Description

Es ist bereits bekannt, das Entweichen von Dämpfen aus lagernden Flüssigkeiten, z. B. Petroleum od. dgl., dadurch zu verhindern, daß man auf den Flüssigkeiten liegende Schwimmer vorsieht, die annähernd gegenüber dem Umfang des Flüssigkeitsbehälters abdichten.It is already known that vapors escape from stored liquids, z. B. Petroleum od. Like. To prevent that one is lying on the liquids Provides float, which is approximately opposite the circumference of the liquid container seal.

Diese Abdichtung ist nicht in jeder Beziehung einwandfrei und braucht das auch nicht zu sein, wenn es sich um solche Flüssigkeiten handelt, deren Dämpfe leichter sind als Luft. Die in geringem Ausmaß entweichenden Dämpfe steigen im Gefäß nach oben und treten selbsttätig durch vorgesehene Öffnungen aus.This seal is not and needs to be perfect in every respect Not to be that either when it comes to liquids and their vapors are lighter than air. The small amount of escaping vapors rise in the vessel to the top and exit automatically through the openings provided.

Anders verhält sich dies jedoch bei Dämpfen, die schwerer sind als Luft, wie bei Chlordioxyd, das inUsung ungefährlich, in Form vonDampf jedoch hoch explosiv ist. Die in geringem Ausmaß zufolge der ungenügenden Abdichtung des Schwimmers entweichenden Dämpfe bleiben zufolge ihres gegenüber der Luft höheren spezifischen Gewichts unmittelbar über dem Schwimmer stehen und entweichen nicht selbständig durch eine im Lagerbehälter vorgesehene Öffnung.However, this is different for vapors that are heavier than Air, as with chlorine dioxide, is harmless in solution, but high in the form of vapor is explosive. To a small extent, due to the inadequate sealing of the float escaping vapors remain due to their higher specific properties compared to air Weight stand directly above the swimmer and do not escape independently through an opening provided in the storage container.

Gemäß der Erfindung wird infolgedessen, trotzdem ein Schwimmer vorgesehen ist, unmittelbar über dem Niveau der Lösung, d. h. über dem Schwimmer, Luft zugeführt und diese zusammen mit dem Chlordioxyddampf im oberen Bereich des Gefäßes entnommen. Da jedoch das Niveau der Chlordioxydlösung schwankt, wird man zweckmäßig die Lage des Lufteintritts in Abhängigkeit von der Lage des Schwimmers regeln. Der Schwimmer kann hierbei ein axial verschiebbares Rohr steuern, derart, daß die untere Ausmündung des Rohres stets unmittelbar über dem Schwimmer liegt. Zweckmäßig ist dabei dieses Rohr durch den Schwimmer selbst getragen und besitzt im Bereich der Einmündung in den Schwimmer Öffnungen.As a result, according to the invention, a float is nevertheless provided is, just above the level of the solution, d. H. above the float, air supplied and this is taken together with the chlorine dioxide vapor in the upper area of the vessel. However, since the level of the chlorine dioxide solution fluctuates, the location is appropriate regulate the air inlet depending on the position of the float. The swimmer can control an axially displaceable tube in such a way that the lower mouth of the pipe is always directly above the float. This is useful Tube carried by the swimmer himself and has in the area of the confluence in the float openings.

Die Zeichnung zeigt eine Ausführungsform einer erfindungsgemäßen Neuerung im Axialschnitt. Ein Gefäß i, das zur Lagerung oder Aufspeicherung von Chlordioxyd bestimmt ist, besitzt einen Zufluß 2 und einen Abfluß 3. Der Deckel 4 ist mit einem Rohrstutzen 5 versehen, der zum Anschluß an einen Unterdruckförderer bestimmt ist.The drawing shows an embodiment of an innovation according to the invention in axial section. A vessel i, which is used to store or accumulate chlorine dioxide is determined, has an inlet 2 and an outlet 3. The lid 4 is with a Pipe socket 5 provided, which is intended for connection to a vacuum conveyor.

Auf der im Gefäß i ruhenden Chlordioxydlösung 6 liegt ein Schwimmer 7, der durch einen Hohlkörper aus Kunstharz, z. B. Polyvinylchlorid, gebildet ist. Der Schwimmer 7 ist verbunden mit einem Rohr 8, das den Deckel 4 in einer Führung 9 durchsetzt. Die Einmündung des Rohres 8 in den Schwimmer 7 ist mit radialen Lochungen io versehen.A float rests on the chlorine dioxide solution 6 resting in the vessel i 7, which is through a hollow body made of synthetic resin, for. B. polyvinyl chloride is formed. The float 7 is connected to a tube 8 which holds the cover 4 in a guide 9 interspersed. The confluence of the tube 8 in the float 7 has radial perforations io provided.

Der Schwimmer 7, dessen Umfang dem Querschnitt des Gefäßes i abzüglich des für seine axiale Bewegung erforderlichen Spiels entspricht, verhindert im großen und ganzen einen Austritt von Chlordioxyddämpfen in den Leerraum i i des Gefäßes. Sofern geringe Mengen von Chlordioxyd trotzdem austreten, werden diese dadurch beseitigt, daß an den Stutzen 5 ein Sauganschluß geschaltet ist, der aus dem Leerraum i i Luft entnimmt, die durch das Rohr 8 nachzieht. Da die Öffnungen io unmittelbar über dem Schwimmer 7, d. h. unmittelbar über dem Lösungsspiegel liegen und Chlordioxyddämpfe schwerer sind als Luft, so werden in erster Linie Chlordioxyddämpfe auf diesem Wege entnommen und eine Explosionsgefahr besteht nicht.The float 7, the circumference of which is subtracted from the cross section of the vessel i corresponds to the game required for its axial movement, prevented in large and the whole of an escape of chlorine dioxide vapors into the empty space i i of the vessel. If small amounts of chlorine dioxide escape anyway, they will be eliminated. that a suction connection is connected to the nozzle 5, which from the empty space i i air removes, which pulls through the pipe 8. Since the openings io immediately above the Float 7, d. H. directly above the solution level and chlorine dioxide vapors are heavier than air, chlorine dioxide vapors are primarily produced in this way removed and there is no risk of explosion.
