摘要(Abstract):

为了提高粉煤灰质量,实现粉煤灰的高效脱炭技术发展,促进粉煤灰资源可回收利用,介绍了粉煤灰脱炭的3种方法,即浮选法、重选法和电选法,其中,浮选法主要依据矿物的表面性质对粉煤灰进行脱炭;重选法依据矿物密度性质的差异对粉煤灰进行脱炭分离;电选法则依据矿物摩擦带电性质的不同进行分选。同时,对粉煤灰脱炭方法的发展趋势进行了展望,建议未来应深入研究粉煤灰性质,将脱炭方法与新型选矿设备相结合进行工业化生产,创新结合方式,如采取活性油泡与旋流静态微泡浮选柱结合的方式对粉煤灰进行脱炭处理。
In order to improve the quality of fly ash,realize the high efficient decarbonization technology development of fly ash,promote recyclable resources of fly ash,fly ash decarburization were introduced in three methods,namely the flotation and gravity separation method and electric separation method.The flotation process was mainly based on the surface properties of minerals to take off the carbon from fly ash.Gravity separation method was based on the differences in mineral density properties of fly ash decarbonization separation.Electric separation method separated the minerals according to the different nature of friction charged.The development trend of decarburization method of fly ash was discussed,the properties of fly ash were the focus of the research.The decarburization method combined with a new type of mineral processing equipment for industrialized production and the innovation of combining ways should be researched.
