Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In gas/liquid separators, stripping agents often fail to flow smoothly to the upper part, leading to condensation and decreased separation efficiency, and vaporized VOCs may re-dissolve in the liquid, reducing vaporization efficiency.
Innovation Solution
A gas/liquid separator design featuring tilted fixed cones with decreasing diameters and strategically placed through-holes, along with caps and partition walls, to facilitate the smooth flow of stripping agents and vaporized VOCs from the lower part to the upper part, preventing re-dissolution and enhancing separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the stripping agent flows through narrow paths between rotary cones and fixed cones, then the residence time is improved, but the stripping agent may condense and separation efficiency decreases
Solution Approach 1:
The internal structure is divided into multiple stages with alternating rotary and fixed cones, creating segmented flow paths. This segmentation allows the stripping agent to flow through multiple zones, ensuring sufficient residence time while preventing condensation through continuous upward movement and vapor phase maintenance.
Solution Approach 2:
The design introduces vertical dimensionality with cones arranged at different heights and tilted orientations. This three-dimensional configuration creates upward flow paths that prevent liquid accumulation and condensation, allowing the stripping agent to maintain vapor phase while achieving adequate residence time through extended vertical traversal.
2Reliability
If VOCs are removed from the fluid, then separation efficiency is improved, but vaporized VOCs may be dissolved again reducing vaporization efficiency
Solution Approach 1:
The continuous upward flow of the stripping agent through multiple cone stages maintains constant vaporization action. The design ensures uninterrupted contact between the stripping agent and vaporized VOCs, preventing re-dissolution by continuously carrying vapors upward through the column to the discharge point.
Solution Approach 2:
The tilted cone configuration and upward flow paths enable rapid upward movement of vaporized VOCs through the column. This rushing through mechanism minimizes the time vaporized compounds spend in the liquid phase, preventing re-dissolution and ensuring efficient vaporization and discharge.
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 design ensures that stripping agents like steam flow smoothly to the upper part without condensation, maintaining VOC concentration and preventing re-dissolution of vaporized VOCs, thereby improving vaporization and separation efficiency.
Implementation Method 1
when a fluid is fed into an upper part of a rotary cone from an upper part of a column, the fluid is spread as a thin film on a surface of the rotary cone by centrifugal force and flows to a lower part of the rotary cone
Implementation Method 2
a gas/liquid separator is operated under a vacuum condition such that vaporization of VOCs is satisfactorily carried out
Implementation Method 3
a stripping agent fed via a lower part of a column might not flow up to an upper part of the column in a process of migrating to the upper part of the column along narrow paths between the rotary cones and the fixed cones
