Application of Spray Drying Desulfurization Technology in Protecting Ecological Environment

  As the world's energy consumption is increasing year by year, the burning and utilization of coal, which is 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 a large area of forests. Accumulation destruction, soil and lake acidification, building corrosion, etc.

   Therefore, controlling and reducing sulfur dioxide emissions is a very important task. Among the many desulfurization technologies, the use of spray drying to remove sulfur dioxide from flue gas is a technology that has received more and more attention. This technology was researched in the 1970s and was put into commercial operation in the late 1970s. It has low investment, simple operation, high desulfurization efficiency, and no secondary pollution. Compared with the wet method widely used in flue gas desulfurization, the powder products formed by spray drying desulfurization have greater selectivity and development value.

  An important prerequisite for the wide application of spray drying rubber sulfur technology is whether it can solve the problem of reasonable development and utilization of a large amount of powdered sulfate after drying. It can be regenerated as an absorbent, and part of the dry material can be recycled. As a filling material for the earth, it can be converted into a paste retarder for cement to make granular artificial sand and gravel, which is used as a filler for building materials instead of commonly used Concrete and asphalt, etc.
