Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a single adsorbent resin system is used for purification, then the stability of hydrogen peroxide is improved, but the removal efficiency of organic carbon and cations is insufficient
Solution Approach 1:
The purification system is segmented into multiple stages: a primary purification system using an adsorbent resin to remove organic carbon and cations, followed by a secondary purification system using electrodeionization to remove remaining impurities. This segmentation allows each stage to specialize in removing specific types of impurities, achieving both high stability and high purity that a single system cannot accomplish alone.
2Manufacturing precision
If electrodeionization system is used without prior adsorbent resin treatment, then purification is achieved, but the performance and stability of the electrodeionization system deteriorates rapidly
Solution Approach 1:
The adsorbent resin treatment is performed as a preliminary action before the electrodeionization process. The adsorbent resin pre-removes organic carbon and cations from the crude hydrogen peroxide, preparing the feedstock for electrodeionization. This preliminary action prevents the electrodeionization system from being overwhelmed by high concentrations of organic impurities, thereby maintaining its performance and stability over time.
3Manufacturing precision
If conventional purification methods are used, then the process is simple, but high-purity hydrogen peroxide cannot be produced efficiently
Solution Approach 1:
The invention changes the operational parameters of the purification process by using an adsorbent resin with specific adsorption characteristics optimized for organic carbon and cation removal, followed by electrodeionization with controlled electrical parameters. This parameter optimization allows the system to achieve high purity output while maintaining efficient operation and high yield, overcoming the limitations of conventional single-stage methods.
