Definitions
- UV lamp module and its use
- the present invention relates to a UV radiator module for ultraviolet irradiation of a substrate, comprising a watertight housing surrounding a radiator arrangement comprising a plurality of mercury low pressure lamps each having a longitudinal axis, and a bottom, a top and at least two the underside and the top side interconnecting side walls and at the bottom has a closed by a beam exit window jet outlet opening.
- the invention relates to a use of the radiator module.
- UV lamp modules are used, for example, in air conditioning and drinking water systems as well as in food production for disinfection.
- Foods such as fruit and vegetables are irradiated, as well as machine parts, packaging materials, liquids, air and surfaces that come into contact with the food during preparation.
- Microorganisms such as pathogens, in particular bacteria or viruses, are inactivated by the ultraviolet radiation.
- UV emitters suitable for sterilization are, for example, mercury vapor discharge lamps, which can be designed as low-pressure radiators, medium-pressure radiators or high-pressure radiators.
- mercury vapor discharge lamps have a cylindrical quartz glass lamp tube with two electrodes arranged therein. The lamp tube is on both Ends gas-tight, for example by means of a pinch, through which a power supply for electrical contacting of the electrodes is performed.
- the filling gas is mercury and usually a noble gas.
- a mercury depot which can consist of pure mercury or a mercury amalgam, is often introduced into the lamp tube.
- Mercury vapor discharge lamps show an emission spectrum with characteristic lines at 254 nm (UV-C radiation) and optionally 185 nm (VUV radiation).
- radiant modules are classified by guidelines for the degree of sealing (degree of protection) that the radiator module housing must have.
- the division takes place in so-called IP codes (International Protection Code) with two-digit code numbers.
- IP codes International Protection Code
- the first indicator relates to the degree of protection against foreign bodies such as dust particles; the second code indicates the degree of protection against water.
- emitter modules with UV emitters are used, for example, for disinfecting containers or packaging for food, they must be housed in a housing which is dust-tight;
- the first IP code is then 6.
- the housing must provide protection against the ingress of a cleaning fluid such as water, hydrogen peroxide or caustic soda, which is expressed by the second digit, which characterizes in particular the sealing of the jet exit window in the housing.
- a cleaning fluid such as water, hydrogen peroxide or caustic soda
- the reduction of the number of bacteria depends on the radiation dose arriving at the substrate. This is determined by the irradiation power of the UV radiator module and by the duration during which the substrate is exposed to UV radiation. In systems in which the substrate is moved along the UV radiator module, an extension of the irradiation time results from the fact that several UV radiators in a UV radiator module are combined to form a planar, planar arrangement.
- An embodiment of such a UV radiator module, designed for use in a disinfection system with a disinfection station, is described in DE 20 2017 101 112 U1, from which a UV radiator module according to the aforementioned type is also known.
- a total of eight UV lamps are arranged in the form of low-pressure mercury lamps, each having a radiator cladding tube with a circular cross-section.
- the longitudinal axes of the radiators are parallel and in a common radiator plane, so that they form a total surface radiator arrangement.
- the metal housing has a bulged upward housing upper part to which a housing lower part is screwed, in which a quartz glass is held as a jet exit window.
- the quartz glass plate rests on a circumferential shoulder via a sealing ring and is pressed onto the sealing ring by means of a mechanical hold-down. This seal easily withstands the cleaning cycles with heavy jet water, as is common, for example, in plants of the food industry, so that the spotlight module is permanently suitable for use under the hygiene standard IP66.
- the UV radiator module is arranged in the disinfection system in such a way that irradiation of the substrate takes place at least in one irradiation area with a predetermined minimum irradiation dose. From a cost point of view, there is a tendency and for reasons of space often even the requirement to keep the number of UV lamps as low as possible in favor of the use of powerful UV lamps.
- the overall efficiency of the disinfection system is essentially determined by the homogeneity of the radiation field. Because a local increase in the radiation intensity is usually not harmful, but a locally reduced intensity, which can lead to inadequate treatment. Therefore, as homogeneous a distribution of the radiation intensity as possible in the sense of a high disinfection efficiency is helpful.
- the demands made on the compactness of the UV radiator module on the one hand, and on the homogeneity and thus efficiency of the UV irradiation on the other hand, are therefore of opposite nature and not simply simultaneous.
- the invention has for its object to provide a suitable use of the UV radiator module.
- a first air guide zone for the supply of cooling air and one of the first air duct zone in particular fluidly separated second air duct zone for the discharge of heated cooling air are formed, wherein in a cross section through the housing perpendicular to the longitudinal axes of the low-pressure mercury lamps and seen from the bottom to the top of the jet exit window, the radiator arrangement and the air guide zones are arranged one behind the other, and wherein the first air guide zone is equipped with a supply air duct having at least one air guide for supplying cooling air to the radiator arrangement.
- the UV emitters of the emitter array are low pressure mercury lamps.
- Mercury low pressure lamps have a higher energy efficiency compared to medium pressure mercury lamps or high pressure mercury lamps. They also show a higher sterilization efficiency in the sense that the proportion of UV radiation in the wavelength range around 254 nm in the total emission spectrum is comparatively large. UV radiation in the wavelength range around 254 nm proves to be particularly effective in the sterilization.
- the housing has a supply air channel for the supply of cooling air and therefore via a connection to a cooling air source. In principle, cooling of mercury low pressure lamps is not necessary.
