Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional carbon dioxide recovery apparatuses use chemical absorption solutions or electrochemical cells, then carbon dioxide separation can be achieved, but equipment costs and complexity increase significantly
Solution Approach 1:
The invention extracts and eliminates the complex equipment components (circulation path, heating device, concentrating cell, potential applying device) from conventional CO2 recovery systems, retaining only the essential elements needed for the simplified water-based dissolution process
Solution Approach 2:
The invention replaces expensive, complex equipment with a simple, low-cost water-based system that uses readily available materials, significantly reducing equipment costs while maintaining CO2 recovery functionality
2Device complexity
If simple water agitation is used to dissolve carbon dioxide, then equipment costs are reduced, but carbon dioxide recovery efficiency becomes lower than expected
Solution Approach 1:
The invention introduces a rotary mixing section with multiblade rotors that dynamically agitates the water and carbon dioxide mixture, transforming the static simple agitation into an optimized dynamic mixing process that significantly enhances CO2 dissolution efficiency
Solution Approach 2:
The invention changes the mixing parameters by using multiblade rotors with specific blade counts and configurations, optimizing the mixing intensity and water circulation patterns to maximize CO2 absorption efficiency while maintaining system simplicity
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
The apparatus efficiently recovers carbon dioxide by dissolving it in water through bubble compression, achieving higher recovery rates and reducing environmental load compared to conventional methods.
Implementation Method 1
a space encompassed by protrusions of one of the six-blade rotors and one of the protrusions of the other six-blade rotor is reduced in cubic capacity. The bubbles are compressed with the reduction in the cubic capacity of the space thereby to be refined
Implementation Method 2
water is supplied through the water supply opening into the first chamber and a carbon dioxide-containing gas is supplied through the inlet into the first chamber to be dissolved in the water

AI summary
A pump housing of the carbon dioxide-containing gas recovery apparatus is formed with a first chamber and a second chamber partitioned by a partition wall. The first and second chambers and communicate with each other through a third chamber. The first chamber communicates with a water supply opening and a carbon dioxide-containing gas inlet. When blown against water filling the first chamber, a carbon dioxide-containing gas is dissolved in the water, and the carbon dioxide-containing gas remaining undissolved exists as bubbles in the water. When a pair of six-blade rotors oppositely disposed on two axes and in the third chamber compress the bubbles to be refined into different bubbles, the carbon dioxide-containing gas can further be dissolved in the water by a compression action. An aqueous solution of carbon dioxide-containing gas is discharged from a water outlet communicating with the second chamber.
