Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oil separators do not effectively capture small amounts of oil remaining in the air after the initial separation process, leading to a low oil trapping rate.
Innovation Solution
An oil separator design incorporating a combination of an impingement member made of urethane foam and a glass fiber filter, where the glass fiber filter is strategically positioned to trap oil particles of varying sizes, enhancing the oil trapping efficiency by utilizing inertial impaction and Brownian motion trapping mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If only an impingement member is used for oil separation, then large oil particles can be trapped, but small oil particles remain in the discharged air
Solution Approach 1:
The oil separation function is segmented into two distinct mechanisms: the impingement member handles large oil particles through inertial impaction, while the glass fiber filter captures small oil particles through diffusion and interception. This segmentation allows each component to be optimized for its specific particle size range, achieving comprehensive oil removal without excessive complexity
Solution Approach 2:
The invention employs a glass fiber filter, which is a porous material with intricate internal structures and large specific surface areas. The porous structure provides numerous capture sites for small oil particles through diffusion and interception mechanisms, significantly enhancing the trapping of fine particles that the impingement member cannot capture
2Quantity of substance
If a glass fiber filter is added to capture small oil particles, then oil trapping rate increases, but device complexity and pressure loss increase
Solution Approach 1:
The impingement member performs preliminary separation by removing large oil particles before the air reaches the glass fiber filter. This preliminary action reduces the oil particle load on the filter, allowing it to operate more efficiently with lower pressure drop, thereby reducing the energy required by the compressor
Solution Approach 2:
The invention optimizes the parameters of the glass fiber filter, including fiber diameter, filter thickness, and porosity, to achieve the right balance between oil trapping efficiency and pressure loss. By carefully selecting these parameters, the filter maintains high effectiveness for small particle capture while minimizing resistance to air flow

AI summary
The objective is to improve the oil trapping rate of an oil separator. The oil separator separates gas and liquid in air containing oil, recovers liquid that contains oil. The oil separator is provided with an introduction port for introducing air, an oil trap for trapping oil contained in air, a reservoir for storing the liquid flowing out of the oil trap, and a discharge port for discharging air from which oil has been removed. The oil trap includes a glass fiber filter and an impingement member, which traps oil particles by causing the oil particles to strike the impingement member.
