Solution Overview
Problem
The fluctuating flow rate and pressure of exhaust gas from combustion furnaces pose challenges in stabilizing the production of carbon monoxide from carbon dioxide, particularly in the reduction equipment, leading to instability in the carbon monoxide production process.
Innovation Solution
A gas production apparatus and system that includes a separation and capture section, reaction section, pressure regulating section, and flow regulating section to stabilize the production of carbon monoxide by controlling the flow rate and pressure of the separated gas containing carbon dioxide, using a reducing agent and reducing gas to convert carbon dioxide into carbon monoxide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If exhaust gas is separated and captured to produce carbon monoxide, then carbon dioxide can be converted into valuable substances, but the flow rate and pressure fluctuations cause unstable production
Solution Approach 1:
The patent applies preliminary action by installing flow rate and pressure regulating sections before the separated gas enters the reactor. These regulating sections pre-adjust the gas parameters to stable values, ensuring that the reduction reaction proceeds under consistent conditions, thereby stabilizing carbon monoxide production while maintaining efficiency.
2Manufacturing precision
If carbon dioxide is converted to carbon monoxide through reduction reaction, then valuable product gas is produced, but flow rate and pressure fluctuations reduce manufacturing precision
Solution Approach 1:
The patent segments the gas production system into distinct functional sections: a flow rate regulating section that controls gas flow, a pressure regulating section that stabilizes pressure, and a reaction section where conversion occurs. This segmentation allows each section to independently optimize its function, improving product gas consistency while keeping the overall system manageable through modular design.
