DEVICE FOR OIL-CLEANING OF USED-CATALYST FOR RHDS AND VRDS DESULFURIZATION

摘要

The present invention relates to an apparatus for removing oil from a spent desulfurization catalyst of RHDS (Residual Hydro Desulfurization) and VRDS (Vacuum Residue Desulfurization) in order to remove oil from the spent desulfurization catalyst via a pre-process prior to removal of sulfur and heavy metals which cause the deactivation of the spent desulfurization catalyst occurring in RHDS and VRDS processes. The apparatus for removing oil of the present invention comprises: a storage hopper for storing a spent catalyst which contains oil; a raw material injection controller provided in a lower part of the storage hopper and controlling an amount of the spent catalyst dispensed by the storage hopper so that the amount becomes a fixed amount; a mesh basket for accommodating the spent catalyst dispensed in a fixed amount by the raw material injection controller; a transfer hoist for transferring the mesh basket accommodating the spent catalyst to a solvent tub; a plurality of solvent tubs for accommodating the mesh basket transferred from the transfer hoist and dissolving oil contained in the spent catalyst; a transport conveyor for receiving and transferring the spent catalyst to be unloaded from the mesh basket, wherein the catalyst has passed through the plurality of solvent tubs; an explosion-proof blower for applying hot air to the spent catalyst transferred by the transfer conveyor and removing solvent remaining in the spent catalyst; and a gas absorption tower for purifying the gas discharged.
