Fluid Dispersing Device Uniform Flow Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat exchanger-type reactors face challenges in efficiently dispersing fluids at a uniform flow rate, leading to unnecessary circulation and suboptimal fluid distribution within the reactor.
Innovation Solution
A fluid dispersing device with a specific structure, including a tubular first wall portion and a second wall portion with circular members and a disk-like member, is used to disperse the fluid efficiently into multiple fluid groups flowing in different directions, ensuring uniform distribution into reaction channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a central hole is provided in the diffuser to supply fluid, then the fluid can be introduced into the reactor, but the fluid flow rate increases after passing through the central hole causing agitation and unnecessary circulation around the diffuser
Solution Approach 1:
The diffuser is divided into multiple peripheral holes instead of a single central hole. This segmentation distributes the fluid flow into multiple smaller streams, preventing the high-velocity single jet that causes agitation and unnecessary circulation. The fluid is introduced through several peripheral holes arranged around the diffuser perimeter, achieving uniform distribution without harmful flow patterns.
Solution Approach 2:
Instead of introducing fluid through a central hole from the bottom, the invention inverts the approach by providing holes at the periphery of the diffuser. This reverses the conventional central-introduction method and eliminates the agitation problem by distributing flow across the periphery rather than concentrating it in the center.
2Manufacturing precision
If the reaction fluid is dispersed in a space facing the openings to achieve uniform flow rate, then uniform distribution can be achieved, but the device complexity increases
Solution Approach 1:
The invention extracts and eliminates the complex dispersing space structure from the system. Instead of creating a separate dispersion zone with additional components, the uniform flow rate distribution is achieved directly at the diffuser level through optimally positioned peripheral holes, simplifying the overall device structure.
Solution Approach 2:
The diffuser holes are strategically positioned at the periphery with specific spacing and orientation. This local optimization of hole placement creates uniform flow distribution across the reaction channels without requiring a complex overall dispersing structure. Each peripheral hole is positioned to target specific openings, achieving precision through local design rather than global complexity.
