mit Atemgaswith breathing gas
Die Erfindung betrifft ein Verfahren zum Pullen von Druckgasflaschen mit Atemgasen und eine Vorrichtung dazu.The invention relates to a method for pulling pressurized gas cylinders with breathing gases and a device to do so.
Das für'den Träger von Atemschutzgeräten bei der Benutzung benötigte Atemgas wird in Vorratsbehältern, den Druckgasflaschen, mitgeführt. Das Füllen bzw. Wiederfüllen der Druckgasflaschen erfolgt auf unterschiedliche Weise, beispielsweise durch Überströmen aus Hochdruckbehältern oder mittels Umfüllpumpe aus Vorratsbehältern oder mittels Hochdruckkompressoren. This is for the wearer of respiratory protective equipment when using it The breathing gas required is carried in storage containers, the pressurized gas cylinders. The filling or refilling of the Pressurized gas cylinders are made in different ways, for example by overflowing from high-pressure containers or by means of a transfer pump from storage containers or by means of high pressure compressors.
An die Reinheit von Atemgasen sind besondere AnforderungenThere are special requirements for the purity of breathing gases

gestellt. Die Atemgase müssen frei sein von gesundheitsschädlichen Bestandteilen, darüber hinaus sollen sie geschmacksfrei und geruchlos sein. Wasser soll nicht in den Druckgasflascheri enthalten sein, da es zu Korrosionen und nach entsprechender Zeit zu Undichtigkeiten führt. Ein hoher Feuchtigkeitsgehalt der Druckluft kann u.U. für den Gerätträger lebensgefährlich sein, da die Abkühlung bei der Expansion des Druckgases zur Kondensation und Eisbildung in den Gaswegen führen kann, die dadurch verengt oder sogar verstopft werden. Obgleich die Atemgas erzeugenden bzw. umfüllenden Anlagen mit speziellen Einrichtungen, wie z.B. Staub- und Gasfilter, öl- und Wasserabscheider, ölgeruchsfilter und Gastrockner ausgerüstet sind, treten dennoch Verschmutzungen und Wasser im FIascheninnern auf. Sauberes und trockenes Atemgas ist nur dann wirklich zu erreichen, wenn jede Druckgasflasche vor dem Einfüllen des Atemgases kontrolliert wird. In der Praxis ist dies"kaum durchführbar, da dafür das Flaschenventil abgeschraubt werden müßte. Eine Ausspülung der Druckgasflasche■ unmittelbar vor dem Füllen mit dem einzufüllenden Atemgas beseitigt die Nachteile nicht, denn das flüssige Wasser wird dabei nicht entfernt.posed. The breathing gases must be free from harmful ones Ingredients, in addition, they should be tasteless and odorless. Water shouldn't be in the Compressed gas bottles must be included, as it leads to corrosion and, after a certain time, to leaks. A high moisture content in the compressed air can under certain circumstances be life-threatening for the device wearer, as it cools down During the expansion of the compressed gas, it can lead to condensation and ice formation in the gas paths, which narrows as a result or even become clogged. Although the breathing gas generating or transferring systems with special devices, such as dust and gas filters, oil and water separators, oil odor filters and gas dryers there will still be dirt and water inside the bottle on. Clean and dry breathing gas can only really be achieved if every pressurized gas cylinder is available the filling of the breathing gas is checked. In practice this is "hardly feasible because the cylinder valve is used for it would have to be unscrewed. Rinsing out the compressed gas cylinder immediately before filling with The breathing gas to be filled does not eliminate the disadvantages, because the liquid water is not removed in the process.
Der Erfindung liegt die Aufgabe zugrunde, die geschilderten Nachteile zu vermeiden und eine einfache VorrichtungThe invention is based on the object of avoiding the disadvantages described and a simple device

