Abstract

FIELD: medicine; medical engineering. SUBSTANCE: method involves producing ultraviolet radiation using isolated medium placed between walls of internal and external reservoir. The fluid medium flows in the internal reservoir and ultraviolet radiation passes through internal reservoir walls transparent to ultraviolet radiation from all sides. Circular maximum ultraviolet radiation concentration is created and the fluid medium is disinfected. Next to it, the radiation passes through walls transparent to it on all sides and enters the isolated medium producing ultraviolet radiation. Resulting ultraviolet radiation is transformed by luminescent material layer coating internal walls of external reservoir into visible light radiation or into erythematous radiation. Device has two reservoirs. The external reservoir having closed end faces is manufactured from material transparent to light, its internal side being covered with luminescent material layer. The internal through reservoir is manufactured from material transparent to ultraviolet radiation, its open end faces being brought outside, beyond the external reservoir space. Isolated medium filling space between the walls of both reservoirs produces ultraviolet radiation. EFFECT: enhanced effectiveness of disinfection; lower power consumption; solved problem of contaminating and cleaning luminescent material layer. 12 cl, 2 dwg

Description

 The invention relates to the disinfection of a fluid, in particular air, water, gases, individually or together, and lighting, and can be used for lighting and disinfection of a fluid in medical, child care facilities, and other locations of people to whom increased requirements for disinfection air, water, etc., which must be constantly or temporarily illuminated by electric light sources.

 In some cases, there is a need for disinfection and lighting of the aquatic environment (for example, in pools designed for swimming people). In this case, the disinfecting medium is water.

 It may also be necessary to disinfect two media at the same time (for example, if in the pool complex it is necessary to disinfect the air, in addition to the illuminated and disinfected water). In this case, disinfection of air and water at the same time is carried out in one device.

The prior art methods and devices for the disinfection of a fluid, in particular water, air, etc., as well as methods and devices for lighting, using ultraviolet emitters. For instance:
Known lighting with lamps (such as DRL, LD, LB), which use UV - radiation (ultraviolet radiation). When they function, UV radiation exists inside the lamp housing in an absolutely sealed space; a layer of luminescent material is deposited on the inner surface of the glass bulb, which converts UV radiation into visible light. Inside the glass bulb of the lighting lamps there are mercury or deuterium vapors; there is no possibility of communication both with the external atmosphere and with liquid media. Electricity consumption is determined by the power of the lamp, the lighting requirements at the places of its application.

 There is also a method for disinfecting air (US 5399319, 1995) using an apparatus that is a vertically mounted UV shielding casing, in which a UV radiation source is placed along the longitudinal axis, mesh filters and a fan forming a flow are placed on the ends of the casing air along the casing. The device has a fairly large air purification capacity. The degree of air purification does not exceed 70% of the total number of microorganisms in the volume of the room. You can not use UV radiation for lighting in such devices.

 There is also a method on which the device for disinfection is based (for example, a structural element of the Baykanur installation developed by the State Scientific and Practical Center named after MV Khrunichev together with NIIKAM CJSC), which differs fundamentally from the above in that water acts as a disinfectable medium.

 Known is a combined method of disinfection and sterilization of indoor air (Japanese application 63-51025), which uses a bactericidal lamp (emitting a mercury line of 254 nm) in addition to an ozonizing lamp. Using the switch, either an ozonizing lamp (in the absence of people in the room) or a bactericidal lamp (in the presence of people) is turned on. In the latter case, there is a weak deodorizing and bactericidal effect from exposure to ultraviolet radiation.

