| 摘 要： | 介绍了一套按快速床设计(气速约2 m/s)建设的生石灰循环流态化反应装置上开展的冷模研究.通过对石灰颗粒的特性、流态化行为及磨损规律等研究,经过数学推导,建立了床层稳态粒子模型.该模型可在给定生石灰加入量、床料卸出量及生石灰粒径分布的情况下,预测稳态时的床层石灰藏量及其粒径分布,从而将为反应动力学研究提供脱硫剂床层的基础参数,促进这项新工艺的技术开发和工业应用.

| Abstract: | The cold\|modeling study conducted on a lime circulating fast\|bed fluidized reactor system designed with a gas velocity of up to 2 m/s is described.Through studies on the characteristics of the lime particles and its fluidizing and wearing behaviors,in combination with mathematic derivation,a steady\|state fluid\|bed particle model has been established.Using this model,when the amount of the feed and bed discharge as well as the lime feed particle size distribution have been given,the steady\|state bed inventory and its particle size distribution can be predicted.These data will provide basic information for the study of reaction kinetics and enhance the development and industrial application of this novel technology. |
