The invention discloses a digestion process of calcium carbonate. The digestion process specifically comprises the following steps: S1, preparing materials; s2, intermittent digestion treatment; s3, heat exchange and digestion acceleration treatment; s4, flue gas treatment; the invention relates to the technical field of lime slaking processing. According to the calcium carbonate slaking process, through cooperative arrangement of the driving assembly, the intermittent feeding assembly, the hopper and the slaking assembly, the purpose of automatically and intermittently conveying lime from the hopper into the slaking assembly is achieved, the smoke generation amount is reduced, meanwhile, circulating pushing of water in the slaking assembly can be achieved in the process, full contact of the lime and the water is guaranteed, and the slaking efficiency is improved. The arrangement of a heat exchange flow channel and an acceleration assembly is matched, heat generated by the reaction of lime and water is absorbed through one-way circulating flow of heat exchange liquid between the heat exchange flow channel and the acceleration assembly, meanwhile, heat exchange fins can be driven to enable a heat exchange barrel to rotate, and the reaction speed of the lime and the water is further increased; and high-efficiency guarantee is provided for digestion of calcium carbonate.
本发明公开了一种碳酸钙的消化工艺，具体包括以下步骤：S1、备料；S2、间歇消化处理；S3、换热加速消化处理；S4、烟气处理；本发明涉及石灰消化加工技术领域。该碳酸钙的消化工艺，通过驱动组件、间歇上料组件、料斗和消化组件的配合设置，实现将石灰从料斗中自动间歇输送至消化组件中的目的，降低烟气产生量的同时，在过程中还可以实现消化组件中水的循环推动，保证石灰与水的充分接触，配合换热流道和加速组件的设置，利用换热液体在换热流道和加速组件之间的单向循环流动，实现对石灰与水反应产生热量的吸收同时，还可以驱动换热翅片使换热筒进行转动，进一步提高石灰与水的反应速度，为碳酸钙的消化提供高效化保障。
