Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas-liquid cyclone separators face challenges in achieving high separation efficiency while handling large treatment capacities, due to disturbances in gas flow that lead to turbulence and entrainment of droplets, resulting in reduced separation efficiency and the need for multiple devices in parallel, which introduces uneven distribution and channeling issues.
Innovation Solution
A gas-liquid separation device with a vertically extending outer housing and inner housing, featuring a cyclone mechanism and annular space, where the gas-liquid mixture enters as a swirling flow, reducing upward gas flow disturbances and enhancing centrifugal separation efficiency through a combination of codirectional and reverse flow modes, with features like a grille and anti-impact baffle to manage gas and liquid flow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the gas velocity is increased to meet large treatment capacity requirements, then the productivity is improved, but the gas flow turbulence increases and droplets are sheared and broken into smaller droplets, causing severe entrainment and reducing separation efficiency
Solution Approach 1:
The separation device is divided into multiple independent separation chambers (first separation chamber and second separation chamber) with separate cyclone structures. Each chamber handles a portion of the gas flow independently, allowing the system to process large volumes without increasing velocity in any single chamber, thereby maintaining separation efficiency while achieving high productivity.
Solution Approach 2:
The patent introduces a vertical dimension by stacking separation chambers one above the other. The gas-liquid mixture enters the first separation chamber from the top, and the separated gas flows into the second separation chamber from the bottom. This multi-level arrangement increases treatment capacity without requiring increased horizontal velocity that would cause turbulence and droplet breakup.
2Productivity
If multiple separation devices are connected in parallel to increase treatment capacity, then the productivity is improved, but the inlet gas distribution becomes uneven and gas channeling occurs among devices, significantly reducing separation efficiency
Solution Approach 1:
Multiple separation chambers are merged into a single integrated device structure. The chambers share common inlet and outlet manifolds that distribute gas flow evenly to each chamber. This unified structure eliminates the uneven distribution and channeling problems that occur when separate devices are connected in parallel, as the internal flow distribution is optimized as a whole system.
Solution Approach 2:
The patent designs the inlet manifold and outlet manifold with equal pressure distribution characteristics. All separation chambers are positioned to experience approximately equal pressure drops and flow rates, creating equipotential flow conditions. This prevents gas channeling where some chambers would receive disproportionately more flow, ensuring each chamber operates at optimal efficiency while collectively handling large treatment capacities.
3Device complexity
If a single separation device is used to maintain simple structure, then the device complexity is reduced, but it cannot meet large treatment capacity requirements without compromising separation efficiency
Solution Approach 1:
Separation chambers are nested vertically within a single device housing. The first separation chamber is positioned above the second separation chamber, with gas flowing from the first chamber into the second chamber. This nested arrangement allows multiple separation stages to be contained within one compact device, achieving high treatment capacity without requiring multiple separate devices or complex external piping arrangements.
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 solution effectively reduces turbulence, increases centrifugal force, and improves separation efficiency, allowing for higher gas flow treatment capacity per unit time with a simpler structure that is easy to install and maintain, minimizing entrainment and enhancing overall separation performance.
Implementation Method 1
the centrifugal force can reach dozens of times of gravity or even more. Thus, the centrifugal separation has a higher efficiency than the gravity separation
Implementation Method 2
a gas flow enters a separation device tangentially through an inlet of a cyclone separator to form a double-vortex flow inside the cyclone separator
Implementation Method 3
Droplets are separated from a gas-phase fluid under the centrifugal force, coalesce after moving to a sidewall, and flow downward to a liquid outlet along the sidewall

AI summary
A gas-liquid separation device comprises: an outer housing extending vertically, which is provided with a gas outlet at an upper end of the outer housing and a liquid outlet at a lower end of the outer housing; an inner housing disposed in the outer housing and extending vertically, an upper end of the inner housing being coupled to the outer housing in a sealed manner, a lower end of the inner housing being opened, with an annular space formed between the outer housing and the inner housing; a feeding tube inserted into the outer housing and communicated with the inner housing, with a cyclone mechanism between the feeding tube and the inner housing to output fluid into the inner housing as a swirling flow. The present disclosure can reduce the disturbance of the downward gas flow and the upward gas flow in the separation space, thus improving the separation efficiency.
