Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flue gas desulfurization and denitrification towers lack an optimized design for the shape, size, and position of flue gas uniformization devices, leading to non-uniform distribution of the flue gas flow field, which affects the adsorption efficiency in the coke layer.
Innovation Solution
A flue gas purification tower with a baffle plate arrangement at the point where the flue gas flow direction changes, featuring various plate types (straight, arched, or straight-arched-straight) with specific radii, hole configurations, and placement to enhance uniform gas distribution and adsorption efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional flue gas uniformization devices are used with standard design, then the device complexity is low, but the flue gas flow field distribution uniformity is poor
Solution Approach 1:
The uniformization device is segmented into multiple baffle plates arranged at different positions and angles within the tower. Each baffle plate divides and redirects the flue gas flow in a specific manner, and the combined effect of multiple segmented elements achieves comprehensive flow uniformization throughout the cross-section.
Solution Approach 2:
Different baffle plates are positioned at specific locations where flow non-uniformity occurs, with each plate having locally optimized orientation and geometry. The baffle plates are strategically placed to address local flow distribution issues rather than applying a uniform design throughout, improving overall flow uniformity through localized interventions.
2Manufacturing precision
If baffle plates are added to improve flow distribution, then the flue gas uniformization effect is improved, but the device complexity increases
Solution Approach 1:
Rather than attempting to perfect flow uniformization throughout the entire tower cross-section, the baffle plates are strategically positioned to address the most critical flow distribution issues. The design applies partial action by focusing uniformization efforts where they provide the greatest benefit to adsorption efficiency, rather than uniformly complexifying the entire system.
3Productivity
If the baffle plate arrangement is optimized for flow uniformity, then the adsorption efficiency is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The baffle plates are arranged in the vertical dimension at different heights within the tower, creating a three-dimensional flow uniformization system. This vertical arrangement allows flow distribution to be optimized at multiple elevation levels simultaneously, improving adsorption efficiency throughout the active coke layer while maintaining manageable complexity through systematic vertical spacing.

Implementation Method 1
a baffle plate arranged in a place where the flow direction of the flue gas from the gas inlet changes
Implementation Method 2
the active coke-based flue gas desulfurization and denitrification technology not only can remove SO2 and NOx in the flue gas at the same time
