harmed. The central controller (13) can control the rate of dispersion of ozone from the waste storage and adjust the predetermined ozone concentration limit accordingly. A variety of presence detectors can be used, such as infrared, microwave, ultrasound, or tomography. Other types of presence sensors can also be used, such as door openers, which are triggered when the doors in waste storage facilities are opened. In addition, combined sensors can be used to improve the accuracy of presence detection.

The air flow sensor (9) is installed on top of the garbage chute (2), connecting it to the ventilation pipe and using it to measure the air flow coming out of the garbage chute (2). The air flow sensor (9) measures the flow of air exiting the chute (2), an obstruction in which can lead to a decrease in the flow through the chute or to its complete retention. In this case, the decrease in the normal air flow is detected by the air flow sensor (9), which reports this to the central controller (13), which can turn off the ozone generator (5) in order to prevent an excessively high concentration of ozone in the building waste storage.

A second ozone sensor (7) measures the ozone concentration in the ventilation opening of the room (3). It can be installed to measure the level of ozone concentration in the air leaving the air flow sensor (9). The control relay (8) is installed to transmit the received data back to the intermediate controller (11). The central controller stops the ozone generators (5, 18) when the second ozone sensor (7) detects that the second concentration threshold has been exceeded. This is a second safety feature that protects the room (3) and the chimney pipe (2) from excessive ozone concentration. It sets a different second threshold value depending on the time of day. In this way, the system operates more actively at times of the day when the storage openings are less likely to open, providing a higher ozone concentration.

The disinfection system monitors and regulates the amount of ozone in the air of the waste storage, and also maintains a balance between the efficiency of disinfection and environmental safety for users of the waste storage. To this end, when the system is running, the timer (10) sends data to the central controller (13) via the intermediate controller (11) in accordance with a time schedule program to control the ozone generator (5) to generate a variable amount of ozone over time; it can also be based on waste collection, air temperature and humidity, and waste disposal frequency with the ability to increase the efficiency of generated ozone when dealing with microorganisms present in the waste collection system. At the same time, the effectiveness of ozone as a disinfectant depends on several factors, including the amount of ozone used, the residual ozone content in the environment and other environmental factors such as pH, temperature, and the amount of organic substances in the waste. For example, for optimum efficiency, the central controller (13) regulates the ozone generator in accordance with the signals from the timer (10). For example, it may turn on the ozone generator (5) at night when the waste storage (3) is not in use, and turn off the ozone generator (5) before daytime, or the ozone generator may remain on but the amount of ozone emitted is reduced. You can also program the timer (10) according to the season, weekdays and holidays. Therefore, timer (10) provides the user with

- 9 036680 for the waste repository the possibility of flexible regulation of the threshold value of ozone concentration in accordance with various environmental factors, own settings and the level of pollution of the waste repository, at the same time, without exceeding the restrictions established by legislation. For this purpose, ozone sensors (6, 7) are used to detect when the ozone concentration exceeds the set limits both in the waste storage (3) and in the garbage chute (2), respectively, and then the central controller (13) turns off the ozone generator (5), to prevent an increase in ozone concentration. Setpoints in higher locations may vary as the waste storage facility (3) can receive a higher ozone concentration than the chute (2), where, in case of high concentration, ozone can penetrate through openings into residential floors of a building. Using a timeline, you can also set different thresholds depending on the time of day. For example, at night, a high ozone limit value is set in accordance with the maximum allowable limit values set by the legislation, and conversely, in the daytime, when people are more likely to use waste storage facilities, a lower ozone limit can be set that will allow residents buildings do not feel the effect of ozone. This is an easy way to control your daily schedule, but other methods can be used. For example, daylight and / or temperature sensors can be installed to distinguish between daytime and nighttime.

