Abstract
Description
Die Erfindung betrifft eine Hochtemperatur-Desinfek tionsanlage zur Desinfektion von krankenhausspezifi schen Abfällen mit einem Einfülltrichter, einem Schneidwerk, einem beheizten Schneckenförderer und einer Auslaßschleuse, wie sie aus dem DE-GM 86 03 896.6 bekannt ist.The invention relates to a high temperature disinfectant system for disinfection of hospital specifi waste with a hopper, a Cutting unit, a heated screw conveyor and an outlet lock, as described in DE-GM 86 03 896.6 is known.
Diese vorbekannte Anlage hat sich durchaus bewährt, es hat sich jedoch gezeigt, daß nicht mit ausreichender Zuverlässigkeit ausgeschlossen wird, daß eine infek tiös belastete Luftströmung in der Schnecke auftritt, aufgrund der die Verweildauer der Luft für eine zuver lässige Desinfektion nicht ausreicht.This previously known system has proven itself, it has been shown, however, that with insufficient Reliability is excluded that an infectious air flow in the screw is badly contaminated, due to the dwell time of the air for a casual disinfection is not sufficient.
Der Erfindung liegt die Aufgabe zugrunde, sicherzustel len, daß das Austreten infektiös belasteter Luft zuver lässig vermieden wird. The invention has for its object to ensure len that the escape of infectiously polluted air verver is casually avoided.
Erfindungsgemäß wird diese Aufgabe durch die im kenn zeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung an.According to the invention, this object is achieved by the drawing part of claim 1 specified Features solved. The subclaims give advantageous Embodiments of the invention.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt die einzige Figur eine schema tische Ansicht der Anlage.The invention is described below with reference to a drawing explained. The only figure shows a schematic table view of the plant.
Die Vorrichtung besteht aus einem Einfülltrichter 10, der seitlich mit einer Einrichtung zur Aufnahme, zum Anheben und zum Verschwenken eines Müllbehälters verse hen ist. Unterhalb des Einfülltrichters 10 ist ein Schneidwerk 12 angeordnet, das den in dem Einfülltrich ter 10 nach unten fallenden Abfall zerkleinert.The device consists of a hopper 10 , the side with a device for receiving, lifting and pivoting a waste bin is hen. Below the hopper 10 , a cutter 12 is arranged, which crushes the ter 10 falling down in the Einfülltrich waste.
Unterhalb des Schneidwerks 12 befindet sich der Einlaß 14 des Schneckenförderers 16. Dabei kann der Einlaß 14 als Zellenradschleuse ausgebildet sein.The inlet 14 of the screw conveyor 16 is located below the cutting unit 12 . The inlet 14 can be designed as a rotary valve.
Der Schneckenförderer 16 besteht aus einer Schnecke 36 und einem von diesem umgebenen, mit einem Thermoöl, also einem thermisch belastbaren Öl, beheizten Mantel 38.The screw conveyor 16 consists of a screw 36 and a jacket 38 which is surrounded by the latter and heated with a thermal oil, that is to say a heat-resistant oil.
Der zu desinfizierende Abfall gelangt also über den Einfülltrichter 10, das Schneidwerk 12 und den Einlaß 14 in den Schneckenförderer 16. In dem Schneckenförde rer 16 wird der zerkleinerte Abfall auf eine Temperatur von etwa 140°C erhitzt und von dem Einlaß 14 zu der an dem anderen Ende angeordneten Auslaßschleuse 18 trans portiert. Dabei wird die Rotationsgeschwindigkeit der Schnecke 16 so gewählt, daß eine Verweildauer von meh reren Minuten sichergestellt ist.The waste to be disinfected thus reaches the screw conveyor 16 via the filling funnel 10 , the cutting mechanism 12 and the inlet 14 . In the screw conveyor rer 16 , the shredded waste is heated to a temperature of approximately 140 ° C. and transported from the inlet 14 to the outlet lock 18 arranged at the other end. The speed of rotation of the screw 16 is chosen so that a residence time of several minutes is ensured.
