Description

FIELD OF THE INVENTION The present invention relates to an air aerosol cleaner which is particularly suitable for air and industrial premises such as commercial premises or industrial production premises. BACKGROUND OF THE INVENTION Business premises, such as commercial premises, for example shopping malls, industrial production premises or public premises, such as swimming pools, often have indoor problems. Thus, the pollutants and dust generated by the processes of people and industrial halls visiting shopping malls or public spaces, as well as the pollutants - and the impurities passing into these environments from outside, cause such conditions to be undesirable for such environments. Contaminated general indoor air quality increases the health risks of people living and working in such premises and reduces production efficiency. For air purification, such as general indoor / target exhaust air for shopping malls or factories, there are various cleaning solutions and filtration methods that include different filters and a filter combination to purify indoor / target exhaust air so that it can be recirculated or recirculated after purification. out of jateil- Mana. Impurity restrictions have been set on the quality of waste air in Environmental Protection Act 527/2014 (https://www.finlex.fi/fi/laki/al- N kup / 2014/20140527 # Pidp445860480).

N 2 However, existing cleaning solutions are not always efficient enough to clean indoor / target exhaust air even at the recommended minimum levels, or the solutions in use are not energy efficient or economically viable. Inefficient air cleaning can be caused by, among other things, insufficient air cleaning efficiency or dirt on the filters, as the dirty filter can lose its filtering ability and act as a source of impurities instead of air cleaning. Economic unprofitability, on the other hand, may be due to the fact that insufficiently purified air cannot be recycled back to the premises but must be diverted out as waste air,

whereby, for example, heating cold replacement air in winter or cooling hot air in summer increases energy costs. The economic unprofitability may also be due to the chemicals used in the processes lost with the waste air, ie the material efficiency of production is deteriorating.

Detailed description of the invention

The aerosol cleaner according to the invention, i.e. the aerosol condensate cleaning system, can be used for air purification, such as for cleaning indoor air or target exhaust air in various work and office spaces.

The working and operating spaces, i.e. the operating environments of the aerosol cleaner, can be, for example, different - commercial, public or industrial spaces, where various undesirable conditions for Ima often occur.

People visiting commercial spaces, such as shopping malls, or public spaces, such as sports facilities, as well as pollutants generated by these various activities, as well as contaminants from outside the premises, such as microbes, can cause airborne problems if indoor air is not maintained. sufficiently.

The same applies to industrial premises where, for example, the load of pollutants generated by production processes and various activities, such as gases, steam, dust, particles, etc., is a problem in addition to external pollutants and dust.

Contaminated indoor air increases the health effects of people living and working on the premises and reduces or impairs the functionality and efficiency of production.

For this reason, the indoor air must be cleaned.

The air to be cleaned typically contains aerosols.

An aerosol is a mixture of a gas (s) and small solid particles and / or liquid droplets suspended therein. When using the aerosol cleaner according to the invention for cleaning indoor air and even target exhaust air in work and office premises, the indoor air purification level can be effectively raised to the desired purity level so that the treated air is also sufficiently clean to be safely recirculated to indoor air. If necessary, the air cleaned with an aerosol cleaner can also be directed out. The aerosol cleaner is suitable, for example, for cleaning at least microbes, particles, dust, gaseous organic and / or inorganic compounds from the air. The aerosol cleaner comprises at least a disinfection unit, i.e. means for disinfecting the air to be cleaned in order to kill harmful microbes in the air, a steam humidifier to humidify the disinfected treated air, a condenser for humidifying air, - condensation of the process. The condenser itself does not participate in the air cleaning process and therefore may be located inside the condensate cleaner of the aerosol cleaner or completely outside the aerosol cleaner, even outside the rooms to be cleaned, or both, depending on the desired temperature of the cleaned air. In addition, the aerosol cleaner comprises at least one speed-controlled fan and an automation system controlling the whole. —Aerosol cleaner can be installed both in the room itself or in connection with the air ducts of industrial rooms, eg in the deaeration duct or the recirculated air duct.

