Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electrical separators, the increasing variability of fluid interfaces and rapid changes in the location of highly conductive interface layers pose a risk of electrical contact with electrodes, potentially damaging the equipment. There is a need for fast and reliable detection of incipient or imminent contact between highly conductive fluids and electrodes.
Innovation Solution
The implementation of a separator system that includes a separation vessel with an electric field assembly and detector electrodes. The detector electrodes are positioned to detect conductive fluids before they reach the electric field electrodes, and are powered by a dedicated power unit to monitor changes in electrical conductivity, triggering control actions to maintain safe distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If throughput is increased in electrical separators, then productivity is improved, but the risk of electrical contact between conductive interface layers and electrodes increases
Solution Approach 1:
The detector electrodes are positioned to detect the presence of conductive fluids before they reach the electric field electrodes. This preliminary detection allows the system to take corrective action in advance, preventing electrical contact while maintaining high throughput operations.
Solution Approach 2:
The detector electrodes serve as an intermediary detection system between the conductive interface layers and the electric field electrodes. They provide early warning of approaching conductive fluids, enabling preventive control actions before damage can occur to the main electrodes.
2Reliability
If detector electrodes are positioned to detect conductive fluids early, then reliability is improved, but device complexity increases
Solution Approach 1:
The electrode system is segmented into two functional groups: detector electrodes for early detection and electric field electrodes for separation. This segmentation allows each group to be optimized for its specific function while working together as an integrated system.
Solution Approach 2:
Both detector electrodes and electric field electrodes use the same basic electrode structure and electrical connection principles. The system achieves multi-functionality by positioning and configuring identical or similar electrode elements to perform both detection and separation functions.
