Abstract

A gas or liquid flowing through a tube(8) is sterilised by UV light from parallel tubes(7). The tubes(7) and reflectors(6) are mounted in the upper and lower halves(1) of a housing. The housing halves, together with the light tubes and reflectors, are removable without disturbing the flow of gas/liquid. The housing halves are mounted on the housing end pieces on the supply tube(8). The light tubes(7) are mounted on the reflectors(6). Indicating lights are provided on the housing to show which light tubes are inoperative, since the housing is closed to prevent the emission of damaging radiation.

Description

Vorrichtung zum Ent zum Entkeimen von Flüssigkeiten und GasenDevice for disinfecting liquids and gases

mittels Ultraviolettlichts.by means of ultraviolet light.

Es sind Ultraviolett-Entkeimungsgeräte für strömende Flüssigkeiter oder Gase bekannt, die gekernzeichnet sind durch die achspqrailele und konzertrische Arordrur; einer Anzahl von Uitraviolett-Prernerröhrer um ein vor dem zu entkeimenden Medium durchströmtes Rohr aus UV-Strahlen-durchlässigem Material, beispielsweise Quarzglas. Diese Geräte besitzen ein zylindrisches oder kastenförmiges Außengehäuse und ir deren Irnerem geeiete Reflektoren, welche die Ultraviolettstrahlung gegen das vom Medium durchströmte Rohr reflektieren und so eine optimale, konzentrierte Pestrahlung des Mediums eriführe sollen.They are ultraviolet disinfection devices for flowing liquids or gases known, which are characterized by the achspqrailele and konzertrische Arordrur; a number of Uitraviolet Prerner tubes around one in front of the one to be sterilized Medium flowed through pipe made of UV-radiation-permeable material, for example Quartz glass. These devices have a cylindrical or box-shaped outer housing and internal reflectors which counter ultraviolet radiation reflect the pipe through which the medium flows and thus an optimal, concentrated Should experience irradiation of the medium.

Ein Nachteil der bisher bekannten Ultraviolett-Entkeimungsgeräte hier genannte Zwecke besteht in dem schwierigen Auswechseln der Ultraviolett-Brennerröhren bei Ausfall einer oder mehrerer davon. Bekannte Konstruktionen machen es nämlich erforderlich, den turchflußbetrieb zu stoppen, das Gerät herauszllirstallieren, um die Röhren aus ihrer Passungen zu lösen, ja vorher das Gerät in seine Einzelteile zu zerlegen. Für die Reinstallation muß in gleicher weise rückwärts verfahren werden.A disadvantage of the previously known ultraviolet disinfection devices here said purposes is the difficult replacement of the ultraviolet burner tubes if one or more of them fail. Well-known constructions do it necessary to stop the flow operation, dismantle the device, in order to loosen the tubes from their fits, yes, beforehand the device into its individual parts disassemble. For reinstallation you have to move backwards in the same way.

Eine solche Ultraviolett-Brennerröhre hat zwar eine durchschrittliche Lebensdauer vor einigen Tausen Betriebsstunden, aber es kommt vor, daß hier und da eine solche schon nach relativ kurzer Betriebazeit ausfällt.Such an ultraviolet burner tube has a step-through one Lifespan a few thousand hours ago, but it happens that here and as such fails after a relatively short period of operation.

Die dann anfallenden Kosten mit beispielsweise Anfahrt eines Spezialisten stehen in einem äußerst ungünstigen Verhältnis zu den Kosten einer neuen Rrennerröhre. In der Verkaufspraxis haben sich iese vorhersehbar hohen Kosten für das Auswechseln der Prerrerröhren abschreckend gegen die Anschaffung eines derartigen Geräts erwiesen.The costs then incurred with, for example, the arrival of a specialist are in an extremely unfavorable relationship to the cost of a new racing tube. In sales practice, these have foreseeably high costs for replacement of the Prerrerröhren turned out to be a deterrent against the purchase of such a device.

Gegenstand der vorlien Erfindung ist daher die Konstruktion eirips Ultraviolett-Entkeimungsgeräts beschrieberer Art in mehr service-freundlicher Weise und derart, daß jeder Betreiber eines solchen mit Heimwerkerfähigkeriten den Austausch der Brennerröhren selbst vornehmen kann, ohne dabei den Durchlaufbetrieb des strömenden Mediums, beispielsweise den Filterbetrieb bei Schwimmbädern, stoppen, Dichtungen neu anlegen zu müssen, usw. Er braucht nur eine neue Brennerrohre zu kaufen (Vergleich: Langfeldröhre), um dann den Austausch selbst vorzunehmen.The subject of the present invention is therefore the construction eirips Ultraviolet disinfection device of the type described in a more service-friendly manner and in such a way that every operator of one with a do-it-yourselfer can exchange the burner tubes can make themselves without losing the continuous operation of the flowing Medium, for example the filter operation in swimming pools, stop seals having to rebuild, etc. He only needs to buy a new burner tube (comparison: Long-wave tube), in order to then carry out the exchange yourself.

