Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oil fume purification systems in the catering industry are inadequate, leading to significant air pollution and increased construction and energy costs, with existing extractor hoods lacking complete purification standards and often causing blocked fume discharge and backflow, which negatively impact indoor living environments.
Innovation Solution
A dual-purpose circulating purifier that combines oil fume purification with fresh air supply, utilizing a housing with integrated oil fume and fresh air devices, including grease and dust separators, purification filters, and a heat exchange system, along with a double-wing baffle device to enhance fume absorption and protection, allowing for efficient indoor air purification without pipeline discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional adapter-tube emptying technology is used for oil fume emission, then construction costs are reduced, but air purification effectiveness deteriorates and pollution emissions increase
Solution Approach 1:
The patent combines oil fume purification and fresh air supply into a single integrated device. The housing contains both the oil fume purification device with grease separator and fume purification filter layer, and the fresh air supply device with dust blocker and gas purification filter layer, merging two separate functions into one unit that addresses both pollution removal and fresh air provision simultaneously.
Solution Approach 2:
The circulating purifier performs multiple functions: it purifies oil fume through grease separation and filtration, supplies fresh air through separate filtration and circulation, recycles heat energy, and prevents pollution emissions. This multi-functional design resolves the contradiction by providing comprehensive air quality improvement without requiring multiple separate systems.
2Device complexity
If centralized shared fume channels are used for multi-storey discharge, then construction complexity is reduced, but fume backflow and blocked discharge occur affecting indoor environment
Solution Approach 1:
The patent extracts the purification function from the traditional discharge-only system. Instead of simply venting fumes through shared channels, the invention incorporates a complete purification system with grease separators and filter layers that process and clean the air before discharge, eliminating backflow and blocking issues by ensuring proper filtration at the source.
Solution Approach 2:
The device performs self-purification through its integrated grease separator and filter layers that automatically process incoming air and fumes. The circulation system recycles cleaned air back into the environment, and the heat exchange device recovers energy, making the system self-sufficient and reliable without requiring complex external infrastructure.
3Object-affected harmful factors
If high purification standards are implemented, then air quality improves, but energy consumption and construction costs increase
Solution Approach 1:
The patent converts the harmful hot waste fumes into a beneficial resource through the heat exchange device. The heat absorber captures thermal energy from the purified air, and the heat storage tank stores this energy for later use in preheating fresh air or space heating, transforming waste heat into a useful resource that reduces overall energy consumption while maintaining high purification standards.
Solution Approach 2:
The system recovers and reuses purified air through the circulation device that returns cleaned air to the indoor environment, and recovers heat energy through the heat exchange system. This recovery approach reduces the need for continuous high-energy operation of fans and filters, lowering overall energy consumption while sustaining air quality improvements.
