Summary: | The invention discloses a cement kiln flue gas carbon capture and utilization integrated system and process, and belongs to the technical field of carbon dioxide capture and utilization. The system comprises a cement kiln flue gas pretreatment unit, a flue gas carbon dioxide capture unit and a cement admixture preparation-storage-addition unit. The specific process comprises the following steps: introducing flue gas into a cement kiln flue gas wetting and heat exchange device, then introducing wetting liquid into an absorbent stirring kettle, adding organic amine organic components and alkali metal compound components to obtain an absorbent, and introducing the absorbent into an absorption tower to be mixed with the wetted flue gas to obtain absorption liquid; and introducing the mixture into a cement admixture stirring kettle, adding a polyhydric alcohol organic matter, and finally adding the mixture into a cement grinding mill to finish trapping and utilization. According to the invention, trapping of carbo |
