AI Technical Summary
In existing technologies, when using low-concentration carbon dioxide gas for solid waste carbonization and artificial reef preparation, the gas-liquid-solid mass transfer resistance is large and the reaction rate is slow, which leads to the need to add a high-energy-consuming gas purification process and increase the preparation cost.
By employing low-concentration carbon dioxide flue gas pretreatment, and through an enhanced mass transfer carbonization reactor and dynamic stirring mechanism, a microporous structure is generated in the mold using a porous gas distribution plate and transient decompression technology, thereby achieving inorganic mineralization reaction and avoiding the gas purification process.
This technology enables the direct utilization of low-concentration carbon dioxide, reduces energy consumption, generates microporous artificial reef prefabricated components suitable for marine organism attachment, and lowers manufacturing costs.
