Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Taylor reactors have limitations in diversifying the flow field environment, which restricts the mixing effect and interface mass transfer efficiency during the preparation of powder particle materials.
Innovation Solution
A composite vortex reactor is designed, combining a Rankine cyclone reactor and a Taylor vortex reactor, where two types of fluids enter through separate inlet pipes to form a gyro-fluid, which then generates height-variable-size Taylor vortices in an annular reaction space with a gradually increasing cross-sectional area, controlled by a rotary driving device, enhancing the flow field diversity and material mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional Taylor reactor is used, then the structure is simple and the flow field is regular, but the flow field environment is not diversified enough, limiting mixing effect and interface mass transfer efficiency
Solution Approach 1:
The patent combines a Rankine cyclone reactor and a Taylor vortex reactor into a composite vortex reactor. The Rankine cyclone reactor generates gyrofluid with vertical circulation, while the Taylor vortex reactor generates horizontal vortex flows. By merging these two different flow generation mechanisms in a single reactor system, the flow field environment becomes diversified, improving both mixing effect and interface mass transfer efficiency while maintaining relatively simple structure.
Solution Approach 2:
The reactor is segmented into two functional zones: an upper Rankine cyclone reaction zone and a lower Taylor vortex reaction zone. Each zone has its own inlet pipes and flow characteristics. The gyrofluid from the upper zone transitions to the annular reaction space in the lower zone, creating height-variable-size Taylor vortices. This segmentation allows each zone to optimize its specific flow pattern for different stages of the reaction process.
2Manufacturing precision
If the cross-sectional area of the annular reaction space is uniform, then the structure is simple, but the contact reaction time cannot be regulated, affecting mixing effect
Solution Approach 1:
The annular reaction space has a cross-sectional area that gradually increases from bottom to top, creating local variations in flow characteristics. The lower portion with smaller cross-sectional area provides higher velocity and shorter contact time, while the upper portion with larger cross-sectional area provides lower velocity and longer contact time. This local quality variation allows regulation of contact reaction time and improvement of mixing uniformity throughout the reactor.
3Productivity
If only single-phase flow is used, then the system is simple, but the interface mass transfer efficiency is limited
Solution Approach 1:
The composite vortex reactor creates periodic flow patterns through the combination of gyrofluid circulation in the Rankine cyclone zone and vortex flow in the Taylor vortex zone. The flow alternates between upward and downward motion in the cyclone zone, and between inner and outer cylinder rotation in the vortex zone, creating periodic mixing actions that enhance interface mass transfer efficiency between different phases.
