Solution Overview
Problem
Catalyst powders generated during loading in existing rotary spread-type catalyst loading devices can cause clogging, uneven flow, and environmental and health hazards due to mutual friction and breakage within the reactor.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If catalyst is delivered by rotary spread type without air flow, then catalyst can be broadly dispersed in reactor, but catalyst granules break and generate catalyst powders due to mutual friction
Solution Approach 1:
The patent applies pneumatic principles by introducing air flow along the catalyst delivery path. The air delivery unit generates a flow that carries catalyst granules from the feeder to the rotor, reducing direct contact and friction between granules. This pneumatic assistance maintains loading efficiency while preventing catalyst breakage and powder generation.
2Device complexity
If catalyst granules are delivered without air flow assistance, then delivery structure is simple, but catalyst powders accumulate between granules causing differential pressure and uneven flow
Solution Approach 1:
The air delivery unit provides pneumatic assistance during catalyst delivery, creating a controlled air flow that prevents powder accumulation between granules. This maintains reliable and uniform reactor flow while adding only moderate complexity to the delivery structure through the integration of air delivery components.
3Productivity
If catalyst powders are generated during loading, then loading process is fast, but environmental and health problems occur due to powder leakage
Solution Approach 1:
The air delivery unit creates a controlled pneumatic environment that contains catalyst granules during loading, preventing powder generation and leakage. This maintains fast loading speed while eliminating environmental and health hazards by keeping the catalyst in a controlled air flow state throughout the delivery process.
