摘要
本文介绍了固体颗粒冲击、机械搅拌、转鼓粒化、离心粒化和风淬等国外的高炉炉渣余热回收系统,对我国应用高炉炉渣余热回收处理技术的现状进行了总结。在比较国内国外同类技术的优缺点后,指出基于离心粒化技术的余热回收系统具有粒化性能优异、回收效率高等优点,据此认为有必要进一步研究该系统运行能耗、系统稳定性和控制参数以及渣粒的处理能力和粒径的均匀性等问题,以尽早实现商业化应用。
Described were blast furnace slag waste heat recovery systems based on such technologies from foreign countries as solid particle impingement,mechanical agitation,rotary drum granulation,centrifugal granulation and air quenching etc. and summarized were the current status of the application of blast furnace slag waste heat recovery and treatment technologies in China. After the authors have compared the merits and demerits of the same kind technologies both in domestic and abroad,they pointed out that the waste heat recovery system based on the centrifugal granulation technology boasts excellent granulation performance and a high heat recovery efficiency etc. On this basis,they believed that it is necessary to further study the operating power consumption,stability,control parameters and slag particle treatment capacity of the system as well as the uniformity of the particle diameters etc. in a hope to realize its commercial applications as soon as possible.
