Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grease filters in ventilating systems face challenges in maintaining efficiency due to pressure drop and noise issues when air with oil particles passes through, and they are difficult to clean, leading to reduced performance over time.
Innovation Solution
A grease filter design featuring detachable baffle plates with guide units that direct air currents, including inclined inlet and outlet guides, and a path structure that separates and redirects air flow to enhance oil collection efficiency while minimizing pressure drop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grease filter interrupts the flow of oil particles to collect them, then oil collection efficiency is improved, but pressure drop increases and energy efficiency degrades
Solution Approach 1:
The grease filter is divided into multiple channels, each with its own baffle plate and guide unit. This segmentation allows the air flow to be distributed across multiple paths, reducing the pressure drop in each individual channel while maintaining overall oil collection efficiency through the combined effect of all channels.
Solution Approach 2:
The invention introduces a vertical dimension by stacking multiple channels above and below a reference plane. This three-dimensional arrangement allows air flow to occur in multiple levels simultaneously, increasing the total filtration area without proportionally increasing the pressure drop, as each channel operates semi-independently.
2Reliability
If the grease filter interrupts the flow of oil particles to collect them, then oil collection efficiency is improved, but flow noise and vibration noise increase
Solution Approach 1:
By dividing the filtration function across multiple channels with individual baffle plates, the invention reduces the intensity of flow disruption in each channel. This segmentation distributes the noise-generating flow interruptions across multiple locations, reducing overall noise and vibration levels while maintaining effective oil particle collection.
Solution Approach 2:
The vertical stacking of channels creates a three-dimensional filtration system where noise and vibration from individual channels are spatially distributed. This dimensional arrangement allows noise to dissipate in multiple directions rather than concentrating in a single plane, reducing the perceived noise level.
3Reliability
If oil particles accumulate on the grease filter, then oil collection efficiency is maintained, but cleaning difficulty increases and filter efficiency cannot be continuously maintained
Solution Approach 1:
The modular channel structure with detachable baffle plates allows the filter to be segmented into manageable units for cleaning. Each channel can be accessed and cleaned independently, making the overall cleaning process more manageable and less time-consuming compared to a monolithic filter design.
Solution Approach 2:
The baffle plates are designed to be movable or detachable, allowing dynamic access to the filtration surfaces for cleaning. This dynamic design enables easy removal and repositioning of components during maintenance, significantly improving cleaning ease while allowing the filter to maintain its efficiency over extended periods.
