Exhaust method based on concentration of carbon dioxide in flue gas and application thereof
The invention relates to the technical field of concrete building materials, in particular to an exhaust method based on the concentration of carbon dioxide in flue gas, which specifically comprises the following steps of: exhausting for the first time when the temperature reaches K0 + (K1-K0)/(n + 1); when the temperature reaches K0 + (K1-K0) * 2/(n + 1), exhausting for the second time; when the temperature reaches K0 + (K1-K0) * 3/(n + 1), exhausting for the third time; exhausting for the fourth time when the temperature reaches K0 + (K1-K0) * 4/(n + 1), and exhausting for the nth time when the temperature reaches K0 + (K1-K0) * n/(n + 1); after exhausting to normal pressure every time, re-supplementing the flue gas until the pressure of the reaction kettle is P, and maintaining the pressure to a corresponding temperature; wherein the exhaust frequency in the reaction process is n, the initial temperature of the mineralization reaction is K0, and the final temperature of the system is K1.
本发明涉及混凝土建筑材料技术领域，具体为一种基于烟气中二氧化碳浓度的排气方法，具体为：当温度达K0+(K1‑K0)/(n+1)第一次排气；当温度达K0+(K1‑K0)×2/(n+1)第二次排气；当温度达K0+(K1‑K0)×3/(n+1)第三次排气；当温度达K0+(K1‑K0)×4/(n+1)第四次排气···当温度达K0+(K1‑K0)×n/(n+1)第n次排气；每次排气至常压后重新补充烟气至反应釜压力为P，保压至对应的温度；其中，反应过程中的排气次数为n，矿化反应的初始温度为K0，体系最终温度为K1。
