Description

Technical Field

[0001] The utility model relates to the technical field of flue gas dry desulfurization, in particular to a flue gas dry desulfurization device for an incineration boiler. Background Art

[0002] Boilers are commonly used heat conversion equipment in industrial production, but boiler combustion produces a large amount of waste gas, of which sulfur dioxide accounts for a much higher proportion than other waste gases. Sulfur dioxide is a colorless and transparent gas and is one of the main atmospheric pollutants. Excessive emissions of sulfur dioxide can cause acid rain, which is extremely harmful to the environment and buildings. Not only that, high concentrations of sulfur dioxide can also cause conjunctivitis, acute bronchitis and other diseases. Therefore, humans developed flue gas desulfurization technology as early as the 1980s.

[0003] Flue gas dry desulfurization is a technology used to reduce the concentration of sulfur dioxide emitted by coal-fired equipment such as coal-fired power plants. Compared with traditional wet desulfurization technology, flue gas dry desulfurization has the advantages of simple operation, no sewage and acid treatment problems, low energy consumption, and conducive to chimney exhaust diffusion; but with the promotion of dry desulfurization equipment, people have found that if the by-products of the reaction of sulfur dioxide and desulfurizer are not handled properly, it is easy to cause secondary pollution to the environment. Therefore, a device is needed to process and recycle the by-products after dry desulfurization and reuse the by-products after desulfurization. Utility Model Content