N 2 Air disinfection treatment or disinfection method / process for killing microbes, i.e. S microorganisms such as bacteria or viruses, from the air can be I 30 - for example, spraying microbicidal chemicals into the air to be cleaned, i.e. the air to be cleaned in an air duct, UV ultraviolet radiation) to the air to be cleaned in the S air duct or ozonation of the air to be cleaned in the air duct or a combination of the different disinfection methods mentioned above. The disinfection treatment is performed in the immune channel by the disinfection unit of the aerosol cleaner. The disinfection treatment can be selected in advance to suit the respective premises or the disinfection

the method may be varied as necessary, for example, on the basis of microbes or the like present in air or suspected of being present. Also, the chemical to be injected can be selected in advance or the chemical to be used can be selected / varied as needed based on the presence or suspected presence of 5-microbes in the air. The amount of chemical used can also be selected as desired. If there is a lot of microbes in the air, the amount of chemical used can be increased. The chemical used may be, for example, hydrogen peroxide or alcohol. The wavelength of the blue or similar light produced by the UV or UV exposure unit can also be selected / changed according to the microbes, etc. to be irradiated. The exposure unit irradiates the air to be cleaned in the air duct with the desired wavelength of UV light, UV-A, UV-B or UV-C, for example, as well as the desired suitable exposure time and the desired radiation field strength. The UV exposure unit can be implemented, for example, with the help of LED technology. If desired, the chamber of the disinfection unit can also be coated with, for example, self-disinfecting coatings. In addition to the above, the power and exposure time to the ozonator of the ozonator which ozonates the air to be purified in the air duct can be selected as needed. The irradiation time and the exposure time are affected by the flow rate of the air to be cleaned in the air duct and possibly also by the degree of soiling of the air to be cleaned. It should be noted, however, that continuous disinfection of the air is generally not appropriate, but disinfection of the air may be carried out periodically at certain intervals, in pulses or, for example, when the space is off / empty or necessary. The aerosol cleaner may comprise an automation control unit, by means of which, for example, the state and power of the disinfection unit and its timing functions can be controlled.

Means for disinfecting the air to be cleaned to kill microbes in the air may comprise, for example, a chemical sprayer or sprayer for spraying chemicals, a UV light source, for example a UV-LED light source for producing UV radiation, and / or an ozonator or means for photocomposition. to utilize economical solutions, i.e. without a photocatalytic a purification unit. © S If necessary, the air can also be pre-cleaned before the disinfection unit, i.e. N, before its disinfection treatment to kill microbes is started, for example by means of a rotating separator utilizing centrifugal force, various particle fiber filters or the like.

A humidifier, for example a steam humidifier used to humidify the air to be cleaned, either disinfected or non-disinfected, in the air duct to form a sufficiently moist air aerosol mixture, may be any - suitable vapor humidifier with manifolds, e.g. water vapor, the gaseous form of water, is mixed with disinfected or non-disinfected treated air. The idea of the water vapor produced by the steam humidifier is not at this stage to actually wash disinfected microbes or other contaminants from the air to be cleaned, but to humidify the air to be cleaned so that the operation of the condensate cleaner is possible or at least more efficient. With the help of the automation system, in addition to the disinfection unit, the degree of humidification can also be controlled.

A condensate cleaner is a type of drying condensate filter that dries moist air and at the same time removes condensate with air without contaminants. Cold cooling elements, such as a heat exchanger and / or a cooling coil, are used as the condensing surface. This liquid condensed on the surface of the cooling element or elements may be called a condensing liquid. The size or cooling area of the cooling elements used in the condensate cleaner can be selected, i.e. dimensioned according to the need for cleaning or filtration. The cooling energy required by the condensate cleaner can be produced electrically by a cooling machine, heat pump or by circulating cold water cooling water in the condensate cleaner system N or the cooling coil can be connected to the factory cooling water network N, for example, or it can be a separate so-called cooling unit. In order for condensation to occur, the surface temperature S of the cooling coil must be below the dew point temperature of the air to be cleaned. The condensate liquid I 30 is arranged to drain from the cooling coil into a condensate collection tank, which may be an ordinary waste water or rainwater drain or a separate condensate collection vessel. The condensate enters the condensate collection tank S kills microbes and / or other contaminants in the air to be cleaned during the disinfection treatment. In other words, the condensate cleaner cools the humidified air to be cleaned, the aerosol mixture, and binds its impurities to the condensate formed on the surface of the cooling element, e.g. the cooling coil.

