Packing Column Support Profile for Low Height and Fluid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support profiles for packing columns, such as T-shaped and cross profiles, result in excessive height or high costs due to the need for slots in liquid collectors, and often obstruct fluid flow channels, reducing efficiency.
Innovation Solution
A support profile with a web section, foot section, and head section, featuring a trapezoidal cross-section and strategically designed widths to maximize area moment of inertia while minimizing coverage over fluid outlets, allowing for efficient fluid flow and reduced overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If T-shaped profiles of great height are used to achieve high area moment of inertia, then the structural strength is improved, but the overall height of the packing column becomes very great
Solution Approach 1:
The supporting profile transitions from a T-shaped design (extending vertically) to an L-shaped design that utilizes horizontal extension. The profile extends horizontally from the vertical web section to provide the necessary area moment of inertia without increasing the vertical height, effectively solving the contradiction by shifting the structural reinforcement to a different spatial dimension.
2Strength
If cross profiles are used to achieve high area moment of inertia, then the structural strength is improved, but the manufacturing cost and complexity increase due to required slots in liquid collector
Solution Approach 1:
The invention extracts only the essential horizontal support function from the complex cross profile, implementing it through a simple L-shaped design. This eliminates the need for additional slots in the liquid collector and reduces manufacturing complexity while maintaining the necessary structural strength through the horizontal flange extension.
Solution Approach 2:
The L-shaped profile uses a simple, inexpensive geometric form that can be manufactured without complex slotting operations. The design prioritizes ease of manufacture over maximizing structural performance, accepting a simpler profile that meets the minimum requirements for supporting the packing material.
3Strength
If profiles with great width in the bearing region are used to achieve high area moment of inertia, then the structural strength is improved, but the coverage of flow channels increases and efficiency is reduced
Solution Approach 1:
The L-shaped profile concentrates its width in the horizontal flange section where it is needed for structural support, while keeping the vertical web section narrow to minimize interference with fluid flow channels. This localized distribution of width provides the necessary area moment of inertia without excessively covering the flow channels in the vertical bearing region.

AI summary
A support for a packing column having a support profile with a web section running in the vertical direction and having lower end and an upper end, and having a larger vertical extension than a horizontal extension. The support also has a foot section connected to the upper end of the web section and a head section connected to the lower end of the web section. The head section has an upper face and a sub-section, the width of the upper face being smaller than width of the sub-section and also smaller than the width of the foot section. The support enables a reduced support height and less coverage.
