Inclined Flow Path Gas-Liquid Separator for Better Phase Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas-liquid separators struggle to enhance gas-liquid separation performance, as merely increasing the area of the opening at the bottom of the baffle plate to reduce gas flow speed is insufficient.
Innovation Solution
A gas-liquid separator design featuring a container with an inclined flow path that extends diagonally downward, causing the gas-liquid two-phase flow to collide with the second side part below the outlet, thereby enhancing separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the area of the opening at the bottom of the baffle plate is increased to reduce gas flow speed, then the gas flow speed is reduced, but the gas-liquid separation performance is not sufficiently enhanced
Solution Approach 1:
The patent transitions from a conventional horizontal or vertical flow path to a diagonal flow path that extends from the upper part toward the lower part of the container. This dimensional change in flow direction allows the gas-liquid mixture to collide with the second side part at an angle, enhancing separation efficiency while maintaining a compact container structure without simply enlarging the opening area.
Solution Approach 2:
The container is divided into distinct functional regions: a first side part with the gas outlet, a second side part that receives the colliding flow, and a bottom part with the liquid outlet. The flow path forming part further segments the flow into a diagonal portion and a horizontal portion, creating multiple interaction zones that improve separation performance without increasing overall device complexity.
2Reliability
If a conventional baffle plate design is used, then the structure is simple, but the gas-liquid separation performance is insufficient
Solution Approach 1:
The flow path forming part is integrated directly into the container structure, with the diagonal flow path formed by the container walls themselves rather than as a separate component. The first side part, second side part, and bottom part work together as a unified structure that provides both the separation function and the flow path guidance, reducing the need for additional complex components.
3Volume of moving object
If the container size is reduced for compactness, then the device is more compact, but the gas-liquid separation chamber volume is limited
Solution Approach 1:
By implementing a diagonal flow path that utilizes the vertical dimension more effectively, the patent achieves enhanced separation performance within a compact horizontal footprint. The diagonal portion extends from the upper part toward the lower part, maximizing the use of available volume and creating an efficient separation chamber that does not require a large overall container size.

AI summary
A gas-liquid separator including a container including an upper part, a bottom part and a side part connecting the upper part and the bottom part to form a gas-liquid separation chamber where a gas-liquid two-phase flow is separated into a gas phase and a liquid phase. The side part includes a first and second side parts opposed to each other, the container includes an inlet provided at the upper part so that the gas-liquid two-phase flow flows into and an outlet provided at the first side part so that the gas phase separated in the gas-liquid separation chamber flows out, and the gas-liquid separator further includes a flow path forming part forming an inclined flow path extending diagonally downward so that the gas-liquid two-phase flow flowed into through the inlet collides with the second side part below the outlet.
