Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple waste gas processing devices are connected in series to remove various pollutants, then pollutant removal effectiveness is improved, but space occupancy increases
Solution Approach 1:
The patent combines multiple waste gas processing devices (scrubber, dust collector, active carbon adsorber) into a single integrated device with a common housing, allowing sequential processing of different pollutants within one unit, thereby reducing total space occupancy while maintaining removal effectiveness
Solution Approach 2:
The patent nests multiple functional components (rotating bed unit, scrubber layer, dust collection layer, active carbon layer) within a single housing structure, with each layer performing a specific pollutant removal function in sequence, achieving compact integration of series-connected processing stages
2Volume of stationary object
If multiple exhaust gas processing devices for various pollutants are arranged in a single assembly to reduce space, then space occupancy is reduced, but scrubbing solutions mix and absorption performance deteriorates
Solution Approach 1:
The patent divides the internal space into distinct segmented layers (scrubber layer with first scrubbing solution, dust collection layer with second scrubbing solution, active carbon layer) that are physically separated by blocking plates, preventing mixing of different scrubbing solutions while maintaining compact assembly
Solution Approach 2:
The patent assigns different local properties to different regions within the housing: the scrubber layer uses alkaline liquid for acidic gases, the dust collection layer uses water for particulate matters, and the active carbon layer adsorbs organic compounds, with each region optimized for its specific pollutant removal function

AI summary
A series-connected absorption high-gravity device includes a housing, a rotating bed unit, a rotating shaft connected to the rotating bed unit, a scrubber layer, a blocking plate unit, and a guiding tube. The rotatable bed unit is disposed in the housing and defines a fluid-flowing space therein. The scrubber layer is disposed in the housing, is disposed above and spaced apart from the rotating bed unit, and cooperates with the rotating bed unit to define an airflow space therebetween. The blocking plate unit is disposed in the airflow space and includes a top blocking plate and a bottom blocking plate formed with a bottom through hole. The bottom through hole has a projection area along an axis of the rotating shaft smaller than a projection area of the top blocking plate and falling entirely therewithin. The guiding tube introduces a fluid into the fluid-flowing space.
