するためである。In the same figure, the waste ion exchange resin in the water slurry introduction line 1 is normally in the state of water slurry, but the water content is often 75 to 95% by weight in consideration of ease and efficiency of transportation. In addition, the waste ion exchange resin in the supplied water slurry is
If the mesh size is 0.00 mesh or more, no particular pulverization process is required, but if the particle size is less than 100 mesh, such as granular waste ion exchange resin, 95% by weight or more of it is crushed by a wet pulverizer 20 to improve combustion efficiency. It is desirable to supply the metering pump 2 to the metering pump 2 after pulverizing it. Crusher 20
Although the type is not particularly limited, a two-stage batch type crusher equipped with rod crushing means and ball crushing means is preferably used. The inclination angle α of the hopper of the metering pump 2 varies depending on the moisture content and the particle size of the waste ion exchange resin, but is usually preferably 85° or more. Since this hopper is equipped with a rotating bridge breaker 21, the performance of the metering pump is ensured. The water slurry containing the powdered waste ion exchange resin is supplied to the water slurry supply port 5 of the incinerator 4 via the water slurry supply line 3. The reason why the particle size of the waste ion exchange resin in the water slurry is controlled in this way is to ensure that the incineration treatment is carried out sufficiently, as will be described in the later examples.

Fuel gas is supplied from the incinerator 4 to preheat the incinerator 4 and maintain its temperature. Further, the hot air generated in the hot blast furnace 6 is blown into the vicinity of the water slurry supply port 5 of the incinerator 4 through the swirling flame flow generation nozzle 9 to generate a swirling flame flow. This swirling flame flow can be adjusted by adjusting the installation angle of the swirling flame flow generating nozzle 9, the nozzle diameter, the amount of hot air supplied from the hot air generating furnace 6, and the like. Incidentally, it is preferable that the incinerator 4 is preheated to about 1000° C. with fuel. The situation inside the furnace, such as the generation state of the swirling flame flow, can be monitored through the viewing window 10. Incineration is preferably carried out at a temperature of 1,200 to 1,400°C from the viewpoint of combustion efficiency and refractories in the furnace.
