Description

Nr. 391 934No. 391 934

Die Erfindung bezieht sich auf ein Entkeimungsgerät für Luftkanäle, Rohre u. dgl., bestehend aus einem Gebläse mit Schalldämpfern und einem damit in Serie liegenden Lufterhitzer sowie UV-Strahler.The invention relates to a sterilization device for air ducts, pipes and. Like., consisting of a blower with silencers and a serial air heater and UV lamp.

In allen Anstalten, wo höchste hygienische Ansprüche an Räume, Apparate und Personen gestellt werden, können Luftkanäle, Rohre u. dgl. bisher nur schwer und unzureichend entkeimt werden. 5 Ziel der Erfindung ist die Schaffung eines Gerätes, mit welchem auch diese Luftkanäle, Rohre u. dgl. in einwandfreier Weise entkeimt werden können. Dies wird bei dem eingangs näher bezeichneten Entkeimungsgerät erfindungsgemäß dadurch erreicht, daß dem Lufterhitzer über ein Umschaltventil ein an sich bekanntes Schwebstoff-Filter mit einer an sich bekannten parallel dazu angeordneten Bypaß-Leitung nachgeschaltet ist, welcher Parallelanordnung ein Ultraschall-Vernebler zur Vernebelung eines Entkeimungsmittels auf eine 10 Teilchengröße bis zu 0,3 pm nachgeschaltet ist.In all institutions where the highest hygienic demands are placed on rooms, apparatus and people, air ducts, pipes and the like can be used. The like. So far, only with difficulty and inadequate sterilization. 5 The aim of the invention is to provide a device with which these air channels, pipes and. Like. Can be sterilized in a flawless manner. This is achieved according to the invention in the disinfection device specified at the outset in that the air heater is connected via a changeover valve to a suspended particle filter known per se with a known bypass line arranged parallel thereto, which parallel arrangement is an ultrasonic nebulizer for nebulizing a disinfectant a 10 particle size up to 0.3 pm is connected downstream.

Durch diese Merkmalskombination ergibt sich der Vorteil, daß die Luft in mit Entkeimungsmittel übersättigtem Zustand nur die Luftkanalinnenwände benetzt und durchströmt, so daß eine einwandfreie Entkeimung dieser ansonsten kaum zugänglichen Stellen gegeben ist.This combination of features results in the advantage that the air, in the state saturated with disinfectant, only wets and flows through the inner walls of the air duct, so that these otherwise hardly accessible places are properly disinfected.

Aus der DE-PS 7 139 ist ein Luft-Emeuerungs- und -Verbesserungs-Apparat bekannt, bei welchem die Luft 15 über mit Wasser, das mit wohlriechenden, desodorierenden, desinfizierenden Zugaben versetzt ist, gefüllte Behälter geführt wird, worauf diese - eventuell nachgewärmte - Luft dann in die Räume ventiliert wird.From DE-PS 7 139 an air renewal and improvement apparatus is known, in which the air 15 is passed over containers filled with fragrant, deodorant, disinfectant additions of water, whereupon these - possibly reheated - Air is then ventilated into the rooms.

Aus der US-PS 2 876 507 ist ein Verfahren zum Desodorieren und Sterilisieren der Raumluft bekannt, bei welchem die Luft über einen Luftwäscher mit Düsenzerstäuber geführt wird um dabei die Luft zu reinigen und mit Zusätzen zu desodorieren bzw. zu sterilisieren. Damit dabei die Luftfeuchtigkeit in den Räumen nicht zu hoch 20 ansteigt (und kontrolliert werden kann), wird als Regulator der Luftfeuchte Li Cl-Salz der Wasser/ Desodorierlösung beigemischt, so daß durch Änderung des Dampfdruckes die Feuchtigkeitsaufhahme der den Luftwäscher durchströmenden Luft geregelt wird.From US Pat. No. 2,876,507 a method for deodorising and sterilizing the room air is known, in which the air is passed over an air washer with a nozzle atomizer in order to clean the air and to deodorize or sterilize it with additives. So that the air humidity in the rooms does not rise too high (and can be checked), Li Cl salt is added to the water / deodorising solution as a regulator, so that the moisture absorption of the air flowing through the air washer is regulated by changing the vapor pressure.

