Gas-Liquid Separator Exhaust Pipe Structure for Reliable Liquid Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas-liquid separation devices suffer from poor assembly reliability between the exhaust pipe and housing due to gaps for oil discharge, requiring long liquid discharge paths and multiple sealing points, which complicates assembly and increases the risk of sealing failures.
Innovation Solution
A gas-liquid separation device design that includes a flow diversion cavity between the exhaust pipe and the bottom end plate, allowing direct liquid discharge into a separate channel, reducing the need for sealing points and simplifying the liquid discharge path, while ensuring reliable assembly through separate inner and outer pipe components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gap for discharging oil is reserved at the fitting position between the exhaust pipe and the housing, then liquid discharge is enabled, but assembly reliability between the exhaust pipe and the housing deteriorates
Solution Approach 1:
The exhaust pipe is divided into an inner pipe and an outer pipe, creating a segmented structure. The inner pipe contains the exhaust channel while the outer pipe provides structural support and forms the fitting position with the housing. This segmentation allows the gap to be intentionally designed between the inner and outer pipes rather than at the exhaust pipe-housing interface, thereby maintaining assembly reliability while enabling liquid discharge functionality.
2Ease of operation
If a gap for oil discharge is arranged at the exhaust pipe housing interface, then liquid discharge path is established, but the liquid discharge path becomes long and requires many sealing parts
Solution Approach 1:
The liquid discharge function is extracted from the exhaust pipe-housing interface and relocated to the annular space between the inner and outer pipes. The gap is now positioned at the end of the inner pipe where it connects to the outer pipe, allowing liquid to be discharged directly into the annular space and then guided to the collection container. This extraction shortens the liquid discharge path and reduces the number of sealing requirements.
3Reliability
If the exhaust pipe and housing are tightly assembled, then assembly reliability is improved, but liquid discharge becomes difficult
Solution Approach 1:
The inner pipe is nested within the outer pipe, forming a concentric structure. The exhaust channel is contained within the inner pipe, while the annular space between the inner and outer pipes serves as the liquid discharge path. This nested configuration allows the exhaust pipe and housing to be tightly assembled for reliability, while the annular space provides a dedicated channel for liquid discharge without requiring gaps at the housing interface.
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
Enhances assembly reliability, simplifies the liquid discharge path, reduces sealing points, and lowers production costs by shortening assembly time and inventory needs, while improving the collection and discharge efficiency of separated liquids.
Implementation Method 1
The flow diversion cavity is in communication with the outlet of the liquid reservoir and the inlet of the liquid discharge channel to configure the gas-liquid separation device in such a manner that the liquid flowing out of the outlet of the liquid reservoir enters the flow diversion cavity, and the liquid flowing out of the flow diversion cavity directly enters the inlet of the liquid discharge channel.
Implementation Method 2
The separation assembly is disposed in the separation chamber and used to perform gas-liquid separation on the gas-liquid mixture entering the separation chamber.
Implementation Method 3
The exhaust pipe has an exhaust channel and a liquid discharge channel. The exhaust pipe passes through the through-opening to allow gas separated by the separation assembly to flow through the exhaust channel.
Implementation Method 4
A liquid reservoir is defined by the bottom end plate and used to receive liquid separated by the separation assembly.
