Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid processing apparatuses with rotating processing surfaces face inefficiencies in mixing and reaction due to large outlet areas in the flow path of the second fluid, leading to insufficient contact and incomplete reactions, along with challenges in scaling up and detecting clogging issues.
Innovation Solution
A fluid processing apparatus with processing surfaces that rotate relative to each other, featuring a flow path for the second fluid with multiple divided outlets to enhance contact area and efficiency, and a detachable flow-path dividing member for easy maintenance and experimentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large outlet area is used in the flow path of the second fluid, then the flow rate is improved, but the contact area between fluids is reduced leading to insufficient mixing
Solution Approach 1:
The outlet part of the flow path for the second fluid is divided into multiple smaller outlets. This segmentation allows the total flow rate to be maintained while increasing the number of contact points between the first and second fluids, thereby improving mixing efficiency without sacrificing productivity
Solution Approach 2:
The outlets are arranged in a specific spatial pattern (e.g., radially distributed) to maximize the contact area between fluids in the processing space. This dimensional arrangement ensures that fluid streams from multiple outlets intersect and mix more effectively throughout the three-dimensional processing region
2Productivity
If the number of microreactors is increased for scaling up, then the production capacity is improved, but the complexity of detecting clogging issues increases
Solution Approach 1:
Multiple processing spaces are integrated into a single apparatus with shared inlet and outlet structures. This merging allows the system to achieve scaling-up effects while maintaining a simplified structure where clogging can be detected and addressed from centralized access points rather than requiring inspection of numerous separate devices
3Ease of repair
If a detachable flow-path dividing member is added for easy maintenance, then the ease of repair is improved, but the device complexity is increased
Solution Approach 1:
The flow path structure is segmented into detachable components, specifically the flow-path dividing member that can be removed and replaced. This segmentation enables easy maintenance and cleaning of critical flow paths without disassembling the entire apparatus, while the modular design minimizes the added complexity
Solution Approach 2:
The detachable flow-path dividing member serves multiple functions: it divides the flow path, facilitates maintenance access, and can be replaced to modify flow patterns for different experimental conditions. This multi-functionality justifies the added structural complexity by providing versatile operational capabilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus achieves more stable and uniform processing by increasing the contact area between fluids, enhancing mixing and reaction efficiency, and allowing for easier maintenance and experimental flexibility.
Implementation Method 1
since the reaction fundamentally depends on speed of molecular diffusion
Implementation Method 2

AI summary
Equipment for treating a matter to be treated more stably and uniformly between approaching/receding treatment planes in a treatment section where at least one plane can rotate relatively to the other plane. Treatment is performed by introducing a first fluid containing a matter to be treated between the treatment planes, introducing a second fluid containing the matter to be treated between the treatment planes from a channel independent from the channel which introduced the first fluid and communicating with the space between the treatment planes and then mixing and stirring them between the treatment planes. The outlet portion of the channel introducing the second fluid to the space between the treatment planes is provided with a plurality of split channels.
