摘要： PURPOSE:To efficiently promote a reduction in volume and a recycle of a waste as resources by a method wherein a mixed polymer waste is continuously thermally decomposed in contact with heating elements in a rotatively movable body. CONSTITUTION:A mixed polymer waste 20 in a hopper 8 is supplied to a rotatively movable body 1 through a guide body 5 and thermally decomposed by heating mediums 2 in rotative contact with the heating mediums 2. The mixed polymer waste 20 is gasified or carbonized. The carbonized part of the mixed polymer waste 20 on the surface thereof is gasified while being ground and separated by the rotating and shearing stress of the heating mediums 2. The gasified mixed polymer waste is softened in a catalyst contact reaction tank 30, and the unsoftened content is separated by a cooling device 31. The ungasified mixed polymer waste, i.e., the carbonized part (including an inorganic substance), is transferred along an inclined angle theta to a discharge port 17 through a plurality of perforations provided in a truncated cone-shape body of the rotatively movable body 1, thereafter being reacted with water gas in a steam reaction tank 50 to be reduced in volume.

摘要： PURPOSE:To provide a mixed waste plastics-treating method intended for waste volume reduction and resource reclamation, capable of raising the decomposition rate of thermosetting resins hard to pyrolyze and gasify without the need for sorting mixed waste plastics, and designed to recover oil relatively rich in low-carbon number components. CONSTITUTION:Mixed waste plastics are fed from a reservoir 1 to a dissolving pyrolysis oven 2 where they are mixed with a solvent fed from an oil reservoir 5 and then heated to effect evaporation of the low-boiling solvent and pressurization of the oven along with dissolution of part of the waste plastics. Subsequently, by pyrolysis and gasification of the solvent and both the dissolved and undissolved mixed waste plastics the oven is pressurized to the pyrolysis pressure, and under this pressure the pyrolysis and gasification are further carried out. The resultant pyrolysis gas discharged from the oven is introduced into a catalytic cracking oven 3 where the gas is cracked by catalytic reaction. The resultant cracked gas is condensed and liquefied in a condenser 3, and the liquefied oil component is reserved in the oil reservoir 5.

摘要： PROBLEM TO BE SOLVED: To control an increase in the amount of scattering of the subject of processing in an area near the exit of a rotary drum in a rotary kiln where agitating blades are installed on the inner surface of the rotary drum.
SOLUTION: In the rotary kiln where the agitating blades are provided on the inner surface of the rotary drum and in parallel with an axis of rotation, the agitating blades are higher at the entrance side than at the exit side of the drum. A plurality of the agitating blades may be provided along the circumferential direction of the rotary drum. In the rotary kiln, the subject of processing gets drier or more carbonized and is more likely to scatter as it gets closer to the exit of the rotary drum. With the agitating blades made high at the entrance side and low at the exit side of the rotary drum, the amount that the subject of processing is lifted by the agitating blades is decreased to reduce scattering.

摘要： PURPOSE:To provide a treatment system wherein formation of dioxins can be suppressed, by incorporating therein a process for producing an oil through melt pyrolysis or carbonization pyrolysis of waste plastic and a process for high-temp. treatment above a specific temp. CONSTITUTION:Waste plastic 50 contg. an org. or inor. substance is fed into a pyrolysis oven 1 from a hopper 30 to melt and gasify only the org. substance. The resulting gas is fed via a piping 51 into a catalytic reaction oven 1, wherein it is converted into a low-boiling component, which is then cooled in a cooler 3 to obtain an org. substance as a liquefied fuel, which is then stored in an oil storage tank 4 for a while. The fuel is then passed through a piping 61, mixed with air 500, and fed into a combustion burner 11b of a high-temp. melting oven 5. Meanwhile, the non-liquefied gaseous org. substance is passed through a piping 55, mixed with air 500, and fed into a burner 11a. Dioxins in the gas and the oil are decomposed through combustion thereof with the burners 11a and 11b, and then discharged from an off-gas disposal apparatus. On the other hand, the inorg. substance from the pyrolysis oven 1 is heated together with other waste 100 contg. an inorg. substance and an org. substance in the oven 5 at 900 deg.C or above to be melted and turned into slug to thereby decrease the vol. of the waste. The slug is discharged out of the system.

摘要： PURPOSE:To temporarily store heat and effectively utilize waste heat by guiding the exhaust heat or the excessive heat generated upon incineration to a garbage pit in which the collected garbage is temporarily stored, taking out the heat applied to the garbage in the garbage pit and using the garbage pit for the storage of the garbage and heat accumulation. CONSTITUTION:Collected garbage is supplied to a garbage pit 1 from a garbage loading port 12 and temporarily stored therein until it is burnt in an incinerator 1. Then, the garbage is sequentially thrown into the incinerator 2 by a garbage crane 10 and a bucket 11 and burnt. The burnt ash 21 is collected in the lower part of the incinerator 2. Combustion gas 28 is guided to a boiler 3 to generate steam and the steam is guided to a steam turbine 7 to generate electricity by a generator 8. The steam flowing out of the steam turbine 7 is returned to the boiler 3 through a condenser 9 and reused. This return steam is fed to the garbage pit 1 to be directly heat exchanged with the garbage. Further. the combustion gas 28 is exhausted as combustion exhaust gas 29 from a funnel 5, so that a system can be effectively employed.