 A variety of methods for disinfection is a method using open unshielded sources of ultraviolet radiation. UV radiation in them acts on the internal volume of the room. This eliminates any prolonged stay of people, because High-intensity UV radiation causes melanoma (skin cancer). Devices of this type are “open” UV emitters of the OBN-P type (the SPT Spetstekhsvet catalog, 1999, p. 11), designed for rapid disinfection of a room in the absence of people, which significantly limits the use of these devices in time (use is possible only in lack of staff). In addition, due to the need to turn off OBN-P devices for the duration of the presence of people, the degree of air purification with their help may not be high enough for use, for example, in operating rooms. Based on the foregoing, the effectiveness of the use of such products decreases, because after the disinfection process, the internal volume of the room is again filled with undesirable microbioflora and microorganisms for humans. This method of applying UV radiation also excludes the implementation of the lighting function to some extent.

 Closest to the proposed is a method of disinfection of air in hospital premises using a device containing a UV radiation source, power supply unit, a casing of translucent material, coated internally with a phosphor (RU 19468, Prokhorov A.M., Vlasov D.V., Solomatin V .A., 09/10/2001). In this device, it is possible to simultaneously perform the functions of lighting and disinfection, due to the conversion of part of the UV radiation into visible light. However, the fundamental principle of operation of the known device is significantly different from the principles of the invention. The implementation of the lighting and disinfection functions in it is determined by two integrated structural systems. As a result, the overall technical result from the operation of the known device also differs significantly from the technical result obtained in the invention, since the latter is based on new knowledge, first discovered by the authors themselves. The known device has a fundamentally lower efficiency, limited functionality for disinfection, as well as a narrowly limited scope.

 All this leads to some inconvenience of its practical application. Also in this type of device, there is the problem of contamination of the luminescent material, designed to convert ultraviolet radiation into visible, on the inner side of the translucent casing. Since industrially applied methods do not provide the necessary degree of adhesion of the luminescent material with a translucent casing, mechanical cleaning becomes practically impossible. This problem has not been finding the optimal solution for a long time (since the developed methods for stable fixing of luminescent material require the use of expensive quartz glass or complex binders that quickly lose their properties under these conditions) and largely determine the impossibility of mass introduction of devices that perform disinfection and lighting.

 The technical result of the invention consists in increasing the degree of disinfection of the fluid, saving energy resources, simplifying and cheapening industrial production, increasing usability, reducing the unprofitable effect of ultraviolet radiation and significantly increasing light output, solving the problem of pollution and cleaning of the converting luminescent material.

 The technical result of the invention consists in a qualitative improvement of the basic performance characteristics compared to devices with similar functions, cheaper industrial production and operation.

 The technical result is achieved in that in a method for disinfection of a fluid and simultaneous lighting, including generating ultraviolet radiation, transporting a fluid and disinfecting it, converting ultraviolet radiation by a layer of luminescent material, according to the invention, ultraviolet radiation is generated by an isolated medium located between the walls of the external and internal containers, fluid flows in the internal container, ultraviolet radiation passes through transparent For ultraviolet radiation, the walls of the inner vessel from all sides, create a circular maximum concentration of ultraviolet radiation and disinfect the fluid, and then again pass through the walls of the inner vessel, transparent to ultraviolet radiation, from all sides, into the insulated medium that generates ultraviolet radiation, the total ultraviolet radiation enters on the layer of luminescent material of the inner walls of the outer container, where it is converted into light in the visible region of the spectrum or itemnoe radiation.

 It is possible to control the concentration of ozone entering the environment.

 Additionally, it is also possible to clean the fluid with mechanical or electrostatic filters.

 As a fluid, the use of air and / or water is possible.

 In the method, it is possible to stabilize the flow of ultraviolet radiation.

 The technical result is achieved by creating a device for implementing the proposed method, while a device for disinfecting a fluid and simultaneous lighting, containing an external container of translucent material, coated with luminescent material from the inside, with the possibility of converting ultraviolet radiation coming from the inside, an internal container of material transparent to ultraviolet radiation , and a system for creating a fluid flow, according to the invention, the ends of the external container are sealed They introduced electrodes to ensure that current was conducted from the external medium to the internal one, the internal container was made through, with open ends extended outside the outer bulb, to ensure the tightness of the space between the two containers, and the medium directly generating ultraviolet was located in the space between the two containers radiation, and the system for creating a fluid flow is hermetically connected to the internal container.

