Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of active carbon molded bodies faces challenges in uniform mixing of active carbon particles with molding-purpose binders, leading to segregation and defective products, which hampers the production efficiency and purification performance.
Innovation Solution
The use of granulation-purpose fibrous binders to aggregate active carbon particles into granules, eliminating the need for molding-purpose binders and enhancing the specific surface area for improved purification performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If molding-purpose binder is mixed with active carbon particles, then active carbon can be molded, but uniform mixing is difficult and binder segregation occurs leading to defective products
Solution Approach 1:
The invention divides the active carbon into granules of controlled size (0.3mm to 1.7mm) before molding. This segmentation allows the granules to be more uniformly mixed with the binder compared to fine particles, reducing segregation during molding and improving manufacturing precision while maintaining ease of manufacture.
Solution Approach 2:
The invention changes the particle size parameter of active carbon to an optimal range (0.3mm to 1.7mm) that balances moldability and mixing uniformity. This parameter optimization ensures that the active carbon granules are large enough to resist segregation but small enough to be effectively bound, resolving the contradiction between ease of manufacture and manufacturing precision.
2Reliability
If smaller particle diameter active carbon is used, then purification performance is improved, but filtration flow rate may be affected
Solution Approach 1:
The invention optimizes the particle diameter parameter to a specific range (0.3mm to 1.7mm) that balances purification performance and filtration flow rate. This parameter optimization ensures sufficient contact area for high purification performance while maintaining adequate pore spaces for acceptable filtration flow rate, resolving the contradiction between reliability and productivity.

AI summary
An active carbon molded body that comprises a plurality of active carbon granules that are formed from aggregates of active carbon particles. The active carbon granules include a fibrous granulation binder. The active carbon molded body is formed as a result of the plurality of active carbon granules being aggregated by means of the fibrous granulation binder in the active carbon granules.The present invention is also an active carbon molded body production method in which active carbon granules that have been formed by aggregating active carbon particles by means of a fibrous binder are molded by simultaneous application of heat and pressure without separate addition of a molding binder.The present invention thereby provides: an active carbon molded body that has high purification capacity and good production efficiency; and a production method for the active carbon molded body.
