The invention discloses a metallurgical slag granulation-catalyst preparation and modification integrated device system and method, the system is mainly composed of four parts of a granulation system, a catalyst modification system, a waste heat recovery system and a separation and circulation system, and the working process of the system is composed of four steps of metallurgical slag granulation, catalyst modification, particle waste heat recovery and screening and recovery. According to the process, catalyst modification powder is directly adhered by utilizing the secondary coagulation characteristic of the surfaces of granulated metallurgical slag particles so that the catalyst particles with high additional value are prepared. The system not only realizes efficient recovery of waste heat of metallurgical slag particles, but also greatly improves the additional value of metallurgical slag products. 本发明公开了冶金渣粒化-催化剂制备及修饰一体化装置系统及方法，主要由粒化系统、催化剂修饰系统、余热回收系统、分离及循环系统四部分组成，其工作过程由冶金渣粒化、催化剂修饰、颗粒余热回收及筛分及回收四步组成。该工艺利用粒
