A high-efficiency ceramic flue gas treatment device includes a spray tower, an absorption tower, an SNCR denitrification system installed in a hot blast stove, a heat exchange system, a slurry circulation pump, an oxidation fan, a limestone slurry system, and a gypsum recovery system. The invention collects the flue gas containing particles, sulfur dioxide and the like produced by kilns and spray towers for centralized treatment and super-clean and smoke-free emission. After being denitrated by the SNCR denitrification system, the flue gas from the hot blast furnace enters the spray tower, absorbs heat with the kiln flue gas in the flue gas cooling section of the absorption tower, and is absorbed by the heat exchange system, enters the absorption tower to contact and react with the limestone slurry, and rises to the In the hot section, the heat of the heat exchange system is absorbed and discharged to the outside to achieve the effect of eliminating white smoke. The slurry circulation pump continuously pumps the limestone slurry provided by the limestone slurry system to the spray unit for recycling. The oxidation fan provides air and stirs for the absorption tower to speed up the reaction and precipitation of sulfide. The gypsum is conveyed and recycled through the gypsum recovery system, without environmental pollution.
Description
Technical field
The present invention relates to technical field of environment protection equipment, in particular to a kind of high-efficiency ceramic flue gas processing device.
