The utility model discloses a tip sclerosis device for denitration catalyst, including being used for holding the cell body of required hardening liquid when the denitration catalyst hardens with its tip is used for driving the wheel that the cell body removed, and be used for with the cell body is fixed at subaerial mounting, cell body open -top, denitration catalyst and hardening liquid pass through the opening gets into in the cell body, it is used for the push -and -pull still to be equipped with on the cell body the handrail of cell body, the wheel rotationally sets up the bottom of cell body. The utility model discloses tip sclerosis device can remove the position of regeneration denitration catalyst according to actual conditions, and the rethread mounting hardens the device with the tip to be fixed subaerial, adds the cell body with denitration catalyst and hardening liquid, carries out the tip hardening treatment of denitration catalyst. The utility model is suitable for a tip hardening treatment of denitration catalyst in regenerative process.
