Electrostatic Separator Routing Blades for Water-Oil Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrostatic coalescence methods for separating water from oil face challenges in efficiently scaling up for large volume throughput without compromising the size of the separator, as larger volumes of water require effective separation without interference with the coalescing process.
Innovation Solution
An electrostatic separator system with a sloped vessel and routing blades adjacent to electrodes, which directs coalesced water droplets downward and away from the electric field, enhancing gravity-assisted separation and minimizing interference with the coalescing action, allowing for efficient separation and removal of water from the mixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the separator size is increased to handle larger volumes of water, then the throughput capacity improves, but the overall size of the separator increases
Solution Approach 1:
The separator is divided into distinct functional zones: an upper electrostatic coalescence zone with electrodes for water droplet aggregation, and a lower gravity separation zone for water collection. This segmentation allows each zone to perform its specific function efficiently, enabling high throughput without requiring a uniformly large separator volume.
Solution Approach 2:
The patent introduces a vertical dimension to the separation process by implementing a sloped vessel configuration where coalesced water droplets travel downward along the slope under gravity. This vertical movement adds a new dimension to the separation process, increasing throughput capacity without proportionally increasing the horizontal footprint of the separator.
2Productivity
If routing blades are added to redirect coalesced water droplets, then separation efficiency improves, but device complexity increases
Solution Approach 1:
Routing blades are introduced as intermediary elements that facilitate the transition of coalesced water droplets from the electrostatic coalescence zone to the gravity separation zone. These blades act as mediators that guide water droplet movement without requiring complex mechanical systems, control mechanisms, or additional energy input, thus improving separation efficiency while maintaining relatively simple device structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively separates water from oil by creating an electrostatic field and using routing blades to redirect coalesced water droplets, improving separation efficiency and throughput, enabling the handling of larger volumes without compromising the separator's size.
Implementation Method 1
at least one electrode generating an electric field
Implementation Method 2
water droplets, being polar, when subjected to an electric field are coalesced. Electrostatic coalescence is usually practiced by establishing an electric field between electrodes
Implementation Method 3
Larger water droplets tend to gravitate downwardly within the mixture, and the oil, having portions of the water removed therefrom, tends to gravitate upwardly within the mixture
