Method and device for curing carbonized product by using flue gas
The invention relates to a method and device for curing a carbonized product with flue gas, and the method comprises the following steps: (1) pre-curing a carbonized product green body A to obtain a carbonized product green body B; the pre-curing comprises one or more of heat energy input drying pre-curing and CO2 pre-curing; (2) curing the carbonized product green body B to obtain a carbonized product; wherein CO2 gas sources adopted in CO2 pre-curing and CO2 curing are smoke, and the CO2 volume concentration in the smoke is larger than or equal to 5%. According to the invention, the flue gas is used as a CO2 gas source, so that the enrichment cost of CO2 and the pollution of CO2 in the flue gas to the environment are reduced; excessive moisture in the product is discharged through pre-curing, CO2 gas can be diffused into a matrix in the subsequent curing process, re-dispersion of moisture in the product is promoted in combination with standing treatment, and the mechanical property and the carbon absorption amount of the carbonized product are effectively improved; the production efficiency is high.
本发明涉及一种用烟气养护碳化制品的方法及装置,包括以下步骤:(1)将碳化制品坯体A进行预养护,得到碳化制品坯体B;所述预养护包括热能输入干燥预养护和CO2预养护中的一种或多种;(2)将碳化制品坯体B进行养护,得到碳化制品;其中,CO2预养护和CO2养护中采用的CO2气体源均为烟气,所述烟气中CO2体积浓度≥5%。本发明利用烟气作为CO2气体源,降低CO2的富集成本和烟气中CO2对环境的污染;通过预养护将制品中的多余水分排出,利于后续养护过程中CO2气体扩散到基体内部,结合静置处理促进制品内部水分重新分散,有效提升碳化制品的力学性能和吸碳量;生产效率高。
