Replaceable Surface Adsorption Rotor for Faster Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adsorption rotors require full replacement when performance degrades, leading to high costs and material waste, especially in integral and divided types, and fixed-type dust-collectors result in clogging issues without effective desorption.
Innovation Solution
An adsorption rotor design allowing only the deteriorated surface side to be replaced, with a structure that enables easy detachment and attachment by modifying metal aggregates, maintaining the same outer diameter and promoting turbulent airflow for improved performance, reducing exchange time and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an integral-type adsorption rotor is used, then the initial manufacturing cost is comparatively cheap, but when performance deteriorates the entire rotor must be replaced resulting in excessive time and effort for exchange and increased replacement cost
Solution Approach 1:
The adsorption rotor is divided into a non-detachable base portion and a detachable surface side portion. The surface side portion can be removed and replaced independently without replacing the entire rotor, thus reducing exchange time and effort while maintaining reasonable initial manufacturing costs.
2Ease of manufacture
If an integral-type adsorption rotor is used, then the initial manufacturing cost is comparatively cheap, but heavy industrial equipment is needed during exchange resulting in increased replacement cost
Solution Approach 1:
By segmenting the rotor into detachable surface side portions, the replacement process becomes simpler and does not require heavy industrial equipment, thus reducing replacement cost while maintaining low initial manufacturing cost.
3Ease of repair
If a divided-type adsorption rotor is used, then sectors can be easily exchanged resulting in decreased exchange cost, but the initial cost is comparatively high due to strengthening every sector piece
Solution Approach 1:
The rotor is segmented into a non-detachable base portion and detachable surface side portions. This segmentation allows easy exchange of only the deteriorated surface portions without requiring strengthening of entire sector pieces, thus reducing initial cost while maintaining low exchange cost.
4Reliability
If a fixed-type dust-collecting filter is equipped, then contamination prevention is achieved, but the rotor width becomes wider and clogging occurs more easily without effective desorption
Solution Approach 1:
The dust-collecting filter is integrated into the detachable surface side portion rather than being a fixed separate component. This allows the filter to be removed and replaced along with the surface side portion, enabling effective desorption and preventing clogging while maintaining compact rotor dimensions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient replacement of only the surface side, reducing exchange time and cost by up to one-third, maintaining performance and avoiding material waste, while allowing operation during maintenance and using unskilled personnel.
Implementation Method 1
An adsorption rotor functions as either an absorber of volatile organic compounds (hereafter called 'VOC') which are then released to make them denser, or as a dehumidifier by adsorbing moisture in air
Implementation Method 2
adsorbed VOCs can be desorbed nearly completely by passing desorption air having a high temperature of not less than 300° C.
Implementation Method 3
promoting turbulent airflow for improved performance

AI summary
An adsorption rotor has a surface layer which can be detached and replaced when performance degrades. A metal aggregate is extended in the width direction of the rotor element so that attachment-and-detachment adsorption rotor elements can be attached thereto using bolts and a perimeter griddle fixing bracket, thus resulting in protecting an upper part of the integral-type adsorption rotor element. In this way, the weight of the attachment-and-detachment adsorption rotor elements can be made light, resulting in them being fixable only using bolts, without special tools or skilled technicians. Moreover, because the detachment-and-replacement procedures can be performed from a rotor spindle side, thus from inside of a chamber, a heavy industrial machine is not required.
