Liquid Separator Resonance Chamber Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound-reducing liquid separators experience significant pressure loss in gas flow due to the use of mineral wool cushions, which also compromises sound attenuation effectiveness.
Innovation Solution
A liquid separator design that incorporates a collecting basin functioning as both a liquid collector and a resonance chamber, where the second basin chamber acts as an acoustic insulator, preventing sound transfer and allowing the first basin chamber to serve as a Helmholtz resonator, thereby reducing pressure loss while maintaining sound reduction efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If mineral wool cushions are used for sound absorption and liquid filtration, then sound attenuation is improved, but pressure loss in gas flow increases significantly
Solution Approach 1:
The invention extracts the sound absorption function from the mineral wool cushions and relocates it to a separate resonance chamber. This allows the main gas flow path to be freed from sound-absorbing materials, reducing pressure loss while the resonance chamber handles sound attenuation independently.
Solution Approach 2:
The device is segmented into functionally independent components: a main gas flow path without mineral wool, a collecting basin for liquid separation, and a separate resonance chamber for sound absorption. This segmentation allows each component to optimize its specific function without compromising the others.
2Loss of energy
If mineral wool cushions are reduced in volume to decrease pressure loss, then pressure loss is reduced, but sound attenuation effectiveness is compromised
Solution Approach 1:
The invention moves the sound absorption function from the axial dimension (within the gas flow path) to a separate dimensional space (the resonance chamber connected via side passages). This allows sound attenuation to occur in a parallel dimension without interfering with the main gas flow and pressure characteristics.
3Device complexity
If the collecting basin is designed as a simple single chamber, then device complexity is reduced, but sound reduction effectiveness is insufficient
Solution Approach 1:
The collecting basin is designed with multi-functionality: it serves as both a liquid collection chamber and incorporates an integrated resonance chamber for sound absorption. The partition wall with specific opening configurations allows the basin to fulfill multiple functions simultaneously without requiring entirely separate systems.

Function Achieved in This Case
This configuration achieves lower pressure loss in gas flow while effectively reducing sound levels by utilizing resonance-based sound reduction, with the option to incorporate additional sound-absorbing materials for enhanced performance without excessive pressure loss.
Implementation Method 1
the first basin chamber to serve as a Helmholtz resonator, thereby reducing pressure loss while maintaining sound reduction efficacy
Implementation Method 2
the second basin chamber acts as an acoustic insulator, preventing sound transfer
Implementation Method 3
oil carried in the gas stream settles on the fibers of the mineral wool and runs down under the force of gravity. The oil then drips through passage openings

AI summary
A liquid separator (10) has a horizontal main pipe (100) and a collecting basin (200) arranged sealingly on the underside of the main pipe (100). A partition wall (310) extends transverse to the main pipe (100) and divides the collecting basin (200) into first and second basin chambers (210, 220). The first basin chamber (210) is connected to the interior of the main pipe (100) via passage openings (320), and the second basin chamber (220) has an outlet opening (230). The partition wall (310) extends sealingly on the underside of the main pipe across the width of the collecting basin (200) and has a connecting opening interconnecting the first and second basin chambers (210, 220) in a fluid-conducting manner. The second basin chamber (220) has no direct connection to the interior of the main pipe (100) and the outlet opening is higher than an upper edge of the connection opening.