into the liquid, in which case the microbes and / or other impurities, such as particles, dust, etc., which have run off with the condensate from the air cleaning process have been removed from the air to be cleaned after the condensate cleaner. The condensate cleaner disinfects the killed microbes by disinfection - i.e. in the case that the air to be cleaned has undergone a disinfection treatment at an early stage of the cleaning process, which is not usually performed full-time on the air to be cleaned. In the refrigeration machine application, the air purifier according to the invention further comprises at least one condenser as part of the condensing process of the air to be condensed and can, if desired, also be used for heating or otherwise benefiting the purified air. Thus, the post-cleaning step is not mandatory, because the air can be made sufficiently clean under certain conditions and / or conditions even without the post-cleaning step. After the condensate cleaner, the air temperature is typically between +15 and 20 ° C in a two-stage case with a cold recovery converter and a cooling coil, and between + 28 and 38 ° C after the condenser placed in the air stream after the condensate section. In addition to the above, the air purifier may already comprise an automation control unit integrated in the above-mentioned aerosol purifier apparatus to control and monitor the various functions of the aerosol purifier. The automation control unit with its associated sensors, etc. can be used to control, among other things, the speed of the fan or fans, the degree of humidification, the timing of chemical spraying, the cooling machine, monitor incoming and cleaned air conditions, etc. The automation unit with control panels can be fixed or mobile. , such as a computer, a server, a portable N computer, etc. 2 S At least one fan adjustable for the suction or pressure side of the condensate cleaner or for both the suction and pressure side can be provided in connection with the aerosol cleaner. The purpose of the fans is to suck in condensate / purified air, whether or not condensed, to pass it through an aero-E cell cleaner and to blow it into the space or ductwork.

N> 35 —The choice of the location of the condenser or condensers and the automation control controlled by the automation control unit can therefore influence

whether the cleaned air blown into the room is either space heating or room cooling. If it is desired to heat the room during the heating season and otherwise cool it, the aerosol cleaner according to the invention may comprise two parallel condensers. The first of the parallel condensers may be located, for example, in the purified air stream, and the second of the condensers may be located outdoors or elsewhere, such as in a warehouse. The outdoor condenser has the following advantages, among others: the heat generated by the condenser in its surroundings is not released inside the premises, but outside them, which is especially desirable in summer, because then the condenser does not heat already hot interiors.

—The condenser installed inside the condensate cleaner has the following advantages, among others: when the condenser heats the condensed air, it also heats the premises, which may be necessary or advantageous, especially in winter.

- In the post-cleaning phase, the air can be post-treated with a post-treatment unit comprising a mechanical filter or filters. The after-treatment unit may have, for example, a HEPA filter and / or a chemical filter, such as an activated carbon filter. The after-treatment unit may also have a monitoring sensor that monitors the purity of the air leaving the after-treatment unit and the duration of the chemical filter. If desired, the post-purification can also be carried out using e.g. photocatalytic solutions, in which case the after-treatment unit comprises means for carrying out photocatalytic solutions.

