Gas-Liquid Separator and Compression System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing gas-liquid separation systems in compression systems take a long time to start up again after shutdown, as high-pressure gas returns to the gas-liquid separator and is discharged, affecting working efficiency.
Innovation Solution
A gas-liquid separator with a one-way valve and filter assembly is integrated into the compression system, where the one-way valve opens when a pressure difference reaches a predetermined value, allowing unidirectional communication and preventing reverse gas flow, ensuring the compressor's pressure is maintained during shutdown, thus accelerating start-up when resumed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gas-liquid separator allows free communication between inlet and outlet, then gas-liquid separation function is maintained, but high-pressure gas returns to separator after shutdown causing long start-up time
Solution Approach 1:
The patent extracts the harmful reverse flow of high-pressure gas from the system by introducing a one-way valve that blocks the outlet path during shutdown, while maintaining normal gas-liquid separation function during operation through pressure differential activation
Solution Approach 2:
The one-way valve acts as an intermediary component between the gas-liquid separator and the compressor, controlling the direction of gas flow and preventing harmful reverse flow while allowing normal operation, thus resolving the contradiction between maintaining separation function and reducing start-up time
2Loss of time
If a one-way valve is added to prevent reverse gas flow, then compressor start-up time is shortened, but device complexity increases
Solution Approach 1:
The one-way valve is designed to automatically open or close based on the pressure differential between inlet and outlet, without requiring external control systems or additional actuators, thus minimizing the increase in device complexity while achieving the goal of reducing start-up time

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 shortens the compressor's start-up time by preventing gas discharge from the separator during shutdown, ensuring faster and more efficient reactivation.
