Diffusion Pipe Slit Placement for Even Air Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diffusion pipes face issues with backflow of sludge due to membrane expansion and contraction, leading to clogging and uneven air diffusion, and residual cleaning solutions interfere with air emission after cleaning, hindering quick recovery of air diffusion efficiency.
Innovation Solution
The diffusion pipe design features a tubular membrane body with diffusion slits avoiding areas corresponding to through-holes on the membrane support body, allowing air to flow through a space before discharge, and strategically placed through-holes on the membrane support body for efficient cleaning solution drainage and air distribution, ensuring even air diffusion and quick recovery post-cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If diffusion slits are formed all over the membrane body including areas facing through-holes, then air can be discharged from all regions, but air diffusion becomes uneven and diffusion slits near through-holes lose elasticity and open widely causing sludge to be pulled in
Solution Approach 1:
The patent applies local quality by differentiating the membrane structure in different regions: diffusion slits are provided only in regions that do not overlap with through-hole areas, while other regions have different structural characteristics. This ensures that each region performs its specific function optimally without interfering with others, preventing uneven air diffusion and sludge clogging.
Solution Approach 2:
The patent introduces asymmetry in the spatial arrangement of diffusion slits and through-holes. By positioning diffusion slits in regions that do not overlap with through-hole projection areas, the structure creates an asymmetric configuration that optimizes air flow paths and prevents the membrane from opening excessively at through-hole locations, thereby maintaining uniform air diffusion.
2Productivity
If cleaning solution is supplied into the membrane support body to clean diffusion slits, then air diffusion efficiency is recovered, but residual cleaning solution interferes with air emission through through-holes preventing quick recovery
Solution Approach 1:
The patent segments the membrane structure into distinct functional regions: through-holes in the support body for air supply and cleaning solution drainage, and diffusion slits in the membrane body for air discharge. This segmentation allows cleaning solution to be efficiently drained through through-holes without remaining in diffusion regions, enabling quick recovery of air diffusion efficiency.
Solution Approach 2:
The patent uses through-holes as an intermediary structure that serves dual purposes: supplying air to the membrane and draining cleaning solutions. This intermediary structure facilitates the separation of air flow and cleaning solution flow paths, allowing cleaning solutions to be efficiently removed without interfering with subsequent air emission through through-holes.
3Productivity
If membrane body repeatedly expands and contracts with air flow, then air is discharged through diffusion slits, but sludge flows in through diffusion slits during expansion contraction process
Solution Approach 1:
The patent applies local quality by providing diffusion slits only in specific regions of the membrane body that do not overlap with through-hole areas. This localized configuration ensures that membrane expansion and contraction occur in regions optimized for air discharge, while through-hole regions handle air supply and sludge prevention, reducing the risk of sludge clogging.
