| titleOfInvention | Cement self-desulfurization device and method |
| abstract | The invention provides a cement self-desulfurization device and a cement self-desulfurization method. The device comprises a decomposing furnace, a waste heat boiler, a plurality of preheaters and an outlet pipeline of the uppermost-stage preheater; the both ends of top preheater outlet duct connect top preheater and exhaust-heat boiler respectively, it still includes: one end of the hot flue gas extraction pipeline is connected with the decomposing furnace; the outlet pipeline of the uppermost-stage preheater is provided with a connector at a position close to the uppermost-stage preheater; the hot flue gas extraction pipeline is connected with the outlet pipeline of the uppermost preheater through the interface and is used for conveying the flue gas containing hot raw materials, which is extracted from the decomposing furnace by the hot flue gas extraction pipeline, into the waste heat boiler through the outlet pipeline of the uppermost preheater. By the method and the device, the hot raw materials generated in the cement production process are utilized to carry out the dry desulfurization of the flue gas, the efficiency of the conventional dry desulfurization of the cement flue gas is obviously improved, and the equipment investment and the operation cost are reduced, so that the method and the device are more practical. |
