Key word:Application of spray drying desulfurization technology in protecting ecological environment

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

Therefore, controlling and reducing emissions of sulfur dioxide is a very important task. Among the many desulfurization technologies, the use of spray drying to remove sulfur dioxide from flue gas is an increasingly important technology. The technology began in the 1970s and was put into commercial operation in the late 1970s. It has low investment, simple operation, high sulfur removal 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 wide application of spray-dried rubber 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, and some dry materials can be recycled. As a filling of the earth, it is converted into a retarder for cement as a paste, and it is made into granular artificial sand. It is used as a filler for building materials instead of commonly used. Concrete and asphalt.
