Flue gas desulfurization byproduct-based inorganic gelled material and preparation method thereof

The invention discloses a flue gas desulfurization byproduct-based inorganic gelled material and a preparation method thereof. In the material, desulfurization ash generated in flue gas desulfurization treatment of a coal fired power plant is used as a main material; and slag, gypsum and cement clinker are mixed and ground with the main material to form the inorganic gelled material. The inorganic gelled material comprises the following components in percentage by weight: 30 to 40 percent of desulfurization ash, 45 to 55 percent of slag, 3 to 5 percent of gypsum and 8 to 12 percent of cement clinker. Because the desulfurization ash is used as a raw material for preparing the inorganic gelled material, no or little natural resource is used, and secondary pollution of the desulfurization ash is reduced. The preparation method comprises the steps of raw material selection, pre-grinding, mixing and grinding. Because the mechanical means is adopted, the raw materials do not need high-temperature calcination treatment, the manufacturing process is very compact, the production cost is extremely low, high energy consumption and high pollution caused by calcination can be avoided, the energy can be greatly saved, and the requirements of energy conservation and emission reduction are met. By detection, various inspection indexes of the inorganic gelled material meet the requirement of 22.5 strength level in GB / T3183-2003 Masonry Cement, and the inorganic gelled material can fully replace the traditional product.

Non-sintered brick based on flue gas desulfurization byproduct and preparation method thereof

The invention relates to a non-sintered brick based on a flue gas desulfurization byproduct and a preparation method thereof. The brick is prepared by the following steps: desulfurated ash produced by desulfuration treatment on flue gas generated in a coal fired power plant is taken as a main material, cement, fly ash, gypsum and sand are taken as auxiliary materials, water is added into the main material and the auxiliary materials, the mixture is evenly stirred and then is subject to compression moulding to obtain the brick, wherein the solid raw materials contain the following components by weight percent: 30-35% of the desulfurated ash, 10-15% of the cement, 5-10% of the fly ash, 3-5% of the gypsum and 40-50% of the sand; and the adding amount of the water accounts for 10-12% of the total weight of the solid raw materials. Because the brick takes the desulfurated ash as the raw material instead of solid clay, and natural resources are not used or used as little as possible, which avoids the damage on land resources owing to taking clay and reduces secondary pollution of the desulfurated ash. The preparation method comprises the steps of taking raw materials, mixing the raw materials, carrying out compression moulding and carrying out later-period consevation. The brick is not subject to high temperature sintering treatment, thus energy consumption is greatly reduced, and the protection and the improvement on ecological environment can be achieved more easily. Tests indicate that the non-sintered brick has strength grade greater than or equal to MU 10 grade, and can fully replace the traditional solid clay brick.
