Lumps Discharge System for Polymer Reactor Agglomerate Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The formation of agglomerates or lumps during the production of particulate or granular products, such as polymer particulates, leads to nonuniform product sizes and can cause process interruptions, requiring costly and time-consuming reactor cleaning.
Innovation Solution
A system and process for removing particle agglomerates from a particulate product stream, involving a diverter system that retains agglomerates while allowing smaller particles to pass through, and uses a carrying fluid to dislodge and convey the agglomerates to a collector vessel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a diverter system is used to retain agglomerates, then agglomerate removal effectiveness is improved, but device complexity increases
Solution Approach 1:
The diverter system divides the product stream into two paths: one for particles of desired size that pass through, and another for agglomerates that are retained. This segmentation allows selective removal of agglomerates while maintaining continuous flow of合格 particles, resolving the contradiction by improving removal effectiveness through structural division rather than complex processing mechanisms
Solution Approach 2:
The diverter system acts as an intermediary device between the reactor and downstream processing. It temporarily holds agglomerates and releases them at controlled intervals, mediating between continuous production requirements and periodic cleaning needs. This intermediary function improves agglomerate removal effectiveness while maintaining relatively simple device structure
2Productivity
If the diverter system operates continuously to remove agglomerates, then productivity is improved, but loss of time for discharge operations increases
Solution Approach 1:
The diverter system operates periodically rather than continuously for discharge operations. It accumulates agglomerates during normal operation and then performs periodic discharge cycles. This periodic action maintains high productivity during accumulation phases while limiting time loss during discharge operations, as the system returns to normal operation after each discharge cycle
Solution Approach 2:
The diverter system maintains continuous flow of合格 particles to downstream processes while simultaneously accumulating agglomerates for later removal. The useful action of product transport continues uninterrupted, while agglomerate removal is handled in parallel through periodic discharge operations, thus maintaining productivity while minimizing time loss

Function Achieved in This Case
Effectively prevents the accumulation of agglomerates in the reactor, ensuring continuous process operation, reducing the risk of product nonuniformity, and minimizing downtime and cleaning costs.
Implementation Method 1
