As the world ’s energy consumption increases year by year, the combustion and utilization of coal as a primary energy source has released a large amount of sulfur dioxide and the regional acid rain formed by it, which has caused serious pollution to the environment. It has destroyed ecological balance and caused large areas of forest Accumulation and destruction, acidification of soils and lakes, corrosion of buildings, etc.

Therefore, controlling and reducing the emissions of sulfur dioxide is an important task. Among the many desulfurization technologies, spray drying to remove sulfur dioxide from flue gas is an increasingly important technology. This technology was researched in the 1970s and has been put into commercial operation in the late 1970s. It has less investment, simple operation, high desulfurization efficiency, and no secondary pollution. Compared with the wet method widely used in flue gas desulfurization, the powder product formed by spray drying desulfurization has greater selectivity and development value.

 An important prerequisite for the widespread application of spray-dried gum sulfur technology is whether it can solve the problem of reasonable development and utilization of a large number of powdered sulfates after drying. It can be regenerated as an absorbent, and some dry materials can be recycled. As a ground filler, it can be converted into a plaster retarder for cement. It can be made into granular artificial sand and stone. Concrete and asphalt, etc.
