Lithium battery material calcining kiln tail gas treatment integrated process and system

The invention discloses a lithium battery material roasting kiln tail gas treatment integrated process and system. The system comprises a circulating heat exchange system, a demisting system, an absorption system, a denitration system and a discharging system. The process comprises the steps of absorption demisting and denitration discharging. The waste heat of the tail gas of the calcining kiln is recycled, resource consumption can be saved while tail gas pollutants are fully treated, the production cost is reduced, and the system is friendly to equipment and more beneficial to production. 本申请公开了一种锂电材料焙烧窑尾气处理一体化工艺及系统，该系统包括循环换热系统、除雾系统、吸收系统、脱硝系统和排放系统；该工艺的步骤包括吸收除雾和脱硝排放。其通过对焙烧窑尾气的余热进行循环回收再利用，在满足对尾气污染物进行充分处理的同时能够节省资源消耗，降低生产成本，对设备友好，更有利于生产。