 The device can be equipped with a standard base with an integrated electrode.

 The device can be equipped with a system for creating a fluid flow, made with the possibility of forcing at least two different or similar fluids at the same time.

 Electrostatic filters can be installed in the device.

 Mechanical filters may be installed in the device.

 It is also possible to supply it with a system for monitoring the concentration of ozone entering the environment.

 The device can be equipped with an electronic ballast with a sensor on the ultraviolet radiation receiver for a range in the wavelength range of 180-440 nm, to stabilize the ultraviolet radiation flux through appropriate changes in the supply current and voltage.

These qualitatively new technical results are achieved by the joint action of the following groups of functionally independent features:
1. Direct generation of ultraviolet radiation by an isolated medium enclosed in a closed volume, and brought into working condition using a converted electric current.

 2. The conversion of ultraviolet radiation into visible, using luminescent material deposited on a translucent base.

 3. Creating a fluid stream by devices for creating a fan or compressor type stream.

 4. Transporting the fluid stream inside the source of ultraviolet radiation, using a through container of a material transparent to ultraviolet radiation, placed inside the source of this radiation.

 All this made it possible to create a unique circular maximum concentration of ultraviolet radiation in the volume of the disinfectable fluid, to realize almost complete absence of ultraviolet radiation losses when performing the functions of lighting and disinfection, to significantly increase the degree of disinfection of the fluid, to save energy resources, and also to solve the problem of pollution and cleaning of the converting layer of luminescent material.

 In the process of scientific and technical work, the authors in the prior art introduced new knowledge about the possibilities of transporting a fluid inside a source of ultraviolet radiation, for the needs of disinfection, so that the transport system does not serve as an obstacle for ultraviolet radiation to enter the fluid through it. A device was developed that enabled the method.

 As a result of scientific and technical research, the authors introduced new knowledge into the prior art. A device was developed that allows the method to be implemented, which is a source of ultraviolet radiation, equipped with a system for converting ultraviolet radiation into visible, inside which a system for transporting a fluid was created, and in such a way that, while maintaining complete tightness of the internal environment of the source, almost complete permeability of the transport system for ultraviolet, and the circular maximum concentration of ultraviolet radiation inside the transport system emy first obtained in the invention will bring a new level as a function of disinfection, and the degree of luminosity in the implementation lighting function, resulting in a sharp decrease in losses (use of nonuseful) ultraviolet radiation. Thus, at a qualitatively new level in the invention, the functions of disinfecting the fluid and simultaneous lighting are provided. In addition, the proposed constructive solution made it possible for the first time in the class of devices for lighting and disinfection to isolate the converting layer of the luminescent material from an external and disinfectable fluid, thus solving the main problem of such devices - the problem of contamination and cleaning of the converting luminescent material. In the process of scientific and technical work, the authors introduced new knowledge into the prior art about the possibility of creating a UV-transparent transport system for a fluid inside an ultraviolet radiation source, which, with previously unknown success, can be used for disinfection purposes, with a general reduction in the harmful effect of ultraviolet radiation and, therefore, a significant increase in light output of the device compared to analogues.

In the proposed invention, in comparison with existing devices for simultaneously performing the functions of lighting and disinfection, the following new technical results are achieved:
- Almost complete absence of ultraviolet radiation losses when performing device functions.

 - Repeatedly increased degree of disinfection of the fluid.

 - Saving energy and other industrial resources at the manufacturing stage of the device.

 - Ease of use.

 - Saving energy resources at the operation stage.

 - The solution to the problem of contamination and purification of the converting luminescent material.

These qualitatively new technical results are achieved by the joint action of the following groups of functionally independent features:
1. The source of ultraviolet radiation, characterized by a medium directly generating ultraviolet radiation, enclosed in a closed volume, and brought into working condition using a converted electric current.

 2. Systems for converting ultraviolet radiation into visible, characterized by a luminescent material deposited on a translucent base.

