Method of treatment of spent ion-exchange resins for disposal and device for its implementation

A device for treatment of spent ion-exchange resins for disposal, the device comprising:

• a loading tank connected to a pipeline for feeding a mixture of spent ion-exchange resins and transport water and a pipeline for draining transport water;
• a drying chamber equipped with stirrers;
• a metering device connected to the drying chamber equipped with stirrers;
• an inclined feed screw located between the loading tank and the metering device;
• a vacuum pump connected by a pipeline to the drying chamber;
• a heated gas filter installed on the pipeline between the drying chamber and the vacuum pump;
• a docking unit for discharging the treated ion exchange resins;
• a high-temperature furnace with stirrers;
• and a feeding device located between the drying chamber and the high-temperature furnace, the high-temperature furnace being equipped with a vacuum drying and gas purification system, and the docking unit for discharging the treated ion-exchange resins being connected to a lower part of the high-temperature furnace.
