Method for preparing cordierite mullite from aluminum ash
The invention discloses a method for preparing cordierite mullite from aluminum ash. The method comprises the following steps: (1) pretreatment of aluminum ash; (2) proportioning; (3) ball milling; (4) stirring; (5) dehydrating; (6) pre-drying; (7) forming; (8) drying; and (9) calcining. Talc and clay raw materials are added to prepare the cordierite-mullite composite material. The problem that the aluminum ash cannot be directly used due to low ammonia removal efficiency in wet ammonia removal of the aluminum ash is solved, the problem of high raw material cost is solved by in-situ synthesis of the cordierite-mullite composite material from the treated aluminum ash, and meanwhile, the purposes of waste utilization, environmental protection and energy conservation are achieved.
本发明公开一种铝灰制备堇青石莫来石的方法，包括如下步骤：（1）铝灰的预处理；（2）配比；（3）球磨；（4）搅拌；（5）脱水；（6）预干燥；（7）成型；（8）干燥；（9）煅烧。添加滑石和黏土原料制备堇青石‑莫来石复合材料。不仅实现了铝灰湿法除氨中存在除氨效率不高造成不能直接使用的问题，也利用处理后的铝灰原位合成堇青石莫来石复合材料，解决了原料成本高昂的问题，同时达到废物的利用，环保节能。
