Reduction-oxidation sulfur emissions (SOx) is in manufacture clinker and the equipment for manufacturing the tire

摘要

In the present invention, it describes a kind of process and device is used to reduce SOx and discharges equipment from clinker is prepared, be preheated by the raw mill of this cement and plant of burning includes cyclone preheater (1) and kiln (7). This method is unique in that, the compound of catalyst chloride form and/or several chloride cpds of mixture introduce preheater (1) and arrive uppermost cyclone stage (2 at its most up or down one, 3), this catalyst is directed down through preheater (1) to kiln (7), the logistics of the kiln exhaust gas of this partial amount contains the form of the evaporation of catalyst by from kiln (7), it is closed if extracted exhaust gas stream is cooling, there is catalyst in the form of solid, the solid matter that so solid matter and cooling waste gas stream and at least part are isolated contains catalyst recycling and introduces preheater (1) for updating.
