微波技术在云南煤系高岭岩脱硅实验中的应用

利用微波辐照技术对云南峨山煤系高岭岩进行了脱硅实验,结果表明:与传统脱硅技术相比,利用微波技术能够有效地加快煤系高岭岩的烧结速率、降低能耗和节约时间;经微波处理的煤系高岭岩的A l2O3/S iO2值可由0.498提高到3.10以上,因此可作为理想的铝资源加以利用;利用微波技术对煤系高岭岩进行脱硅处理,烧结时间、细度、脱硅反应时间和液固比是影响脱硅效率的重要因素。

Application of Microwave Radiation Technology in Silicon Removal from Coal-series Kaolinite in Yunnan

The experimental research on application of microwave radiation technology in silicon removal from Yunnan E′shan coal series kaolinite is briefly introduced in this paper.The results showed that,compared with conventional silicon removal technology,the microwave radiation technology can greatly speed up sintering speed,reducing energy consumption and shortening sintering time.As a result of microwave treatment,the value of Al2O3/SIO2 of coal series kaolinite can be increased from 0.498 to 3.10,thus,this coal series kaolinite can be used as ideal aluminum resources.During the process of silicon removal treatment of coal series kaolinite by microwave technology,the sintering time,fineness,reaction time of silicon removal and the solid-to-liquid ratio are important factors influencing efficiency of silicon removal.
