APPARATUS FOR DEODORIZATION TREATMENT OF EXHAUST GAS OF DUST DRYER OF FACILITY FOR DUST SOLID FUEL PRODUCTION

摘要

PROBLEM TO BE SOLVED: To carry out deodorization of an exhaust gas of a dust dryer not by combustion deodorization by a deodorization furnace and to use a gas after the deodorization as a heat sour for the dust dryer. SOLUTION: This deodorization treatment apparatus of an exhaust gas of the dust dryer of a solid fuel production facility in which a gas G for dust drying is sent to the dust dryer 4, dust is dried, an exhaust gas G1 of drying is passed through a dust collector and deodorized is equipped with a cogeneration system apparatus 15. An exhaust gas line 6 of the dust dryer 4 is connected to the suction side of a gas turbine 16 of the cogeneration system 15 and a gas takeout line 29 branched from an exhaust line 23 of the gas turbine 16 is connected to an inlet 4a of the dust dryer 4.