The aerosol cleaner according to the invention can be used to purify the air to a level where its concentrations of harmful substances are below the Known Harmful Concentration (HTP) values determined for various harmful substances. In Finland, the N HTP values are determined by the Ministry of Social Affairs and Health https://www.tyosuojelu.fi/- 2 / harmful-known-concentrations-htp-publication-updated, http://publications.state- S Council.fi/bitstream/ han- I 30 —dle / 10024/160967 / STM 09 2018 HTPvalues 2018 web.pdf? sequence = 1 & is a Allowed = y. HTP values may change as awareness increases, and this has been the case in the past. The corresponding international limit values can be found at the Internet address: https://www.chemsafe- N typro.com/Topics/EU/GESTIS: International Occupational Exposure Limit - Database html. Below the HTP values is the so-called minimum level of air purification. However, several compounds present simultaneously in the air may also have a mutually reinforcing effect, so that even if the concentration of individual compounds or substances is below a harmful level, together they may form harmful effects.

However, with the aerosol cleaner according to the invention, the air to be purified can be made even cleaner by selecting the disinfection treatment (s) (treatment method, exposure time / amount or intensity), the amount of wetting, the condensate cleaner and / or the filters of the after-treatment unit.

Exemplary embodiments of the invention are shown in Figures 1-4. Figure 1 is a block diagram of an aerosol cleaner 100 according to an example of the invention arranged to clean the indoor air of the space 115.

The aerosol cleaner can be placed, for example, in or in connection with or directly in the air duct of the room to be cleaned, such as a ventilation duct or a separate air cleaning duct.

The aerosol cleaner 100 comprises a disinfection unit 101. The disinfection unit 101 may be a chemical syringe arranged to inject microbicidal chemicals such as HyperDRYMist®, hydrogen peroxide or alcohol or the like into the air to be cleaned, a UV lamp such as LED-UV light. a lamp arranged to UV irradiate the air to be cleaned with UV-A, UV-B or UV-C radiation, an ozonator arranged to ozonate the air to be cleaned, or a combination thereof.

The purpose of the disinfection treatment performed by the disinfection unit 101 is to kill the harmful microbes present in the air to be cleaned.

However, the disinfection unit 101 may not be used continuously, if the disinfection unit 101 is not in use, then the air to be cleaned flows through the disinfection unit 101 without disinfection to a humidifier 103 such as a steam humidifier.

Reference numeral 102 may denote, for example, the chemical stock of N disinfection units 101 or the like.

However, the chemical storage 102 is not a mandatory part of the aerosol cleaner 100, for example, when the disinfection unit is a UV lamp or an ozonator, or when the chemical storage is an integrated part of the disinfection unit 101. After the disinfection unit 101, the aerosol cleaner 100 thus comprises a vapor humidifier. a humidifier 103 arranged to humidify the air to be cleaned to a sufficient humidity before the condensate cleaner 106. The parts of the steam humidifier 103 may be N steam generating unit 104 and a manifold 105 to allow a uniform and substantially full air flow of steam to the air to be cleaned.

to the stream. The manifold 105 comprises openings at different heights so that the steam reaches different heights of the air flow, i.e. humidifies the air as evenly as possible. After humidification by the steam humidifier 103, the humidified air to be cleaned flows to the condensate purifier 106. The condensate purifier 106 may comprise at least a cold recovery exchanger 107 and a cooling coil 108. The condensate purifier 106 cools and dries the air as the humidified gaseous particles and condenses on the surface of the cooling elements, i.e. first on the surface of the recovery exchanger 107 and in the second stage on the surface of the cooling coil 108. From the condensate cleaner 106, the condensate flows into the collecting tank, in this case into the drain 109. The condensate also drains into the drain 109, at least to a large extent, of microbes killed by the disinfection unit 101 and other contaminants contained in the condensate unit 106 when it enters the condensing unit 106.

The air cleaned and dried by the condensate cleaner 106 is transferred by the fan 116 on the suction side of the condensate cleaner 106 either to the space 115 directly or to the after-cleaning unit 112. In this example, the condenser 111 condenser is located outside the space 115. / hotter than the desired temperature level. The post-treatment unit 112 is thus an optional part of the aerosol cleaner 100. In this example, the condenser 111 is an external condenser unit of the cooling machine of the condensate cleaner 106, which is located outside the space 115 to be cleaned. The post-treatment unit 112 may include, for example, a HEPA filter 113 and / or an activated carbon filter 114 with a post-filter, and N is thus an optional part of the aerosol cleaner 100. The various N functions of the aerosol cleaner 100 can be controlled by an automation control unit 117. Automation control unit 117 with sensors (not shown) can control, for example, the speed of the fan 116 S, the degree of wetting provided by the steam humidifier 103, the timing of the chemical spraying of the disinfection unit 101, the wavelength and duration of UV exposure or the ozonator ozonation power and the time and purge time, and so on.

