As the world's energy consumption increased year by year, as a primary energy coal burning the use of the release of a large number of sulfur dioxide and the formation of regional acid rain, the environment has caused serious pollution, it destroyed the ecological balance, causing a large area of forest Product destruction, soil lake acidification, building corrosion and so on.
Therefore, the control and reduction of sulfur dioxide emissions is a very important task. In many desulphurization technologies, the use of spray drying to remove sulfur dioxide from flue gas is an increasingly important technology. The technology was developed in the 1970s and was put into commercial operation in the late 1970s. It is less investment, simple operation, high efficiency of sulfur removal, no secondary pollution, and flue gas desulfurization in a large number of wet compared to the use of spray drying desulfurization powder products have greater selectivity and development value.
Spray drying glue sulfur technology can be widely used in an important prerequisite is to solve a large number of dry powder sulfate after the rational development and utilization of the problem. Can be recycled as an absorbent, part of the dry material can be recycled, as the earth's additives, into a paste for the cement of the retarder, made of granular artificial gravel, as a building material filler instead of commonly used Concrete and asphalt.
