AI Technical Summary

Technical Problem

After the existing fast fluidized bed reactor is expanded on a large scale, the mixing efficiency between multiple strands of catalysts in the mixing area of ​​the reaction chamber and between the gas-solid phases is low, resulting in a degradation of reaction performance.

Method used

A specific spoiler member is designed, including a flow guide and a mixing part. The flow guide is mixed with the gas solid phase through a flow guide plate. The mixing part enhances the interphase disturbance of the gas solid phase through a spoiler ring, and optimizes the feed and distribution of the catalyst in combination with the solid distribution piece.

Benefits of technology

The mixing efficiency between multiple solid phase materials and between gas solid phases is significantly improved, the performance of the reactor is improved, and the production efficiency, economicality and environmental protection of the overall process are improved.
