Coal-based solid waste lightweight high-strength aggregate as well as preparation method and application thereof
The invention relates to a coal-based solid waste light-weight high-strength aggregate as well as a preparation method and application thereof. The coal-based solid waste light-weight high-strength aggregate is mainly prepared from coal gangue and entrained-flow bed coal gasification ash through the processes of drying, crushing, sieving, mixing, pelletizing, sintering and the like. According to the coal-based solid waste light-weight high-strength aggregate provided by the invention, the light-weight high-strength aggregate is prepared by sintering by utilizing the characteristics that the coal gasification ash is amorphous and has low viscosity at high temperature and the carbon in the coal gangue and the carbon residue in the gasification ash can dissipate heat at high temperature, so that the technical process is simple, the production cost is low, the energy consumption is low, and the production cost is low. And the prepared lightweight high-strength aggregate can be applied to a plurality of fields such as the building industry and the petrochemical industry.
本发明涉及一种煤基固废轻质高强骨料及其制备方法和应用。所述的煤基固废轻质高强骨料主要是采用煤矸石掺混气流床煤气化灰渣的原料，经干燥、破碎、过筛、掺混、成球、烧结等工序制成。本发明所提供的煤基固废轻质高强骨料，利用煤气化灰渣是无定型非晶体，在高温低粘度特性，以及煤矸石中炭和气化灰渣中的残炭可以经高温后散发热量的特点，通过烧结制备轻质高强度骨料，工艺过程简单，生产成本低，而且能耗低，经济效益高，制备的轻质高强度骨料可以应用在建筑工业、石油化工等多个领域。
