Baking-free brick prepared from coal gasification waste residues and preparation method thereof
The invention discloses a baking-free brick prepared from coal gasification waste residues and a preparation method thereof, belongs to the field of environmental protection, and solves the problems of low utilization rate of coal gasification waste residues and high energy consumption in preparation of baking-free bricks from the residues in the prior art. The product is prepared from coarse slagand/or fine slag of a gasification furnace, cement, water and a soil stabilizer. The method comprises the steps: 1, taking raw materials; 2, putting coarse slag and/or fine slag of the gasification furnace and cement into a first mixing bin to be mixed and then taking out to be put into a second mixing bin together with a soil stabilizer and water to be mixed, and then performing normal-temperature compression molding and natural curing . The maximum use amount of the coal gasification slag can reach 95%, and the coal gasification slag can be treated on a large scale. The coal gasification waste residues are adopted to manufacture the baking-free brick, firing, aging, steam curing and natural curing are not needed, real energy conservation, environmental protection and green production are achieved, the brick belongs to the baking-free brick in the real sense, the process is simple, the cost is low, the production period is short, and the baking-free brick is suitable for large-scaleapplication and popularization. The baking-free brick is applied to resourceful treatment of the coal gasification waste residues.
采用煤气化废渣制造的免烧砖及其制造方法，它属于环保领域。它解决了现有煤气化废渣利用率低以及利用残渣制备免烧砖存在能耗大的问题。产品：由气化炉粗渣和/或细渣、水泥、水和土体稳定剂制成。方法：一、取原料；二、气化炉粗渣和/或细渣、水泥放入第一混料仓中混合，取出后与土体稳定剂和水共同放入第二混料仓中混合，然后进行常温压制成型和自然养护。本发明中煤气化炉渣的用量最大可达95％，可大规模处理煤气化废渣。采用煤气化废渣制造免烧砖，无需烧制、陈化和蒸汽养护，自然养护即可，真正的节能环保，绿色生产，属于真正意义上的免烧砖，且工艺简单，成本低，生产周期短，适合大规模推广使用。本发明应用于煤气化废渣的资源化处理。