 3. Systems for creating a fluid flow, characterized by devices for creating a flow of a fan or compressor type.

 4. Permeable to ultraviolet radiation system for transporting air flow inside the source of ultraviolet radiation, characterized by a through volume of a material transparent to ultraviolet radiation, placed inside the source of this radiation.

 All of the above functionally independent groups of signs, except the last, are known in the prior art. The creation of the last functionally independent group is based on the knowledge first discovered by the authors about the possibility of creating transporting systems inside ultraviolet radiation sources while fully preserving the primary functional qualities of the source. For the first time in the prior art, the authors have overcome the prejudice that it is impossible to create a transporting system inside ultraviolet radiation sources, and its application in this field for the first time allowed achieving the claimed technical results. Thus, the device has a qualitatively new design feature - a system for transporting a fluid inside sources of ultraviolet radiation.

 In addition, the constructive relationship between these groups of functionally independent features (mutual functional arrangement and connection), first proposed by the authors in the invention, allowed us to create a unique circular maximum concentration of ultraviolet radiation in the volume of the disinfected fluid.

 Due to the use by the authors of these new knowledge of the prior art, the invention achieves the previously unknown technical result technical result.

 The device also cannot be obtained by simply combining the existing features, and its technical result cannot be predicted in advance using the laws known in the prior art, since examples of creating a fluid transport system inside an ultraviolet radiation source were not known to the present invention, but the creation of such a system does not in any way determine the technical results obtained in the invention, in particular, the almost complete absence of ultraviolet and radiation when performing the functions of the device, a greatly increased degree of disinfection of the fluid, saving energy and other industrial resources at the stage of manufacturing the device, ease of use, saving energy resources at the stage of operation, as well as solving the problem of pollution and cleaning of the transforming layer of the luminescent material.

 A qualitatively new method and device determines the practical absence of its conceptual analogues. Thus, in the prior art there are only fundamentally different devices with similar functions.

 To demonstrate the feasibility of the device, a schematic version of a general view of the device is shown.

 The drawings show schematic diagrams of the device: in Fig.1 is a schematic diagram of a General view of the device; figure 2 is a schematic diagram of a view of the device in cross section. The drawings do not indicate specific schemes for connecting the device to power sources and the sources themselves.

 The invented device consists of two containers in the form of flasks: an external (1) with closed ends made of translucent material, on the inside of which a layer of luminescent material is applied (2), and an internal (3) through, made of a material transparent to ultraviolet radiation , the open ends of which are outside the outer bulb, and inside the outer bulb (in the space between the walls of the two flasks) there is an isolated medium that directly generates ultraviolet radiation (4), with into it with electrodes (5) to ensure the function of conducting electric current from the external environment without violating the isolation, which, in turn, is achieved by using the cap (6), and in the inner bulb there is a flow of fluid that must be disinfected by the system creating a fluid flow (7).

 The device operates as follows.

 In the sealed space between the walls of the two flasks, external (1) and internal (3), there is a medium that directly generates ultraviolet radiation (4). Ultraviolet radiation (10), incident on the walls of the outer bulb (1), is converted using a layer of luminescent material (2) into the light of the visible region of the spectrum or erythema radiation (9). The system for creating a fluid flow (7) provides the movement of the fluid (8) through the transport system, that is, its passage through the inner flask (3). When ultraviolet radiation (10) passes through the walls of the inner bulb (3), a circular maximum concentration of ultraviolet radiation appears inside it, since the radiation penetrates the volume from all sides. Thus, disinfection of the fluid occurs in the inner flask (8). The ultraviolet radiation (10) passing through the transparent flask (3) and the fluid (8) inside it again passes through the medium directly generating ultraviolet radiation (4) and enters the conversion layer of the phosphor (2), where it is converted into visible light spectrum or erythema radiation (9).

Thus, in the invention the following technical results will actually be realized:
- Almost complete absence of ultraviolet radiation losses when performing device functions.

