Combined preparation process of cement and biochar
The invention relates to the technical field of cement and biochar preparation, and discloses a combined preparation process of cement and biochar, which combines a cement preparation process with a biochar preparation process to fully utilize materials and energy, reduce cost and reduce environmental pollution. The method comprises the specific combined steps that waste gas generated in a rotary kiln of the cement preparation technology is recycled and then conveyed to a drying step of the biochar preparation technology, waste utilization is carried out, gas components and heat in the waste gas are used for optimizing the performance of the prepared biochar, and meanwhile energy is saved; the waste heat in the rotary kiln and the hot material warehouse in the cement preparation process is recovered into the heat exchanger, and then the waste heat is distributed to the drying and carbonization combustion steps of the biochar preparation process for secondary heat utilization, so that energy is fully saved, and external energy consumption in the biochar preparation process is reduced. After combination, the energy utilization rate is high, the cost is low, the material quality is better, and remarkable advantages are achieved.
本发明涉及水泥及生物炭制备技术领域，本发明公开了一种水泥及生物炭的联合制备工艺，将水泥制备工艺与生物炭制备工艺进行联合，以充分利用物料和能源，降低成本和减少环境污染。具体联合步骤包括：将水泥制备工艺的回转窑中产生的废气经过回收后将其输送至生物炭制备工艺的烘干步骤中，进行废物利用，利用废气中的气体成分和热量优化制备的生物炭的性能同时节约能源；将水泥制备工艺中的回转窑和热料库中的余热回收至热量交换器中，随后再将其分配给生物炭制备工艺的烘干和碳化燃烧步骤中进行热量二次利用，充分节约能源，减少生物炭制备过程中的外部能源消耗。联合后能源利用率高、成本低、物料质量更好，具有显著的优势。
