<p>PROBLEM TO BE SOLVED: To reduce the capacity of an activated carbon type deodorizing unit, to control differential pressure of a refuse pit to prevent leakage of odor, to facilitate an operation of a hot stove for dryer or a deodorizing furnace, and to deodorize odor air as a combustion air of an incinerating furnace when the furnace is installed in parallel with an RDF manufacturing facility. SOLUTION: Odor air is collected from respective odor generating zones of an RDF manufacturing apparatus 1 to a refuse pit 2. Part of the collected odor air is sent from the pit 2 to a hot stove for a dryer or deodorizing furnace as combustion air. Simultaneously, its residue is sucked from the pit 2 by a deodorizing fan 6 through a deodorizing unit 5 so that the pit 2 is always held at a negative pressure. A differential pressure between the pit 2 and a platform 9 or the atmosphere is detected by a differential pressure gage 11, and an odor air amount is controlled so that the detected value falls within a predetermined range. Thus, the unit 5 is controlled to be operated.</p> |
