Description
Technical Field
The utility model belongs to the technical field of glass or the fine trade flue gas of glass handles technique and specifically relates to a recycle device of glass or the fine trade flue gas accessory substance of glass.
Background
With the development of the world industry, the atmospherePollution problems are becoming more serious, and various exhaust gas treatment technologies are being developed and applied globally. The most typical industrial kiln flue gas desulfurization techniques are various, and there are wet desulfurization including limestone-gypsum method, magnesium method, ammonia method, double alkali method, single alkali method, etc., and in addition, dry and semi-dry methods. All these methods are to remove the harmful SO in the flue gas2The SO is converted into another harmless substance (sulfate byproduct) through a chemical reaction to achieve the purpose of removing the SO from the flue gas2And (4) removing. In the wet desulfurization process, sulfate by-products exist in sewage or gypsum slurry, and because flue gas also contains other harmful and harmless gases, a large amount of dust or a small amount of other heavy metal ions and the like, the generated by-products, namely sulfate, are impure in components and too many in impurities, and are difficult to purify.
With the gradual operation of desulfurization facilities, more and more desulfurization byproducts are produced, and the comprehensive utilization of the desulfurization byproducts and the prevention of secondary pollution become important issues of urgent research at present. The national development committee on several opinions on accelerating the industrial development of flue gas desulfurization in thermal power plants clearly points out that the comprehensive utilization of flue gas desulfurization byproducts is further developed, and the development of circular economy is promoted. The research on the desulfurization by-products, especially the desulfurization gypsum, is carried out by organizing departments such as building materials, agriculture and forestry, electric power and the like and scientific research institutes, and provides instructive opinions of various utilization ways, organizes the comprehensive utilization demonstration project of the desulfurization by-products, and timely brings out compulsory measures and relevant preferential policies for comprehensive utilization of the desulfurization by-products. In addition, a policy document about enhancing the comprehensive utilization of the desulfurization by-products is also issued from various places, and the statement that "the desulfurization by-products of the coal-fired power plant must be comprehensively utilized in order to reduce secondary pollution is pointed out. The limestone-gypsum method desulfurization byproduct is suitable for being applied to building materials or cement retarders; the byproduct of the dry and semi-dry desulfurization facility is calcium sulfite which has instability and must be treated by reliable measures to prevent the pollution caused by the secondary volatilization of sulfur dioxide by the calcium sulfite. "the following is the current treatment of the main desulfurization by-products.
Treatment mode of wet desulphurization by-product
Wet processAt present, the lime-gypsum method is used for desulfurization, the by-product component is mainly gypsum, and a small amount of unreacted lime, calcium sulfite, impurities and the like exist. The desulfurized gypsum is chemically prepared from calcium sulfate dihydrate (CaSO)4·2H2O) is predominant, and is currently mainly used in the following areas:
building materials, including gypsum blocks and plasterboards, plastering gypsum, gypsum putty.
The cement retarder is characterized in that a proper amount of dihydrate gypsum must be added into portland cement to control hydration of C3A in clinker to adjust the setting time of the cement, so that the retarder not only can retard the cement, but also can improve the strength of the cement. Desulfurized gypsum is mainly used when natural gypsum is lacked or the demand for gypsum is large. Certain physical and chemical requirements must be met when the desulfurized gypsum is used in cement, and in particular, desulfurized gypsum cannot contain significant calcium chloride, which can accelerate concrete setting and reinforcement corrosion.
For agricultural use, the high air permeability of desulfurized gypsum makes it an excellent soil conditioner.
Treatment mode of secondary, dry/semi-dry desulfurization products
The dry/semi-dry flue gas desulfurization process mainly refers to desulfurization processes such as spray drying, in-furnace calcium spraying and tail humidifying activation technology, flue gas circulating fluidized bed technology, gas suspension absorption method desulfurization and the like. The desulfurization slag comprises calcium sulfite, calcium sulfate, fly ash, unused calcium-based absorbent and the like, wherein the calcium sulfite accounts for a larger proportion, and the desulfurization slag contains a higher amount of fly ash and trace elements with a higher proportion than wet desulfurization slag. The physical form of the desulphurization slag is dry powder with the water content of 1-3 percent. At present, the desulfurization slag generated by the dry method and the semi-dry method is mostly treated by a abandoning mode at home and abroad, such as backfilling a waste mine pit, selecting a special abandoning site to stack, and the like.
