Gas-Liquid Separator Layout to Block Liquid Slugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas-liquid separators in compression systems have a limited separation effect, allowing large-particle liquids to enter the compressor, causing damage due to liquid impact, especially under high super-cooling conditions.
Innovation Solution
A gas-liquid separator design featuring an outer cylinder, input and output pipes with specific orientations, and a blocking part with an avoidance hole, positioned to prevent large-particle liquids from entering the output pipe, ensuring only gas enters the compressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional gas-liquid separator is used, then the structure is simple, but the gas-liquid separation effect is poor and large-particle liquids cannot be separated
Solution Approach 1:
The separator is divided into multiple functional zones using blocking parts with different configurations (first blocking part, second blocking part, third blocking part). Each blocking part creates a specific region (first region, second region, third region) with different separation functions, allowing progressive separation of gas and liquid phases while maintaining structural organization
Solution Approach 2:
The blocking parts act as intermediary structures between the gas-liquid mixed flow and the output. These blocking parts with avoidance holes provide a controlled path that allows gas to pass through while blocking large-particle liquids, serving as a mediator that facilitates selective phase separation
2Reliability
If the separator allows simple flow through, then the structure is simple, but liquid refrigerants flow into the compressor causing damage
Solution Approach 1:
The blocking parts are positioned upstream in the flow path to preemptively block large-particle liquids before they can reach the compressor. The first blocking part with its avoidance hole configuration creates a preliminary barrier that stops liquid refrigerants in advance, preventing potential compressor damage before it occurs
Solution Approach 2:
Different blocking parts are designed with different local characteristics - the first blocking part has a specific avoidance hole configuration for initial separation, while the second and third blocking parts have different configurations for subsequent separation stages. Each blocking part is optimized for its specific location and function in the separation process
