| 摘要 | PURPOSE: To prevent odor and dust from being produced, by removing vaporized water from a drying/circulating passage, condensing and removing water vapor, and supplying non-condensable gas into a combustion chamber at specific temperature. CONSTITUTION: A dehydrated sludge 2 is supplied to a biaxial mixer 3, and a dried material 5 is supplied from a silo 6, and further a fluidized mixture 8 is dried with a drum-type drying apparatus 11 and is separated with a cyclon 12. Grains are fed to a vibrating sieve 17, and some of the grains passing through cooling silos 18, 19 is fed to a storage apparatus, etc., and part thereof is recycled. Gas from a processing/conveying apparatus and a grain cooling apparatus is heated to 750°C or higher in a combustion chamber 24 using a fossil fuel, and heat is applied to a vapor/air mixture in a drying/circulating passage, whereby an article to be processed in the drum type drying apparatus 11 is dried. The vapor/air mixture separate in the cyclon 12 is supplied to a condenser 26, and air from the silo and a moving apparatus is supplied to the combustion chamber 24 together with the air from the drying/circulating passage.
