Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional purification solutions are used, then flue gas can be purified, but the solutions become complex and require hazardous components
Solution Approach 1:
The invention extracts and utilizes fly ash, a waste product from power plant combustion, as the active purification agent. By taking out this previously discarded material and applying it to flue gas treatment, the solution simplifies the purification system while maintaining effectiveness, eliminating the need for complex multi-component conventional solutions
Solution Approach 2:
The purification composition serves itself by using fly ash (a waste product) as the active ingredient. The ash naturally absorbs contaminants from flue gas without requiring additional hazardous chemicals or complex processing systems, making the solution both simple and self-sufficient
2Reliability
If conventional purification solutions are used, then flue gas can be purified, but hazardous components are required
Solution Approach 1:
The invention converts fly ash, a harmful waste product from combustion processes, into a beneficial purification agent. This waste material naturally captures other harmful contaminants from flue gas, transforming a pollutant into a solution that eliminates multiple harmful substances simultaneously
Solution Approach 2:
The purification composition uses inexpensive fly ash as the active ingredient, replacing costly and hazardous chemical reagents. The composition can be readily prepared and applied without requiring expensive specialized materials, making purification accessible and environmentally safe
3Object-affected harmful factors
If fly ash is recycled into purification composition, then environmental friendliness improves, but production process complexity increases
Solution Approach 1:
The production process is segmented into simple, discrete steps: mixing fly ash with water or limewater in specific proportions (50-60% ash, 40-50% liquid), adjusting temperature to 10-30°C, and allowing settling. This segmentation makes the recycling process manageable and straightforward despite the environmental benefits
4Reliability
If temperature and mixing adjustments are made to optimize composition, then purification effectiveness improves, but process complexity increases
Solution Approach 1:
The invention optimizes purification by adjusting key parameters: maintaining temperature between 10-30°C, using specific ash-to-liquid ratios (50-60% ash, 40-50% liquid), and allowing adequate settling time. These parameter changes enhance effectiveness while keeping the process itself relatively simple and易于操作
