Abstract

Die Erfindung betrifft ein Verfahren zur Volumenreduk­ tion von schwach radioaktiven Abfällen in einer mit getrenn­ ter Feststoff- und Flüssigkeitseingabe ausgerüsteten An­ lage, bei der die Flüssigkeit über einen Filter einem Abwas­ serbehälter und die trockenen Feststoffe einem Feststoffbe­ hälter zugeleitet werden. The invention relates to a method for volume reduction tion of weakly radioactive waste in one with separate Solid and liquid input equipped equipment position where the liquid passes through a filter to a waste water water container and the dry solids in a solids container containers are supplied.

Anlagen dieser Art sollen insbesondere in Kranken­ häusern und Universitätskliniken od.dgl. eingesetzt wer­ den. Plants of this type are said to be particularly useful in the sick houses and university hospitals or the like used who the.

Die Volumenreduktion ist im Hinblick auf die im wesent­ lichen volumenabhängigen Kosten der Zwischen- bzw. End­ lagerung dieser Abfälle von besonderer wirtschaftlicher Bedeutung. The volume reduction is essential in terms of volume-dependent costs of the intermediate or final Storage of this waste is particularly economical Importance.

Es ist wesentliches Ziel der Erfindung, ein Verfahren zu nennen, das eine besonders kompakte Ausbildung einer solchen Anlage ermöglicht. Es ist vorgesehen, daß die Fest­ stoffe einem Zerkleinerer zugeleitet werden und nach Durchgang durch diesen das bereits trockene Gut aus dem Verfahren abgetrennt und dem Feststoffbehälter zugeführt wird, während das feuchte Gut in einem Spül-Trocknungssy­ stem getrocknet und dann ebenfalls dem Feststoffbehälter aufgegeben wird. Die mit der Heißluft ausgetragene Feuch­ tigkeit wird kondensiert und das Kondensat dem Abwasser­ behälter zugeleitet. Das dem Feststoffbehalter aufgegebene Gut wird durch eine Preßvorrichtung, vorzugsweise bei Zu­ gabe von Klebstoff, kompaktiert. It is an essential object of the invention to provide a method call that a particularly compact training one enables such an installation. It is envisaged that the festival substances are sent to a shredder and after Passage through this the already dry good from the Process separated and fed to the solids container while the damp material is in a rinsing and drying system stem dried and then also the solids container is abandoned. The dampness carried off with the hot air activity is condensed and the condensate to the wastewater container supplied. The one given to the solid container Is good by a pressing device, preferably at Zu administration of adhesive, compacted.

Durch die Trennung der zerkleinerten, bereits trok­ kenen Feststoffe von den zerkleinerten feuchten Feststoffen kann die Anlage als solche wesentlich kleiner dimensioniert werden, da sie nicht das gesamte Feststoffvolumen für den weiteren Durchgang berücksichtigen muß. By separating the shredded, already dry no solids from the crushed moist solids the system itself can be dimensioned much smaller as they do not represent the entire solid volume for the must consider further passage.
