The present application relates to the technical field of catalyst regeneration, in particular to a gas-solid countercurrent enhanced stripping device for catalyst regeneration, comprising: a mounting frame and an inclined plate assembly. The inclined plate assembly is arranged inside the mounting frame, used for guiding the flow of catalyst particles and capable of prolonging the contact time of catalyst particles with water vapor. Further, when the catalyst particles impact the inclined plate assembly under the action of gravity, the inclined plate assembly can absorb kinetic energy through its elastic deformation, converting rigid collision into cushioned contact. Therefore, on the one hand, the impact force of the catalyst particles on the inclined plate assembly is reduced, which not only slows down the wear of the catalyst particles themselves, but also avoids the abrasion of the inclined plate assembly; on the other hand, the slight vibration induced by elastic deformation can disturb the flow state of the catalyst particles, promoting them to spread evenly on the inclined plate assembly, thereby improving the contact efficiency between the catalyst particles and water vapor and further improving the stripping efficiency.