 Achieved due to the fact that the described constructive solution proposed by the authors solves the problem of the unfavorable scattering (loss) of ultraviolet radiation into the environment and its absorption by previously necessary structural (in existing devices with similar functions) elements.

 - Repeatedly increased degree of fluid disinfection.

 This is achieved due to the fact that the constructive solution proposed by the authors allows the disinfected fluid to be placed directly inside the ultraviolet radiation source, thereby ensuring a circular maximum concentration of ultraviolet radiation in the disinfected fluid.

 - Saving energy and other industrial resources at the manufacturing stage of the device.

 - Ease of use.

 Achieved due to the fact that in the qualitatively new constructive solution proposed by the authors, the number of working structural elements has been significantly reduced, and the connections between them are much simpler than in existing analogues.

 - Saving energy resources at the operation stage.

 Achieved due to the fact that the constructive solution proposed by the authors, due to the realization of the maximum circular concentration of ultraviolet radiation and the absence of ultraviolet radiation losses, allows for the same energy consumption as in existing analogs, to provide a significantly higher degree of disinfection and light output.

 - The solution to the problem of contamination and purification of the converting luminescent material.

 Achieved due to the fact that the constructive solution proposed by the authors, in particular, its element, the fluid transportation system inside the ultraviolet radiation source, made it possible to isolate the transforming layer of the luminescent material from the external and disinfected fluid.

 An outer bulb made of a material that is transparent to visible light or erythema radiation, can, for example, be made of glass (used in the manufacture of domestic fluorescent lamps such as LD or LB), quartz glass, fiberglass, plexiglass or other transparent light visible spectral region or erythema radiation of materials.

 The inner bulb made of a material that is transparent to ultraviolet radiation can be made of quartz glass (used in the production of domestic quartz lamps such as DB-15 or TUV30 lamps made by PHILIPS), in some cases from plexiglass, or other materials that are transparent to ultraviolet radiation.

 As luminescent material can be used, for example, calcium halophosphate activated by antimony and manganese (L-35M), the radiation of which is in the visible region of the spectrum ("Phosphors and chemicals. Information and Technical Bulletin, part 1, Stavropol, 1990 )

 The system for creating a fluid flow can be, in particular, based on the use of electric fans.

 An environment that directly generates ultraviolet radiation can be created according to the principle on which the functioning of fluorescent lamps (lamps of the type LD, LB, DB, TUV) is based. The principle is described in detail in the materials "Spectroscopy of a vacuum ultraviolet", A. N. Zaidel, E. Ya. Schreider. M., publishing house "Science", 1967; "Optical spectrum of atmospheric gases." Novosibirsk, publishing house "Science", 2000

 In the volume in which it is supposed to create a medium that directly generates ultraviolet radiation, 4 output electrodes are inserted, two on each side (for example, using a standard base with built-in electrodes used, for example, in TUV30 lamps) or directly). The electrodes on each side of this device are connected by filaments, which, when heated, emit free electrons, which facilitates the "ignition" of the discharge, i.e. the formation of a plasma glowing column along the entire length of the device. Most often they realize a medium that directly generates ultraviolet radiation in fluorescent lamps using mercury vapor, which is cheaper with the proven technology than, for example, using hydrogen or deuterium; at a vapor pressure of mercury, as a rule, of the order of several millimeters of mercury. The lamp is connected to the 220 V network through a current-limiting ballast, most often a choke.

 When operating devices for the needs of lighting and disinfection, there is a certain problem associated with the nature of the implementation of the medium directly generating ultraviolet radiation. When using discharge radiation to disinfect fluids, the error in the dose of ultraviolet radiation is not easy to predict accurately.