Weiter ist eine Umlufteinrichtung vorgesehen, die aus einer im Bereich des Einlasses 14 des Schneckenförde rers angesetzten Luftansaugleitung 20, einem Lufterhit zer 26, einem Wasserabscheider 34, einem Gebläse 22 und einer im Bereich der Auslaßschleuse 18 mündenden Luft einlaßleitung 24 besteht. Diese Umlufteinrichtung dient dazu, im Bereich der Auslaßschleuse 18 Luft in die Schnecke 16 einzublasen, die sodann gegen die (in der Zeichnung von links nach rechts verlaufende) Förder richtung des zu desinfizierenden Abfalls von der Aus laßschleuse 18 zu dem Einlaß 14 strömt und dort wieder von der Luftansaugleitung 20 eingesaugt wird. Der Luft erhitzer 26 stellt dabei sicher, daß die im Bereich des Einlasses 14 des Schneckenförderers 16 angesaugte, noch infektiös belastete Luft desinfiziert wird, bevor sie wieder im Bereich der Auslaßschleuse 18 eingeblasen wird, so daß ein Austritt infektiös belasteter Luft aus der Auslaßschleuse 18 ausgeschlossen ist.Furthermore, a recirculation device is provided, which consists of an air intake line 20 attached in the area of the inlet 14 of the screw conveyor, an air heater 26 , a water separator 34 , a blower 22 and an air inlet line 24 opening in the area of the outlet lock 18 . This air recirculation device serves to blow air into the screw 16 in the area of the outlet lock 18 , which then flows against the (in the drawing from left to right) conveying direction of the waste to be disinfected from the lock lock 18 to the inlet 14 and flows there again is sucked in by the air intake line 20 . The air heater 26 ensures that the air sucked in the area of the inlet 14 of the screw conveyor 16 , which is still infectiously contaminated, is disinfected before it is blown in again in the area of the outlet lock 18 , so that an escape of infectiously contaminated air from the outlet lock 18 is excluded is.
Die von der Umlufteinrichtung bewegte, gegen die För derrichtung des zu desinfizierenden Abfalls bewegte Luft trägt zur Desinfektion der Abfälle in der Schnecke bei, insbesondere verhindert sie aber, daß eine dem zu desinfizierenden Abfall voreilende Luftströmung von dem Einlaß 14 zu der Auslaßschleuse 18 auftreten kann.The air moved by the air recirculation device, against the direction of the waste to be disinfected, contributes to the disinfection of the waste in the screw, but in particular it prevents that an air flow leading to the waste to be disinfected can occur from the inlet 14 to the outlet lock 18 .
Der dem Lufterhitzer nachgeschaltete Wasserabscheider 34 bewirkt, daß die Umluft getrocknet wird. Auf diese Weise kann der Feuchtigkeitsgehalt des desinfizierten Abfalls vermindert werden.The water separator 34 connected downstream of the air heater causes the circulating air to be dried. In this way, the moisture content of the disinfected waste can be reduced.
Weiter ist eine weitere Luftansaugleitung 28 versehen, die an den Einzeltrichter 10 angesetzt ist und in die erste Luftansaugleitung 20 mündet, wobei die erste Ansaugleitung 20 und die weitere Ansaugleitung 28 mit regelbaren Schiebern 30, 32 versehen sind. Eine solche Ausgestaltung ermöglicht es, bei Sperren der ersten Ansaugleitung 20 einen Strom erhitzter Luft durch die gesamte Anlage, insbesondere also auch durch das Schneidwerk 12 zu führen, um dieses - etwa zum Zwecke der Reparatur nach Leerlaufen der Anlage - zu desinfi zieren. Auch dadurch wird dem Austreten von nicht desinfizierter Luft aus der Anlage entgegengewirkt. Die weitere Luftansaugleitung 28 kann aber auch dazu verwendet werden, in dem Einfülltrichter 10 einen Un terdruck zu erzeugen, der einem Austreten von infektiös belasteter Luft bei dem Einschütten des Abfalls entge genwirkt.Next, a further air suction pipe 28 is provided which is attached to the single hopper 10 and opens into the first air intake pipe 20, the first suction duct 20 and the additional suction line are provided with controllable valves 30, 32 28th Such a configuration makes it possible to result in locking of the first suction duct 20 a flow of heated air through the entire system, thus in particular through the cutter 12 to this - for example for the purpose of repair after emptying of the system - to disinfect decorate. This also counteracts the escape of non-disinfected air from the system. The further air intake line 28 can also be used to generate a vacuum in the hopper 10 , which counteracts the escape of infectiously contaminated air when pouring the waste.
