Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtration technologies face challenges in efficiently separating particles from non-Newtonian slurries and multiphase mixtures at high flowrates and throughput, leading to fouling and limited process intensification, particularly in industries like petroleum and nuclear waste processing.
Innovation Solution
Mesofluidic separator assemblies that utilize a conduit system with a pressure differential axis and a plurality of members configured to direct smaller particles along a linear path and larger particles along a non-linear path, allowing for rapid separation and collection of larger particles separately from the filtrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dead-end filtration with a single inlet and single outlet is used, then particles larger than characteristic channel dimension are trapped to form filter cake, but cake and depth fouling occur faster at higher concentrations and flowrates
Solution Approach 1:
The single filtration channel is segmented into multiple parallel channels, each with its own inlet and outlet. This segmentation distributes the slurry flow across multiple pathways, reducing the concentration of particles in any single channel and thereby slowing down cake and depth fouling while maintaining high separation efficiency
Solution Approach 2:
The invention transitions from a single-dimensional linear flow path to a multi-dimensional parallel channel structure. By adding spatial dimensions (multiple channels arranged in parallel), the system increases throughput capacity without compromising particle separation performance
2Productivity
If filter banks increase cross-sectional area to match flowrate requirements, then flowrate capacity is achieved, but footprint increases significantly
Solution Approach 1:
Multiple filtration channels are merged into a single integrated housing structure with a compact arrangement. The parallel channels are positioned closely together, sharing common inlet and outlet manifolds, which combines the functionality of multiple filters into a single compact unit that achieves high flowrate capacity without proportionally increasing footprint
3Manufacturing precision
If conventional filters and sieves are used, then particle removal is achieved, but process throughput is limited and back flushing is required
Solution Approach 1:
The parallel channel structure with separate inlets and outlets enables continuous slurry flow through the filtration system without interruption. Unlike conventional filters that require back flushing to maintain throughput, this design allows uninterrupted particle separation as slurry continuously flows through multiple channels, maintaining both separation efficiency and high process throughput
4Productivity
If hydrocyclones are used for particle separation, then high flowrate is achieved, but cost increases and efficacy reduces at lower particle sizes
Solution Approach 1:
The invention replaces the complex mechanical hydrocyclone system with a simpler parallel channel filtration structure. Instead of using centrifugal force and complex vortex geometry, the system uses straightforward parallel channels with controlled flow distribution, achieving high flowrate capability at lower cost and maintaining effectiveness across a broader particle size range
