Rotating Deflector Assembly for Uniform Solid Particle Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for loading solid particles into reactors, such as chemical reactors, often result in unsatisfactory filling profiles due to anisotropic particle shapes and varying permeability of the moving assembly, leading to uneven density distribution and hydrodynamic issues, which can cause operational inefficiencies and losses.
Innovation Solution
A device with a movable assembly featuring adjustable deflectors, where the distance between the highest stages can be modified based on the speed of rotation, allowing for real-time adjustment of permeability to improve the flatness of the loading profile without interrupting the loading process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the speed of rotation of the moving assembly is increased to correct filling front deviations, then the loading profile flatness is improved, but the permeability of the moving assembly decreases significantly
Solution Approach 1:
The patent applies the dynamics principle by making the deflector assembly rotatable rather than fixed. The deflectors can rotate at adjustable speeds to dynamically adapt to different loading conditions. This allows the system to optimize both permeability and loading profile flatness by controlling the rotational speed, resolving the contradiction between these two parameters that would be fixed in a static system.
Solution Approach 2:
The patent applies parameter changes by adjusting the rotational speed of the moving assembly as a controllable parameter. By varying the rotation speed, the system can modify the permeability characteristics and loading profile simultaneously. This dynamic parameter adjustment allows optimization of both manufacturing precision (loading profile flatness) and quantity of substance (permeability) that would otherwise be fixed trade-offs.
2Quantity of substance
If the distance between deflector stages is reduced to increase permeability, then particle distribution is improved, but the loading profile flatness deteriorates
Solution Approach 1:
The patent uses dynamics by making the deflector stages rotatable rather than fixed at fixed distances. The rotational movement allows the deflectors to dynamically adjust their effective spacing and positioning relative to the particle flow. This dynamic configuration enables simultaneous optimization of permeability and loading profile flatness that would be impossible with fixed, non-rotating deflectors at constant distances.
Solution Approach 2:
The patent applies preliminary action by pre-positioning multiple deflector stages at different locations before the particle load arrives. These pre-positioned deflectors work together in a coordinated rotational sequence to guide particles from the beginning of the loading process, ensuring uniform distribution and flat profile formation while maintaining appropriate permeability through their configured spacing and rotational dynamics.
3Stability of the object's composition
If fixed deflectors are used to create random particle deviation, then particle dispersion is achieved, but the system complexity and steric bulk increase
Solution Approach 1:
The patent applies merging by combining multiple deflector elements into a single integrated rotating assembly. Instead of using separate fixed deflectors positioned throughout the reactor, the invention merges them into one unified moving structure that rotates to provide dispersion. This reduces the overall system complexity and steric bulk while maintaining the particle dispersion uniformity that would require multiple fixed deflectors.
Solution Approach 2:
The patent uses dynamics by replacing static fixed deflectors with a single rotatable moving assembly. The rotational motion of this single unit creates the necessary particle deviation and dispersion effects that would require multiple complex fixed deflector arrangements. This dynamic approach simplifies the overall system structure while achieving the same particle distribution uniformity.