FIG. 4 shows a decontamination system for indoor installations where certain conditions can cause the appearance of fungi and / or bacteria, which can pose a risk to human health by spreading in the atmosphere, or at least cause unwanted / unpleasant odors. Such rooms can be used for storing food or non-food products, changing rooms in gymnasiums, etc. The disinfection system of this modification is installed in the premises (3) to be disinfected, which are connected to the ventilation hole (1). The system includes at least one ozone generator (5), a first ozone sensor (6) designed to measure the ozone concentration in rooms (3) to be disinfected, and a second ozone sensor (7) designed to measure the ozone concentration in the ventilation opening (1 ) systems, an air flow sensor (9), at least one intermediate controller (11) designed to collect data and transmit it to the central controller (13), at least one intermediate controller (12) for other rooms, designed to collect data from other identical disinfection systems and their transmission to a central controller (13), a central controller (13) designed to control ozone generators in order to generate ozone depending on the measured ozone concentration and a given time of day, a control relay (8), a timer (10 ), at least one presence sensor (14).

Premises (3) to be decontaminated include areas to be decontaminated, which are accessible to humans or are located near crowded objects, where, under certain conditions, fungi and / or bacteria may appear that may be harmful to human health, or at least cause unwanted / unpleasant odors. Examples of such areas are the rooms of vending machines for collecting empty containers (used packaging materials), when such vending machines are installed to transfer empty containers (used packaging materials) to a waste storage space. These facilities may also include food and non-food storage areas, container / refrigerated trucks, gym locker rooms, and any other facilities or equipment mentioned above.

The central controller (13) controls the ozone generator (5), which dissipates the ozone into the room (3) to be disinfected. The ozone outlet of the ozone generator (5) is adapted to direct the ozone flow into the room to be disinfected and / or to the object (4) inside this room to be disinfected, such as automated container containers, waste processing complexes, equipment for processing food and non-food products etc.

In this modification, the central controller (13) receives control data from the timer (10), ozone sensors (6, 7) and the presence sensor (14) through the intermediate controller (11), as well as through other identical intermediate controllers (12) intended for disinfection systems for adjacent rooms. The central controller (13) monitors the incoming control data and centrally adjusts the settings by sending feedback commands through the intermediate controller (11) to control the ozone generator. The central controller (13) is provided with an input for receiving feedback data from more than one intermediate controllers from several waste storage facilities. In this way, data from several waste storage sites can be monitored and compared. Feedback data can be transferred from the intermediate controller (11, 12) to the central controller via cable, via a GSM module or an Internet connection.

The room (3) to be decontaminated contains the first ozone sensor (6) for measuring the ozone concentration inside the room (3). The first ozone sensor (6) is installed separately from the ozone generator (5); it is mounted on the wall of the room (3) separately from the ozone generator and preferably on the wall opposite to it, so that these two devices are located as far from each other as possible. The purpose of this placement is to ensure that ozone is mixed with room air up to

- 10 036680 ozone hits the detector. Thus, the ozone sensor (6) installed in the room more accurately measures the ozone concentration.

The presence detector (14) is mounted on the wall / ceiling of the waste storage and is designed to minimize the possibility of false alarms such as falling waste or rodent movement. In this modification, this is realized by directing the motion detector to the place where the movement of a person entering the waste storage can be determined. Of course, other technical solutions can be used, such as IR detectors configured to ignore thermal detection zones that are smaller than those created by human presence. In such cases, only the presence of a person is detected, and the thermal radiation generated by rodents is ignored. The presence sensor (14) is used to detect people entering the room (3) to be disinfected: as soon as it is activated, the ozone generator (5) turns off. Although there is still some ozone in the air of the room (3) to be disinfected, it is no longer generated; therefore, a person can use the premises safely. In addition, people usually enter the premises through the front door, and ozone is released outside when it is opened. Thus, the concentration of ozone in the room to be decontaminated decreases even more, and this happens when a person's entrance into the room is detected and ozone is no longer generated. This prevents exposure to high ozone concentrations, which can be harmful to human health. With this in mind, the rate at which the ozone concentration declines after opening the front door can help decide which concentration limit should be set. Therefore, in the central controller (13), it is possible to set a higher threshold value of the ozone concentration in order to increase the ozone concentration in the room to be disinfected, and thus ensure a higher disinfection efficiency. As soon as people enter the area to be decontaminated, the ozone concentration drops to an acceptable level so that they are not harmed. The central controller (13) can control the rate of dispersion of ozone from the room to be disinfected and adjust the preset limit of the ozone concentration accordingly. A variety of presence detectors can be used, such as infrared, microwave, ultrasound, or tomography. Other types of presence sensors can also be used, such as door openers, which are triggered when the doors in waste storage facilities are opened. In addition, combined sensing elements in the sensor (14) can be used to improve the accuracy of presence detection.

