Die bekannten. Vorrichtungen zum Behandeln von radioaktiven Flüssigkeiten und insbesondere zu deren Filtrierung erlauben kein Auswechseln der Behandlungselemente, ohne den an die Zuführungs- und Ableitungsrohre für die Flüssigkeit angeschlossenen Teil 5 der Vorrichtung abzunehmen. Daher bringt das Loslösen der gesamten Behandlungselemente von den damit verbundenen Rohrleitungen Schwierigkeiten mit sich und eine gewisse Gefahr für das Personal, das diese Vorgänge ausführen muß.The known. Devices for the treatment of radioactive liquids and in particular for their Filtration do not allow the treatment elements to be changed without the supply and discharge pipes to remove part 5 of the device connected to the liquid. Hence the loosening brings about of the entire treatment elements from the associated pipelines with difficulties themselves and a certain danger to the personnel who have to carry out these operations.
Die Erfindung bezweckt eine auseinandernehmbare Vorrichtung zum Behandeln von radioaktiven Flüssigkeiten zu schaffen, die diesen Nachteil vermeidet.The invention aims at a disassemblable device for treating radioactive liquids to create that avoids this disadvantage.

Die in Fig. 1 dargestellte Vorrichtung umfaßt einen feststehenden Behälter 1, der an die Zuführungsleitung! und an die Abflußleitung 3 für das zu behandelnde Strömungsmittel angeschlossen ist. Der feste Behälter 1 ist durch einen Deckel 4 verschlossen, der mittels Schrauben 5 verschraubt und durch eine Dichtung 6 abgedichtet ist. Um das Öffnen des Behälters 1 zu erleichtern, ist auf dem Deckel 4 ein Ring 7 angeordnet.The device shown in Fig. 1 comprises a stationary container 1 which is attached to the supply line! and is connected to the discharge line 3 for the fluid to be treated. Of the fixed container 1 is closed by a lid 4, which is screwed by means of screws 5 and by a Seal 6 is sealed. In order to facilitate the opening of the container 1, a is on the lid 4 Ring 7 arranged.
Im Innern dieses Behälters 1 ist ein zweiter Behälter 8 vorgesehen, der aus einem im wesentlichen zylindrischen Teil 9, einem Deckel 10 und einem Boden 11 besteht, der mit dem Teil 9 einen Ringspalt 12 bildet. Der Deckel 10 und der Boden 11 sind mittels Schrauben 13 bzw. 14 an dem Teil 9 befestigt.Inside this container 1, a second container 8 is provided, which consists of a substantially cylindrical part 9, a cover 10 and a base 11, which with part 9 has an annular gap 12 forms. The cover 10 and the base 11 are fastened to the part 9 by means of screws 13 and 14, respectively.
Auf dem Deckel 10 ist ein Ring 15 angebracht, um das Herausziehen des gesamten Bauteiles aus dem Behälter 1 zu erleichtern.On the cover 10, a ring 15 is attached to the pulling out of the entire component from the Container 1 to facilitate.
Der Behälter 8 ruht mit einer an seiner Außenfläche vorgesehenen Schulter 16 auf einer Schulter 17 an der Innenfläche des Behälters 1, wobei ein als Dichtung dienendes Aluminiumblatt 18 dazwischengelegt ist.The container 8 rests on a shoulder 17 with a shoulder 16 provided on its outer surface on the inner surface of the container 1 with an aluminum sheet 18 serving as a seal interposed therebetween is.
Die Anordnung der Schultern 16 und 17 an der Innenfläche des Behälters 1 bzw. der Außenfläche des zweiten Behälters 8 ist so getroffen, daß zwischenThe arrangement of the shoulders 16 and 17 on the inner surface of the container 1 and the outer surface of the second container 8 is made so that between
309 508/206309 508/206
dem unteren Bereich des Behälters 8 und dem Boden des Behälters 1 ein freier Raum 19 gelassen ist.the lower area of the container 8 and the bottom of the container 1 a free space 19 is left.
