Actuated Valve Control for Solid Feed Pump Compaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid feed pumps face challenges in maintaining consistent compaction and permeability of solid feeds due to variability in feedstock properties, affecting pump performance and downstream processes.
Innovation Solution
A system with an actuated valve in the outlet of the solid feed pump, controlled by feedback sensors, adjusts compaction and permeability to maintain a dynamic seal and optimize pump performance across varying feedstocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solid feed pump transports solid feed with variable feedstock properties, then productivity is maintained, but compaction and permeability become unstable
Solution Approach 1:
The patent applies dynamics by making the valve position adjustable and controllable in real-time. The actuated valve can dynamically change its opening degree in response to varying feedstock properties, allowing the system to adapt to different compaction and permeability requirements while maintaining stable operation and consistent productivity
Solution Approach 2:
The patent changes the valve opening degree as a controllable parameter to regulate solid feed flow characteristics. By adjusting this parameter, the system can control the compaction and permeability of the solid feed, enabling adaptation to variable feedstock properties while maintaining stable process conditions
2Stability of the object's composition
If actuated valve is added to adjust compaction, then compaction stability is improved, but device complexity increases
Solution Approach 1:
The patent implements feedback control where the actuated valve is controlled based on process conditions. This feedback mechanism allows the valve to automatically adjust its position to maintain stable compaction, reducing the need for manual intervention and complex control systems while achieving consistent results
Solution Approach 2:
The system achieves self-regulation through the actuated valve that automatically adjusts solid feed flow characteristics. The valve responds to process conditions and maintains stable compaction without requiring external complex control mechanisms, enabling the system to service itself