Auch aus der FR-PS 772 862 und der GB-PS 1 400 519 ist die Konditionierung von Raumluft durch Erwärmung und/oder Filterung, gegebenenfalls Kühlung und UV-Strahlung bekannt. 25 Weiters ist die Entkeimung der Raumluft durch UV-Strahlung aus der AT-PS 183 929, der DE-PS 970 365 und der CH-PS 445 782 bekannt.From FR-PS 772 862 and GB-PS 1 400 519 the conditioning of room air by heating and / or filtering, optionally cooling and UV radiation is known. 25 Furthermore, the disinfection of room air by UV radiation is known from AT-PS 183 929, DE-PS 970 365 and CH-PS 445 782.

Während somit bei diesen bekannten Einrichtungen die Raumluft selbst behandelt wird, ist es demgegenüber das Ziel des erfindungsgemäßen Entkeimungsgerätes, die Entkeimung an den Luftkanalinnenwänden (samt Klappen, Gitter und Einbauten) vorzunehmen. Dies wird mit dem erfindungsgemäßen Gerät so erreicht, daß die 30 mittels des Ultraschall-Verneblers vernebelte, nicht gesundheitsgefährdende Entkeimungsflüssigkeit die Kanalinnenwände erreicht und nach entsprechender Einwirkungsdauer die dort vorhandenen Keime äbtöteLIn contrast, while the ambient air itself is treated in these known devices, the aim of the disinfection device according to the invention is to carry out the disinfection on the air duct inner walls (including flaps, grilles and fittings). This is achieved with the device according to the invention in such a way that the disinfectant liquid which is atomized by means of the ultrasonic nebulizer and does not pose a health hazard reaches the inner walls of the channel and, after a corresponding period of action, kills the germs present there

Gemäß einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, daß im Wege des Eingangsanschlusses ein an sich bekanntes Überdruckventil vorgesehen ist Dadurch wird im zu entkeimenden Luftkanal ein Überdruck aufgebaut, so daß die mit Entkeimungsmittel übersättigte Luft auch an undichte Stellen 35 gelangt.According to a further embodiment of the invention, it can be provided that a pressure relief valve known per se is provided in the way of the inlet connection. As a result, an excess pressure is built up in the air duct to be sterilized, so that the air oversaturated with disinfectant also reaches leaks 35.

Die Erfindung wird nun an Hand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben.The invention will now be described with reference to an embodiment shown in the drawing.