In dem Hauptteil 9 des zweiten Behälters ist eine Öffnung 20 vorgesehen, durch die das zu behandelnde Strömungsmittel einfließt. In dem Deckel 10 ist eine Ausnehmung für einen Schieber 21 vorgesehen, der durch eine fest mit diesem verbundene Schulter 22 gehalten ist. Im Innern des zweiten Behälters sind die Einrichtungen zum Behandeln des radioaktiven Strömungsmittels, z. B. Filterelemente, angeordnet. idIn the main part 9 of the second container is a Opening 20 is provided through which the fluid to be treated flows. In the lid 10 is a Recess is provided for a slide 21, which is secured by a shoulder 22 that is firmly connected to it is held. Inside the second container are the facilities for treating the radioactive fluid, z. B. filter elements arranged. id
In Fig. 1 sind z. B. Filtereinsätze dargestellt, die aus Lochscheiben 24 aus gesintertem nichtrostendem Stahl aufgebaut sind.In Fig. 1, for. B. filter cartridges are shown made of perforated disks 24 made of sintered stainless Steel are constructed.
Die Anordnung ist durch eine Umkleidung 25 wärmegeschützt.The arrangement is thermally protected by a casing 25.
Bei normalem Betrieb fließt das zu behandelnde verschmutzte Strömungsmittel durch die Leitung 2 und tritt durch die Öffnung 20, die in dem Teil 9 vorgesehen ist, in den Behälter ein, in dem sich die Filterelemente 23 befinden. Das Strömungsmittel ist gezwungen, den Behälter 8 zu durchfließen, in dem sich die Filterlemente befinden. Es tritt aus diesem durch den Ringspalt 12 aus und verläßt den Behälter 1 durch eine Abflußleitung 3. Das verschmutzte Strömungsmittel kann nicht in Berührung mit dem behandelten Strömungsmittel, das die Leitung 3 der Vorrichtung verläßt, kommen, da die Aluminiumdichtung 18 das eintretende und austretende Strömungsmittel hermetisch trennt.During normal operation, the polluted fluid to be treated flows through line 2 and enters through the opening 20 provided in the part 9 into the container in which the Filter elements 23 are located. The fluid is forced to flow through the container 8 in which the filter elements are located. It emerges from this through the annular gap 12 and leaves the container 1 through a drain line 3. The contaminated fluid cannot come into contact with the treated fluid that leaves the line 3 of the device, come because the aluminum seal 18 hermetically separates the entering and exiting fluid.
Wenn man den Filter auseinandernehmen will, nimmt man nach dem Lösen der Schrauben 5 zuerst den Deckel 4 vom Behälter 1.If you want to take the filter apart, after loosening the screws 5 you first take it the lid 4 of the container 1.
Wenn der Behälter 1 offen ist, zieht man den zweiten Behälter 8 mittels des Ringes 15 heraus. Bei der Anhebbewegung desselben verschließt dieser durch den Schieber 21 die Strömungsmittelzuflußöffnung20. Hierzu sind der obere Bereich des Teiles 9 des Behälters 8, und der untere Bereich des Schiebers 21 mit komplementären Profilen versehen, die das Zusammensetzen beim Herausnehmen des zweiten Behälters 8 aus dem Behälter 1 ermöglichen.When the container 1 is open, the second container 8 is pulled out by means of the ring 15. at the lifting movement of the same closes the fluid inflow opening 20 through the slide 21. For this purpose, the upper area of the part 9 of the container 8, and the lower area of the slide 21 provided with complementary profiles that the assembly when removing the second Allow container 8 from container 1.
Der Ringspalt 12 im unteren Bereich des zweiten Behälters ist so ausgebildet, daß sich zugleich ein Strahlenschutz ergibt. Der zweite Behälter 8, der durch den Schieber 21 verschlossen ist, bietet also einen vollständigen Strahlenschutz.The annular gap 12 in the lower region of the second container is designed so that at the same time a Radiation protection results. The second container 8, which is closed by the slide 21, therefore offers complete radiation protection.
Der Wiederzusammenbau der Anordnung geschieht mit derselben Leichtigkeit, wobei die Strömungsmittelzuflußöffnung 20 durch Anhalten des Schiebers bei der Abwärtsbewegung des zweiten Behälters 8 in den Behälter 1 entriegelt wird.Reassembly of the assembly is done with the same ease, with the fluid inflow opening 20 is unlocked by stopping the slide during the downward movement of the second container 8 into the container 1.