zu schaffen, mit deren Hilfe die Druckgasflaschen einwandfrei und wirtschaftlich gereinigt werden können. Das erfindungsgemäße Verfahren besteht darin, daß die Druckgasflasche vor dem Füllen mit Atemgas erwärmt und evakuiert wird. Dadurch wird mit Sicherheit erreicht, daß die Druckgasflasche von Fremdgasen und Wasser sowohl in flüssiger als auch in Dampfform befreit wird. Das anschließend eingefüllte, in den Erzeugungsanlagen bzw. Umfüllanlagen durch die dort vorhandenen Einrichtungen gereinigte Atemgas wird durch die Flasche nicht wieder verschmutzt. Der Benutzer erhält sauberes Atemgas. Das erfindungsgemäße Verfahren kann mit einer Zwangssteuerung versehen sein, so daß dem Füllpersonal eine Umgehung des ReinigungsVorganges, sei es unter Zeitdruck oder auch nur aus Bequemlichkeit, unmöglich gemacht wird.to create, with the help of which the pressurized gas cylinders can be cleaned properly and economically. The method according to the invention consists in that the compressed gas cylinder is heated and with breathing gas before it is filled is evacuated. This ensures that the compressed gas cylinder is protected from both foreign gases and water is released in liquid as well as in vapor form. The subsequently filled in, in the generating plants respiratory gas that has been cleaned by the facilities available there is not released through the bottle dirty again. The user receives clean breathing gas. The inventive method can with a Forced control be provided so that the filling staff can bypass the cleaning process, be it under time pressure or even just for convenience, is made impossible.
Die Erfindung betrifft weiterhin eine Vorrichtung zur Durchführung des Verfahrens, die aus einer Heizeinrichtung für die in diese einsetzbare Druckgasflasche und aus einem Flaschenanschlußstück mit Dreiwegeventil besteht, dessen einer Zweig mit einer Vakuumpumpe verbunden und dessen anderer Zweig an die Fülleinrichtung angeschlossen ist.The invention further relates to a device for carrying out the method, which consists of a heating device for the pressurized gas cylinder that can be inserted into this and consists of a cylinder connection piece with a three-way valve, one branch of which is connected to a vacuum pump and the other branch is connected to the filling device is.
Gemäß einer weiteren Ausbildung der Vorrichtung kann inAccording to a further embodiment of the device, in

Bei dieser Vorrichtung ist die Druckgasflasche bei eingeschaltetem Heizschalter über ein Dreiwegeventil mit einer Vakuumpumpe verbunden und bei abgeschaltetem Heizschalter über das Dreiwegeventil an die Fülleinrichtung angeschlossen ist. Vorteilhaft kann die Vorrichtung konstruktiv eine Einheit darstellen. Sie entspricht damit, wie das Verfahren selbst, der Aufgabe, Reinigungsvorgang und Füllvorrichtung untrennbar zusammenzufassen.the power supply line for the heating device can be arranged a switch that connects to the three-way valve is coupled. With this device, the pressurized gas cylinder is over when the heating switch is on a three-way valve is connected to a vacuum pump and when the heating switch is switched off via the three-way valve is connected to the filling device. The device can advantageously be constructed as a unit. Like the process itself, it is inseparable from the task, cleaning process and filling device summarize.
Gemäß einer weiteren Ausbildung der Erfindung kann im Interesse des ungestörten Ablaufes des Verfahrens, und damit für die Sicherheit des Gerätträgers, die Heizschalterstellung "ein" mit Evakuieren und Austrocknen und das Füllen in der Heizschalterstellung "aus" von einem Programmschaltwerk gesteuert sein.According to a further embodiment of the invention, in the interest of the undisturbed process of the method, and So for the safety of the equipment wearer, the heating switch position "on" with evacuation and drying out and the filling can be controlled by a program switch when the heating switch is in the "off" position.
Die Anwendung des Füllverfahrens nach der Erfindung ermöglicht das Füllen von Atemgasflaschen, in denen, weil sie zuverlässig einem Reinigungsvorgang unterworfen wurden, das vorschriftsmäßig vorbereitete und trockene Atemgas seine Qualität behält.The use of the filling method according to the invention enables the filling of breathing gas cylinders in which, because they have been reliably subjected to a cleaning process that has been properly prepared and dry Breathing gas retains its quality.
