Application of spray drying desulfurization technology in protecting ecological environment

As the world's energy consumption increases year by year, the combustion of coal as a primary energy source releases a large amount of sulfur dioxide and the regional acid rain formed by it, which has caused serious pollution to the environment. It destroys the ecological balance and causes large areas of forests. Destruction, acidification of soil and lakes, corrosion of buildings, etc.

Therefore, controlling and reducing sulfur dioxide emissions is an important task. Among the many desulfurization technologies, the use of spray drying to remove sulfur dioxide from flue gas is an increasingly important technology. This technology was researched in the 1970s, and was 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 that is 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 drying gum sulfur technology is whether it can solve the problem of rational development and utilization of a large amount of powdered sulfate after drying. It can be regenerated as an absorbent, part of the dry material can be recycled, used as a filler in the earth, and converted into a paste retarder for cement, made into granulated artificial sand, and used as a filler for building materials instead of commonly used Concrete and asphalt.