- the cooling switchable in the UV emitter module according to the invention proves to be beneficial in a number of respects to the solution of the abovementioned technical problem:
- the radiator arrangement in which the longitudinal axes of the low-pressure mercury lamps run in a common radiator plane, by the use and operation of mercury low-pressure lamps with comparatively high power, the radiator arrangement can be designed so that a UV irradiation intensity of at least
- 100 mW / cm 2 preferably at least 120 mW / cm 2 , is effected - measured at a distance of 48 mm from the radiator plane.
- the danger of overheating of the planar radiator arrangement exists, in particular, in the area of its center, less at the edge areas. Due to the forced cooling of the low-pressure mercury lamps by supplying cooling air, the length and width of the radiator array A comparatively homogeneous temperature profile adjustable, and thus also a locally homogeneous irradiation profile of the emitted UV radiation.
- the cooling capacity of the cooling air is therefore preferably designed so that sets a maximum temperature of less than 150 ° C, more preferably less than 120 ° C on the radiator assembly.
- the housing is closed and waterproof.
- the watertightness is at least equivalent to the degree of protection 6 of the IP code defined above, that is, it permanently withstands cleaning cycles with strong jet water.
- the housing Within the housing run at least one supply air duct for the cooling air and at least one exhaust duct for discharging the heated cooling air.
- the cooling air passes through the air guide, such as one or more openings or lines on the radiator arrangement, cools them and thereby warms. Since the housing is closed, the entire cooling air volume is defined as heated cooling air from the housing via the exhaust air duct and removed reproducibly, which is an advantageous measure with regard to hygiene requirements.
- the channels are designed for example as a hose or pipe and can be provided at the housing outlet with connection elements.
- Air is the technologically simplest and most cost-effective coolant. Naturally, other gases or liquids can also be used as coolants instead of or in addition to air.
- housing length the extent in the viewing direction defined above as “housing height”
- housing width the extent in the remaining spatial direction
- FIGS Orientation of the housing shown in the embodiment they merely serve to define the relative orientation of Components to each other and neither constitute a determination for a certain spatial orientation of the housing nor the relevant components in the intended use.
- the first air guide zone and the second air guide zone are fluidically separated from each other within the housing, so that there is no mixing of still cold cooling air and already heated cooling air in the housing.
- the first air duct for the supply of cold cooling air has a supply air duct, which in turn is equipped with at least one air guiding means for the defined supply of cold cooling air to the radiator arrangement.
- the heated cooling air passes as exhaust air via the second air guidance zone to an exhaust air duct or to a gas outlet, via which it is discharged from the housing.
- the first and second air-guiding zones run over each other over at least part of the housing length.
- the first air duct upstream of the second air duct zone in the cross section through the housing perpendicular to the longitudinal axes of the low-pressure mercury lamps and viewed in the direction from the bottom to the top, the first air duct upstream of the second air duct zone. That is, the supply air channel transporting the cooling air runs close to the radiator arrangement, so that the cooling air can be discharged from the supply air duct via the air guide means comparatively easily in the direction of the radiator arrangement.
- the lower air guide plane in which preferably runs the longitudinal axis of the supply air duct.
- the upper air guide plane in which preferably runs the longitudinal axis of an exhaust duct or a housing gas outlet.
- the said planes can be inclined to one another, but in the preferred case they run parallel to one another.
- the "superimposition" of these components contributes towards the housing height, but allows a particularly small housing width.
- the comparatively small housing width can be helpful in confined spaces and contributes to the homogeneity of the radiation in the irradiation area, especially if several UV radiator modules are arranged one behind the other in the transport direction of the substrate.
- the following embodiments of the UV lamp module are also preferred:
- the exhaust air duct central axis corresponds to the longitudinal axis of a possible exhaust air duct or the center axis of a housing gas outlet.
- the air supply zones for supply air and exhaust air do not only run one behind the other in the direction of view, but the axes of supply air duct and exhaust air duct or gas outlet also run one above the other in the housing center plane. This results in a particularly small housing width.
- the housing upper side has a curvature, specifically in cross-section through the housing perpendicular to the longitudinal axes of the low-pressure mercury lamps.
- the outwardly curved housing top facilitates the flow of liq fluid, for example, when cleaning the radiator module. This measure facilitates residue-free cleaning and helps to maintain and improve the hygiene standard.
- the effect of the curved top with respect to the residue-free cleaning of the radiator module is further enhanced when the two side walls cling to the curvature of the top and thereby include (in their imaginary extension) an angle in the range between 5 and 40 degrees with each other.
- the attachment of the jet exit window on the housing is crucial.
- mechanical measures are proposed for this, but these are complex.
- the jet outlet opening has a circumferential shoulder, with which the jet exit window is glued.
- the radiator arrangement is at least partially surrounded by a reflector on its side facing away from the beam exit window.
- the reflector extends in the direction of the housing length and the housing width between the radiator plane and the lower air channel plane; wherein it preferably completely covers the radiator arrangement. He contributes to the increase of Irradiation intensity and he improves the homogeneity of the radiation field.
- At least one of the housing side walls has a visible side provided with a marking, the marking being produced by laser engraving and subsequently the visible side being smoothed by electropolishing.
- Electropolishing removes any residues of marking production and contributes to the improvement of hygiene standards. It has been shown that the sequence of the steps in the sequence of laser engraving and electropolishing, after the electropolishing in the area of the engraving, establishes a surface with a different texture than the non-engraved surface, so that the marking remains visible.
- the marking of the visible side includes, for example, a logo, a logo or numbers.
- the above-mentioned object is achieved according to the invention in that it is used in a disinfection system for the ultraviolet irradiation of packaging material for foods or pharmaceuticals.
- the UV radiator module is preferably used in a module ensemble in which a plurality of identical UV radiator modules are arranged one after the other in the transport direction of a substrate to be irradiated.