Bei dem dargestellten Entkeimungsgerät (1) wird das nichtgesundheitsgefährdende Entkeimungsmittel durch einen Ultraschall-Vernebler (8) in kleinste Aerosole bis 0,3 pm vernebelt und mittels eines Gebläses (3) an die 40 zu entkeimenden Stellen geführt. Das feinst vernebelte Entkeimungsmittel bestreicht die zu entkeimenden Oberflächen (13) und kondensiert, da die Oberflächentemperatur der Kanäle, Rohre u. dgl. unter dem Taupunkt des Luft-Entkeimungsmittelgemisches liegt. Dies wird dadurch erreicht, daß die vom Gebläse (3) angesaugte Luft durch den Lufterhitzer (5) stufenlos - auf ca. 35°C - erwärmt wird und daher wesentlich mehr Feuchtigkeit aufnehmen kann als normale Raumluft. Das Luft-Entkeimungsmittelgemisch wird über flexible Rohre bzw. 45 Schläuche (11) an den Luftkanal (13) geführt, welche Rohre (11) am Kanalanschlußstück (12) befestigt sind. Während des Entkeimungsvorganges wird das einen UV-Strahler enthaltende Schwebstoff-Filter (7) mit einer Bypaß-Leitung (18) durch entsprechende Schaltung des Umschaltventils (6) umgangen. Die zu entkeimenden Kanalsektionen (13) sind mit entsprechenden Absperrvorrichtungen (19), (20) (Klappe, Deckel u. dgl.) auszurüsten. Am Kanalanschluß-Austritt (14) wird ein einstellbares Überdruckventil (15) eingesetzt, so daß das 50 in den Kanal (13) geblasene Luft-Entkeimungsmittelgemisch unter Überdruck steht und dadurch auch undichte Stellen im Kanalsystem entkeimt werden (eventuell gesichtet und dann gedichtet werden können). Über das Überdruckventil (15) wird das Luft-Entkeimungsmittelgemisch durch flexible Leitungen bzw. Schläuche (16) über den Anschluß (21) dem Entkeimungsgerät (1) zugeführt und weiter mit dem Entkeimungsmittel im Ultraschall-Vernebler (8) angereichert und so lange im Kreislauf gehalten, bis die erforderliche Konzentration (je 55 nach Entkeimungsmittel und Vorschrift der Hersteller) im Kanal (13) erreicht ist. Nach der vorgeschriebenen Einwirkungszeit wird die Luft im Kreislauf durch den Lufterhitzer (5) auf ca. 70°C erhitzt, so daß der Kanal (13) austrocknet. Anschließend wird der flexible Ansaugschlauch (16) vom Entkeimungsgerät (1) abgenommen und am Kanalanschlußstück (17) eines Fortluftsystems (17), (22) angeschlossen und das Schwebstoff-Filter (7) zugeschaltet. Dann wird die in der Kanalsektion (13) befindliche Entkeimungsluft über den Fortluftkanal (22) 60 ins Freie geblasen.In the disinfection device (1) shown, the disinfectant which is not hazardous to health is atomized into the smallest aerosols up to 0.3 pm by an ultrasonic nebulizer (8) and guided to the 40 points to be disinfected by means of a blower (3). The finely nebulized disinfectant brushes the surfaces to be sterilized (13) and condenses, since the surface temperature of the channels, pipes and the like. Like. Is below the dew point of the air-disinfectant mixture. This is achieved in that the air drawn in by the blower (3) is continuously heated by the air heater (5) - to approx. 35 ° C - and can therefore absorb considerably more moisture than normal room air. The air-disinfectant mixture is fed to the air duct (13) via flexible pipes or 45 hoses (11), which pipes (11) are attached to the duct connection piece (12). During the sterilization process, the suspended matter filter (7) containing a UV lamp is bypassed with a bypass line (18) by switching the changeover valve (6) accordingly. The channel sections (13) to be sterilized are to be equipped with appropriate shut-off devices (19), (20) (flap, cover and the like). An adjustable pressure relief valve (15) is used at the duct connection outlet (14), so that the 50 air / disinfectant mixture blown into the duct (13) is under overpressure and thus leaks in the duct system can also be sterilized (possibly sighted and then sealed) ). Via the pressure relief valve (15), the air-disinfectant mixture is fed through flexible lines or hoses (16) via the connection (21) to the disinfection device (1) and further enriched with the disinfectant in the ultrasonic nebulizer (8) and so long in the circuit held until the required concentration (55 depending on the disinfectant and manufacturer's instructions) in the channel (13) is reached. After the prescribed exposure time, the air in the circuit is heated to approx. 70 ° C. by the air heater (5), so that the channel (13) dries out. The flexible suction hose (16) is then removed from the sterilization device (1) and connected to the duct connection piece (17) of an exhaust air system (17), (22) and the suspended matter filter (7) is switched on. Then the sterilizing air in the duct section (13) is blown into the open via the exhaust air duct (22) 60.

Schläuche (11), (16) wird insbesondere bei mobilen Entkeimungsgeräten eine universellere Anwendbarkeit erzielt; es ist dann vor allem der Abstand, der am zu -2-Through the use of flexible pipes or hoses (11), (16), more universal applicability is achieved, particularly in the case of mobile sterilization devices; then it is above all the distance that is at -2-
