Foamed concrete carbon sequestration method
The invention provides a foamed concrete carbon sequestration method which comprises the following steps of: mixing crushed solid wastes with cement, and stirring the mixed raw materials and hot water to obtain hot slurry; introducing treated clean flue gas generated by a boiler into the hot slurry to enable CO2 in the clean flue gas to react with the hot slurry and complete a cement foaming process; injecting the foamed slurry into a shaping mold for foaming and solidification; feeding the foamed brick obtained after solidification into a carbonation curing chamber, and introducing clean flue gas into the carbonation curing chamber to enable CO2 in the clean flue gas to conduct carbonation curing on the foamed brick; and carrying out autoclaved curing and drying on the foamed brick subjected to carbonation curing by utilizing steam generated by the boiler or steam extracted by a steam turbine. Clean flue gas discharged by a boiler is directly introduced into concrete slurry, aeration and bubble reaction are utilized, and then a hardening reaction is performed for a certain time, so that the foamed concrete brick for directly fixing flue gas and CO2 is formed, and capture, storage and utilization of CO2 in the flue gas are realized at low cost.
本申请提出一种发泡混凝土碳封存方法，包括将粉碎后的固体废弃物与水泥混合，混合后的原料和热水搅拌得到热浆料；向所述热浆料中通入锅炉产生的处理后的净烟气，以使所述净烟气中的CO2与所述热浆料反应并完成水泥发泡工艺；将发泡后的发泡浆料注入定型模具发泡凝固；将凝固后得到的发泡砖送入碳酸化养护室，向碳酸化养护室中通入净烟气，以使所述净烟气中的CO2对发泡砖进行碳酸化养护；将碳酸化养护的发泡砖利用锅炉产生的蒸汽或汽机抽汽进行蒸压养护和干燥。直接将锅炉排放的净烟气通入混凝土浆液，利用曝气和气泡反应，然后再经过一定时间的硬化反应，形成直接固定烟气及CO2的发泡混凝土砖，成本低廉地实现烟气中的CO2的捕集、封存和利用。