The aerosol cleaner 100 of Figure 1. The aerosol cleaner 200 comprises a disinfection unit 201. The disinfection unit 201 may be a chemical syringe, a UV lamp, an ozonator, or a combination thereof. Reference numeral 202 may denote, for example, the chemical storage conditions of the disinfection unit 201. After the disinfection unit 201, the aerosol cleaner 200 comprises a steam humidifier 203. The steam humidifier 203 comprises a steam generating unit 204 and a manifold 205. After humidification of the steam humidifier 203. the dense cleaner 206 condenses the humidified air first on the surface of the recovery exchanger 207 and in the second stage on the cooling coil 208. From the condensate cleaner 206, the condensate water drains into the drain 209. The condensate also drains into the drain 209, at least to a large extent, of microbes and other contaminants killed by the disinfection unit 201 and compounds contained in the air stream to be cleaned when entering the condensate unit 206. The air cleaned and dried by the condensate cleaner 206 flows to the condenser 211 of the cooling machine by means of a fan 216. In the condenser 211, the air is heated. The purified air heated in the condenser 211 is blown into the space or it is blown into the space only after the after-treatment unit 212. The post-treatment unit 212 is thus still an optional part of the aerosol cleaner 200. In this example, the condenser 211 is a so-called an internal condenser unit located - in connection with the aerosol cleaner 200. The post-treatment unit 212 may include, for example, a HEPA filter 213 and / or an activated carbon filter 214 with a post-filter. 2 S In this example, too, the functions and operation of the various parts of the aerosol cleaner 200 can be controlled by the automation control unit 217. The automation control unit a 217 with its sensors (not shown) can, for example, control the operation of the fan 216, the steam humidifier 203 and / and monitor the conditions of the air entering and purifying the aerosol cleaner S, etc.

The aerosol cleaner 300 is very similar in location and construction to the aerosol cleaners 100, 200 of Figures 1 and 2. The aerosol cleaner 300 comprises a disinfection unit 301. The disinfection unit 301 may now be a chemical syringe, a UV lamp or an ozonator, or some combination thereof. Reference numeral 302 may denote, for example, the chemical storage of the disinfection unit 301 or the like. However, the chemical storage 302 is not a mandatory part of the aerosol cleaner 300, for example when the disinfection unit is a UV lamp or ozonator or when the chemical storage is an integrated part of the disinfection unit 301. The steam humidifier 303 comprises a steam generating unit 304 and a manifold 305. After humidification by the steam humidifier 303, the humidified air to be cleaned flows to the condensate cleaner 306. The condensate cleaner 306 may comprise at least a cold recovery cooler 308 and a cooling element 308. The condensate cleaner 306 first condenses the humidified air on the surface of the recovery exchanger 307 and in the second stage on the surface of the cooling element 308. From the condensate cleaner 306, the condensate flows into the drain 309. With the condensate, the microbes and other contaminant particles killed by the disinfection unit 301, which were contained in the air stream to be cleaned when entering the condensing unit 306, also flow into the drain 309 at least to a large extent. The air cleaned and dried by the condensate cleaner 306 flows through a condenser 310 located inside the condensate cleaner of the refrigeration machine, which either heats the air or does not change the air temperature at all. If there is no or little need for heating, the external condenser 311 cools the N cooling machine either alone or together with the condenser 310 N under the control of the automation control unit 317. The purified and possibly heated air in the condenser 310 can be blown into the space 315 or it S can be blown into the space 315 only after the after-treatment unit 312.
