Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If natural iron ores and quartz stones are mixed and modified with CaO through ultrasonic impregnation, then the specific surface area and porosity are enhanced, but the preparation process complexity increases
Solution Approach 1:
The patent utilizes porous natural iron ores and quartz stones as the base material structure. The porous nature of these materials provides inherent high surface area, which is further enhanced by the ultrasonic impregnation process that creates additional porosity and surface area for HCl adsorption.
Solution Approach 2:
CaO acts as an intermediary substance in the ultrasonic impregnation process. It is impregnated into the porous structure of the iron ore-quartz mixture, serving as the active component that reacts with HCl while the porous carrier material provides the surface area and structural support.
2Productivity
If the specific surface area of the dechlorinating agent is increased, then the dechlorination activity and chlorine capacity are improved, but the strength of the dechlorinating agent may be compromised
Solution Approach 1:
The patent creates a composite material system combining natural iron ores, quartz stones, and CaO. The iron ore and quartz provide structural strength and stability, while CaO provides the active dechlorination function. This composite structure allows high surface area and activity without sacrificing mechanical strength.
Solution Approach 2:
The CaO is selectively impregnated into the porous regions of the iron ore-quartz composite, concentrating the active dechlorination components in specific high-surface-area regions while the bulk material maintains its structural integrity and strength.
3Object-generated harmful factors
If existing dechlorinating agents are used, then HCl removal is achieved, but the cost is high and reutilization rate is low
Solution Approach 1:
The patent employs inexpensive natural materials (iron ores and quartz stones) as the base carrier, replacing expensive synthetic adsorbents. While the material may have limited reutilization cycles, the low cost of the raw materials makes the overall process cost-effective.
Solution Approach 2:
The natural iron ore and quartz stone materials are used in their naturally occurring forms with minimal processing required. The ultrasonic impregnation with CaO is a simple enhancement that leverages the inherent properties of the natural materials rather than requiring extensive synthetic processing.
