AI Technical Summary

Technical Problem

Traditional wet calcium desulfurization towers suffer from bottom sedimentation problems during operation, including dead zones in the stirring, slurry sedimentation, and particulate matter deposition, which leads to reduced desulfurization efficiency, equipment failure, and increased maintenance costs.

Method used

The design employs a synergistic approach of cyclone pipe network components and slurry circulation components. The cyclone pipe network components create full-area cyclone disturbance through nested annular cyclone branch pipes, while the slurry circulation components ensure high-concentration slurry circulation. Combined with the control components for real-time monitoring and adjustment, the design eliminates dead zones in the stirring process and breaks up sediments.

Benefits of technology

It achieves full-area, dead-angle-free swirling disturbance in the bottom area of ​​the wet calcium desulfurization tower, improving desulfurization efficiency, reducing equipment maintenance frequency and cost, and lowering the risk of equipment failure.
