餐厨废油捕收剂浮选高炭粉煤灰

通过对餐厨废油进行处理，制备餐厨废油捕收剂用以处理高炭粉煤灰.分别采用机械活化试验确定高炭粉煤灰原灰的最佳机械活化时间，通过不同温度工况的浮选试验获得餐厨废油捕收剂的脱炭性能规律并同常规捕收剂煤油对比，通过FTIR、SEM、TG等技术对餐厨废油捕收剂和脱炭产物进行系统分析.结果表明：最佳机械活化时间为30min，最佳温度工况下，浮选炭热值可达到中高热值燃料要求，产物脱炭粉煤灰矿物成分可达到Ⅰ级粉煤灰标准.真正实现了"以废治废"和"变废为宝"，对环境保护、节能减排和资源的综合利用有着重要意义.

High carbon fly ash floated by kitchen waste oil collector

Kitchen waste oil collector was prepared by modifying kitchen waste oil to treat high carbon fly ash. The optimum mechanical activation time of high carbon fly ash raw ash was determined by mechanical activation test, the decarbonization performance law of the kitchen waste oil collector was obtained by flotation tests under different temperatures and compared with that of conventional collector kerosene, the collectors and decarbonization products were systematically analyzed by FTIR, SEM, TG and other techniques. The results showed that the optimum mechanical activation time was 30min, under the condition of optimum temperature, the calorific value of flotation carbon can meet the requirements of medium and high calorific value fuel, and the mineral composition of decarbonized fly ash product can reach the standard of I-class fly ash. It is of great significance to environmental protection, energy conservation and emission reduction, and comprehensive utilization of resources, which has truly realized the goal of "treating waste with waste" and "turning waste into treasure".
