An integrated waste catalyst cleaning apparatus includes a reaction unit, an organic solvent unit, an organic acid unit, a drying unit, a condensation unit, a heating band, and control valves formed at transfer paths. The waste catalyst is injected into the reactor. The organic solvent stored in the organic solvent unit is to first-clean the waste catalyst. The organic solvent is discharged after cleaning. The waste catalyst is dehydrated and dried by the drying unit. The organic acid stored in the organic acid unit is to second-clean the waste catalyst. The organic acid is discharged after cleaning. The waste catalyst is dehydrated and dried by the drying unit. |
