Gas-Liquid Separator With Curved Ribbon Terminal And Nested Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas-liquid separators face issues with separation performance due to liquid re-scattering at the terminal end of the swirling flow generating ribbon and require large installation spaces, especially in limited spaces like internal combustion engine exhaust pipes.
Innovation Solution
A gas-liquid separator design featuring a helically twisted swirling flow generating ribbon with a terminal end configuration that includes specific terminal points and edges, and a pipe structure with an inner pipe inserted into the exhaust port, guiding liquid to the inner surface by centrifugal force, and a drain port for efficient liquid separation and reduced installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional swirling flow generating ribbon with a straight terminal edge is used, then the structure is simple, but liquid re-scatters into the gas reducing separation performance
Solution Approach 1:
The terminal edge of the swirling flow generating ribbon is configured with a curved shape instead of a straight edge. Specifically, the terminal edge includes a first terminal edge extending from the first terminal end point to the middle terminal end point, and a second terminal edge extending from the second terminal end point to the middle terminal end point, forming a curved configuration that prevents liquid re-scattering while maintaining structural simplicity
2Reliability
If a double pipe structure with large diameter second pipe is used, then gas and liquid can be separately discharged, but the installation space becomes too large for limited spaces like exhaust pipes
Solution Approach 1:
The inner pipe is inserted into the exhaust port of the inlet pipe, creating a nested configuration where one pipe structure is placed within another. This nested doll approach allows the gas-liquid separator to achieve separate discharge of gas and liquid while minimizing the overall installation space required, making it suitable for limited spaces such as internal combustion engine exhaust pipes

AI summary
To provide a gas-liquid separator that can improve the separation performance of a liquid attached to a swirling flow generating ribbon and can reduce a required installation space. A gas-liquid separator includes the inlet pipe (21) and an inner pipe (22). The inlet pipe (21) receives a swirling flow generating ribbon (30), and includes an exhaust port (21a) through which a separated gas flows out and a drain port (21b) through which a separated liquid flows out. The outer diameter of the inner pipe (22) is smaller than the inner diameter of the inlet pipe (21). An end of the inner pipe is inserted into the exhaust port (21a) and is open at a location downstream of the swirling flow generating ribbon (30). A terminal end (31) of the swirling flow generating ribbon (30) includes a first terminal edge (32a) and a second terminal edge (32b). The first and second terminal edges (32a, 32b) connect a first terminal end point (31a), a second terminal end point (31b), and a middle terminal end point (31c). The first terminal end point (31a) is in one of radially outward ends and the second terminal end point (31b) is in the other of the radially outward ends. The middle terminal end point (31c) is closer to the side where the gas-liquid two-phase fluid flows in than the first and second terminal end points (31a, 31b) and is on an axial line (O).
