Document Type and Number:
Japanese Patent JP5680450
Kind Code:
B2
Abstract:
[Problem] To process chlorine bypass exhaust gas at low cost without increasing heat loss of a cement burning system while ensuring safe operation of the cement burning system. [Solution] A device for processing chlorine bypass exhaust gas associated with a chlorine bypass system (1) which cools and extracts a part (G) of a combustion gas from a kiln exhaust gas passage from the kiln bottom of a cement kiln (2) to a lowermost cyclone and which recovers chlorine bypass dust (D6) from extraction gas (G1), the device comprising: a first dissolution tank (12) for slurrying the recovered chlorine bypass dust while adding an alkali agent thereto; a solid-liquid separation device (13) for separating solids and liquids in a slurry (S1) generated in the first dissolution tank; a second dissolution tank (14) for redissolving a cake (C1) generated in the solid-liquid separation device; and a desulfurization tower (11) for contacting a slurry (S2) after redissolution generated in the second dissolution tank with an exhaust gas (G4) of the chlorine bypass system and desulfurizing the exhaust gas.
