Method and device for processing by oxidation by wet waste materials, radioactive liquids containing fillers of different materials

摘要

The present invention relates to a method and device for the treatment by wet waste containing fillers oxidizable of various materials, in particular of mineral materials, organic materials and possibly of bio - mineral materials, in particular of organic resins, these charges are radioactive oxidizable. This device (10) comprises a reactor (11) consisting of a column of treatment, a first heat exchanger (12) located upstream of reactor (11) and a second heat exchanger (13) arranged downstream of the reactor. The solution to be treated contain fillers of inorganic matter which has been added an oxidizing gas is injected to treatment in the reactor (11) after preheating it in the first heat exchanger (12). At its output of the reactor (11), the mixture is treated hot is divided into two fragments of the hot flow. The first fragment of flow, whose flow rate is kept constant by a column of diaphragms (30), is used to regulate the temperature of the first heat exchanger (12).
