Preparation method of cast ash-based unfired carbonized ceramsite
The invention discloses a preparation method of cast ash-based unfired carbonized ceramsite, the cast ash-based unfired carbonized ceramsite is mainly prepared from the following raw materials: casting dust, fly ash, water glass, cement and an alkali activator, the dry materials are uniformly mixed to form an ash material, the ash material is put into a granulator, a water glass aqueous solution is sprayed for granulation, and a ceramsite green body is obtained; placing the prepared ceramsite in a room for aging and drying, then transferring the ceramsite into a carbon dioxide curing box for pre-curing, and finally continuously performing CO2 curing in the box to obtain the casting ash-based unfired carbonized ceramsite. The preparation method is simple and easy to implement, the raw materials are low in price and easy to obtain, a large amount of casting dust and fly ash can be consumed, and waste recycling is achieved; the ceramsite is prepared through carbon dioxide curing, the curing period is shorter, and meanwhile carbon fixation can be achieved; the prepared cast ash-based unfired carbonized ceramsite has a good fixing effect on heavy metals in the raw materials, and can be well applied to sewage treatment.
本发明公开了一种铸造灰基免烧碳化陶粒的制备方法，该铸造灰基免烧碳化陶粒主要由下列原料所制成：铸造粉尘与粉煤灰，水玻璃、水泥、碱激发剂，将上述中干料混合均匀形成灰料，放入造粒机中，喷洒水玻璃水溶液造粒得到陶粒生胚；将制得的陶粒置于室内陈化干燥后转入二氧化碳养护箱内预养护，最后继续在箱内进行CO2养护，即可得铸造灰基免烧碳化陶粒；本发明制备方法简单易行，原料价廉易得，能消耗大量铸造粉尘和粉煤灰，实现了废物再利用；采用二氧化碳养护制备陶粒，养护周期更短，同时可以固碳；对于原料中的重金属具有很好的固定作用，得到的铸造灰基免烧碳化陶粒可以很好的应用于污水处理。