The air flow sensor (9) measures the air flow coming out of the ventilation hole (1). If the ventilation hole (1) is faulty, the air flow through the ventilation hole is significantly reduced. In this case, the air flow sensor (9) can detect a decrease in normal air flow and report this to the central controller (13) via the intermediate controller (11). Then the central controller (13) stops the ozone generator (5) in order to prevent an excessively high concentration of ozone in the room to be disinfected.

A second ozone sensor (7) measures the ozone concentration in the vent (1). It can be installed to measure the level of ozone concentration in the air leaving the air flow sensor (9). The control relay (8) is installed to transmit the received data back to the intermediate controller (11). The central controller stops the ozone generator (5) when the second ozone sensor (7) detects that the second concentration threshold has been exceeded. This is a second safety feature that protects the room (3) to be decontaminated and the vent (1) from the formation of an excessively high concentration of ozone. It sets a different second threshold value depending on the time of day. In this way, the system operates more actively at times of day when the opening of the room to be decontaminated is less likely to open, providing a higher ozone concentration.

The disinfection system controls and regulates the amount of ozone in the air of the room to be disinfected, and maintains a balance between the efficiency of disinfection and the safety of the environment using a timer (10), which is programmed according to a time schedule and sends data to the central controller (13) through an intermediate controller (11 ) to control the ozone generator (5) so that it generates a variable amount of ozone depending on time; this can also be done based on the size of the room to be decontaminated, temperature and humidity. At the same time, the effectiveness of ozone as a disinfectant depends on several factors, including the amount of ozone used, the residual ozone content in the environment and other environmental factors such as pH, temperature, and the amount of organic substances in the waste. For example, for optimum efficiency, the central controller (13) regulates the ozone generator in accordance with the signals from the timer (10). It can turn on the ozone generator (5) at night when the room (3) to be decontaminated is not in use, and turn off the ozone generator (5) before daytime, or the ozone generator can remain on, but the amount of ozone released is reduced. You can also program the timer (10) according to the season, weekdays and holidays. Consequently, the timer (10) provides the users of the room to be decontaminated with the possibility of flexible regulation of the ozone concentration threshold value in accordance with various environmental factors, their own settings and the level of pollution of the waste storage, while not exceeding the restrictions established by legislation. To this end, ozone sensors (6, 7) are used to determine when the ozone concentration exceeds the set limits both in the room (3) to be disinfected and in the ventilation opening (1), respectively, and then the central controller (13) turns off the ozone generator ( 5) to prevent an increase in ozone concentration. The setpoints for these locations can be different, as the rooms (3) to be decontaminated can have higher ozone concentrations than the ventilation openings (1). Using a timeline, you can also set different thresholds depending on the time of day. For example, at night, a high ozone limit is set in accordance with the maximum legal limit values, and conversely, in the daytime, when people are more likely to use the room to be decontaminated, a lower ozone limit can be set. This is an easy way to control your daily schedule, but other methods can be used. For example, daylight and / or temperature sensors can be installed to distinguish between daytime and nighttime.

Each individual disinfection system can operate as a stand-alone system, but such a system cannot be error-prone, there may be false alarms due, for example, to power failures, user errors, poor technical conditions, external emissions, lightning strikes or equipment failures. therefore, communication with the central controller (13) provides the ability to remotely control the disinfection systems. This configuration provides round-the-clock monitoring of the decontamination system and responds quickly in case of network failures, for example, when the ozone concentration exceeds the legal limits.

Although in the present description of the invention numerous characteristics and advantages are set forth together with structural details and features, the description is an example of the invention. Without departing from the principles of the invention, it is possible to make changes in details, especially in shape, size and location, in accordance with the most widely understood meanings of the concepts and definitions used in the patent claims. It should be understood that the design of the disinfection system can be changed at least in such a way that several ozone generators and / or ozone sensors will be included, which can be installed in different places in the room or environment to be disinfected, depending on the parameters of the room or environment to be disinfected. to maximize decontamination efficiency within the subject matter of the present invention.
