Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filter technology is used to clean scrubber fluid, then cleaning effectiveness is improved, but device complexity and maintenance requirements increase due to surveillance, service and replacement of filter components
Solution Approach 1:
The patent extracts the filtration function from traditional filter components and implements it through a disc stack centrifugal separator. The separating discs create centrifugal force to separate pollutants from scrubber fluid, eliminating the need for traditional filter elements that require surveillance, service and replacement.
Solution Approach 2:
The patent replaces the mechanical filter system with a centrifugal separation system. Instead of using physical filters that clog and require maintenance, the system uses rotational motion to generate centrifugal force, which separates pollutants based on density differences without requiring filter components.
2Reliability
If scrubber fluid volume is increased to dilute salts and reduce precipitates, then fluid cleanliness is improved, but the volume of fluid to be managed and discharged increases
Solution Approach 1:
The patent extracts pollutants and salts from the scrubber fluid through centrifugal separation and concentrates them in a separate pollutant phase. This allows the cleaned scrubber fluid to be reused without needing to increase volume for dilution, as the separation process removes contaminants directly.
Solution Approach 2:
The patent changes the physical state and concentration parameters of pollutants through centrifugal separation. By applying centrifugal force, the system separates and concentrates pollutants in a distinct phase, allowing the main scrubber fluid to maintain optimal volume while achieving cleanliness without dilution.
3Ease of operation
If scrubber fluid is bled off to maintain volume, then fluid management is improved, but pollutant carryover risk increases if not properly cleaned
Solution Approach 1:
The patent implements continuous centrifugal separation of scrubber fluid, maintaining a steady state where pollutants are continuously removed. This continuous cleaning action ensures that fluid can be bled off for volume management without risking pollutant carryover, as the separation process is ongoing and effective.
Solution Approach 2:
The system uses a control unit that monitors the scrubber fluid condition and adjusts the centrifugal separation process accordingly. This feedback mechanism ensures that fluid is properly cleaned before being bled off or recirculated, managing volume while preventing pollutant carryover through real-time monitoring and adjustment.

AI summary
A system for cleaning polluted scrubber fluid includes a disc stack centrifugal separator a separator inlet for polluted scrubber fluid, a first separator outlet for cleaned scrubber fluid, and a second separator outlet for a pollutant phase. A first transportation system transports polluted scrubber fluid to the separator inlet, a second transportation system transports cleaned scrubber fluid back to the exhaust gas scrubber, a bleed-off transportation system connected to the second transportation system bleeds off part of the cleaned scrubber fluid, a dirty drain tank connected to the bleed-off transportation system receives the bled-off scrubber fluid, and a waste reduction transportation system transports scrubber fluid from the dirty drain tank to the first transportation system. A controller receives information related to the work load of the disc stack centrifugal separator and regulates the transport of scrubber fluid based on the information.
