When drying 2, the hot air from the hot air generator 55 is supplied from the upstream side to the downstream side of the dryer 54,
This high-temperature hot air is generated by the self-ignition temperature of the waste 52 (230 ° C.).
), The inside of the dryer 54 is extremely high temperature, and if there is fine dust, dried paper, cloth, etc. in the waste 52, there is a risk of ignition. Further, since the dryer 54 itself has a long cylindrical shape, the waste 52 near the upstream side has a high moisture content,
Since the waste 52 near the downstream side has a low water content, the waste 52 near the downstream side can be sufficiently dried with low-temperature hot air instead of high-temperature hot air. Therefore, the dryer 5
On the downstream side of 4, the drying efficiency is low.

This pretreatment device 1 is provided with municipal waste (for example, kitchen waste, books,
A coarse crusher 3 (first crusher) (for example, a biaxial crusher having a blade width of about 50 mm is used) for crushing waste 2 such as lump garbage slightly coarsely; A magnetic separator 4 for magnetically separating waste 2 crushed by the above to remove iron and the like, and a high-temperature exhaust gas discharged from an incinerator or the like is introduced to heat clean air to generate hot air at 140 ° C. to 250 ° C. 5, a rotary kiln type dryer 6 for guiding the hot air 5 from the heat exchanger to dry the waste 2 from which iron has been removed by the magnetic separator 4; The low-moisture content (average moisture content of less than 10%) and high-moisture content (average moisture content of 10% or more) dried wastes 7 and 8 installed near the discharge port and dried by the dryer 6 are fed by wind power (upflow). )
And a cyclone 10 for guiding the low-moisture content dry waste 7 selected by the wind-selection device 9 together with the hot air 5 to separate and collect the low-moisture content dry waste 7. And a fine crusher 11 (second crusher) for guiding the high-moisture content dried waste 8 which has been sorted and dropped downward by the wind separator 9 and further crushed to reduce its particle diameter to 10 mm or less. (For example, a cutter mill is used), and the high-moisture-content dry waste 8 crushed by the fine crusher 11 is supplied to the dryer 6 again. Dust in the hot air 5 after drying the waste 2 is also collected in the cyclone 10 and mixed with the low-moisture content dry waste 7, and the gas 12 discharged from the cyclone 10 Is a deodorizing device 1
The air is discharged to the atmosphere via the air blower 3 and the exhaust fan 14.

It is transported to 6. Next, the waste 2 is introduced into the dryer 6 and the waste 14 is supplied from the heat exchanger.
It is dried with hot air 5 at a temperature of 0 ° C. to 250 ° C. to become a dried waste. The temperature of the hot air 5 is 140 ° C. to 180 ° C.
It is preferably in the range of ° C.

Is done. In this wind separator 9, the low-moisture content dry waste 7 is lifted upward by the upward flow because of its small apparent specific gravity, while the high-moisture content dry waste 8 (eg, kitchen garbage, litter, etc.) Has a large apparent specific gravity, and thus falls downward against the upward flow.

The waste 2 in the dryer 6 can be completely and efficiently dried with the hot air 5 at a temperature of 140 ° C. to 250 ° C., which is much lower, and therefore, ignition in the dryer 6 can be prevented. Further, since the hot air 5 is heated by the exhaust gas of the incinerator, the fuel for the hot air 5 may be unnecessary.