 This problem is easily resolved due to the deliberate design increase in the planned dose. However, there are known developments (for example, "Power semiconductor devices", Voronezh, 1995, translated from English. / Edited by Tokorev, 661 pp.), Which allow the production of a medium directly generating ultraviolet radiation to replace the inductor with electronic ballast, much smaller and weight, allowing electronic stabilization of the discharge through feedback on the discharge current. In this example, an ultraviolet radiation sensor (on a UV receiver in a predetermined range of 200-300 nm) is realized in an electronic ballast, and the electronic ballast stabilizes precisely the ultraviolet radiation flux by means of corresponding changes in current and voltage on the ultraviolet lamp. The principle of operation of such systems is known in the art, but has never before been used to accomplish lighting and disinfection tasks.

 Our studies, when using such a system in the invention, allowed us to single out a new technical result that was not previously determined by its use - a qualitative decrease in the range of possible deviations from a given degree of disinfection during the operation of the invention and, as a result, an increase in the efficiency of the invention by reducing the reserve for the design dose. Another additional technical result is a possible significant increase (several times) in the service life.

 The invention is intended to be installed in a specially manufactured or standard lighting fixture (for example, designed by type of lighting fixtures designed to install standard fluorescent lamps such as LD or LB). The main structural elements of such a device are: a core or substrate (most often made of metal or plastic) that performs a bearing function, elements of an electrical power system (most often based on the use of chokes), a system for creating a fluid flow (most often consisting of one or more fans installed at the inlet of the fluid transportation system), cartridges and fasteners for securing the device (in standard lighting devices - a fluorescent lamp), in large most cases translucent protective casing (often performed plexiglass or fiberglass fabric materials) and reflectors. All the described elements of the lighting device, as well as methods for their installation and operation, are known in the prior art and are widely used in everyday life.

 For standardization, the device can be equipped with a standard base (which are used in domestic fluorescent lamps), since the creation of a medium directly generating ultraviolet radiation can be performed according to the principle used in fluorescent lamps, and its dimensions can be optimized for installation in some existing lighting fixtures.

 In some cases, when using the device, there is no need for a full glow (for example, for decorative purposes), or there is a need for others to receive doses of erythema radiation (for example, in areas where people have a reduced dose in the erythema region of the spectrum, that is, in areas with insufficient solar radiation in ultraviolet and spectral regions close to it: regions of the far north, specific industries); in areas with the need for an increased erythema dose (kindergartens, health-improving medical institutions). In this case, the outer bulb can be coated from the inside with a non-luminescent material that converts ultraviolet radiation to visible (for example, calcium halophosphate activated by antimony and manganese (L-35M), the radiation of which is in the visible region of the spectrum, “Phosphors and chemicals.” Information technical bulletin, part 1, Stavropol, 1990), and was coated with other existing luminescent materials with other required basic characteristics (for example, barium silicate, activated lead (A-33), the emission of which is in the erythemic region of the spectrum "Phosphors and chemicals." Technical Information Bulletin, Volume 1 Stavropol, 1990). As a material for such a flask can also be used, for example, plexiglass with the necessary properties, or other materials.

 In some cases, additional purification of the medium is necessary. In this case, mechanical (based, for example, on the use of membranes) or electrostatic filters (for example, constructed according to the type of household air purifier EFVA Super-Plus ME-10 can be additionally installed on the way the fluid moves to its entrance to the disinfection zone) )

 In some cases, there is a need to implement an increased degree of disinfection (for example, in conditions of increased infection). In such cases, it is advisable to combine two or more devices, connecting their transport systems in series or in parallel, for which the device can be additionally equipped with special rubber or plastic pipes.

 In some cases, it becomes necessary to create separate transport systems for the fluid (for example, when disinfecting water and air at the same time). In this case, two or more flasks that are transparent to ultraviolet radiation can be installed inside the outer flask, and the device will be equipped with two or more separate systems for creating a fluid flow.

 The device can be additionally equipped with systems for monitoring the concentration of ozone released during disinfection of the fluid in the described manner (for example, a mass spectrometer, as well as chemical or semiconductor sensors, "stratospheric ozone" is published on the website http: // cee. Gsfc.naso.gov / edu / sees / strat).

 Connections of the conductive elements of the device are sealed.