Anhang der Zeichnung wird verdeutlicht, wie das vor sich geben kann: Figur 1 ist eine perspektivische Darstellung des Geräts von uen, Man sieht das in zwei Halbschalen zerfallende Gehäuse 1 mit seinen Kopfstücken 2 und den sie zusammenhaltenden Schrauben 3. Sodann sieht man die Muffen- oder Schraubverbindungen 4, mit denen das Gerät in ein Leitungssystem 5, beispielsweise einen Filterkreislauf, eingefügt und dicht verbunden ist.The appendix of the drawing shows how this can appear: Figure 1 is a perspective view of the device, seen in FIG two half-shells disintegrating housing 1 with its head pieces 2 and those holding them together Screws 3. Then you can see the socket or screw connections 4 with which the device is inserted into a line system 5, for example a filter circuit and is tightly connected.

Figur 2 zeigt einen Querschrnitt durch das erfindungsgemäße Gerët entlang der Linie A - A in Figur 1. Man sieht die GeFauseschalen 1, die Reflektoren 6, die nur eine im Gehäuse 1 eirsitzende Befestigung haten, und die Strahlerröhren 7, hier beispielsweise 6 Stück, die an ihren Enden mit geeigneter Passungen 10 montiert sind, sowie das von dem zu entkeimenfen Medium durchströmte Rohr 8.Figure 2 shows a cross section through the device according to the invention along the line A - A in Figure 1. You can see the GeFauseschalen 1, the reflectors 6, which had only one fastening that was seated in the housing 1, and the radiator tubes 7, here for example 6 pieces, which are mounted with suitable fits 10 at their ends are, as well as that of which to sterilize Medium flowing through the pipe 8th.

Figur 3 zeigt perspektivisch den Zustand des in dem LeitMlngssystem 5 installierten Geräts, von dem jetzt nur noch die Verbindungen 4, die Gehäuse-Kopfstticke 2 und das Rohr 8 zu sehen sind. Die Gehäuseteile 1 und die Reflektoren 6 mit den UV-Brennerröhren 7 wurden nach Lösen der Schrauben 3 angenommen und stehen jetzt, getrennt von den in Figur 3 oezeitter Teilen, fUr Arbeiten, wie Auswechseln der Röhren etc., zur Verfügung. Es ist eirleuchtend, daß nicht nur das Wechseln der Brennerröhren, sondern auch andere Arbeiten wie das Auswechseln von außen am Gehause angeordneten Kor.-trolleuchten 11 sowie die Beseitigung anderer, beispielsweise elektrischer Fehler leicht erfolgen können.FIG. 3 shows in perspective the state of the control system in the control system 5 installed device, of which now only the connections 4, the housing headsticks 2 and the pipe 8 can be seen. The housing parts 1 and the reflectors 6 with the UV burner tubes 7 were accepted after loosening the screws 3 and are now separate from the parts shown in FIG. 3, for work such as replacing the Tubes etc. are available. It is obvious that not just changing the Burner tubes, but also other work such as replacing the outside of the housing arranged Kor.-Trolleuchten 11 as well as the elimination of others, for example electrical faults can easily occur.

Figur 4 zeigt den demontierten oberen Reflektorteil 6 mit den 3 daran montierten Ultravi.olett-Brennerröhren7und ihren Fassungen 10 in ihrem für Arbeiten daran offenen Zustand.FIG. 4 shows the dismantled upper reflector part 6 with the 3 on it mounted Ultravi.olett burner tubes 7 and their sockets 10 in their for work at it open state.

Man sieht, wie leicht jetzt die Röhren vor allem für lediglich einen Austausch zugänglich sind.You can see how easy the tubes are now, especially for just one Exchanges are accessible.

Die Rontrolleuchten 11 können vorgesehen werden, um vor außen an dem Ja wegen der für den Menschen schädlichen Strahlung gänzlich geschlossenen Gehäuse erkennbar zu machen, ob eine oder mehrere und welche Strahlerröhren ausgefallen sind.The control lights 11 can be provided to the outside of the Yes, because of the completely closed housing, which is harmful to humans to make it clear whether one or more and which tube has failed are.
